Alkyl Polyether: Thepa e Tala ea Lik'hemik'hale e nang le Mesebetsi e Mengata bakeng sa Litšebeliso tse Fapaneng
Masimo a Maholo a Kopo
Indastering ea lik'hemik'hale, li-polyether tsa alkyl li sebelisoa e le thepa e tala bakeng sa li-foam tsa polyurethane, likhomaretsi, li-sealant le li-elastomer. Li-foam tsa polyurethane li sebelisoa haholo ka thepa ea ka tlung, materaseng, litulong tsa likoloi le thepa ea ho thibela moaho. Likhomaretsi le li-sealant tsa polyurethane li sebelisoa ho kopanyeng mehaho, likoloi le lisebelisoa tsa elektroniki.
Indastering ea meriana, li-alkyl polyether li sebetsa e le lintho tse thusang le tse kopanyang meriana, li ntlafatsa botsitso ba tsona le ho qhibiliha ha tsona. Li boetse li sebelisoa ho hlahisa li-defoamers, li-surfactants le lintho tse nosetsang, tse sebelisoang haholo ka ho noa, ka ho fafatsa nko, ka marotholi a mahlo, ka ho rotha litsebe le ka ho li shampoo.
Liindastering tsa masela le pampiri, li-polyether tsa alkyl li sebelisoa e le li-softening, li-antistatic agents, le li-manufacturer tse kolobisang. Li ntlafatsa bonolo le thepa ea antistatic ea masela le ho ntlafatsa boleng ba pampiri le katleho ea tlhahiso ho etseng pampiri.
Makala a sesepa le lihlahisoa tsa tlhokomelo ea botho, li-alkyl polyether li sebelisoa e le li-surfactant le li-emulsifier. Li na le bokhoni bo botle ba ho hloekisa, ho foam, ho tsitsisa foam, ho kolobisa le ho etsa emulsifier, tse sebelisoang haholo ho shampoo, ho hlatsoa 'mele, ho hloekisa matsoho le sesepa sa ho hlatsoa liaparo.
Ho phaella moo, di-polyether tsa alkyl di sebediswa e le di-demulsifier le di-lubricant indastering ya peterole, hammoho le di-coolant le di-lubricant tse sebediswang ha ho sebetswa tshepe.
Ts'ebetso ea tlhahiso ea li-alkyl polyether hangata e kenyelletsa kalafo ea pele ea li-initiator le li-catalyst, liketso tsa polymerization tsa ho bula selikalikoe, le mehato ea kamora ts'ebetso e kang ho se nke lehlakore, ho monya, ho felloa ke metsi 'meleng, ho sefa le ho qhala.

Ka kakaretso
Ka bokhutšoanyane, li-polyether tsa alkyl, e le lisebelisoa tse tala tsa lik'hemik'hale tse sebetsang ka bongata, li bapala karolo ea bohlokoa liindastering tse ngata. Ha li ntlafatse ts'ebetso ea sehlahisoa le boleng feela empa li boetse li tšehetsa nts'etsopele ea indasteri ea sejoale-joale. Ka tsoelo-pele e tsoelang pele ea theknoloji, menyetla ea ts'ebeliso ea li-polyether tsa alkyl e tla ba kholo le ho feta.
