Hauv cov txheej txheem tsim cov hnab ntim cov hnab yas, cov khoom sib xyaw yog qhov txuas tseem ceeb uas cuam tshuam ncaj qha rau qhov zoo thiab kev ua haujlwm ntawm cov khoom kawg. Nov yog qee qhov kev ceev faj tseem ceeb:
1. Raw khoom xaiv
Kev Tswjhwm Zoo: Xyuas kom meej tias cov khoom siv yas siv (xws li polyethylene, polypropylene, thiab lwm yam) ua tau raws li cov qauv kev lag luam thiab yog los ntawm cov khoom siv txhim khu kev qha.
Cov khoom sib piv: Raws li cov khoom siv sib txawv, tsim nyog xaiv thiab sib piv cov ntaub ntawv raw los xyuas kom muaj qhov sib npaug ntawm kev ua haujlwm thiab tus nqi.
2. Kev npaj khoom siv
Cov khoom siv tu: Ua ntej sib xyaw cov ntaub ntawv, xyuas kom meej tias cov khoom sib xyaw yog huv si thiab tsis muaj impurities kom tsis txhob muaj kev cuam tshuam ntawm kev sib xyaw ntawm cov khoom sib txawv.
Cov cuab yeej debugging: Tshawb xyuas qhov kev khiav hauj lwm ntawm lub tov khoom kom paub meej tias nws ua haujlwm ib txwm kom tsis txhob cuam tshuam rau kev sib xyaw.
3. Kev tswj qhov kub thiab txias
Qhov ntsuas kub tsim nyog: Thaum lub sij hawm sib tov, kev tswj xyuas qhov ntsuas kub kom haum yuav pab kom cov khoom sib xyaw zoo sib xws thiab tiv thaiv kom tsis txhob degradation ntawm cov khoom siv vim qhov kub thiab txias heev.
Kev saib xyuas lub sijhawm tiag tiag: Siv cov ntsuas kub ntsuas los saib xyuas qhov kub hloov pauv thaum lub sijhawm sib xyaw ua ke hauv lub sijhawm.
4. Lub sijhawm tswj
Lub sijhawm sib xyaw: Tswj lub sijhawm sib xyaw. Ntev dhau lawm yuav ua rau cov khoom degradation lossis hloov pauv ntawm lub cev, thaum luv luv yuav ua rau cov khoom sib xyaw tsis sib xws.
Kev tshuaj xyuas tsis tu ncua: Txheeb xyuas qhov sib xyaw ua haujlwm tsis tu ncua thaum lub sijhawm sib xyaw kom paub meej tias qhov zoo sib xws tau ua tiav.
5. Kev siv cov tshuaj ntxiv
Kev xaiv tsim nyog: Thaum lub sij hawm sib tov, yog tias cov khoom siv ntxiv (xws li antioxidants, plasticizers, thiab lwm yam) yuav tsum tau muab ntxiv, hom thiab qhov tsim nyog yuav tsum tau xaiv.
Uniform faib: Xyuas kom meej tias cov additives yog tag nrho tov nrog cov khoom siv los ua kom lawv cov txiaj ntsig zoo.
6. Kev ntsuas kev nyab xeeb
Cov cuab yeej tiv thaiv: Cov neeg ua haujlwm yuav tsum hnav cov cuab yeej tiv thaiv tsim nyog, xws li hnab looj tes, qhov ncauj qhov ntswg, thiab lwm yam kom muaj kev nyab xeeb.
Qhov cua zoo: xyuas kom meej tias thaj chaw sib xyaw yog qhov cua zoo kom tsis txhob muaj cov pa phem.
7. Cov ntaub ntawv thiab traceability
Cov ntaub ntawv ntau lawm: Sau cov ntaub ntawv raw batch naj npawb, piv txwv, sijhawm thiab lwm yam ntaub ntawv ntawm txhua qhov sib xyaw kom meej rau kev taug qab thiab kev tswj kom zoo.
Kev tshawb xyuas tsis tu ncua: Kev tshuaj xyuas tsis tu ncua thiab tshuaj xyuas cov txheej txheem sib xyaw kom paub thiab daws teeb meem raws sijhawm.
Cov txheej txheem sib xyaw ntawm cov hnab ntim cov hnab yas yuav tsum muaj kev tswj xyuas zoo thiab kev tswj xyuas kom zoo thiab sib xws ntawm cov khoom. Los ntawm kev ua tib zoo xaiv cov khoom siv raw, cov khoom siv raws li txoj cai, ntsuas kub thiab sijhawm, kev ntsuas kev nyab xeeb thiab lwm yam, kev ua haujlwm ntawm kev sib xyaw thiab kev ua haujlwm ntawm cov khoom tuaj yeem txhim kho tau zoo.
