Ndeupi musiyano uripo pakati pePU nesimbi yesimbi yakagadzirwa nesimende?

Mapaipi esimbi akagadzirwa nesimbiMapedhi epurasitiki akafukidzwa nePU nesimbi yesimbi inonzi simende ndiwo marudzi maviri akajairika emapedhi epurasitiki, akasiyana zvakanyanya muzvinhu zvawo zvepurasitiki, maitiro azvo, uye mashandisirwo azvo. Ose ane chinangwa chikuru: kuchengetedza pombi kubva mukuora kubva kune zvinotakurwa uye kuona kuti mvura/mvura inoyerera zvakanaka. Zvinotevera zvinotsanangura musiyano uripo pakati pemapaipi maviri aya esimbi akafukidzwa nesimbi.

Kushanda Kukuru:

• Simende yakafukidzwa nesimbi ine ductile: Inonyanya kushandiswa pakugadzira mvura isina kubikwa, mvura yekunwa, mapaipi etsvina ane simba shoma;
• PU yakafukidzwa neductile simbi pombi: Tsvina inoparadza, kubvisa munyu mumvura yegungwa, mvura inoraswa mumaindasitiri, kutakurwa kwemvura yakawanda;

Nzira yekudzivirira ngura:

• Ductile iron pombi simende coating: Firimu repamusoro re alkaline passivation uye physical isolation;
• Ductile simbi pombi polyurethane coating: Kuvhara kwakasimba uye kusashanda kwemakemikari, hapana kupinda mukati;

Zvimiro zvePamusoro:

• Simende yakafukidzwa nesimbi ine ductile: Kukosha kwehuremu K≈0.03mm, zviri nyore kuyera;
• PU yakafukidzwa neductile simbi pombi: Nzvimbo yakatsetseka, roughness coefficient K <0.01mm, hapana scaling, hydraulic loss diki;

Kuramba Kukuvara/Kukanganisa:

• Pombi yesimbi yakaputirwa nesimende:Kazhinji, zvinogezwa nyore nyore nezvidimbu zvakaoma;
• PU yakafukidzwa neductile simbi pombi：Yakakwirira zvakanyanya, inogona kutakura zvinhu zvine jecha netsvina;

Kuchinjika paTembiricha:

• Simende yakafukidzwa nesimbi ine ductile：0 – 80℃；
• Kuputira nekuisa jira rePolyurethane paDuctile Iron Pipe: -40 – 120℃；

Rudzi rweUtsanana:

• Simende yakafukidzwa nesimbi ine ductile:Tevedzera mitemo yemvura yekunwa;
• PU yakafukidzwa neductile simbi pombi:Haina zvinonyungudutsa, haina VOC, ine chitupa cheNSF/WRAS, uye inogona kushandiswa pamvura yekunwa zvakananga;

Hupenyu hwebasa:

• Simende yakafukidzwa nesimbi ine ductile:makore ≥50;
• PU yakafukidzwa neductile simbi pombi:makore ≥100 uye nguva yakareba isina kugadziriswa;

Mutengo Wose:

• Simende yakafukidzwa nesimbi ine ductile:Mari shoma uye iri nyore kugadzira;
• PU yakafukidzwa neductile simbi pombi:Mutengo wakakwira asi mutengo wakaderera wehupenyu hwese;

Lining yesimende inodhura zvishoma uye inoshanduka-shanduka, yakakodzera kushandiswa kwemvura yemazuva ano; Lining yePU "haina kupindira kwemvura + inodzivirira kusakara zvakanyanya" ndiyo sarudzo yekutanga kune ngura yakawanda, kuyerera kwakanyanya uye kugara kwenguva refu.taura nesukuti uwane rumwe ruzivo rwekuti ungasarudza sei pombi yeDI yakakodzera.
