Ngokuhamba kweminyaka, ukukhiqizwa kwama-roller enjoloba kuye kwenza ukushintshwa kwemishini kanye nokuzenzakalelayo kwemishini yenqubo kube nzima ngenxa yokungaqini kwemikhiqizo kanye nokwehlukahlukana kokucaciswa kosayizi.Kuze kube manje, iningi lazo liseyimigqa yokukhiqiza yokusebenza kweyunithi esekelwe ngesandla.Muva nje, abanye abakhiqizi abakhulu abangochwepheshe baqale ukubona ukukhiqizwa okuqhubekayo kusukela ezintweni zenjoloba kuya ezinqubweni zokubumba kanye ne-vulcanization, okuphindaphinde kabili ukusebenza kahle kokukhiqiza futhi kwathuthukisa kakhulu indawo yokusebenza kanye nokuqina kwabasebenzi.
Eminyakeni yamuva nje, ubuchwepheshe bomjovo, i-extrusion kanye ne-winding buye bathuthukiswa ngokuqhubekayo, futhi imishini yokubumba yerabha yerabha kanye ne-vulcanization yenze ukukhiqizwa kwe-rubber roller kancane kancane kwaba mshini futhi ku-othomathikhi.Ukusebenza kwe-roller yerabha kunomthelela omkhulu kuwo wonke umshini, futhi kuqine kakhulu ekusebenzeni kwenqubo kanye nekhwalithi yokukhiqiza.Imikhiqizo yayo eminingi ihlukaniswe njengemikhiqizo emihle.Phakathi kwazo, ukukhethwa kwezinto zenjoloba nepulasitiki kanye nokulawulwa kokunemba kobukhulu bomkhiqizo kuyisihluthulelo.I-rubber surface ye-rubber roller ayivunyelwe ukuba nanoma yikuphi ukungcola, ama-blister nama-bubbles, ingasaphathwa izibazi, amaphutha, ama-grooves, imifantu kanye nezipontshi zendawo kanye nezimo ezihlukahlukene ezithambile neziqinile.Ngalesi sizathu, i-roller yerabha kufanele ihlanzeke ngokuphelele futhi icophelele kuyo yonke inqubo yokukhiqiza, ukuze ibone ukusebenza okuhlangene kanye nokumiswa kobuchwepheshe.Inqubo yokuhlanganisa ipulasitiki yenjoloba kanye nomgogodla wensimbi, ukunamathisela, ukubumba umjovo, i-vulcanization nokugaya ngakho-ke kube inqubo yobuchwepheshe obuphezulu.
Ukulungiswa kwerabha
Kumarola enjoloba, ukuxutshwa kwenjoloba kuyisixhumanisi esibaluleke kakhulu.Kunezinhlobo ezingaphezu kweziyi-10 zezinto zenjoloba zamarola enjoloba kusukela kurabha yemvelo kanye nerabha yokwenziwa kuye ezintweni ezikhethekile.Okuqukethwe kwenjoloba kungu-25% -85%, kanti ubulukhuni umhlabathi (0-90) degrees, ohlanganisa ububanzi obubanzi.Ngakho-ke, indlela yokuxuba lezi zinhlanganisela ngokulinganayo sekuyinkinga enkulu.Indlela evamile iwukusebenzisa isigayo esivulekile sokuxuba nokucubungula ngendlela yamaqoqo ayinhloko ahlukahlukene.Eminyakeni yamuva, izinkampani ziye zashintsha ngokuya ekuxubeni kwangaphakathi ukuze zilungise izingxube zenjoloba ngokusebenzisa ukuxuba okuhlukene.
Ngemuva kokuthi izinto zenjoloba zixutshwe ngokulinganayo, irabha kufanele ihlungwe ngesihlungi senjoloba ukuze kuqedwe ukungcola ezintweni zenjoloba.Bese usebenzisa i-calender, i-extruder, kanye nomshini wokugcoba ukuze wenze ifilimu noma umdweshu ngaphandle kwamabhamuza nokungcola kokwakhiwa kwe-roller yerabha.Ngaphambi kokwakhiwa, lawa mafilimu nemichilo yokunamathisela kufanele ihlolwe ngokuqinile ukuze kukhawulwe isikhathi sokupaka, kugcinwe indawo ehlanzekile futhi kuvimbele ukunamathela nokuguquguquka kwe-extrusion.Ngenxa yokuthi ama-roller amaningi enjoloba ayimikhiqizo engabunjiwe, uma sekukhona ukungcola namabhamuza ebusweni benjoloba, amabhamuza angase avele lapho indawo iphansi ngemva kokukhishwa kwe-vulcanization, okuzokwenza ukuthi yonke i-roller yerabha ilungiswe noma ikhishwe.
