Product Overview

Azobisisobutyronitrile (AIBN) yog ib hom azo- hom dawb radical pib. Thaum rhuab, nws decomposes los tsim cov dawb radicals thiab tso tawm cov roj nitrogen, yog li pib cov tshuaj dawb radical polymerization. Nws tus cwj pwm decomposition yog ruaj khov thiab yooj yim los tswj, ua rau nws dav siv nyob rau hauv lub polymer, resin, thiab zoo tshuaj industries. Feem ntau rhuab ntawm 60-80 degree, AIBN tau dhau los ua homolytic cleavage ntawm azo daim ntawv cog lus nrog kev sib tw thiab kev kwv yees cov tshuaj tiv thaiv, ua rau nws tsim nyog rau feem ntau cov tshuab polymerization.

Vim nws cov qauv molecular symmetrical thiab ib qho radical tiam txoj hauv kev, AIBN zoo txo cov kev xav sab nraud thiab ua kom muaj kev tswj xyuas qhov hnyav ntawm molecular faib. Hauv kev tsim khoom, feem ntau yog siv hauv acrylic resins, styrene polymerization, acrylonitrile ntau lawm, hluavtaws roj hmab, thiab ntau yam khoom siv polymer.

Product Description

Khoom nta

AIBN yog ib qho azo compound uas decomposes thaum cua sov los tsim cov dawb radicals thiab nitrogen gas. Qhov kub decomposition feem ntau yog 60-80 degree, nrog rau qhov ruaj khov thiab tswj tau cov tshuaj tiv thaiv.

Tswj tus cwj pwm decomposition
ruaj khov radical tiam efficiency
Tsawg sab tshua
Cov txheej txheem dav dav adaptability

Khoom zoo

Piv nrog rau cov neeg pib peroxide, AIBN muaj ntau qhov zoo ntawm kev siv hauv kev lag luam:

Cov txheej txheem tshuaj tiv thaiv me me thiab tswj tau ntau dua, txhim kho kev nyab xeeb
Ntau yam radical tiam
Kev tswj qhov hnyav molecular zoo dua
Ntxuav lub cev nrog nitrogen ua lub ntsiab los ntawm - khoom
Haum rau kev daws, bulk, thiab emulsion polymerization

Cov txiaj ntsig ntawm cov neeg yuav khoom

Kev siv siab -purity AIBN pab cov neeg siv khoom kom ua tiav kev ua tau zoo dua qub:

Ntau dua polymerization efficiency thiab luv dua cov tshuaj tiv thaiv kab mob
Txhim kho qhov hnyav molecular faib sib xws
Txo cov tshuaj tiv thaiv sab nraud thiab tsim cov gel
Kev ua tau zoo kawg ntawm cov khoom lag luam (ntshiab, lub zog, ruaj khov)
Txo cov txheej txheem hloov thiab cov nqi hluav taws xob

Cov ntaub ntawv pov thawj lossis Case Studies

Cov ntawv thov kev lag luam hauv cov tshuab acrylic thiab styrene qhia tias kev siv AIBN tuaj yeem ua rau:

Txhim kho txheej txheem stability
Txo batch - mus rau -batch variation
Narrower molecular hnyav tis
Tsawg impurity thiab los ntawm - cov khoom tsim

Txij li thaum nitrogen yog cov khoom tseem ceeb decomposition, cov seem seem tsawg, ua rau nws haum rau siab -purity resins thiab cov khoom siv.

Hu rau Action

Yog tias koj tab tom nrhiav ib tus neeg muab kev ntseeg siab ntawm siab -purity Azobisisobutyronitrile (AIBN), peb tuaj yeem muab cov kev daws teeb meem zoo ib yam, hloov pauv hloov pauv, thiab cov khoom lag luam thoob ntiaj teb ruaj khov los pab txhawb koj cov khoom siv polymer nrog kev txhim kho thiab kev ua haujlwm ntawm cov khoom.
