Ukwakha
Ukubumba irabha nge-roller ikakhulukazi kuhloswe ukunamathisela irabha yokumboza enkabeni yensimbi, okuhlanganisa indlela yokugoqa, indlela yokukhipha, indlela yokubumba, indlela yokucindezela komjovo kanye nendlela yokujova. Njengamanje, imikhiqizo yasekhaya eyinhloko ukunamathisela nokubopha ngomshini noma ngesandla, futhi amazwe amaningi angaphandle asethole ukuzenzekela ngomshini. Ama-roller erabha amakhulu naphakathi akhiqizwa ngokufaka iphrofayili, ukubumba ngokunamathisela ngefilimu ekhishwe noma ukubumba ngokugoqa okuqhubekayo ngetheyiphu ekhishwayo. Ngesikhathi esifanayo, enkambisweni yokubumba, imininingwane, ubukhulu kanye nesimo sokubukeka kulawulwa ngokuzenzakalelayo yi-microcomputer, futhi amanye angabunjwa ngendlela ye-extruder ye-angle kwesokudla kanye ne-extrusion enomumo okhethekile.
Indlela yokubumba eshiwo ngenhla ayikwazi nje ukunciphisa amandla okusebenza, kodwa futhi isuse amabhamuza angaba khona. Ukuze kuvinjelwe i-roller yerabha ekuguquguqukeni ngesikhathi se-vulcanization nokuvimbela ukukhiqizwa kwamabhamuza neziponji, ikakhulukazi i-roller yerabha ebunjwe yindlela yokusonga, indlela yokucindezela eguquguqukayo kumele isetshenziswe ngaphandle. Ngokuvamile, ubuso bangaphandle be-roller yerabha bugoqwa futhi buboshwe ngezendlalelo eziningana zendwangu yekotini noma indwangu ye-nylon, bese buqiniswa futhi bucindezelwe ngentambo yensimbi noma intambo yefayibha. Nakuba le nqubo isivele yenziwe ngomshini, i-dressing kumele isuswe ngemuva kwe-vulcanization ukuze kwakhiwe inqubo "ye-cecal", okwenza inqubo yokukhiqiza ibe nzima. Ngaphezu kwalokho, ukusetshenziswa kwendwangu yokugqoka kanye nentambo yokugoqa kulinganiselwe kakhulu futhi ukusetshenziswa kukhulu.
Kuma-roller enjoloba amancane nancane, kungasetshenziswa izinqubo ezahlukahlukene zokukhiqiza, njengokuchibiyela ngesandla, ukufaka izidleke zokukhipha, ukucindezela ngomjovo, ukufaka kanye nokuthulula. Ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza, izindlela eziningi zokubumba sezisetshenziswa manje, futhi ukunemba kuphakeme kakhulu kunokwendlela yokungakhiqizi. Ukucindezela ngomjovo, ukufaka injoloba eqinile kanye nokuthulula injoloba ewuketshezi sekuyizindlela zokukhiqiza ezibaluleke kakhulu.
Ukuvuvukala
Njengamanje, indlela ye-vulcanization yama-roller enjoloba amakhulu naphakathi iseyi-vulcanization yethangi le-vulcanization. Nakuba imodi yokucindezela eguquguqukayo ishintshiwe, ayikaphumi emthwalweni onzima wokuthutha, ukuphakamisa nokukhipha impahla. Umthombo wokushisa we-vulcanization unezindlela ezintathu zokushisa: umusi, umoya oshisayo namanzi ashisayo, kanti okuyinhloko kuseyisisi. Ama-roller enjoloba anezidingo ezikhethekile ngenxa yokuxhumana kwengaphakathi lensimbi nomhwamuko wamanzi asebenzisa i-vulcanization engaqondile ye-steam, futhi isikhathi sizokwelulwa izikhathi ezingu-1 kuya kwezingu-2. Ngokuvamile isetshenziselwa ama-roller enjoloba anezinsika zensimbi ezingenalutho. Kuma-roller enjoloba akhethekile angenakukwazi ukuvunguzwa ngethangi le-vulcanization, amanzi ashisayo ngezinye izikhathi asetshenziselwa ukuvunguza, kodwa ukwelashwa kokungcola kwamanzi kudinga ukuxazululwa.
Ukuze kuvinjelwe irabha kanye ne-metal core ukuthi ingahlukaniswa ngenxa yokuncipha okuhlukile komehluko wokuqhuba ukushisa phakathi kwe-rabha roller kanye ne-rabha core, i-vulcanization ivame ukusebenzisa indlela yokushisa kancane kanye nokwandisa ingcindezi, futhi isikhathi se-vulcanization side kakhulu kunesikhathi se-vulcanization esidingwa yi-rabha uqobo. . Ukuze kufezwe i-vulcanization efanayo ngaphakathi nangaphandle, futhi kwenziwe i-thermal conductivity ye-metal core kanye ne-rabha ifane, i-rabha roller enkulu ihlala ethangini amahora angama-24 kuya kwangu-48, okuphindwe cishe izikhathi ezingama-30 kuya kwangu-50 kunesikhathi esivamile se-rubber vulcanization.
Amarola enjoloba amancane namancane manje aguqulwa kakhulu abe yi-plate vulcanizing press molding vulcanization, okushintsha ngokuphelele indlela yendabuko ye-vulcanization yamarola enjoloba. Eminyakeni yamuva nje, imishini yokubumba ngomjovo isetshenziswe ukufaka isikhunta kanye ne-vacuum vulcanization, futhi isikhunta singavulwa futhi sivalwe ngokuzenzakalelayo. Izinga lokusebenzisa imishini kanye nokwenza izinto ngokuzenzakalela lithuthukisiwe kakhulu, futhi isikhathi se-vulcanization sifushane, ukusebenza kahle kokukhiqiza kuphezulu, futhi ikhwalithi yomkhiqizo inhle. Ikakhulukazi uma kusetshenziswa umshini wokubumba ngomjovo wenjoloba, izinqubo ezimbili zokubumba kanye ne-vulcanization zihlanganiswa zibe yinto eyodwa, futhi isikhathi singafinyezwa sibe yimizuzu emi-2 kuya kwemine, okuye kwaba yisiqondiso esibalulekile sokuthuthukiswa kokukhiqizwa kwe-rubber roller.
Njengamanje, irabha ewuketshezi emelelwa yi-polyurethane elastomer (PUR) ithuthuke ngokushesha ekukhiqizweni kwama-roller erabha, futhi ivule indlela entsha yezinto zokwakha kanye nenqubo yokuguqula. Isebenzisa ifomu lokuthulula ukuze kuqedwe imisebenzi yokubumba eyinkimbinkimbi kanye nemishini emikhulu ye-vulcanization, okwenza kube lula kakhulu inqubo yokukhiqiza ama-roller erabha. Kodwa-ke, inkinga enkulu ukuthi isikhunta kumele sisetshenziswe. Kuma-roller amakhulu erabha, ikakhulukazi emikhiqizweni ngayinye, izindleko zokukhiqiza zikhuphuka kakhulu, okuletha ubunzima obukhulu ekukhushulweni nasekusetshenzisweni.
Ukuze kuxazululwe le nkinga, inqubo entsha ye-PUR rubber roller ngaphandle kokukhiqizwa kwesikhunta ivele eminyakeni yamuva nje. Isebenzisa i-polyoxypropylene ether polyol (TDIOL), i-polytetrahydrofuran ether polyol (PIMG) kanye ne-diphenylmethane diisocyanate (MDl) njengezinto zokusetshenziswa. Isabela ngokushesha ngemva kokuxuba nokuxuba, futhi ithululelwa ngobuningi enkabeni yensimbi ye-rubber roller ejikelezayo kancane kancane. , Iyenzeka isinyathelo ngesinyathelo ngenkathi ithululwa futhi iqiniswa, futhi ekugcineni i-rubber roller iyakhiwa. Le nqubo ayigcini nje ngokusebenza isikhathi esifushane, inamandla okusebenzisa imishini kanye nokwenza izinto ngokuzenzakalela, kodwa futhi iqeda isidingo sesikhunta esikhulu. Ingakhiqiza ama-rubber roller anezincazelo ezahlukene kanye nobukhulu ngokuthanda kwayo, okunciphisa kakhulu izindleko. Sekuyisiqondiso esiyinhloko sokuthuthukiswa kwama-rubber roller e-PUR.
Ngaphezu kwalokho, ama-roller enjoloba amancane asetshenziswa ekwakhiweni kwemishini yokwenza izinto ngokuzenzakalela ehhovisi ngenjoloba ye-silicone ewuketshezi nawo athuthuka ngokushesha emhlabeni wonke. Ahlukaniswe ngezigaba ezimbili: ukupholisa ukushisa (i-LTV) kanye nokupholisa izinga lokushisa legumbi (i-RTV). Imishini esetshenziswayo nayo ihlukile ku-PUR engenhla, yakha olunye uhlobo lohlobo lokukhipha. Lapha, inkinga ebaluleke kakhulu ukuthi ungalawula futhi unciphise kanjani i-viscosity yenhlanganisela yenjoloba ukuze ikwazi ukugcina ingcindezi ethile kanye nesivinini sokukhipha.
