Kushandiswa
Photoinitiator TPO iphotoinitiator inoshanda zvakanyanya yefree radical (1) yerudzi rwephotoinitiator inonyudza munzvimbo refu yewavelength. Nekuda kwenzvimbo yayo yakakura yekunyudza, peak yayo inoshanda ye350-400nm uye inogara ichinyudza kusvika pa420nm. Peak yayo yekunyudza yakareba kupfuura iyo yeinotanga kushandiswa. Mushure mekuvhenekerwa, mafree radicals maviri, benzoyl nephosphoryl, anogona kugadzirwa, ese ari maviri anogona kutanga polymerization. Nokudaro, kumhanya kwephotocuring kunokurumidza. Inewo mhedzisiro yephotobleaching uye yakakodzera ganda rakakora uye hunhu hweisina yero. Ine volatility yakaderera uye yakakodzera masisitimu akavakirwa mumvura.
Inonyanya kushandiswa mumasystem machena uye inogona kushandiswa pakupenda zvinorapika neUV, inki dzekudhinda, zvinonamira zvinorapika neUV, zvinonamira nefiber ye optical, zvinonamira ne photoresists, mapurati ekudhinda e photopolymer, ma stereolithography resins, zvinhu zvakasanganiswa, zvinhu zvekuzadza mazino, nezvimwewo.
Semuchina wekugadzira mifananidzo, inonyanya kushandiswa mu inki dzekudhinda dzechidzitiro, inki dzekudhinda dze lithographic, inki dzekudhinda dze flexographic, uye matanda ekupenda. TPO inogona kurapwa zvachose panzvimbo chena kana dzine pigment yakawanda ye titanium dioxide. Inoshandiswa zvakanyanya mumhando dzakasiyana dzekupenda. Nekuda kwehunhu hwayo hwakanaka hwekunyudzwa, inonyanya kukodzera inki dzekudhinda dzechidzitiro, kudhinda kwe lithographic, inki dzekudhinda dze flexographic, uye matanda ekupenda. Kupenda hakushanduki yero, kune simba shoma mushure me polymerization, uye hakuna kusiya zvasara. Inogona zvakare kushandiswa mumavara akajeka, kunyanya akakodzera zvigadzirwa zvine kunhuhwirira kushoma. Kana ikashandiswa yoga mu polyester dzisina kuguta dzine styrene systems, ine simba guru rekutanga. Kune acrylate systems, kunyanya masisitimu ane mavara, inowanzo fanirwa kushandiswa pamwe chete ne amines kana acrylamides. Panguva imwe chete, inosanganiswa nedzimwe photoinitiators kuti iwane kupora kwakakwana kwesisitimu. Inonyanya kukodzera kupora masisitimu machena, machena uye zvidimbu zvefirimu gobvu. Kana photoinitiator TPO ikashandiswa pamwe chete neMOB 240 kana CBP 393, kushanda zvakanaka kwekupisa kunogona kuvandudzwa. Ndiyo solvent yakanakisa yekubvisa petroleum aromatic hydrocarbon units uye inoshandiswawo seformylation reagent mumunda wemakemikari akanaka.
Kurongedza uye Kutumira
20KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
