Propylene Glycol Methyl Etha Acetate
Mafotokozedwe Akatundu
Dipropylene glycol amapeza ntchito zambiri monga plasticizer, wapakatikati mu mafakitale mankhwala zimachitikira, monga polima initiator kapena monomer, ndi monga zosungunulira. Kawopsedwe wake wochepa komanso zosungunulira zimapangitsa kukhala chowonjezera choyenera chamafuta onunkhira ndi zinthu zosamalira khungu ndi tsitsi. Ndiwonso chogwiritsidwa ntchito wamba muzamalonda a chifunga chamadzimadzi, chomwe chimagwiritsidwa ntchito m'makina osangalatsa a chifunga.

Kugwiritsa ntchito
| Diluent ndi leveling wothandizira, angagwiritsidwe ntchito inki, utoto nsalu, nsalu zosungunulira mafuta. |
1) Dipropylene glycol ndiye chosungunulira chabwino kwambiri chamafuta ambiri onunkhira komanso zodzikongoletsera. Izi zopangira zimakhala ndi madzi abwino kwambiri, mafuta ndi hydrocarbon co-solubility ndipo zimakhala ndi fungo lochepa, khungu lopweteka pang'ono, kawopsedwe kakang'ono, kugawa yunifolomu kwa ma isomers ndi khalidwe labwino kwambiri.
2) Itha kugwiritsidwa ntchito ngati cholumikizira cholumikizira komanso chonyowetsa pazinthu zambiri zodzikongoletsera. Mu perfumery, dipropylene glycol amagwiritsidwa ntchito kuposa 50%; pomwe m'malo ena, dipropylene glycol imagwiritsidwa ntchito mochepera 10% (w/w). Ntchito zina zapadera za Chemicalbook ndizo: zodzola tsitsi, zotsuka pakhungu (zopaka zoziziritsa kukhosi, ma gels osambira, zochapira thupi ndi zodzola pakhungu) zonunkhiritsa, nkhope, manja ndi zosamalira khungu, zokometsera zosamalira khungu ndi zopaka milomo.
3) Itha kutenganso malo mu unsaturated resins ndi ma resins odzaza. Ma resins omwe amapanga amakhala ndi kufewa kwapamwamba, kukana ming'alu komanso kukana nyengo. (4) Itha kugwiritsidwanso ntchito ngati cellulose acetate; cellulose nitrate; varnish kwa chingamu cha tizilombo; zosungunulira kwa mafuta a castor; ndi plasticizer, fumigant, ndi zotsukira zopangira.
Ubwino
Ubwino wazinthu, kuchuluka kokwanira, kuperekera kogwira mtima, ntchito yabwino kwambiri Imakhala ndi mwayi wopitilira amine wofanana, ethanolamine, chifukwa kuchuluka kwakukulu kungagwiritsidwe ntchito pakuwonongeka komweko. Izi zimathandiza oyenga kutsuka hydrogen sulfide pamlingo wocheperako wozungulira wa amine osagwiritsa ntchito mphamvu zonse.
