Irabha sisixhobo esisetyenziswa kakhulu nesiguquguqukayo esisetyenziswa xa kusenziwa iimveliso ezahlukeneyo, eziquka iibhanti ezilastiki, izihlangu, iminqwazi yokuqubha, kunye nemibhobho.Enyanisweni, ukuveliswa kwamatayara ezithuthi kudla malunga nesiqingatha sayo yonke irabha eveliswayo.Ngenxa yokubaluleka kwayo, kuyafaneleka ukuhlola inkqubo yokudala irabha kunye nemvelaphi yayo.Eli nqaku liza kunika ingqalelo ukwazisa malunga nemvelaphi yerabha,indlela yokwenza irabha,izicelo zerabha, uhlobo lwerabhakwayekutheni ukhetha irabhanjengemathiriyeli ekrwada yemveliso.
Imvelaphi yerabha
Ngaphezu kwewaka leminyaka, abantu bebesebenzisa iimpawu zerabha ezomeleleyo nezibhetyebhetye ukwenza izinto ezahlukahlukeneyo.Ekuqaleni ithathwe kwimathiriyeli yendalo, kodwa ngenxa yerabha iye yaduma ngakumbi kunye nokunyuka kwemfuno kukhokelela ekubeni abantu bathande ukwenza irabha kwiilebhu ezinokuvelisa irabha enophawu oluninzi.Kule mihla, uninzi lwerabha esiyisebenzisayo iveliswa ngokwenziwa.
Yenziwa Njani Irabha Yendalo
Iindidi ezahlukeneyo zeerabha ezenziweyo zisebenza imisebenzi eyahlukeneyo kwaye ke, iindlela zokuvelisa zinokwahluka kakhulu.Endaweni yokuxhomekeka kwimithombo yendalo, ezi rubber zenziwe ngeenkqubo zekhemikhali ezifana ne-polymerization.Izinto eziqhelekileyo zomthombo ezifana namalahle, i-oyile, kunye ne-hydrocarbons ziyasulungekiswa ukwenza i-naphtha.INaphtha iye ixutywe nerhasi yendalo ukuze yenze imon ephinda igalelwe amatyathanga epolymer kusetyenziswa umphunga kunye nevulcanization ukuvelisa irabha.
Inkqubo yerabha
1.Ukudibanisa
Ukubandakanya izongezo zekhemikhali kwisiseko serabha kunokuvelisa iikhompawundi zerabha ezineempawu eziphuculweyo.Ezi khemikhali zinokuzinzisa ubume bepolymer okanye zonyuse amandla erabha.Ukongeza, inkqubo yokudibanisa ngamanye amaxesha inokunyusa ukuqina kwerabha, okukhokelela kwixabiso eliphantsi lokugqibela.
2.Ukuxuba
Kwinkqubo efana nokudibanisa, izongezo zixutywe kunye nerubha kweli nqanaba.Ukuqinisekisa ukuhanjiswa okufanelekileyo kwezithako kunye nokuthintela ukushisa, abaxube abanobuchule benza le nkqubo kwizigaba ezimbini.Okokuqala, abantu baya kulungiselela i-masterbatch equlethe izongezo ezifana nekhabhoni emnyama.Yakuba ipholile irabha, bazisa imichiza efunekayo ukuze ivulcanization.
3.Ukubunjwa
Abavelisi banokusebenzisa iindlela ezahlukeneyo zokubunjwa ezinje ngokutyabeka, ukukhupha, ukuphosa, ukulinganisa, kunye nokubumba ukuvelisa uluhlu olubanzi lweemveliso.Ukukhethwa kobuchule bokubumba kuxhomekeke kwiimfuno ezithile zemveliso yokugqibela.
4.Ukuhlanjululwa
Ukomeleza ukuqina kunye nokomelela kwayo, irabha ifumana unyango olushushu olubizwa ngokuba yivulcanization.Le nkqubo ibandakanya ukufudumeza irabha, ngokuphindaphindiweyo ngesulfure, ukudala izibophelelo ezongezelelweyo phakathi kwama-molecule, okwenza ukuba bangabikho ukuhlukana.Ukulandela i-vulcanization, naziphi na iziphene ziyasuswa, kwaye irabha ibunjwe okanye ibunjwe kwimveliso efunwayo.Irabha ihlala iyimveliso ebalulekileyo eneendlela ezahlukeneyo zokusebenza, kwaye iRuicheng ibonelela ngoluhlu olubanzi lweemveliso zerabha ezikumgangatho ophezulu, kubandakanya ukukhwelana, itywina, kunye ne-extrusions.
Isicelo serabha
Umzi:Irabha iqhele ukusetyenziswa ekuveliseni izihlangu, iibhutsi, kunye nezinye izihlangu ngenxa yokuqina kwayo kunye neempawu zokunganyangeki kwamanzi.
Izithuthi: Irabha isetyenziswa kumacandelo emoto ahlukeneyo anje ngeehosi, iibhanti, iibhutsi, kunye nezinyusi ze-injini zokudambisa ukungcangcazela kunye nokufunxa ukothuka.Ingakumbi amatayara, irabha iyinxalenye ebalulekileyo yokwenziwa kwamatayara eemoto, eebhayisekile nezinye izithuthi.
Izixhobo zonyango: Ngenxa yeempawu ezininzi ezintle zerabha, imimandla yezonyango kulo lonke ishishini ithatha imathiriyeli kwiintlobo ezahlukeneyo zezicelo.Iingcali zonyango, kubandakanywa iindlebe, impumlo, kunye neengcali zomqala, i-cardiology, i-oncology, i-ophthalmology, utyando lweplastiki, kunye notyando jikelele luguqukela kwirabha ye-silicone elulwelo kunye nokubumba irabha yezonyango ukuze kusetyenziswe enye kunye nezixhobo zonyango ezinokuphinda zisetyenziswe.
Kwangaxeshanye, iRubber isetyenziswa ekwenzeni izixhobo zonyango ezifana neeglavu, iityhubhu, kunye netywina ngenxa ye-biocompatibility yayo kunye nokuguquguquka.
Iimpahla zeMidlalo: Irabha isetyenziselwa ukuveliswa kwezixhobo zemidlalo ezifana neebhola, ukubamba, kunye ne-padding ngenxa ye-elasticity kunye nokuchasana kwempembelelo.
Iintlobo eziqhelekileyo zeerabha
Irabha yendalo
Irabha yendalo ifunyanwa ngokukhupha incindi engamanzi, ebizwa ngokuba yilatex, kwiindidi ezahlukeneyo zemithi, kunye nomthi weHevea brasiliensis ungowona mthombo uphambili.Inkqubo yokuqokelela i-latex ibandakanya ukusika kwi-bark kunye nokuqokelela i-sap kwiikomityi, inkqubo eyaziwa ngokuba yi-tapping.Ukuthintela ukuqina, i-ammonia yongezwa, ilandelwa yi-asidi ukukhupha irabha ngokudibanisa, okuthatha malunga neeyure ze-12.Umxube ugqithiswa ngee-rollers ukususa amanzi amaninzi, kwaye iileya zerubha zomiswa ngokuzixhoma phezu kwee-racks kwii-smokehouses okanye zomiswe ngomoya.
Irabha yokwenziwa
Izazinzulu zaseJamani zenze irabha yokwenziwa ngexesha leMfazwe Yehlabathi I ngenxa yokunqongophala kwemithombo yerabha yendalo.Ngelixa ekuqaleni ikumgangatho ophantsi kunerabha yendalo, irabha yokwenziwa iye yahambela phambili ngokuhamba kwexesha ngophando nophuhliso.Kule mihla, irabha yokwenziwa yomelele kwaye ithembekile njengomlingani wayo wendalo.Umahluko ophambili phakathi kwerabha yokwenziwa kunye neyendalo ilele kwinto yokuba irabha yokwenziwa iveliswa ngokudibanisa iimolekyuli zepolymer kwilebhu.Ngoku uninzi lwabavelisi bathanda ukusebenzisa irabha eyenziweyo.
Izinto eziluncedo zerabha
Ukuguquguquka kunye nokuguquguquka: I-Rubber iyaziwa ngokunyuka kwayo okuphezulu kunye nokuguquguquka, ukuyivumela ukuba ikhubazeke phantsi koxinzelelo kwaye ibuyele kwimo yayo yokuqala xa uxinzelelo lususiwe.Le propati yenza irabha ilungele ukusetyenziswa apho ukuqina kunye nokuguquguquka kuyadingeka, njengamatayara, itywina, kunye nezixhobo zokuxilisa.
Ukumelana nokunxiba kunye nokukrazula: Irabha ibonisa ukuxhathisa okuphezulu kwi-abrasion, ukuguga, kunye nokukrazula, iyenza yomelele kwaye ihlale ixesha elide.Lo mhlaba wenza irabha ilungele usetyenziso olubandakanya ukukhuhlana rhoqo kunye nokuvezwa kokusingqongileyo okurhabaxa, okufana namabhanti okuhambisa, imibhobho yemizi-mveliso, kunye nezixhobo zemoto.
Unciphiso lwengxolo: Irabha inokudambisa ngokufanelekileyo ukungcangcazela kunye nokunciphisa ingxolo, iyenze ilungele ukusetyenziswa kwizicelo apho ukunciphisa ingxolo kubalulekile, njengakumalungu eemoto nakwizinto zokwakha.
Ukufunxa ukothuka: Irabha ineempawu ezibalaseleyo zokufunxa umothuko, nto leyo eyenza ukuba ilungele ukusetyenziswa kwiimveliso ezinjengezihlangu, izixhobo zemidlalo, kunye neendawo zokuxhoma zokungcangcazela.
Ezi zibonelelo zenza irabha ibe yimathiriyeli exabisekileyo kuluhlu olubanzi lwemizi-mveliso, kubandakanya iimoto, ezokwakha, ezombane, ukhathalelo lwempilo, kunye nempahla yabathengi.
Isishwankathelo
Eli nqaku lihlolisise iimpawu zerabha, likhanyise imvelaphi yalo, umfaki-sicelo kunye neenzuzo, kwaye lingenise irabha eqhelekileyo ngeendlela ezahlukeneyo ezinokuthi zithathe kwizicelo zoshishino.sithemba ukuba eli nqaku likuncede ukuba ubone ukuba zininzi kangakanani ukusetyenziswa kwerabha kukho ngokwenene.Ngerabha, amathuba angenamkhawulo.Ukuba ufuna ukwazi ngakumbi,nceda uqhagamshelane nathi!
