I-adhesive encibilikayo eshisayoluhlobo lweingcina yepulasitiki, isimo sayo somzimba singashintsha ngokushintsha kwezinga lokushisa, kodwa izakhiwo zayo zamakhemikhali ngeke zishintshe, ngakho-ke ukunamathela okuncibilika okushisayo kunokusebenza okuhle kakhulu kwemvelo.I-adhesive ye-hot melt ngokwayo iqinile, ethandwa yizinzuzo zokupakisha okulula, ezokuthutha, isitoreji, inqubo yokukhiqiza elula, inani eliphakeme elingeziwe, amandla okubopha okuphezulu kanye nesivinini esisheshayo.
Ukubukeka kwethu okuvamile kokunamathelisa okuncibilika okushisayo kumhlophe ikakhulukazi, kanti okunye kusobala.Ngakho-ke yini okufanele siyenze ukuze senze ingcina encibilikayo eshisayo icace futhi ibe mhlophe?U-Subang uncoma ukwengeza inani elincane lamanzi phakathi nenqubo yokukhiqiza.I-ejenti emhlophe enamathelayo enamathelayo eyi-fluorescent eshisayo.
I-ethylene kanye ne-vinyl acetate yizinhlaka eziyisisekelo zokunamathela okuncibilika okushisayo, okwenziwe nge-copolymerized ngaphansi kwezinga lokushisa eliphezulu nokucindezela okuphezulu, okuyi-resin EVA.I-EVA resin iyisakhi esiyinhloko sokwenza okunamathelayo okuncibilika okushisayo, futhi ukusebenza okuyisisekelo kokunamathela okuncibilika okushisayo kunqunywa isilinganiso kanye nekhwalithi ye-resin.Kodwa-ke, kubaluleke kakhulu ukukhetha i-EVA melt finger.Uma umunwe uncibilika ube mncane, i-fluidity iba mpofu futhi amandla amakhulu.Uma izinga lokushisa elincibilikayo liphezulu, kuba mpofu kakhulu ukumanzisa kanye nokungena kwamanzi okunamathelayo.Ngokuphambene nalokho, uma inkomba yokuncibilika inkulu kakhulu, izinga lokushisa elincibilikayo leglue liphansi, uketshezi luhle, kodwa amandla okubopha ayancipha.Ukukhethwa komsizi wayo, kungcono ukwenza isilinganiso se-ethylene ne-vinyl acetate efanele.
Okokuqala, yakha amafomula anengqondo anezilinganiso ezihlukene zezinto zokusetshenziswa, engeza izinto zokusetshenziswa zokunamathisela ezincibilikisiwe ezilungisiwe egedlela lokusabela, bese uxuba inani elifanele le-ejenti emhlophe e-fluorescent yokunamathela okuncibilika okushisayo nezinto zokusetshenziswa ngokulinganayo ekukhiqizeni, ngokuvamile okukodwa. ithani lezinto zokusetshenziswa Ukwengeza cishe u-200g kungazuza imiphumela emihle kakhulu.
Khulisa izinga lokushisa ukuze uncibilike futhi ugovuze kahle.Bese upholisa irabha encibilikisiwe eketelani lokusabela ekushiseni okuthile bese uyifaka ku-extruder esebenzayo.Ijubane le-extrusion le-extruder lingakhethwa ngokusho kwezinhlobo ezahlukene zenjoloba.
I-extruder ingxilisa okunamathelayo okuncibilika okushisayo ethangini lamanzi ngembobo eyindilinga ye-extrusion ekhanda le-extrusion.I-adhesive ye-hot-melt yakheka ngokushesha lapho ihlangana namanzi apholile.Induku yeglue ipholiswa kuqala bese ilolongwa ngethangi lamanzi okupholisa lokuqala.Umshini wokudonsa womshini wokufafaza ngeglue ungena ethangini lesibili lamanzi okupholisa, futhi isampula yeglue ipholiswe ngokuphelele futhi yakhiwe ethangini lamanzi okupholisa lesibili.Ijubane lokugijima lenduku yeglue ethangini lamanzi lilawulwa isivinini se-extrusion se-extruder, ukuze umshini wokudonsa Isivinini sokudonsa sivumelaniswe nesivinini sokukhipha i-extruder.
Lungisa futhi ulawule ubudlelwano phakathi kwejubane le-extrusion, isivinini sokusetha ukupholisa kanye nesivinini sokudonsa, bese uyasikela futhi upakishe ingcina encibilikisiwe eshisayo emikhiqizweni ephelile.Inani elimhlophe le-adhesive encibilikayo eshisayo ngemva kokwengeza i-i-agent emhlophe ye-fluorescentngokusobala ithuthukiswa ngamaphuzu amaningana, futhi akulula ukuphuzi esigabeni sakamuva.
