- The better the mechanical and physical properties. High-strength and high-modulus PVA fiber has high tensile strength and modulus, low elongation, and tensile strength comparable to that of steel bars. The elastic modulus is matched with that of concrete, which can improve the early tensile strength of concrete. Increasing the tensile strength of concrete in the middle and late stages can greatly save construction and maintenance time and shorten the construction period.
- High affinity with cement. High-strength and high-modulus PVA fiber has good affinity with cement, and the bonding strength is better than nylon 6, polypropylene, polyester and other fibers. Due to its special molecular structure, the adhesion between PVA fiber and the brittle cement interface is good, and it plays a role of reinforcement.
- Good dispersion. High-strength and high-modulus PVA fibers do not adhere to each other and disperse well in water. The fibers are evenly dispersed in the concrete, distributed in random directions, and overlap each other to form a three-dimensional network structure. In the concrete, it can change the brittleness of concrete, increase its toughness, and improve the properties of crack resistance, seepage resistance, frost resistance, and impact resistance of concrete, thereby improving the overall quality of concrete and improving the durability of concrete.
- Good alkali resistance and weather resistance. High-strength and high-modulus PVA fiber has good chemical stability. It will not chemically react with any materials in the concrete after being mixed into concrete. Its acid and alkali resistance and chemical resistance are all comparable to other fibers such as man-made fibers, nylon 6, polyester, etc. .
- Good light resistance and corrosion resistance. High-strength and high-modulus PVA fibers have a fiber strength loss rate much lower than other fibers under long-term sunlight, and the fibers will not be moldy, corroded, or moth-eaten when buried in the ground for a long time.
- Green and environmentally friendly, no pollution. The high-strength and high-modulus PVA fiber does not produce dust and is inhaled into the human lungs during transportation and use, and will not decompose toxic gasses when encountering high temperatures, and is harmless to humans and the environment.

Technical Details & Test Data
- Technical Information
High-strength and high-modulus PVA fiber has high tensile strength and modulus. Due to its acid and alkali resistance, anti-aging, corrosion resistance, ultraviolet resistance and other properties, it is harmless to human body and the environment and is ideal for replacing industrial asbestos. Materials are widely used in high-performance concrete engineering domains and special domains such as coinage and military.
Wanwei high-strength and high-modulus PVA fiber has been awarded the title of "Class New Product". Its production technology is advanced and it has many innovative technologies. Among them, the neutralization water washing device has won the patent. The industry standard of "High-strength and high-modulus polyvinyl alcohol ultra-short fiber" drafted by Wanwei Company (standard number: FZ/T 52023-2012) was officially announced by the Ministry of Industry and Information Technology and filed by the Standards Committee on June 1, 2013. The implementation marks another important step taken by Wanwei Company in continuous independent innovation.
Wanwei now has 16 high-strength and high-modulus PVA fiber production lines with an annual production capacity of 35,000 tons. Its varieties mainly include high-strength and high-modulus PVA fiber W1 fiber, high-strength and high-modulus PVA fiber W2 fiber, high-strength and high-modulus PVA fiber W4 fiber, and PVA fiber for concrete. The products have passed ISO9001 quality management system and ISO14001 environmental management system certification. Over the years, it has been sold well in more than 20 regions and regions such as Europe, America, Southeast Asia, and Africa.Use green materials to keep away from asbestos hazards
Asbestos is a kind of silicate with fibrous structure. In the building materials industry, it is mainly used as insulation material and some building materials, such as asbestos cement products. The harm of asbestos to humans did not cause widespread concern until the 1980s.
At the beginning of this century, "Asbestosis" (Asbestosis) has been discovered, and it is confirmed that it is caused by inhalation of asbestos dust, but it is only regarded as a kind of "silicosis", which is not directly related to the formation of lung cancer. Later, after a large number of clinical studies, it was discovered that asbestos dust can cause "Mesothelioma" (Mesothelioma). The so-called "mesothelioma" is a cancer of the sternum or peritoneum. It is a disease with an incubation period of 30-45 years. It is observed that if there is less than gram of asbestos remaining in the lungs, severe lung cancer may occur, while less than 1 mg of asbestos remaining in the sternum and peritoneum can cause "mesothelioma".
Diseases caused by asbestos so far, no good curable drugs have been found, the only way is to prevent, try not to touch asbestos products, or take effective protective measures when contacting them. Asbestos fiber cement products used for interior and exterior wall decoration and indoor ceilings. The fine asbestos fibers contained in the asbestos fiber may cause asbestos lung disease if it is inhaled by people. pain of.
Since the United Nations International Labor Convention No. 162 on the Reliable Use of Asbestos came into force in 1989, the world has begun to ban the use of asbestos-containing products and prohibit any form of asbestos distribution. From 1990 to 2000, the European Community, the United States, Canada, Singapore, Chile, and Australia, etc. and other regions have enacted legislation to prohibit the sale or use of asbestos-containing fibers and products within their borders. With the continuous convening of the Conference of Contracting Parties to the Rotterdam Convention every two years, calls for the prohibition of asbestos in other countries are also increasing. The global prohibition of asbestos has become the general trend and popular desire.
Since 2000, my country began to carry out research on asbestos substitute fibers and produce non-asbestos cement products, and has achieved success. On December 27, 2012, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the Ministry of Environmental Protection of China jointly issued the "Encouraged Substitution of Toxic and Hazardous Materials (2012 Edition)", listing high-strength and high-modulus PVA fibers as a replacement for asbestos. Designated products with large promotion efforts.
In our country, the massive use of asbestos tiles on construction sites and even the use of asbestos nets in middle and high school chemical laboratories is very worrying. Some companies in our country have realized the dangers of asbestos and have begun to produce non-asbestos cement boards. For our next generations, when decorating and refurbishing houses, when conditions permit, it is better to use non-asbestos cement products.
