Txoj Kev Txhim Kho Cov Khoom Siv Yas

Txoj kev loj hlob ntawm cov yas tuaj yeem muab faib ua ob yam. Ib qho yog txhawm rau txhim kho kev ua tau zoo, uas yog, hloov kho ntau yam uas twb muaj lawm hauv ntau txoj hauv kev los txhim kho lawv cov kev ua tau zoo; lwm qhov yog los tsim cov haujlwm, uas yog, tsim cov khoom siv polymer nrog lub cev ua haujlwm xws li lub teeb, hluav taws xob, thiab hlau nplaum, kom cov yas tuaj yeem muaj cov nyhuv Photoelectric, pyroelectric effect, piezoelectric effect, thiab lwm yam.

Kev txiav txim siab los ntawm kev loj hlob tam sim no ntawm lub ntiaj teb kev lag luam plastics, lub teb chaws Yelemees thiab Sweden yog thawj, ua raws li Nyiv thiab qee lub tebchaws nyob sab Europe, thiab Tebchaws Meskas qeeb dua. Cov ntim yas txawv teb chaws nthuav tawm cov kev txhim kho hauv qab no:

1. Copolymer composite ntim zaj duab xis

Tam sim no, qee lub tebchaws hauv Tebchaws Europe thiab Tebchaws Meskas tau nqis peev ntau rau hauv kev tsim cov non-polar thiab polar ethylene copolymer, uas yuav ua kom zoo dua tensile thiab co-extrusion zog ntawm cov yas zaj duab xis, thiab txhim kho pob tshab, sealing zog, kev nyuaj siab. , tawg tsis kam, thiab txhim khu kev ruaj ntseg. , Txhim kho molecular hnyav daim ntaub thiab extrusion rheological zog.

Cov kws tshaj lij txawv teb chaws ntseeg tias tam sim no txoj kev loj hlob ntawm lub ntiaj teb plastics kev lag luam tsom mus rau kev hloov kho yas, txheej tshuab rau cov khoom yas, biodegradation sai ntawm cov khib nyiab plastics, thiab kev siv thev naus laus zis rau cov yas rov ua dua tshiab. Piv txwv li, qee cov tuam txhab nyob sab Europe thiab Asmeskas siv linear ethylene-alpha olefin copolymer thiab ethylene-vinyl acetate copolymer tov / PA hnab, uas yog tsim rau ntim ice cream, mis nyuj rog thiab lwm yam khoom noj.

2. Multifunctional composite zaj duab xis

Ntau lub teb chaws txawv teb chaws tau tsim cov yeeb yaj kiab sib xyaw ua ke los ua kom zoo dua lawv txoj haujlwm. Piv txwv li, cov yeeb yaj kiab uas tiv taus txias tuaj yeem tiv taus qhov kub thiab txias ib puag ncig ntawm -18 degree , -20 degree , thiab -35 degree ; PP zaj duab xis yog ua los ntawm cov dej noo-pov thawj yog kho nrog dej-pov thawj, thiab nws cov khoom lag luam tuaj yeem muab faib ua cov dej-pov thawj, tiv thaiv condensation, tiv thaiv chav txias, thiab kho cov dej noo. Anti-corrosion zaj duab xis tuaj yeem ntim perishable, siab acidity thiab khoom noj qab zib; kev sib txhuam zaj duab xis yog ruaj khov nyob rau hauv stacking; tshwj xeeb PE zaj duab xis yog tshuaj thiab corrosion resistant; npauj-pov thawj zaj duab xis yog ntxiv nrog tsis muaj ntxhiab tsw thiab tshuaj tua kab; Lub tshav kub-resistant zaj duab xis ntawm stretched nylon 66 hloov biaxially oriented nylon 6 rau ntim khoom noj, thiab nws kub kuj muaj peev xwm ncav cuag 140 degree; cov yeeb yaj kiab tshwj xeeb ntim khoom noj tshiab tuaj yeem txhim kho qhov tsw qab ntawm cov ntim khoom noj; lub pob tshab ntawm amorphous nylon zaj duab xis zoo ib yam li iav; lub siab shielding zaj duab xis tuaj yeem tiv thaiv Kev ruaj ntseg ntawm cov xim, aroma, saj, noj zaub mov Performance index thiab saj zoo; hlau tiv thaiv zaj duab xis txais LDPE hloov zaj duab xis los ntim cov khoom ua kua, uas tuaj yeem ua kom sov-sau hauv qhov kub thiab txias; PP cov ntawv hluavtaws txhim kho lub teeb ua haujlwm, tiv thaiv txias thiab ua haujlwm ntawm pob. Thaum tshav kub kub tsis kam, dej tsis kam, noo noo tsis kam, roj tsis kam, acid tsis kam, alkali tsis kam thiab cuam tshuam tsis kam, thiab lwm yam.

Tam sim no, cov khob yas thiab cov khob sib xyaw ua ke ( txheej txheej PSP, txheej sab hauv PP, lub hau PS) yog nrov nyob rau txawv teb chaws los ntim cov dej txias thiab kub, cawv thiab khoom noj tam sim. Fabkis siv PE fwj los ntim fructose thiab yogurt, thiab lub teb chaws Yelemees siv PC fwj los ntim mis nyuj. kuv lub teb chaws siv PE fwj los ntim tshuaj, thiab lwm yam.
