Khoom Taw Qhia thiab Nta

CH2OH 2, uas yog cov ntaub ntawv yooj yim diol yooj yim. Ethylene glycol yog ib qho tsis muaj kob, tsw ntxhiab, kua qab zib nrog cov tshuaj lom tsawg rau tsiaj. Ethylene glycol tuaj yeem ua ob qho tib si soluble nrog dej thiab acetone, tab sis nws solubility hauv kev ua kom cov neeg ua kom muaj kev pab me me. Siv raws li cov kuab tshuaj, tshuaj tiv thaiv thiab hluavtaws polyester cov khoom siv. Cov polymer ntawm ethylene glycol, polyethylene glycol (peg), yog theem hloov catalyst thiab kuj siv hauv cell fusion

kev siv

Mas siv rau kev ua polyester, polyester, polyester Resin, hluav taws xob muaj kuab, tshuaj lom neeg, cov tshuaj tua kab mob qub, roj av, roj av Kev tsim khoom txee, kuj tseem siv tau rau cellophane, fiber ntau, tawv, nplaum ntub tus neeg sawv cev. Nws tuaj yeem tsim cov khoom siv hluavtaws cov tsiaj, cov tsiaj uas yog polyester fiber, lub raj mis hlais tsiaj rau ua cov ntxhia taub dej thiab lwm yam. Kuj tseem tuaj yeem tsim cov alkyd resin, glyoxal, thiab lwm yam, kuj tau siv raws li cov tshuaj tiv thaiv. Ntxiv rau kev siv ua cov tshuaj tiv thaiv rau cov tsheb thauj mus los, feem ntau hu ua cab kuj muaj peev xwm muaj cov cab kuj zoo li cov hws ua kom zoo li dej.
Ethylene glycol ether series khoom siv tau zoo organic, kua roj vanish Nws tuaj yeem siv tau los ua cov ntaub ntawv raw rau cov khoom siv tshuaj lom xws li cov tshuaj tsis muaj tshuaj ntau, cov kua hluav taws xob thiab cov khoom siv hluavtaws hluav taws xob. Raws li cov electrolytes rau electrolytic capacitors, hluav taws xob fiber ntau, thiab cov roj ua kom zoo nkauj hauv desulfurizer raw cov ntaub ntawv.
Ethylene glycol yuav tsum tau sau tseg thaum siv raws li cov cab kuj:
1. Lub sijhawm khov taw tes hloov nrog kev sib haum xeeb ntawm cov huab cua glycol nyob rau cov kua aqueous. Thaum lub siab xav tau qis dua 60%, cov kev ntsuas khov ntawm cov ethylene nce nrog kev nce siab ntawm cov ethylene glycol, thiab viscosity nce nrog kev nce ntawm kev xav tau. Thaum lub siab xav txog 99.9%, nws lub laj thawj khov ua yog vim li cas thiaj li siv tau cov tshuaj tiv thaiv niam ua) tsis tuaj yeem siv ncaj qha, thiab yuav tsum nyiam cov xim ntawm tus neeg siv.
2. Ethylene glycol muaj cov pab pawg hydroxyl, uas yuav yog oxidized rau glycolic acid, uas muaj 2 tus kab mob carboxyl, thaum nws ua haujlwm ntawm 80-90 ℃ ntev. Oxalic acid thiab nws cov khoom siv cuam tshuam ua ntej lub siab nruab nrab hauv nruab nrab, ces lub siab, thiab tom qab ntawd ob lub raum. Ethylene glycol glycol glycolic acid, ua rau mob corrosion thiab to lav ntawm cov khoom siv. Yog li ntawd, nyob rau hauv kev npaj ntawm cov tshuaj antifle, yuav tsum muaj kev khaws cia kom tiv thaiv kev xeb ntawm cov hlau, txhuas thiab tsim ntawm nplai.

Pob Thiab Thauj

B. Cov khoom lag luam no tuaj yeem siv ,, 25kg, 200kg, 1000kgbaerls.
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
