Ntxiv rau kev siv los ua cov tshuaj tiv thaiv rau cov tsheb thauj mus los, nws tseem siv rau kev thauj mus los ntawm kev lag luam txias, feem ntau hu ua txias. Nyob rau tib lub sijhawm, nws kuj tseem siv tau ua cov neeg sawv cev ua kom zoo li dej. Thaum ethylene glycol yog siv raws li txias, cov hauv qab no yuav tsum tau sau tseg:
1. Nws lub ntsiab Taw qhia kom khov hloov pauv nrog kev sib haum xeeb ntawm ethylene glycol nyob rau hauv cov kua aqueous. Thaum lub siab zoo nyob hauv qab 60%, qhov khov taw tes txo raws li kev pom zoo ntawm cov ethylene glycol nyob rau hauv aqueous kev daws teeb meem. Txawm li cas los xij, tom qab cov siab tshaj plaws siab dua 60%, raws li kev pom zoo ntawm Glycole nce, thiab cov viscosity kuj nce nrog kev xav tau. Thaum lub siab xav txog 99.9%, nws qhov kev xav khov ua laj thawj vim li cas thiaj li haus cawv niam (thiab nws yuav tsum nyiam cov neeg siv khoom.
2. Ethylene Glycol muaj cov pab pawg hydroxyl. Thaum ua haujlwm ntawm 80 degrees Celsius {2}}} oxidized rau hauv glycoled rau hauv glycolic acid, oxalic acid (oxalic acid), uas muaj 2 carboxyl pawg. Oxalic acid thiab nws cov byproducts yuav ua ntej cuam tshuam rau hauv nruab nrab lub paj hlwb, ces lub siab, thiab tom qab ntawd ob lub raum. Ethylene glycol oxalic acid corrodes thiab ua rau nws xau. Yog li ntawd, hauv kev npaj cov tshuaj tiv thaiv, cov tshuaj tiv thaiv kom muaj los tiv thaiv corrosion ntawm cov hlau thiab txhuas thiab qhov tsim ntawm nplai.
Ethylene glyyl ether cov khoom lag luam yog high-clad laminates, luam ntawv rau luam yeeb yaj kiab zoo, luam tawm kom tsim cov tshuaj pleev xim zoo nkauj, yog li nws tsis tuaj yeem siv dav ua ib qho kuab tshuaj.
Nws tuaj yeem raug siv los ua kev sib xyaw ua ke rau kev tsim cov tshuaj tua kab thiab kws tshuaj, thiab yog nruab nrab rau cov fungicSamethylenetracline thiab benomyl. Nws tseem yog cov khoom siv raw rau cov roj hluavtaws thiab lwm cov khoom siv tshuaj lom neeg; Tawv thiab tshuaj lom Fiber dyes, thiab lwm yam.
Ntxiv cov echerylene glycol rau cov kua dej rau cov kua dej txhua zaus tuaj yeem tiv thaiv cov roj-based hydraulic los ntawm corrooring roj hmab hauv lub kaw lus; Dej-based cov kua dej nrog ethylene glycol raws li lub ntsiab tivthaiv yog tsis muaj nplaim taws cov kua dej tsis zoo siv hauv cov dav hlau, tsheb thiab kub moulding machine.
Nws yog siv los ua cov tshuaj pleev xim rau hluav taws xob, cov khoom siv ua kom zoo nkauj, thiab cov khoom siv raw rau cov neeg saib xyuas kev ua haujlwm ntawm cov chiv thiab roj ntxiv.
