Kev siv tshuaj lom neeg hlau muaj kub zoo thiab tiv taus txias, hardness, tensile lub zog, hluav taws xob rwb thaiv tsev lub zog thiab tawv, thiab muaj cov tshuaj lom neeg ruaj khov, tsis muaj kuab lom rau hauv cov kuab tshuaj organic ntawm chav sov, thiab tiv taus ntau Corrosion los ntawm acid, alkali thiab ntsev kev daws teeb meem, nws tseem muaj qhov zoo heev rau ib puag ncig kev ntxhov siab thiab cov thermal tawg ua kom tawg, siab ntawm lub siab tawv, thiab zoo rau seem ntev. Tshuaj lom neeg hlau nruas tau yooj yim siv, yig thiab siv tau ntev. Nrog txoj kev loj hlob ntawm kev thoob ntiaj teb, yas nruas tau maj mam dhau los ua cov khoom lag luam tseem ceeb rau kev ntim kua. Nws tuaj yeem muaj Chav Kawm II thiab Chav III cov khoom txaus ntshai. Qhov ceev ntawm cov kua uas muaj Class II txaus ntshai cov khoom yog 1.5g / cm3, thiab qhov ntom ntawm cov kua uas muaj Class III phom sij yog 1.8g / cm3. Cov khoom tsim qauv yog qhov tsim nyog, ruaj thiab muaj zog, tuaj yeem ncaj qha thiab tsis ntim nrog lub forklift, thiab tuaj yeem muab ntim thiab khaws cia.
Lub taub ntim yas yog lub teeb thiab tsis yooj yim. Feem ntau ntawm cov tshuaj lom neeg yas thoob, cov tais yas thiab cov raj mis siv rau kev khaws cia khoom noj txhua hnub yog ua los ntawm polyethylene lossis polypropylene, ntawm uas polyethylene muaj ntau dua. Polyvinyl chloride kuj tseem tuaj yeem tsim mus rau hauv cov ntim, cov phiab thiab lwm lub ntim, tab sis zoo li zaj duab xis, nws tsis tuaj yeem tuav zaub mov, tshwj xeeb tshaj yog roj thiab cawv. Tseem muaj cov mem tes-formaldehyde yas feem ntau hu ua" hluav taws xob jade" thiab melamine-formaldehyde yas feem ntau hu ua" melamine", ob qho tag nrho cov uas muaj formaldehyde. Hauv cov txheej txheem ntau lawm, yog tias polymerization tsis zoo, dawb formaldehyde yuav tshwm sim hauv tableware. Formaldehyde yog ib yam tshuaj lom uas lom heev. Yog muab sib xyaw ua ke rau cov zaub mov, nws yuav ua rau tib neeg muaj mob. Yog li ntawd, nws yog qhov tsim nyog los siv qhov zoo" hluav taws xob jade" thiab" melamine" tableware thiab ntim. Rau cov khoom lag luam qis dua, cov tuam tsev tswj hwm yuav tsum nruj tswj hwm lawv kom tiv thaiv lawv ntawm kev tshaj tawm. Txawm hais tias lub thawv polyethylene tuaj yeem siv los tuav cov zaub mov, nws yuav tsum siv los tuav roj. Txij li thaum polyethylene soluble hauv cov roj, yog khaws cia ntev, xim thiab saj ntawm kev ua noj roj yuav hloov, thiab nws yuav txawm siv tsis tau, uas muaj kev phom sij rau kev noj qab haus huv.
