Isticmaalka
TPO-ga sawir-qaadaha waa sawir-qaadaha xorta ah ee aadka u hufan (1) kaas oo nuuga hirarka dheer. Sababtoo ah baaxadda nuugista ee aadka u ballaaran, heerka nuugista ee waxtarka leh waa 350-400nm wuxuuna si joogto ah u nuugaa ilaa qiyaastii 420nm. Heerka nuugistiisa wuxuu ka dheer yahay kan bilaabayaasha caadiga ah. Ka dib iftiiminta, laba xagjir oo xor ah, benzoyl iyo fosfooryl, ayaa la soo saari karaa, labaduba waxay bilaabi karaan polymerization. Sidaa darteed, xawaaraha sawir-qaadista waa mid degdeg ah. Waxa kale oo uu leeyahay saameyn sawir-qaadis ah wuxuuna ku habboon yahay daaweynta qoto dheer ee filimka qaro weyn iyo astaamaha dahaarka aan huruudka ahayn. Waxay leedahay isbeddel hoose waxayna ku habboon tahay nidaamyada biyaha ku salaysan.
Inta badan waxaa loo isticmaalaa nidaamyada cadcad waxaana lagu dabaqi karaa dahaarka UV-da la daaweyn karo, khad daabacan, dhejisyada UV-da la daaweyn karo, dahaarka fiber-ka indhaha, sawir-celiyeyaal, saxamada daabacaadda photopolymer, resins-ka stereolithography, walxaha isku dhafan, agabka buuxinta ilkaha, iwm.
Sida sawir-qaadaha, waxaa inta badan loo isticmaalaa khad daabacaad shaashadeed, khad daabacaad lithographic ah, khad daabacaad flexographic ah, iyo dahaarka alwaaxa. TPO si buuxda ayaa loogu daaweyn karaa dusha sare ee cad ama titanium dioxide ee aadka u midabaysan. Waxaa si weyn loogu isticmaalaa dahaadh kala duwan. Sababtoo ah sifooyinka nuugista ee aadka u fiican, waxay si gaar ah ugu habboon tahay khad daabacaad shaashadeed, daabacaadda lithographic, khad daabacaad flexographic ah, iyo dahaarka alwaaxa. Dahaarka ma noqdo huruud, wuxuu leeyahay saameyn hoose oo ka dambeysa polymerization ah, mana ka tago wax haraag ah. Waxa kale oo loo isticmaali karaa dahaadh hufan, gaar ahaan ku habboon alaabada leh ur yar. Marka keligeed loo isticmaalo polyester-yada aan dheregsanayn ee ka kooban nidaamyada styrene, waxay leedahay hufnaan bilow oo aad u sareysa. Nidaamyada acrylate, gaar ahaan nidaamyada midabka leh, badanaa waxay u baahan tahay in lagu isticmaalo iyadoo lagu darayo amines ama acrylamides. Isla mar ahaantaana, waxaa lagu daraa photoinitiators kale si loo gaaro bogsiin dhammaystiran oo nidaamka ah. Waxay si gaar ah ugu habboon tahay daaweynta nidaamyada huruud yar, kuwa cad iyo lakabyada filimka qaro weyn. Marka TPO-ga sawir-qaadaha la isticmaalo iyadoo lala kaashanayo MOB 240 ama CBP 393, waxtarka daaweynta ayaa la hagaajin karaa. Waa dareeraha ugu fiican ee soo saarista unugyada hydrocarbon-ka udgoonka leh ee batroolka waxaana sidoo kale loo isticmaalaa sidii reagent formylation ee ku saabsan kiimikada fiican.
