Vim hais tias cov phab ntsa tuab ntawm cov txiv hmab txiv ntoo crates tsis yog ib txwm zoo ib yam, thiab kom txo lub sij hawm txias rau kev ua tau zoo, kev tsim cov dej txias hauv cov pwm yog qhov tseem ceeb.
Lub qhov dej - tsim cov dej txias channel layout ua kom cov khoom txias sib xws, txo cov kev ntxhov siab sab hauv, thiab tiv thaiv deformation.
Cov khoom siv yas feem ntau siv los ua cov txiv hmab txiv ntoo crates yog polypropylene thiab siab -density polyethylene (HDPE). Ob leeg cov ntaub ntawv muaj zoo toughness, cuam tshuam tsis kam, thiab tshuaj corrosion kuj, ua rau lawv haum rau siv sab nraum zoov.
Polypropylene muaj me ntsis zoo rigidity thiab siab kub kuj; HDPE muaj qhov ua tau zoo dua - qhov kub thiab txias tsis kam. Kev xaiv ntawm cov khoom siv raw yog nyob ntawm yam xws li kev siv ib puag ncig thiab tus nqi.
Qee zaum, qee qhov kev faib ua feem ntawm cov khoom siv rov ua dua yog siv los txo cov nqi thaum tswj kev ua haujlwm, ua raws li cov hauv paus ntsiab lus ntawm kev lag luam ncig.
