iimveliso

I-resin ye-HDPE yokuvelisa umbhobho,
HDPE resin for imibhobho, HDPE ibakala lombhobho resin, HDPE resin umboneleli,

Ibakala lombhobho we-HDPE linokusabalalisa okubanzi okanye kwe-bimodal ubunzima be-molecular.Inoxhathiso oluqinileyo lwe-creep kunye nokulinganisela okulungileyo kokuqina kunye nokuqina.Yomelele kakhulu kwaye ine-sag ephantsi xa isenziwa.Imibhobho eveliswa kusetyenziswa le resin inamandla amahle, ukuqina kunye nokumelana nempembelelo kunye nepropathi egqwesileyo ye-SCG kunye ne-RCP.

I-resin kufuneka igcinwe kwindawo yokugcina impahla, eyomileyo kwaye kude nomlilo kunye nelanga elithe ngqo.Akufunekanga ifunjwe kwindawo evulekileyo.Ngexesha lokuthutha, izinto eziphathekayo akufanele zibekwe kwilanga elinamandla okanye imvula kwaye akufanele zihanjiswe kunye nesanti, umhlaba, isinyithi esilahliweyo, amalahle okanye iglasi.Uthutho kunye nezinto eziyityhefu, ezidlekayo nezinokutsha akuvumelekanga ngokungqongqo.

Isicelo

Inqanaba lombhobho we-HDPE lingasetyenziselwa ukuveliswa kwemibhobho yoxinzelelo, njengemibhobho yamanzi ecinezelekileyo, imibhobho yegesi yepetroli kunye neminye imibhobho yoshishino.Isenokusetyenziswa ukwenza imibhobho engacinezelekiyo njengemibhobho etyatyiweyo enodonga oluphindwe kabini, imibhobho yodonga olunomngxuma, imibhobho yesilicon-core, imibhobho yokunkcenkceshela yezolimo kunye nemibhobho edityanisiweyo ye-aluminiyamplastics.Ukongeza, nge-extrusion esebenzayo (i-silane cross-linking), ingasetyenziselwa ukuvelisa imibhobho ye-polyethylene edibeneyo (PEX) yokubonelela ngamanzi abandayo nashushu.

Amabanga kunye nexabiso eliqhelekileyo

I-HDPE yikristale ephezulu, i-non-polar thermoplastic resin.Imbonakalo ye-HDPE yoqobo imhlophe qhwa, iqondo elithile lokuguquguquka kwicandelo elibhityileyo.I-PE inokumelana okugqwesileyo koninzi lweekhemikhali zasekhaya nezamashishini.Iindidi ezithile zeekhemikhali zinokubangela ukubola kweekhemikhali, ezifana ne-corrosive oxidants (concentrated nitric acid), iihydrocarbons ezinuka kamnandi (xylene) kunye nehalogenated hydrocarbons (carbon tetrachloride).I-polymer ayinayo i-hygroscopic kwaye inokumelana kakuhle ne-steam, engasetyenziselwa iinjongo zokupakisha.I-HDPE inezixhobo zombane ezilungileyo kakhulu, ngakumbi amandla aphezulu e-dielectric yokugquma, ukuze ifaneleke kakhulu kwingcingo kunye nentambo.Phakathi ukuya kwiiklasi eziphezulu zemolekyuli zinefuthe elihle kakhulu lokuchasa kwiqondo lobushushu begumbi kunye nakwiqondo lobushushu elisezantsi njenge -40F.

Imiba efuna ingqalelo ekusetyenzisweni kombhobho we-HDPE

I-1, ukubekwa ngaphandle kwe-air open-air, apho kukho ukukhanya kwelanga, kuyacetyiswa ukuba wenze imilinganiselo yokukhusela.

2. Umbhobho wonikezelo lwamanzi we-HDPE engcwatyiweyo, umbhobho we-DN≤110 unokufakwa ehlotyeni, ukubekwa kwenyoka kancinci, umbhobho we-DN≥110 ngenxa yokuxhathisa okwaneleyo komhlaba, unokumelana noxinzelelo lwe-thermal, akukho mfuneko yokugcina umbhobho ubude;Ebusika, akukho mfuneko yokugcina ubude bombhobho.

I-3, ukufakwa kombhobho we-HDPE, ukuba indawo yokusebenza incinci kakhulu (efana ne: umbhobho kakuhle, ukwakhiwa kwesilingi, njl.), kufuneka kusetyenziswe ukudibanisa ukudibanisa kombane.

4. Xa i-socket eshushu enyibilikayo idityanisiwe, ubushushu bokufudumala akufanele buphakame kakhulu okanye bubude kakhulu, kwaye ubushushu kufuneka bulawuleke kwi-210±10℃, kungenjalo kuya kubangela udaka olutyhidiweyo olugqithisiweyo kwiindawo kwaye lunciphise ngaphakathi. ububanzi bamanzi;Umbhobho wokudibanisa okanye umbhobho odibeneyo kufuneka uhlambuluke xa i-socket ifakwe, ngaphandle koko iya kubangela ukuba i-socket iphule kwaye ivuze;Ngelo xesha, ingqalelo kufuneka ihlawulwe ukulawula i-Angle kunye nesikhokelo sokufakelwa kombhobho ukuphepha ukusebenza kwakhona.

5, uqhagamshelo olushushu lwe-butt, i-voltage iyafuneka phakathi kwe-200 ~ 220V, ukuba i-voltage iphezulu kakhulu, iya kubangela ukuba ukushisa kwepleyiti yokufudumeza kuphezulu kakhulu, i-voltage iphantsi kakhulu, ngoko umatshini we-butt awukwazi ukusebenza ngokuqhelekileyo;Impundu kufuneka ilungelelaniswe kujongano;ngaphandle koko, indawo ye-butt ayanele, amandla e-welding joint akwanele, kwaye i-flange ayilungile.Xa i-plate yokufudumeza ishushu, i-interface yombhobho ayicocwa, okanye i-plate yokufudumala inokungcola okufana neoli kunye ne-sediment, eya kubangela ukuba i-interface iphuke kwaye ivuze.Ixesha lokufudumeza kufuneka lilawulwe kakuhle.Ixesha elifutshane lokufudumeza kunye nexesha elaneleyo lokufunxa ukushisa kombhobho kuya kubangela ukuba i-welding seam ibe yincinci kakhulu.Ixesha elide lokufudumeza liya kubangela ukuba i-welding seam ibenkulu kakhulu kwaye inokwenza i-welding ebonakalayo.
