Ib, Cov Yam Ntxim Saib Ntxim Ua: cuam tshuam kev tsim kho tshiab los ntawm "Irreversible Pollution" mus rau "Natural Circulation"
1. Cov khoom siv raw los ntawm qhov twg thiab lawv kav ntev npaum li cas
Moulded pulp yog tsim los ntawm kev ua liaj ua teb pov tseg xws li xyoob pulp, bagasse, thiab cov ntawv pov tseg. Ntau tshaj 95% ntawm nws tuaj yeem rov ua dua tshiab, tsim kom muaj kev kaw -voj kev lag luam saw. Piv txwv li, kev rov ua dua qub cov thawv ntawv los ua cov qe pwm tuaj yeem pab kev lag luam txiav ntoo los ntawm 0.8 cubic meters rau txhua tuj ntawm cov qe pwm nws ua. EPS (polystyrene ua npuas ncauj), ntawm qhov tod tes, yog tsim los ntawm roj av-raws li cov khoom xyaw nyoos. Nws yuav siv 1.5 tons ntawm cov roj crude los ua ib tuj ntawm EPS, thiab cov khoom siv raw no tsis tuaj yeem rov qab siv dua. EPE (polyethylene ua npuas ncauj) siv qee cov khoom siv rov ua dua tshiab, txawm li cas los xij nws tsuas yog rov ua dua tsawg dua 30% ntawm lawv, thiab kev ua haujlwm ntawm cov khoom noj nyoos tau poob qis heev.
2. Kev ua tau zoo ntawm degradation thiab lifespan
Hauv cov tsiaj qus, cov khoom lag luam pwm tuaj yeem tawg tag nrho rau hauv dej thiab carbon dioxide hauv 90 hnub. Yog tias koj ua chiv rau hauv tsev, cov txheej txheem tuaj yeem ncav cuag 45 hnub. Tej yam uas ua rau nws tsis muaj teeb meem thiab tuaj yeem koom nrog hauv ecological cycles. EPS, ntawm qhov tod tes, siv sijhawm ntau pua xyoo los rhuav tshem, thiab cov khoom siv microplastic uas tau tawm hauv cov txheej txheem no tsim nyob rau hauv cov khoom noj. EPE tawg me ntsis sai dua EPS, tab sis nws tseem siv sijhawm ntau dua 50 xyoo. Kev kub hnyiab tuaj yeem ua rau cov tshuaj txaus ntshai heev xws li dioxins.
3. Kev nyab xeeb ntawm cov tshuaj thiab ua raws li cov cai ntawm kev sib cuag zaub mov
Adding natural waterproofing agents like beeswax and starch-based coatings to molded pulp can make it IP67 waterproof and moisture-proof. It also fulfills FDA criteria for food contact. One kind of frozen food box uses modified pulp molding technique that keeps the structure stable between -40 and 220 degrees Celsius without the risk of chemicals moving around. EPS can let styrene monomers out when the temperature is high (>80 degree), thiab EPE tuaj yeem tso cov yas yas tawm thaum nws los rau hauv kev sib cuag nrog cov roj thiab cov rog ntev. Ob qho no yog qhov txaus ntshai rau kev nyab xeeb zaub mov.
2, Cov txheej txheem logic: kev ua tau zoo los ntawm "passive buffering" mus rau "kev tsim muaj zog"
1. Rebuilding buffering kev ua tau zoo mechanically
Kev ntim khoom ua npuas ncauj siv cov khoom siv khoov kom nqus tau lub zog. Nws tuaj yeem muab cov cushioning ceev vim tias nws muaj cov qauv kaw ntawm tes, tab sis nws tsis lo zoo rau cov qauv uas nyuaj. Piv txwv li, thaum koj siv EPS los ntim cov khoom siv hluav taws xob, koj xav tau cov npuas npuas ntxiv, uas nce tus nqi tag nrho los ntawm 30%. Moulded pulp muaj peb - qhov ntev fiber ntau qauv uas zoo li lub honeycomb thiab tuaj yeem tuav txog 50 kg / ㎡ ntawm qhov hnyav. Nws tseem tuaj yeem ua tau zoo kawg nkaus rau kev tsim cov khoom siv 3D pwm. Tom qab qee lub tsheb qhov chaw tsim khoom tau pib siv cov khoom siv hauv cov khoom siv pwm, tus nqi ntawm kev puas tsuaj thaum thauj mus los ntawm 2.3% mus rau 0.15%.
2. Muaj peev xwm hloov tau raws li qhov sib txawv
Moulded pulp tuaj yeem ua tiav ntau yam ntawm kev xav tau los ntawm kev hloov txoj kev nws ua:
Nyob rau hauv qhov kub ntawm - qhov kub thiab txias, siv cov khoom siv hluav taws xob tsis zoo tuaj yeem nce qhov hluav taws kub mus rau 1200 degree, uas yog qhov zoo rau kev ntim cov khoom siv hluav taws xob.
Hauv qhov xwm txheej tiv thaiv - zoo li qub, ntxiv cov khoom siv hluav taws xob tuaj yeem ua kom lub ntsej muag tiv thaiv ntawm 10 6 thiab 10 9 Ω, uas yog yam khoom siv hluav taws xob yuav tsum tau ua los tiv thaiv - zoo li qub.
Qhov xwm txheej tshiab rau khaws cia zaub mov: Cov qauv fiber ntau tso cua los ntawm tus nqi ntawm 800g / m² ib 24 teev. Zaj duab xis npog tshuab tuaj yeem hloov pauv qhov ua pa, uas tuaj yeem ua rau cov txiv hmab txiv ntoo thiab zaub kav ntev li 3 txog 5 hnub.
3. Yooj yim rau pawg thiab lub teeb yuag
Qhov ceev ntawm molded pulp khoom yog tsuas yog 0.3-0.5g / cm³, uas yog me ntsis siab dua EPS (0.02-0.03g / cm³), tab sis lub foldable tsim ua rau feem ntau ntawm cov cheeb tsam. Piv txwv li, ib hom pulp molded qe tais muaj cov qauv nested uas ua rau stacking 30% ntau npaum li EPS qe tais thiab tso cai rau 25% ntau lub peev xwm thauj mus rau hauv ib lub thawv. Tsis tas li ntawd, cov khoom siv pulp molded tuaj yeem txo qis ntawm qhov chaw cia los ntawm ib nrab, uas txo cov nqi logistical los ntawm ntau tus nqi.
3, Kev Lag Luam Kev Lag Luam: Kev hloov pauv los ntawm "Txoj Cai Tsav Tsheb" mus rau "Tus Nqi Them Rov Qab" hauv kev lag luam
1. Tso tawm cov nyiaj faib tawm txoj cai
Kev txwv thoob ntiaj teb rau cov yas yog nrawm dua. EU's "Plastic Disposable Directive" hais tias EPS ntim khoom noj yuav tsum raug txwv tsis pub dhau xyoo 2030. Tuam Tshoj txoj "14th Tsib Xyoo Npaj" rau kev tsim kev lag luam ncig hais txog kev tsim cov pulp yog ib qho ntawm cov khoom tseem ceeb los txhawb. Cov tuam txhab tshawb fawb kev lag luam hais tias los ntawm 2025, kev lag luam thoob ntiaj teb pulp molding yuav muaj nqis tshaj $ 12 nphom thiab yuav nthuav dav ntawm 15% hauv ib xyoos. Ntawm qhov tod tes, EPS / EPE kev ua lag luam yuav poob 3% hauv ib xyoos.
2. Ua kom tus nqi zoo dua
Tus nqi ntawm pulp molding ib tuj tau poob mus rau 17500 yuan, uas yog hais txog tib yam li EPS (16000 yuan / tuj). Txawm li cas los xij, cov txiaj ntsig tag nrho yog qhov loj:
Tus nqi thauj mus los: Tus nqi ntawm cov khoom siv molded yog 40% tsawg dua EPS, txawm li cas los xij tus nqi ntawm ib qho kev thauj mus los yog 60% ntau dua;
Tus nqi cia: Daim ntawv foldable ua rau qhov chaw cia peb zaug ntau dua;
Tus nqi pov tseg: Tus nqi ntawm cov khoom pov tseg rov ua dua tshiab yog 800 yuan ib tuj, hos tus nqi ntawm kev rov ua dua EPS tsawg dua 200 yuan ib tuj. Qhov no txhais tau tias cov nqi ua haujlwm kim yuav tsum tau them.
3. Muab lub hwj chim rau hom khoom muaj nqis
Raws li tib neeg xav txog ib puag ncig, "green premium" pib tshwm sim. Kev tshawb fawb pom tias 78% ntawm cov tib neeg yuav them 10% mus rau 20% ntxiv rau eco- ntim khoom zoo. Apple tau hloov pauv tag nrho rau cov khoom siv molded tais rau nws lub ntim iPhone. Qhov no tau txiav cov pa roj carbon hneev taw ntawm txhua pob los ntawm 45% thiab ua rau lub npe nrov dua los ntawm 22 feem pua cov ntsiab lus.
4, Kev txiav ntug ntawm thev naus laus zis: txoj hauv kev los ntawm "kev hloov pauv" mus rau "kev ua tau zoo tshaj"
Pulp molding thev naus laus zis tam sim no tau nce mus rau qhov raug siab thiab ntau txoj haujlwm:
3D pwm raug: Nrog tsib -axis CNC machining, pwm yuam kev yog khaws cia nyob rau hauv ± 0.1 hli, uas yog zoo txaus rau ntim cov kev xav tau ntawm precision instruments.
Kev siv cov khoom siv sib xyaw: Thaum cov khoom siv biobased xws li PLA sib xyaw nrog cov khoom, nws dhau los ua peb zaug thiab tsis muaj dej tsis zoo rau qib IPX5.
Kev ntim khoom ntse: RFID cim npe lossis ntsuas kub thiab av noo tuaj yeem ua rau hauv lub ntim kom muab tag nrho traceability thiab tswj kom zoo thoob plaws hauv cov khoom siv.
