Polyethylene glycol Peg 200 CAS NO.25322-68-3
Khoom Description
- PEG yog lub npe luv ntawm cov lus Askiv lub npe polyethylene glycol. PEG 200 yog non-toxic, non-irritating, muaj dej solubility zoo, thiab muaj zoo compatibility nrog ntau cov organic Cheebtsam. Lawv muaj lubricity zoo, noo noo tuav, dispersibility, adhesives, antistatic agents thiab softeners, thiab yog siv nyob rau hauv tshuaj pleev ib ce, tshuaj, tshuaj fibers, roj hmab, yas, ntawv, xim, electroplating, tshuaj tua kab, hlau ua thiab zaub mov, thiab lwm yam. . Muaj kev siv dav heev hauv kev lag luam.
- PEG-200 tuaj yeem siv los ua qhov nruab nrab rau cov organic synthesis thiab cov khoom siv cua sov nrog cov kev xav tau siab dua. Nws tuaj yeem siv ua cov tshuaj humectant, inorganic ntsev solubilizer, thiab viscosity regulator hauv kev lag luam tshuaj txhua hnub; nws tuaj yeem siv los ua softener thiab antistatic tus neeg sawv cev hauv kev lag luam textile. ; Siv los ua tus neeg sawv cev ntub dej hauv kev lag luam papermaking thiab tshuaj tua kab. Raws li hlau ua pwm tus neeg saib xyuas, hlau kos duab, stamping los yog tsim cov roj nplua nyeem thiab txiav cov kua, sib tsoo txias lubricating polishing tus neeg saib xyuas, tus neeg sawv cev vuam, thiab lwm yam .; siv los ua cov roj nplua nyeem hauv daim ntawv kev lag luam, thiab lwm yam, thiab kuj tseem siv los ua cov nplaum kub yaj los ua kom muaj peev xwm rov qab sai sai. PEG-200 yog non-toxic, non-flammable, thiab khaws cia thiab thauj raws li cov tshuaj siv dav dav. Khaws rau hauv qhov chaw qhuav thiab ventilated.

Daim ntawv thov
- Polyethylene glycol series cov khoom siv tuaj yeem siv rau hauv cov tshuaj.Polyethylene glycol nrog qhov hnyav molecular kuj tuaj yeem siv los ua cov kuab tshuaj, cosolvent, dispersant, O / W hom emulsifier thiab stabilizer, siv los ua cement suspensions, emulsions, txhaj tshuaj, thiab lwm yam. thiab kuj siv los ua dej-soluble ointment puag thiab suppository puag, khoom waxy polyethylene glycol nrog cov txheeb ze molecular hnyav feem ntau yog siv los ua kom cov viscosity thiab solidification ntawm cov kua dej uas tsis muaj molecular PEG, thiab los them rau lwm yam tshuaj; rau cov tshuaj uas tsis yooj yim yaj nyob rau hauv dej, cov khoom no yuav siv tau raws li ib tug khoom dispersion cab kuj, nyob rau hauv thiaj li yuav ua kom tiav lub hom phiaj ntawm cov khoom dispersion.
- Polyethylene glycol series cov khoom tuaj yeem siv los ua cov ntaub ntawv raw rau ester surfactants.
- Nws tuaj yeem siv los ua qhov nruab nrab rau cov organic synthesis thiab cov khoom siv hluav taws xob nrog cov kev xav tau siab dua. Nws tuaj yeem siv ua cov tshuaj humectant, inorganic ntsev solubilizer thiab viscosity regulator hauv kev lag luam tshuaj txhua hnub; ua softener thiab antistatic tus neeg sawv cev hauv kev lag luam textile; Siv los ua tus neeg sawv cev ntub dej hauv kev lag luam papermaking thiab tshuaj tua kab.
