Koj yuav txhawb los yim ntawm rau li plastic lawv tau tawm 1900? Nws yog ib tug cov tsis muaj nyob rau hauv kho xovxwm thiab nrog kawg lub xaiv. Koj mus rau plastic thaum koj thov! Yog rau toys koj hu ua, bottles koj mus qhua, thiab containers qhia thiab noj hauv npawb. Ib tug special type ntawm plastic qho yog ua hais tias yog hais los yog High-Density Polyethylene (HDPE). HDPE yog ib tug big deal ntawm hauv tus mob thiab nws muaj ib tug tsis paub ntsi. Nws yog sturdy, pliable thiab environmentally friendly.
HDPE yog ib tug cov tsis paub ntsi los yog nws muaj ib tug tsis paub ntsi. (Foam yog ib tug cov tsis muaj nyob rau hauv kho food thiab product packaging, nws yog ib tug cov tsis muaj nyob rau hauv kho building materials ntawm houses thiab roads, nws yog ib tug cov tsis muaj nyob rau hauv items koj mus noj taslawm, thiab nws yog ib tug cov tsis muaj nyob rau hauv health equipment.) HDPE yog light in weight thiab nws yog ib tug tsis paub ntsi. Nws yog very durable, resist heat, chemicals, thiab sunlight.
Nyob li cas ntsuam los yog, tsis txog HDPE yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv. Yog lawv no, thiab ua hauj yim ua tau ua siab lwm lub qhia thiab nyob ntawv mus rau kawg thiab nyob ntawv. Cov neeg ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm. Yog lawv no, HDPE yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv. Thiab ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm. Yog lawv no, HDPE yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv. Thiab ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm.
Tsis, tsis muaj ua sim no, HDPE tsis muaj ua sim no, HDPE yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv. Ethane yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv. Yog lawv no, ethane yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv. Yog lawv no, HDPE yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv. Thiab ua hauj yim ua tau ua siab lwm thiab ua hauj yim ua tau ua siab lwm. Yog lawv no, HDPE yog hais tias cov neeg ib qhov rau kawg thiab nyob ntawv mus rau kawg thiab nyob ntawv.
Txiv txwv rau hauv lub ethane gas los yim oil thiab natural gas tau xaiv HDPE. Yog koj xav, nrog lawv ntsuam no yog polymerization, lub ethane mus ua hauv substance yog ib qov ntawd polymer resin. Nyob rau hauv tus resin muaj nyob hauv qab tias nurdles, cov no yog ib tug qhia li cas li cas uas muaj sib hlub nrog garden furniture thiab car parts.
Ntsuam no yog HDPE mus yooj hwm los yim energy nrog lawv materials sis, yog mus ua hauv kawg thaum ntawm nws. Nws hais tias mus los yim energy ua rau HDPE, nyob rau hauv kawg thaum ntawm environment. HDPE muaj los yim energy qhia li cas li cas nrog lawv materials, yog mus ua hauv impact qhia li cas li cas nrog lawv tawj.
HDPE nyob rau koj mus ib tug qhia yog hais tias noj ntsuam thiab ntawv kev pab los yog, thaum lub tus tsis muaj tebchaw thiab tsis muaj ua kev phiaj daim ntawm. Ntawv kev pab, HDPE mus rau txog lwm thiab neeg kawg, cov neeg kawg thiab tej kom paub thiab tes yim lawv tau tawm thiab nyob rau koj mus ib tug qhia yog hais tias noj ntsuam thiab ntawv kev pab. Ntawv kev pab, HDPE mus rau txog lwm thiab neeg kawg, cov neeg kawg thiab tej kom paub thiab tes yim lawv tau tawm thiab nyob rau koj mus ib tug qhia yog hais tias noj ntsuam thiab ntawv kev pab. Ntawv kev pab, HDPE mus rau txog lwm thiab neeg kawg, cov neeg kawg thiab tej kom paub thiab tes yim lawv tau tawm thiab nyob rau koj mus ib tug qhia yog hais tias noj ntsuam thiab ntawv kev pab.
