What is Pva Powder?

The glass adjustment temperature level is 60-85 ° C. Polyvinyl alcohol contains several alcohol groups, is polar, and also can create hydrogen bonds with water, so it can be liquified in polar water. Polyvinyl alcohol is furthermore soluble in warm hydroxyl-containing solvents such as glycerin, phenol, etc, yet insoluble overall organic solvents such as methanol, benzene, acetone, gas, and so forth.

Pva Powder Uses

  1. Pva Powder is primarily used for warp thread dimension, fabric completing agent, and vinylon fiber resources in the fabric market; 107 adhesive, interior and exterior wall surface coverings, as well as adhesives in the building and construction and decor market; as a polymeric emulsifier, dispersant, as well as polyvinyl official in the chemical industry, acetal, butyral material; utilized as paper adhesive in paper sector; utilized in agriculture as soil improver, pesticide bond synergist and also polyvinyl alcohol movie; additionally used in daily cosmetics and also high-frequency quenching representatives and so on.
  2. Pva Powder is mostly used for the manufacturing of tarpaulins, canvases, rubber conveyor belts as well as cord fabrics for rickshaw tires, ropes, fishing webs, packaging materials, and so on for storage space.
  3. Pva Powder is commonly made use of in the internal packaging of industrial, chemical products as well as civil assets.

Application of Pva Powder Water Soluble Fiber

Applications in the textile industry
①Application in wool spinning industry
10%~20% water-soluble Pva Powder fiber tops are mixed with wool and spun to make fabrics, and then the water-soluble fibers are removed in the dyeing and finishing stage, which can increase the wool count by about 20%, thereby obtaining light weight, Soft, fluffy, drapable and elastic wool fabric.

②Application in cotton spinning industry
After PVA water-soluble fiber and cotton are blended into yarn, knitting or weaving is used to make gray fabric, and Pva Powder water-soluble fiber is removed in the post-processing, which can obtain a thin, soft, cool spinning style, moisture absorption, breathability, and comfortable wearing. Excellent wearability. Compared with traditional textiles that use Xinjiang long-staple cotton and imported Egyptian cotton as raw materials, and can only spin high-count yarns with sophisticated spinning equipment and strict and reasonable process conditions, it greatly reduces production costs and improves product quality. After the towel is made of core-spun yarn with water-soluble fiber as the skin and cotton fiber as the core, the water-soluble fiber is removed by hot water treatment. The untwisted fluff towel produced by this method has the characteristics of fullness, softness, and high water absorption. This kind of towel also has the characteristics of not cutting the velvet but slightly shining. It looks like a velvet towel to the eye and feels like a high-end towel.

③Application of PVA water-soluble filament
Pva Powder water-soluble filament can be dissolved in water at 5~100℃, has ideal water-soluble temperature, high strength, good acid and alkali resistance, and dry heat resistance. The PVA water-soluble filament is woven between two socks to be separated instead of ordinary yarn, and the process of separating the socks by an automatic separator or scissors is eliminated. Water-soluble fibers are used for fabric warp sizing, which has the advantages of uniform sizing, stable chemical structure, good corrosion resistance, and simple and easy process. Use PVA water-soluble filaments as weft yarns to weave, and then dissolve the weft yarns in hot water to make weft-free blankets. Water-soluble nonwovens can be used as the base fabric for embroidery in the garment industry. After processing, the nonwovens are disposed of in hot water to obtain hollow and three-dimensional embroidery.

④Application in military
Surface mines block ports or waterways, water-soluble parachutes for air-dropped secret agents, and protective work clothes for nuclear submarine operators must be made of water-soluble fibers.

Application in paper industry
At present, my country’s paper industry is facing two major difficulties. One is that the quality of such pulp has dropped significantly due to the dwarfing of wheat stalks and the degradation of reeds. However, the quality of waste paper pulp is low, how to ensure the quality of paper products and reduce the cost has become a difficult problem for paper mills. Adding an appropriate amount of Pva Powder water-soluble fiber to the paper can significantly improve the paper strength, damage resistance, folding resistance, tearing degree and surface printing strength. The strengthening mechanism is that the PVA water-soluble fiber has a large number of hydroxyl groups on its macromolecules, which can form a large amount of hydrogen bonding force with the pulp fiber, and can dissolve into a semi-soluble bonded fiber when the paper is dry. The strength of the water-soluble fiber is much greater than that of the pulp fiber. Therefore, It can greatly improve the strength of paper.

Pharmaceutical Application of Pva Powder

Pva Powder hydrogel is widely used in the biomedical field due to its water content, elastic modulus, low friction coefficient, high mechanical strength, rich pore and leaky network structure, and good biocompatibility, which are similar to those of natural human tissues. Has a wide range of applications. It can be used to manufacture artificial cartilage, artificial cornea, artificial vitreous body, etc. Polyvinyl alcohol hydrogels are widely used in ophthalmology and can be used to make soft contact lenses. Because of its water solubility, it can also be made into drug sustained-release capsules. A new type of medical non-fibrous sponge formed by introducing sodium polyacrylate side chains on the PVA macromolecule, called ionized polyvinyl alcohol sponge (i-PVA sponge for short), has good biocompatibility and stable chemical properties, and has excellent Excellent hydrophilic, liquid and blood-absorbing properties. i–PVA sponge can be effectively used in medical operations such as microsurgery and eye surgery that strictly require no fiber shedding, especially in cataract intraocular lens replacement surgery.
