1,2-Propylene Glycol CAS NO.57-55-6
Sharaxaada Alaabta
- 1,2 Propylene glycol oo ah dhexdhexaad difenoconazole bakteeriyada iyo walxo muhiim ah oo ceeriin ah oo loogu talagalay polyesterka aan saturated lahayn, resin epoxy, iyo poliurethane. Qadarka dhinacan ayaa ka dhigan qiyaastii 45% wadarta isticmaalka 1,2 propylene glycol. Ester-kan polyester-ka ah ee aan dheregsanayn ayaa si weyn loogu isticmaalaa daahaarka dusha sare iyo bacaha la xoojiyay. 1,2 Propylene glycol waxay leedahay viscosity wanaagsan iyo hygroscopicity, oo aan sun ahayn, sidaas darteed waxaa si ballaaran loo isticmaalaa sida nuujinta qoyaanka, antifreeze, saliidaha iyo dareeraha cuntada, daawada iyo warshadaha qurxinta. Warshadaha cuntada, waxa inta badan loo isticmaalaa emulsifier-cunto ahaan; Isla markaana waa dareere aad u fiican oo loogu talagalay xawaashyada iyo midabada.
- Habka soo saarista ee 1,2 propylene glycol waxaa iska leh qaybta farsamada ee kala-soocidda kiimikada. Habkani waxa uu ka faa'iidaysanayaa sifooyinka in milixyada asiidhka macdanta ay si fudud u dhalaaliyaan, halka milixyada aashitada organic ee maraq halsano propylene glycol aanay fududayn in la miirto. Qadar ku habboon oo ah aashitada inorganic ayaa lagu daraa maraq halsano propylene glycol si loogu beddelo cusbada acids organic ee maraq halsano leh acids organic. milixda aashitada macdanta ee u dhiganta ayaa la abuuraa; maraq halsano ah ayaa xooga saaraya, si ay milix acid macdanta crystallizes, oo laga soocay maraq halsano; Maraq halsano ah oo xoog leh ayaa noqda propylene glycol, acid succinic, lactic acid, acetic acid, glycerol iyo 2,3-butane Isku dar ah khamriga, nadiifinta vacuum ee isku dhafka ah si loo helo alaabta qayb kasta. Warshadaha dawooyinka, propylene glycol waxaa inta badan loo isticmaalaa sida dareere, jilciya iyo udgoon loogu talagalay soo saarista boomaatada iyo boomaatada kala duwan. Sababtoo ah waafaqid wanaagsan oo leh dhir udgoon oo kala duwan, waxa kale oo loo isticmaalaa sida dareere iyo jilciye loogu talagalay qurxinta.Propylene glycol sidoo kale waxaa loo isticmaalaa qoyaan tubaakada, wakiilka antifungal, qalabka wax lagu sameeyo ee saliidda saliidda iyo dareeraha qalin calaamadinta cuntada. Xalka aqueous ee propylene glycol waa ka hortag waxtar leh.

Codsiga
- Sida dareere ah, waxay milmi kartaa cuntada lagu daro ee aan ku milmi karin biyaha sida kuwa ilaaliya, midabada, antioxidants, iwm, ka dibna ku darso cuntada; waxay leedahay hygroscopicity xoog leh, waxayna leedahay saameyn huurka iyo ka-hortagga-barafka cuntada.
- Sida side daroogada iyo wakiilka daroogada granular. Waxaa loo isticmaali karaa sida huctant, jilcisa, dareere, iwm.
- Warshadaha tubaakada, waxa loo isticmaali karaa sida dhadhanka tubaakada, qoyaanka tubaakada, ilaalinta, iwm.
- Warshadaha cuntada, waxa loo isticmaalaa sida dareere loogu talagalay dhadhanka, midabaynta cuntada, jilciyaasha baakadaha cuntada, iyo walxaha cuntada lidka ku ah.
