I-Thickener Yokuphrinta

I-Thickener Yokuphrinta

Ama-thickeners okuphrinta angenye yezinto ezivame ukusetshenziswa kakhulu embonini yokunyathelisa.Ekuphrinteni, izinto ezimbili eziyinhloko ezisetshenziswayo iglue nokunamathisela umbala.Futhi ngenxa yokuthi ukungaguquguquki kuzokwehla ngaphansi kwamandla aphezulu okugunda, ama-thickeners asetshenziselwa ukwandisa ukungaguquguquki kwezinto zokuphrinta, futhi izingqimba zokuphrinta ziyadingeka ngalesi sikhathi.

Umsebenzi oyinhloko we-thickener yokunyathelisa ukuhlinzeka ngezakhiwo ezinhle ze-rheological, ukudlulisa iglue noma unamathisele umbala esikrinini sokunyathelisa kanye ne-roller yokunyathelisa kwendwangu, ukuze idayi ne-fiber kuhlanganiswe ndawonye ukuze kuqinisekiswe iphethini yokuphrinta ecacile.Iphethini icacile futhi umbala ugqamile futhi umfaniswano;lapho udayi ulungisiwe, imikhiqizo yokusabela kanye nezinsalela zisuswa kalula enkambweni engezansi, okwenza indwangu izwakale ithambile.Lokhu kubonisa ukuthi imishini yokunyathelisa idlala indima ebaluleke kakhulu embonini yokunyathelisa.

I-Disperse printing thickener iyinhlanganisela ye-emulsion thickener ye-polymer ehlangene.Ngemuva kokuhlanjululwa futhi kuncishiswe ngamanzi, izinhlayiya ze-polymer ezisekelwe emanzini zizokhula ngokushesha.Kulokhu, umkhiqizo ophrintiwe uzocaca kakhulu futhi unamathele.I-thickener yokunyathelisa ye-disperse ingakhuphula ngempumelelo i-viscosity ye-shear ephansi yesistimu yokunyathelisa futhi yenze uhlelo lokunyathelisa lube ne-pseudoplasticity ephakeme.Ukuphrinta udayi okulungiselelwe nge-thickener yokunyathelisa yokusabalalisa njengoba i-thickener eyinhloko inenani eliphakeme lesivuno kanye nesakhiwo sejeli.Lesi sakhiwo asibonakali kuze kube yilapho amandla okugunda enyamalala.Ngakho-ke, i-thickener yokunyathelisa yokuhlakazeka ifaneleka ukulungiselela ukuphrinta ngomphumela omaphakathi wephethini enezinhlangothi ezintathu.

Ama-thickeners okuphrinta anomlando omude wokuthuthuka.Usayizi owawusetshenziswa kudala kwakuyisitashi noma isitashi esishintshiwe.Lolu hlobo lwe-thickener lubizwa ngokuthi i-thickener yemvelo, kodwa lolu hlobo lokuqina kokuphrinta lunezindleko eziphezulu, ukujula kombala okuphansi, ukungabonakali kahle, ukungasheshi ukuwashwa, kanye nokuthungwa kwendwangu okungagculisi.Njengamanje, lolu hlobo lwe-thickener seluqediwe.Kwaze kwaba ngawo-1950 lapho abantu bethula khona i-pulp kazwelonke, eyenza ubuchwepheshe bokunyathelisa busetshenziswe kabanzi.Isebenzisa uphalafini namanzi njengezinto zokusetshenziswa, ingena kwi-emulsification enesivinini esikhulu ngaphansi kwesenzo se-emulsifiers ukuze yakhe i-state slurry thickener.Ngenxa yokuthi i-thickener iqukethe uphalafini ngaphezu kuka-50 # futhi inani likhulu, lizodala ukungcoliswa okukhulu emoyeni futhi libe sengozini yokuqhuma.Ngaphezu kwalokho, ukuvumelana kokunamathisela kokuphrinta akulula ukulungisa, futhi iphunga likaphalafini lizohlala phezu kwendwangu ngemva kokunyathelisa.Ngakho-ke abantu abakaneliseki ngalesi sishicileli sokunyathelisa.Ngawo-1970, abantu baqala ukuthuthukisa nokukhiqiza ama-thickeners okwenziwa.Ukuvela kwama-thickeners okwenziwa kuye kwakhuthaza kakhulu ukuthuthukiswa kokukhiqizwa kokunyathelisa futhi kwakhuphula ubuchwepheshe bokunyathelisa ezingeni elisha.Ixazulula izinkinga zokungcoliswa kwemvelo kanye nezokuphepha.Ngaphezu kwalokho, i-thickener yokwenziwa inezinzuzo zomphumela omuhle wokujiya, ukuthuthwa okulula nokugcinwa, ukulungiswa okulula, uhlaka olucacile, umbala ogqamile nokunye okunjalo.

Singabahlinzeki be-Disperse Printing Thickener.Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
