TL;DR.Kāore e taea te whakawhiti i te karāhe borosilicate me te karāhe houra-raima i roto i ngā takai whakapaipai. Ko te tauwehenga whānui wera o te whānau borosilicate he 3.3 x 10^-6/K, e manawanui ana ki te ru wera ΔT o te 160 nekehanga Celsius, ā, e tutuki ana i te akomanga wairākau USP <660> HGA 1. Ko te tauwehenga whānui o te whānau houra-raima he 9 x 10^-6/K, e manawanui ana ki te ΔT o te 40 nekehanga Celsius, ā, e tutuki ana i te akomanga wairākau USP <660> HGB 3. E toru ngā āhuatanga e whakatau ana i te whakatau: te pāmahana o te raina whakakī, te pH o te hanganga, me te roa o te wā e hiahiatia ana. Ko te whakakī wera i runga ake i te 70 nekehanga Celsius, te pH o te hanganga i raro iho i te 4, i runga ake rānei i te 9, te roa o te wā i runga ake rānei i te 24 marama e tohu ana i te borosilicate. Ko te whakakī pāmahana rūma, te pH kūpapa, me te roa o te wā e pupuri ana i te houra-raima hei paerewa.

Ngā Whānau Karāhe e Rua: Te Porosilicate me te Soda-Lime Tahatahi

He mea hanga te karāhe borosilicate i runga i te silica me te boron trioxide, me te ihirangi B2O3 i te 12% ki te 15% o te tauira. Ka whakakapia e te boron ngā waikura konutai me te konupūmā e hanga ana i te karāhe houra-raima, ā, ko taua whakakapinga kotahi te mea e akiaki ana i te nuinga o ngā rerekētanga āhuatanga o raro. He teitei ake te pāmahana whakawhiti karāhe, he tata ki te hautoru te whānui o te wera, ā, he maha ngā wā ka roa ake te mau o te matū ki te wai me ngā otinga waikawa.

Ko te karāhe houra-raima te mea tino kaha o te umanga takai whakapaipai. Ko te hanganga he tata ki te 70% te silica, 15% te konutai waikura, 9% te konupūmā waikura, me te toenga o te konupūmā, te konumohe, me ngā huānga iti. He iti ake te utu ki te hanga, he māmā ake te hanga ki roto i te whānuitanga o ngā āhuahanga pounamu whakapaipai e tumanakohia ana e te mākete, ā, ka taea te hangarua katoa mā te awa cullet matua. Ko ngā āhuatanga e hanga ana i te houra-raima he iti te utu me te whai hua ka taea hoki te whakaraerae ki te ru wera me te mimiti kawakore i raro i ngā āhuatanga waikawa.

E toru ngā meka hanganga e ārahi ana i te nuinga o ngā raraunga i roto i te toenga o tēnei whakataurite. Tuatahi, ko te boron i roto i te borosilicate he kaihanga whatunga karāhe, ko te tikanga ka hono tika ki te whatunga silica, ā, ka puta he hanganga kiato ake, he pumau ake i te wera. Tuarua, ko te konutai i roto i te houra-rima he whakarerekē whatunga, ko te tikanga ka noho ki roto i ngā āputa o te whatunga silica, ā, ka mimiti ina pāngia e te wai, e ngā otinga waikawa rānei. Tuatoru, ko te korenga o te boron i roto i te houra-rima te mea e āhei ai te whakarite i te whakatakotoranga kia mārama me te hanga kia kaua e ātete ki te wera, ki te matū rānei.

I te rārangi whakaputa, ka kitea te rerekētanga i waenga i ngā whānau karāhe e rua i roto i ngā mahi e toru. Ka tirotirohia e mātou te ipu i mua i te utaina o te puranga kia mau tonu te tae me te tauwehenga whānui i roto i te awhi kua tohua e te kaiwhakarato. Ka inehia e mātou te tauwehenga whānui wera i runga i te tauira i tangohia mai i ia oumu, ā, ka whakakorehia e mātou tetahi tauira e neke atu ana i te 0.2 x 10^-6/K mai i te uara kua whakapuakina e te kaiwhakarato. Ka tirohia e mātou te matotoru o te pakitara o te pounamu i muri i te hanganga, nā te mea ko te matotoru o te pakitara te mea e whakatau ana i te manawanui ΔT tuturu i runga i te raina whakakī nui atu i te whānau karāhe tonu. He pai ake te pounamu borosilicate pakitara 2.0mm i te pounamu houra-raima pakitara 1.5mm i runga i te raina kotahi, ā, ka kite mātou i tēnei e puta ana i roto i ngā kaute whakakore a te kiritaki i mua i te putanga mai ki te taiwhanga.

Ko te hua o te mahi, mō ngā whakamahinga whakapaipai katoa, ina neke atu i te 60 nekehanga Celsius te pāmahana o te pounamu i te wā e whakakīia ana, i raro iho rānei i te pH 4, i runga ake rānei i te pH 9 i te wā e mau ana te pounamu, ko te whiriwhiri i te karāhe te mea e whakatau ana mēnā ka tae atu te hua ki te kaihoko me te kore he pakaru.pounamu hinu kakaraKa kapi te whānuitanga i ngā whānau karāhe e rua, ā, ko te kōwhiringa kei te whakahaeretia e te taupānga kaua e te manakohanga taunoa.

Ātete Ru Wera: Te Rerekētanga ΔT me tōna Tikanga mō te Pounamu Whakataka 30ml

Ko te pūwāhi raraunga tino nui mō te raina whakakī whakapaipai ko te rerekētanga pāmahana ka taea e te pounamu te noho i waenga i te taha wera o te whakakī me te taha matao o te wetewete, te kawe rānei i raro iho. Ka taea e te whānau borosilicate te tu atu ki te ΔT o te 160 nekehanga Celsius i raro i te whakamātautau ru wera paerewa. Ka taea e te whānau houra-raima te tu atu ki te ΔT o te 40 nekehanga Celsius i raro i te whakamātautau kotahi.

Mō tētahi raina whakapaipai whakakī wera noa e rere ana i te 80 nekehanga Celsius me te kaikawe i raro i te pāmahana i te 22 nekehanga Celsius, ko te rerekētanga he 58 nekehanga Celsius.karāhe borosilicate me te tauwehenga whānui 3.3 x 10^-6/KKa hipa te pounamu i tēnei whakawhiti me te reiti whakakorenga i raro i te 0.1%. Ka pakaru te pounamu houra-raima me te reiti whakakorenga o te 2% ki te 5% i te tīmatanga tuatahi, ā, ka pakaru haere i te mahana haere o te raina. Ko te rerekētanga 2% ki te 5% ko te rerekētanga i waenga i te raina whakakī e tika ana me te raina ka whakahokia ki te kaiwhakarato pounamu hei tirotiro i te pūtake.

Mō tētahi raina whakapaipai whakakī-matao noa e rere ana i te 22 nekehanga Celsius me te heke iho i te 18 nekehanga Celsius, ko te rerekētanga he 4 nekehanga Celsius. Ka paahitia e ngā whānau karāhe e rua tēnei whakawhiti me te kore he reiti whakakorenga e taea te ine. Kāore e tika te utu borosilicate mō ngā raina whakakī-matao, ā, ka puta te utu tāpiri hei whakahekenga tawhē tika me te kore he pikinga pono o te raina whakakī.

He mea nui anō hoki te rerekētanga o te ru wera ki te taha o te kaihoko. Ka taea e te pounamu borosilicate te neke mai i te kaukau wera i te 38 nekehanga Celsius ki te pouaka whakamātao i te 4 nekehanga Celsius me te kore e pakaru, koia te take ko te borosilicate te paerewa mō ngā serum whakakī-wera e hokona ana i ngā rohe e tika ana kia pouaka whakamātao te kaihoko i muri i te whakatuwheratanga. Ka taea e te pounamu houra-raima te neke mai i te whata 30 nekehanga Celsius ki te pouaka whakamātao 4 nekehanga Celsius, engari kāore e taea te neke mai i te para whakakī-wera 60 nekehanga Celsius ki te horoi 20 nekehanga Celsius me te kore he para.

Mō te whakatakotoranga pounamu maturuturu 30ml, ko te whakaritenga mahi kia ora te pounamu i te hekenga pāmahana whakakī 50 nekehanga Celsius ki te kawe whakamatao 25 ​​nekehanga Celsius. Ka whiti ngā whānau karāhe e rua i tēnei whakawhiti, engari he iti ake te tawhiti wera o te pounamu houra-raima, ā, he tairongo ake ki ngā aukati raina i te wā e whakamatao ana te pito wera o te whakakī i te mea e whāngai tonu ana ngā pounamu. Mā te aukati raina 10 meneti i te 50 nekehanga Celsius me te houra-raima ka puta he tere whakakorenga ine i runga i te kawe makariri e whai ake nei; kāore e kitea te aukati raina kotahi me te borosilicate e te kaute whakakorenga.

Raraunga Hototahi Matū: pH 2 ki te pH 11 puta noa i te Waipiro, te Hinu, me ngā Whakatakotoranga Wai-Tuhinga

Ko te hototahi matū te wāhi e tino rerekē ai ngā whānau karāhe e rua. Ko te Borosilicate i te akomanga hydrolytic HGA 1 kāore e whakaatu i te whakahekenga taumaha ine, kāore he nekehanga pH ine, ā, kāore he whakaekenga mata ine puta noa i te awhe pH 2 ki te pH 11 katoa i raro i te pakeketanga tere i te 40 nekehanga Celsius mō ngā marama 12. Ko te houra-koima i te akomanga hydrolytic HGB 3 kāore e whakaatu i te whakaekenga ine i te awhe pH 5 ki te pH 8, engari he whakaekenga ine i roto i ngā awhe pH 2 ki te pH 4 me te pH 9 ki te pH 11.

E mārama ana te tikanga whakaeke i roto i te houra-raima. Ka whakawhitiwhiti ngā katote konutai i roto i te whatunga silica me ngā katote hauwai i roto i te hanganga, ka piki ake te pH o te hanganga, ka hanga he paparanga angiangi kua horoia ki te mata o roto o te pounamu. Ko te tere horoi he tata ki te 0.1 ki te 0.3 maikoromita ia tau i te pH 7, engari ka tere ake ki te 1 ki te 3 maikoromita ia tau i te pH 3, pH 10 rānei. He angiangi te paparanga kua horoia kia kore e kitea, ā, he matotoru hoki kia kore ai e pumau ngā matū hohe e pāngia ana e te pH.

Mō ngā hanganga kei roto i te waipiro me te nui o te etanoru i runga ake i te 20%, kāore he whakaekenga ine i ngā whānau karāhe e rua. He whakarewa tiaki karāhe te waipiro i roto i te hanganga nā te mea ka whakaroa i te tauhohenga whakawhiti katote. Mō ngā hanganga kei roto i te hinu tae atu ki ngā ranunga hinu kakara, kāore he whakaekenga ine i ngā whānau karāhe e rua puta noa i te awhe pH katoa; kāore te hinu e whakawhiti katote me te whatunga silica. Ka whakamātauhia e mātou te matihiko hototahi matū ki teraraunga tohutoro hototahi matū borosilicate vs houra-raimahei tūāpapa, nā te mea ka hopukina e ngā raraunga hototahi matū kua whakaputaina te āhuatanga rongoā kino rawa atu, ā, ko ngā takai whakapaipai katoa e paahitia ana ngā tikanga whakamātautau ōrite ka paahitia te whakamātautau ture whakapaipai i te taunoa.

Ko te hua whaihua mō te ranunga hinu kakara, ko te whiriwhiri i te karāhe e ārahihia ana e te matū o te hinu kakara, kaua e te pounamu. Ko ngā hinu citrus he nui te ihirangi citral, ngā hinu clove he nui te ihirangi eugenol, me ngā hinu hinamona he nui te ihirangi cinnamaldehyde, he waikawa ngawari katoa, ā, ka tere ake te mimiti i roto i te houra-raima. Mō te pounamu hinu kakara 30ml i hangaia mō te ranunga citrus, ko te momo borosilicate te whakaritenga haumaru ake. Mō te ranunga hinu kawe 30ml kāore he matū hohe kaha, he pai te houra-raima.

Mō ngā matū tiaki kiri kei te pH i raro i te 4, tae atu ki te waikawa glycolic, te waikawa lactic, te waikawa salicylic, me ngā hanganga waikawa ascorbic, ko te whakatakotoranga borosilicate te paerewa. Kāore e taea te whakatutuki i te roanga o te oranga o te 24 marama i te pH 3.5 i roto i te houra-rima nā te mea ka piki ake te pH o te hanganga mā te 0.3 ki te 0.7 waeine i roto i te 12 marama, he nui tēnei hei pana i te hanganga ki runga ake i te matapihi pH whai hua o te matū. Mō ngā matū tiaki kiri kei te pH i runga ake i te 9, tae atu ki ētahi hanganga AHA-kore me ētahi whakatakotoranga niacinamide, ka whai mana anō hoki.

Ka taea e te pounamu borosilicate te ora i te rerekētanga 160°C i roto i te taiwhanga, engari i runga i te raina tūturu ko te rerekētanga mahi ko te tau taiwhanga i wehea e te tauwehenga haumaru o te 2 ki te 3. Ko te rerekētanga mahi o te pounamu houra-raima ko te tau taiwhanga i wehea e te tauwehenga haumaru o te 3 ki te 5. Mā ngā tau ka whakamōhio i te tirotiro raina o ia rā: mēnā kei te tuku pounamu te raina i te 50°C ki te kawe 20°C, kei te 30°C o te tawhē mahi te pounamu houra-raima, ko te pounamu borosilicate kei te 60°C ki te 70°C o te tawhē mahi.

Te Wāhi e Toa ai te Houra-Raima: Te Utu, te Māramatanga o te Whatu, me te Āhua Ā-Mīhini

Ko te karāhe houra-raima te whiringa tika mō te nuinga o ngā tono pounamu whakapaipai, ā, ehara te whiringa tika i te mea uaua. Ko ngā āhuatanga e toru e hanga ana i te houra-raima hei paerewa ko te utu, te māramatanga whatu, me te āheinga hanga ā-ringa.

Mō te utu, he 30% ki te 60% te iti ake o te utu mō te houra-rima i ia pounamu i te borosilicate i te āhua ōrite. Ko te rerekētanga utu e ahu mai ana i te utu rauemi mata o te boron trioxide me te pāmahana oumu teitei ake e hiahiatia ana hei whakarewa i te borosilicate. Mō tētahi waitohu e whakahaere ana i te 100,000 pounamu ia marama, he mea nui te rerekētanga utu ā-tau, ā, ka kitea tika i te rārangi taha. Mō tētahi waitohu e whakahaere ana i te 1 miriona pounamu ia marama, ko te rerekētanga utu ko te rerekētanga i waenga i tētahi SKU ora me tētahi SKU ka mutu i te tau tuarua. Ko te whakataurite utu e whakapūmauhia ana e te ōhanga awa cullet i whakaputaina e teTe Whare Tākai Karāhe (GPI), e whai ana i te rerekētanga utu o ngā ihirangi hangarua i waenga i ngā whānau karāhe e rua i ia tau. Ko te tauaAnga ture whakapaipai EU 1223/2009e whakahaere ana i te hanganga anō me te tutuki i ngā whakaritenga mō ngā takai mō ngā whānau karāhe e rua i te mākete Pākehā.

Mō te māramatanga whatu, ko te karāhe houra-rima te karāhe mārama ake. Ko te taupū whakaata ko te 1.518, koinei te paerewa mō ngā takai karāhe whakapaipai. Ko te taupū whakaata o te Borosilicate he 1.474, he iti ake te māramatanga whatu, ā, he rerekē te huarahi e whiti ai te mārama i roto i te pounamu. Mō tētahi waitohu ko te māramatanga o te pounamu te kereme hokohoko matua, ko te karāhe houra-rima te karāhe ātaahua ake.

Mō te āheinga hanga ā-mīhini, ka taea te hanga i te raima-houra ki roto i te whānuitanga o ngā āhuahanga me te tere whakaputa teitei ake. He iti ake te ira rewa, he whānui ake te whānuitanga mahi, ā, ka taea te pupuhi, te pēhi, me te pēhi-me-te-pupuhi i te karāhe i runga i ngā mīhini pounamu whakapaipai paerewa. Me whai whānuitanga mahi kuiti ake te borosilicate me te whakamatao whakahaere ake, e whakawhāiti ana i ngā kōwhiringa āhuahanga me te whakaiti i te tere whakaputa. Mō tētahi waitohu me te āhuahanga ritenga, ko te raima-houra te karāhe whai hua ake hei tohu. Ko ngā kōwhiringa āhuahanga pounamu whakapaipai paerewa kua whakarārangihia i raro i teNgā paerewa whakaoti pounamu a te SPI (Society of the Plastics Industry)e whakahuatia ana e te nuinga o ngā toa pokepoke ritenga ina whakaarohia ana te whaihuatanga o te āhuahanga i runga i tētahi SKU hou.

I te taha o te whare putunga me te taha tuku, he mea nui te painga o te houra-raima. Ka tākaihia e mātou ngā pounamu houra-raima ki roto i ngā pakitara-rua paerewa me te maha o ngā wehewehenga o te 12 ki te 24 mō ia pouaka i runga i te āhua o te pounamu, ā, ka tukuna te pouaka i te akomanga uta taraka paerewa. Ka tākaihia e mātou ngā pounamu borosilicate ki roto i te pouaka kotahi engari me te maha o ngā wehewehenga kua whakaitihia mā te 15% hei utu mō te utu pakaru teitei ake. Ko te utu pakaru i te wā e kawe ana e utu ana te kaihoko i te 50 hēneti mō ia pounamu houra-raima, he 80 hēneti ki te 1 tāra mō ia pounamu borosilicate, ā, ko taua rerekētanga mōrearea te mea e whakaarohia ana e mātou ki roto i ngā whakaritenga tākai mō ā mātou tuku kaweake.

Ngā Wāhi e Toa ai te Borosilicate: Te Ātete ki te Wera, te Ātete ki te Waikawa, me te Roa o te Ora

Ko te karāhe borosilicate te whiringa tika mō te whakamahinga ina pēhia te pounamu e te hanganga, e te raina whakakī rānei, ki tua atu i te kaha o te houra-raima. Ko ngā āhuatanga e toru e hanga ana i te borosilicate hei whakaritenga kounga teitei ko te ātete wera, te ātete waikawa, me te roa o te ora.

Ki te ātete ki te wera, ka taea e te borosilicate te ora i te whakakī wera i runga ake i te 80°C, ā, ka taea te whakaweto i te 121°C hei whakaweto. Nā te kaha o te autoclave te take i noho ai te borosilicate hei paerewa rongoā mō ngā whakaritenga werohanga, ā, nā taua kaha anō i waiho ai te borosilicate hei paerewa mō ngā hua tiaki kiri e hiahia ana kia whakakīhia kia kore he matū. Mō tētahi waitohu he kereme "kāore he matū tiaki", ko te whakakīnga kia kore he matū ka tutuki mā te whakaweto i te pounamu kua whakakīhia ki te autoclave, he mea ka taea anake i roto i te borosilicate.

Mō te ātete waikawa, ka mau te borosilicate i te pH o te hanganga puta noa i te awhe pH 2 ki te pH 11, me te kore e taea te ine i te nekehanga i roto i ngā marama 12 i te 40°C. Ko te ātete waikawa te take i noho ai te borosilicate hei paerewa mō ngā hanganga AHA, ngā hanganga waikawa salicylic, me ngā ranunga hinu kakara citral-teitei. Mō tētahi waitohu he kaha pH-tairongo, ko te borosilicate anake te whakatakotoranga ka taea te tiaki.

Mō te roa o te wā e mau ana te borosilicate, ka mau tonu ōna āhuatanga mō te 36 marama te roa o te wā e mau ana, kāore he huringa e taea te ine, ko te houra-rima ia ka whakaatu i te huringa e taea te ine i muri i te 18 marama i te awhe pH 2 ki te pH 4. Ko te roa o te wā e mau ana te borosilicate te paerewa mō te tiaki kiri haumanu e hokona ana mā ngā hongere me te puhoi o te huringa taonga, tae atu ki ngā tari hauora me ngā whare hauora kiri. Mō tētahi waitohu he hongere haumanu, ko te whakatakotoranga borosilicate anake te whakatakotoranga e tautoko ana i te kereme roa o te wā e mau ana.

Ko tā mātou e kite nei i te taha muri-hoko, he māmā ake te tiaki i ngā kereme borosilicate i roto i te amuamu a te kiritaki. Ina whiwhi te waitohu i te amuamu "kua rerekē te tae o te wai", ka taea e mātou te tango i te kōnae puranga whakaputa me te tirotiro i te tiwhikete akomanga hydrolytic, te pH hanganga, me te pāmahana raina whakakī ki te kereme. Mena i tohua e te waitohu te borosilicate, ā, kei roto te puranga whakaputa i te whakapuakitanga HGA 1 a te kaiwhakarato, ka kati te kereme i roto i te whakautu kotahi. Mena i tohua e te waitohu te houra-raima i te pH 3.5, me whai whakamātautau horoi i te pounamu kua whakahokia mai me te rangahau 4-wiki te kereme, koinei te rerekētanga i waenga i te urupare ratonga kiritaki kotahi-taahiraa me te rangahau kounga ōkawa.

Ngā Pātai Auau

He pai te utu mō ngā pounamu whakapaipai i te karāhe borosilicate?
Mō ngā ranunga whakakī-wera i runga ake i te 70 nekehanga Celsius, mō ngā ranunga hinu kakara he nui te ihirangi citral, eugenol rānei, ā, mō ngā matū tiaki kiri he pH kei raro iho i te 4, neke atu rānei i te 9, ka whakahokia mai te utu borosilicate premium o te 30% ki te 60% i runga ake i te houra-rima mā te iti ake o ngā mea i whakakorea i roto i te rārangi whakakī me te roa ake o te oranga. Mō ngā ranunga wai i te pH 5 ki te 8 kua whakakīia i te pāmahana rūma, ko te houra-rima te paerewa, ā, kāore e tika te utu premium.

He aha te rerekētanga tuturu o te ru wera i waenga i te karāhe borosilicate me te karāhe houra-raima?
Ko te karāhe borosilicate me te tauwehenga whānui wera 3.3 x 10^-6/K ka taea te tu atu ki te rerekētanga pāmahana tata ki te 160 nekehanga Celsius i mua i te pakaru i raro i te whakamātautau ru wera paerewa. Ko te karāhe houra-raima me te tauwehenga 9 x 10^-6/K ka taea te tu atu ki te rerekētanga tata ki te 40 nekehanga Celsius. Ko te tikanga mahi mō te raina whakakī ko te taea e te pounamu borosilicate te neke mai i te whakakī wera 90 nekehanga Celsius ki te taiao matao 25 ​​nekehanga Celsius me te kore e pakaru, ko te pounamu houra-raima ia e kore e taea te neke mai i te whakakī wera 60 nekehanga Celsius ki te taiao 20 nekehanga Celsius me te kore he tere whakakorenga e taea te ine.

Ka mimiti te kawakore i te karāhe houra-raima ki roto i ngā hanganga whakapaipai?
Āe, inehia. Ka taea e te karāhe wai-raima HGB 3 hydrolytic te whakanui ake i te pH o te hanganga wai-iti-pūwero mā te 0.3 ki te 0.7 ngā wae pH i roto i ngā marama 12 i te 40 nekehanga Celsius, he nui tēnei hei whakakore i ngā matū hohe pēnei i te niacinamide, i te waikawa salicylic rānei. Kāore te karāhe borosilicate i te akomanga hydrolytic HGA 1 e whakaatu ana i te nekehanga pH inehia i raro i te āhua whakamātautau kotahi. Mō ngā hanganga me ngā matū hohe pH-tairongo, ko te kōwhiringa o

Ka taea te hanga i tētahi pounamu pata 30ml i roto i te borosilicate me te houra-rima?
Ae, ko te whakatakotoranga pounamu hinu kakara porotaka 30ml he matotoru te raro, e hangaia ana i roto i ngā whānau karāhe e rua. He taumaha ake, he utu nui ake hoki te momo borosilicate, engari ko te whakakaha matotoru te raro e hoatu ana ki ngā momo e rua he mahi whakamātautau maturuturu rite tonu. Ko te kōwhiringa i waenga i ngā mea e rua e peia ana e te whakatakotoranga me ngā āhuatanga o te raina whakakī, ehara i te āhua o te pounamu.

Ko tēhea karāhe he pai ake te hangarua?
