I-Alkyl Polyether: Izinto ezisetyenziswa kwiikhemikhali ezininzi ezisetyenziselwa usetyenziso olwahlukeneyo-1
IiNdawo eziPhambili zeSicelo
Kwishishini leekhemikhali, ii-alkyl polyethers zisetyenziswa njengezinto eziluhlaza kwiifoam ze-polyurethane, ii-adhesive, ii-sealants, kunye nee-elastomers. Iifoam ze-polyurethane zisetyenziswa kakhulu kwifenitshala, kwiimatrasi, kwizitulo zeemoto, nakwizinto zokukhusela izakhiwo. Ii-adhesive ze-polyurethane kunye nee-sealants zisetyenziswa ekuhlanganiseni izakhiwo, iimoto kunye nezixhobo ze-elektroniki.
Kwishishini lamayeza, ii-alkyl polyethers zisebenza njengezinto ezincedisayo kunye nezixutyisi kumayeza, nto leyo ephucula uzinzo kunye nokunyibilika kwawo. Zikwasetyenziselwa ukuvelisa ii-defoamers, ii-surfactants, kunye nee-wetting agents, ezisetyenziswa kakhulu kwi-sprays zomlomo, zeempumlo, ii-eye drops, ii-ear drops, kunye nee-shampoos.
Kwimizi-mveliso yelaphu nephepha, ii-alkyl polyethers zisetyenziswa njengezinto ezithambisayo, izinto ezithintela i-static, kunye nezinto ezimanzisa. Ziphucula ukuthamba kunye neempawu ezithintela i-static zelaphu kwaye zonyusa umgangatho wephepha kunye nokusebenza kakuhle kwemveliso ekwenzeni iphepha.
Kwicandelo lesepha kunye neemveliso zokhathalelo lomntu, ii-alkyl polyethers zisetyenziswa njenge-surfactants kunye ne-emulsifiers. Zibonisa ubuchule obuhle bokucoca, ukukhupha igwebu, ukuzinzisa igwebu, ukumanzisa, kunye ne-emulsifying, ezisetyenziswa kakhulu kwiishampu, ekuhlambeni umzimba, kwiisanitizer zezandla, nakwiisepha zokuhlamba impahla.
Ukongeza, ii-alkyl polyethers zisetyenziswa njengee-demulsifiers kunye nee-lubricants kwishishini le-petroleum, kunye nee-coolants kunye nee-lubricants ekucutshungulweni kwesinyithi.
Inkqubo yokuvelisa ii-alkyl polyethers idla ngokuquka unyango lwangaphambi kokunyangwa kwee-initiators kunye nee-catalysts, ii-ring-opening polymerization reactions, kunye namanyathelo okucubungula emva kokusetyenziswa anje ngokungathathi cala, ukufunxa, ukuphelelwa ngamanzi emzimbeni, ukuhluza, kunye nokuhluza.

Isishwankathelo
Ngamafutshane, ii-alkyl polyethers, njengezinto ezisetyenziswa kwiikhemikhali ezininzi, zidlala indima ebalulekileyo kumashishini amaninzi. Aziphuculi nje kuphela ukusebenza kakuhle kwemveliso kunye nomgangatho wayo, kodwa zikwaxhasa uphuhliso lweshishini lanamhlanje. Ngophuhliso oluqhubekayo lwetekhnoloji, amathuba okusetyenziswa kwee-alkyl polyethers aya kuba maninzi nangakumbi.
