Mohala oa ho Ntša Phaephe ea HDPE e Bolokang Matla ka Lebelo le Phahameng

Patlisiso ea morao-rao ea k'hamphani ea rona le nts'etsopele ea mohala oa tlhahiso o bolokang matla o lebelo le phahameng, o loketseng ho ntša phaephe ea polyolefin ka lebelo le phahameng. Ho boloka matla ka 35% le keketseho ea 1x ea katleho ea tlhahiso. Sebopeho sa sekurufu sa 38-40 L/D se entsoeng ka ho khetheha le moqomo oa sebaka sa ho fepa li etsa hore litlamorao tsa ho ntša metsi le ho etsa polasetiki li ntlafale haholo. Li-gearbox tse nang le torque e phahameng, tse matla a phahameng li netefatsa ts'ebetso e tsitsitseng ea lisebelisoa. Li-mold tsa extrusion le matsoho a boholo li amohela sebopeho sa moralo se tsoetseng pele ka ho fetisisa. Tanka ea vacuum ea taolo ea maqhubu a feto-fetohang a PLC, terekere e tsamaisoang ke servo-multi-track, le sehahi se se nang chip se lebelo le phahameng li na le sistimi ea taolo ea boima ba mithara. Boima ba ho ntša metsi ka phaephe bo nepahetse haholoanyane.

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 ho 5% ea kantle.
