Yuav txiav txim qhov zoo ntawm PVC hose

1, Ntim:

1. Ntsuas phab ntsa thickness: saib seb puas tau teev cov phab ntsa thickness. Ntawm no, peb yuav tsum tau them sai sai rau tias qee cov kav dej raug tshem tawm cov kav dej, thiab cov phab ntsa tuab ntawm ob qhov kawg ua tau raws li qhov yuav tsum tau ua, tab sis cov phab ntsa nruab nrab yog nyias, uas tsis ua raws li kev siv. Nyob rau tib lub sijhawm, tus nqi raug txo los ntawm kev khiav tawm.

2. Qhov ntev: saib seb qhov ntev npaum li cas mus txog. Qee cov tuam ntxhab txo tus nqi los ntawm kev ua kom luv luv. Raws li GB / t 10002 1-2006 qhia tias qhov tsis zoo sib txawv tsis raug tso cai.

2, Saib:

1. Saib gloss: cov khoom uas zoo nto gloss thiab zoo oiliness yog zoo.

2. Saib cov xim: tus qauv PVC-U yeeb nkab yog lub teeb beige. Yog hais tias cov yeeb nkab yog daj ntseg, nws qhia tau hais tias cov hmoov calcium ntxiv ntxiv. Qee cov tuam ntxhab ntxiv cov khoom siv ntau dhau thiab cov khoom siv rov ua dua tshiab, thiab cov yeeb nkab yog xim dub thiab daj.

3, Nyhav:

Qhov hnyav: piv qhov hnyav ntawm ob lub kav dej nrog tib txoj kab uas hla, phab ntsa thickness thiab ntev. Cov hmoov calcium thiab impurities nrog hnyav hnyav yog ntxiv ntau dhau, thiab cov khoom tsis huv, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.

4, Caij nplooj zeeg:

Yog tias ua tau, koj tuaj yeem ua rau ntawm ntug ntawm cov yeeb nkab kom pom tias nws tuaj yeem tawg tau yooj yim. Nqa cov yeeb nkab PVC thiab poob rau hauv av. Yog tias cov yeeb nkab tawg yog "siab calcium nti", qee cov tuam ntxhab ntxiv cov hmoov calcium ntau dhau hauv cov yeeb nkab tsim kom txuag tau cov nqi thiab txhim kho cov txiaj ntsig. Cov yeeb nkab zoo li no pheej yig, tab sis nws qhov hardness tsawg dua, tsis yooj yim thiab tsis tsim nyog. Cov kav dej PVC tuaj yeem raug tsoo los ntawm kev ncaws lossis txawm tias dov nrog lub tsheb. Cov kav dej tsis zoo PVC tuaj yeem raug tsoo los ntawm kev ncaws.

5, Kev tshuaj xyuas:

1. Daim ntawv tshuaj ntsuam xyuas thiab kuaj: daim ntawv tshuaj ntsuam xyuas ntawm cov yeeb nkab thiab daim ntawv ntsuam xyuas ntawm nws qhov ntsuas kev huv yuav tsum tau txais, thiab cov khoom qub yuav tsum zoo zoo.

2. Kev ntsuas ntsuas (raws li GB / t10002.1-2006);

3. Vicat softening kub siab dua los yog sib npaug rau 80 degree;

4. Longitudinal retraction tus nqi Tsawg dua los yog sib npaug li 5 feem pua;

5. Tsis muaj kev hloov ntawm impregnated nto;

6. Kev ntsuas qhov hnyav poob qis (0 degree), TIR Tsawg dua lossis sib npaug li 5 feem pua ​​;

7. Kev ntsuas hydraulic tau ua tiav ntawm 20 degree, lub nplhaib kev ntxhov siab yog 36Mpa / 38Mpa, thiab tsis muaj pob txha thiab to tom qab 1 teev.
