Isicelo

1. Ukhuseleko oluphambili lweemveliso zerabha: ukulwa nokwaluphala kunye nobomi benkonzo ende

Le yeyona ndlela isetyenziswa ngayo, ibonelela ngokhuseleko olubalulekileyo kwiingxaki zokwaluphala zerabha ezibangelwa "bubushushu, i-ozone, kunye ne-oxidation" ngexesha lokusetyenziswa (njengokuqina, ukuqhekeka, kunye nokuncipha kokuguquguquka).

Ukwenziwa kwamatayara: Isetyenziswa kwiikhompawundi zerabha ezisetyenziswa kwi-tread nakwicala leentambo zeentayi ezahlukeneyo ezifana neemoto, iilori, kunye noomatshini bokwakha ukumelana nobushushu obubangelwa kukungqubana ngexesha lokusebenza kwezithuthi kunye nokukhukuliseka kwe-ozone emoyeni, ukulibazisa ukuguga nokuqhekeka kwamatayara, kunye nokwandisa ubomi bawo benkonzo.

Iimveliso zerabha zorhwebo: Zifanelekile kwiipayipi zerabha (ezifana nemibhobho yeoyile negesi), iibhanti zokuhambisa (zemigodi nezothutho), kunye nezitywino (ii-O-rings, ii-gaskets), ukuthintela ezi mveliso ukuba zingagugi kwaye zingaphumeleli xa zibekwe kwindawo engaphandle okanye enzima (ezifana namaqondo obushushu aphezulu kunye nokufuma) ixesha elide.

Iimveliso zerabha ezisetyenziswa imihla ngemihla/ezikhethekileyo: ezisetyenziselwa imicu yerabha ye-wiper, ii-gasket zerabha, irabha efunxa ukutshaqeka (kwiimoto/oomatshini), kunye neemveliso ezenziwe ngerabha yokwenziwa efana nerabha ye-chloroprene kunye nerabha ye-styrene-butadiene, ezigcina ukuthamba kwazo ixesha elide kunye nokusebenza kwazo xa zisetyenziswa.

2. Izongezo zokukhusela irabha kwiimeko ezithile

Ukongeza kukhuseleko oluqhelekileyo, iingxaki ezithile zokwaluphala zinokujongwa ngokukodwa ngokusekwe kwindawo yokusetyenziswa kweemveliso zerabha:

Ukwaluphala kokudinwa okuchasene nokuguquguquka: Isetyenziselwa izinto zerabha ezifuna ukuxhatshazwa ngamandla aphindaphindwayo (ezifana neebhanti zokuhambisa kunye nee-shock absorbers), ukunciphisa "ukuqhekeka kokudinwa" okubangelwa yimpembelelo edibeneyo yoxinzelelo oluguquguqukayo kunye ne-oxidation.

Uncedo lokukhusela ubushushu obuphezulu: Kwiimveliso zerabha ezisetyenziswa kwiindawo ezinobushushu obuphakathi nobuphezulu (ezifana nezitywini ze-injini), xa zidibene nezinye ii-antioxidants, ziyawonyusa ukumelana ne-oxidation yobushushu zerabha kwaye ziyithintele ekubeni iqine ngokukhawuleza kwaye ibe buthathaka xa ishushu kakhulu.

Uphawu

1. Ubumsulwa ≥ 99.99%, budlula umgangatho weshishini webhetri;
2. Umxholo wobumanzi ≤50 ppm, ukusebenza kakuhle kobushushu;
3. Uzinzo oluhle kakhulu lobushushu
4. Ikhona kwisitokhwe
