I-HDPE Ubushushu boMbhobho we-Extrusion Line
Umbhobho wokugquma we-PE ukwabizwa ngokuba yi-PE umbhobho wokukhusela wangaphandle, umbhobho webhatyi, umbhobho wemikhono. Umbhobho wokugquma we-polyurethane ongcwatywe ngokuthe ngqo wenziwa ngombhobho wokugquma we-HDPE njengomaleko okhuselayo wangaphandle, i-foam ephakathi ezaliswe yi-polyurethane eqinile isetyenziswa njengomaleko wezinto zokugquma, kwaye umaleko wangaphakathi ngumbhobho wentsimbi. I-polyure-thane ngqo engcwatywa umbhobho wokugquma uneempawu ezilungileyo zoomatshini kunye nokusebenza kokufakelwa kwe-thermal. Phantsi kweemeko eziqhelekileyo, inokumelana nobushushu obuphezulu be-120-180 °C, kwaye ilungele iiprojekthi ezahlukeneyo zokugquma imibhobho yamanzi abandayo nashushu.
