The high performance fine sand has a uniform particle size distribution.
The high-performance fine sand is a building material subjected to strict screening and treatment, has uniform particle size distribution, higher density and hardness, has uniform particle size distribution, and means better stability and bearing capacity, the stability of the fine sand is critical for ensuring the safety and durability of a building in a building structure, the high-performance fine sand has higher density and hardness, so that the fine sand has better wear resistance and compression resistance, the wear resistance and compression resistance of the fine sand are critical for ensuring the quality and durability of the building in the building material, and the high-performance fine sand also has better permeability and filtration, which means that the high-performance fine sand can play a better role in treating sewage, rainwater and the like. When sewage and rainwater are treated, the permeability and filterability of the fine sand can help to filter out impurities and pollutants, thereby ensuring the cleanness and safety of water quality.
The fiber reinforcement material is polypropylene fiber and has a certain length and strength.
The fiber reinforced material plays an important role in the composite material, while the polypropylene fiber is one of the common fiber reinforced materials, the polypropylene fiber has the characteristics of excellent chemical stability, corrosion resistance, ageing resistance and light weight high strength, the fiber reinforced material has the functions of providing strength and rigidity, improving certain properties of the material, the polypropylene fiber has higher strength and modulus, can effectively improve the strength and rigidity of the composite material, meanwhile, the polypropylene fiber also has good corrosion resistance and ageing resistance, can ensure that the composite material keeps stability and durability under severe environmental conditions, the length and strength of the polypropylene fiber are important factors influencing the performance of the composite material, in general, longer fiber can provide better reinforcing effect, but overlong fiber can influence the processability of the composite material, so when the polypropylene fiber is selected, the length and the strength of the fiber need to be determined according to specific application and processing requirements, the price of the polypropylene fiber is relatively low, the cost of the composite material can be reduced, and meanwhile, the polypropylene fiber also has the characteristic of recycling and meets the requirement of sustainable development.
The adhesive is acrylic emulsion and has high adhesive strength.
The adhesive is an important chemical material and has wide application in many fields, the acrylic emulsion is a common adhesive, and has many advantages such as high adhesive strength, water resistance and weather resistance, the acrylic emulsion has high adhesive strength, which means that different materials can be effectively adhered together to form a firm adhesive layer, the adhesive strength can resist various external forces such as tension, pressure and impact force, the acrylic emulsion also has good water resistance and weather resistance, which means that the acrylic emulsion can keep its performance stable under various environmental conditions and is not easy to be influenced by moisture and ultraviolet rays, therefore, the acrylic emulsion can keep its adhesive strength and stability for a long time when being used outdoors, aging or falling off is not easy to occur, and the acrylic emulsion has other advantages such as easy construction, high curing speed and low cost.
The water-cement ratio of the pointing agent is 0.3-0.5.
The water-cement ratio is a very important parameter in the preparation of the pointing agent, and refers to the ratio of water to cement used in the preparation, for pointing agents the water-cement ratio is usually controlled between 0.3 and 0.5, the selection of this water-cement ratio range is based on the requirements on the properties of the pointing agent, if the water-cement ratio is too high, it will result in too weak pointing agent, lacking sufficient strength and durability. If the water cement ratio is too low, the pointing agent is too hard and brittle and is easy to crack and peel, so that good workability and durability can be ensured.
The drying time of the pointing agent is 4-8 hours.
Different pointing agent brands and types may have different drying times, some brands may require longer time to dry completely, while other brands may dry faster, in addition, the use of different pointing agent formulations and additives may also affect the drying time, environmental factors may also affect the drying time of the pointing agent, for example, temperature and humidity may affect the drying speed of the pointing agent, in a humid environment, the pointing agent may require longer time to dry completely, while in a dry environment, the drying time may be shortened, construction conditions and methods of use may also affect the drying time of the pointing agent, if the temperature is too high or too low during construction, or if the pointing agent is not mixed in the correct proportion during construction, may result in the drying time being prolonged, in order to ensure that the drying time of the pointing agent meets the requirements, it is recommended to know the drying time characteristics of the product before use, and select appropriate construction conditions and methods of use, and at the same time, care is taken during construction to ensure that the best results in the pointing or missing of the drying effect can be achieved completely.
