Polyols: Jami ma ki tiyo kwede i yoo mapol pi tic i kampuni ki luwil
Kabedo ma pire tek me tic kwede
I tic me yubu jami ma ki lwongo ni chemical, polyols obedo jami ma ki tiyo kwede me yubu jami ma pek ne dwong calo polyesters, polyethers, ki polyurethanes. ma calo, ethylene glycol ki tiyo kwede me yubu polyethylene terephthalate (PET), ma pol kare ki tiyo kwede i cupa ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki yubu ki jami ma ki lwongo ni plastic. Polyethylene glycol (PEG) ki tiyo kwede me yubu jami ma pat pat ma weko kom bedo maleng ki moo. Medo ikom meno, polyols twero tic calo gin ma juku jami makwo ma pat pat, ma medo tic pa jami makwo.
I tic me yubu yadi, polyols ki tiyo kwede ma calo jami ma weko pii bedo maleng, jami ma weko pii bedo maleng, ki jami ma weko pii bedo maleng. Me labolle, propylene glycol ki glycerol pol kare ki tiyo kwede me yubu yat, pii ma ki mato, ki moo me medo rwom me tic pa yat. Medo ikom meno, polyols ki tiyo kwede me yubu yadi ma ki twero gonyo ne, ma doro rwom me gonyo yadi ni.
I lok ma mako dek, polyols ki tiiyo kwede ma calo jami ma miyo cam bedo mit, jami ma miyo pii bedo maleng, ki jami ma miyo jami bedo maleng. Me labolle, glycerol ki polyethylene glycol ki tiyo kwede me yubu jami acama, jami ma ki yubu ki mugati, ki jami amata, ma miiyo mit ki gwoko pii. Medo ikom meno, polyols ki tiyo kwede me loko rwom ki kit ma cam winye kwede i dog, medo kare me gwoko ne.
I dul ma yubu jami me deyo ki gwoko del kom, polyols ki tiyo kwede ma calo humectants ki emulsifiers. ma calo, propylene glycol ki glycerol twero mako pii, ma miyo del kom ki yer bedo ma pii. Medo ikom meno, polyols ki tiyo kwede me yubu jami ma gengo ceng, jami ma ki lwoko wic, ki jami ma miyo kom bedo maleng, ma miiyo jami ma miyo kom bedo maleng ki moo.
I tic me yubu jami ma ki yubu ki plastik, polyols ki tiyo kwede calo jami ma weko plastik bedo yot ki tic kwede. Me labolle, glycerol ki polyethylene glycol ki tiyo kwede calo jami ma weko polyvinyl chloride (PVC) bedo maber, ma weko bedo yot ki rii. Medo ikom meno, polyols ki tiyo kwede me yubu jami ma ki yubu ki jami ma kwo, ma dwoko piny peko ma twero balo kwo pa dano.
I tic me yubu bongo ki inks, polyols ki tiyo kwede calo jami ma weko jami bedo maber ki jami ma weko jami bedo maber. Gitwero juku jami ma pat pat ma ki lwongo ni resins ki pigments, ma miyo jami maber me yubu filim. Me labolle, polyethylene glycol ki tiyo kwede me yubu jami ma ki keto i pii ki ink, ma miiyo kony ma pe balo kwo pa dano ki ma tiyo maber.
