I-Alkyl Polyether: I-Multi-Purpose Chemical Raw Material Ezisetjenziswa Ezihlukahlukeneko
Iindawo ezikulu zokusebenza
Ebubulweni lamakhemikhali, ama-alkyl polyethers asetjenziswa njengezinto ezisetjenziswako zokwenza amagwebu we-polyurethane, ama-adhesives, ama-sealants, nama-elastomers. Amagwebu we-polyurethane asetjenziswa khulu efenitjhara, emamatiresini, eenhlalweni zeenkoloyi, kanye nezinto zokuvikela izakhiwo. Iinamatheli ze-polyurethane kanye nama-sealant zisetjenziswa ekuhlanganiseni izakhiwo, iinkoloyi, kanye namadivayisi we-elekthronikhi.
Ebubulweni lemithi, ama-alkyl polyethers asebenza njengezinto ezisizako kanye nama-emulsifiers emithini, okwenza bona kube nokuzinza nokuncibilika kwawo. Zisetjenziselwa nokwenza ama-foamers, ama-surfactants, kanye nama-wetting agents, asetjenziswa khulu emlonyeni, emakhaleni, emathonsini wamehlo, amathonsi weendlebe, kanye namatjhampu.
Ebubulweni beendwangu namaphepha, ama-alkyl polyethers asetjenziswa njengezinto ezithambisako, izinto ezilwisana nokutjhinga, kanye nezinto ezimanzisako. Zithuthukisa ukuthamba kanye nezakhiwo zokulwisana namatjhila begodu zithuthukisa ikhwalithi yamaphepha nokusebenza kuhle kokukhiqiza ekwenzeni amaphepha.
Emkhakheni wokuhlanza nemikhiqizo yokutlhogomela umuntu, ama-alkyl polyethers asetjenziswa njenge-surfactants kanye nama-emulsifiers. Zitjengisa ukuhlanza okuhle, ukukhipha amagwebu, ukuzinza kwegwebu, ukuthambisa, nokuhlanganisa, zisetjenziswa khulu emashampuni, ekuhlanzeni umzimba, ekuhlanzeni izandla, kanye neensetjenziswa zokuhlanza.
Phezu kwalokho, ama-alkyl polyether asetjenziswa njenge-demulsifiers kanye nama-lubricants embonini ye-petroleum, kanye nama-coolants kanye nama-lubricants ekusebenzeni kwensimbi.
Ikambiso yokukhiqiza ama-alkyl polyethers ivamise ukufaka hlangana ukuphathwa kwangaphambilini kwama-initiators nama-catalysts, ukusabela kwe-ring-opening polymerization, kanye namagadango wokusebenza ngemva kokusebenza afana nokungathathi hlangothi, ukudonsa, ukuphelelwa ngamanzi, ukuhlunga, nokuvundiswa.

Ngokufingqa
Ngokurhunyeziweko, ama-alkyl polyethers, njengezinto ezisebenzako ezinengi zamakhemikhali, adlala indima eqakathekileko emabubulweni amanengi. Azithuthukisi ukusebenza kwemikhiqizo nekhwalithi kwaphela kodwana zisekela nokuthuthukiswa kwebubulo lesimanjemanje. Ngokuragela phambili kwethekhnoloji, amathuba wokusetjenziswa kwama-alkyl polyethers azokubanzi khulu.
