What are the different advantages of Powdered Potassium Silicate and Liquid Potassium Silicate?
From the essence of the product, Modulo (M): 2.4 ± 0.1 Powdered Potassium Silicate is a product obtained by drying and spraying liquid potassium silicate through advanced technology. Using internationally advanced spray drying technology, liquid potassium silicate is instantly atomized in a high-temperature hot air flow, and the water evaporates rapidly to form a solid powder. This production method makes the powdered potassium silicate undergo a huge change in physical form while maintaining the same chemical composition as liquid potassium silicate.
Comparison of active ingredient content: The high concentration advantage of powdered potassium silicate
The content is one of the key indicators to measure the quality and application value of chemical raw materials. In the production process of liquid potassium silicate, due to the limitations of process and storage conditions, there is a certain upper limit on the content of active ingredients. In the production process of liquid potassium silicate, in order to ensure the fluidity of the product, the water content usually accounts for 60%-70%, which makes it difficult for the active ingredients of potassium silicate to exceed 40%.
Powdered potassium silicate, after drying, spraying and other processes, removes a large amount of water, making the effective ingredients highly concentrated. The company's independently developed drying process increases the effective ingredient content of powdered potassium silicate to more than 98% by precisely controlling the temperature curve and drying time. In actual testing, the potassium silicate content of powdered potassium silicate is much higher than that of liquid potassium silicate. This high content characteristic makes the use of powdered potassium silicate less under the same use effect.
Take the application of refractory materials industry as an example. When a large refractory material enterprise produces high-alumina refractory bricks, it uses liquid potassium silicate as a binder, and the addition ratio needs to reach 12% to meet the strength requirements; after switching to Hengli Chemical's powdered potassium silicate, only 8% of the addition amount is needed to achieve high-strength bonding of the material, which not only reduces production costs, but also improves the overall performance of refractory materials, and shows better stability and durability in a high temperature environment of 1600℃.
Difference in moisture content: Low water stability of powdered potassium silicate
Moisture content is another significant difference between powdered potassium silicate and liquid potassium silicate. Liquid potassium silicate contains a lot of water due to its own morphological characteristics, which not only increases the weight of the product, but also brings many inconveniences during storage and use. During storage, liquid potassium silicate is easily affected by moisture and undergoes hydrolysis, resulting in modulus changes and product deterioration. The shelf life is usually only 6-8 months.
Powdered potassium silicate has been dried and has an extremely low moisture content. According to a third-party testing agency, its moisture content is controlled within 0.5%, which greatly reduces the risk of chemical reactions caused by moisture and effectively extends the shelf life of the product. During storage, powdered potassium silicate can be stored in a dry and ventilated environment for 2-3 years without the need for special moisture-proof and moisture-proof equipment, reducing the company's storage management and maintenance costs. When a paint manufacturer used liquid potassium silicate, the annual loss rate due to product deterioration reached 15%; after switching to powdered potassium silicate, the loss rate dropped to less than 1%.
Transportation and storage advantages: cost optimization solution for powdered potassium silicate
The transportation and storage links are crucial for cost control and market promotion of chemical products. Due to its fluidity, liquid potassium silicate requires special containers and equipment during transportation, such as sealed tank trucks, plastic barrels, etc., and these packaging and transportation tools are expensive. Calculated based on a transportation distance of 500 kilometers, the unit transportation cost of liquid potassium silicate is about 80 yuan/ton, and there is a risk of leakage during transportation. Once leakage occurs, it will not only cause product loss, but also may cause environmental pollution.
Tongxiang Hengli Chemical Co., Ltd.'s powdered potassium silicate exists in the form of solid powder, which is easy to package and transport. It can use conventional packaging materials such as woven bags and paper bags, and the packaging cost is greatly reduced. The packaging cost per ton saves about 120 yuan compared with liquid potassium silicate. Powdered potassium silicate has a higher density and occupies less space at the same weight, which can effectively increase the vehicle loading capacity during transportation. Taking a 13-meter semi-trailer as an example, the loading capacity of transporting liquid potassium silicate is 25 tons, while the loading capacity of transporting powdered potassium silicate is 35 tons, reducing the unit transportation cost to 50 yuan/ton. For customers who transport over long distances and purchase on a large scale, the advantages of powdered potassium silicate in transportation and storage are more obvious, which can significantly save logistics costs and storage space.
Convenience of use comparison: The flexible deployment advantage of powdered potassium silicate
From the perspective of ease of use, powdered potassium silicate also has outstanding advantages. In actual application scenarios, although liquid potassium silicate can be used directly, in some occasions where precise concentration and dosage are required, dilution and deployment are required, which increases the use process and labor costs. When a precision casting company prepares a binder, the use of liquid potassium silicate requires a special deployment workshop and operators, and each deployment takes 2-3 hours.
However, powdered potassium silicate can be quickly dissolved on site according to specific usage requirements, and the operator can accurately control the dissolution ratio to obtain the required concentration of potassium silicate solution. Tongxiang Hengli Chemical Co., Ltd. optimizes the particle size of the product so that powdered potassium silicate can be completely dissolved in water at room temperature within 5 minutes. Taking the use of potassium silicate as a soil conditioner in the agricultural field as an example, farmers can quickly dissolve potassium silicate powder in the fields according to different soil conditions and crop needs, flexibly adjust the concentration of use, achieve precise fertilization and soil improvement, and improve the efficiency and effect of use.
Comprehensive cost advantage: the economic value of potassium silicate powder
In terms of cost, in addition to the above-mentioned reduction in transportation and storage costs, potassium silicate powder has achieved improved production efficiency and optimized energy utilization through advanced drying and spraying processes during the production process. Tongxiang Hengli Chemical Co., Ltd. produces more than 200,000 tons of various inorganic silicate products annually, and the cost advantage brought by large-scale production is significant. The company uses waste heat recovery technology to reuse the heat energy generated during the spray drying process, reducing the energy consumption per unit product by 25%.
In the long run, for enterprises and industries that use a large amount of potassium silicate, choosing powdered potassium silicate can significantly reduce the overall cost and improve the economic benefits and market competitiveness of enterprises while ensuring product quality and use effect.
Application field expansion: the diversified value of powdered potassium silicate is displayed
The application field of powdered potassium silicate has also been further expanded due to its own advantages. In addition to its wide application in refractory materials, agriculture and other fields, in potash fertilizer production, the high content and low moisture characteristics of powdered potassium silicate enable it to be better mixed with other fertilizer components to improve the stability and fertilizer efficiency of potash fertilizer. In the application practice of a compound fertilizer production enterprise in Shandong, the agglomeration rate of compound fertilizers with the addition of powdered potassium silicate was reduced by 40%, and the duration of fertilizer effect was extended by 30%.
In the field of high-temperature resistant adhesives, powdered potassium silicate can be quickly formulated into suitable adhesives according to different usage scenarios to meet the bonding needs of different materials in high temperature environments. In contrast, due to its morphology and performance limitations, liquid potassium silicate cannot achieve the effect and convenience of powdered potassium silicate in some application scenarios. In the bonding of parts in the aerospace field, the adhesive formulated with powdered potassium silicate can maintain structural stability at a high temperature of 1200°C, while liquid potassium silicate cannot meet this performance requirement.
