Kev siv ntawm MEG
Kev siv:
1. Siv tau los ua polyester, polyester, polyester resin, hygroscopic tus neeg sawv cev, tshuab yas, surfactant, hluavtaws fiber, tshuaj pleev ib ce.
2. Nws tuaj yeem siv los ua tus neeg sawv cev ntub dej rau cellophane, fiber ntau, tawv, thiab cov nplaum.
3. Nws tuaj yeem tsim cov khoom siv hluavtaws cov tsiaj, fiber ntau cov tsiaj yog polyester fiber, lub raj mis flake qib lawb tsiaj yog siv los ua cov ntxhia taub dej, thiab lwm yam.
4. Nws tuaj yeem tsim cov alkyd resin, glyoxal, thiab lwm yam, thiab tseem siv raws li cov tshuaj tiv thaiv.
Them sai sai rau thaum siv ethylene glycol raws li ib tug tub yees tub yees, koj yuav tsum:
Nws qhov tseeb taw tes hloov 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%, raws li kev xav ntawm cov ethylene glycol nce, qhov khov taw tes hloov. Raws li kev xav tau nce, nws qhov chaw khov khov sab zoo li sawv, thiab viscosity kuj nce raws li kev xav tau. Thaum lub siab xav txog 99.9%, nws cov lus taw taw qhia khov nce rau {}}. 2 degree.
Ethylene glycol muaj cov pab pawg hydroxyl. Thaum ua haujlwm ntawm 80 degrees Celsius {1}} degrees Celsius rau lub sijhawm ntev, uas yog oxalic acid, uas yog, oxalic acid), uas muaj 2 carboxyl pawg. Oxalic acid thiab nws cov khoom lag luam cuam tshuam rau nruab nrab lub paj hlwb ua ntej, ces lub siab, thiab tom qab ntawd ob lub raum. Ethylene glycol oxalic acid, uas ua rau corrosion rau cov khoom siv thiab ua rau nws xau. Yog li ntawd, nyob rau hauv lub antifroze, tseem yuav tsum muaj cov tshuaj tiv thaiv kom tiv thaiv kev xeb ntawm cov hlau thiab txhuas thiab qhov tsim ntawm nplai.
