Txhawm rau ua cov yas, cov kws tshuaj thiab kws tshuaj lom neeg yuav tsum ua cov hauv qab no ntawm cov khoom lag luam:
- Npaj cov khoom siv raw thiab monomers.
- Ua cov tshuaj tiv thaiv polymerization.
- Txheej txheem cov polymers rau hauv qhov kawg polymer resins.
- Tsim cov khoom tiav.
Ua kom pom qhov no, cov yas tau piav qhia yooj yim li cas?
Cov yas yog ua los ntawm cov ntaub ntawv raw xws li roj av, roj lossis nroj tsuag, uas tau ua kom huv rau hauv ethane thiab propane. Ethane thiab propane tom qab ntawd raug kho nrog cua sov hauv cov txheej txheem hu ua "cracking" uas hloov lawv mus rau hauv ethylene thiab propylene. Cov ntaub ntawv no tau koom ua ke los tsim cov polymers sib txawv.
Dab tsi yog yas ua los ntawm cov menyuam yaus? Cov yas yog (feem ntau) hluavtaws (tib neeg- ua ) cov ntaub ntawv, ua los ntawm cov polymers, uas yog cov molecules ntev ua nyob ib puag ncig cov saw ntawm cov pa roj carbon, feem ntau nrog hydrogen, oxygen, leej faj, thiab nitrogen sau rau hauv qhov chaw.
Ib yam li ntawd, nws tau nug, yas yog dab tsi thiab nws tau ua li cas?
Yas yog ua los ntawm cov khoom siv ntuj tsim xws li cellulose, thee, roj nkev, ntsev thiab roj av los ntawm cov txheej txheem polymerization lossis polycondensation. Plastics tau muab los los ntawm natural, organic cov ntaub ntawv xws li cellulose, thee, natural gas, ntsev thiab, ntawm chav kawm, cov roj crude.
Cov yas ua nyob qhov twg?
Cov yas yog muab los ntawm cov ntaub ntawv uas muaj nyob rau hauv cov xwm, xws li natural gas, roj, thee, minerals thiab nroj tsuag. Thawj zaug yas tau ua los ntawm qhov-koj puas paub tias roj hmab los ntawm tsob ntoo roj hmab yog qhov tseeb yas ?

Cov kauj ruam hauv peb kauj ruam sau ntawv yog dab tsi?
Hauv cov ntsiab lus dav dav, txheej txheem sau ntawv muaj peb qhov tseem ceeb: sau ua ntej, sau, thiab sau ntawv tom qab. Peb qhov no tuaj yeem muab faib ua 5 kauj ruam ntxiv: (1) Kev Npaj; (2) Kev sib sau ua ke; (3) Composing / Drafting; (4) Kev hloov kho / kho; thiab (5) Pro ofreading
Thawj kauj ruam ntawm 7 kauj ruam txhim kho yog dab tsi?
Xya Kauj Ruam Nruam Txhim Kho Txheej Txheem Kauj Ruam 1: Txheeb xyuas lub tswv yim rau kev txhim kho. Kauj Ruam 2: Txhais qhov yuav ntsuas. Kauj ruam 3: Sau cov ntaub ntawv. Kauj ruam 4: Ua cov ntaub ntawv. Kauj Ruam 5: Txheeb xyuas cov ntaub ntawv thiab cov ntaub ntawv. Kauj Ruam 6: Qhia thiab siv cov ntaub ntawv. Kauj Ruam 7: Siv kev txhim kho
Kauj ruam 1 ntawm 7 kauj ruam txhim kho yog dab tsi?
