HDPE Heat Insulation Pipe Extrusion Line
Paramethara e ka sehloohong ea tekheniki
Tshebetso le likarolo
Mohala oa tlhahiso ea lipeipi tsa insulation o entsoe ka hlobo e khethehileng ea PE ea ho kenya phala, khatello ea extrusion e tsitsitse, 'me botenya ba phala e tšesaane e nang le marako ke junifomo. Lebelo la extrusion le potlakile, tlhahiso ea mofuta o fefotsoeng e ntlafatsoa haholo, bokaholimo bo khanya haholoanyane, 'me opereishene ea opereishene e phahame.
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 bokantle bo ka ntle.
