I-HDPE Ubushushu boMbhobho we-Extrusion Line

I-HDPE Ubushushu boMbhobho wokuKhulisa umbhobho we-HDPE oFakelweyo nguMfanekiso

Inkcazelo emfutshane:

Umbhobho wokugquma we-PE ukwabizwa ngokuba yi-PE umbhobho wokukhusela wangaphandle, umbhobho webhatyi, umbhobho wemikhono. Umbhobho wokugquma we-polyurethane ongcwatywe ngokuthe ngqo wenziwa ngombhobho wokugquma we-HDPE njengomaleko okhuselayo wangaphandle, i-foam ephakathi ezaliswe yi-polyurethane eqinile isetyenziswa njengomaleko wezinto zokugquma, kwaye umaleko wangaphakathi ngumbhobho wentsimbi. I-polyure-thane ngqo engcwatywa umbhobho wokugquma uneempawu ezilungileyo zoomatshini kunye nokusebenza kokufakelwa kwe-thermal. Phantsi kweemeko eziqhelekileyo, inokumelana nobushushu obuphezulu be-120-180 °C, kwaye ilungele iiprojekthi ezahlukeneyo zokugquma imibhobho yamanzi abandayo nashushu.

I-HDPE Ubushushu boMbhobho we-Extrusion Line

Ukusebenza kunye neempawu

Umgca wokuvelisa umbhobho we-insulation uyilwe kunye ne-PE ekhethekileyo yokubumba umbhobho we-insulation, uxinzelelo lwe-extrusion luzinzile, kwaye ubukhulu bombhobho obhityileyo bufana. Isantya se-extrusion sikhawuleza, imveliso yohlobo oluvuthelweyo iphuculwe kakhulu, umphezulu uqaqambile, kwaye i-automation yokusebenza iphezulu.

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.
