Puas muaj kev nyab xeeb rau noj nrog cov ntawv pov tseg?
Cov ntaub ntawv pov tseg yog ua raws li daim ntawv, thiab qhov saum npoo yog npog nrog cov khoom siv paraffin, polyethylene txheej, thiab lwm yam. Nws yog siv rau kev ntim khoom noj lossis cov thawv rau cov dej kub thiab txias thiab cov khoom noj txias thiab kub. Daim ntawv tableware tuaj yeem muab faib ua cov duab los qhia cov ntawv tableware, Pulp molding paper tableware, coated paper tableware.
Cov ntawv tais diav pov tseg tau siv dav, thiab lub xeev yeej ib txwm txuas qhov tseem ceeb rau qhov zoo thiab kev nyab xeeb ntawm cov khoom zoo li no thiab tau suav nrog cov khoom zoo li no hauv cov khoom lag luam uas tau muab los ntawm cov ntawv tso cai tsim khoom. Rau qhov zoo thiab kev nyab xeeb ntawm cov ntaub ntawv pov tseg, peb feem ntau tsom mus rau peb yam: kev nyab xeeb ntawm lub cev, kev nyab xeeb huv, thiab kev nyab xeeb microbial, uas tau sau tseg raws li hauv qab no:
Lub cev zoo kev nyab xeeb yuav tsum tau:
Cov ntawv tais diav feem ntau yog ua los ntawm cov ntawv txiav ua ntej, tom qab ntawd khoov thiab sib koom, thiab thaum kawg thermoforming. Vim qhov zoo permeability ntawm daim ntawv cov ntaub ntawv nws tus kheej, zus tau tej cov tableware muaj nruj heev yuav tsum tau rau raw cov ntaub ntawv thiab cov txheej txheem. Kev tswj tsis raug yuav ua rau muaj teeb meem xws li lub cev qhuav dej ntawm cov tais diav lossis cov khoom noj los ntawm cov seams.
Txhawm rau ntsuas qhov kev nyab xeeb ntawm lub cev ntawm daim ntawv tais, lub teb chaws cov qauv tau tsim cov ntsuas xws li cov dej xau thiab kev ua haujlwm siab los ntsuas kev ua haujlwm ntawm cov ntawv tais diav. Txoj kev sim tshwj xeeb rau kev tiv thaiv dej yog ntxiv (90 ± 5) ℃ dej kub lossis roj-dej sib tov rau cov ntawv pov tseg cov tais diav kom simulate cov khoom noj tiag tiag.
Qhov siab ntawm kev ntxiv cov kua yuav tsum yog li 6 hli hauv qab ntawm ntug ntawm lub qhov ncauj ntawm lub rooj noj mov, thiab tom qab ntawd muab cov tais diav rau ntawm lub khob qhuav los yog lub phaj tiaj tus, thiab cia nws sawv ntsug li 30 feeb los saib seb puas muaj cov dej ntws los yog cov duab thaij duab ntawm lub qhov rooj. iav (flat) phaj. Tsim nyog.
Cov ntaub ntawv pov tseg pov tseg yuav tsum muaj qee qhov nyuaj thaum tuav cov zaub mov kom nws tsis deform thiab tawg thaum siv. Txhawm rau ntsuas lub peev xwm ntawm cov ntawv noj su lub thawv kom tiv thaiv sab nraud quab yuam, tus qauv tau tsim qhov ntsuas ntawm lub zog compressive, thiab qhov kawg crushed quab yuam tus nqi ntawm cov khoom yog kuaj los ntawm kev tsis tu ncua ua rau lub siab saum toj thiab hauv qab cov qauv. Qhov kev sim no tuaj yeem cuam tshuam zoo rau cov khoom siv kho tshuab ntawm cov khoom.
Sanitary Quality thiab Safety Requirements:
Cov txheej txheem tshiab hauv tebchaws yuav tsum tau siv cov ntaub ntawv pov tseg los ntsuas tag nrho cov kev tsiv teb tsaws, cov hlau hnyav (xws li cov hlau lead), poov tshuaj permanganate noj, thiab lwm yam kev ntsuas lub cev thiab tshuaj, thiab tseem yuav tsum tau tswj cov tshuaj fluorescent, hnyav hlau lead, cov ntsiab lus arsenic.
Cov khoom kuaj no tau sau ua ke hu ua kev noj qab haus huv thiab kev nyab xeeb. Lub hom phiaj ntawm qhov kev sim no yog simulate seb cov tais diav uas siv tau puas raug rau ntau yam dej haus thiab zaub mov ntawm qhov kub thiab txias thiab sij hawm sib txawv thiab seb cov khoom puas tsuaj puas yuav raug xa mus rau hauv cov zaub mov kom muaj kev phom sij rau tib neeg kev noj qab haus huv.
Txhawm rau kom muaj kev nyiam huv thiab kev nyab xeeb ntawm cov ntaub ntawv pov tseg, lub xeev tau tshaj tawm cov qauv tsim nyog. Ntxiv nrog rau cov qauv ntsuas, nws kuj tseem qhia txog kev nyiam huv thiab kev nyab xeeb ntawm cov tuam txhab tsim khoom lag luam, cov kev cai rau cov khoom siv raw uas tau tso cai siv rau hauv kev tsim khoom, thiab siv cov ntawv tso cai rau cov tuam txhab tsim khoom. Txhawm rau kom ntseeg tau tias cov khoom zoo li no yuav tsis ua rau tib neeg noj qab haus huv.
Tsis tas li ntawd, cov tuam txhab pov tseg cov ntawv tais diav kuj yuav tsum tau kos cov khoom ntim nrog cov lus tshaj tawm ntawm kev ua raws li cov cai thiab cov qauv, lub npe, chaw nyob thiab cov ntaub ntawv tiv tauj ntawm cov chaw tsim khoom thiab (lossis) tus neeg xa khoom, hnub tsim khoom thiab lub neej txee, thiab lwm yam. thiab teeb meem kev nyab xeeb tuaj yeem taug qab sai sai rau qhov chaw.
Microbiological kev nyab xeeb yuav tsum muaj:
Cov kab mob microbes ntau dhau yog qhov txaus ntshai rau cov ntaub ntawv pov tseg. Thaum lub sij hawm tsim thiab ua cov khoom, yog tias cov tshuaj tua kab mob ntawm qhov chaw ua haujlwm tsis zoo, ntau yam kab mob pathogenic thiab pwm tuaj yeem cuam tshuam nrog cov khoom thiab ua rau muaj kuab paug.
Kev tuav tsis raug thaum lub sijhawm thauj khoom kuj tseem tuaj yeem ua rau cov kab mob microbial ntau dhau vim yog ntim khoom puas. Yog tias cov khoom raug muab tso rau hauv qhov chaw ntub dej, kub, thiab tsis muaj qhov chaw cia khoom, tshwj xeeb tshaj yog nyob rau lub caij ntuj nag, qhov kub thiab av noo tsim nyog yuav ua rau cov kab mob sib kis, yog li cov chaw tsim khoom ntawm cov ntaub ntawv pov tseg yuav tsum muaj kev tswj xyuas nruj thaum lub sijhawm tsim khoom, suav nrog ruaj khov ntawm cov khoom. , ntau lawm thiab cia nyob rau hauv ib puag ncig uas ua tau raws li cov kev cai ntawm kev tu cev.
Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau kev tswj hwm ib puag ncig hauv cov txheej txheem siv los tiv thaiv cov khoom kom tsis txhob muaj kab mob thiab ua rau muaj kev phom sij rau kev noj qab haus huv.
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm" Internet + catering kev pab cuam", kev siv cov tais diav pov tseg nyob rau hauv lub tshav pob ntawm takeaway kuj tseem nce ntxiv, uas tau ua rau muaj kev txhawj xeeb txog. ib puag ncig muaj kuab paug.
Thaum Lub Ib Hlis 19, 2020, National Development thiab Reform Commission thiab Ministry of Ecology thiab Ib puag ncig tau tshaj tawm" Cov Kev Pom Zoo Ntxiv Ntxiv Kev Txhim Kho Kev Tswj Cov Ntawv Pov Hwm", yuav tsum tau tsim thiab muag cov ntawv ua npuas ncauj pov tseg. tableware los ntawm qhov kawg ntawm 2020, nyob rau hauv cov cheeb tsam tsim thiab scenic chaw nyob rau hauv cov nroog saum toj no prefecture-theem Kev siv cov khoom uas tsis yog-degradable pov tseg yas tableware yog txwv tsis pub rau noj hmo nyob rau hauv cov chaw scenic; Thaum kawg ntawm xyoo 2022, kev siv cov tais diav uas tsis yog-degradable pov tseg yog txwv tsis pub noj hmo hauv cov chaw ua haujlwm thiab cov chaw zoo nkauj hauv nroog; Kev siv cov khoom siv ntawm cov khoom siv uas tsis yog-degradable pov tseg yog txo los ntawm 30%.
Lub" Kev xav" tawm tswv yim los txhawb kev siv cov khoom siv bio-based xws li straw-coated tableware thiab cov hnab ntawv degradable uas ua tau raws li kev ua tau zoo thiab kev nyab xeeb ntawm cov khoom noj hauv kev xa zaub mov.
Txoj cai no muab lub sijhawm zoo dua rau kev tiv thaiv ib puag ncig kev txhim kho ntawm cov ntaub ntawv pov tseg pov tseg. Nyob rau hauv xyoo tas los no, cov khoom tshiab xws li bagasse tableware thiab pulp molded tableware kuj tau tshwm sim. Qhov tshwm sim ntawm no cellulose tableware yuav muab kev txhawb zog rau kev daws teeb meem ib puag ncig.
