Ukwenziwa
Ukubumba irabha ngeroli ikakhulu kukuncamathisela irabha yokugquma kwisiseko sesinyithi, kubandakanya indlela yokusonga, indlela yokukhupha, indlela yokubumba, indlela yoxinzelelo lwenaliti kunye nendlela yokuhlaba. Okwangoku, iimveliso eziphambili zasekhaya kukuncamathisela ngoomatshini okanye ngesandla kunye nokubumba, kwaye uninzi lwamazwe angaphandle luye lwaqaphela ukuzenzekela koomatshini. Iirola zerabha ezinkulu neziphakathi ngokusisiseko ziveliswa ngokuprofayilisha i-extrusion, ukubumba ngokuqhubekayo ngefilimu ekhutshiweyo okanye ukubumba ngokuqhubekekayo ngeteyipu ekhutshiweyo. Kwangaxeshanye, kwinkqubo yokubumba, iinkcukacha, ubukhulu kunye nemilo yembonakalo zilawulwa ngokuzenzekelayo yi-microcomputer, kwaye ezinye zinokubunjwa ngendlela ye-extruder ye-engile yasekunene kunye ne-extrusion enemilo ekhethekileyo.
Indlela yokubumba ekhankanyiweyo apha ngasentla ayinakunciphisa kuphela amandla okusebenza, kodwa ikwasusa amaqamza anokubakho. Ukuze kuthintelwe i-roller yerabha ekuguquguqukeni ngexesha le-vulcanization kunye nokuthintela ukuveliswa kwamaqamza kunye neziponji, ngakumbi kwi-roller yerabha ebunjwe yindlela yokusonga, kufuneka kusetyenziswe indlela yokucinezela eguquguqukayo ngaphandle. Ngokwesiqhelo, umphezulu wangaphandle we-roller yerabha ugqunywa kwaye uvalwe ngeengqimba ezininzi zelaphu lekotoni okanye ilaphu le-nylon, uze ulungiswe kwaye ucinezelwe ngentambo yentsimbi okanye intambo yefayibha. Nangona le nkqubo sele yenziwe ngoomatshini, i-dressing kufuneka isuswe emva kwe-vulcanization ukuze yenze inkqubo "ye-cecal", eyenza kube nzima inkqubo yokuvelisa. Ngaphezu koko, ukusetyenziswa kwelaphu lokunxiba kunye nentambo yokujija kuncinci kakhulu kwaye ukusetyenziswa kuninzi.
Kwiirola zerabha ezincinci nezincinci, iinkqubo ezahlukeneyo zemveliso zingasetyenziswa, ezinje ngokupeyinta ngesandla, ukufaka indlwane yokukhupha, uxinzelelo lwe-injection, i-injection kunye nokuthulula. Ukuze kuphuculwe ukusebenza kakuhle kwemveliso, uninzi lweendlela zokubumba ngoku zisetyenziswa, kwaye ukuchaneka kuphezulu kakhulu kunendlela yokungabumba. Uxinzelelo lwe-injection, i-injection yerabha eqinileyo kunye nokuthulula irabha engamanzi ziye zaba zezona ndlela zibalulekileyo zemveliso.
Ukwanda kwe-Vulcanization
Okwangoku, indlela yokusebenzisa i-vulcanization yee-roller zerabha ezinkulu neziphakathi iseyi-vulcanization tank vulcanization. Nangona indlela yokusebenzisa i-flexible pressurization itshintshiwe, ayiphumi kumthwalo onzima wokuthutha, ukuphakamisa nokukhupha. Umthombo wobushushu be-vulcanization uneendlela ezintathu zokufudumeza: umphunga, umoya oshushu kunye namanzi ashushu, kwaye eyona iphambili isengumphunga. Ii-roller zerabha ezineemfuno ezikhethekileyo ngenxa yokudibana kwe-metal core nomphunga wamanzi zisebenzisa i-contact steam vulcanization, kwaye ixesha liya kwandiswe ngokuphindwe ka-1 ukuya kwezi-2. Ngokuqhelekileyo isetyenziselwa ii-roller zerabha ezinee-core zentsimbi ezingenanto. Kwii-roller zerabha ezikhethekileyo ezingenakusetyenziswa i-vulcanization ngetanki ye-vulcanization, amanzi ashushu ngamanye amaxesha asetyenziselwa i-vulcanization, kodwa unyango longcoliseko lwamanzi kufuneka lusonjululwe.
Ukuze kuthintelwe ukuba irabha kunye nesiseko sesinyithi zingahlukaniswa ngenxa yokuncipha okwahlukileyo komahluko wokuqhuba ubushushu phakathi kwerola yerabha kunye nesiseko serabha, i-vulcanization idla ngokusebenzisa indlela yokufudumeza kancinci kunye nokunyusa uxinzelelo, kwaye ixesha le-vulcanization lide kakhulu kunexesha le-vulcanization elifunekayo yirabha ngokwayo. . Ukuze kufezekiswe i-vulcanization efanayo ngaphakathi nangaphandle, kwaye kwenziwe i-thermal conductivity yesiseko sesinyithi kunye nerabha ifane, i-roller enkulu yerabha ihlala etankini iiyure ezingama-24 ukuya kuma-48, elimalunga namaxesha angama-30 ukuya kuma-50 exesha eliqhelekileyo le-vulcanization yerabha.
Iirola zerabha ezincinci nezincinci ngoku ziguqulwa kakhulu zibe yi-plate vulcanizing press molding vulcanization, nto leyo etshintsha ngokupheleleyo indlela yendabuko ye-vulcanization yeerola zerabha. Kwiminyaka yakutshanje, oomatshini bokubumba ngenaliti basetyenziselwe ukufaka ii-molds kunye ne-vacuum vulcanization, kwaye ii-molds zinokuvulwa kwaye zivalwe ngokuzenzekelayo. Umgangatho woomatshini kunye noozenzele uye waphucuka kakhulu, kwaye ixesha le-vulcanization lifutshane, ukusebenza kakuhle kwemveliso kuphezulu, kwaye umgangatho wemveliso ulungile. Ingakumbi xa kusetyenziswa umatshini we-rubber injection molding vulcanizing, iinkqubo ezimbini zokubumba kunye ne-vulcanization zidityaniswe zibe yinto enye, kwaye ixesha lingafinyezwa libe yimizuzu emi-2 ukuya kwemine, eye yaba yindlela ebalulekileyo yophuhliso lwemveliso ye-rubber roller.
Okwangoku, irabha engamanzi emelwe yi-polyurethane elastomer (PUR) iphuhlile ngokukhawuleza ekuvelisweni kweerola zerabha, kwaye ivule indlela entsha yokuguqula izinto kunye nenkqubo. Isebenzisa indlela yokuthulula ukuze isuse imisebenzi enzima yokubumba kunye nezixhobo ezinkulu ze-vulcanization, nto leyo eyenza kube lula kakhulu inkqubo yokuvelisa iirola zerabha. Nangona kunjalo, ingxaki enkulu kukuba kufuneka kusetyenziswe iimolds. Kwiirola zerabha ezinkulu, ingakumbi kwiimveliso nganye nganye, iindleko zokuvelisa zinyuswa kakhulu, nto leyo ezisa ubunzima obukhulu ekukhuthazeni nasekusetyenzisweni.
Ukuze kusonjululwe le ngxaki, kuye kwavela inkqubo entsha ye-PUR rubber roller ngaphandle kokuveliswa kwe-mold kwiminyaka yakutshanje. Isebenzisa i-polyoxypropylene ether polyol (TDIOL), i-polytetrahydrofuran ether polyol (PIMG) kunye ne-diphenylmethane diisocyanate (MDl) njengezinto eziluhlaza. Isabela ngokukhawuleza emva kokuxuba nokuxuba, kwaye igalelwa ngobuninzi kwi-metal roller yerabha ejikelezayo kancinci. , Iqatshelwa inyathelo ngenyathelo ngelixa igalelwa kwaye inyibilika, kwaye ekugqibeleni i-rubber roller yenziwa. Le nkqubo ayipheleli nje ekuqhubekeni, iphezulu kumatshini nakwi-automation, kodwa ikwasusa nesidingo se-buld ezinkulu. Ingavelisa ii-rubber roller zeenkcukacha ezahlukeneyo kunye nobukhulu ngokuthanda kwayo, nto leyo enciphisa kakhulu iindleko. Iye yaba yindlela ephambili yophuhliso lwee-PUR rubber roller.
Ukongeza, iirola zerabha ezincinci ezisetyenziswa ekwenzeni izixhobo ze-automation zeofisi ezinerabha ye-silicone engamanzi nazo zikhula ngokukhawuleza kwihlabathi liphela. Zahlulwe zibe ziindidi ezimbini: i-heating curing (LTV) kunye ne-room temperature curing (RTV). Izixhobo ezisetyenziswayo nazo zahlukile kwi-PUR engentla, zenza olunye uhlobo lwe-casting form. Apha, eyona ngxaki ibalulekileyo yindlela yokulawula nokunciphisa i-viscosity ye-rubber compound ukuze ikwazi ukugcina uxinzelelo oluthile kunye nesantya sokuphuma.
