Taw qhia
"Wood Imitation" qauv ua npuas ncauj, yog ib hom tshiab ntawm cov khoom siv hluavtaws.Nws muaj cov neeg kho tshuab siab zog thiab hardness, yooj yim molding txheej txheem, siab ntau lawm efficiency thiab zoo heev tsos.
Cov yam ntxwv yog raws li nram no,
1. zoo heev repetition molding khoom.Nws tsis tsuas yog tuaj yeem pwm qee qhov loj me, tab sis kuj tuaj yeem pwm cov ntoo zoo li ntoo thiab lwm yam tsim, kov zoo.
2. zoo nkaus li thiab xav tias ze rau ntoo, uas tuaj yeem npaj, ntsia hlau, tho, thiab cov qauv kos duab lossis cov qauv tsim.
3. Pwm tuaj yeem yog txhuas lossis hlau, thiab silicon roj hmab, epoxy resin lossis lwm yam resins, uas yog tus nqi qis thiab kev ua haujlwm yooj yim.
4. txheej txheem yog yooj yim, ceev, high efficiency ntawm tsim nyog.
5. lub cev thiab cov khoom siv kho tshuab yog ib qho zoo tshaj plaws synthesis ntoo ua los ntawm ntau yam polymer.Lub cev muaj zog tuaj yeem tswj tau los ntawm kev kho cov qauv.
