Eco Friendly PLA Yas Hnab Biodegradable Ntim Hnab

Nws yog ib lub hnab yas ua los ntawm cov yas degradable:
1.Degradable plastics:
Cov yas degradable yog hais txog qee yam ntawm cov khoom ntxiv (xws li cov hmoov txhuv nplej siab, hloov cov hmoov txhuv nplej siab lossis lwm yam cellulose, photosensitizers, biodegradants, thiab lwm yam) ntxiv rau hauv cov txheej txheem tsim khoom kom txo tau nws qhov kev ruaj ntseg thiab tom qab ntawd yooj yim degrade nyob rau hauv ib puag ncig ntuj.
2. Classification:
Degradable plastics feem ntau muab faib ua plaub pawg:
① Yees duab degradable yas
Siv cov photosensitizer rau hauv cov yas, cov yas yog maj mam decomposed nyob rau hauv tshav ntuj. Nws belongs rau tiam dhau los ntawm cov yas degradable, thiab nws qhov tsis zoo yog tias lub sij hawm degradation yog qhov nyuaj rau kwv yees vim kev hloov ntawm lub hnub ci thiab huab cua, yog li lub sij hawm degradation tsis tuaj yeem tswj tau.
② Biodegradable plastics
Cov nyhuv xav tau yog cov yas uas tuaj yeem ua tiav raws li pawg tshuaj molecular. Nrog rau niaj hnub biotechnology, ntau thiab ntau cov xim tau them rau biodegradable plastics, uas tau dhau los ua qauv ntawm kev tshawb fawb thiab kev loj hlob.
③ Lub teeb / biodegradable yas
Ib hom yas uas ua ke nrog photodegradation thiab microorganisms, nws muaj cov yam ntxwv ntawm lub teeb thiab microorganism degradable plastics tib lub sijhawm.
④ Dej-degradable plastics
Ntxiv dej-absorbing tshuaj rau cov yas, uas tuaj yeem yaj hauv dej tom qab siv. Nws yog tsuas yog siv rau hauv cov khoom siv kho mob thiab tshuaj ntxuav tes (xws li hnab looj tes kho mob), uas yooj yim rau kev puas tsuaj thiab tua kab mob.
3. Taw qhia:
Kev ntsuam xyuas tau pom tias feem ntau cov plastics degradable pib thinning, poob yuag, poob lub zog, thiab maj mam tawg mus rau hauv daim tom qab 3 lub hlis ntawm kev raug rau hauv ib puag ncig. Yog tias cov khoom tawg no tau faus rau hauv cov khib nyiab lossis av, cov nyhuv degradation tsis pom tseeb.
