1,2-Propyleneglycol Diacetate Propylene Glycol Diacetate PGDA CAS 623-84-7
Ko te Propylene Glycol Diacetate (PGDA, CAS 623-84-7), e kiia ana ko te 1,2-Propanediol diacetate, he whakarewa diester kohua nui, mārama, kore tae, he pai ki te taiao, he kakara ester ngoikore. Ko te Parakore ≥99.0%. He tere mimiti ngawari, he tino pai te utu mō ngā kapia kiriaku, PU, alkyd me te nitrocellulose. Hei whakakapinga pai mō te cyclohexanone, isophorone, PMA me te DBE, he whānuitia te whakamahinga i roto i ngā paninga motuka, ngā paninga koiri, ngā waituhi kopare PCB, ngā piripiri wai, te horoi tika hiko me te whare hanga hei whakapakeke ester waro. Ka tukuna hei utanga whānui. Te roa o te rokiroki: 12 marama i raro i te rokiroki hiri matao.

1. Taiao rokiroki: Rokirokihia ki roto i tētahi whare putunga hiri, hauhautanga, maroke, ā, he pai te hauhautanga; ko te pāmahana rokiroki e taunakitia ana he ≤ 30℃, ā, me karo i te rā tika.
2. Te rokiroki motuhake: Puritia kia matara atu i ngā mura ahi me ngā pūtake wera pāmahana teitei; kaua e rongoatia ngātahi me ngā waikura kaha, ngā waikawa kaha me ngā kawakore kaha hei ārai i ngā tauhohenga.
3. Ngā whakaritenga mō te takai: Penapena ki roto i ngā oko taketake kua hiritia hei ārai i te mimiti me te urunga mai o te makuku; whakakīia ngā taupoki o te oko kia kore ai e turuturu.
4. Ngā whakaritenga whakarārangi puranga: Whakatakotoria he oko rino/koko kirihou 220kg ki runga i ngā papa, whakarārangihia kia mau kia kore ai e taka; kia tika te ārai wai o te papa o te whare putunga.
5. Te roa o te oranga: 12 marama te roa o te oranga i raro i ngā tikanga rokiroki o runga ake nei mēnā kāore anō kia whakatuwheratia, ā, kāore hoki i pakaru. Whakamahia wawe tonu te hua i muri i te whakatuwheratanga hei whakaiti i te mimiti me te mimiti wai.
