High density Polyethylene yeeb nkab Qib
HDPE yeeb nkab qib muaj dav lossis bimodal faib ntawm molecular hnyav.Nws muaj zog creep kuj thiab zoo sib npaug ntawm rigidity thiab toughness.Nws yog ruaj heev thiab muaj tsawg sag thaum ua tiav.Cov kav dej uas tsim los ntawm cov khoom siv no muaj lub zog zoo, rigidity thiab kev cuam tshuam tsis zoo thiab cov cuab yeej zoo ntawm SCG thiab RCP.
Cov resin yuav tsum tau muab khaws cia rau hauv ib qho chaw qhuav, qhuav warehouse thiab deb ntawm hluav taws thiab tshav ntuj ncaj qha.Nws yuav tsum tsis txhob muab tso rau hauv qhov qhib cua.Thaum lub sij hawm kev thauj mus los, cov khoom yuav tsum tsis txhob raug tshav ntuj los yog nag thiab yuav tsum tsis txhob raug thauj nrog xuab zeb, av, seem hlau, thee lossis iav.Kev thauj mus los ua ke nrog cov tshuaj lom, corrosive thiab flammable yog nruj me ntsis txwv.
Daim ntawv thov
HDPE yeeb nkab qib tuaj yeem siv rau hauv kev tsim cov kav dej siab, xws li cov kav dej siab, cov kav dej roj thiab lwm cov kav dej.Nws kuj tseem siv tau los ua cov kav dej tsis muaj zog xws li ob-phab ntsa corrugated kav, hollow-wall winding kav, silicon-core kav, kav dej ua liaj ua teb thiab aluminiumplastics compound pipes.Tsis tas li ntawd, los ntawm reactive extrusion (silane cross-linking), nws tuaj yeem siv los ua cov kav dej sib txuas polyethylene (PEX) rau kev muab dej txias thiab dej kub.
