imikhiqizo

I-HDPE resin yokukhiqiza amapayipi,
I-HDPE resin yamapayipi, Ibanga lepayipi le-resin le-HDPE, Umhlinzeki we-resin we-HDPE,

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.

Amabanga nenani elijwayelekile

I-HDPE iyi-crystallinity ephezulu, i-non-polar thermoplastic resin.Ukubukeka kwe-HDPE yasekuqaleni kumhlophe qhwa, izinga elithile lokuguquguquka esigabeni esincanyana.I-PE inokumelana okuhle kakhulu namakhemikhali amaningi asekhaya nawemboni.Izinhlobo ezithile zamakhemikhali zingabangela ukugqwala kwamakhemikhali, njengama- corrosive oxidants (concentrated nitric acid), ama-hydrocarbon anuka kamnandi (xylene) nama-halogenated hydrocarbons (carbon tetrachloride).I-polymer ayiyona i-hygroscopic futhi inokumelana okuhle kwe-steam, engasetshenziselwa izinjongo zokupakisha.I-HDPE inezinto zikagesi ezinhle kakhulu, ikakhulukazi amandla aphezulu e-dielectric of insulation, ukuze ilungele kakhulu izintambo nekhebula.Amakilasi esisindo samangqamuzana aphakathi nendawo ukuya phezulu anokumelana nomthelela omuhle kakhulu ezingeni lokushisa elivamile ngisho nasemazingeni okushisa aphansi njenge -40F.

Izindaba ezidinga ukunakwa ekusetshenzisweni kwepayipi le-HDPE

1, indawo evulekile yangaphandle, lapho kunokukhanya kwelanga, kunconywa ukwenza izinyathelo zokukhosela.

2. Ipayipi lokuphakelwa kwamanzi le-HDPE elingcwatshwe, ipayipi DN≤110 lingafakwa ehlobo, ukubeka inyoka kancane, ipayipi le-DN≥110 ngenxa yokumelana okwanele kwenhlabathi, lingamelana nokucindezeleka okushisayo, asikho isidingo sokugcina ubude bepayipi;Ebusika, asikho isidingo sokugcina ubude bepayipi.

3, ukufakwa kwepayipi le-HDPE, uma indawo yokusebenza incane kakhulu (njengokuthi: ipayipi kahle, ukwakhiwa kosilingi, njll.), kufanele kusetshenziswe ukuxhunywa kukagesi.

4. Lapho isokhethi encibilikayo eshisayo ixhunyiwe, izinga lokushisa lokushisa akufanele libe phezulu kakhulu noma libe lide kakhulu, futhi izinga lokushisa kufanele lilawulwe ku-210±10℃, ngaphandle kwalokho lizobangela udaka oluncibilikisiwe oluningi kakhulu ezingxenyeni futhi lunciphise ingaphakathi. ububanzi bamanzi;Ukufakwa kwepayipi noma ukuhlanganiswa kwepayipi kufanele kuhlanzeke lapho isokhethi ifakiwe, ngaphandle kwalokho kuzokwenza ukuthi isokhethi liphule futhi livuze;Ngesikhathi esifanayo, ukunakwa kufanele kukhokhwe ukulawula i-Angle kanye nesiqondiso sokufakwa kwamapayipi ukuze kugwenywe ukusebenza kabusha.

I-5, i-hot melt butt uxhumano, i-voltage iyadingeka phakathi kuka-200 ~ 220V, uma i-voltage iphezulu kakhulu, izobangela izinga lokushisa lepuleti lokushisa liphezulu kakhulu, i-voltage iphansi kakhulu, khona-ke umshini wezinqe awukwazi ukusebenza ngokujwayelekile;I-butt kufanele iqondaniswe nesixhumi esibonakalayo;uma kungenjalo, indawo ye-butt ayanele, amandla okuhlanganyela okushisela ayanele, futhi i-flange ayilungile.Lapho ipuleti lokushisa lishiswa, i-interface yepayipi ayihlanzwa, noma ipuleti lokushisa linokungcola okufana namafutha kanye ne-sediment, okuzokwenza ukuthi isikhombimsebenzisi siphuke futhi sivuze.Isikhathi sokushisa kufanele silawulwe kahle.Isikhathi esifushane sokushisa kanye nesikhathi esinganele sokumunca ukushisa kwepayipi kuzobangela ukuthi i-welding seam ibe mncane kakhulu.Isikhathi sokushisisa eside kakhulu sizobangela ukuthi umthungo wokushisela ube mkhulu kakhulu futhi ungase wakhe i-virtual welding.
