Kev Siv
2,4,6-Trimethylbenzoyldiphenylphosphine oxide isFeem ntau siv rau cov kua luam ntawv, cov kua luam ntawv lithographic, cov kua luam ntawv flexographic, thiab cov txheej ntoo. TPO tuaj yeem kho tau tag nrho rau ntawm ob qho tib si dawb thiab cov xim titanium dioxide siab. Siv dav hauv ntau yam txheej, vim nws qhov kev ua tau zoo heev, nws yog qhov tshwj xeeb tshaj yog rau cov kua luam ntawv, kev luam ntawv tiaj tus, cov kua luam ntawv flexographic, thiab cov txheej ntoo. Cov txheej tsis daj, qhov cuam tshuam tom qab polymerization qis, thiab tsis muaj cov khoom seem. Nws kuj tseem siv tau rau cov txheej pob tshab, tshwj xeeb tshaj yog haum rau cov khoom uas tsis muaj ntxhiab tsw. Thaum siv ib leeg hauv cov polyesters tsis muaj styrene, nws muaj kev pib ua haujlwm siab. Rau cov kab ke acrylic ester, tshwj xeeb tshaj yog cov kab ke xim, lawv feem ntau yuav tsum tau siv ua ke nrog amines lossis acrylamides, thiab sib xyaw nrog lwm cov photoinitiators kom ua tiav kev kho tag nrho ntawm lub kaw lus. Lawv yog qhov tshwj xeeb tshaj yog haum rau kev kho cov xim daj qis, cov kab ke dawb, thiab cov txheej zaj duab xis tuab. Kev sib xyaw ua ke ntawm photoinitiator TPO thiab MOB240 lossis CBP393 tuaj yeem txhim kho kev kho kom zoo. Nws yog cov kuab tshuaj zoo tshaj plaws rau cov nroj tsuag roj av uas muaj ntxhiab hydrocarbon thiab kuj siv los ua cov tshuaj formylation hauv kev ua cov tshuaj zoo.
Nws yog cov tshuaj zoo tshaj plaws rau kev rho tawm rau cov nroj tsuag roj av aromatic hydrocarbon; Cov tshuaj sib xyaw ntawm N-formylmorpholine thiab morpholine (1: 1) yog cov tshuaj rau kev rho tawm rau methyl ethyl ketone unit. Nws kuj tseem siv ua cov tshuaj formylation hauv kev ua cov tshuaj zoo. Feem ntau siv rau cov kua luam ntawv, kua luam ntawv planographic, kua luam ntawv flexographic, txheej ntoo, txheej UV curing, kua luam ntawv, cov nplaum UV curing, txheej fiber optical, thiab lwm yam.
