Mohala o moholo oa Diameter HDPE Pipe Extrusion Line

Pipe ea HDPE ke mofuta oa phala ea polasetiki e tenyetsehang e sebelisetsoang phetisetso ea mokelikeli le khase, 'me hangata e sebelisoa ho nkela konkreite e tsofetseng sebaka kapa liphaephe tsa tšepe tse kholo. E entsoe ho tloha thermoplastic HDPE (polyethylene e phahameng-e phahameng), boemo ba eona bo phahameng ba ho se hlolehe le tlamo e matla ea limolek'hule e etsa hore e tšoanelehe bakeng sa liphaephe tse phahameng tsa khatello. Peipi ea HDPE e sebelisoa lefatšeng ka bophara bakeng sa lits'ebetso tse joalo ka likhoele tsa metsi, likhoele tsa khase, likhoele tsa likhoerekhoere, likhoele tsa ho fetisoa ha seretse, nosetso ea mahaeng, likhoele tsa phepelo ea litsamaiso tsa mollo, kotopo ea motlakase le likhokahano, le lipeipi tsa metsi a sefefo le tsa drainage.

Liphaephe tse kholo tsa bophara ba HDPE li thata, li bobebe, li tšohile ebile ha li na lik'hemik'hale. Ba fana ka moruo oa ho kenya le bophelo bo bolelele ba tšebeletso. Liphaephe tsena li fumaneha ka bolelele bo tloaelehileng ba 3, 6, 12 le 14m. Bolelele bo khethehileng ba liphaephe bo ka hlahisoa ho fihlela litlhoko leha e le life.

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 ea 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 har'a sekoti, 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 bokantle bo ka ntle.
