Isticmaalka
2,4,6-Trimethylbenzoyldiphenylphosphine oxide isinta badan waxaa loo isticmaalaa khad daabacan oo shaashad ah, khad daabacan oo lithographic ah, khad daabacan oo flexographic ah, iyo dahaarka alwaaxa. TPO si buuxda ayaa loogu daaweyn karaa dusha sare ee cad iyo kuwa sare ee titanium dioxide. Si ballaaran ayaa loogu isticmaalaa dahaadh kala duwan, sababtoo ah waxqabadka nuugista ee aadka u fiican, waxay si gaar ah ugu habboon tahay khad daabacan oo shaashad ah, daabacaad fidsan, khad daabacan oo flexographic ah, iyo dahaarka alwaaxa. Dahaadhku ma jaalle noqdo, saameynta polymerization-ka kadib waa yar tahay, mana jirto wax haraag ah. Waxa kale oo loo isticmaali karaa dahaadh hufan, gaar ahaan ku habboon alaabada leh ur yar. Marka kaligaa loo isticmaalo polyester-yada aan buuxin ee ay ku jiraan styrene, waxay leedahay hufnaan bilow sare ah. Nidaamyada acrylic ester, gaar ahaan nidaamyada midabka leh, badanaa waxay u baahan yihiin in lagu isticmaalo iyadoo lagu darayo amines ama acrylamides, oo lagu daro photoinitiators kale si loo gaaro bogsiin dhammaystiran oo nidaamka ah. Waxay si gaar ah ugu habboon yihiin daaweynta jaallaha hooseeya, nidaamyada cad, iyo lakabyada filimka qaro weyn. Isku-darka photoinitiator TPO iyo MOB240 ama CBP393 waxay hagaajin karaan hufnaanta bogsashada. Waa dareeraha ugu fiican ee soo saarista dhirta hydrocarbon-ka udgoonka leh ee batroolka waxaana sidoo kale loo isticmaalaa sidii reagent formylation ee cilmiga kiimikada fiican.
Waa dareeraha ugu fiican ee soo saarista dhirta saliidda leh ee leh caraf udgoon; Xal isku dhafan oo ah N-formylmorpholine iyo morpholine (1:1) waa dareeraha soo saarista ee cutubka ketone methyl ethyl. Waxa kale oo loo isticmaalaa sidii fal-celin qaab-dhismeed oo ku saabsan kiimikada fiican. Inta badan waxaa loo isticmaalaa khad daabacaadda shaashadda, khad daabacaadda planographic, khad daabacaadda flexographic, dahaarka alwaaxa, dahaarka daaweynta UV, khad daabacaadda, dhejisyada daaweynta UV, dahaarka fiber-ka indhaha, iwm.
