1. Irabha ye-Nitrile
Irabha ye-Nitrile isetyenziswa kakhulu ekwenzeni iimveliso zerabha ezixhathisa ioli.I-NBR ngokufutshane, irabha yokwenziwa eyenziwe nge-copolymerizing butadiene kunye ne-acrylonitrile.Yirabha yokwenziwa enokumelana neoli elungileyo (ingakumbi ioli yealkane) kunye nokumelana nokuguga.
I-rubber ye-Nitrile iveliswa yi-emulsion polymerization ye-butadiene kunye ne-acrylonitrile.Irabha yeNitrile iveliswa ikakhulu yipolymerization ye-emulsion yobushushu obuphantsi.Inokumelana ne-oyile okugqwesileyo, ukumelana nokunxiba okuphezulu, ukumelana nobushushu obuhle kunye nokuncamathela okuqinileyo..
Ukungalungi kwayo kukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, ukusebenza kakubi kokugquma, kunye nokuqina okuncinci.Ingasetyenziswa ixesha elide emoyeni kwi-120°C okanye kwi-oyile kwi-150°C.
Ukongeza, ikwanazo ukumelana namanzi kakuhle, ukuxinana komoya kunye nokusebenza okugqwesileyo kokudibanisa, kwaye isetyenziswa kakhulu kwimveliso yeemveliso ezahlukeneyo zerabha ezinganyangekiyo kwioyile.
2. Irabha ye-EPDM
Irabha ye-EPDM yi-non-polar, isakhiwo esigcweleyo.Okubizwa ngokuba yi "non-polar" kuthetha ukuba iimolekyuli ezenza i-polymer aziqukethe amaqela e-polar.Okubizwa ngokuba "i-saturation" kuthetha ukuba iamolekyu ezenza i-polymer aziqukethe iibhondi ezimbini.
I-EPDM (i-ethylene propylene diene monomer), njengohlobo lwerabha ene-elasticity elungileyo, ukumelana nokunxiba, ukumelana nobushushu, ukumelana nemozulu, ukuxhathisa kwe-ozone, ukuxhathisa kwamanzi amatsha kunye nolwandle, isetyenziswe ngokubanzi kwiimveliso zerabha kwiimoto.
3. Indlela yokugweba ukuba i-hose yerabha ilungile okanye imbi?
Jonga umphezulu wethumbu lerabha: Kukho iindidi ezimbini zomphezulu werabha, umphezulu ogudileyo kunye nomphezulu welaphu.Ubuso obugudileyo bufuna indawo egudileyo ngaphandle kwamaqamu kunye neeprotrusions;umgangatho owenziweyo ufuna ukuba ilaphu elijikelezileyo libe mcaba kwaye kumgama ofanayo.
Jonga i-reinforcement layer: i-reinforcement layer ijikelezwe ngokubanzi ngamafayili kunye neengcingo zetsimbi.Okukhona iileya ezininzi, kokukhona uxinzelelo olukhulu olufunyenweyo, oluyinjongo ebalulekileyo yocalucalulo.
Khangela ukuba i-hose ye-rubber i-eccentric: phantsi kweemeko eziqhelekileyo, i-core tube yerubha ikwimo yesangqa esipheleleyo.Ukuba i-elliptical okanye ayiphelelanga isangqa, inokuchaphazela ukusetyenziswa ityhubhu yerubha.
Jonga indlela egoba ngayo ithumbu lerabha: gobela umbhobho phakathi, jonga umbala womphezulu kunye nesantya sokubuyela umva, utshintsho lombala luncinci, kwaye isantya sokubuyela umva siyakhawuleza, nto leyo engqina ukuba umgangatho wombhobho ulungile.
