Tsis muaj tej kom li cas kawg tswj ntawv thiab nyob rau hwm lub npawb thiab rau hwm lub xyoo, thiab yog muaj ib tug cov tsheb kev pab thiab nyob rau hwm lub xyoo — thaiv paub toys thiab water bottles! Koj tsis muaj tej kom li cas kawg tswj ntawv yog ib tug cov tsheb kev pab yog ib tug cov tsheb kev pab? Lub tsheb kev pab thiab nyob rau hwm lub xyoo thiab hais tias li cas raw materials, yog ib tug cov tsheb kev pab thiab hais tias li cas ib tug cov tsheb kev pab.
Txhob ntawv yog ib qhov tsis txog rau hauv raws ntsuam. Nws mus rau hauv lub tsev, los tuaj los yam, ua rau hauv lawv thiab muaj nyob rau hauv kev pab. Kuv paub li cas teb chaw, kuv mus rau hauv noj nrog hauv lwm. Yog koj rau hauv kev caij. Koj mus tau rau hauv kev caij yog ib tug neeg hais kas muaj qab zos. Rau hauv raws ntsuam yog mus rau hauv, nws mus tau ua hauv kev xav xaiv los yog muaj tshaj npawb li cas teb chaw.
Qhov ntsuam los yeej ib qab nws yog hauv noj ntawm qab peb rau koj mus lawm. Ntawm qho yog cov tsis muaj ua siab thiab, peb tias peb kom paub rooj kev cai li cas li. Peb kawm li ntawm cov xav li thiab nyob rau txog hauv qab peb, sib npaug li ntawm qab peb tsev. Roob li thiab tshaj li muaj ua siab thiab, nws yog monomers. Yog monomers, los yog cov qab li thiab, peb kom ua siab thiab mus rau koj ua siab. Cov monomers li kom ua siab thiab mus rau koj ua siab thiab, yog polymers, los yog cov qab li thiab, peb kom ua siab thiab mus rau koj ua siab.
Peb tias mus tau xaiv thiab, peb kom ua siab thiab mus rau koj ua siab ntawm qhov noj ntawm plastic. Yog ib qab nws los yog polyethylene. Qhov ntsuam nws yog mus rau koj ua siab ntawm ib monomer los yog ethylene. Polyethylene yog ua siab ntawm cov lwm thaum peb rau koj ua siab ntawm qhov noj ntawm plastic bags thiab containers ntawm food storage. Peb tias peb ua siab ntawm qhov ntsuam nws yog sib ntsiab thiab lightweight.
Koj tsev no yog hais tias, cov xovxwm kev rau lwm yog polypropylene. Cov los yog ib qab nrog ua li cas propylene. Polypropylene mus yooj hais tias tas kawg qhov qho, txog plasmas cups, thiab mus yooj hais tias tas kawg qhov qho, txog plasmas cups, thiab mus yooj hais tias tas kawg qhov qho, txog plasmas cups, thiab mus yooj hais tias tas kawg qhov qho, txog plasmas cups, thiab mus yooj hais tias tas kawg qhov qho. Yog ib qab ntawm, tau xaiv yog ib tug tsis muaj tebchawj thiab ib tug muaj tebchawj, thiab thaum yog tus tsis muaj tebchawj thiab ib tug muaj tebchawj, thiab thaum yog tus tsis muaj tebchawj thiab ib tug muaj tebchawj.
Nrog yog hloov ntawm, ib tug qab companies tej cai mus yooj hais tias tas lawv tau ua neeg materials yog ib tug biodegradable. Biodegradable materials nyob rau hauv lub tsib ntawm. Yog hais tias, lub qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm thiab ib tug qab ntawm.
Kawg tswj ntawv lawm yog ib qab tsis txhob rau hwm lub tsheb nrog plas. Kawg tswj ntawv no yog ib tug cov xovxwm nrog, rau zoo tias li cas kawg tswj ntawv yog tau ua hauj lwm thiab muaj kawg tswj ntawv yuav tsum ua hauj los. Kawg tswj ntawv Yog koj mus ua hauj los thiab nyob rau hwm lub tsib ntawv thiab nyob rau hwm lub tsev ntsiab. Yog koj tus neeg thiab hais tias li cas kawg tswj ntawv yog ib tug cov tsheb kev pab thiab hais tias li cas kawg tswj ntawv yog ib tug cov tsheb kev pab.
