Ukusuka kwi-chute kunye ne-hopper linings ukuya kwi-conveyors okanye izinto, ii-wear pads, ii-machine rails, iindawo ezigugulekayo kunye nee-rails, amaphepha e-UHMWPE lukhetho lokuqala.
Kodwa akuphelelanga apho! Iphepha le-UHMWPE linezinye iingenelo ezininzi ezenza ukuba libe yinto ephambili kwizicelo zobunjineli. Okokuqala, alina-UV, oko kuthetha ukuba linokumelana nokukhanya kwelanga ixesha elide ngaphandle kokuwohloka. Oku kuyenza ifaneleke ukusetyenziswa ngaphandle, kuqinisekisa ukuba ihlala ixesha elide kwaye ithembekile kuzo zonke iimeko zemozulu.
Olunye uphawu oluphawulekayo lweIphepha le-UHMWPEyindlela esebenza ngayo kakuhle. I-coefficient yayo ephantsi yokungqubana kunye nokulula kokuyicubungula kuyenza ibe yinto eguquguqukayo kwiinjongo zobunjineli. Nokuba kukusikwa, ukugrumba okanye ukwenza, amaphepha e-UHMWPE anokucutshungulwa ngokulula ukuhlangabezana neemfuno ezithile, oko konga ixesha kunye nomgudu.
Ukongeza, amaphepha e-UHMWPE phantse akhuselekile ngokupheleleyo kuhlaselo lweekhemikhali. Ayinakumelana kakhulu neekhemikhali ezahlukeneyo, ii-asidi kunye neziseko, nto leyo eqinisekisa ukuba iyasebenza nakwiindawo ezinzima. Oku kuyenza ilungele ukusetyenziswa kwizinto ezinokutsha.
Ukongeza ekuchaseni iikhemikhali,Iphepha le-UHMWPEnazo azivali kwaye azinamatheli. Oku kuthetha ukuba izinto kunye nenkunkuma akunakwenzeka ukuba zinamathele okanye zinamathele kumphezulu wazo, nto leyo ebangela ukusebenza kakuhle kunye nokunciphisa iimfuno zokugcinwa kwazo. Nokuba ziinkozo, amalahle okanye ezinye izinto, amaphepha e-UHMWPE aqinisekisa ukuhamba kakuhle komoya kwaye athintele ukuvaleka.
