一,Technical hauv paus ntsiab lus: Yuav ua li cas ya raws - cov tshuaj pov thawj tuaj yeem tiv thaiv cov tawv nqaij los ntawm kev ntub dej noo
Nroj fibers nrog rau cov ntawv pov tseg, qab zib bagasse, thiab xyoob fiber ntau yog cov khoom siv raw rau molding pulp. Vim yog pawg hydroxyl (- OH) hauv nws cov qauv molecular, cov khoom siv yog hydrophilic heev, uas txhais tau hais tias nws tuaj yeem nqus tau noo noo yooj yim hauv qhov chaw ntub dej. Qhov no tuaj yeem ua rau muaj teeb meem nrog rau kev hloov pauv loj thiab lub zog. Cov dej noo-cov pov thawj ua pov thawj tsim hydrophobic barriers ntawm cov fibers los ntawm kev sib tshuam ntawm lub cev lossis tshuaj lom neeg. Qhov no txwv cov dej molecules los ntawm kev hla thiab ua rau cov ntaub ntawv tiv taus cov dej noo.
1. Moisture-cov pov thawj uas ua haujlwm raws li lub cev thaiv
Paraffin lotion thiab silicone lotion yog cov piv txwv ntawm yuav ua li cas ib tug nruam hydrophobic zaj duab xis yog generated ntawm fibers los ntawm mechanically txheej los yog ntxiv rau lub pulp. Piv txwv li, yog tias koj ntxiv paraffin lotion rau lub pulp ntawm tus nqi ntawm 0.5% mus rau 3% ntawm nws qhov hnyav qhuav, koj tuaj yeem ua ib txheej tuab tuab ntawm cov fiber ntau uas txiav cov khoom nqus dej ntau dua 60%. Cov dej noo zoo li no - cov tshuaj pov thawj ua haujlwm zoo rau cov khoom xws li ntim cov zaub mov thiab cov tais diav pov tseg. Qhov zoo tshaj plaws txog nws yog tias nws pheej yig thiab siv tau yooj yim, tab sis nws tsis tuav zoo ntawm qhov kub thiab txias.
2. Cov dej noo- pov thawj tus neeg sawv cev uas tau hloov pauv tshuaj
Acrylic waterproofing agents chemically reacts nrog fibers los tsim ib tug polymer txheej rau saum npoo. Piv txwv li, cov dej tsis sib haum MX-525B muaj cov qauv nanoscale molecular uas tuaj yeem tau txais hauv fibers thiab tsim cov kev sib txuas ruaj khov nrog cov pab pawg hydroxyl. Qhov no ua rau cov khoom ruaj khov txawm tias cov av noo yog 85%. Cov dej noo zoo li no-cov ntaub ntawv pov thawj yog huab cua heev- tiv taus thiab yog qhov zoo rau kev ntim khoom siab-kawg hluav taws xob, khoom siv kho mob, thiab lwm yam uas yuav tsum tau muaj dej noo ntau.
3. Lub kaw lus uas tiv thaiv kev ya raws hauv kev sib xyaw
Los ntawm kev siv ob qho tib si lub cev tiv thaiv thiab kev hloov tshuaj lom neeg, ntau- txheej txheej lossis kev sib xyaw tuaj yeem ua rau cov khoom ua haujlwm zoo ua ke. Piv txwv li, ib lub tuam txhab tau tsim cov dej noo- pov thawj tus neeg sawv cev hu ua "wax lotion+acrylate" uas tau nce nws cov dej noo- pov thawj kev ua tau zoo los ntawm 80% tom qab tau siv rau hauv cov khoom noj khoom haus molded, thaum tseem ua tau raws li cov cai tswj kev nyab xeeb khoom noj.
2, Daim ntawv thov rooj plaub: Cov xwm txheej sib txawv uas cov dej noo- pov thawj cov neeg ua haujlwm pab pwm pwm
1. Ntim rau high -kawg electronics
Lub Lenovo ThinkPad X1 series ntawm lub laptops siv cov ntaub pua plag molding ua los ntawm cov txheej txheem ntub dej. Ntxiv 0.8% acrylate noo noo-cov ntaub ntawv pov thawj ua rau cov khoom siv compressive zog tuav tus nqi 92% nyob rau hauv ib puag ncig nrog 95% av noo. Qhov no tau ua tiav hloov cov txheej txheem EPS ua npuas ncauj thiab txiav cov pa roj carbon hneev taw los ntawm 40%. Apple Beats Studio Pro earbuds tuaj hauv ib pob ua los ntawm kev sib xyaw ntawm cov xyoob fiber ntau thiab cov dej noo- cov ntaub ntawv pov thawj. Cov pob no muaj lub zog compressive ntawm 120kPa thiab tau dhau FDA daim ntawv pov thawj, uas txhais tau tias nws tuaj yeem muag hauv txhua lub tebchaws.
2. Lub ntsiab lus ntawm kev ntim khoom noj
Ib lub tuam txhab tau tsim cov txheej txheem kev tiv thaiv kev tiv thaiv ob qho tib si hu ua "starch modification + paraffin lotion" kom ua tau raws li cov kev xav tau ntawm kev lag luam khoom noj ceev ceev rau kev tiv thaiv roj thiab noo noo. Hla - txuas cov tshuaj tiv thaiv txo cov dej noo nqus ntawm cov hmoov txhuv nplej siab. Tom qab ntawd, paraffin lotion yog siv los tsim ib txheej hydrophobic ntawm qhov chaw. Qhov no txhais tau hais tias lub pulp molded noj su lub thawv tsis xau thaum nws los rau hauv kev sib cuag nrog cov roj kub ntawm 80 degree. Nws kuj tseem tuaj yeem tawg tau tag nrho, ua rau nws yog tus xa khoom tseem ceeb ntawm kev ntim khoom ib puag ncig rau McDonald's, KFC, thiab lwm lub npe.
3. Ntim rau kev lag luam buffers
Thaum nws los txog rau kev thauj cov cuab yeej precision, siv cov dej noo- cov ntaub ntawv pov thawj thiab molded pulp ua ke ua rau cov khoom ruaj khov dua. Piv txwv li, ib lub tuam txhab logistics ua hauj lwm cov tais ua los ntawm cov tawv nqaij nrog cov dej noo- cov tshuaj pov thawj kom txav LCD panels. Hauv kev simulated ntsev tsuag kev sim ntawm kev thauj mus los hauv hiav txwv, cov khoom siv noo noo nqus tau poob los ntawm 75% piv rau cov qauv tsis kho, thiab qhov kev puas tsuaj poob los ntawm 1.2% mus rau 0.3%. Qhov no tau cawm ntau dua 2 lab yuan hauv cov nqi them txhua xyoo.
3, Kev lag luam tus qauv: ib qho txheej txheem ntawm cov qauv thiab cov ntawv pov thawj rau kev siv cov dej noo- cov ntaub ntawv pov thawj
1. Cov qauv rau kev nyab xeeb zaub mov
Khoom noj khoom haus sib cuag molded pulp yuav tsum tau raws li cov qauv teev los ntawm GB 4806.7-2023, "National Food Safety Standard for Food Contact Paper and Paperboard Materials and Products." Cov ya raws inhibitor qhov chaw yuav tsum dhau qhov kev kuaj kev tsiv teb tsaws chaw. Piv txwv li, SGS kuaj pom tias MX-525B waterproofing tus neeg saib xyuas tsis suav nrog hnyav hlau, formaldehyde, fluorescent brightening agents, los yog lwm yam teeb meem. Qhov no txhais tau hais tias nws muaj kev nyab xeeb rau kev siv hauv ntim khoom noj thiab cov tais diav.
2. Daim ntawv pov thawj rau ib puag ncig
Txoj cai EU REACH thiab US FSC ntawv pov thawj muaj cov cai nruj heev txog yuav ua li cas biodegradable ya raws -cov pov thawj yuav tsum yog. Piv txwv li, ib lub tuam txhab tau ua cov hmoov txhuv nplej siab -raws li cov dej noo- pov thawj tus neeg sawv cev uas tawg 92% ntawm lub sijhawm hauv 60 hnub ntawm kev tsim cov chiv thiab tau txais T Ü V Austria "OK compost" ntawv pov thawj. Qhov no ua rau nws thawj Suav ib puag ncig ntim khoom lag luam nkag mus rau European lag luam.
3. Cov qauv ntsuas kev ua tau zoo
Feem ntau ntawm lub sijhawm, kev lag luam ntiav ASTM D570 "Plastic Water Absorption Test Method" los ntsuam xyuas seb cov pulp zoo li cas tuaj yeem tiv taus noo noo. Qhov kev sim no xav kom cov pulp muaj qhov sib npaug ntawm qhov nqus dej tsawg dua lossis sib npaug li 5% ntawm 23℃thiab 50% av noo. ISTA 3A kev kuaj tsheb thauj mus los yog xav tau nyob rau hauv siab -kawg lag luam kom ua raws li cov xwm txheej hnyav xws li tee, kev vibrations, kub thiab av noo hloov, thiab kom paub tseeb tias cov dej noo- pov thawj tshuaj thiab cov khoom ua haujlwm zoo ua ke.
