imikhiqizo

I-HDPE resin yepayipi likathayela elinezindonga ezimbili,
I-HDPE resin ye-bellow, I-HDPE resin yezimbongolo ezinodonga oluphindwe kabili,

Ngenxa yokusebenza kahle kakhulu kwepayipi likathayela elinodonga oluphindwe kabili lwe-HDPE, ngokuthuthuka ngokushesha komphakathi, kancane kancane selingene esikhundleni sepayipi lendabuko, okulethe ukunethezeka okukhulu empilweni yabantu.Lokhu kungenxa yokuthi ipayipi likathayela le-HDPE elinodonga oluphindwe kabili liphephile futhi lifaneleka kakhulu kunepayipi lensimbi elivamile kanye nepayipi likakhonkolo ezicini eziningi, futhi lamukelwa ngamaphrojekthi wokwakha futhi lisetshenziswa kabanzi kakhulu kumaphrojekthi amapayipi ahlukahlukene.

Namuhla, ake sichaze ngokuningiliziwe ukuthi yiziphi izinzuzo ze-HDPE ezinodonga oluphindwe kabili?

1. Ipayipi likathayela elinezindonga ezimbili ze-HDPE linokumelana okuqinile kokucindezela.I-hdpe-double-wall bellows inamandla amakhulu okucindezela kune-bellows yendabuko ngaphansi kwezimo ezifanayo zengcindezi.Ngenxa yokwakhiwa kwesimo esiyingqayizivele, udonga lwayo lwangaphandle lufakwe uthayela, olungakhuphula ukuqina kwendandatho yepayipi, inikeze ukumelana okuqinile nokucindezela kwangaphandle.

2, ipayipi likathayela le-HDPE elinodonga oluphindwe kabili linomsebenzi obiza kakhulu.Ngaphansi komthwalo ofanayo, ipayipi likathayela elinezindonga ezimbili ze-HDPE lidinga kuphela ukuhlangabezana nezidingo zodonga lwamapayipi amancane, izinto ezingavuthiwe zamanye amapayipi kuphela ezingasetshenziswa, uma kuqhathaniswa nezindleko zokonga izindleko zobunjiniyela.Lesi ngesinye sezizathu zokuthi kungani amaphrojekthi amaningi namuhla ayikhetha.

I-3, isivinini sokwakhiwa kwe-HDPE yezindonga ezimbili siyashesha.Ngenxa yodonga oluncane lwe-HDPE olunezimbongolo eziphindwe kabili, ohlelweni lokwakha, kungakhathaliseki ukuthi luyalayisha futhi luyathulula noma luyaxhunywa, lulula kakhulu kunepayipi lendabuko, futhi ukulungiswa kwakamuva kulula.Uma isendaweni eyakhiwe kanzima, ingabonisa izinzuzo ze-HDPE enezindonga eziphindwe kabili.

Lezi yizici ze-HDPE ezinezindonga eziphindwe kabili, ngoba ziyikhemikhali yokukhiqiza ipayipi lepulasitiki, inokuguquguquka okuhle, kanye nezakhiwo zemvelo, ngakho-ke, ingasetshenziswa kabanzi kubunjiniyela bamapayipi.

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.Ukuhamba nezinto ezinobuthi, ezonakalisayo nezivuthayo akuvunyelwe 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.
