Uyenza kanjani i-10% APS yamajeli?

Isingeniso:

I-Polymer APS idlala indima ebalulekile embonini yesimanje, futhi izakhiwo zayo ezisebenzayo ziyenza isetshenziswe kabanzi emikhakheni ehlukahlukene. I-APS ayibonisi nje ukumelana nesimo sezulu esihle kakhulu nokuzinza kwamakhemikhali, kodwa futhi ikhombisa izakhiwo ezinhle kakhulu zemishini nezikagesi, okuyenza ibe ukukhetha okuhle kwezinto eziningi. Phakathi kwazo, ijeli ye-APS, njengokuphuma kwe-APS, ibonise inani eliyingqayizivele lesicelo emikhakheni eminingi.

Kulo mongo, lesi sihloko sizoxoxa ngokubaluleka kokwenza ijeli ye-APS engu-10%. Ngokutadisha inqubo yokulungiselela kanye nezakhiwo zejeli ye-APS ngokuningiliziwe, singaqonda ngokujulile amandla kanye nezinzuzo zale nto ekusetshenzisweni okungokoqobo. Ezinhlelweni eziningi, ukulungiswa kwejeli ye-APS engu-10% akugcini nje ukudlala indima ebalulekile ekuthuthukiseni ukusebenza kwe-APS, kodwa futhi kunokubaluleka okubalulekile okusebenzayo emikhakheni yezinto ze-elekthronikhi, okokumboza, amadivaysi ezokwelapha, njll.

Ngakho-ke, ngokuxoxa ngokubaluleka kokulungiswa kwejeli ye-APS engu-10%, singaqonda kangcono amathemba okusetshenziswa kwezinto ze-APS, futhi sinikeze ukukhanyiselwa okuwusizo kocwaningo nokuthuthukiswa kwezimboni emikhakheni ehlobene.

Ukuqonda i-APS:

Igama eliphelele le-APS yi-Acrylonitrile Butadiene Styrene Copolymer. I-APS iyimpahla ye-polymer enesakhiwo se-molecular ehlanganisa ama-monomers amathathu: i-butyl acrylate, i-benzyl acrylate, ne-propylene acrylate. Le copolymer inezinto eziningi ezinhle kakhulu, okwenza isetshenziswe kabanzi emikhakheni ehlukene.

 

Imisebenzi ye-APS ibonakala kakhulu ekumelaneni kwayo nesimo sezulu, ukuqina kwamakhemikhali, izakhiwo zemishini nezikagesi. Inokumelana nesimo sezulu esihle kakhulu futhi ingagcina uzinzo ezindaweni ezinokhahlo, iyenze ibe yinhle kakhulu ezindaweni ezingaphandle nezinezinga eliphezulu lokushisa. Ngaleso sikhathi, i-APS iphinde ikhombise ukuzinza okuphezulu kwamakhemikhali nokumelana okuhle nezinto eziningi zamakhemikhali. Mayelana nokusebenza kwemishini, i-APS inamandla amakhulu nokuqina, okwenza idume kakhulu ekukhiqizeni amapulasitiki obunjiniyela ahlukahlukene kanye nemikhiqizo ehlala isikhathi eside. Ngaphezu kwalokho, i-APS iphinde ibe nokusebenza kahle kukagesi futhi ilungele izinkambu ze-elekthronikhi nezinto zikagesi.

Kujeli, indima ye-APS ibonakala ngokulungiselela ijeli ye-APS. Ijeli ye-APS ivamise ukwakhiwa ngokuxuba i-APS ne-solvent efanele noma ingxube kanye ne-polymerizing ngaphansi kwezimo ezithile. Ijeli ye-APS idlala indima ebalulekile ekucutshungulweni nasekusetshenzisweni kwezinto ezibonakalayo, ihlinzeka ngefomu lezinto ezibonakalayo elinepulasitiki elihle kanye nokubumba okulula. I-APS efomini yejeli isetshenziswa kakhulu ekubanjeni, emikhiqizweni yepulasitiki, emishinini yezokwelapha nakwezinye izinkambu, ihlinzeka ngezinhlobonhlobo zokusebenza nezici zokusetshenziswa kwemikhiqizo kule mikhakha.

Indawo yaselabhorethri yokulungiselela:
