imikhiqizo

Izinhlaka ze-HDPE zamapayipi kathayela angamawele,
I-HDPE QHE16A, I-HDPE QHE16B,

Ibanga lepayipi le-HDPE linokusabalalisa okubanzi noma okubili kwesisindo samangqamuzana.Inokumelana okuqinile kwe-creep kanye nebhalansi enhle yokuqina nokuqina.Ihlala isikhathi eside futhi ine-sag ephansi uma icutshungulwa.Amapayipi akhiqizwa kusetshenziswa le resin anamandla amahle, ukuqina kanye nokumelana nomthelela kanye nempahla enhle kakhulu ye-SCG ne-RCP..

I-resin kufanele igcinwe endaweni yokugcina impahla, eyomile futhi kude nomlilo kanye nelanga eliqondile.Akufanele inqwabelane endaweni evulekile.Ngesikhathi sokuthutha, izinto ezisetshenziswayo akufanele zichayeke elangeni elinamandla noma imvula futhi akufanele zihanjiswe kanye nesihlabathi, inhlabathi, izinsimbi ezilahliwe, amalahle noma ingilazi.Ezokuthutha kanye

izinto ezinobuthi, ezonakalisayo futhi ezivuthayo azivunyelwe ngokuphelele.

Isicelo

Ibanga lepayipi le-HDPE lingasetshenziswa ekukhiqizeni amapayipi okucindezela, njengamapayipi amanzi anomfutho, amapayipi egesi kaphethiloli kanye namanye amapayipi ezimboni.Ingase futhi isetshenziselwe ukwenza amapayipi angacindezeli njengamapayipi kathayela anodonga oluphindwe kabili, amapayipi anodonga oluyizigodi, amapayipi e-silicon-core, amapayipi okunisela ezolimo namapayipi ayinhlanganisela ye-aluminiumplastics.Ukwengeza, ngokusebenzisa i-extrusion esebenzayo (i-silane cross-linking), ingasetshenziselwa ukukhiqiza amapayipi e-polyethylene axhunyiwe (PEX) ukuze ahlinzeke ngamanzi abandayo nashisayo.

Amapharamitha

high density polyethylene (HDPE) okukhethekile resin for twin-wall uthayela ipayipi enobubanzi obukhulu.Imiphumela ikhombisa ukuthi ama-resin akhethekile, achazwa njenge-QHE16A/B ngokulandelana, ane-modulus egoqayo ngaphezulu kwe-1150 MPa, amandla ancibilika ngaphezu kwe-1.60 MPa kanye nesikhathi sokungeniswa kwe-oxidation mayelana ne-100 min.Womabili amabanga ama-resin anokucutshungulwa okuhle futhi anelisa izidingo zokukhiqiza amapayipi kathayela anodonga olukabili emabhizinisini asekhaya.
