I-Silicon Coating Pipe Extrusion Line

Ulayini wokukhiqiza ungabona amapayipi ayisisekelo amaningi ngesikhathi esisodwa, ukuqaqa isivinini esikhulu, futhi umboze ngokushesha nangokulinganayo ikesi yangaphandle.I-synchronous traction, i-cut-cut off kanye ne-coiling yomkhiqizo oqediwe kulawulwa yikhompyutha, ngesivinini sokukhiqiza esiphezulu nokusebenza kahle.

Ipayipi le-HDPE ipayipi lepulasitiki eliguquguqukayo elenziwe nge-thermoplastic high-density polyethylene esetshenziselwa kabanzi uketshezi olunezinga lokushisa eliphansi kanye nokudluliswa kwegesi.Ezikhathini zamuva nje, amapayipi e-HDPE athole ukusetshenziswa kwawo okubanzi ekuphatheni amanzi aphuzwayo, imfucumfucu eyingozi, amagesi ahlukahlukene, udaka, amanzi omlilo, amanzi emvula, njll. Isibopho esiqinile samangqamuzana ezinto zamapayipi e-HDPE ayasiza ukuthi asetshenziselwe amapayipi anengcindezi ephezulu.Amapayipi e-polyethylene anomlando omude futhi ohlukile wesevisi yegesi, uwoyela, izimayini, amanzi, nezinye izimboni.Ngenxa yesisindo sayo esiphansi kanye nokumelana nokugqwala okuphezulu, imboni yamapayipi e-HDPE ikhula kakhulu.Ngonyaka ka-1953, u-Karl Ziegler no-Erhard Holzkamp bathola i-high-density polyethene (HDPE).Amapayipi e-HDPE angasebenza ngendlela egculisayo ebangeni lokushisa elibanzi elingu--2200 F kuya ku-+1800 F. Nokho, ukusetshenziswa kwamapayipi e-HDPE akuphakanyiswa lapho izinga lokushisa loketshezi lidlula i-1220 F (500 C).

Amapayipi e-HDPE enziwa yi-polymerization ye-ethylene, umkhiqizo wamafutha.Izithasiselo ezihlukahlukene (izinza, izigcwalisi, izinto zepulasitiki, izinto ezithambisayo, okothambisa, okombala, izinqamuli zomlilo, izinto ezifuthayo, ama-crosslinking, izithasiselo ezibolayo ze-ultraviolet, njll.) zengezwa ukuze kukhiqizwe ipayipi nezingxenye zokugcina ze-HDPE.Ubude bepayipi le-HDPE benziwa ngokushisisa i-resin ye-HDPE.Khona-ke ikhishwa nge-die, enquma ububanzi bepayipi.Ukujiya kodonga lwepayipi kunqunywa inhlanganisela yosayizi wokufa, isivinini sesikulufu, kanye nesivinini sikagandaganda wokudonsa.Ngokuvamile, u-3-5% wekhabhoni emnyama yengezwa ku-HDPE ukuze ikwazi ukumelana ne-UV, eshintsha amapayipi e-HDPE abe mnyama ngombala.Ezinye izinhlobo zemibala ziyatholakala kodwa ngokuvamile azisetshenziswa njalo.Ipayipi le-HDPE elinombala noma elinemigqa ngokuvamile liyi-90-95% yezinto ezimnyama, lapho umugqa onemibala unikezwa ku-5% wendawo yangaphandle.
