Umgca Wokukhutshelwa Kwepayipi Ye-HDPE Eyonga Amandla Ngesantya Esiphezulu

Uphando lwamva nje lwenkampani yethu kunye nophuhliso lomgca wemveliso ogcina amandla ngesantya esiphezulu, ofanelekileyo kwi-extrusion yepayipi ye-polyolefin enesantya esiphezulu. Ukonga amandla ngama-35% kunye nokwanda kokusebenza kakuhle kwemveliso nge-1x. Ulwakhiwo lwezikrufu eziyilwe ngokukodwa ezingama-38-40 L/D kunye ne-feeding slot barrel zenza ukuba i-melt extrusion kunye ne-plasticizing ziphuculwe kakhulu. Iibhokisi zegiya ezinamandla aphezulu ziqinisekisa ukusebenza okuzinzileyo kwezixhobo. Ii-Extrusion molds kunye nee-size sleeves zamkela uyilo oluphambili. I-PLC variable frequency control vacuum tank, i-servo-driven multi-track track, kunye ne-high-speed chip-less cutter zixhotyiswe ngenkqubo yokulawula ubunzima bemitha. Ubunzima be-pipe extrusion buchaneke ngakumbi.

Umbhobho we-HDPE ngumbhobho weplastiki oguquguqukayo owenziwe nge-polyethylene ephezulu ye-thermoplastic esetyenziswa kakhulu ekudluliseleni ulwelo oluphantsi kobushushu kunye negesi. Kutshanje, imibhobho ye-HDPE ifumene ukusetyenziswa kwayo okukhulu ekuthwaleni amanzi okusela, inkunkuma enobungozi, iigesi ezahlukeneyo, udaka, amanzi omlilo, amanzi emvula, njl. Ukubopha okuqinileyo kwe-molecular yezixhobo zepayipi ye-HDPE kuyinceda ukuba isebenzise imibhobho ephezulu. Imibhobho ye-polyethylene inembali ende nebalaseleyo yenkonzo yegesi, ioyile, imigodi, amanzi, kunye neminye imboni. Ngenxa yobunzima bayo obuphantsi kunye nokumelana nokugqwala okuphezulu, ishishini lemibhobho ye-HDPE likhula kakhulu. Ngonyaka we-1953, uKarl Ziegler no-Erhard Holzkamp bafumanise i-polyethene ephezulu (HDPE). Imibhobho ye-HDPE ingasebenza ngokwanelisayo kuluhlu olubanzi lobushushu ukusuka kwi--2200 F ukuya kwi-+1800 F. Nangona kunjalo, ukusetyenziswa kweMibhobho ye-HDPE akucetyiswa xa ubushushu bolwelo budlula i-1220 F (500 C).

Iipayipi ze-HDPE zenziwa ngokupholimetha i-ethylene, imveliso ephuma kwioyile. Izongezo ezahlukeneyo (izinzisi, izizalisi, iiplastiki, izithambisi, izithambisi, izinto zokufaka imibala, izinto ezithintela ilangatye, izinto ezivuthuzayo, izinto ezidibanisayo, izongezo ezinokubola nge-ultraviolet, njl.njl.) zongezwa ukuvelisa umbhobho wokugqibela we-HDPE kunye nezinto. Ubude bepayipi ye-HDPE benziwa ngokufudumeza i-resin ye-HDPE. Emva koko ikhutshwa ngedayi, emisela ububanzi bombhobho. Ubukhulu bodonga lwepayipi bumiselwa kukudibanisa ubungakanani bedayi, isantya sesikrufu, kunye nesantya setrekta yokuthutha. Ngokwesiqhelo, i-3-5% yekhabhoni emnyama yongezwa kwi-HDPE ukuyenza ingangeni kwi-UV, nto leyo eguqula iipayipi ze-HDPE zibe mnyama ngombala. Kukho ezinye iintlobo zemibala kodwa azisetyenziswa rhoqo. Umbhobho we-HDPE onemibala okanye onemigca uhlala uyinto emnyama engama-90-95%, apho umgca onemibala unikezelwa kwi-5% yangaphandle.
