TPO photoinitiator, kwaziwa njengeInombolo ye-CAS 75980-60-8, yikhompawundi eguquguqukayo esetyenziswa ngokubanzi kumashishini ahlukeneyo.Njengoko igama libonisa, le nto isebenza njenge-photoinitiator, iqala kwaye ikhawulezise ukusabela kweefotochemical ngexesha lenkqubo yokunyanga izinto ze-UV-sensitive.
Umba ophambili ekumiseleni ukusebenza kakuhle kweTPO photoinitiatorbubude bayo.Iwavelength ibhekisa kumgama phakathi kwamanqaku amabini alandelelanayo amaza, kwaye idlala indima ebalulekileyo kunxibelelwano phakathiTPO photoinitiatorkunye nomthombo wokukhanya kwe-UV.
Ubude bamaza beI-TPO photoinitiatorsngokuqhelekileyo iwela ngaphakathi kwe-ultraviolet spectrum, ngokukodwa kuluhlu lwe-UVA lwe-315-400 nanometers (nm).Olu luhlu lwe-wavelength lukhethelwe ukukwazi ukwenza ngokusebenzayo lusebenze kwaye luqalise inkqubo yokunyanga.Ukukhethwa kwe-wavelength kuxhomekeke kwisicelo esithile kunye nezinto ezinyangwayo.
I-TPO photoinitiatorsukufunxa amandla okukhanya kubude obuchaziweyo.Xa evezwe kwimitha ye-UV kuluhlu olufanelekileyo lwamaza,TPO photoinitiatoriimolekyuli zingena kwinkqubo ye-photoexcitation.Oku kuthetha ukuba bafunxa iifotoni ekukhanyeni kwe-ultraviolet kwaye emva koko bakhulule amandla afunliweyo njengeentlobo ezisebenzayo ezifana neeradicals zamahhala okanye amazwe avuyayo.
I-TPO photoinitiatorsdala iintlobo ezisebenzayo ezithi emva koko ziqalise kwaye zisasaze iziphumo zokunyanga imathiriyeli ebuthathaka kwi-UV.Ezi mpendulo zibangela ukuba imathiriyeli idibanise ikhonkco, okanye i-polymerize, iyenze yomelele ngakumbi, izinze, kwaye ilungele usetyenziso olwahlukeneyo.
Kuyaphawuleka ukuba iifotonitiators ezahlukeneyo zineendlela ezithile zokufunxa amaza ngenxa yezakhiwo zazo zeemolekyuli ezizodwa.Ke ngoko, ukwazi ngokuthe ngqo uluhlu lwamaza amazaTPO photoinitiator(Inombolo ye-CAS 75980-60-8)kubaluleke kakhulu ekufumaneni iziphumo ezizezona zonyango.
Ukuququmbela,TPO photoinitiator(Inombolo ye-CAS 75980-60-8)iye yaba yinto ebalulekileyo kumashishini amaninzi ngenxa yokukwazi ukuqalisa kunye nokukhawulezisa inkqubo yokunyanga izinto ezibuthathaka kwi-UV.Ubude bayo buwela ngaphakathi koluhlu lwe-UVA 315-400 nm kwaye lunokusebenza ngokufanelekileyo kwaye lubangele ukusabela kokunyanga.NgokusebenzisaI-TPO photoinitiatorskubude obufanelekileyo, abavelisi banokuphucula inkqubo yokunyanga kwaye baphucule umgangatho kunye nokusebenza kweemveliso zabo ezinyangwa yi-UV.
