Irabha iyinto esetshenziswa kakhulu futhi evumelana nezimo esetshenziswa ekukhiqizeni imikhiqizo ehlukahlukene, okuhlanganisa amabhande okunwebeka, izicathulo, amakepisi okubhukuda, namapayipi.Eqinisweni, ukukhiqizwa kwamasondo ezimoto kudla cishe ingxenye yayo yonke irabha ekhiqizwayo.Uma kubhekwa ukubaluleka kwayo, kufanelekile ukuhlola inqubo yokudala irabha kanye nomsuka wayo.Lesi sihloko sizonaka ukwethula ngemvelaphi yenjoloba,indlela yokwenza irabha,izicelo zenjoloba, uhlobo lwerabhafuthikungani ukhetha irabhanjengezinto zokusetshenziswa zomkhiqizo.
Umsuka wenjoloba
Sekuyiminyaka engaphezu kwenkulungwane, abantu besebenzisa izimfanelo zenjoloba ezinamandla nezivumelana nezimo ukuze benze izinto ezihlukahlukene.Ekuqaleni ithathwe ezintweni zemvelo, kodwa ngenxa yenjoloba idume kakhulu futhi ukwanda kwesidingo kuholele ekutheni abantu bathande ukwenza irabha kumalebhu engakhiqiza iraba enohlamvu oluningi.Namuhla, iningi lenjoloba esiyisebenzisayo ikhiqizwa ngokwenziwa.
Yenziwa Kanjani Irabha Yemvelo
Izinhlobo ezahlukahlukene zenjoloba yokwenziwa zisebenza imisebenzi ehlukene ngakho-ke, izindlela zokukhiqiza zingahluka kakhulu.Esikhundleni sokuthembela emithonjeni yemvelo, lawa ma-rubber enziwa ngezinqubo zamakhemikhali ezifana ne-polymerization.Izinto ezisetshenziswayo ezijwayelekile ezifana namalahle, uwoyela, nama-hydrocarbon ziyacwengwa ukuze kudaleke i-naphtha.I-Naphtha ibe isixutshwa negesi yemvelo ukwenza i-mon ephinde icutshungulwe ibe ngamaketanga e-polymer kusetshenziswa isitimu kanye ne-vulcanization ukuze kukhiqizwe irabha.
Inqubo yerabha
1.Ukuhlanganisa
Ukufaka izithasiselo zamakhemikhali kusisekelo senjoloba kungakhiqiza izinhlanganisela zenjoloba ezinezakhiwo ezithuthukisiwe.Lawa makhemikhali angakwazi ukuzinzisa isakhiwo se-polymer noma athuthukise amandla erabha.Ukwengeza, inqubo yokuhlanganisa ngezinye izikhathi ingakhuphula ukunwebeka kwenjoloba, okuholela ezindlekweni zokugcina eziphansi.
2.Ukuxuba
Ngenqubo efana nokuhlanganisa, izithasiselo zihlanganiswa nerabha kulesi sigaba.Ukuqinisekisa ukusatshalaliswa okufanele kwezithako nokuvimbela ukushisa ngokweqile, abaxube abanekhono benza le nqubo ngezigaba ezimbili.Okokuqala, abantu bazolungisa i-masterbatch equkethe izithasiselo ezifana ne-carbon black.Uma injoloba isipholile, bethula amakhemikhali adingekayo ukuze i-vulcanization.
3.Ukubumba
Abakhiqizi bangase basebenzise izindlela zokubumba ezihlukahlukene ezifana nokumboza, ukukhishwa, ukubunjwa, ukufakwa kwekhalenda, nokubumba ukuze kukhiqizwe inhlobonhlobo yemikhiqizo.Ukukhethwa kwesu lokubumba kuncike ezidingweni ezithile zomkhiqizo wokugcina.
4.I-Vulcanization
Ukuze kuthuthukiswe ukuqina namandla ayo, irabha ithola ukwelashwa okushisayo okwaziwa ngokuthi i-vulcanization.Le nqubo ihilela ukushisa irabha, ngokuvamile ngesulfure, ukuze kwakhiwe izibopho ezengeziwe phakathi kwama-molecule, okuwenza angajwayele ukuhlukana.Ukulandela ukukhishwa kwe-vulcanization, noma yikuphi ukukhubazeka kuyasuswa, futhi irabha iyabunjwa noma ibunjwe ibe umkhiqizo owufunayo.Injoloba isalokhu iyindalo ebalulekile enezinhlelo zokusebenza ezihlukahlukene, futhi i-Ruicheng inikeza izinhlobonhlobo zemikhiqizo yenjoloba yekhwalithi ephezulu, ehlanganisa ukukhwelana, izigxivizo, nezinsimbi.
Isicelo se-Rubber
Umndeni:Irabha ivamise ukusetshenziswa ekukhiqizeni izicathulo, amabhuzu, nezinye izicathulo ngenxa yokuqina kwayo kanye nezindawo ezimelana namanzi.
Ezezimoto:Irabha isetshenziswa ezingxenyeni zezimoto ezahlukahlukene njengamapayipi, amabhande, amabhushi, nezimbobo zenjini ukuze kunciphe ukudlidliza nokumuncwa ukushaqeka.Ikakhulukazi amathayi, irabha iyingxenye ebalulekile yokwenziwa kwamasondo ezimoto, amabhayisikili, nezinye izimoto.
Amadivayisi Ezokwelapha: Ngenxa yezici eziningi ezinhle zenjoloba, imikhakha yezokwelapha kuyo yonke imboni isebenzisa izinto ezisetshenziswayo ezihlukahlukene.Ochwepheshe bezokwelapha, okuhlanganisa ochwepheshe bezindlebe, ikhala, nomphimbo, benhliziyo, i-oncology, i-ophthalmology, ukuhlinzwa kwepulasitiki, nokuhlinzwa okuvamile kuphendukela kunjoloba ewuketshezi ye-silicone kanye nokubumba kwenjoloba yezokwelapha ukuze kusetshenziswe kanye nezisetshenziswa zezokwelapha ezisebenziseka kabusha.
Ngaso leso sikhathi, iRubber isetshenziswa ekwenzeni izinto zezokwelapha ezifana namagilavu, amashubhu, nezigxivizo ngenxa ye-biocompatibility yayo kanye nokuvumelana nezimo.
Izimpahla Zezemidlalo: Irabha isetshenziswa ekukhiqizeni okokusebenza kwezemidlalo okufana namabhola, ama-grips, nama-padding ngenxa yokunwebeka kwayo kanye nokumelana nomthelela.
Izinhlobo ezivamile zenjoloba
Irabha yemvelo
Irabha yemvelo itholakala ngokukhipha uketshezi oluwuketshezi, olubizwa nge-latex, ezinhlotsheni ezihlukahlukene zezihlahla, kanti isihlahla se-Hevea brasiliensis siwumthombo oyinhloko.Inqubo yokuqoqa i-latex ihlanganisa ukusika amagxolo nokuqoqa uketshezi ezinkomishini, inqubo eyaziwa ngokuthi ukucofa.Ukuvimbela ukuqina, i-ammonia yengezwa, ilandelwa i-asidi ukuze kukhishwe irabha ngokuhlangana, okuthatha cishe amahora angu-12.Ingxube ibe isidluliswa ngama-rollers ukuze kukhishwe amanzi amaningi, futhi izingqimba zenjoloba zomiswa ngokuzilenga phezu kwama-racks kuma-smokehouses noma zomiswe emoyeni.
Irabha yokwenziwa
Ososayensi baseJalimane bakha irabha yokwenziwa phakathi neMpi Yezwe I ngenxa yokushoda kwemithombo yemvelo yenjoloba.Nakuba ekuqaleni yayisezingeni eliphansi kunerabha yemvelo, irabha yokwenziwa iye yathuthuka ngokuhamba kwesikhathi ngocwaningo nokuthuthukiswa.Namuhla, irabha yokwenziwa iqinile futhi ithembekile njengozakwabo wemvelo.Umehluko omkhulu phakathi kwenjoloba yokwenziwa neyemvelo useqinisweni lokuthi irabha yokwenziwa ikhiqizwa ngokuxhuma ama-molecule e-polymer elebhu.Manje abakhiqizi abaningi bathanda ukusebenzisa irabha yokwenziwa.
Izinzuzo zenjoloba
Ukuguquguquka nokunwebeka: Irabha yaziwa ngokunwebeka kwayo okuphezulu nokuguquguquka, ukuyivumela ukuthi ikhubazeke ngaphansi kwengcindezi futhi ibuyele esimweni sayo sasekuqaleni lapho ukucindezeleka kususwa.Lesi sakhiwo senza irabha ilungele ukusetshenziswa lapho kudingeka khona ukuqina nokuvumelana nezimo, njengakumathayi, ama-seal, nezinqamuleli zokushaqeka.
Ukumelana nokuguga: Irabha ikhombisa ukumelana okuphezulu nokuhuzuka, ukuguga, nokudabuka, iyenze iqine futhi ihlale isikhathi eside.Lesi sakhiwo senza irabha ifanelekele izinhlelo zokusebenza ezibandakanya ukungqubuzana njalo nokuchayeka ezindaweni ezinokhahlo, njengamabhande okuthutha, amapayipi ezimboni, nezinto zezimoto.
Ukuncishiswa komsindo: Irabha ingadambisa ngempumelelo ukundindizela futhi inciphise umsindo, iyenze ifanelekele ukusetshenziswa ezinhlelweni lapho ukunciphisa umsindo kubalulekile, njengasezintweni zezimoto nezinto zokwakha.
Ukumuncwa ukushaqeka: Irabha inezinto ezinhle kakhulu ezimunca ukushaqeka, okuyenza ifaneleke ukusetshenziswa emikhiqizweni efana nezicathulo, okokusebenza kwezemidlalo, nezinsimbi zokuzihlukanisa zokudlidliza.
Lezi zinzuzo zenza irabha ibe yinto ebalulekile ezinhlobonhlobo zezimboni, okuhlanganisa ezezimoto, ezokwakha, ezogesi, ezokunakekelwa kwezempilo, kanye nezimpahla zabathengi.
Isifinyezo
Lesi sihloko sahlola izimfanelo zenjoloba, sacacisa ngemvelaphi yayo, umfakisicelo kanye nezinzuzo, futhi sethula izinhlobo ezihlukahlukene zenjoloba ezivamile engazithatha ezisetshenziswa zezimboni.sethemba ukuthi lesi sihloko sikusize ubone ukuthi kungakanani ukusetshenziswa kwenjoloba okukhona ngempela.Ngenjoloba, amathuba angenamkhawulo.Uma ufuna ukwazi okwengeziwe,sicela usithinte!
