Nws yog tsuas yog siv los ua polyester, polyester Resin, Desiccant, tshuaj tawg, kom siv cov tshuaj tua kab mob, thiab siv tau los ua cov tshuaj tua kab mob rau cellophane, fiber ntau, tawv thiab nplaum. Nws tuaj yeem tsim cov hluavtaws cob cov tsiaj, fiber {2} {{5 {5 {5 {5 {5}, thiab lwm yam. 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.
Thaum ethylene glycol yog siv raws li txias, nws yuav tsum tau sau tseg tias: 1. Nws cov ntsiab lus khov kho uas muaj kev sib haum xeeb ntawm cov ethylene glycol nyob rau cov aqueevous. 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 80-90 degrees Celsius rau lub sijhawm ntev, ethylene glycol yuav xub ua, oxidized rau hauv glycolic acid, uas yog, 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. Yog tsis muaj kev kho mob tsim nyog, ntau dhau ntawm ethylene glycol tuaj yeem ua rau tuag taus. 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.
3. Ethylene glycoles nws tus kheej yog cov tshuaj tiv thaiv yooj yim, tsim cov khoom siv roj polymular yooj yim thiab cov yeeb yaj kiab uas yooj yim heev uas tau yooj yim rau kev teev; Ntxiv rau, ethylene glycole reacts nrog oxygen los tsim cov lw cov nqi ntawm formic acid thiab acetic acid.
