Dab tsi yog siv ntawm ethylene glycolol?

Nws yog tsuas yog siv los ua polyester, polyester, polyester, yas, yas, fiber ntau, tshuaj pleev ib ce thiab cov khoom tawg.
Nws kuj tseem siv tau los ua cov kuab tshuaj rau dyes, inks, los npaj cov tshuaj tiv thaiv lub cav, thiab kuj tseem tuaj yeem siv ua cov tshuaj tiv thaiv kab mob cellophane, fiber ntau, thiab cov nplaum.
Nws tuaj yeem tsim cov hluavtaws cob cov tsiaj, fiber {{0 e} Cov fiber ntau tus tsiaj rau kev ua kom cov pob zeb roj av, thiab lwm yam, thiab tseem siv los ua cov antiflewen tus neeg sawv cev.
Ntxiv rau kev siv los ua cov tshuaj antifrowerised tus neeg sawv cev rau lub tsheb thauj mus los, feem ntau hu ua txias, thiab kuj tuaj yeem siv ua dej ua kom zoo li dej. Thaum ethylene glycol yog siv raws li txias, nws yuav tsum tau sau tseg tias:
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 ntau dua 60%, nws qhov kev xav tau nce, thiab cov viscrowe yuav nce ntxiv nrog kev nce siab. Thaum lub siab xav txog 99.9%, nws cov lus taw taw khov nce rau -13.2 degree. Qhov no yog ib qho laj thawj tseem ceeb vim li cas thiaj muaj cov tshuaj tiv thaiv niam ua ke (tshuaj tiv thaiv niam niam txiv hli) tsis tuaj yeem siv ncaj qha, thiab nws yuav tsum nyiam cov neeg siv khoom.
2. Ethylene Glycol muaj cov pab pawg hydroxyl. Thaum ua haujlwm ntawm 80 degrees Celsius- 90 qib ua ntej yog oxidized rau hauv glycolic acid, oxalic acid (oxalic acid), uas muaj 2 carboxyl pawg. Oxalic acid thiab nws cov khoom lag luam 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 cov khoom thiab ua rau nws xau. Yog li ntawd, hauv kev npaj cov tshuaj tua kab mob, cov tshuaj tiv thaiv kev yuav tsum muaj nrog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau xeb ntawm cov hlau thiab txhuas thiab qhov tsim ntawm nplai.
Ethylene glycol methyl ether cov khoom lag luam yog high - qib cov kuab tshuaj organic nrog kev ua tau zoo heev. Lawv tau siv los ua cov kuab tshuaj thiab cov huv rau cov neeg sawv cev, luam yeeb, thiab lwm yam, thiab nws tsis tuaj yeem siv dav hlau.
Nws tuaj yeem raug siv los ua kev sib xyaw ua ke rau kev tsim cov tshuaj tua kab thiab kws tshuaj, thiab yog ib qho nruab nrab rau cov fungicSamethylenChlor thiab Benomyl. Nws tseem yog cov khoom siv raw rau cov khoom lag luam xws li cov kua hluavtaws; Tawv thiab tshuaj lom Fiber dyes, thiab lwm yam.
Ntxiv cov echerylene glycol rau cov kua hauv cov dej hauv cov kua rau cov kua hauv cov roj {}}} bas based cov roj hmab thiab cov roj av corroding hauv lub kaw lus; Dej - based hydraulic kua nrog ethylene hydraulic kua siv siv nyob rau hauv cov dav hlau thiab tsheb thiab siab} kub moulding machine.
Nws yog siv los ua cov khoom siv textile, ib qho khoom siv raw rau hluavtis ua kua, thiab tus desulfurizer hauv chiv thiab roj ntxiv.
Nws yog siv los ua kev tshuaj ntsuam tawm tsam, ib qho nruab nrab Chromatographic reagent, thiab lub capacitorcetic nruab nrab.
