Silicon Coating Umbhobho Extrusion Line

Umgca wemveliso unokuqonda imibhobho yesiseko emininzi ngexesha elinye, ukukhulula isantya esiphezulu, kwaye ngokukhawuleza nangokulinganayo ukuvala i-casing yangaphandle. I-synchronous traction, i-cut-off kunye ne-coiling yemveliso egqityiweyo ilawulwa yikhompyutheni, kunye nesantya esiphezulu sokuvelisa kunye nokusebenza kakuhle.

Umbhobho we-HDPE ngumbhobho weplastiki oguquguqukayo owenziwe nge-thermoplastic high-density polyethylene esetyenziswa ngokubanzi kubushushu obuphantsi kunye nokudluliselwa kwegesi. Kutshanje, imibhobho ye-HDPE ifumene ukusetyenziswa okubanzi kokuthwala amanzi okusela, inkunkuma eyingozi, iigesi ezahlukeneyo, uludaka, amanzi omlilo, amanzi esitshi, njl. Imibhobho yePolyethylene inembali ende neyohlukileyo yenkonzo yerhasi, ioyile, imigodi, amanzi, kunye namanye amashishini. Ngenxa yobunzima bayo obuphantsi kunye nokumelana nokukhula okuphezulu, ishishini lombhobho we-HDPE likhula kakhulu. Ngonyaka ka-1953, uKarl Ziegler kunye no-Erhard Holzkamp bafumana i-polyethene ephezulu yoxinaniso (HDPE). Imibhobho ye-HDPE inokusebenza ngokwanelisayo kuluhlu olubanzi lobushushu ukusuka -2200 F ukuya +1800 F. Nangona kunjalo, ukusetyenziswa kweMibhobho ye-HDPE akukhuthazwa xa ubushushu bolwelo budlula i-1220 F (500 C).

Iipayipi ze-HDPE zenziwe nge-polymerization ye-ethylene, imveliso yeoli. Izongezelelo ezahlukeneyo (izinzisi, izihluzi, iiplastiki, izithambisa, izithambisi, ii-colorants, iiretardants zomlilo, ii-agent ezivuthelayo, i-crosslinking agents, i-ultraviolet izongezo ezonakaliswayo, njl. njl.) zongezwa ukuvelisa umbhobho wokugqibela we-HDPE kunye namacandelo. Ubude bombhobho we-HDPE benziwa ngokufudumeza i-resin ye-HDPE. Emva koko ikhutshwe ngokufa, echaza ububanzi bombhobho. Ubukhulu bodonga lombhobho bumiselwa yindibaniselwano yobukhulu bokufa, isantya sesikrufu, kunye nesantya setrektara yokutsala. Ngesiqhelo, i-3-5% yekhabhoni emnyama yongezwa kwi-HDPE ukuze ikwazi ukumelana ne-UV, ejika imibhobho ye-HDPE ibemnyama ngombala. Ezinye iintlobo zemibala ziyafumaneka kodwa azisetyenziswa rhoqo. Umbhobho we-HDPE enemibala okanye enemigca idla ngokuba yi-90-95% yezinto ezimnyama, apho umgca wombala unikezelwa kwi-5% yendawo yangaphandle.
