Hydroxyethylethylenediamine muaj kev cia siab dav hauv kev lag luam

Cov teb siv: Hydroxyethylethylenediamine siv dav hauv cov tshuaj pleev ib ce, tshuaj, tshuaj tua kab, yas thiab lwm yam teb. Nrog rau kev txhim kho ntawm ntau yam lag luam, nws qhov kev thov hauv khw tseem nce ntxiv.
Nqe lag luam: Raws li cov xwm txheej tshiab tshaj plaws ntawm kev lag luam, tus nqi ntawm hydroxyethylethylenediamine hloov pauv. Piv txwv li, tus nqi hauv Hubei thaum Lub Kaum Hli 2024 yog 53,000 yuan / ton, thaum tus nqi hauv Shandong yog 21,300 yuan / ton. Qhov sib txawv ntawm tus nqi ntawm ntau thaj chaw thiab ntau hom yog loj heev.
Kev lag luam sib txawv: Nrog rau kev txhim kho tas mus li ntawm kev lag luam tshuaj lom neeg thoob ntiaj teb thiab kev txhim kho ntawm cov neeg lub neej, kev cia siab ntawm kev lag luam ntawm hydroxyethylethylenediamine yog dav heev. Yav tom ntej, nrog rau kev nthuav dav ntawm cov teb thov thiab kev loj hlob tas mus li ntawm kev thov kev lag luam, qhov ntsuas kev lag luam ntawm hydroxyethylethylenediamine yuav nthuav dav ntxiv.
Hauv kev xaus, ua ib qho khoom siv tseem ceeb ntawm cov tshuaj lom neeg organic, hydroxyethylethylenediamine siv dav hauv ntau qhov chaw thiab muaj kev cia siab rau kev ua lag luam. Tab sis tib lub sijhawm, nws tus nqi ua lag luam kuj hloov pauv, thiab nws yog qhov tsim nyog yuav tsum tau ua tib zoo saib xyuas cov qauv kev ua lag luam kom tsim cov tswv yim kev yuav khoom thiab kev muag khoom tsim nyog.

Kev siv ntawm Hydroxyethylethylenediamine

Hydroxyethylethylenediamine, tseem hu ua tus neeg sawv cev curing No. 1, yog ib qho khoom siv ntau yam nrog ntau yam kev siv, feem ntau suav nrog cov hauv qab no:

Cov khoom siv tshuaj lom neeg: Ua ib qho khoom siv tshuaj tseem ceeb thiab cov khoom siv tshuaj lom neeg txhua hnub, nws tuaj yeem siv los tsim cov tshuaj tiv thaiv xeb, cov tshuaj stabilizers, cov tshuaj vulcanization accelerators, thiab lwm yam.
Surfactant: Nws yog cov khoom siv tseem ceeb rau kev tsim cov cationic thiab zwitterionic imidazoline surfactants, thiab hom surfactant no suav txog feem ntau ntawm tag nrho cov peev xwm tsim khoom.
Tus neeg sawv cev epoxy resin curing: Ua tus neeg sawv cev zoo heev rau chav tsev kub uas tsis muaj tshuaj lom, nws yog siv nrog epoxy resin thiab siv dav rau kev sib txuas cov hlau thiab cov khoom tsis yog hlau, npaj cov txheej txheem epoxy tiv thaiv xeb, thiab lwm yam.
Lwm yam kev siv: Nws kuj tseem siv tau los tsim cov xim pleev, cov resins, roj hmab, cov neeg sawv cev flotation, tshuaj tua kab, thiab ua cov roj nplua nyeem ntxiv, cov hlau ion sealants, thiab lwm yam.
Hauv kev xaus, hydroxyethylethylenediamine muaj ntau yam kev siv hauv ntau qhov chaw vim nws cov khoom siv tshuaj lom neeg tshwj xeeb thiab kev ua tau zoo.
