Kev yaj dej tau

Tetraethylenepentamine (TEPA) yog ib yam tshuaj lom neeg uas siv tau ntau yam thiab siv tau rau ntau qhov chaw lag luam. Cov hauv qab no yog cov kev siv tseem ceeb ntawm tetraethylene pentamine:

1. Cov khoom siv hluavtaws thiab cov yas
Polyamide Resin: Tetraethylenepentamine yog siv los ua cov polyamide resin, ib qho thermoplastic uas muaj zog thiab tiv taus cua sov.
Cation Exchange Resin: Siv los tsim cov cation exchange resins, uas ua lub luag haujlwm tseem ceeb hauv kev kho dej thiab cov txheej txheem ntxuav.
2. Cov Khoom Ntxiv
Cov roj ntxiv rau lubricating: Txhim kho kev ua haujlwm ntawm cov roj lubricating thiab txo qhov kev sib txhuam thiab kev hnav.
Cov khoom siv ntxiv rau roj: Txhim kho kev ua haujlwm ntawm kev sib xyaw thiab kev ua haujlwm ntawm roj.
3. Tus neeg sawv cev kho thiab tus ua kom nrawm dua
Tus Neeg Sawv Cev Epoxy Resin Curing: Siv los kho epoxy resin thiab txhim kho nws qhov nyuaj thiab tshuaj lom neeg tiv taus.
Cov roj hmab vulcanization accelerator: Ua kom cov txheej txheem vulcanization ntawm roj hmab sai dua thiab txhim kho qhov zoo thiab ruaj khov ntawm cov khoom roj hmab.

4. Cov tshuaj tiv thaiv uas muaj hlau ua rau cov tshuaj no ua haujlwm

Tetraethylenepentamine feem ntau siv ua lub hauv paus organic hauv kev tsim cov organic vim nws muaj ntau yam amino units thiab tuaj yeem tsim ntau yam kev sib koom tes. Nws cov amino unit tuaj yeem tsim ib qho complex nrog cov hlau ions thiab muaj peev xwm sib koom tes zoo thiab xaiv tau zoo. Nws yog siv dav hauv cov tshuaj catalytic hlau thiab muaj cov ntawv thov zoo hauv kev ntes thiab sib cais cov hlau ion.
5. Lwm yam kev siv
Anion pauv resin: Siv los tsim cov anion pauv resin rau kev kho dej thiab kev ntxuav.
Kev ntsuas complexometric: Siv rau kev ntsuas complexometric ntawm cov hlau xws li tooj liab, zinc thiab nickel siv txoj kev xaus tam sim no.
Cov tshuaj tiv thaiv Saponification: Koom nrog cov txheej txheem saponification ntawm cov tshuaj acidic.
Tus neeg sawv cev ntxuav thiab ziab roj: siv rau hauv cov txheej txheem ntxuav thiab ziab roj ntawm cov roj hmab hluavtaws thiab cov khoom siv.
