Polyethylene ea High Density ke eng

High density polyethylene (HDPE), phofo e tšoeu kapa sehlahisoa sa granular. E se nang chefo, e sa latsoeheng, e kristale ea 80% ho isa ho 90%, ntlha e nolofatsang ea 125 ho ea ho 135 ° C, e sebelisa mocheso ho fihlela ho 100 ° C; ho thatafala, matla a thata le ductility li molemo ho feta polyethylene e tlaase; wear resistance, motlakase Insulation e ntle, ho tiea le ho hanyetsa serame; botsitso bo botle ba lik'hemik'hale, bo ke keng ba qhibiliha ka har'a mokelikeli leha e le ofe oa manyolo ka mocheso oa kamore, ho hanyetsa kutu ea acid, alkali le matsoai a sa tšoaneng; tšesaane filimi permeability ho mouoane oa metsi le moea, ho monya metsi Ho tlaase; ho hanyetsa botsofali ho futsanehile, khatello ea khatello ea kelello ea tikoloho ha e tšoane le polyethylene e tlaase, haholo-holo oxidation ea mocheso e tla fokotsa ts'ebetso ea eona, kahoo li-antioxidants le li-ultraviolet absorbers li tlameha ho kenngoa ho resin ho ntlafatsa khaello ena.

[Litšobotsi tsa mantlha] HDPE ke ntho e kang boka bo bosoeu bo opaque e nang le matla a khoheli a itseng a bobebe ho feta metsi, ka matla a khoheli a itseng a 0.941 ~ 0.960. E bonolo ebile e thata, empa e thata hanyane ho feta LDPE, hape e ka otloha hanyane, ha e na chefo ebile ha e latsoehe.

[Litšobotsi tsa ho tuka] E ea cha 'me e ka tsoela pele ho tuka ka mor'a hore e tlohe mollong. Karolo e ka holimo ea lelakabe e mosehla 'me karolo e ka tlaase e putsoa. Ha e chesa, e tla qhibiliha, ho tla ba le metsi a rothang, 'me ha ho mosi o motšo o tla hlaha. Ka nako e tšoanang, e ntša monko oa ho chesa parafine.

[Melemo e ka sehloohong] Acid le alkali resistance, organic solvent resistance, motlakase o motle haholo, 'me o ntse o ka boloka boima bo itseng mochesong o tlase. Ho thatafala ka holim'a metsi, matla a thata, ho tiea le matla a mang a mochine a phahame ho feta LDPE, haufi le PP, a matla ho feta PP, empa qetello ea bokaholimo ha e tšoane le PP.

[Mathata a mantlha] Thepa e sa sebetseng hantle, moea o fokang, moea o fokolang, ho fetoha ha bonolo, ho tsofala habonolo, ho ba brittle, ho fokola ho feta PP, ho peperana habonolo, ho thatafala ha bokaholimo bo tlase, ho hoa habonolo. Ho thata ho hatisa, ha ho hatisoa, phekolo ea ho tsoa holimo e hlokahalang, ha ho na electroplating, 'me bokaholimo bo lerootho.
