Our company will have the Chinese New Year holiday from February 1st to February 13th, 2019. Since the logistics company will stop transport operation in around January 25th, our company decides to only accept orders during this period and does not arrange shippment till the end of the Chinese Spring Festival. Hereby inform the customer Shijiazhuang City Horizon Chemical Industry Co., Ltd. wish you have a Happy New Year.

PLEASE CHECK BELOW BANK INFORMATION AGAIN WHICH IS AS SAME AS BEFORE AND WE WILL NEVER CHANGE. IF YOU RECEIVE AN EMAIL TO ASK YOU TO CHANGE THE ACCOUNT, PLEASE MAKE A PHONE CALL TO CONFIRM WITH US. THIS WILL HELP TO PREVENT THE CHEATS TO LIE BOTH OF US AND LOSE OUR MONEY.

Triethanolamine is an important fine chemical product and a commonly used raw material for cement grinding aids and concrete admixture manufacturers. Triethanolamine (TEA) can form a water-soluble chelate with cations in cement hydration system, and forms many melting points on the surface of cement particles, which increases the dissolution rate of C3A and C4AF, resulting in faster reaction with gypsum. The increased amount of calcium sulphoaluminate is beneficial for coagulation and compaction, thereby increasing early strength. At the same time, due to the formation of unstable complexes in the hydration process of cement, the degree of supersaturation of Ca(OH)2 is increased, which can effectively prevent the formation of loose crystalline products in the early stage of C3A hydration, thereby improving the compactness of cement stone and strength.

افزودنی های بتنی (انگلیسی: افزودنی های بتنی) به مواد افزودنی اشاره دارند که مواد مورد استفاده برای بهبود عملکرد بتن قبل از مخلوط کردن یا مخلوط کردن هستند. مقدار افزودنی بتن به طور کلی بیش از 5٪ از جرم سیمان نیست. پس از علاوه بر این از مواد افزودنی بتن، با توجه به گونه های مختلف، اثر تولید شده نیز متفاوت است، عمدتا تولید یک اثر فیزیکی، به عنوان مثال در سطح ذرات سیمان فیلم جذب تشکیل شده است، این تغییرات بالقوه، و در نتیجه دافعه یا جاذبه مختلف جذب و برخی از اراده لخته آسیب ساختاری، افزایش ثبات سیستم انتشار سیمان، بهبود شرایط هیدراتاسیون سیمان: برخی از سازه های ماکرومولکولی می تواند تشکیل شود، دولت در حال تغییر از سطح ذرات سیمان جذب شده هستند؛ برخی خواهد کشش سطحی آب و انرژی سطحی و مانند آن را کاهش می دهد: وجود دارد چند نفر به طور مستقیم در واکنش های شیمیایی شرکت می کنند، با سیمان برای تشکیل ترکیبات جدید.

With the rapid development of China's cement industry, the pressure of energy saving and emission reduction is getting bigger and bigger, cement production enterprises will pay more and more attention to the application of grinding aids, and the application prospect of grinding aids will be very broad. The main raw material used by some foreign companies for grinding aids is de-sugar wood sulfonate. The use of industrial by-products as cement grinding aids has a very broad application prospect. Some foreign scientists use natural bio-glycerol, a by-product of biodiesel manufacturing, to replace common cement grinding aids such as ethylene glycol and hydroxylamine for cement grinding process. Using cement from different regions of Belgium, Greece and Italy, it was found that this bio-glycerol blended with 5% NaCl was more effective than the high-purity grade glycerol. In addition, this bio-glycerol can significantly improve cement.

In the field of cement grinding aids, the early alcohol amine compounds used in cement grinding aids are mainly triethanolamine due to triisopropanolamine. The dispersibility and late strength are superior to triethanolamine, and its market share is expanding. Compared with triethanolamine, triisopropanolamine The divergence, the enhancement of each age, and the application conditions have the following advantages

With long-time and rich experience working in the field of construction chemicals, Horizon Chemical concrete water reducing agent and cement grinding aid series has been well accepted. And by introducing the new technology, Haisen developed the new type ASA film and PEA series products to apply to the field of outdoor protection and some other high-end market.

ASA resin is formed by blending polyacrylate core-shell copolymer with SAN, which can significantly improve the weather resistance of ASA resin and low temperature or normal temperature impact resistance, and does not affect other physical properties of ASA resin, making ASA resin easier to process, Excellent surface finish and good rigidity can be widely used in various co-extruded plastic products or other plastic products. Another aspect of the present invention provides a plastic film comprising the ultraviolet-resistant weather resistant ASA resin as described above. In the specific molding, the components of the above-mentioned formulation are blended, stirred and mixed uniformly in a high-speed mixer, and then granulated, and the granulated resin is heated and melted by an extrusion molding machine, and the formed film is stretched.

The UV-resistant weather-resistant ASA resin is formed by blending a polyacrylate core-shell copolymer (ie, PBA-MMA) with SAN, which can significantly improve the weather resistance of ASA resin and low-temperature or normal-temperature impact resistance without affecting other physics of ASA resin. performance. ASA resin has high UV resistance and weather resistance, is easy to process, has excellent surface finish, and maintains good rigidity. It can be widely used in various coextruded plastic products and films. In the polyacrylate core-shell copolymer, MMA can make the core-shell copolymer and the acrylonitrile-styrene copolymer have good compatibility, and the acrylate core and the acrylonitrile-styrene copolymer are grafted to form a high. UV-resistant, highly weather-resistant ASA resin.

The chemical admixture is a component of concrete other than Portland cement, water and aggregate added to the mixture before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transport, placement and solidification; and to overcome certain emergencies in specific operations. Successful use of admixtures depends on the use of appropriate ingredients and concrete casting methods. Most admixtures are supplied in ready-to-use liquid form and added to the concrete in the factory or on the job site. Certain mixtures, such as pigments, bulking agents, and pumping aids, are used only in very small amounts and are typically batched by hand from pre-measured containers. The effectiveness of the mixture depends on several factors, including: type and amount of cement, water content, mixing time, slump, and temperature of concrete and air.
