Kev siv PVA fiber ntau hauv pob zeb

Abstract:

Polyvinyl cawv (PVA) fibers tau tshwm sim los ua ib qho kev cog lus ntxiv hauv kev siv tshuab ua vaj tse, pab txhim kho ntau yam khoom siv thiab ua haujlwm ntev. Qhov kev tshuaj xyuas zoo no tshuaj xyuas qhov cuam tshuam ntawm kev sib koom ua ke PVA fibers rau hauv cov khoom sib xyaw ua ke, sib tham txog lawv cov khoom, kev tsim khoom, thiab ntau yam kev siv hauv kev tsim kho. Kev sib tham suav nrog cov teebmeem ntawm PVA fibers ntawm cov khoom tshiab thiab tawv tawv ntawm cov pob zeb, lawv lub luag haujlwm hauv kev tiv thaiv cov kab nrib pleb, thiab cov txiaj ntsig zoo ib puag ncig cuam tshuam nrog lawv siv. Tsis tas li ntawd, cov kev cov nyom thiab cov kev cia siab yav tom ntej tau raug qhia kom coj mus rau kev tshawb fawb thiab kev loj hlob ntxiv hauv daim teb no.
