Ob hom kev lag luam qhov chaw

Cov thawv ntim khoom muaj xws li: ntim ntim, ntim ntim ntim ntim / ntim ntim, thiab ntim ntim ntim. Txawm li cas los xij, nrog rau kev loj hlob ntawm cov txheej txheem tshuab moulding, muaj ntau thiab ntau lub tshuab moulding khoom rau cov khoom lag luam, thiab cov peev txheej ntawm daim ntawv thov kuj nce ntxiv. Tam sim no, ntim khoom suav txog li 80 feem pua ​​​​ntawm kev lag luam sib koom, nrog rau kev loj hlob txhua xyoo ntawm 4 feem pua; thaum cov khoom lag luam thiab cov qauv tsim muaj 20 feem pua ​​​​ntawm tag nrho, nrog rau kev loj hlob txhua xyoo ntawm 12 feem pua. Kev nce hauv cov ntim ntim yog vim qhov kev nthuav dav ntxiv ntawm daim ntawv thov ntau yam ntawm cov thawv yas twistable, thiab kev nce hauv kev noj cov khoom lag luam feem ntau yog los ntawm kev txhim kho cov txheej txheem tshiab, xws li ntau txheej parison extrusion, biaxial extrusion. , tsis-axial extrusion. Table 2 teev ib co ntawm cov tshuab molded cov khoom siv thiab lawv cov kev ua tau zoo.
