Iimveliso

1. Ukumelana nokushisa okuphezulu kunye nokuphantsi: utshintsho lokuphumla kwe-creep yeemveliso phantsi kweemeko eziphezulu okanye eziphantsi zokushisa enye yeemeko zokwahlula umgangatho.Iimveliso zerabha zizinto eziqinileyo ze-elastomer, ezingayi kutshintsha ngokomzimba kwiqondo lokushisa eliqhelekileyo legumbi.Nangona kunjalo, xa ubushushu budlula i-100 ℃, ngaphandle kwezinye iimveliso zerabha zentsimbi, iimveliso ziya kunyonyoba, ezichaphazela ukusetyenziswa.Ngoko ke, kwindawo yokusebenza yokushisa okuphezulu okanye okuphantsi, ukhetho oluchanekileyo lweemveliso zerabha lunokugcina ubomi benkonzo efanelekileyo kunye nokusebenza ngokufanelekileyo.

2. Iimfuno zokhuseleko: ngokweemfuno zokutya, xa ukhetha iimveliso zerabha, nikela ingqalelo ukuba ngaba iimveliso kufuneka zidibanise nokutya okanye zingene ngokuthe ngqo, ezifana ne-pacifiers, iibhotile, njl. Ngokweemfuno zonyango, kuba kuyimfuneko itywina iikhemikhali ezinetyhefu kakhulu, ifuna ukhuseleko olungakumbi.Kwirhasi eguquguqukayo enyibilikisiweyo, ifuna ukuxhathisa kweasidi ephezulu kunye ne-alkali kunye nokubuyiswa komlilo.Njengeemveliso zerabha zonyango, izikhongozeli zeziyobisi, njl.

Kwintsimi yeshishini lepetrochemical, kuyafuneka ukuba kubekho iimfuno zokuthintela umlilo kunye nokumelana nobushushu obuphezulu beemveliso zerabha.Ukuhambisa izixhobo, akufuneki kuphela ukumelana nobushushu obuphezulu, kodwa kunye noxinzelelo olukhulu lokusebenza luyafuneka.

I-3.Iinzuzo zoqoqosho: Namhlanje, iimveliso ezininzi zeerubha zenziwe ngeentlobo zeerubha, eziphantsi kweendleko kwaye zihlangabezana neemfuno.Nangona kunjalo, xa ukhetha iimveliso zerabha, kuyafuneka ukuba kuqwalaselwe ukuba kuya kubangela ukulahleka kwezinto, iziphumo zoqoqosho emva komonakalo kunye nezinye ilahleko.Ke ngoko, xa ukhetha iimveliso zerabha, ukongeza ekukhetheni iimveliso ngokwemfuno, kuyafuneka ukuba kuqwalaselwe ukusebenza kweendleko zazo.
