Cov khoom siv rau lub thawv ntawv

Cov thawv ntawv noj su yog cov thawv ntim khoom noj uas siv tau los ntawm cov ntawv ua cov substrate, nrog cov yam ntxwv ntawm tus nqi qis thiab siv tau yooj yim. Lawv tau muab faib ua peb pawg raws li cov khoom siv ua haujlwm: cardboard noj su lub thawv, pulp molded ntawv noj su lub thawv, thiab laminated ntawv noj su lub thawv. Ntawm lawv, laminated ntawv noj su lub thawv yog qhov ntau tshaj plaws, uas yog tsim los ntawm kev sib txuas cov ntawv sib cuag nrog cov ntaub ntawv polyethylene los yog polylactic acid (PLA) laminated txheej. Nws cov thev naus laus zis ntau lawm yuav tsum ua raws li lub teb chaws tus qauv ntawm "Paper Tableware", thiab kev tshuaj xyuas cov khoom yuav tsum ua raws li tus qauv GB / T 2828. Lub ntim yuav tsum tau sau nrog hnub tas sij hawm thiab lub txee lub neej yuav tsum tsis pub tshaj 1 xyoos.
Cov txheej txheem ntau lawm ntawm cov thawv ntawv noj su suav nrog cov txheej txheem xws li pulp ua, sib sau, molding thiab ziab, shaping thiab trimming. Pulp molding tshuab siv cov pwm hlau kom lub cev qhuav dej thiab tsim, thiab tseem muaj kev ua kom tsis muaj menyuam. Nyob rau hauv teb rau qhov teeb meem ntawm tsis txaus waterproof thiab roj resistant kev ua tau zoo, kev tshawb fawb thiab kev loj hlob tsom mus rau kev hloov kho ntawm cov nroj tsuag fiber ntau raws li cov ntaub ntawv thiab fluorine dawb roj resistant technology. Qhov nyuaj ntawm kev rov ua dua tshiab thiab pov tseg cov txheej txheej yas ntawm cov ntawv laminated cov thawv noj su tau ua rau muaj kev sib cav txog ib puag ncig. Txawm li cas los xij, lawv tuaj yeem muab pov tseg los ntawm kev rov ua dua tshiab, faus, lossis hlawv. Txoj haujlwm tsav hauv Shanghai los hloov cov thawv ntim khoom noj su nrog cov ntawv laminated tuaj yeem txo cov pov tseg yas los ntawm 75%. Kev lag luam xws li Hengxin Life thiab Zhongxin Co., Ltd. ua cov kev tshawb fawb thiab kev tsim cov khoom siv biodegradable, ntawm cov PLA coated ntawv noj su thawv tuaj yeem decomposed nyob rau hauv ib lub sij hawm luv luv los ntawm biodegradation.
