Lub npe: Mono ethylene glycol (meg)
CAS Tsis muaj: 107-21-1
Molecular cov mis: C2h6o2
Mono ethylene glycol yog ib qho tsis muaj kob, kua me me. Nws muaj qhov ruaj khov nyob ntawm chav tsev kub thiab siab, thiab yog soluble hauv dej thiab ntau cov kuab tshuaj muaj organic. Nws cov tshuaj lom neeg ua rau nws muaj ntau yam. Nyob rau hauv tanning thiab kws tshuaj lag luam, nws yog siv los ua cov neeg muaj dej hiav txwv thiab cov kuab tshuaj, feem ntau. Peb tuaj yeem muab cov kev muaj siab siab muaj qib mono ethylene glycol, thiab cov ntaub ntawv ntim cov khoom siv muaj nyob hauv peb hom, 230 kg /kg / IBC thiab 24MT / FLEXBAGAG.

Lwm yam tshwj xeeb thiab cov khoom lag luam ntawm cov khoom tuaj yeem muab raws li yuav tsum tau ua.
Cov Ntawv Thov
Mono ethylene glycol tau siv dav siv raws li cov kuab tshuaj thiab cov khoom siv lub cev, ua kom muaj zog, ua kom muaj zog nrog dej thiab ntau yam ntawm cov emolic kuab tshuaj.
1. Mono ethylene glycol muaj lub cev cov cuab yeej ntawm siab npau npau (197 degree), uas tuaj yeem ncua cov kuab tshuaj tsis zoo thiab zam qhov tsis xws luag los ntawm cov txheej ceev ntawm txheej lossis number case.
- Daim ntawv thov nyob rau hauv txheej kev lag luam: Nws tuaj yeem sib xyaw nrog dej lossis xws li ethanol) los kho lub sijhawm ziab thiab txhim kho cov cuab yeej leveling.
- Daim ntawv thov hauv cov ntawv luam tawm: Nws tuaj yeem siv ua cov ziab so kom tiv thaiv kom tsis txhob muaj lub pob luam ntawv ntawm ib lub tshuab luam ntawv hauv kev thaiv.
2. Mono ethylene glycol molecule muaj ob pawg hydroxyl (-oh), uas yog ib pawg qib polvent. Nws tuaj yeem ua ke nrog cov tshuaj pua pua pua (xws li dyes, resins, kho cellulose, rhuav tshem kev sib cuam tshuam ntawm molecules thiab txhawb lawv cov kev sib cais.
- Ua ntawv thov rau qhov kev lag luam Dow: tuaj yeem rhuav tshem cov kua qaub, thiab lwm yam, txhim kho kev hnav khaub ncaws ntawm cov khaub ncaws daj;
- Daim ntawv thov nyob rau hauv Resin ua: nws tuaj yeem yaj epoxy cob, polyurethane, thiab lwm yam.
Nws yuav tsum tau muab khaws cia cais los ntawm oxidants thiab acids, thiab yuav tsum tsis txhob sib xyaw. Vim tias muaj kev hygroscopicity muaj zog, nws yuav tsum tau muab ntim rau cia cia rau, thiab nitrogen yuav tsum tau siv rau lub sijhawm ntev cia.
