Umugqa Wokukhipha Amapayipi e-HDPE Onga Amandla Osheshayo

Ucwaningo lwakamuva lwenkampani yethu kanye nokuthuthukiswa komugqa wokukhiqiza wesivinini esiphezulu osonga amandla, ofanelekela ukukhishwa kwamapayipi e-polyolefin ngesivinini esikhulu. Ukonga amandla okungu-35% kanye nokwanda kokusebenza kahle kokukhiqiza okuphindwe ka-1. Isakhiwo sezikulufo ze-38-40 L/D esakhelwe ngqo kanye nomgqomo wokudla kwenza imiphumela yokukhishwa kokuncibilika kanye nokwenza ipulasitiki ithuthuke kakhulu. Amabhokisi egiya anamandla aphezulu aqinisekisa ukusebenza okuzinzile kwemishini. Izikhunta ze-extrusion kanye nemikhono yosayizi kusebenzisa isakhiwo sokuklama esithuthuke kakhulu. Ithangi le-vacuum lokulawula imvamisa eguquguqukayo ye-PLC, ithrekhi yethrekhi eqhutshwa yi-servo, kanye nomsiki wesivinini esiphezulu ongenama-chip afakwe uhlelo lokulawula isisindo semitha. Isisindo sokukhishwa kwamapayipi sinembile kakhulu.

Ipayipi le-HDPE liyipayipi lepulasitiki eliguquguqukayo elenziwe nge-thermoplastic high-density polyethylene esetshenziswa kabanzi ekudlulisweni koketshezi oluyingozi kanye negesi. Muva nje, amapayipi e-HDPE athole ukusetshenziswa kwawo okukhulu ekuthwaleni amanzi aphuzwayo, imfucuza eyingozi, amagesi ahlukahlukene, udaka, amanzi omlilo, amanzi esiphepho, njll. Isibopho esinamandla sama-molecule sezinto zamapayipi e-HDPE siyasiza ekusetshenzisweni kwamapayipi anomfutho ophezulu. Amapayipi e-polyethylene anomlando omude futhi ovelele wenkonzo yegesi, uwoyela, izimayini, amanzi, kanye neminye imboni. Ngenxa yesisindo sawo esiphansi kanye nokumelana nokugqwala okuphezulu, imboni yamapayipi e-HDPE ikhula kakhulu. Ngonyaka ka-1953, uKarl Ziegler no-Erhard Holzkamp bathola i-polyethene ephezulu (HDPE). Amapayipi e-HDPE angasebenza ngendlela eyanelisayo ebangeni lokushisa elibanzi elisuka ku--2200 F kuya ku-+1800 F. Kodwa-ke, ukusetshenziswa kwamapayipi e-HDPE akukhuthazwa lapho izinga lokushisa loketshezi lidlula u-1220 F (500 C).

Amapayipi e-HDPE enziwa ngokwenziwa kwe-polymerization ye-ethylene, umkhiqizo ophuma ku-oyela. Izithasiselo ezahlukahlukene (iziqinisi, izigcwalisi, amapulasitiki, izithambisi, izinto zokugcoba, izinto zokufaka imibala, izinto ezivimbela ilangabi, izinto zokuqhuma, izinto zokuxhumanisa, izithasiselo ezibolayo ze-ultraviolet, njll.) zengezwa ukukhiqiza ipayipi lokugcina le-HDPE kanye nezingxenye. Ubude bepayipi le-HDPE benziwa ngokushisa i-resin ye-HDPE. Bese ikhishwa ngedayi, enquma ububanzi bepayipi. Ubukhulu bodonga lwepayipi bunqunywa inhlanganisela yosayizi wedayi, isivinini sesikulufu, kanye nesivinini setrekta yokudonsa. Ngokuvamile, umnyama wekhabhoni ongu-3-5% ufakwa ku-HDPE ukuze uyenze imelane ne-UV, okuguqula amapayipi e-HDPE abe mnyama ngombala. Kunezinye izinhlobo zemibala ezitholakalayo kodwa ngokuvamile azisetshenziswa njalo. Ipayipi le-HDPE elinombala noma elinemigqa ngokuvamile liyizinto ezimnyama ezingu-90-95%, lapho umugqa onombala unikezwa khona ku-5% yangaphandle.
