Polyols: Riantuannak le Cawtu Hmannak caah Thilri phunphun
A Biapimi Hmannak Hmun
Chemical industry ah, polyols cu polyesters, polyethers, le polyurethanes tibantuk a ritmi thilri sernak caah a biapi tukmi thilri an si. Tahchunhnak ah, ethylene glycol cu polyethylene terephthalate (PET) sernak caah hman a si, plastic thawl le hri ah tam deuh in hman a si. Polyethylene glycol (PEG) cu surfactants le lubricants phunphun sernak caah hman a si. Cun, polyols nih hin organic compound phunphun a thlet khawh, cu nih cun thlennak tthatnak a karhter.
Sii lei riantuannak ah, polyols cu thlennak, plasticizer le humectant ah tampi hman a si. Tahchunhnak ah, propylene glycol le glycerol cu sii a tthawnnak le a fekmi a tthanchotertu ding caah sii chunhnak, kaa chung ti, le chiti sernak ah hman tawnmi an si. Cun, polyols cu control-release sii sernak caah hman khawh a si, sii chuahnak rate kha a uk khawh.
Rawl sernak ah, polyols cu a thlumtertu, a lumtertu le a thlumtertu ah hman a si. Tahchunhnak ah, glycerol le polyethylene glycol cu changreu, changreu kio mi le dinmi thilri sernak ah hman khawh a si, a thlum le a lum lonak a pek. Cun, polyols cu rawl a thlum le a kaa a thlum ning remh khawhnak caah hman khawh a si, cu nih cun a chiah khawhnak caan sauhter khawh a si.
Hmunhma le vun zohkhenhnak lei ah, polyols cu humectants le emulsifiers ah tampi hman a si. Tahchunhnak ah, propylene glycol le glycerol nih ti kha an lak khawh, vun le sam kha ti a tlawmter. Cun, polyols cu ni khamnak sii, sam ttawlnak sii, le sam vun thlennak sii sernak ah hman khawh a si, a lumtertu le a hnihtertu thil a pek.
Plastic industry ah, polyols cu plastics pawl an nemnak le an hman khawhnak ding caah plasticizer ah an hman. Tahchunhnak ah, glycerol le polyethylene glycol cu polyvinyl chloride (PVC) caah plasticizer ah hman khawh a si, a nemnak le a fekmi a tthanchoter. Cun, polyols cu a rawk khomi plastic sernak caah hman khawh a si, pawngkam hnahnawhnak a zorter.
Coating le ink industry ah, polyols cu solvents le emulsifiers ah hman an si. Resins le pigment phunphun an cawh khawh hna, cu nih cun zukcawl sernak ttha a chuahter. Tahchunhnak ah, polyethylene glycol cu ti-hram bunhmi thilthuam le catlap sernak caah hman khawh a si, pawngkam he aa remmi le ttha tein a ttha mi a phichuak a pek.
