Daim ntawv Diethylhydroxylamine:

Cov khoom ntshiab ntawm diethylhydroxylamine (DEHA) yog cov kua tsis muaj xim pob tshab, thaum cov khoom lag luam yog cov kua daj daj me me. Thaum khaws cia, nws cov xim yuav maj mam hloov daj raws sijhawm, tshwj xeeb tshaj yog thaum raug tshav ntuj ncaj qha lossis cua, qhov xim hloov pauv yuav sai dua. Tsis tas li ntawd, thaum cov kua raug co hnyav, nws yuav ua rau turbid ib ntus, tab sis nws yuav meej tom qab ob peb teev.

Diethylhydroxylamine (DEHA) muaj ntau yam kev siv, feem ntau suav nrog cov hauv qab no:

1. Tshuaj tiv thaiv:
DEHA yog ib qho tshuaj inhibitor zoo heev, siv dav hauv kev tsim khoom, khaws cia thiab polymerization ntawm conjugated olefins xws li styrene, divinylbenzene, butadiene, thiab lwm yam, nrog rau cov nyhuv inhibitory siab thiab tsis cuam tshuam los ntawm kev hloov pauv kub.

2. Tshuaj tua kab mob thiab tshuaj antioxidant:
Hauv cov tshuaj tiv thaiv polymerization, DEHA tuaj yeem siv ua tus terminator zoo heev los nres lossis qeeb qeeb qhov tshuaj tiv thaiv thiab tswj cov khoom ntawm cov polymer. Tib lub sijhawm, nws kuj tseem siv tau ua antioxidant los txuas lub neej txee ntawm cov organic compounds xws li olefin monomers thiab polyolefins.

3. Cov tshuaj tiv thaiv pa phem photochemical:
DEHA muaj peev xwm tshem tawm cov free radicals thiab tswj kev tsim cov photochemical smog. Tsuas yog me ntsis tshuaj tsuag rau hauv huab cua thiaj li ua tiav qhov txiaj ntsig.

4. Cov khoom ruaj khov thiab cov khoom nruab nrab:
Hauv kev lag luam thaij duab, DEHA siv ua tus tswj xim thiab tus tswj xim rau cov tshuaj emulsions thaij duab, cov tshuaj emulsions uas rhiab heev, thiab kev thaij duab xim. Tsis tas li ntawd xwb, nws tseem yog ib qho tseem ceeb hauv kev tsim cov organic thiab koom nrog kev tsim ntau yam xim.
​

5. Cov tshuaj tua kab thiab cov khoom siv roj hmab ntxiv:
DEHA siv dav dav ua cov khoom siv raw ua rau cov tshuaj tua kab, cov tshuaj tua kab mob fungicides thiab cov tshuaj tua nroj. Nws kuj tseem siv ua cov khoom siv ntxiv rau hauv cov roj hmab kom txhim kho kev ua tau zoo ntawm cov khoom roj hmab.

6. Lub zog tshiab thiab cov teb tshuaj:
Hauv kev lag luam tshiab, DEHA yog siv los ua cov khoom siv rau kev npaj cov vaj huam sib luag hnub ci. Hauv kev lag luam tshuaj, nws yog ib qho khoom siv tseem ceeb rau kev tsim cov tshuaj.
