Nyob rau lub caij ntuj sov, ib khob dej txias txias tuaj yeem ua rau tib neeg txias tam sim ntawd. Ntxiv rau qhov ua kom zoo nkauj thiab siv tau, lub khob rau cov dej txias yuav tsum muaj kev nyab xeeb thiab zoo ib puag ncig. Niaj hnub no, muaj ntau yam khoom siv rau cov khob pov tseg ntawm kev ua lag luam, txhua tus nrog nws qhov zoo thiab qhov tsis zoo. Niaj hnub no, cia peb tshuaj xyuas ntau yam khoom siv rau cov khob haus dej txias pov tseg.
1. PET khob:
Qhov zoo: siab pob tshab, crystal ntshiab tsos, tuaj yeem pom cov xim zoo nkauj; siab hardness, tsis yooj yim rau deform, nyiam kov; tus nqi qis, haum rau tuav ntau yam dej txias, xws li kua txiv hmab txiv ntoo, mis nyuj tshuaj yej, kas fes, thiab lwm yam.
Qhov tsis zoo: Cov cua sov tsis zoo, feem ntau tsuas tuaj yeem tiv taus qhov kub siab tshaj 70 ℃, tsis haum rau tuav cov dej kub.
Cov tswv yim yuav khoom: Xaivzaub mov qib tsiaj khobcim "PET" lossis "1", tsis txhob siv lub khob PET qis dua, thiab tsis txhob siv lub khob PET los tuav cov dej kub.
2. Ntawv khob:
Qhov zoo: Ib puag ncig tus phooj ywg thiab degradable, zoo luam ntawv nyhuv, xis nyob, haum rau cov dej txias xws li kua txiv hmab txiv ntoo, mis nyuj tshuaj yej, thiab lwm yam.
Qhov tsis zoo: Ib qho yooj yim rau soften thiab deform tom qab lub sij hawm ntev cia, thiab ib co ntawv khob yog coated nrog ib tug yas txheej nyob rau hauv lub puab phab ntsa, uas cuam tshuam rau degradation.
Cov tswv yim yuav khoom: Xaivdaim ntawv khob ua los ntawm cov ntawv nyoos pulp, thiab sim xaiv ib puag ncig tus phooj ywg lub khob khob tsis muaj txheej txheej lossis txheej txheej degradable.
3. PLA degradable khob:
Qhov zoo: Ua los ntawm cov khoom siv txuas ntxiv mus ntxiv (xws li pob kws hmoov txhuv nplej siab), ib puag ncig tus phooj ywg thiab degradable, zoo tiv thaiv tshav kub, tuaj yeem tuav dej kub thiab txias.
Disadvantages: Tus nqi siab, tsis yog pob tshab li lub khob yas, tsis zoo rau lub caij nplooj zeeg.
Cov tswv yim yuav khoom: Cov neeg siv khoom uas them nyiaj rau kev tiv thaiv ib puag ncig tuaj yeem xaivPLA degradable khob, tab sis xyuam xim rau lawv cov kev poob qis tsis zoo kom tsis txhob poob.
4. Bagasse khob:
Qhov zoo: Ua los ntawm bagasse, ib puag ncig tus phooj ywg thiab degradable, tsis muaj tshuaj lom thiab tsis muaj mob, tuaj yeem tuav dej kub thiab txias.
Disadvantages: Rough tsos, tus nqi siab.
Cov tswv yim yuav khoom: Cov neeg siv khoom uas them nyiaj rau kev tiv thaiv ib puag ncig thiab nrhiav cov khoom siv ntuj tuaj yeem xaivbagasse khob.
Cov ntsiab lus:
Cov khob pov tseg ntawm cov khoom sib txawv muaj lawv qhov zoo thiab qhov tsis zoo. Cov neeg siv khoom tuaj yeem xaiv raws li lawv tus kheej xav tau thiab cov ntsiab lus tiv thaiv ib puag ncig.
Rau kev ua tau zoo thiab siv tau zoo, koj tuaj yeem xaiv PET khob lossis khob ntawv.
Rau kev tiv thaiv ib puag ncig, koj tuaj yeem xaiv PLA degradable khob, bagasse khob, thiab lwm yam khoom siv degradable.
