Iyini indima yama-catalysts ekuphenduleni kwe-hydroxyethyl acrylate?
Ukuze ukusabela kokuzipholima kwenzeke, izinga lokutjhisa elifaneleko liyatlhogeka kokuthoma. Ngokuvamileko, izinga lokutjhisa lokuzipholimela kwe-hydroxyethyl acrylate FANELE iphakathi kwama-30°C kanye nama-60°C. Nangabe amazinga womtjhiso aphasi khulu, ukusabela kuzokuba buthakathaka khulu nofana kungenzeki. Nangabe izinga lokutjhisa liphezulu khulu, ukusabela kungaba nobudlova khulu, okwenza bona kube budisi ukulawula ikambiso yokusabela begodu kubangele imikhiqizo engazinzileko. Ngalokho-ke, ukulawula amazinga womtjhiso kuqakathekile khulu! Ngaphezu kwamazinga womtjhiso, ukukhanya nakho kuyinto eqakathekileko. I-Hydroxyethyl acrylate iphendula khulu ekukhanyeni kwe-ultraviolet (UV), begodu ukukhanya kwe-UV kungakhuthaza ukuhlukaniswa kwamabhondi wayo amabili, ngaleyindlela kuthome ukusabela kwe-polymerization. Ngaphasi kokukhanya kwe-UV, ukuzijamela kwe-hydroxyethyl acrylate hea kuzokurhaba khulu. Nasisebenzisa isibane se-UV nofana sisibeke elangeni, sizokwenza bona sibe yi-polymer msinyana. Cabanga nje, ngaphasi kokukhanya kwelanga, amamolekhyuli la afana nokugida, ahlangana msinyana enze izinto ezitjha. Ngaphezu kwamazinga womtjhiso nokukhanya, ukukhetha i-catalyst nakho kuthinta izinga nomphumela wokusabela kokuzipholima. Sizokufaka amanye ama-peroxide catalysts, afana ne-hydrogen peroxide, nofana amakhompawundi we-azo afana ne-azobisisobutyronitrile (AIBN). Ama-catalyst la angehlisa kuhle izinga lokutjhisa lokuthoma lokuziphendulela, okwenza bona kuragele phambili kuhle ngitjho nasemazingeni womtjhiso aphasi. Kwamambala zisebenza njengezirhabisi! Ngaphandle kwesikhuthazi, ukusabela kungaba buthakathaka khulu nofana kungenzeki. Ngalokho-ke, indima ye-catalyst ekuphenduleni kokuzipholimera angeze yatjhiywa.
