HDPE QHM32F HDPE-RF ee tuubada kululaynta dabaqa
QHM32F waa resin polyetylen ah oo leh hexene-1 oo ah isku-dheelitir ah oo ay soo saartay nidaamka Unipol ee UCC, USA.Waxay leedahay faa'iidooyinka dabacsanaan wanaagsan, wax qabad heer sare ah, xasilloonida kuleylka iyo iska caabinta cadaadiska.Inta badan loo isticmaalo soo saarista tuubada kululaynta sagxadda, aluminium - tuubo isku dhafan oo balaastik ah, tuubo qorraxda.
Tuubbada PE-RT waa nooc cusub oo ah walxo polyetylen ah oo aan isdhaafsaneyn oo loo isticmaali karo tuubada biyaha kulul.Waa copolymer ethylene iyo octene oo ay soo saartay qaabaynta molecular gaar ah iyo habka isku xidhka, oo leh tiro la xakamayn karo oo silsilad laamo ah iyo qaabdhismeedka qaybinta noocyada polyetylen.Qaab dhismeedka molecular ee gaarka ah wuxuu ka dhigayaa maaddadu inay leedahay iska caabin dildilaaca walaaca oo aad u wanaagsan iyo xoogga hydrostatic ee muddada dheer.Tuubbada PE-RT waxay leedahay dabacsanaan wanaagsan, moodeelkeedu foorarkiisuna waa 550 MPa, culayska gudaha ka dhasha foorarsigu wuu hooseeyaa.Sidan oo kale, waxaa laga fogaanayaa in tuubuhu ay waxyeello u geystaan meesha foorarsiga ah sababtoo ah xoogga saarista cadaadiska.Marka la dhiso (gaar ahaan jiilaalka), uma baahna qalab gaar ah ama kulayl si loo leexiyo.Heerarka kulaylka ee 0.4 W/ (m·k), oo u dhiganta tuubada PE-X, oo aad uga sareysa PP-R 0. 22 W/ (m·k) iyo PB 0. 17 W/ (m·k), conductivity kaamerada aad u fiican, ku haboon tuubada kululaynta dabaqa
Codsiga
QHM32F waa resin gaar ah oo loogu talagalay tuubada PE-RT oo ay soo saartay Laanta Qilu ee Sinopec iyadoo la isticmaalayo tignoolajiyada Unipol.Badeecadu waxay leedahay dabacsanaan wanaagsan, wax qabad heer sare ah, xasilloonida kulaylka iyo iska caabinta cadaadiska, kaas oo buuxin kara shuruudaha processing ee tuubada xawaaraha sare ee qalabka wax soo saarka ee kala duwan iyo caliber, waxaana loo isticmaali karaa wax soo saarka tuubada kuleylka dabaqa, aluminium caag ah oo isku dhafan. dhuumaha, dhuumaha saliidda, iwm.
