Cov khoom siv rau cov khob yas pov tseg muaj xws li polypropylene (PP), polycarbonate (PC), polyethylene terephthalate (PET), polystyrene (PS), thiab polylactic acid (PLA).
Raws li cov ntaub ntawv yas rov ua dua tshiab, cov khoom siv hluav taws xob sib txawv sib txawv ntawm cov khoom: PP (Code 5) tuaj yeem tiv taus qhov kub txog li 120 degree, thaum PET (Code 1) yog cua sov- tiv taus txog 65℃; PS (Code 6) tiv taus cua sov thiab txias tab sis tsis microwave- nyab xeeb. Compressive zog kuj txawv ntawm cov khoom; Cov khob yas ib txwm siv (xws li cov khoom ua los ntawm PP, PS, lossis PET) muaj lub zog compressive xws li 26 N txog 975 N, qhov PLA khob muaj li ntawm 26 N txog 151 N. Hais txog kev rwb thaiv tsev thermal, cov khob ntawv pov tseg feem ntau ua tau zoo dua cov khob yas pov tseg; corrugated thiab ob npaug -cov khob ntawv hollow phab ntsa muab cov rwb thaiv tsev zoo tshaj plaws, nrog rau qhov kub thiab txias ntawm qhov sib txawv ntawm ntau tshaj 20℃piv rau cov qauv PE-kab khob yas.
Qee lub khob pov tseg tau ua lag luam raws li "degradable" tsis ua kom tawg tag nrho- qhia qhov tawg ntawm 0%- hauv kev sim simulating industrial composting tej yam kev mob, vim muaj xws li tsis yog -degradable PP yas. Cov kev ntsuam xyuas qhia tias tsis muaj microplastic tsiv teb tsaws raug kuaj pom hauv PS, PET, lossis PLA khob kuaj tom qab ob xuab moos ntawm kev tso dej hauv cov dej kub npau npau. Qee cov khoom lag luam tsis zoo ua rau muaj kev pheej hmoo ntawm cov khoom muaj teeb meem ntau dhau; Piv txwv li, cov seem ntau dhau ntawm 3-chloro-1,2-propanediol-chav kawm raws li Pawg 2B "tejzaum carcinogenic rau tib neeg" tshuaj los ntawm International Agency for Research on Cancer (IARC)-tau kuaj pom hauv qee yam khoom.
Cov khob yas yuav tsum ua raws li cov qauv xws li * Kev Nyab Xeeb Khoom Noj Hauv Tebchaws rau Cov Khoom Siv Yas thiab Cov Khoom Uas Yuav Tsum Tau Los Ntawm Cov Khoom Noj * (GB 4806.7) thiab * Cov Khob Dej Haus * (QB/T 4049); Cov cheeb tsam uas tsis yog - ua raws li muaj xws li kev foob kev ncaj ncees thiab kev cuam tshuam.
