Home renovation, hydropower transformation is the first step, followed by waterproofing. Regarding waterproofing, there are three kinds of waterproof materials on the market. Each of the three materials has its own characteristics. In the field of household waterproofing, who is the most suitable waterproof material, and look at the following analysis.
First, comparison of material properties and constituent materials
The new polymer cement-based waterproof material is an aqueous waterproof material, which is composed of an organic polymer liquid material and an inorganic powder material, and combines the advantages of high elasticity of the organic material and good durability of the inorganic material. Moreover, such coatings are non-reactive products, and the factory is strictly processed according to the formula, so the quality stability is high.
The 911 polyurethane is generally an oily waterproof material. A isocyanate group-containing prepolymer obtained by addition polymerization of an isocyanate or a polyether, and a single component prepared by a process such as a catalyst, an anhydrous auxiliary agent, a water-free filler, a solvent, and the like. Polyurethane waterproof coating. Urethane coatings are generally synthesized and synthesized by manufacturers. Their performance, process control, raw materials and many other aspects may cause quality differences. Especially for some small manufacturers, the conditions are simple and the quality of employees is low, so it is difficult to guarantee quality.
Second, compare construction convenience and construction efficiency
The new polymer cement-based waterproof coating is simple to construct and greatly improves construction efficiency. Direct agitation can be applied in the correct way to form a strong waterproof layer.
Third, compare the resistance of materials against age
The new polymer cement-based waterproof coating combines the high elasticity of organic materials with the durability of inorganic materials. After coating, it forms a high-strength and tough waterproof coating film, which has the advantages of good waterproof performance, anti-aging, anti-cracking, etc. It is environmentally friendly, convenient to construct, and can maintain the product characteristics as usual in a harsh and humid environment;
Oily polyurethane is afraid of ultraviolet light and has poor weather resistance, so it can only be used for concealed engineering waterproofing;
The waterproof membrane is made of petroleum extract, which is prone to aging, cracking, peeling and delamination in the natural environment.
Fourth, compare the total cost
Cement-based waterproof materials are 1.5-2.0mm in accordance with national standards, with low dosage and low cost;
The oil-based polyurethane polyurethane waterproof material requires a thickness of 2.0-3.0mm per square meter of material at least 2.5-3.0kg, and the amount of material is large;
The waterproof coiled material is complicated to be spliced ​​in the home construction, and the labor cost is extremely high.
Cement-based waterproofing materials greatly reduce labor costs due to their high efficiency.
Fifth, consider the safety of construction
Cement-based waterproof coatings and waterproofing membranes can be constructed in any safe environment.
Oily oily polyurethanes require construction in a closed environment, which not only causes poisoning of construction workers, but also causes explosions.
Nylon Screws are made of top level nylon material. They are very light and have an very economic price. They are widely used in Drone industry because of their features. We often offer black and white color. Both cross and slotted head nylon screws are available.
