Mutsetse weKuburitsa Pombi: Ziva Kupa Mvura uye Mapaipi Emvura

Kune mhando dzakawanda dzemapaipi anoshandiswa mumapurojekiti ekupa mvura uye ekudhonza mvura. Chinyorwa chino chinotsanangura mapaipi gumi nematanhatu anowanzo shandiswa uye chinoataura zvizere.

1. Pipe yePVC-U yakaoma

Pombi yePVC-U yakagadzirwa ne sanitary polyvinyl chloride (PVC) resin sezvinhu zvikuru, ichiwedzera huwandu hwakakodzera hwe stabilizer, lubricant, filler, color enhancer, nezvimwewo, zvinoburitswa ne plastic extruder uye injection molding machine, kuburikidza nekutonhodza, kusimba, kuumba, kuongorora, kurongedza uye mamwe maitiro ekupedzisa kugadzirwa kwemapombi nezvishandiso.

Zvakanakira mapaipi ePVC-U: huremu hushoma, kuramba ngura, kuramba kuyerera kwemvura kudiki, kuchengetedza simba, kukurumidza kuisa, uye mutengo wakaderera.

Mashandisirwo azvo: mapurojekiti emvura yemupombi mumaguta, kuvaka mapurojekiti emvura emukati nekunze, mapurojekiti emvura yemakambani emaindasitiri neyemigodhi, mapurojekiti emvura ekudzivirira moto, mapurojekiti ekudiridza mvura yemumapurazi, mapurojekiti ekurima nekurima girini, mapurojekiti emvura yemumvura yemugungwa, nezvimwewo.

2.PP-R pombi yemvura

Pombi yePP-R inonziwo pombi yepolypropylene yemhando nhatu, iyo inogadzirwa nepolypropylene yakasanganiswa isina kurongeka, inoburitswa mupombi, uye inopinzwa muzvigadziko zvepombi. Imhando itsva yepombi yepurasitiki yakagadzirwa uye yakashandiswa muEurope mukutanga kwema1990. Mukupera kwema1980, PP-R yakashandisa maitiro ekugadzira pombi yegesi kuti iite polymerize nenzira isina kurongeka uye yakafanana inenge 5% yePE mucheni yePP (random copolymerization) uye yakava chizvarwa chitsva chezvinhu zvepaipi. Ine simba rakanaka rekudzivirira uye inoshanda kwenguva refu.

Zvakanakira zvepaipi yePPR: mutengo uri pakati nepakati, kushanda kwakasimba, kuchengetedza kupisa nekupisa, kuramba ngura, madziro emukati akatsetseka asina kukweva, sisitimu yemapaipi yakachengeteka uye yakavimbika, haipindi mvura, uye hupenyu hwebasa hunosvika makore makumi mashanu. Inozivikanwa sekuti never scale, never rust, never leak, green advanced water supply material.

Zvakashata zvePPR pombi: zvinodiwa pakuvaka tekinoroji yepamusoro, maturusi akakosha uye nyanzvi dzinodiwa pakuvaka kuti ive nechokwadi chekuti sisitimu yakachengeteka.

Minda yekushandisa pombi yePPR:
1. Masisitimu emvura inopisa neinotonhora ezvivakwa, kusanganisira masisitimu ekupisa epakati;
2. Masisitimu ekudziisa muzvivakwa, kusanganisira pasi, siding uye masisitimu ekudziyisa ane radiant;
3. Sisitimu yemvura yekunwa yakachena;
4.Sisitimu yemhepo inotonhodza yepakati (centralized);
5. Masisitimu emapaipi eindasitiri akadai sekutakura kana kuburitsa michina yemakemikari.

3. Pombi yemvura inosanganiswa neAluminum-plastic

Pombi yesimbi yakagadzirwa nearuminiyamu nepurasitiki ndiyo pombi yekutanga yemvura yakatsiva pombi yesimbi yakakandwa. Muumbirwo wayo wekutanga unofanira kunge uri zvidimbu zvishanu, kureva purasitiki, chinhu chinonamira chinonyunguduka, chinhu chinonamira chinonyunguduka, chinhu chinonamira chinonyunguduka, uye chinhu chinonamira chinonyunguduka kubva mukati kusvika kunze.

Pombi yesimbi yakagadzirwa nearuminiyamu-purasitiki ine simba rakanaka rekudzivirira kupisa, uye madziro emukati nekunze haadi kuomeswa nengura. Nekuti madziro emukati akatsetseka, kuramba kwemvura kudiki; uye nekuti inogona kukotama chero painoda, zviri nyore kuisa nekuvaka.

Kune mhando nhatu huru dzemapaipi emvura ealuminium-plastic ari pamusika:
1, PE／AL／PE
(Polyethylene/Aluminium/Polyethylene)；
2, PE／AL／PEX
(Polyethylene/Aruminiyamu/Polyethylene Yakasanganiswa)；
3, PEX／AL／PEX
(Polyethylene/Aluminium/Polyethylene ine malinked akasanganiswa）.

Chekutanga ndechekuti zvikamu zvemukati nezvekunze ipolyethylene, chechipiri ndechekuti chikamu chemukati ipolyethylene yakabatana, chikamu chekunze ipolyethylene, uye chechitatu ndechekuti zvikamu zvemukati nezvekunze ipolyethylene yakabatana, uye chikamu chepakati ialuminium. Rudzi rwekutanga runowanzo shandiswa mumapombi emvura inotonhora, uye maviri ekupedzisira anowanzo shandiswa mumapombi emvura inopisa.

4. Pombi yemhangura

Inozivikanwawo sechubhu yemhangura. Rudzi rwepombi yesimbi isina ferrous, inova pombi yakadzvanywa uye yakadhonzwa isina musono.

Zvakanakira: Pombi yemhangura yakaoma, haisi nyore kuonda, uye inodzivirira kupisa kwakanyanya uye kumanikidzwa kwakanyanya. Ndiyo pombi yemvura yakanakisisa.

Zvakashata: mutengo wakakwira.

5. Mapaipi asina ngura akareruka

Chidimbu chesimbi isina ngura kana ndiro yesimbi isina ngura ine ukobvu hwemadziro hwe0.6 ~ 2.0mm, mapaipi akagadzirwa nemaitiro ekubatanidza fusion akadai se otomatiki argon arc welding.

Pombi yemvura yesimbi isina ngura yemumba ine madziro matete imhando itsva yepombi yakabuda mukupera kwema1990. Nekuda kwekuchengetedzeka kwayo uye kuchena, simba rayo guru, kuramba ngura zvakanaka, kugara kwenguva refu, kusachengetedza, uye chitarisiko chakanaka, pombi yemvura yesimbi isina ngura iripo parizvino ine simba guru rekukura. , Yakashandiswa zvakanyanya mukuvaka mapaipi emvura uye emvura yekunwa zvakananga.

Pombi isina tsvina ine mabhenefiti anotevera: hunhu hwakanaka hwemuchina, kuramba kupfeka zvakanaka, kuchengetedzeka kwakanaka uye hutano, kuramba kupisa zvakanaka, kuchengetedza kupisa zvakanaka, madziro emukati akatsetseka uye kuramba mvura kudiki; chitarisiko chakanaka, chakachena uye chine mafashoni, chakavimbika 100% Kudzokorodza uye kushandisazve; kubatsira kuchengetedza zviwanikwa zvemvura; kushandiswa kwakasiyana-siyana; kugara kwenguva refu uye mutengo wakaderera.

6.Pombi yesimbi yakanyudzwa inopisa

Mapaipi esimbi akakamurwa kuita mapaipi anotonhora akavharirwa uye mapaipi anodziya akavharirwa, ekutanga akarambidzwa. Pombi inodziya yakavharirwa ndeyekuita kuti simbi yakanyungudutswa iite seyakanyungudutswa nesimbi kuti igadzire alloy layer, kuitira kuti matrix ne coating zvisanganiswe. Hot-dip galvanizing ndeyekutanga yabvisa iron oxide pamusoro pepombi yesimbi, mushure mekuibvisa, inocheneswa neammonium chloride kana zinc chloride aqueous solution kana mixed aqueous solution yeammonium chloride ne zinc chloride, yozotumirwa ku hot dip coating tank.
