defoamer classification
polyether type defoamer types type more, main/primary has below/following types: defoamer, 也称消沫 agent, is in food processing process in reduce surface force, made foam generate or remove already generate foam food additives. 我国许 can use defoamer has emulsification silicon 油, high carbon alcohol acid ester composite/compounding material, poly oxygen ethylene poly oxygen propylene 季戊四 alcohol ether, poly oxygen ethylene poly oxygen alcohol amine ether, poly oxygen propylene ether and poly oxygen propylene poly oxygen ethylene ether, poly 二甲基 silicon oxygen and other 7 types.
most commonly used is poly 二甲基 silicon oxygen 烷, 也称二甲基 silicon 油. it surface can low, surface force relatively low, in water and generally in solvent understanding degree low active property high. it is silicon oxygen 键, is non property separation 子. and property solvent agent water hydrophilic and, and generally hydrophilic and property very small. it property low tool has chemical inert property, comparison stability property small. pure poly 二甲基 silicon oxygen 烷, dispersion difficult as is defoamer. can can is due to it and water has high interface force, 铺展系数 low, easy dispersion in foaming upper. therefore will silicon mixed 入SiO2 gas solvent 胶, formed composite/compounding material, will hydrophobic water rear SiO2 gas solvent mixed 入二甲基 silicon in, 经一定 temperature degree, time 处理, can made.
classification
defoamer large can separation type:一 type can remove already generate bubbles,如乙 alcohol and other;另一 type can made bubbles formed emulsification silicon and other. 我国许 can use defoamer has emulsification silicon 油, high carbon alcohol acid ester composite/compounding material, poly oxygen ethylene poly oxygen propylene 季戊四 alcohol ether, poly oxygen ethylene poly oxygen alcohol amine ether, poly oxygen propylene ether and poly oxygen propylene
RQ-X1 polyether modified silicon 油
结 combined polyether has machine silicon defoamer advantages, tool has 无毒无害, for types 无害, add amount less, is types high property ratio product.
按 function separation is:
1, resistant alkali defoamer
in high temperature strong/high alkali conditions lower can speed 消泡,持久抑泡. stability property good, use amount less, efficiency high, 不漂油; widely used in 造纸蒸煮黑 liquid 处理, textile industry in strong/high alkali type agent, strong/high alkali conditions lower agent and its it high temperature strong/high alkali water versus system 消泡.
2, resistant acid defoamer
由脂肪 acid ester and 脂肪酰 amine and other material formed, widely used in wet method acid, titanium ** production, acid production and other strong/high acid system.
3, high viscous property foam defoamer
本 product is for made liquid, chemical 选矿, specialty chemical reaction generate foam, its viscosity large, foam fine 密, remove difficult degree large and other features made formed types high composite/compounding type defoamer.
4, coating material defoamer
含 has multiple excellent 质 消泡 formed separation, suitable 面广, it especially suitable for remove 苯丙胶乳, 乙丙胶乳, pure 丙胶乳, acid ethylene and other system foam.
5, defoamer
can has control 纸浆, foam and improve/increase quality. used for 造纸抄造 system 消泡, can used for 造纸污 water 处理, anti liquid, system 消泡.
6, water 泥砂浆 defoamer
can has control water 泥砂浆 system inner foam generate, make mixed 凝土构 parts more add light 亮.
7, industrial defoamer
can has control industrial process in inner foam generate, improve/increase production efficiency.
8, use defoamer
can has control agent generate foam.
9, cationic system defoamer
can has control has cationic system foam generate, widely used in 造纸抄造 use cationic 离子松香胶, cationic type agent, can used for 造纸污 water 处理, anti liquid, system 消泡.
10, high 效发酵 defoamer
克服 普通 type has machine silicon defoamer high temperature resistance property 差, time short disadvantages; for in 发酵罐 in upper rise foam can polyether fast speed remove, meanwhile product has polyether method ratio time advantages.
11, water defoamer
has machine silicon defoamer for water property foaming system tool has very strong/high 消泡, function add amount small use cost comparison low, is water property system relatively defoamer
