What factors affect the price of water reducing agent? Generally speaking, there are macro factors and micro factors. On the one hand, it is mainly the market situation, followed by factors such as materials, size, model, brand, etc.; different materials create Different products; the impact of cement characteristics on the plasticizing effect of water-reducing agents. Different types of cement will have different plasticizing effects of water-reducing agents. Below, the editor will help you understand the factors that affect the price of water-reducing agents.
The mineral composition and chemical composition of cement clinker and the form of gypsum (used as a setting regulator) will all affect the plasticizing effect of the water-reducing agent. In addition, the fineness of the cement, the type and amount of admixtures in the cement, the freshness of the cement, the moisture content and temperature of the cement, etc. will also affect the plasticizing effect of the superplasticizer. The characteristics of the product will also affect the price of water reducing agent.
The ratio of water reduction rate to concrete
The amount of high-strength concrete used in current construction projects is not large, and medium-strength and low-strength concrete are mainly consumed in the project. Therefore, in the mixing and production of medium and low-strength concrete, polyhydroxyacid-type high-performance water-reducing agents are widely used.
①Use polyhydroxyacid water-reducing agent to adjust the concrete grading. Since the polyhydroxyacid type water reducing agent has a good water reducing rate, it can be directly used in the mixing of medium and low strength concrete. Proper adjustment of the concrete proportion can ensure the water reducing rate of concrete. When it is necessary to increase the water reduction rate of concrete, the dosage of cement and water can theoretically be reduced. However, if the cement content is too small, it will have an impact on the quality of the concrete. Therefore, it is better to use polyhydroxyacid water-reducing agent to adjust the concrete ratio than to use cement. adjustment effect.
②Configure medium-efficiency water-reducing agent. In order to meet the water reduction rate of concrete, the amount of water reducing agent needs to be adjusted appropriately, but during the adjustment process, it will have a certain impact on the slump retention of concrete. Therefore, in order to ensure slump retention during mixing of medium and low-strength concrete, the corresponding polyhydroxy acid medium-effective water reducing agent can be synthesized to ensure slump retention and water reduction rate while also controlling costs.
What factors affect the price of general water-reducing agents? The following two points will be explained from the market perspective:
1. The payment method for the purchase of industrial naphthalene raw materials by naphthalene-based water-reducing agent companies Generally, it is paid in advance, that is, cash on hand. No matter what the market status of industrial naphthalene is, the downstream generally implements this method to complete the transaction. That is, the industrial naphthalene production enterprise can ensure the timely return of funds after shipment. The reduction of inventory means the increase of working capital. Increase, and water-reducing agents are sold downstream through mixing stations, engineering construction, construction developers, and end consumers. It takes a certain amount of time for funds to be withdrawn. The key depends on whether all links in this industry chain are operating smoothly. Some naphthalene-based water-reducing agent companies It reflects that it will take at least a month for the funds to be withdrawn, which will have a certain impact on the purchase of industrial naphthalene; naphthalene-based water-reducing agents are a transitional link between the coal chemical industry and the construction industry, and differences in payment methods may cause market disconnection.
2. In the past, industrial naphthalene was mainly used to produce phthalic anhydride, and the oversaturated industrial naphthalene market has been in a weak state; the rise and development of the naphthalene series water-reducing agent market has become the main demand market for industrial naphthalene, with good The water-reducing effect has made it the water-reducing agent product with the largest market share in the water-reducing agent industry. The high-cost water-reducing agent companies have low profits or even breakeven production, and some companies have to start to choose other series of products, such as anthracene, aliphatic, acetone, polycarboxylic acid, etc. Naphthalene-based water-reducing agents are more likely to cause problems during the production process. Regarding pollution problems, the state advocates polycarboxylic acids to enhance environmental protection. However, the current cost of such products is relatively high. Some people predict that based on the current coal tar processing industry, the output of industrial naphthalene will not increase in the future, and the price of industrial naphthalene may be at a certain high level. It fluctuates up and down within the range. It is expected that in 5 years, other series of water reducing agents will have a greater market impact on naphthalene series products.
Everyone has enough knowledge about the factors that affect the price of water-reducing agents. I hope that friends who are interested in this can gradually learn more.
