1, It can be processed in advance by spraying its products with electric spray gun . Drying or natural drying, and then processing production, the share of waste to a minimum.
2, Can also be sprayed with electric spray gun after the product is formed.
3, can use oven drying, will obtain the most useful antibacterial anti-mildew effect, antibacterial layer and the bonding of the product is more solid, so the life of resistance to water washing more durable.
4, On the exterior of the product, it can be directly dried by spraying MEIBOSS paint anti-mildew agent or natural drying.
Type: Anti-mildew agent for paints
Use: Putty powder, diatomaceous earth, glue powder
Appearance: bright liquid
The water solubility is obtained by introducing ionic groups on the aromatic ring of thioxanthone (TX), such as the two types of WSP shown in formula (7-22).
TX-2S is a group of WSP in which the TX parent is substituted by the ionic group oxypropyl trimethyl ammonium methanesulfonate. The substitution position of the ionic group can be 2-, 3- or 4-position, which are respectively expressed as 2a, 2b, 2c. The ionic group substitution position in TX-3S may also have 2-, 3- or 4-position, which are represented as 3a, 3b, and 3c, respectively. Both Fou as sier [461 and Allen(+) found that in the TX-2S and TX-3S WSPs, the position of the ionic substituent directly affects the initiation efficiency. The system studied by Fou as sier is acrylamide/methyldiethanolamine (MDEA) /TX-2S (or TX-3S), the order of photo-initiated polymerization rate Rr is 2b>2c>2a and 3b>3c>3a, that is, for these two groups of WSPs, they are all 3-position honeywell specialty wax \substituted initiators The activity of the 2-position substitution is the highest. The system studied by Allen et al. is HEMA/methyldiethylamine/TX-2S (or TX-3S). It is believed that the 4-position substitution photoinitiator has the highest activity. Position substitution has the lowest activity.
For 3a, after monomethyl substitution or polymethyl substitution at the 1-, 3-, and 4-positions [Formula (7-23)], the polymerization-initiating activity is significantly increased , where 4-methyl The initiation activity of 3a and 1,3,4-trimethylation 3a is the highest, and the photoinitiation activity of the latter is almost twice that of unsubstituted 3a.
