Dab tsi yog peb feem ntau siv cov ntaub ntawv yas

Nco ntsoov hais peb, nws yuav tsum yog: PPR, PVC, PE

1. Cov kav dej feem ntau yog: PPR (polypinylene), pyyethylene), PE (kub-density polyethylene) ethylene), lwm yam.

Thib ob, qhov loj ntawm cov kav dej yas yog feem ntau qhia tawm hauv cov nqe lus ntawm txoj kab uas hla. Xws li PPR Tube: DE63

3. Qhov kev pabcuam lub neej ntawmMf pob valve X9011yog txiav txim raws li GB / T18252-2000 "yas piping system - kev txiav txim siab ntawm lub zog hydrostatic kav los ntawm kev rho tawm cov kav dej". Nov yog ib txoj kev ntawm lub ntsiab lus thiab kwv yees lub zog muaj zog ntev ntawm cov ntaub ntawv thermopictic lossis cov lus los ntawm hydrostatic lub zog ntsuas ntawm cov kav dej. * Feem ntau ntawm cov saum toj no txoj kev los laij, hauv qab qhov kub ntawm 20 ℃, cov yeeb nkab yas feem ntau muaj lub neej ntawm 50 xyoo.

Thib plaub, cov khoom siv hluav taws xob rau cov kav dej yas yog qhov txhaj tshuaj molding tshuab, uas yog pwm rau cov kav dej los ntawm kev txhaj tshuaj molding tshuab.

5. Feem ntau muaj ob txoj hauv kev los txuas yas kav dej: 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 (Txhim Kho Siab Loj Polyethylene): GB / T19472.2-2004

Yas kav hlau tsuas yog suav nrog PPR (polypropylene), pogyhlene), PE (kev kub siab (HDPE) Polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE) thiab lwm cov polymers.

Yas yeeb yog lub sijhawm dav dav rau cov kav dej ua los ntawm cov ntaub ntawv yas. Cov kav dej yas muaj cov yam ntxwv ntawm lub teeb yuag, kev nyab xeeb, kev nyab xeeb ntawm cov neeg nyob ib zej zog engineering zej zog. Hauv 10 lub xyoo dhau los, tsav los ntawm kuv lub teb chaws macroeconomic kev loj hlob, kuv lub teb chaws cov kav dej yas tau ntsib cov khoom siv nrawm ntawm cov khoom siv hauv tsev. Xyoo 2010, lub teb chaws tso zis ntawm cov kav dej yas tau ntau dua 8 lab tons, uas Guangdong, Zhejiang thiab Shandong suav tau rau 42% ntawm cov zis. Yas Pipes muaj ntau qhov zoo dua cov kav hlau ib txwm muaj thiab cov kav pob zeb ua paj nruag hauv ntau thaj teb, yog li lawv tau siv dav hauv ntau thaj chaw.
