High performance superplasticizer powder can be used in cement-based or gypsum based materials, which can effectively improve the fluidity and mechanical strength of materials. It is widely used in construction engineering.

This product is used for oil and gas drilling, well digging and other projects; Synthetic detergent and soap industry, textile, printing and dyeing, papermaking, food, medicine, coating construction, daily chemicals, leather and other industries; It can be used as polymerization inhibitor in formaldehyde production and storage; In addition, it can be used in shipping, electronics, welding electrodes, Aquatic refrigeration and metal processing.

The main component of this product is aliphatic hydroxysulfonate, which is non-toxic, non combustible, non air entraining and chlorine free. It has no corrosion to reinforcement, very low sodium sulfate content, low alkali content, high water reduction rate, small dosage, high concrete strength and no crystallization in winter. It has better adaptability to cement varieties than general naphthalene products. It is a new generation of non naphthalene environmental protection high-efficiency water reducer. It can be used alone as water reducer, or combined with naphthalene and amino water reducer. It can be widely used in commercial concrete superplasticizer, retarding superplasticizer, composite pumping agent, etc.

Aminosulfonic acid superplasticizer (ASP) is a new type of superplasticizer developed after naphthalene, melamine and aliphatic superplasticizers. It overcomes the disadvantages of naphthalene and melamine superplasticizers, such as poor fluidity and large slump loss under low water cement ratio. It shows excellent characteristics in the following aspects: 1 ASP has strong water reducing and dispersing effect on cement paste: the experiment shows that under the same conditions, the content of ASP + 0.5% 25 is equivalent to the content of naphthalene system 0.75% 25, which can ensure that the concrete can still maintain good workability at low water cement ratio. Therefore, the aminosulfonic acid high-efficiency water reducer has higher water reducing rate than naphthalene system and melamine system, and the fluidity of cement paste is large Strong dispersion. 2. The slump loss of concrete can be almost reduced when ASP is mixed with high-efficiency naphthalene within 60 minutes, which shows that ASP can control the slump loss of concrete. 3. ASP has strong retarding effect on cement and concrete. 4. The effect of ASP on concrete reinforcement is obvious: the compressive strength is one of the most important mechanical properties of concrete. The experiment shows that ASP is better than other superplasticizers, has stronger water reducing effect on concrete and more obvious improvement of strength. In conclusion, aminosulfonic acid series superplasticizer has high water reducing rate, low dosage, small slump loss and more obvious improvement of strength. It is a superplasticizer with excellent performance.

Plant polyol is a raw material that can replace petroleum polyether polyol to produce polyurethane. Taking miscellaneous wood, moso bamboo powder, moso bamboo fiber and vegetable oil, such as soybean oil and castor oil, as the base materials, they are put into the reactor for a series of reactions to produce plant polyols.
