Ukubumba
Ukubunjwa kwe-rubber roller ikakhulukazi ukunamathisela irabha enamathela kumgogodla wensimbi, okuhlanganisa indlela yokugoqa, indlela ye-extrusion, indlela yokubumba, indlela yengcindezi yomjovo kanye nendlela yomjovo.Njengamanje, imikhiqizo yasekhaya eyinhloko inamathiselwe ngomshini noma ngesandla, futhi amazwe amaningi angaphandle aqaphele ukuzenzakalelayo kwemishini.Amarola enjoloba amakhulu naphakathi akhiqizwa ngokuyisisekelo nge-profiling extrusion, ukunamathisela okuqhubekayo ngefilimu ekhishwe noma ukubumba okugoqayo okuqhubekayo nge-tape ekhishwayo.Ngesikhathi esifanayo, enqubweni yokubumba, ukucaciswa, ubukhulu kanye nokuma kokubukeka kulawulwa ngokuzenzakalelayo yi-microcomputer, kanti okunye kungabunjwa ngendlela ye-extruder ye-right-angle kanye ne-extrusion emise okukhethekile.
Indlela yokubumba eshiwo ngenhla ayikwazi nje ukunciphisa amandla omsebenzi, kodwa futhi isuse ama-bubbles angenzeka.Ukuze uvimbele i-roller yerabha ekuwohlokekeni ngesikhathi se-vulcanization kanye nokuvimbela ukukhiqizwa kwamabhamuza nezipontshi, ikakhulukazi i-roller yerabha ebunjwe ngendlela yokugoqa, indlela yokucindezela eguquguqukayo kufanele isetshenziswe ngaphandle.Ngokuvamile, ingaphandle le-roller yenjoloba igoqwe futhi ilinyazwe ngezingqimba eziningana zendwangu kakotini noma indwangu yenayiloni, bese ilungiswa futhi icindezeleke ngocingo lwensimbi noma intambo ye-fiber.Nakuba le nqubo isivele seyenziwe ngemishini, ukugqokwa kufanele kususwe ngemva kokukhishwa kwe-vulcanization ukuze kwakhiwe inqubo "ye-cecal", eyenza inqubo yokukhiqiza ibe nzima.Ngaphezu kwalokho, ukusetshenziswa kwendwangu yokugqoka kanye nezintambo ezisongayo kulinganiselwe kakhulu futhi ukusetshenziswa kukhulu.imfucuza.
Kumarola erabha amancane namancane, izinqubo ezahlukahlukene zokukhiqiza zingasetshenziswa, njengokuphetshwa ngesandla, isidleke se-extrusion, ingcindezi yomjovo, umjovo kanye nokuthela.Ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza, izindlela eziningi zokubumba sezisetshenziswa manje, futhi ukunemba kuphakeme kakhulu kunaleyo yendlela engabumbi.Ukucindezela komjovo, umjovo werabha eqinile kanye nokuthululwa kwerabha ewuketshezi sekuphenduke izindlela zokukhiqiza ezibaluleke kakhulu.
I-Vulcanization
Okwamanje, indlela yokwenza i-vulcanization yamarola enjoloba amakhulu naphakathi iseyi-vulcanization tank vulcanization.Nakuba imodi ye-pressurization eguquguqukayo ishintshiwe, namanje ayihlukani nomthwalo osindayo womsebenzi wokuthutha, ukuphakamisa kanye nokuthulula.Umthombo wokushisa we-vulcanization unezindlela ezintathu zokushisisa: isitimu, umoya oshisayo namanzi ashisayo, kanti okujwayelekile kusewumusi.Ama-roller enjoloba anezidingo ezikhethekile ngenxa yokuxhumana komgogodla wensimbi nomhwamuko wamanzi athatha i-vulcanization ye-steam engaqondile, futhi isikhathi sizokwelulwa izikhathi ezi-1 kuye kwezi-2.Ngokuvamile isetshenziselwa ama-roller erabha anezinsimbi ezingenalutho.Kuma-roller enjoloba akhethekile angakwazi ukuvuthwa nge-vulcanizing tank, amanzi ashisayo ngezinye izikhathi asetshenziselwa i-vulcanization, kodwa ukwelashwa kokungcola kwamanzi kudinga ukuxazululwa.
Ukuze uvimbele injoloba kanye nomgogodla wensimbi ekuncipheni ngenxa yokushwabana okuhlukile komehluko we-rubber conduction phakathi kwe-roller yerabha kanye nomgogodla wenjoloba, i-vulcanization ngokuvamile isebenzisa indlela yokushisa ehamba kancane kanye nokwanda kwengcindezi, futhi isikhathi se-vulcanization siningi. isikhathi eside kunesikhathi sokwenza i-vulcanization esidingwa yirabha ngokwayo..Ukuze kuzuzwe i-vulcanization efanayo ngaphakathi nangaphandle, futhi ukwenza ukuguquguquka okushisayo kwengqikithi yensimbi nerabha kufane, i-roller enkulu yerabha ihlala ethangini amahora angama-24 kuya kwangama-48, okuyizikhathi ezingaba izikhathi ezingama-30 kuye kwezingama-50 kunesikhathi esivamile sokushiswa kwenjoloba. .
Amarola enjoloba amancane namancane manje aseguqulelwa kakhulu ekubeni i-vulcanization yamapuleti ecindezelwayo, aguqule ngokuphelele indlela evamile yokwenza amarola enjoloba.Eminyakeni yamuva, imishini yokubumba imijovo iye yasetshenziswa ukufaka isikhunta kanye ne-vacuum vulcanization, futhi isikhunta singavulwa futhi sivalwe ngokuzenzakalelayo.Izinga lemishini kanye ne-automation lithuthukiswe kakhulu, futhi isikhathi sokwenza i-vulcanization sifushane, ukusebenza kahle kokukhiqiza kuphezulu, kanye nekhwalithi yomkhiqizo yinhle.Ikakhulukazi uma usebenzisa umshini wokugcwalisa umjovo wenjoloba, izinqubo ezimbili zokubumba kanye ne-vulcanization zihlanganiswa zibe yinto eyodwa, futhi isikhathi singafinyezwa sibe yimizuzu emi-2 kuya kwemi-4, okuye kwaba isiqondiso esibalulekile sokuthuthukiswa kokukhiqizwa kwe-rubber roller.
Njengamanje, irabha ewuketshezi emelwe yi-polyurethane elastomer (PUR) ithuthuke ngokushesha ekukhiqizeni ama-roller enjoloba, futhi isivule indlela entsha yezinto ezibonakalayo kanye nenqubo yokuguquguquka kwayo.Yamukela ifomu lokuthulula ukuze isuse imisebenzi yokubumba eyinkimbinkimbi kanye nemishini emikhulu ye-vulcanization, okwenza kube lula kakhulu inqubo yokukhiqiza amarola enjoloba.Kodwa-ke, inkinga enkulu ukuthi isikhunta kufanele sisetshenziswe.Kuma-roller amakhulu enjoloba, ikakhulukazi emikhiqizweni ngayinye, izindleko zokukhiqiza zikhuphuka kakhulu, okuletha ubunzima obukhulu ekukhuthazeni nasekusetshenzisweni.
Ukuze uxazulule le nkinga, inqubo entsha ye-PUR yerabha roller ngaphandle kokukhiqiza isikhunta ivele eminyakeni yamuva.Isebenzisa i-polyoxypropylene ether polyol (TDIOL), i-polytetrahydrofuran ether polyol (PIMG) kanye ne-diphenylmethane diisocyanate (MDl) njengezinto zokusetshenziswa.Isabela ngokushesha ngemva kokuxubana nokunyakazisa, futhi ithululelwa ngobuningi kumongo wensimbi ozungezayo wenjoloba., Ibonakala ngesinyathelo ngesinyathelo ngenkathi ithela futhi iphulukisa, futhi ekugcineni kwakhiwa i-roller yerabha.Le nqubo ayifushane nje kuphela ngenqubo, iphezulu emishini kanye ne-automation, kodwa futhi iqeda isidingo sesikhunta esikhulu.Ingakhiqiza ama-roller enjoloba okucaciswa okuhlukahlukene namasayizi ngokuthanda, okunciphisa kakhulu izindleko.Sekuyiyona ndlela eyinhloko yokuthuthukiswa kwamarola erabha e-PUR.
Ngaphezu kwalokho, amarola enjoloba amancane asetshenziswa ekwenziweni kwemishini ye-automation yasehhovisi enerabha eyi-silicone ewuketshezi nawo athuthuka ngokushesha emhlabeni wonke.Ahlukaniswe abe izigaba ezimbili: ukwelapha ukushisa (LTV) kanye nokwelapha izinga lokushisa legumbi (RTV).Izinto ezisetshenziswayo nazo zihlukile ku-PUR engenhla, zakha olunye uhlobo lwefomu lokusakaza.Lapha, inkinga ebaluleke kakhulu indlela yokulawula nokunciphisa i-viscosity ye-rubber compound ukuze ikwazi ukugcina ingcindezi ethile kanye nesivinini se-extrusion.
