Alkyl Polyether: A phunphun in hmannak caah hman khawhmi chemical thilri
A Biapimi Hmannak Hmun
Chemical industry ah, alkyl polyethers cu polyurethane foams, adhesives, sealants, le elastomers caah thilri ah hman a si. Polyurethane foams cu innchung thilri, ihkhun, mawtaw tthutdan le inn lumternak thilri ah tampi hman a si. Polyurethane hrenhnak le kharnak hna cu inn, mawtaw le electronic thilri pawl fonhnak ah hman an si.
Sii lei riantuannak ah, alkyl polyethers cu sii ah bawmtu le cawhmi ah rian an ttuan, an fekmi le an cawh khawhnak a ṭhanchoter. Cun, hnar hlonhnak, surfactants, le wetting agents sernak caah hman an si, kaa, hnar thletnak, mit sii, hnakhaw sii, le sam ttawlnak ah tam deuh in hman a si.
Thilpuan le cauk sernak ah, alkyl polyethers cu nemtertu, a lumtertu le a lumtertu ah hman a si. Puan hna i nemnak le antistatic thilri hna kha an tthanchoter i cauk sernak ah cauk tthatnak le chuah khawhnak tthatnak kha an tthanchoter.
Thil sawhnak le pumpak zohkhenhnak thilri lei ah, alkyl polyethers cu surfactants le emulsifiers ah hman a si. Thianhhlimhnak, hnimhnak, hnipuan ttha tein chiah khawhnak, hnimh khawhnak le cawh khawhnak an langhter, shampoo, pum tawlnak, kut thianhnak le thil sawhnak ah tampi hman a si.
Cun, alkyl polyethers cu petroleum industry ah demulsifiers le lubricants ah hman a si, cun thir sernak ah coolant le lubricants ah hman a si.
Alkyl polyethers sernak kalning ah a tlangpi in a thawktu le a thlentu hna kha hlan tein thlopnak, ring-onnak polymerization reactions, le a hnu ah thlennak step hna cu neutralization, adsorption, ti tlawmternak, filteration, le distillation tibantuk hna aa tel.
