Cov thawv yas yog ib qho khoom siv ntim khoom siv hauv ntau yam. Lawv zoo heev durability, lightness, thiab waterproofness yog vim lawv tshwj xeeb raw khoom. Hauv qab no, peb yuav ua tib zoo saib cov ntaub ntawv tseem ceeb thiab lawv cov khoom rau cov thawv yas.
1. Polypropylene (PP)
Polypropylene yog ib qho ntawm cov khoom siv tseem ceeb rau cov thawv yas. Nws zoo heev tiv thaiv tshav kub, tshuaj tiv thaiv, thiab hluav taws xob rwb thaiv tsev cov khoom ua rau cov thawv yas kom muaj kev ua tau zoo hauv cov cheeb tsam hnyav xws li kub thiab av noo. Tsis tas li ntawd, polypropylene muaj zog thiab rigidity, ua rau cov thawv yas tsis tshua muaj deform thaum thauj khoom.
2. Polyethylene (PE)
Polyethylene kuj yog cov khoom siv raw rau cov thawv yas. Nws zoo heev yooj yooj yim, cuam tshuam tsis kam, thiab txias tsis kam ua rau cov thawv yas ua los ntawm polyethylene kom muaj zog toughness thiab cuam tshuam txawm nyob rau hauv qis - qhov kub thiab txias ib puag ncig. Polyethylene kuj muaj cov khoom siv dej tsis zoo, tiv thaiv cov ntsiab lus los ntawm ya raws.
3. Lwm yam additives
Ntxiv nrog rau polypropylene thiab polyethylene, cov thawv yas feem ntau ntxiv nrog cov khoom siv xws li plasticizers, stabilizers, thiab pigments. Cov additives no tuaj yeem txhim kho kev ua haujlwm ntawm cov yas crates, nce lawv lub neej, thiab muab ntau yam xim xaiv.
Cov ntsiab lus:
Plastic crates feem ntau yog tsim los ntawm polymers xws li polypropylene thiab polyethylene, nrog rau ntau yam additives. Cov khoom ntawm cov ntaub ntawv no pab txhawb rau lawv cov kev ua tau zoo, ua rau lawv tseem ceeb hauv kev xa khoom, chaw khaws khoom, thiab lwm yam haujlwm. Kev nkag siab txog cov khoom siv raw thiab cov khoom ntawm cov yas yas tuaj yeem pab peb xaiv thiab siv cov khoom ntim yooj yim no.
