Uninzi lweeyunithi kunye neefektri zisebenzisa imixube yerabha evulekileyo.Olona phawu lwayo lukhulu kukuba lunokuguquguquka okukhulu kunye nokuhamba, kwaye lufaneleke ngakumbi ukuxutywa kweentlobo ezahlukeneyo zerabha, irabha eqinile, irabha yesipontshi, njl.
Xa uxutywa nelitye elivulekileyo, umyalelo we-dosing ubaluleke kakhulu.Kwiimeko eziqhelekileyo, irabha eluhlaza ifakwe kwi-gap yomqulu ecaleni kwelinye icala levili elicinezelayo, kwaye umgama we-roll ulawulwa malunga ne-2mm (thatha i-rubber mixer ye-intshi eyi-14 njengomzekelo) kwaye uqhube imizuzu emi-5.I-glue eluhlaza yenziwe ifilimu egudileyo kwaye ingenasiphelo, ehlanganiswe kwi-roller yangaphambili, kwaye kukho inani elithile leglue eliqokelelweyo kwi-roller.I-akhawunti yerabha eqokelelweyo malunga ne-1/4 yexabiso elipheleleyo lerabha eluhlaza, kwaye emva koko i-agent anti-aging kunye ne-accelerators yongezwa, kwaye i-rubber i-tamped amaxesha amaninzi.Injongo yale nto kukwenza i-antioxidant kunye ne-accelerator ihlakazeke ngokulinganayo kwiglue.Ngexesha elifanayo, ukongezwa kokuqala kwe-antioxidant kunokuthintela ukuguga kwe-thermal okwenzeka ngexesha lokuxuba irabha ephezulu.Kwaye ezinye i-accelerator zinefuthe leplastiki kwi-rubber compound.I-zinc oxide yongezwa emva koko.Xa ufaka i-carbon black, ixabiso elincinci kakhulu kufuneka lifakwe ekuqaleni, kuba ezinye iirubha eziluhlaza ziya kuphuma kwi-roll ngokukhawuleza ukuba i-carbon black ifakwe.Ukuba kukho naluphi na uphawu lwe-off-roll, yeka ukongeza i-carbon emnyama, kwaye wongeze i-carbon emnyama emva kokuba irabha isongelwe kwi-roller kakuhle kwakhona.Kukho iindlela ezininzi zokongeza i-carbon black.Ngokukodwa zibandakanya: 1. Yongeza i-carbon black kunye nobude bokusebenza be-roller;2. Yongeza i-carbon black phakathi kwe-roller;3. Yongeza kufutshane nesiphelo sebhaffle.Ngokombono wam, iindlela ezimbini zokugqibela zokongeza i-carbon black zikhethwayo, oko kukuthi, kuphela inxalenye ye-degumming isuswe kwi-roller, kwaye akunakwenzeka ukususa yonke i-roller.Emva kokuba i-rubber compound ikhutshwe kwi-roll, i-carbon black icinezeleka ngokulula ibe yi-flakes, kwaye akulula ukusabalalisa emva kokuqengqeleka kwakhona.Ngokukodwa xa uxova irabha eqinile, isulfure icinezelwe kwiiflakes, okunzima kakhulu ukusabalalisa kwirabha.Akukho ndawo yokucokisa okanye ebhityileyo inokutshintsha indawo etyheli “yepokotho” ekhoyo kwifilimu.Ngamafutshane, xa ufaka i-carbon black, yongeza ngaphantsi nangaphezulu rhoqo.Musa ukuthatha inkathazo yokugalela yonke i-carbon black kwi-roller.Isigaba sokuqala sokongeza i-carbon black yithuba elikhawulezayo "lokutya".Musa ukufaka into yokuthambisa ngeli xesha.Emva kokongeza isiqingatha sekhabhoni emnyama, yongeza isiqingatha se-softener, esinokukhawuleza "ukutya".Esinye isiqingatha se-softener songezwa kunye ne-carbon black eseleyo.Kwinkqubo yokongeza i-powder, umgama we-roll kufuneka uhlaziywe ngokuthe ngcembe ukuze ugcine i-rubber edibeneyo phakathi koluhlu olufanelekileyo, ukwenzela ukuba i-powder ingene ngokwemvelo kwi-rubber kwaye ingaxutywa kunye ne-rubber ukuya kwinqanaba eliphezulu.Kule nqanaba, kunqatshelwe ngokungqongqo ukusika ummese, ukwenzela ukuba ungachaphazeli umgangatho we-rubber compound.Kwimeko ye-softener eninzi kakhulu, i-carbon black kunye ne-softener nayo inokudibaniswa kwifom yokunamathisela.Iasidi ye-Stearic akufuneki idityaniswe kwangoko kakhulu, kulula ukuyibangela ukuqengqeleka, kungcono ukuyidibanisa xa kusekho ikhabhoni emnyama kumqulu, kwaye i-ejenti ye-vulcanizing kufuneka yongezwe kamva.Ezinye i-vulcanizing agents zongezwa xa kusekho i-carbon black encinci kwi-roller.Okufana ne-agent ye-DCP ephazamisayo.Ukuba yonke i-carbon black idliwe, i-DCP iya kufudunyezwa kwaye inyibilike ibe lulwelo, oluya kuwela kwi-tray.Ngale ndlela, inani leejenti ze-vulcanizing kwi-compound liya kuncitshiswa.Ngenxa yoko, umgangatho we-rubber compound uyachaphazeleka, kwaye kunokwenzeka ukuba kubangele i-vulcanization engaphekwanga.Ngoko ke, i-agent ye-vulcanizing kufuneka yongezwe ngexesha elifanelekileyo, kuxhomekeke kwiindidi.Emva kokuba zonke iintlobo zee-agent ezixutywayo zongezwa, kuyimfuneko ukuqhubela phambili ukujika ukwenza i-rubber compound ixutywe ngokulinganayo.Ngokuqhelekileyo, kukho "iimela ezisibhozo", "iingxowa ezinxantathu", "i-rolling", "i-tongs ezincinci" kunye nezinye iindlela zokujika.
"Iimela ezisibhozo" zisika iimela kwi-angle ye-45 ° ecaleni kwendlela ehambelanayo ye-roller, amaxesha amane kwicala ngalinye.Iglue eseleyo ijijekile i-90 ° kwaye yongezwa kwi-roller.Injongo kukuba izinto zerubha zigqitywe kwiindlela ezithe tye kunye nezithe tye, ezihambelana nokuxuba okufanayo."Isikhwama esingunxantathu" yingxowa yeplastiki eyenziwe kunxantathu ngamandla e-roller."I-Rolling" kukusika imela ngesandla esinye, ukugoqa izinto zerabha kwi-cylinder ngesinye isandla, uze uyifake kwi-roller.Injongo yale nto kukwenza i-rubber compound ixutywe ngokulinganayo.Nangona kunjalo, "isikhwama senxantathu" kunye "ne-rolling" ayihambisani nokutshatyalaliswa kobushushu bezinto zerabha, ekulula ukubangela ukutshisa, kunye nomsebenzi onzima, ngoko ke ezi ndlela zimbini akufanele zikhuthazwe.Ixesha lokuguqula i-5 ukuya kwimizuzu emi-6.
Emva kokuba i-compound yerabha inyibilikile, kuyimfuneko ukunciphisa i-rubber compound.Ukuziqhelanisa kubonakalise ukuba ikhompawundi yokudlula ebhityileyo iyasebenza kakhulu ekusasazweni kwearhente edibanisayo kwikhompawundi.Indlela yokupasa encinci kukulungelelanisa umgama we-roller ukuya kwi-0.1-0.5 mm, ubeke izinto zerabha kwi-roller, kwaye uyivumele iwele kwi-tray yokutya ngokwemvelo.Emva kokuwa, vula izinto zerabha nge-90 ° kwi-roller ephezulu.Oku kuphinda-phindwe ka-5 ukuya kwi-6 amaxesha.Ukuba ubushushu bezinto zerabha buphezulu kakhulu, misa ipasi elibhityileyo, kwaye ulinde irubha ukuba iphole ngaphambi kokuba ucuthe ukuthintela izinto zerabha ukuba zingatsha.
Emva kokuba kugqitywe ukupasa okuncinci, phumla umgama we-roll ukuya kwi-4-5mm.Ngaphambi kokuba impahla yerabha ilayishwe emotweni, iqhekeza elincinci lerubha liyakrazulwa kwaye lifakwe kwii-roller.Injongo kukukhupha umgama wokuqengqeleka, ukwenzela ukuba kuthintelwe umatshini wokuxuba irabha ukuba unganyanzelwa phantsi ngamandla amakhulu kwaye wonakalise izixhobo emva kokuba ubuninzi bezinto zerabha budliwe kwi-roller.Emva kokuba impahla ye-rubber ilayishwe emotweni, kufuneka idlule kwi-gap roll kanye, uze uyifake kwi-roll yangaphambili, uqhubeke uyijika kwi-2 ukuya kwi-3 imizuzu, kwaye uyikhuphe kwaye uyipholise ngexesha.Ifilimu i-80 cm ubude, i-40 cm ububanzi kunye ne-0.4 cm ubukhulu.Iindlela zokupholisa ziquka ukupholisa kwendalo kunye nokupholisa itanki yamanzi abandayo, ngokuxhomekeke kwiimeko zeyunithi nganye.Ngexesha elifanayo, kuyimfuneko ukuphepha ukudibanisa phakathi kwefilimu kunye nomhlaba, isanti kunye nolunye ukungcola, ukwenzela ukuba ungachaphazeli umgangatho we-rubber compound.
Kwinkqubo yokuxuba, umgama we-roll kufuneka ulawulwe ngokungqongqo.Ubushushu obufunekayo ekuxutyweni kweerubha eziluhlaza ezahlukeneyo kunye nokuxutywa kobunzima obuhlukeneyo buhluke, ngoko ke ukushisa kwe-roller kufuneka kuqhutywe ngokwemeko ethile.
Abanye abasebenzi bokuxuba irabha banemibono emibini elandelayo engalunganga: 1. Bacinga ukuba ixesha elide lokuxuba, umgangatho ophezulu werabha.Oku akunjalo ekusebenzeni, ngenxa yezizathu ezichazwe ngasentla.2. Kukholelwa ukuba ngokukhawuleza inani leglue eliqokelelwe ngaphezu kwe-roller liyongezwa, ngokukhawuleza isantya sokuxuba siya kuba.Enyanisweni, ukuba akukho glue eqokelelweyo phakathi kwee-roller okanye iglue eqokelelweyo incinci kakhulu, i-powder iya kucinezelwa ngokulula kwiiflakes kwaye iwele kwi-tray yokutya.Ngaloo ndlela, ngaphezu kokuchaphazela umgangatho we-rubber edibeneyo, i-tray yokutya kufuneka ihlambuluke kwakhona, kwaye i-powder ewayo yongezwa phakathi kwee-roller, ephindaphinda kaninzi, eyandisa kakhulu ixesha lokuxuba kunye nokwandisa umsebenzi. ubunzulu.Ngokuqinisekileyo, ukuba ukuqokelela kweglue kuninzi kakhulu, isantya sokuxuba somgubo siya kuncipha.Ingabonwa ukuba ukuqokelela okuninzi okanye okuncinci kweglue akuthandeki ukuxuba.Ngoko ke, kufuneka kubekho umlinganiselo othile weglue eqokelelweyo phakathi kwee-roller ngexesha lokuxuba.Ngexesha lokuxubha, kwelinye icala, i-powder ifakwe kwi-glue ngesenzo samandla omatshini.Ngenxa yoko, ixesha lokuxuba lifutshane, amandla omsebenzi ayancipha, kwaye umgangatho we-rubber compound ulungile.
