Kushandiswa kwePE Pipe

1. PE yekuchera pombi
Pakati pemapurasitiki einjiniya ese, HDPE ine yakanyanya kupfeka kuramba uye ndiyo inonyanya kuoneka. Kukwirisa huremu hwemamorekuru, ndipo panobva panyanya kusapfeka zvinhu, kunyange kudarika zvinhu zvakawanda zvesimbi (senge kabhoni simbi, simbi isina tsvina, bhuronzi, nezvimwewo). Pasi pemamiriro ekuora kwakasimba uye kupfeka kwepamusoro, hupenyu hwebasa ndeye 4-6 nguva yepombi yesimbi uye 9 nguva yepolyethylene yakajairika; Uye kugona kwekufambisa kunovandudzwa ne20%. Iyo inodzoreredza murazvo uye antistatic zvivakwa zvakanaka uye zvinosangana nezvinodiwa zvakajairwa. Hupenyu hwesevhisi yehupfu hwakapfuura makore makumi maviri, iine mabhenefiti anoshamisa ehupfumi, kupikisa kwemaitiro, kuramba kupfeka uye kuramba kaviri.

2. PE sewage pombi
PE pombi yekurasa tsvina inonziwo high density polyethylene pipe, zvinoreva HDPE muChirungu. Iri rudzi rwepombi rinowanzoshandiswa seyekutanga sarudzo yeinjiniya yemanisipala, inonyanya kushandiswa muindasitiri yekuchenesa tsvina. Nekuda kwekupfeka kwayo, acid resistance, corrosion resistance, tembiricha yakakwira, high pressure resistance uye humwe hunhu, zvishoma nezvishoma yakatsiva nzvimbo yemapombi echinyakare semapombi esimbi nemapombi esimende pamusika, kunyanya nekuti pombi iyi ine huremu huremu. uye yakanakira kuisa nekufambisa, uye ndiyo yekutanga sarudzo yezvinhu zvitsva. Vashandi vanofanira kunyatsocherechedza pfungwa dzinotevera pakusarudza mapaipi akagadzirwa nechinhu ichi: 1. Nyatsoteerera kusarudzwa kwezvinhu zvakasvibiswa zvepombi dzepurasitiki. Kune zviuru zvemagiredhi e polyethylene raw materials, uye kune mbishi zvinhu zvakaderera sezviuru zveyuan patani pamusika. Zvigadzirwa zvinogadzirwa neiyi mbishi zvinhu hazvigone kuvakwa, zvikasadaro, rework kurasikirwa kuchave kwakakura. 2. Kusarudzwa kwevagadziri vemapaipi kuchave pasi pevagadziri vepamutemo uye vane hunyanzvi. 3. Paunenge uchisarudza kutenga mapaipi ePE, tarisa vagadziri panzvimbo yacho kuti uone kana vane simba rekugadzira.

3. Pombi yemvura yePE
Mapombi ePE ekugovera mvura ndiwo anotsiviwa nepombi dzesimbi dzechinyakare uye mapaipi emvura ekunwa ePVC.
Iyo pombi yekupa mvura inofanirwa kutakura kumwe kudzvanywa, uye PE resin ine huremu hwemamorekuru uye yakanaka michina zvinhu, senge HDPE resin, inowanzosarudzwa. LDPE resin ine yakaderera kusimba simba, kushomeka kudzvinyirira kuramba, kushomeka kusimba, kuderera kwechimiro chakadzikama panguva yekuumbwa uye yakaoma yekubatanidza, saka haina kukodzera sechinhu chemvura yekumanikidza pombi. Nekudaro, nekuda kweiyo yakakwira hutsanana index, PE, kunyanya HDPE resin, yave chinhu chakajairika kugadzira pombi dzemvura yekunwa. HDPE resin ine yakaderera melt viscosity, yakanaka fluidity uye nyore kugadzirisa, saka iyo yakanyunguduka index ine dzakasiyana siyana dzesarudzo, kazhinji iyo MI iri pakati pe0.3-3g / 10min.
