Sib nrug ntawm PVC, peb kuj tsim cov ntawv ua los ntawm polycarbonate (PC) thiab Polyethylene Terephthalate Glycol (PETG). Ob yam khoom yas no ua rau cov ntawv no tiv taus cua sov.

Yog li, PETG yog dab tsi thiab vim li cas koj yuav tsum xav txog nws rau koj daim npav yas? Txaus siab txaus, PETG yog ua los ntawm polyester (kom meej meej, thermoplastic copolyester) tsis yog PVC, thiab nws yog 100 feem pua ​​​​​​rov ua dua tshiab THIAB biodegradable. Txawm li cas los xij, nws tseem ua haujlwm zoo li PVC, yog li nws ruaj khov thiab tiv taus kev cuam tshuam. Kev luam ntawv nrog PETG yooj yim thiab cov qauv tsim zoo nkauj heev! Saib seb cov qauv tsim zoo li cas ntawm PETG.

Yog li ntawd, daim npav PC thiab PETG yog qhov tsim nyog rau thaj chaw kub, piv txwv li United Arab Emirates lossis South America, qhov twg qhov kub thiab txias thaum lub caij ntuj sov tuaj yeem nce mus txog 40 degrees Celsius, lossis txawm tias mus txog 65 degree Celsius hauv tsheb. PVC pib yaj ntawm 60 degrees.

Peb daim npav PC thiab PETG tiv taus cua sov txog li 120 degrees Celsius. Qhov ntawd txhais tau tias, nyob rau qee qhov huab cua hnyav, daim npav ID raug cai tuaj yeem tso tseg hauv lub tsheb thaum lub sijhawm so noj su yam tsis tas txhawj txog nws, thiab lub tshuab ua daim npav hauv chaw nres tsheb Toronto tsis tas yuav tsum tau muab pov tseg kom txog thaum yav tsaus ntuj. Cov npav no kuj ruaj khov heev, yog li lawv tuaj yeem siv tau txog li kaum xyoo.

Peb yuav ua qhov zoo tshaj plaws kom txuas ntxiv ua kom tau raws li peb cov neeg siv khoom xav tau los ntawm kev txuas ntxiv tsim kho, tsim khoom thiab muab cov khoom lag luam tshiab thiab zoo.
