Tau PVC-U Cov Kua Nplaum Tsuas Lo Rau Cov Kav Dej PVC?

Tau PVC-U kua nplaum tsuas lo rau PVC kav?

Kev tsim kho ntawm PVC qhov dej ntws yog qhov yuav tsum nruab, thiab muaj kua nplaum tshwj xeeb thaum lub sijhawm teeb tsa. Qee tus neeg siv khoom xav tias PVC-U kua nplaum tuaj yeem tsuas yog cov kav dej hauv PVC. Qhov tseeb, kua nplaum no tseem tuaj yeem lo rau PPR kav thiab PE kav dej. , PERT kav thiab lwm cov khoom siv yas yeeb nkab. Ntawm chav kawm, nyob rau hauv ib txwm kev tsim kho, PPR kav, PE kav dej, thiab PERT kav yuav tsum tau welded los ntawm kub yaj lossis electrofusion. Cov nplaum tsuas yog qee zaum siv nyob rau hauv cov txheej txheem ntau lawm. Piv txwv, PPR khov kho-lub xeev cov kav dej muaj li PPR txheej thiab txhuas txheej. Tsib-txheej txheej co-extruded yeeb nkab muaj li ntawm txheej nplaum.

Cia' s saib nws cov kev siv tom qab lub luag haujlwm ntawm PVC-U kua nplaum:

1. Siv cov ntawv txhuam xim txhuam rau ntxhib thiab ntxuav cov seem uas xav tau sib txuas;

2. Tom qab tusyees sib kis tau tus nplaum rau ntawm qhov ntu, tam sim ntawd ntxig thiab ruaj khov nws ib pliag. Tsis txhob txav ntawm qhov sib khi hauv 15 feeb, thiab kuaj ntsuas dej kom ntshav tsuas yog ua tau tom qab 24 teev;

3. Qhov kis tau zoo tshaj plaws ntawm daim ntawv cog lus yog: 0.2-0.4mm;

4. Qhib cov nplaim taws raug txwv tsis pub muaj teeb meem ntawm qhov chaw tsim kho, thiab yuav tsum tau saib xyuas qhov cua;
