Photoinitiator TPO upfu 98% CAS 75980-60-8 TPOP
Photoinitiator TPO upfu 98%CAS 75980-60-8TPOP
TPO inonyatso shanda mahara radical (1), yakakwirira inoshanda yekuona kunyudzwa kweiyo initiator murefu wavelength renji. Nekuda kwekuti ine huwandu hwakasiyana hwekunyura, iyo peak yekunyura i350-400nm, yakakonzerwa nekutorwa kweinenge 420nm, kunyura kwayo peak kupfuura yakajairwa initiator yakarebesa, mwenje unogona kugadzira benzoyl uye phosphoryl mbiri.
free radimacals anogona kukonzera polymerization, saka mwenje wekuporesa kukurumidza, ine zvakare ine photobleaching, yakakodzera kune gobvu firimu kupfekedzwa uye yakadzika kurapa yero maitiro ane yakaderera kuvhurika, yemvura. Ichi chigadzirwa chinoshandiswa kune chena sisitimu, inogona kushandiswa UV kurapa machira, kudhinda ingi, zvinonamira, UV kurapa optical fiber coating, photoresist, photopolymerization ndiro, stereo lithographic resin, composite zvinhu, mazino kuzadza etc.. Kushandiswa kwechigadzirwa ichi inofanira kubva pamigumisiro chaiyo yekuedza, zvinokurudzirwa kuwedzera huwandu hwe 0.5-4% w / w. Inogona kusimbiswa zvachose pamusoro pechena kana yakakwirira titanium dioxide pigment. Iyo yekupfekedza haichinji, mhedzisiro yepolymerization yakaderera, uye hapana chakasara. Inogona zvakare kushandiswa kune akajeka machira, kunyanya kune yakaderera kunhuwa zvigadzirwa. Inoshandiswa mu polyester isina unsaturated ine styrene system, ine hukuru hwepamusoro. Iyo acrylate system, kunyanya iyo ine mavara system, kazhinji inoda kushandira pamwe neamine kana acrylamide, uye imwe light initiator compound, kurapa kuti iwane yakakwana yekurapa system inonyanya kukodzera kune yakaderera yero, chena uye gobvu firimu. Ingi yekutsikisa skrini, inki yekudhinda yeoffset. Yakakurudzirwa kuwedzera huwandu hwe0.5-3.0% (yemavara system), 0.3-2.0% (transparent system.
