1, Cov ntaub ntawv xav tau rau kev tsim cov qe tais
1. Cov khoom siv tseem ceeb
-Cov ntaub ntawv pov tseg: suav txog 70% -90% (xa mus rau "Kev Lag Luam Tus Qauv rau Ntim Cov Khoom Siv Pulp Moulding"), feem ntau yog siv cov khoom siv rov ua dua tshiab xws li cov ntawv xov xwm pov tseg thiab cov thawv ntawv, uas yuav tsum tau kho ua ntej xws li pulping, deintercalation, thiab tshuaj ntsuam.
-Adhesive: feem ntau siv cov hmoov txhuv nplej siab los yog PVA nplaum (ib puag ncig tus phooj ywg), nrog rau qhov sib ntxiv ntawm 5% -10% kom ntseeg tau tias muaj zog molding.
-Tus neeg saib xyuas dej tsis zoo: xws li cov tshuaj pleev tshuaj paraffin (1% -3%), siv los txhim kho cov dej tsis zoo ntawm lub tais.
2. Cov khoom siv pabcuam
-Dyes: Cov zaub mov qib pigments (xws li hlau oxide liab) siv los qhia qhov txawv ntawm cov khoom sib txawv.
-Txhim kho fiber ntau: Qee qhov siab- cov khoom kawg ntxiv xyoob fiber ntau los yog qab zib bagasse los txhim kho lub zog compressive (tuaj yeem tiv taus 5-8kg / pallet).
2, Kev piav qhia ntxaws ntawm txoj kev tsim khoom
1. Raw khoom npaj theem
- Tom qab muab cov ntawv pov tseg, sib tov nrog dej hauv qhov sib piv ntawm 1: 5 los ua cov pulp. Tom qab lim cov impurities, ntxiv cov nplaum thiab cov dej tsis muaj dej, thiab do kom txog thaum tsis sib xws (li 30 feeb).
2. Moulding thiab ziab
-Mould forming: Txhaj slurry rau hauv aluminium alloy pwm (loj loj 30 × 30cm, ib lub tais tuaj yeem tuav 6-30 qe), lub tshuab nqus tsev adsorption (siab 0.3-0.5MPa).
- Qhuav: Qhuav ntawm qhov kub ntawm 80-100℃rau 2-3 teev, thiab cov ntsiab lus noo noo yuav tsum raug txo kom qis dua 8% (GB/T 6544-2008 tus qauv).
3. Tom qab ua tiav thiab kev tshuaj xyuas zoo
-Tsiming burrs thiab UV sterilization (yuav tsum tau rau qee yam khoom xa tawm).
-Compression test: Cov khoom tsim nyog yuav tsum tiv taus lub siab ntau dua lossis sib npaug rau 200N (kwv yees li 20kg) yam tsis muaj deformation.
3, Innovation thiab Environmental Trends
1. Kev siv cov khoom siv biodegradable: xws li PLA (polylactic acid) trays, nrog rau lub voj voog degradation ntawm 6-12 lub hlis, tab sis tus nqi yog 30% -50% siab dua li cov ntaub so ntswg.
2. Cov txheej txheem txuag hluav taws xob: Microwave ziab tshuab tuaj yeem ua kom lub sijhawm ziab kom luv mus rau 1 teev thiab txo kev siv hluav taws xob los ntawm 40% (cov ntaub ntawv los ntawm: Ntim Engineering, 2022 kev tshawb fawb).
Los ntawm cov txheej txheem saum toj no, kev tsim cov qe tais tuaj yeem ua tiav qhov sib npaug ntawm kev ua haujlwm siab, kev tiv thaiv ib puag ncig, thiab tus nqi qis, ua tau raws li kev xav tau ntawm kev ua lag luam.
