Isipiliyoni seminyaka engaphezu kwengu-20 emkhakheni we-hose.
I-PEX-B yenziwa kusetshenziswa indlela ye-“Silane” noma “Yokwelapha Umswakama” yokuxhumanisa, lapho izixhumanisi phakathi kwama-molecule e-Polyethylene polymer kwakheka ngemva kwenqubo yokukhipha kusetshenziswa i-catalyst nangokudalula ishubhu le-PEX emanzini (ukugeza umusi) eyenza i-HDPE (i-polyethylene ephezulu-density).
I-PEX-B iwinile ngokusobala ngokuya ngekhwalithi iqhudelana ne-PEX-A. Isetshenziswe iminyaka engaphezu kwengu-33 ngaphandle kwezinkinga ezaziwayo, njengoba iwaranti evamile yanoma yiluphi olunye uhlobo lwe-PEX yiminyaka eyi-10-15 kuphela. Abakhiqizi be-PEX-B banikeza iwaranti yeminyaka engama-25. I-PEX-B futhi ukuphela kwe-PEX ekwazi ukumelana namanzi ashisayo aqhubekayo (+140 degrees) asuka kumaphampu aphinda ajikelezwe. Yonke enye i-PEX idinga isibali sikhathi noma ukuchayeka okulinganiselwe emanzini ashisayo (+140 degrees). Iphinde ibe nokucindezela okuphezulu kokuqhuma kune-PEX-A kanye nokumelana okungcono ne-oxidation - into ebaluleke kakhulu ekufakweni kwamapayipi.
I-chlorine ephezulu kanye nokumelana ne-oxidative
Ingcindezi yokuqhuma ephezulu kakhulu.
Awekho amakhemikhali aphumayo ohlelweni lokukhiqiza.
Ukucindezela okuphezulu kokuqhuma.
Ukuhlukahluka kokubekezelelana okuphansi kakhulu.
Isilinganiso esiphansi sokuxhumanisa kune-PEX-A.
I-Hangzhou Paishun Rubber And Plastic Company, umkhiqizi owasungulwa ngo-2007, ingeyakhe indlunkulu yethu edolobheni elihle lomlando lase-Hangzhou.
