xov xwm

newsPolyethylene glycol (PEG) yog cov polymer ntawm ethylene oxide thiab dej. Nws yog cov dawb paraffin flake lossis hmoov ua kom tawv, tsw lossis muaj ntxhiab tsw tsis muaj zog. Nws yog non-toxic, tsis muaj kuab lom, muaj dej solubility zoo, thiab muaj kev sib raug zoo nrog ntau yam ntawm cov organic. Lawv yog cov dav siv hauv tshuaj pleev ib ce, tshuaj, tshuaj fiber ntau, roj hmab, yas, papermaking, xim, electroplating, tshuaj tua kab, hlau ua thiab kev lag luam ua lag luam vim lawv zoo heev lubricity, ya raws, dispersity, adhesives, antistatic tus sawv cev thiab muag muag.
Kev khaws cia thiab kev thauj mus los ntawm POLYETHYLENE glycol (PEG): cov khoom no yog non-toxic thiab non-flammable. Nws yuav tsum thauj cov khoom siv dav dav thiab muab cia rau hauv qhov chaw qhuav. Lub luag haujlwm tseem ceeb: ntsiav tshuaj, tshuaj ntsiav, zaj duab xis txheej, thiav cov ntsiav tshuaj, yeeb tshuaj thiab lwm yam
Lub zog loj cov kua tshuaj PEG (PEG4000 thiab PEG6000) yog qhov muaj txiaj ntsig zoo li cov nplaum rau ua cov ntsiav tshuaj vim qhov ua tau plasticity ntawm PEG thaum npaj thiab nws lub peev xwm los txhim kho cov tshuaj tso tawm hauv cov ntsiav tshuaj. PEG ua rau saum npoo ntawm lub ntsiav tshuaj ci thiab du, tab sis tsis yooj yim puas.
Lub hygroscopicity ntawm PEG yog qhov tsawg dua li ntawm cov tsis tshua muaj molecular hnyav diols thiab tsawg dua li ntawm glycerol, yog li cov hmoov sib xyaw polyethylene glycol tsis rhiab rau cov kev hloov pauv hauv huab cua puag ncig, thiab qhov muag muag thiab yas ntawm cov tshuaj no tseem zoo li qub txawm tias tom qab lub sijhawm ntev cia. Peg tsawg dua qhov sib hloov tsis xws li diethylene glycol lossis triethylene glycol. Cov kua dej ua kua polyethylene glycol (peg) 200-600 tuaj yeem muab kev xaiv dav dav hygroscopicity, tshwj xeeb tshaj yog haum rau cov yas, roj hmab ntxiv, tuaj yeem siv rau kev npaj ntawm tus neeg ua hauj lwm saum npoo, xim thiab number case, tshuaj, tshuaj pleev ib ce, tshuaj ntxuav tes, ntawv txiav txim siab, ntawv, khoom noj kev ntxiv tshuaj, kev ua tawv tsiaj, roj, kev ua ntoo, ceramics, kev ua liaj ua teb, plating, cov khoom siv thaij duab, cov nplaum thiab cov ntim khoom, thiab lwm yam.
