Isifinyezo: Lesi sihloko sethula ikakhulukazi amaphuzu okulawula enqubo yokuhlanganiswa engenazo izinyibilikisi, okuhlanganisa, ukulawula izinga lokushisa, ukulawula inani lokumboza, ukulawula ukucindezeleka, ukulawula ingcindezi, ukufaniswa kweyinki neglue, ukulawula umswakama nendawo okuyo, ukushisa kweglue kusengaphambili, njll.
Izinhlanganisela ezingenaso isinyibilikisi ziya ngokuya zisetshenziswa, futhi indlela yokusebenzisa kahle le nqubo iyindaba ekhathaza wonke umuntu. Ukuze kusetshenziswe kahle izinhlanganisela ezingenaso isinyibilikisi, umbhali uncoma kakhulu ukuthi amabhizinisi anezimo asebenzise imishini eminingi engenaso isinyibilikisi noma amasilinda eglue amabili, okungukuthi, asebenzise amasilinda amabili eglue, elinye liqukethe inhlaka ehlanganisa ingxenye enkulu yesakhiwo somkhiqizo, kanti elinye likhetha inhlaka esebenzayo efanelekela ubuso noma ungqimba lwangaphakathi njengesengezo ngokusekelwe esakhiweni somkhiqizo wekhasimende.
Izinzuzo zokusebenzisa isilinda senjoloba esiphindwe kabili yilezi: kungandisa ububanzi bokusetshenziswa kwezinhlanganisela ezingenaso isinyibilikisi, kunciphise ukukhishwa komoya, kube nezindleko eziphansi, kanye nokusebenza kahle okuphezulu. Futhi asikho isidingo sokuhlanza isilinda seglue njalo, ukushintsha izinamathiseli, nokunciphisa imfucuza. Ungakhetha futhi izinamathiseli ngokusekelwe kumkhiqizo nezidingo zamakhasimende ukuqinisekisa ikhwalithi yomkhiqizo.
Enkambisweni yenkonzo yamakhasimende yesikhathi eside, ngifingqe amanye amaphuzu okulawula izinqubo okumele aqashelwe ukuze kwenziwe umsebenzi omuhle ku-composite engenazo izinyibilikisi.
1. Hlanza
Ukuze uthole inhlanganisela enhle engenazo izinyibilikisi, into yokuqala okufanele uyenze ukuhlanzeka, okuyiphuzu elilula ukulikhohlwa yizinkampani.
I-roller eqinile engaguquki, i-roller eqinile yokulinganisa, i-roller yokumboza, i-roller yokucindezela yokumboza, i-roller eqinile ehlanganisiwe, ishubhu yomhlahlandlela wokuxuba, i-barrel eyinhloko neye-curing yomshini wokuxuba, kanye nama-roller ahlukahlukene omhlahlandlela, kumele ahlanzeke futhi angabi nezinto zakwamanye amazwe, ngoba noma iyiphi into yangaphandle kulezi zindawo izobangela amabhamuza namabala amhlophe ebusweni befilimu ehlanganisiwe.
2. Ukulawula izinga lokushisa
Isithako esiyinhloko se-adhesive engenaso i-solvent yi-NCO, kanti i-ejenti yokwelapha iyi-OH. Ubuningi, i-viscosity, ukusebenza kwama-ejenti ayinhloko kanye ne-curing, kanye nezici ezifana nokuphila kwenkonzo, izinga lokushisa, izinga lokushisa lokwelapha, kanye nesikhathi se-adhesive, konke kungathinta ikhwalithi ye-composite.
I-polyurethane adhesive engenaso isinyibilikisi inobuthi obukhulu ekushiseni kwegumbi ngenxa yokungabikho kwama-molecule amancane anyibilikisayo, amandla aphezulu aphakathi kwama-molecule, kanye nokwakheka kwama-hydrogen bond. Ukushisa kunganciphisa ngempumelelo ubuthi, kodwa amazinga okushisa aphezulu kakhulu angaholela kalula ekuqhekekeni, kukhiqize ama-resin anesisindo sama-molecule amaningi, okwenza ukumbozwa kube nzima noma kungalingani. Ngakho-ke, ukulawula izinga lokushisa lokumboza kubaluleke kakhulu.
Ngokuvamile, abahlinzeki be-glue bazonikeza amakhasimende amanye amapharamitha okusetshenziswa njengereferensi, futhi izinga lokushisa lokusetshenziswa ngokuvamile linikezwa njengenani lebanga.
Uma izinga lokushisa liphezulu ngaphambi kokuxuba, kulapho i-viscosity iphansi khona; uma izinga lokushisa liphezulu ngemva kokuxuba, kulapho i-viscosity iphakama khona.
Ukulungiswa kwezinga lokushisa kwe-roller yokulinganisa kanye ne-roller yokumboza kuncike kakhulu ekuqineni kwe-glue. Uma i-viscosity ye-glue iphakeme, izinga lokushisa le-roller yokulinganisa liphakeme. Izinga lokushisa le-roller ehlanganisiwe ngokuvamile lingalawulwa cishe ku-50 ± 5 ° C.
3. Ukulawula inani leglue
Ngokwezinto ezihlanganisiwe ezahlukene, amanani ahlukene eglue angasetshenziswa. Njengoba kuboniswe etafuleni, ububanzi obulinganiselwe benani leglue bunikezwa, futhi ukulawulwa kwenani leglue ekukhiqizweni kunqunywa kakhulu yigebe kanye nesilinganiso sejubane phakathi kwerola yokulinganisa kanye nerola ehleliwe.Inani lesicelo seglue
4.ukulawula ukucindezela
Ngenxa yokuthi i-coating roller ilawula inani le-glue esetshenziswa yi-gap kanye nesilinganiso sejubane phakathi kwama-light rollers amabili, ubukhulu bengcindezi ye-coating buzothinta ngqo inani le-glue esetshenziswayo. Uma ingcindezi iphakeme, inani le-glue esetshenziswayo lincane.
5. Ukuhambisana phakathi kweyinki neglue
Ukuhambisana phakathi kwezinamathelisi ezingenaso isinyibilikisi kanye noyinki ngokuvamile kuhle kulezi zinsuku. Kodwa-ke, lapho izinkampani zishintsha abakhiqizi beyinki noma izinhlelo zokunamathelisa, kusadingeka zenze ukuhlolwa kokuhambisana.
6. Ukulawula ukucindezeleka
Ukulawulwa kokucindezeleka kubaluleke kakhulu ku-composite engenaso isinyibilikisi ngoba ukunamathela kwayo kokuqala kuphansi impela. Uma ukucindezeleka kwe-membrane yangaphambili neyangemuva kungafani, kungenzeka ukuthi ngesikhathi senqubo yokuvuthwa, ukuncipha kwe-membrane kungase kuhluke, okuholela ekubonakaleni kwamabhamuza kanye nemigudu.
Ngokuvamile, ukudla kwesibili kufanele kuncishiswe ngangokunokwenzeka, futhi kuma-film amakhulu, ukucindezeleka kanye nokushisa kwe-composite roller kufanele kukhuliswe ngokufanele. Zama ukugwema ukugoba kwe-composite film ngangokunokwenzeka.
7. Lawula umswakama kanye nendawo okuyo
Njalo qapha izinguquko zomswakama bese ulungisa isilinganiso se-ejenti eyinhloko kanye ne-ejenti yokwelapha ngokufanele. Ngenxa yesivinini esisheshayo se-composite engenaso isinyibilikisi, uma umswakama uphezulu kakhulu, ifilimu ehlanganisiwe embozwe nge-glue izoqhubeka nokuxhumana nomswakama osemoyeni, idle i-NCO ethile, okuholela ezimweni ezifana ne-glue engomi kanye nokuxebuka okubi.
Ngenxa yesivinini esiphezulu somshini wokulamina ongenaso isinyibilikisi, i-substrate esetshenziswayo izokhiqiza ugesi ongashintshi, okubangela ukuthi ifilimu yokunyathelisa imunce kalula uthuli nokungcola, okuthinta ikhwalithi yomkhiqizo. Ngakho-ke, indawo yokusebenza yokukhiqiza kufanele ivalwe kancane, igcine indawo yokusebenzela ingaphakathi kwezinga lokushisa elidingekayo kanye nomswakama.
8. Ukunamathisela ukushisa kwangaphambili
Ngokuvamile, inhlaka ngaphambi kokungena kwisilinda idinga ukushiswa kusengaphambili, futhi inhlaka exubile ingasetshenziswa kuphela ngemva kokushiswa ezingeni lokushisa elithile ukuqinisekisa izinga lokudluliselwa kwenhlaka.
9. Isiphetho
Esigabeni samanje lapho inhlanganisela engenaso isinyibilikisi kanye nenhlanganisela eyomile kuhlangana khona, amabhizinisi adinga ukukhulisa ukusetshenziswa kwemishini kanye nenzuzo. Inqubo ingaba yinhlanganisela engenaso isinyibilikisi, futhi ngeke ibe yinhlanganisela eyomile. Hlela ukukhiqiza ngendlela efanele nangempumelelo, futhi usebenzise imishini ekhona ngempumelelo. Ngokulawula inqubo kanye nokusungula izincwadi zokusebenza ezinembile, ukulahlekelwa kokukhiqiza okungadingekile kungancishiswa.
