Kagwiritsidwe Ntchito
Photoinitiator TPO ndi photoinitiator yothandiza kwambiri ya free radical (1) yomwe imayamwa nthawi yayitali. Chifukwa cha kuchuluka kwake kwakukulu kwa kuyamwa, nsonga yake yoyamwa ndi 350-400nm ndipo imayamwa nthawi zonse mpaka pafupifupi 420nm. Nsonga yake yoyamwa ndi yayitali kuposa ya oyambitsa wamba. Pambuyo powunikira, ma free radical awiri, benzoyl ndi phosphoryl, amatha kupangidwa, onse awiri angayambitse polymerization. Chifukwa chake, liwiro la photocuring ndi lachangu. Lilinso ndi mphamvu yowala ndipo ndi yoyenera kuuma kwambiri kwa filimu yokhuthala komanso mawonekedwe a utoto wosasintha. Ili ndi kusinthasintha kochepa ndipo ndi yoyenera machitidwe okhala ndi madzi.
Amagwiritsidwa ntchito kwambiri m'makina oyera ndipo amatha kugwiritsidwa ntchito pa zokutira zochiritsira za UV, inki zosindikizira, zomatira zochiritsira za UV, zokutira za ulusi wa kuwala, zotsutsa kuwala, mbale zosindikizira za photopolymer, ma resins a stereolithography, zinthu zophatikizika, zipangizo zodzaza mano, ndi zina zotero.
Monga choyambitsa kuwala, chimagwiritsidwa ntchito makamaka mu inki zosindikizira pazenera, inki zosindikizira za lithographic, inki zosindikizira za flexographic, ndi zophimba zamatabwa. TPO imatha kuchiritsidwa kwathunthu pamalo oyera kapena okhala ndi utoto wa titaniyamu woipa kwambiri. Imagwiritsidwa ntchito kwambiri mu zophimba zosiyanasiyana. Chifukwa cha mphamvu zake zabwino zoyamwitsa, ndi yoyenera kwambiri pa inki zosindikizira pazenera, zosindikizira za lithographic, inki zosindikizira za flexographic, ndi zophimba zamatabwa. Chophimbacho sichisanduka chachikasu, chimakhala ndi zotsatira zochepa za post-polymerization, ndipo sichisiya zotsalira. Chingagwiritsidwenso ntchito mu zophimba zowonekera, makamaka zoyenera zinthu zomwe zimafuna fungo lochepa. Chikagwiritsidwa ntchito chokha mu ma polyester osakhuta okhala ndi machitidwe a styrene, chimakhala ndi mphamvu yayikulu yoyambira. Pa machitidwe a acrylate, makamaka machitidwe amitundu, nthawi zambiri amafunika kugwiritsidwa ntchito limodzi ndi amines kapena acrylamides. Nthawi yomweyo, chimaphatikizidwa ndi ma photoinitiators ena kuti akwaniritse kuchira kwathunthu kwa dongosololi. Ndikoyenera kwambiri kuchiritsa machitidwe oyera, oyera komanso zigawo zokhuthala za filimu. Pamene photoinitiator TPO ikugwiritsidwa ntchito pamodzi ndi MOB 240 kapena CBP 393, mphamvu yochiritsa imatha kuwonjezeka. Ndi chosungunulira chabwino kwambiri chochotsera mafuta a petroleum aromatic hydrocarbon units ndipo chimagwiritsidwanso ntchito ngati formylation reagent m'munda wa mankhwala abwino.
Kulongedza ndi Kutumiza
20KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
