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.
Tsis tas li ntawd, 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.
Ib yam li ntawd, cov yas ua los ntawm cov menyuam yaus yog dab tsi? 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.
Nyob rau hauv no hais txog, qhov twg yog plastics ua?
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.
Puas yog yas ua los ntawm cov roj?
Yas yog ua los ntawm cov roj . Roj yog cov khoom siv uas muaj cov pa roj carbon ntau, thiab cov yas yog cov pa roj carbon ntau. Lawv yog cov molecules loj hu ua polymers, uas yog tsim los ntawm rov qab units ntawm luv luv carbon-muaj cov tebchaw hu ua monomers. Cov yas tau hloov pauv lub ntiaj teb.

Muaj pes tsawg kauj ruam nyob rau hauv xya kauj ruam txhim kho?
Xya kauj ruam
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?
