Kuaj cov khoom rau PVC kav

Rau cov kav dej PVC

Raws li tus qauv ntawm tus txheeb ze (ISO4435), Cov tshuaj polyvinyl chloride (PVC-U) thiab cov fittings

Rau cov faus dej thiab cov kav dej xau   yuav tsum tau xeem txoj kev kuaj nram no:

EX Hoobkas kuaj:

1. Lub qhov cub rov qab (Lub qhov cub txias)

2. ntog huab hwm coj kev sib tw (Kev sib tw loj feem huab tshuab kuaj ntsuas kub tsawg)

3. Methylene chloride soak test (Methylene chloride soak tester)

Cov ntawv xeem:

1. Kev sib tw khiav ceev (lub tshuab ntsuas dav dav)

2. Ceev (Qhov Ceev Ceev)

3. Vicat softening point test ((HDT & vicat softening point testing machine)

4. Kev sib tw qhov kev sib tw kev sib tw (Hydrostatic pressure testing machine)

Rau PVC siab kav

Raws li tus txheej txheem ntawm

ISO4422 : Cov kav dej thiab fittings uas ua los ntawm cov khoom siv tsis siv tau (yas chloride) (PVC-U) rau dej

UPVC yeeb nkab rau dej yuav tsum tau kuaj cov nram qab no

Ex Factory cov khoom kuaj:

1. Longitudinal reversion (cua qhov cub)

2. Kev Ntsuam Ntsuam Phem Feem Xeeb (Cov kav dej yas ntog hnyav kuaj tshuab)

3. Ntsuas qhov kub thiab txias kom tsawg (Rau khov tus qauv, ces coj cov kev kuaj ntawm huab cua)

4. Hydrostatic kev xeem siab (Yas kav hydrostatic siab tshuab)

Cov khoom kuaj sim :

5. Vicat softening temperature (Vicat & HDT softening ntsuas kub ntsuas)

6. Methylene chloride tsau (methylene chloride tsau tester)

7. Kev Ntsuam Ntsuam Phem Feem Xeeb (Cov kav dej yas ntog loj huab cua tshuab kuaj tshuab)

8. Kev ntsuam xyuas ceev (tensity tester)
