HDPE Pipe Extrusion Line ea lebelo le phahameng e bolokang Matla
Paramethara e ka sehloohong ea tekheniki
Tshebetso ＆ Melemo
Patlisiso ea morao-rao ea k'hamphani ea rona le nts'etsopele ea mohala oa tlhahiso ea lebelo le phahameng o bolokang matla, o loketseng ho extrusion ea phala ea polyolefin ea lebelo le holimo. 35% ea ho boloka matla le keketseho ea 1x ea katleho ea tlhahiso. Sebopeho se entsoeng ka ho khetheha sa 38-40 L / D screw le moqomo oa ho fepa o etsa hore ho qhibiliha ho qhibilihe le liphello tsa polasetiki li ntlafatse haholo. Li-gearbox tsa torque e phahameng, tse matla a phahameng li netefatsa ts'ebetso e tsitsitseng ea lisebelisoa. Li-mold tsa Extrusion le matsoho a boholo li nka sebopeho se tsoetseng pele ka ho fetisisa. Tanka ea vacuum ea PLC e feto-fetohang, terekere e tsamaeang ka li-track tse ngata e tsamaisoang ke servo, le sekhechana sa lebelo le phahameng sa chip li na le sistimi ea taolo ea boima ba mithara. Boima ba phala ea extrusion bo nepahetse haholoanyane.
Pipe ea HDPE ke phala ea polasetiki e tenyetsehang e entsoeng ka thermoplastic high-density polyethylene e sebelisoang haholo bakeng sa mokelikeli o tlase oa mocheso le phetisetso ea khase. Morao tjena, liphaephe tsa HDPE li fumane tšebeliso ea tsona e pharaletseng bakeng sa ho tsamaisa metsi a nooang, litšila tse kotsi, likhase tse fapa-fapaneng, seretse, metsi a mollo, metsi a sefefo, joalo-joalo. Bond e matla ea molek'hule ea thepa ea liphaephe tsa HDPE e e thusa ho sebelisa liphaephe tse phahameng tsa khatello. Lipeipi tsa polyethylene li na le nalane e telele ea ts'ebeletso e ikhethang bakeng sa khase, oli, merafo, metsi le liindasteri tse ling. Ka lebaka la boima ba eona bo tlase le khanyetso e phahameng ea kutu, indasteri ea lipeipi tsa HDPE e ntse e hola haholo. Ka selemo sa 1953, Karl Ziegler le Erhard Holzkamp ba ile ba sibolla polyethene e phahameng haholo (HDPE). Liphaephe tsa HDPE li ka sebetsa ka mokhoa o khotsofatsang mocheso o pharaletseng oa -2200 F 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 entsoe ka polymerization ea ethylene, sehlahisoa sa oli. Li-additives tse fapaneng (li-stabilizer, li-filler, li-plasticizers, li-softeners, lubricant, li-colorants, li-flame retardants, li-agent tse buloang, li-crosslinking, li-additives tse senyehang tsa ultraviolet, joalo-joalo) li kenngoa ho hlahisa phala ea ho qetela ea HDPE le likaroloana. Bolelele ba liphaephe tsa HDPE bo entsoe ka ho futhumatsa resin ea HDPE. Ka mor'a moo, e fetisetsoa ka thapo, e leng se khethollang bophara ba pipeline. Botenya ba lerako la Pipe bo laolwa ke motswako wa boholo ba die, lebelo la screw, le lebelo la terekere e hulang. Hangata, 3-5% ea carbon black e kenngoa ho HDPE ho e etsa hore e hanyetse UV, e fetolang liphaephe tsa HDPE hore e be tse ntšo ka 'mala. Mefuta e meng ea mebala e teng empa hangata ha e sebelisoe khafetsa. Peipi ea HDPE e mebala-bala kapa e metsero hangata ke 90-95% e ntšo, moo mola o mebala o fanoang ka 5% ea kantle.
