Nco ntsoov hais peb, nws yuav tsum yog: PPR, PVC, PE
1. Feem ntau siv cov kav dej yas yog: PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (heat-resistant polyethylene), PE (polyethylene) \ HDPE (reinforced high-density polyethylene) ethylene), lwm.
Qhov thib ob, qhov loj ntawm cov kav dej yas yog feem ntau qhia nyob rau hauv cov nqe lus ntawm sab nraud txoj kab uas hla.Xws li PPR raj: De63
3. Kev pab lub neej ntawmMF POB VALVE X9011Kev txiav txim siab raws li GB / T18252-2000 "Plastic piping system - Kev txiav txim siab ntawm lub sij hawm ntev hydrostatic zog ntawm cov kav dej thermoplastic los ntawm kev ntxiv".Qhov no yog ib txoj hauv kev ntawm statistically extrapolating thiab kwv yees lub sij hawm ntev lub zog ntawm cov ntaub ntawv thermoplastic los yog cov khoom los ntawm cov txiaj ntsig ntawm hydrostatic zog kuaj cov kav dej.* Feem ntau ntawm cov saum toj no siv cov qauv no los xam, nyob rau hauv qhov kub thiab txias ntawm 20 ℃, cov yeeb nkab yas feem ntau muaj lub neej ntev ntawm 50 xyoo.
Plaub, cov khoom siv molding rau cov kav dej yas yog lub tshuab txhaj tshuaj molding, uas yog molded rau hauv cov kav dej los ntawm kev txhaj tshuaj molding tshuab.
5. Feem ntau muaj ob txoj hauv kev los txuas cov kav dej yas: kub yaj thiab kua nplaum.
6. Cov qauv rau cov kav dej yas feem ntau suav nrog:
1. PPR (polypropylene): GB/T18742.1, GB/T18742.2, GB/T18742.3
2. PVC (polyvinyl chloride): GB / T10002.1-2006, GB / T10002.2-2003
3. PE (polyethylene): GB15558, GB/T13663
4. HDPE (Enhanced High Density Polyethylene): GB/T19472.2-2004
Cov kav dej yas feem ntau muaj xws li PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (polyethylene tshav kub), PE (polyethylene), HDPE (hloov high-density polyethylene), thiab lwm yam. Cov ntaub ntawv siv yog polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE) thiab lwm yam polymers.
Cov yeeb nkab yas yog ib lo lus dav dav rau cov kav dej ua los ntawm cov khoom yas.Cov kav dej yas muaj cov yam ntxwv ntawm lub teeb yuag, kev nyab xeeb thiab kev nyab xeeb, me me dej ntws tsis kam, txuag hluav taws xob, txuag hluav taws xob, txhim kho kev nyob ib puag ncig, kev pab lub neej ntev, kev nyab xeeb thiab yooj yim, thiab lwm yam, thiab tau txais kev nyiam los ntawm cov kav dej engineering hauv zej zog.Hauv 10 xyoo dhau los, tau tsav los ntawm kuv lub teb chaws txoj kev loj hlob macroeconomic, kuv lub teb chaws cov kav dej yas tau ntsib kev loj hlob sai nyob rau hauv keeb kwm yav dhau los ntawm kev loj hlob zoo ntawm cov khoom siv hauv tsev.Nyob rau hauv 2010, lub teb chaws tso zis ntawm cov kav dej yas tau tshaj 8 lab tons, uas Guangdong, Zhejiang thiab Shandong suav txog 42% ntawm cov zis.Cov kav dej yas muaj ntau qhov zoo dua li cov kav hlau ib txwm siv thiab cov kav dej ua vaj tse hauv ntau qhov chaw, yog li lawv tau siv dav hauv ntau qhov chaw.
