Ukuxuba yenye yezona nyathelo zibalulekileyo nezintsonkothileyo ekucutshungulweni kwerabha. Kwakhona yenye yeenkqubo ezithambekele kakhulu ekutshintsheni komgangatho. Umgangatho werabha edityanisiweyo uchaphazela ngqo umgangatho wemveliso. Ke ngoko, kubaluleke kakhulu ukwenza umsebenzi olungileyo wokuxuba irabha.
Njengomxubi werabha, ungawenza njani umsebenzi olungileyo wokuxuba irabha? Ndicinga ukuba ukongeza ekuqondeni ulwazi oluyimfuneko lohlobo ngalunye lwerabha, njengeempawu zokuxuba kunye nolandelelwano lwedosi, kuyimfuneko ukusebenza nzima, ukucinga nzima, kunye nokuxuba irabha ngentliziyo. Kungale ndlela kuphela apho umnyibilikisi werabha ofanelekileyo ngakumbi ukhoyo.
Ukuqinisekisa umgangatho werabha exutyiweyo ngexesha lenkqubo yokuxuba, kufuneka kwenziwe la manqaku alandelayo:
1. Zonke iintlobo zezithako ezinedosi encinci kodwa enefuthe elihle mazixutywe ngokupheleleyo kwaye zixutywe ngokulinganayo, kungenjalo ziya kubangela ukutsha kwerabha okanye i-vulcanization engaphekwanga kakuhle.
2. Ukuxuba kufuneka kwenziwe ngokuhambelana nemigaqo yenkqubo yokuxuba kunye nolandelelwano lokutya.
3. Ixesha lokuxuba kufuneka lilawulwe ngokungqongqo, kwaye ixesha akufuneki libe lide kakhulu okanye lifutshane kakhulu. Kungale ndlela kuphela apho i-plasticity yerabha exutyiweyo ingaqinisekiswa khona.
4. Musa ukulahla isixa esikhulu se-carbon black kunye ne-fillers, kodwa zisebenzise zonke. Kwaye hlamba itreyi.
Kakade ke, zininzi izinto ezichaphazela umgangatho werabha edityanisiweyo. Nangona kunjalo, iimpawu ezithile kukusasazwa okungalinganiyo kwento edityanisiweyo, i-frost spray, i-scorch, njl.njl., ezinokubonwa ngamehlo.
Ukusasazwa okungalinganiyo kwe-compound agent Ukongeza kwiisuntswana ze-compound agent kumphezulu we-rubber compound, sika ifilimu ngemela, kwaye kuya kubakho iisuntswana ze-compound agent ezinobukhulu obahlukeneyo kwicandelo elinqamlezileyo le-rubber compound. I-compound ixutywe ngokulinganayo, kwaye icandelo ligudile. Ukuba ukusasazwa okungalinganiyo kwe-compound agent akusombululwa emva kokucocwa okuphindaphindiweyo, i-roller rubber iya kukhutshelwa. Ke ngoko, umxube werabha kufuneka ulandele ngokungqongqo imigaqo yenkqubo ngexesha lokusebenza, kwaye ngamanye amaxesha, thatha ifilimu kuzo zombini iziphelo kunye nombindi we-roller ukuze ubone ukuba i-compound agent isasazeke ngokulinganayo na.
Ukuqandusela, ukuba akuyongxaki yoyilo lwefomyula, oko kubangelwa kukulandelelana okungafanelekanga komthamo ngexesha lenkqubo yokuxuba, okanye ukuxubana okungalinganiyo kunye nokuhlanganiswa kwe-compounding agent. Ke ngoko, kuyimfuneko ukulawula ngokungqongqo inkqubo yokuxuba ukuze kuthintelwe ukwenzeka kweziganeko ezinjalo.
I-Scorch yenye yezona ngxaki zibalulekileyo kwinkqubo yokuxuba. Emva kokuba izinto zerabha zitshile, umphezulu okanye inxalenye yangaphakathi inee-rubber particles eziphekiweyo nge-elastic. Ukuba i-scorch incinci, ingasombululwa ngendlela ye-thin pass. Ukuba i-scorch imbi kakhulu, izinto zerabha ziya kukhutshelwa. Ngokwembono yezinto zenkqubo, i-scorch ye-rubber compound ichaphazeleka kakhulu bubushushu. Ukuba ubushushu be-rubber compound buphezulu kakhulu, i-raber eluhlaza, i-vulcanizing agent kunye ne-accelerator ziya kusabela ngexesha lenkqubo yokuxuba, oko kukuthi, i-scorch. Kwiimeko eziqhelekileyo, ukuba ubungakanani berabha ngexesha lokuxuba bukhulu kakhulu kwaye ubushushu be-roller buphezulu kakhulu, ubushushu berabha buya kwanda, okubangela i-scorch. Kakade ke, ukuba ulandelelwano lokutya alufanelekanga, ukongezwa ngaxeshanye kwe-vulcanizing agent kunye ne-accelerator nako kuya kubangela i-scorch ngokulula.
Ukuguquguquka kobulukhuni nako yinto ebalulekileyo echaphazela umgangatho we-rubber compound. Ii-compounds ezinobulukhuni obufanayo zihlala zixutywe nobunzima obahlukeneyo, kwaye ezinye zikude kakhulu. Oku kungenxa yokungaxutywanga ngokulinganayo kwe-rubber compound kunye nokusasazeka kakubi kwe-compound agent. Kwangaxeshanye, ukongeza i-carbon black encinci okanye engaphezulu kuya kubangela ukuguquguquka kobulukhuni be-rubber compound. Kwelinye icala, ubunzima obungachanekanga be-compound agent buya kubangela ukuguquguquka kobulukhuni be-rubber compound. Njengokongezwa kwe-vulcanizing agent kunye ne-accelerator carbon black, ubunzima be-rubber compound buya kwanda. I-softener kunye ne-rabber eluhlaza ziyalinganiswa ngakumbi, kwaye i-carbon black incinci, kwaye ubunzima be-rubber compound buba ncinci. Ukuba ixesha lokuxuba lide kakhulu, ubunzima be-rubber compound buya kuncipha. Ukuba ixesha lokuxuba lifutshane kakhulu, i-compound iya kuqina. Ke ngoko, ixesha lokuxuba akufuneki libe lide kakhulu okanye lifutshane kakhulu. Ukuba ukuxuba kukude kakhulu, ukongeza ekunciphiseni ubulukhuni berabha, amandla okutsalwa kwerabha aya kuncipha, ubude xa ikhefu liza kwanda, kwaye ukumelana nokwaluphala kuya kuncipha. Kwangaxeshanye, kwandisa amandla okusebenza kwabasebenzi kwaye kudla amandla.
Ngoko ke, ukuxuba kufuneka kuphela kukwazi ukusasaza ngokupheleleyo ii-arhente ezahlukeneyo zokudibanisa kwi-compound yerabha, nokuqinisekisa iipropati zomzimba nezoomatshini ezifunekayo kunye neemfuno ze-calendar, extrusion kunye neminye imisebenzi yenkqubo.
Njengomxubi werabha ofanelekileyo, akapheleli nje ekubeni nemvakalelo enamandla yoxanduva, kodwa kufuneka azazi iirabha ezahlukeneyo ezingavuthwanga kunye nezinto eziluhlaza. Oko kukuthi, kungekuphela nje ukuqonda imisebenzi kunye neempawu zazo, kodwa nokuba akwazi ukubiza amagama azo ngokuchanekileyo ngaphandle kweelebheli, ngakumbi kwiikhompawundi ezinembonakalo efanayo. Umzekelo, i-magnesium oxide, i-nitric oxide kunye ne-calcium hydroxide, i-carbon black engagugiyo kakhulu, i-carbon black ekhutshwa ngokukhawuleza kunye ne-semi-reinforced carbon black, kunye ne-nitrile-18 yasekhaya, i-nitrile-26, i-nitrile-40 njalo njalo.
