Imikhiqizo Ebunjiwe Yokujova Ngokwezifiso

Izinqubo Zokukhiqiza Imikhiqizo Yerabha

Ukukhiqizwa kwezimpahla zenjoloba kuhilela izinqubo ezimbalwa eziyinkimbinkimbi eziguqula izinto zenjoloba ezingavuthiwe zibe imikhiqizo yokugcina. Lezi zinqubo ziyahlukahluka kuye ngohlobo lwerabha esetshenzisiwe kanye nento ethile ekhiqizwayo. Okulandelayo yizinsizakalo zokukhiqiza irabha esizihlinzekayo ukuze sisekele izidingo zakho:

Ukubunjwa Kokucindezela

Ekubunjweni kokucindezelwa, inhlanganisela yerabha ifakwa endaweni yokubumba, futhi ingcindezi isetshenziswa ukucindezela impahla ibe yisimo esifunwayo. Ukushisa bese kusetshenziswa ukwelapha irabha. Le ndlela ivame ukusetshenziselwa ukukhiqiza imikhiqizo efana ne-gaskets, izimpawu, kanye nezingxenye zezimoto.

Ukubunjwa komjovo

Ukubumba umjovo kuhlanganisa ukujova irabha encibilikisiwe esikhunjeni ngaphansi kwengcindezi ephezulu. Le nqubo ilungele ukwenza izingxenye eziyinkimbinkimbi nezinembayo, ezifaka izingxenye zezimoto nezimpahla zabathengi. Ukubunjwa kwe-overmolding kanye nokufaka izinhlobonhlobo zale nqubo, ezibandakanya ukuhlanganiswa kwezingxenye zensimbi eziqediwe endaweni yokubumba ngaphambi kokujova irabha.

Dlulisa Ukubumba

Ukuhlanganisa izici zokucindezelwa nokubunjwa komjovo, ukubumba kokudlulisa kusebenzisa inani elilinganiselwe lenjoloba ekamelweni elishisayo. I-plunger iphoqelela okokusebenza endaweni yokubumba, iyenze ifaneleke ukukhiqiza izixhumi zikagesi, ama-grommets, nezingxenye ezincane ezinembayo.

I-Extrusion

I-Extrusion isetshenziselwa ukudala ubude obuqhubekayo berabha enomumo othize we-cross-sectional, njengamapayipi, amashubhu, namaphrofayela. Irabha iphoqelelwa nge-die ukuze kuzuzwe ukucushwa okufunayo.

Ukwelapha (Vulcanization)

Ukwelapha, noma ukwenza i-vulcanization, kuhlanganisa ukuxhumanisa amaketanga e-polymer yenjoloba ukuze kuthuthukiswe amandla, ukunwebeka, nokumelana nokushisa. Lokhu kufezwa ngokusebenzisa ukushisa nokucindezela emkhiqizweni wenjoloba ebunjiwe, ngezindlela ezivamile ezihlanganisa isitimu, umoya oshisayo, nokwelapha nge-microwave.

Irabha ukuze Metal Bonding

Inqubo ekhethekile, i-rubber to metal bonding idala imikhiqizo ehlanganisa ukuguquguquka kwerabha namandla ensimbi. Ingxenye yenjoloba yenziwe kusengaphambili noma ibunjwe, ibekwe endaweni yensimbi nge-adhesive, bese ingaphansi kokushisa nokucindezela kokuvuthwa noma ukuphulukiswa. Le nqubo ibopha ngokwekhemikhali irabha ensimbi, idale uxhumano oluqinile noluhlala isikhathi eside olubalulekile ezinhlelweni ezidinga kokubili ukudambisa ukudlidliza nokusekelwa kwesakhiwo.

Ukuhlanganisa

Ukuhlanganisa kuhlanganisa ukuxuba izinto zenjoloba eluhlaza nezithasiselo ezihlukahlukene ukuze kwakhiwe inhlanganisela yerabha enezici ezithile. Izengezo zingabandakanya ama-ejenti okwelapha, ama-accelerator, ama-antioxidants, ama-filler, ama-plasticizers, nama-colorants. Lokhu kuxutshwa kuvame ukwenziwa emshinini onama-roll amabili noma kumxube wangaphakathi ukuze kuqinisekiswe ukusatshalaliswa okufanayo kwezithasiselo.

Ukugaya

Ukulandela ukuhlanganiswa, i-compound yerabha ibhekana nezinqubo zokugaya noma zokuxuba ukuze kuthuthukiswe i-homogenize futhi ilolonge into. Lesi sinyathelo sisusa amabhamuza omoya futhi siqinisekisa ukufana kunhlanganisela.

Ngemuva kokucubungula

Ngemva kokwelashwa, umkhiqizo wenjoloba ungase ubhekane nezinqubo ezengeziwe, okuhlanganisa ukugunda, ukucwazimula (ukukhipha izinto ezidingekayo), nokwelashwa kwangaphandle (okufana nokunamathiswa noma ukupholishwa) ukuze uhlangabezane nezimfuneko ezithile.

Ukusetshenziswa kwengxenye yeRubber Molding

Ukubumba kwerabha kuhlukanisa ngezinhlobo ezintathu ngokusekelwe ezintweni ezibonakalayo zenjoloba ezihlukile: ukubumba komjovo werabha ye-butyl, ukubumba komjovo wenjoloba we-nitrile, kanye nokubumba komjovo werabha owuketshezi we-LSR. Ngezansi kunezibonelo zezingxenye ezibunjiwe zenjoloba ngokwezifiso eziqondene nohlobo ngalunye lomjovo wenjoloba:

1.I-Butyl Rubber Molding Molding

2.Nitrile Rubber Umjovo Molding

3.LSR Liquid Silicone Rubber Umjovo

I-MoldingLezi izibonelo ezimbalwa zezingxenye ezibunjwe ngenjoloba yangokwezifiso ezingakhiqizwa kusetshenziswa irabha ye-butyl, irabha ye-nitrile, kanye namasu okubumba umjovo we-LSR. Uhlobo ngalunye lwento yenjoloba lunikeza izakhiwo ezithile kanye nezinzuzo, okulwenza lufanelekele ukusetshenziswa okuhlukahlukene kuzo zonke izimboni ezahlukene.

I-Rubber Molding Materials

Uhlobo ngalunye lwerabha lunesethi ehlukile yezakhiwo, luyenza ifanelekele izinhlelo ezithile. Ukukhethwa kwezinto zenjoloba kuncike ezintweni ezifana nokusetshenziswa okuhlosiwe, izimo zemvelo, izinga lokushisa, ukuchayeka kwamakhemikhali, nezici zomzimba ezifiswayo.

Nazi ezinye izinhlobo eziyinhloko zerabha:

Irabha Yemvelo (NR):

Isuselwa kuncindi ye-latex yesihlahla senjoloba (i-Hevea brasiliensis), irabha yemvelo yaziwa ngokunwebeka kwayo okuphezulu nokuqina. Isetshenziswa kakhulu ezinhlelweni ezifana namathayi, izicathulo, nemikhiqizo yabathengi, inokumelana okulinganiselwe ekushiseni nakumakhemikhali.

Irabha Yokwenziwa:

Idalwe ngokwenziwa ngezinqubo zamakhemikhali, amarabha okwenziwa anikeza izinhlobonhlobo zezakhiwo. Ezinye izinhlobo ezijwayelekile zihlanganisa:

Irabha ye-Styrene-Butadiene (SBR)

Isetshenziselwa kakhulu ukumelana nokuhuzuka nokuqina, okuvame ukutholakala emathayini emoto namabhande okuthutha.

Irabha ye-Polybutadiene (BR):

Ibaluleke kakhulu ngenxa yokuqina okuphezulu nokuguquguquka kwezinga lokushisa eliphansi, okuvamise ukusetshenziswa ekwenziweni kwamathayi nanjengesilungisi somthelela kumapulasitiki.

I-Nitrile Rubber (NBR):

Ibonisa ukumelana nowoyela, uphethiloli, namakhemikhali okukhethekile, okuyenza ifanelekele izinti, ama-gaskets, nama-O-rings emkhakheni wezimoto nezimboni.

I-Butyl Rubber (IIR):

Kwaziwa ngokungakwazi ukungena kwamagesi, ilungele amashubhu angaphakathi amathayi, olayini bangaphakathi bamathange okugcina amakhemikhali, nezivalo zemithi.

I-Neoprene (CR):

Inikeza ukumelana okuhle kakhulu nesimo sezulu, i-ozone, namafutha, ukukhetha okudumile kwama-wetsuits, amapayipi, nama-gaskets ezimoto.

I-Ethylene Propylene Diene Monomer (EPDM):

Ingamelana nokushisa, isimo sezulu, kanye nemisebe ye-UV, evame ukusetshenziswa ezintweni zokufulela, izigxivizo zezimoto, kanye nokufakwa kukagesi kwangaphandle.

Irabha yeSilicone (VMQ):

Yaziwa kakhulu ngokumelana nokushisa okuhle kakhulu kanye nezakhiwo zokuvala ugesi, ezivame ukusetshenziswa emishinini yezokwelapha, i-cookware, izinhlelo zokusebenza zezimoto, nanjenge-sealant.

I-Fluoroelastomers (FKM):

Imelana kakhulu namakhemikhali, amazinga okushisa aphezulu, namafutha, asetshenziswa kakhulu ezinhlelweni ezidinga ukumelana namakhemikhali okuhlukile, njengezimvu zamanzi kanye nama-gaskets ezimbonini zamakhemikhali nezomkhathi.

Irabha yeChloroprene (CR):

Eyaziwa nangokuthi i-Neoprene, inikeza ukumelana okuhle nesimo sezulu kanye ne-ozone. Ivamise ukusetshenziswa ezinhlelweni ezidinga ibhalansi yezinto ezibonakalayo, njengama-wetsuits namabhande ezimbonini.

I-Polyurethane (PU):

Ukuhlanganisa izakhiwo zenjoloba nepulasitiki, irabha ye-polyurethane iyaziswa ngenxa yokumelana nokuhuzuka kanye namandla okuthwala umthwalo. Isetshenziswa kakhulu kumasondo, ama-bushings, nezingxenye zemishini yezimboni.
