I-HDPE Pipe Extrusion Line enesivinini esikhulu yokonga Amandla

Ucwaningo lwakamuva lwenkampani yethu kanye nokuthuthukiswa kolayini wokukhiqiza wejubane eliphezulu owonga amandla, olungele ukukhishwa kwepayipi le-polyolefin elinesivinini esikhulu. 35% ukonga amandla kanye nokukhuphuka oku-1x ekusebenzeni kahle kokukhiqiza. Isakhiwo sesikulufu esiklanywe ngokukhethekile esingu-38-40 L/D kanye nomgqomo we-slot wokuphakelayo kwenza ukuncibilika kwe-extrusion kanye nemiphumela yokwenza ipulasitiki ibe ngcono kakhulu. Ama-gearbox anetorque ephezulu, anamandla amakhulu aqinisekisa ukusebenza okuzinzile kwemishini. Isikhunta se-Extrusion kanye nemikhono yokulinganisa yamukela ukwakheka okuthuthuke kakhulu. Ithangi levacuum elishintshashintshayo le-PLC, ugandaganda onamathrekhi amaningi oshayelwa yi-servo, kanye ne-high-speed chip-less cutter kufakwe uhlelo lokulawula isisindo samamitha. Isisindo se-extrusion yepayipi sinembe kakhulu.

Ipayipi le-HDPE liyipayipi 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 ekuthwaleni 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, okokugcoba, okombala, izinqamuli zomlilo, izinto ezifuthayo, ama-crosslinking agents, 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 liyimpahla emnyama engu-90-95%, lapho umugqa onemibala unikezwa ku-5% ngaphandle.
