Daim ntawv thov

1.Nws yog siv los ua polymerization inhibitor, UV inhibitor, dye intermediate thiab antioxidant BHA rau synthesis ntawm edible roj thiab tshuaj pleev ib ce.
2. Nws yog siv los ua polymerization inhibitor, UV inhibitor, dye intermediate thiab antioxidant BHA (3-tert-butyl-4-hydroxyanisole) rau synthesis ntawm cov khoom noj roj thiab tshuaj pleev ib ce.
3. Cov kuab tshuaj. Siv los ua ib qho inhibitor ntawm yas yas monomer; Uv inhibitor; Dye intermediates thiab antioxidant BHA (3-tert-butyl-4-hydroxyanisole) siv nyob rau hauv synthesis ntawm edible roj thiab tshuaj pleev ib ce. Nws qhov txiaj ntsig loj tshaj plaws yog tias cov monomer tom qab ntxiv MEHQ thiab lwm yam monomers tsis tas yuav raug tshem tawm thaum copolymerizing, tuaj yeem ua ternary ncaj qha copolymerization, kuj tuaj yeem siv los ua antioxidant, antioxidant thiab lwm yam.
