Ukufunda Ngokulungiswa Kwesikhumba Se-Waterborne Polyurethane
Enkambweni yokukhiqizwa kwesikhumba, ukuqeda kuyinqubo ebaluleke kakhulu, enomthelela obaluleke kakhulu ekusetshenzisweni kwenani lesikhumba.Ngokuthuthuka komnotho kanye nokuthuthuka okuqhubekayo kwamazinga okuphila abantu, abantu banezidingo eziphakeme neziphakeme zama-agent aqeda isikhumba, futhi eminyakeni yamuva, kancane kancane baye basondela ohlotsheni oluvumelana nemvelo.I-ejenti yokuqeda isikhumba se-polyurethane emanzini ingagwema ngokuphumelelayo ukungcola kanye nobuthi be-ejenti yokuqedela yendabuko, futhi inezici zokugcinwa okulula, ukuthutha nokungashisi.Inokusebenza okuhle kakhulu, kodwa isenakho ukushiyeka kokungaguquki nokumelana namanzi.Idinga abasebenzi abafanelekile ukuze bahlole futhi balungise i-ejenti yokuqedela lesikhumba ye-polyurethane emanzini.

Ukusetshenziswa Koyinki Wokuvikelwa Kwemvelo Esekelwe Emanzini Ekupakishweni Kokudla
Njengohlobo olusha lwezinto zokupakisha nokuphrinta, inzuzo enkulu ye-inki esekelwe emanzini ukuthi ayinazo izinyibilikisi zemvelo eziguquguqukayo.Ukusetshenziswa kwayo kunciphisa inani lezinto eziphilayo ezishintshashintshayo (VOCs), akulimazi impilo yabakhiqizi beyinki nabanyathelisi, futhi kuthuthukisa ikhwalithi yemvelo.Ngakho-ke, ingabizwa ngokuthi inkino yemvelo.Izici ezinkulu zikayinki osuselwe emanzini akukhona ukungcoliswa kwemvelo, akukho mthelela empilweni yomuntu, akukho ukusha, nokuphepha okuhle.Akukwazi nje ukunciphisa ubuthi obusele ebusweni bemikhiqizo ephrintiwe, kwenze kube lula ukuhlanza imishini yokunyathelisa, kodwa futhi kunciphise ingozi yomlilo ebangelwa ugesi omile kanye nezincibilikisi ezivuthayo.Ngaphezu kokuvikelwa kwemvelo, izici zokuphrinta zikayinki osekelwe emanzini nazo zinhle.I-inki esekelwe emanzini inokusebenza okuzinzile, ayigqwali ipuleti, ukusebenza okulula, intengo ephansi, ukunamathela okuhle ngemva kokunyathelisa, ukumelana kwamanzi okuqinile nokomisa ngokushesha.Ama-inki asekelwe emanzini awasetshenziswa kuphela ekunyatheliseni kwe-flexographic kanye nokunyathelisa kwesikrini okunamandla amakhulu okuthuthukiswa.

Funda Ngokusetshenziswa Kwe-resin Esekelwe Ngamanzi Ku-Microfiber
Izinkinga zobuchwepheshe ezibhekene ne-Microfiber:
1.1 ukuntuleka kokungena komoya nokungena komswakama:
Ngemuva kokwelashwa kwangaphambilini kwesikhumba se-super fiber, ungqimba olungaphezulu kanye nongqimba lwe-adhesive luyaphathwa, okuholela ekungeneni komoya kanye nokungena komswakama.Ngokuvamile, i-resin ephezulu yesikhumba se-super fiber yi-TPU noma i-oily PU resin, ngoba kulula ukwenza ifilimu.Kodwa-ke, iphinde ibe nokubi okuthile, njengokuthi akukho ukungena komoya kanye nokungena komswakama ngemva kokumbozwa.Lokhu kuholela ekusebenzeni okuyingqayizivele kwe-super fiber ethintekayo futhi ayisenazo izinzuzo.
