Teitei-Parakore Butyl Acetate: Te Whakarewa Ahumahi
Whakaahuatanga
| Kāwai Taonga | Whakatakotoranga |
| Ngā Mōhiohio Taketake | Tātai Matū: C₆H₁₂O₂CASTau: 123-86-4 Kupu Taurite: n-Butyl Acetate Āhua: Wai mārama kore tae me te kakara hua motuhake |
| Ngā Āhuatanga Ā-tinana | Te Pūnga Kohua: 126.1°CTe Pūwāhi Rewa: -77.9°C Kiato (20°C): 0.88 karamu/cm³ Pūwāhi Mura (Kapu Katia): 22°C (Mura, Kāwai 3) Wairewatanga: He wairewa paku ki te wai (~0.7 g/100 mL i te 20°C); ka taea te whakaranu ki ngā waipiro, ngā etera, ngā warowaihā Pēhanga Kohu (20°C): 1.3 kPa Taupū Whakaata (20°C): 1.394 |
| Ngā Āhuatanga Matū | Pūmautanga: Pūmau i raro i te pāmahana me te pēhanga noa Kāore e hototahi: Ngā matū whakahāora kaha, ngā waikawa, ngā turanga Waikawa: Ka tauhohe i roto i ngā āhuatanga waikawa/kawakore hei hanga i te butanol me te waikawa aceticMura: Ka puta he ranunga pahū i te kohu me te hau (Tepe Pahū: 1.4%–8.0% vol.) |
| Ngā Āhuatanga Matua | Paitini: He iti te paitini; he ngawari te riri ki ngā kanohi me te ara manawaTe Āhuareka: Taurite (he pai mō te whakamaroke taurite i roto i ngā whakatakotoranga) |
Ko te Butyl Acetate (CAS 123-86-4) he whakarewa ester aliphatic tino whai hua, he takawaenga matū nui hoki, e rongonui ana mō tōna taurite o te piki me te heke, tōna kaha ki te utu, me te hototahitanga pai ki te whānuitanga o ngā kapia me ngā polymer. Hei rauemi maha-mahi, he wāhanga matua o te hanganga e whakarato ana i te mahi pumau me te tutuki i ngā paerewa kounga pakari o te hanga me te tukatuka ahumahi hou.
He whānuitia te whakamahinga puta noa i ngā ahumahi o te ao, ko te mahi matua he whakarewa kounga teitei mō ngā paninga motuka, ngā whakaotinga rakau, me ngā waituhi tā gravure, kia maeneene ai te hanganga kiriata me te tere maroke pai; he takawaenga nui hoki mō te hanga kirihou, ngā matū kakara me te kakara, me ngā mea tāpiri rongoā. Ka tautokohia anō hoki e ēnei tono ngā rāngai matua tae atu ki te hanga taonga, te tānga takai, te hanga whakapaipai, me te hanga matū motuhake.
He whānuitanga o ngā kōwhiringa taumata (tohu ahumahi, tohu parakore teitei, me te tohu kai) kei roto i tā mātou hua butyl acetate hei whakatutuki i ngā momo whakamahinga, me ngā tikanga whakahaere kounga tino pakari e whakarite ana i te iti o te wai me te iti o ngā poke mō ngā hua hanganga pumau. Ka oati mātou ki te tuku pono i te nuinga me te iti o te puranga, ngā tuhinga tutukitanga mō ngā taonga morearea katoa (tae atu ki te MSDS, ngā tiwhikete kaipuke UN, me te rēhitatanga REACH), me ngā otinga whakahaere ritenga kua arotauhia mō te kawe wai mura. Hei tāpiri, ka tukuna e tā mātou tīma hangarau motuhake te tautoko takitahi—pēnei i te whakamātautau hototahi hanganga me ngā taunakitanga rokiroki haumaru—hei whakarei ake i te pai o tō whakaputanga me te haumaru mahi.

Te tākai o te PERCHLOROETHYLENE
I roto i te pūtu kirihou kupenga 180kg.
Rokiroki: Rokirokihia ki roto i tētahi whare putunga hauhautanga, maroke, ā, he hauhautanga hoki; me noho motuhake mai i ngā matū whakahāora, ngā waikawa me ngā kawakore (tawhiti wehe ≥ 5 mita). Kāore e whakaaetia te rokiroki whakauru.
