Taupānga

1. Kei te whakamahia te nuinga hei aukati polymerization, te aukati UV, te waikano takawaenga me te BHA antioxidant mo te whakahiato o nga hinu kai me nga mea whakapaipai.
2. Ka whakamahia hei aukati polymerization, te aukati UV, te waikano takawaenga me te antioxidant BHA (3-tert-butyl-4-hydroxyanisole) mo te whakahiato o nga hinu kai me nga mea whakapaipai.
3. Wairewa. Ka whakamahia hei aukati mo te monomer kirihou vinyl; Uv aukati; Ko nga waikano takawaenga me te antioxidant BHA (3-tert-butyl-4-hydroxyanisole) i whakamahia i roto i te whakahiato o nga hinu kai me nga mea whakapaipai. Ko tana painga nui ko te monomer i muri i te taapiri i te MEHQ me etahi atu monomers kaore e hiahiatia kia tangohia i te wa e kapehia ana, ka taea te kopolymerization tika ternary, ka taea hoki te whakamahi hei antioxidant, antioxidant me etahi atu.
