Tus nqi ntawm cov pa oxygen iav fiber raj, yuav ua li cas?

Koj yuav tsum paub dab tsi thaum xaiv epoxy fiberglass yeeb nkab? Cia peb saib nws.

Tus nqi ntawm oxygen iav fiber ntau lub raj, qhov zoo sib txawv, tus nqi kuj txawv

1. Kov: Txawm hais tias qhov kev ntxhib los mos yog qhov me me thiab cov khoom sib xws zoo ib yam. Qhov zoo ntawm lub raj tsis daws qhov teeb meem. Yog tias koj kov nws, cov khoom ntxhib zoo li yuav sib xyaw nrog lwm cov impurities.
