Okufingqiwe:Le ndatshana yethula ikakhulukazi amaphuzu okulawula wenqubo eyinhlanganisela engena-solvent, okubandakanya, ukulawula izinga lokushisa, ukulawulwa kwenani lokumboza, ukulawulwa kwengcindezi, ukulawula ingcindezi, ukufanisa uyinki neglue, ukulawula umswakama nendawo yakhona, ukushisa kweglue, njll.
Izinhlanganisela zamahhala ezincibilikayo ziya ngokuya zisetshenziswa, futhi indlela yokusebenzisa kahle le nqubo kuyisihloko esikhathaza wonke umuntu.Ukuze usebenzise kahle izinhlanganisela ezingenazo i-solvent, umbhali uncoma ngokuqinile ukuthi amabhizinisi anemibandela asebenzise imishini eminingi engena-solvent noma amasilinda eglue aphindwe kabili, okungukuthi, asebenzise amasilinda eglue amabili, elinye eliqukethe ingcina yendawo yonke ehlanganisa ingxenye enkulu yesakhiwo somkhiqizo, kanti enye ikhetha ingcina esebenzayo efanele indawo engaphezulu noma isendlalelo sangaphakathi njengesithasiselo esisekelwe esakhiweni somkhiqizo wekhasimende.
Izinzuzo zokusebenzisa isilinda senjoloba ephindwe kabili yilezi: ingakhuphula ububanzi bohlelo lwezinhlanganisela ezingancibiliki, inciphise ukungcola, ibe nezindleko eziphansi, nokusebenza kahle okuphezulu.Futhi asikho isidingo sokuhlanza njalo isilinda seglue, ukushintsha okunamathelayo, nokunciphisa imfucuza.Ungaphinda ukhethe okunamathelayo okususelwa kumkhiqizo nezidingo zekhasimende ukuze uqinisekise ikhwalithi yomkhiqizo.
Enqubweni yesevisi yamakhasimende yesikhathi eside, ngiphinde ngafingqa amanye amaphuzu okulawula inqubo okufanele inakwe ukuze kwenziwe umsebenzi omuhle ekuhlanganiseni okungancibiliki.
1.Hlanza
Ukuze kuzuzwe inhlanganisela enhle engancibiliki, into yokuqala okufanele yenziwe wukuhlanzeka, okuyiphuzu futhi okunganakwa kalula ngamabhizinisi.
I-roller eqinile engaguquki, i-roller eqinile yokulinganisa, i-coating roller, i-coating pressure roller, i-composite rigid roller, ithubhu yokuqondisa ukuxuba, umgqomo we-ejenti oyinhloko nokwelapha womshini wokuxuba, kanye nama-roller ahlukahlukene aqondisayo, kufanele ahlanzeke futhi angabi nezinto zangaphandle, ngoba noma iyiphi into yangaphandle kulezi zindawo izodala amabhamuza namachashaza amhlophe ebusweni befilimu eyinhlanganisela.
2.Ukulawula izinga lokushisa
Isithako esiyinhloko se-adhesive-free adhesive i-NCO, kuyilapho i-ejenti elaphayo ingu-OH.Ukuminyana, i-viscosity, ukusebenza kwe-ejenti eyinhloko nelaphayo, kanye nezici ezifana nempilo yesevisi, izinga lokushisa, izinga lokushisa lokuphulukisa, nesikhathi sokunamathela, konke kungathinta ikhwalithi yenhlanganisela.
I-solvent yamahhala ye-polyurethane adhesive ine-viscosity ephezulu ekamelweni lokushisa ngenxa yokungabikho kwama-molecule amancane e-solvent, amandla aphezulu e-intermolecular, nokwakhiwa kwamabhondi e-hydrogen.Ukushisa kunganciphisa ngempumelelo i-viscosity, kodwa amazinga okushisa aphakeme ngokweqile angaholela kalula ku-gelation, okukhiqiza ama-resin amangqamuzana aphezulu, okwenza ukunamathela kube nzima noma ukungalingani.Ngakho-ke, ukulawula izinga lokushisa lokugqoka kubaluleke kakhulu.
Ngokuvamile, abahlinzeki bezinto ezinamathelayo bazohlinzeka amakhasimende ngemingcele ethile yokusetshenziswa njengereferensi, futhi izinga lokushisa lokusetshenziswa ngokuvamile linikezwa njengenani lebanga.
Ukuphakama kwezinga lokushisa ngaphambi kokuxuba, i-viscosity ephansi;lapho izinga lokushisa liphakeme ngemva kokuxuba, i-viscosity iyanda.
Ukulungiswa kwezinga lokushisa kwe-roller yokulinganisa kanye ne-coating roller ikakhulukazi kuncike ku-viscosity ye-adhesive.Ukuphakama kwe-viscosity ye-adhesive, izinga lokushisa eliphakeme le-roller yokulinganisa.Izinga lokushisa le-roller eliyinhlanganisela lingalawulwa cishe ku-50 ± 5 ° C.
3.Glue ukulawulwa kwenani
Ngokwezinto ezihlukene eziyinhlanganisela, amanani ahlukene eglue angasetshenziswa.Njengoba kuboniswe kuthebula, isilinganiso sebanga lenani leglue liyanikezwa, futhi ukulawulwa kwenani leglue ekukhiqizeni kunqunywa ngokuyinhloko igebe nesilinganiso sesivinini phakathi kwerola yokulinganisa nerola engaguquki.Inani lesicelo seglue
4.ukulawula ingcindezi
Ngenxa yokuthi i-coating roller ilawula inani leglue elisetshenziswa yi-gap nesilinganiso sejubane phakathi kwama-roller amabili akhanyayo, ubukhulu bengcindezi yokugqoka buzothinta ngqo inani leglue elisetshenzisiwe.Ukuphakama kwengcindezi, kuncane inani leglue elisetshenzisiwe.
5.Ukuhambisana phakathi kukayinki neglue
Ukuhambisana phakathi kwezinamatheliso ezingancibilikiyo kanye noyinki ngokuvamile kuhle kulezi zinsuku.Kodwa-ke, lapho izinkampani zishintsha abakhiqizi be-inki noma izinhlelo zokunamathela, zisadinga ukwenza ukuhlolwa kokuhambisana.
6.Ukulawula ukuqina
Ukulawula ukucindezeleka kubaluleke kakhulu ekuhlanganiseni okungancibiliki ngenxa yokuthi ukunamathela kwayo kokuqala kuphansi kakhulu.Uma ukungezwani kwe-membrane yangaphambili nangemuva kungahambisani, kungenzeka ukuthi ngesikhathi senqubo yokuvuthwa, ukuncipha kwe-membrane kungase kuhluke, okuholela ekubukeni kwama-bubbles kanye nemigudu.
Ngokuvamile, ukuphakelwa kwesibili kufanele kuncishiswe ngangokunokwenzeka, futhi kumafilimu aminyene, ukungezwani nokushisa kwe-roller eyinhlanganisela kufanele kukhuliswe ngokufanele.Zama ukugwema ukugoqa kwefilimu eyinhlanganisela ngangokunokwenzeka.
7.Lawula umswakama nendawo yawo
Qaphela izinguquko zomswakama futhi ulungise isilinganiso se-ejenti eyinhloko kanye ne-ejenti yokwelapha ngokufanele.Ngenxa yejubane elisheshayo lenhlanganisela engancibiliki, uma umswakama uphezulu kakhulu, ifilimu eyinhlanganisela ehlanganiswe neglu lisazohlangana nomswakama osemoyeni, kudle i-NCO ethile, okuholela ezenzweni ezifana ne-glue engomi futhi impofu. ukuxebuka.
Ngenxa yesivinini esikhulu somshini we-laminating we-solvent-free, i-substrate esetshenzisiwe izokhiqiza ugesi omile, okwenza ifilimu yokunyathelisa ibambe kalula uthuli nokungcola, okuthinta izinga lokubukeka lomkhiqizo.Ngakho-ke, indawo yokusebenza yokukhiqiza kufanele ivalwe ngokuqhathaniswa, igcine ishabhu ngaphakathi kwebanga lokushisa elidingekayo kanye nomswakama.
8.Glue preheating
Ngokuvamile, i-glue ngaphambi kokungena ku-cylinder idinga ukushiswa kusengaphambili, futhi i-glue ehlanganisiwe ingasetshenziswa kuphela ngemva kokushiswa ekushiseni okuthile ukuze kuqinisekiswe izinga lokudlulisa leglue.
9.Isiphetho
Esigabeni samanje lapho inhlanganisela engancibiliki neyomile ihlangana ndawonye, amabhizinisi adinga ukukhulisa ukusetshenziswa kwemishini kanye nenzuzo.Inqubo ingaba yinhlanganisela engancibiliki, futhi ayisoze yaba yinhlanganisela eyomile.Hlela ukukhiqiza ngokunengqondo nangempumelelo, futhi usebenzise amathuluzi akhona ngempumelelo.Ngokulawula inqubo kanye nokusungula iziqondiso ezinembile zokusebenza, ukulahlekelwa kokukhiqiza okungadingekile kungancishiswa.
