1. Ua cov ntaub ntawv
Vim tias tsis ntev los no muaj kev kub ntxhov cuam tshuam nrog Iran, cov nqi roj av thoob ntiaj teb tau nce siab. Polyester Resin yog ib qho tseem ceeb ntawm cov khoom siv petrochemical thiab cov khoom siv tseem ceeb rau FRP nplooj ntawv. Yog li ntawd, nws tus nqi yog qhov zoo sib xws nrog cov roj av, uas ua rau cov nqi txuas ntxiv mus rau FRP nplooj ntawv thoob plaws kev lag luam tsis ntev los no.
Raws li FRP nplooj ntawv chaw tsim khoom, peb kuj tau cia siab tias qhov kev hloov pauv no. Ua tsaug rau peb cov tswv yim raw cov ntaub ntawv khaws tseg, tam sim no peb muaj peev xwm tswj tau peb cov nqi qub yam tsis muaj kev nce ntxiv rau peb cov neeg koom tes.
Koj puas pom cov nqi sib xws hauv koj lub lag luam?Koj puas yuav khaws cov ntawv FRP rau koj cov phiaj xwm lub cev?
2.Txoj kev paub nthuav dav
Polyester resin yog cov khoom lag luam qis qis ntawm kev lag luam petrochemical, thiab nws cov nqi hloov pauv tau zoo sib xws nrog cov nqi roj av. Txoj kev xa khoom xa mus yog raws li hauv qab no: Cov Roj Crude: Cov khoom siv raw tshaj plaws. Naphtha: Ib yam khoom ntawm cov roj crude refining. PX (para-xylene) & Benzene: Muab los ntawm naphtha tawg lossis hloov kho. PTA (purified terephthalic acid) & Ethylene glycol (EG) / Neopentyl glycol (NPG): PTA yog tsim los ntawm oxidation ntawm PX. Ethylene glycol thiab neopentyl glycol kuj tseem yog los ntawm cov roj av derivatives (qee qhov neopentyl glycol kuj tuaj yeem npaj los ntawm txoj kev isobutyraldehyde, tab sis qhov chaw tseem cuam tshuam los ntawm cov nqi hluav taws xob). Polyester resin: Ua los ntawm cov tshuaj tiv thaiv polycondensation ntawm PTA, ethylene glycol, neopentyl glycol, thiab lwm yam.
