Kev tsim cov txheej txheem ntawm mulch film muaj ob peb kauj ruam:
- Blending: Cov ntaub ntawv raw, xws li polyethylene resins, colorants, stabilizers, thiab additives, yog blended nyob rau hauv meej proportions kom ua tiav cov yam ntxwv xav tau.
- Extrusion: Cov ntaub ntawv sib xyaw yog pub rau hauv extruder, uas lawv tau yaj thiab tsim rau hauv daim ntawv txuas ntxiv. Lub thickness thiab dav ntawm zaj duab xis yog tswj thaum extrusion.
- Cua Txias: Cov zaj duab xis molten yog txias siv cov chilled rollers los yog dej-txias troughs kom khov nws.
- Winding: Tom qab txias, zaj duab xis raug mob rau hauv yob ntawm qhov ntev thiab dav, npaj rau kev faib thiab siv.
