Glycol Diethyl ether acetate hmoov
Product Description
MEA tuaj yeem tsim los ntawm kev ua haujlwm ammonia / dej nrog ethylene oxide ntawm qhov siab ntawm 50-70 bar kom ammonia nyob rau hauv cov kua theem. Cov txheej txheem yog exothermic thiab tsis xav tau ib qho catalyst. Qhov piv ntawm ammonia thiab ethylene oxide plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov sib xyaw ntawm qhov sib xyaw ua ke. Yog hais tias ammonia reacts nrog ib tug mole ntawm ethylene oxide, monoethanolamine yog tsim, nrog ob molecules ntawm ethylene oxide, diethanolamine yog tsim whereas nrog peb moles ntawm ethylene oxide triethanolamine yog tsim. Tom qab cov tshuaj tiv thaiv, lub distillation ntawm qhov sib tov yog nqa tawm ua ntej kom tshem tawm ntau tshaj ammonia thiab dej. Tom qab ntawd cov amines raug cais los ntawm kev teeb tsa peb-kauj ruam distillation.
Monoethanolamine yog siv los ua chemical reagents, tshuaj tua kab, tshuaj, kuab tshuaj, dye intermediates, roj hmab accelerators, corrosion inhibitors thiab surfactants, thiab lwm yam. Nws kuj yog siv los ua kua qaub gas absorbents, emulsifiers, plasticizers, roj hmab vulcanizing agents, printing thiab dyeing Whitening tus neeg saib xyuas, ntaub. anti-moth agent, thiab lwm yam. Nws kuj tseem siv tau los ua cov yas yas, vulcanizing tus neeg sawv cev, accelerator thiab foaming tus neeg sawv cev rau cov khoom siv hluavtaws thiab roj hmab, nrog rau cov khoom nruab nrab rau tshuaj tua kab, tshuaj thiab dyes. Nws tseem yog cov khoom siv raw rau cov khoom siv hluavtaws, emulsifiers rau cov tshuaj pleev ib ce, thiab lwm yam. Textile kev lag luam ua luam ntawv thiab dyeing brightener, antistatic agent, anti-moth agent, detergent. Nws kuj tseem siv tau los ua carbon dioxide absorber, number case additive, thiab roj av additive.

Daim ntawv thov
| Siv raws li hnyav, nrog rau lwm cov tebchaw siv los ua tawv nplaum, xim stripping tus neeg saib xyuas, hlau kub plating corrosion resistant txheej, thiab lwm yam. |
Hauv cov tshuaj formulations, MEA yog siv feem ntau rau buffering los yog npaj ntawm emulsions. MEA tuaj yeem siv los ua pH regulator hauv tshuaj pleev ib ce.
Nws yog ib qho kev txhaj tshuaj sclerosant raws li kev xaiv kho mob ntawm cov tsos mob hemorrhoids. 2-5 ml ntawm ethanolamine oleate tuaj yeem txhaj rau hauv cov mucosa saum toj no cov hemorrhoids kom ua rau mob rwj thiab mucosal fixation yog li tiv thaiv hemorrhoids los ntawm nqis tawm ntawm qhov quav.
Nws tseem yog ib qho khoom siv hauv kev ntxuav cov kua dej rau lub tsheb cua.
Qhov zoo
Cov khoom lag luam zoo, kom muaj nuj nqis txaus, kev xa khoom zoo, kev pabcuam zoo Nws muaj qhov zoo dua li cov amine zoo sib xws, ethanolamine, nyob rau hauv qhov siab dua yuav siv tau rau tib lub peev xwm corrosion. Qhov no tso cai rau cov refiners los txhuam hydrogen sulfide ntawm qis dua amine tus nqi nrog tsawg zog siv tag nrho.
