Kutheni ukhetha irabha yokwenziwa?

Kwiminyaka yakutshanje, amashishini amaninzi, kubandakanywa nathi, senze i-rubber yendalo ukuyaeyenziweyo.Kodwa yintoni kanye kanye umahluko phakathi kwezi zimbini?Ziziphi iintlobo ezahlukeneyo ze-synthetics kwaye ziyakwazi ukubamba imibhobho yerabha yendalo?Inqaku elilandelayo liye lahlanganiswa ukuze kuphendulwe le mibuzo neminye.

Irabha yeNdalo vs irabha yokwenziwa: nguwuphi umahluko?
Irabha yendalo isuka kwiHevea brasiliensis (okanye kumthi werabha wePará) luhlobo lwesityalo esiyinzalelwane yaseBrazil.Irabha yendalo sisixhobo se-elastomer esithandwa kakhulu, esisetyenziswa kwiintlobo ngeentlobo zezicelo nakumashishini.
Irabha yokwenziwa iveliswa ngokungeyomfuneko kwaye yenziwa kwiindidi zeepolymers.Ngenxa yokwenziwa kwayo, iyakwazi ukuguqulwa kwaye ibe nenani leempawu ezahlukeneyo ezongeziweyo kuyo.
Ngokuqhelekileyo, i-rubber yendalo ithathwa njengenamandla kwaye iguquguqukayo, kodwairabha yokwenziwainenzuzo yokuba nemichiza kunye nobushushu obunganyangekiyo.Irabha yokwenziwa kwakhona inenzuzo yokuba neendleko eziphezulu.

Zeziphi iiPropathi zeMibhobho yeRubha yokwenziwa?
Iimpawu eziqhelekileyo zeityhubhu yerabha yokwenziwaziquka:
Ukuguquguquka - Iibhobho zeRubber zilungele nasiphi na isicelo esifuna i-hose eguquguqukayo okanye ityhubhu.Irabha iyaziwa ngokukwazi ukugcina ukuguquguquka kwayo, ngelixa ikwazi ukumelana ne-kinks kunye ne-abrasions.
Ukumelana nobushushu - Imibhobho yerabha yendalo (enyanisweni izinto ezininzi eziqhelekileyo ze-hose) azikwazi ukuphatha amaqondo obushushu agqithisileyo kunye nerubha yokwenziwa.
Ukumelana nemichiza - Umbhobho we-rubber we-rubber yokwenziwa kubhetele ukumelana neekhemikhali xa kuthelekiswa ne-rubber yendalo, kunye nezinye izinto eziqhelekileyo ezisetyenziselwa ukuveliswa kwe-hose, ezinokuthi zibe buthathaka ngokuhamba kwexesha.

Zeziphi Iindidi ezahlukeneyo zeRubha yokwenziwa?
Njengoko irabha yokwenziwa inokuqulatha iipropati ezahlukeneyo, kukho inani leentlobo ezahlukeneyo.
I-EPDM - I-Ethylene Propylene Diene Monomer (EPDM) ixhatshazwa kakhulu kwiikhemikhali ezininzi, ngaphandle kwamafutha kunye namafutha amaminerali.I-UV kunye nokumelana nemozulu, i-EPDM hoses yerabha nayo inokumelana nobushushu obuphezulu.
I-NBR - I-rubber ye-Nitrile butadiene (NBR), nangona ingamelana nemozulu njenge-EPDM, inokuchasana okuphezulu kwi-oyile yamaminerali, okwenza ukuba ifanelekele izicelo i-hose idibene neoli kunye namafutha.
I-SBR - I-rubber ye-Styrene butadiene (SBR) ininzi-injongo-injongo kwaye ayibizi xa kuthelekiswa ne-EPDM kunye ne-NBR.Ngelixa kungabikho ukumelana nemozulu, iyafana ne-EPDM ekuxhathiseni kwayo kweekhemikhali.
I-TPE - Apha eLanboom, uphando lwethu kunye nobuchwepheshe busebenzise izibonelelo zerabha kunye ne-PVC ukuvelisa i-thermoplastic polyester elastomer (TPE).Olu hlobo lwerubha ludityaniswe nePVC ukunika ukuguquguquka okuphuculweyo kumaqondo obushushu aphantsi, njengoko iPVC eqhelekileyo ingaphulukana nokuguquguquka kwayo kunye nokuqhekeka kwezi meko.I-TPE nayo i-taint-free kunye ne-WRAS-ivunyiwe, iyenza ifaneleke kwizicelo zamanzi okusela.
I-TPV – Sihamba phambili ekuphuhliseni i-thermoplastic vulcanizates (TPV).I-TPVs zi-elastomers eziphezulu zokusebenza ezinexabiso elifanayo lexabiso kwirabha.Babonisa uninzi lweempawu kunye nokusebenza kwerabha, kodwa bomelele, bakhaphukhaphu ngakumbi, kwaye banokuphinda kusetyenziswe i-100%.

Zeziphi ii-Aplikheshini Ezona Hoses yerabha yoLwangciso iLufaneleyo?
Ngenxa yeepropati zabo, i-hoses yerabha eyenziwe ngezinto ezininzi kwaye ingasetyenziswa kwinani lezicelo.Ezi zimbalwa nje:
I-Industrial - I-hoses yerabha eyenziwe ngokuqhelekileyo isetyenziswa kwiindawo zoshishino.Ukuxhathisa kwabo kweekhemikhali kubenza balungele ukusetyenziswa okubandakanya ukuhanjiswa komoya, amafutha, okanye ukuthambisa.
Ukwakhiwa - Ukuguquguquka kwabo kunye nokuxhatshazwa kwe-abrasion kubenza balungele izicelo ezibandakanya ukwakhiwa.I-EPDM kunye ne-NBR zinokumelana nemozulu ephezulu, okwenza ukuba zilungele ukusetyenziswa ngaphandle, kunye nangaphakathi.
Amanzi - i-TPE, ngenxa yokuba i-taint-free kunye ne-WRAS-evunyiweyo, ingasetyenziselwa izicelo ezibandakanya ukuhanjiswa kunye nokuhanjiswa kwamanzi okusela.

Kukho inani leentlobo ezahlukeneyo zerabha yokwenziwa, nganye ineempawu zayo, izenza zifaneleke kwizicelo ezahlukeneyo.Sinikezela ngeendidi ezahlukeneyo zemibhobho yerabha, okwenza kube lula kunangaphambili ukufumana imveliso efanelekileyo kuwe.Nceda uzive ukhululekile ukukhangela kuluhlu lwethu lweemveliso, okanye ukuba sele uyifumene into oyifunayo, unokuqhagamshelana nelungu leqela lethu lokuthengisa elinobungane ngekowuti yasimahla.
