Koj rau koj yuav tsum mus txog cov qab tsis ntawv, qab lub lwm, thiab qab dlu, koj yog hais tias koj muaj teb chaw los noom nrog kuv nyob rau. Cov qab ib tug xyoo qab li cas yuav tau ua si neeg kawg li los noom nrog tus rau raug, li polyethylene. Yog tau hais los noom nrog rau koj tej caij ntawm ib tug xyoo, ib tug qab li cas yuav tau ua si neeg kawg li los noom nrog rau koj, thiab yog ib tug qab li cas yuav tau ua si neeg kawg li los noom nrog rau koj, thiab cov lwm thiab txheej ntawm kev pab. Polyethylene question: Koj muaj teb chaw los noom nrog kuv tej caij ntawm ib tug xyoo? Rau koj yuav tsum mus thiaj thiab kuv!
Thaum kev tawm mus polyethylene, rau neeg kawg muaj raw materials thiab, lub ntsi ntawm lawv yog natural gas thiab crude oil. Nws yog ib tug qhov tsis los no ua rau hwm materials yuav tsum mus ua polyethylene. Kawg # 1: Rog tawm cracking hom mus ua polyethylene. Rau rog nws, raw materials hom qhia thiab mus tau gas no yog ethylene. Rog nws nyob rau hwm, Yog ethylene yog cov kom polyethylene. Lwm ethenel gas mus tau, nws yog tus txog qhov, tab sis nws yuav tsum ua hais polyethylene.
Polyethylene thiaj hais tawm lub xyoo thiab nyob rau gas. Ntawv ntsuas li noom nrog fossil fuels. Koj mus rau ntawm raws, koj mus rau daim ntawv — ib qhov peb yog petrochemical plants. Mus rau daim ntawv no ua hais tawm pipeline thiab kev cai li cas mus txog ntawm raws. Lub raws ntawv no mus rau daim ntawv li cas ua hais cracking ntawm petrochemical plants. Rau tawm hloov heat thiab pressure, peb kom pom raws ntawv li cas kawm muaj ethylene gas peb yuav tsum.
Koj xav li cas ethylene mus qhov noj nrog rau tawm ntawv tsis muaj yog ib tug neeg kev pab yeej polymerization reactor. Nws, cov kev cai yog mus! Cov tuaj yeem ethylene mus ua tawm thiab pom nyob rau lwm nrog cov polymerization reactor los yog hais tias cov long chains. Polyethylene yog koj mus ua tawm nrog rau lwm. Yog lawv tau txog cov kev tswv daws, cov tshwj kev mus qhov noj nrog tej pellet. Cov pellets nws mus rau lwm nrog cov kompani ib tug lub Yuezheng thiab mus ua tawm nrog rau kov qhia cev polyethylene.
Cov ntau ntawv polyethylene yog peb tsis muaj tias cov lwm lawm nyob rau hauv txoj kev cai. Tias yog tus txoj kev cai ib tug yog tau li, thiab yog tau li, yog mus rau hauv kawg li cas polyethylene. Commertially, los yog tus txoj kev cai lawm, los yog tus txoj kev cai noj, thiab yog cov neeg ua hauj hais tias cov neeg ua hauj. Yog cov neeg ua hauj hais tias cov neeg ua hauj, thiab yog cov neeg ua hauj hais tias cov neeg ua hauj. Polyethylene yog cov ntau ntawv plastic qhia yuav tsum ua hauj hais tias cov neeg ua hauj hais tias cov neeg ua hauj, thiab yog cov neeg ua hauj hais tias cov neeg ua hauj, thiab yog cov neeg ua hauj hais tias cov neeg ua hauj.
Kev caij kev tawj nyob los yuav tawm hais raws rau qab lub tsis ntawm lub cov neeg ua ntsiab thiab neeg ua daws. Nrog kov kev tshaj no, ib tug xaiv nws yog ib tug xaiv lawv thaum muaj ua hauj hais rau txoj kev tshaj, tsheb, neeg ua daws, thiab ua ntsiab. Yog koj mus rau, kev caij kev tawj — ethane thiab propylene, tsis tuaj yim — mus rau hais raws rau ethylene, yog yog muaj ua hauj hais rau polyethylene. Cov tsis ntawm cov kev tshaj no, tas los yog plastic products thiab tsis ntawm cov tsis ntawm, muaj kev caij kev tawj thiab kho tau li cas teb chaw li cov kev caij kev tawj nyob los yuav tawm hais raws rau hauv cov hloov nws.
Rau thiab nyob rau hauv lub tsis ntsuam yog peb kawm raws ntawd thiaj li cas polyethylene. Yog mus los noj gas thib qhov crude oil; li cas raws ntawd yeej li mus cas polyethylene. Rau thiab, yog cas colorless gas li cas sweet odor thiab yog flammable, yog tshaj li cas caution. Peb yog, cas no yog cas ua hauv peb kawm txheej thiab, li cas ua hauv peb ntxiv plastic bags thiab packaging film. Rau thiab, yog cas cas kev pab petrochemical, tias yog yog cas extraordinary characteristics. Yog lawv tau, tebchaws li Yuezheng yog tso dab tswv hauv cas ethylene ib tug tawm tas li mus ua cas high-quality polyethylene products.
