Mohala oa ho Ntša Phaephe ea ho Thibela Mocheso oa HDPE

Mohala oa tlhahiso ea phaephe ea ho kenya mocheso o entsoe ka hlobo e khethehileng ea phaephe ea ho kenya mocheso ea PE, khatello ea ho ntša mocheso e tsitsitse, 'me botenya ba phaephe e nang le mabota a masesaane bo lekana. Lebelo la ho ntša mocheso le potlakile, tlhahiso ea mofuta o butsoetsoeng e ntlafalitsoe haholo, bokaholimo bo khanya haholoanyane, 'me othomathike oa ts'ebetso o phahame.

Phaephe ea HDPE ke phaephe ea polasetiki e tenyetsehang e entsoeng ka polyethylene e nang le tekanyo e phahameng ea thermoplastic e sebelisoang haholo bakeng sa phetiso ea mokelikeli le khase mochesong o tlase. Mehleng ea morao tjena, liphaephe tsa HDPE li fumane ts'ebeliso ea tsona e kholo bakeng sa ho jara metsi a nooang, litšila tse kotsi, likhase tse fapaneng, lerōle, metsi a mollo, metsi a pula, jj. Tlamo e matla ea limolek'hule ea thepa ea phaephe ea HDPE e e thusa ho e sebelisa bakeng sa liphaephe tse nang le khatello e phahameng. Liphaephe tsa polyethylene li na le nalane e telele le e ikhethang ea ts'ebeletso bakeng sa khase, oli, merafo, metsi le liindasteri tse ling. Ka lebaka la boima ba eona bo tlase le ho hanyetsa ho hoholo ha mafome, indasteri ea liphaephe tsa HDPE e ntse e hola haholo. Ka selemo sa 1953, Karl Ziegler le Erhard Holzkamp ba ile ba sibolla polyethene e nang le tekanyo e phahameng (HDPE). Liphaephe tsa HDPE li ka sebetsa ka mokhoa o khotsofatsang mochesong o moholo oa -2200 F ho isa ho +1800 F. Leha ho le joalo, tšebeliso ea Liphaephe tsa HDPE ha e khothalletsoe ha mocheso oa mokelikeli o feta 1220 F (500 C).

Liphaephe tsa HDPE li etsoa ka ho etsa polymerization ea ethylene, e leng sehlahisoa se setseng sa oli. Li-additives tse fapaneng (li-stabilizer, li-filler, li-plasticizer, li-softeners, li-lubricant, li-colorant, li-lake retardants, li-blowing agents, li-crosslinking agents, li-additives tse senyehang ke ultraviolet, jj.) lia eketsoa ho hlahisa phaephe ea ho qetela ea HDPE le likarolo. Bolelele ba phaephe ea HDPE bo etsoa ka ho futhumatsa resin ea HDPE. Ebe e ntšoa ka die, e khethollang bophara ba phaephe. ​​Botenya ba lebota la phaephe bo khethoa ke motsoako oa boholo ba die, lebelo la sekurufu, le lebelo la terekere e hulang. Hangata, 3-5% carbon black e eketsoa ho HDPE ho e etsa hore e hanele UV, e leng se fetolang liphaephe tsa HDPE hore e be ntšo ka 'mala. Mefuta e meng ea mebala e fumaneha empa hangata ha e sebelisoe khafetsa. Phaephe ea HDPE e mebala kapa e metsero hangata ke thepa e ntšo ea 90-95%, moo mola o mebala o fanoang holim'a 5% ea bokaholimo ba kantle.
