"Waterproof": piv nrog thawv, Hollow Board Box yog dej noo-tiv taus hauv cov khoom siv txias, thiab tam sim no yog siv cov dej txias
"Turnover": Vim tias nws cov yam ntxwv, nws cov khoom muaj peev xwm tiv thaiv, yog li nws tau hloov ua ib qho chaw thiab cov qauv siv hluav taws xob
Tom qab Hollow Board cov kab ntau lawm, nws tuaj yeem muab cov khoom siv rov qab los, thiab tom qab ntawd yog qhov ua kom muaj kuab paug tshiab, nws tuaj yeem ua tau, thiab tom qab ntawd yog cov pa phem tshiab
Hollow Board Cov Kab Ntau Lawm yog cov khoom siv los tsim PP hollow laug cam hollow {} Nws cov khoom siv tseem ceeb yog: (Cheebtsam ib nrab)
Cov ntaub ntawv Extruder: Siv cov ntaub ntawv nyoos raw thiab thawb cov ntaub ntawv tso tawm sib txawv raws li qhov loj me thiab nrawm ntawm cov ntsia hlau muaj kev txuag tau yooj yim dua yas ua haujlwm
Peb cov txiaj ntsig: Kev siv hluav taws xob siab .} piv nrog cov phooj ywg, lub cev muaj zog} Cov qauv sib txawv thiab nrawm.
