    Waste rubber powder is refers to the products after the crushing process of powdered rubber materials processing, plastic playground, amusement park, rubber floor tile is widely used in sports, waterproofing materials, waterproofing coating, modified asphalt, rubber products, modified starch, broadly higher fields.

    Product introduction

    This product USES the modified hydroxypropyl methyl cellulose (HPMC) as raw materials, biodegradable, no residue, environmental protection, non-toxic harmless; Good solubility and dispersion, stable performance, easy construction, daub area is large; Can mouldproof moistureproof, is a new generation of green health and professional wallpaper powder.

    The use of preparation

    Ensure metope smooth, clean, dry, tools are also clean. When necessary the stains on the wall can use the decontamination treatment to remove, mildew areas must be treated with bleaching liquid before use detergent. Ensure metope is painted or at least the basement membrane.

    Modulation method

    According to dissolve the scale, pour cold water;Slowly pour into powder, stirring edge;Mixing powder and water until the mucilage thickening;After formation liquid glue, let stand for 10 to 15 minutes

    The glue method

    Evenly on the back of the wallpaper wallpaper mucilage, the wall paper folded let stand for 5-10 minutes, the glue liquid paste after full invasion wallpaper

    Modulation method

    According to the baseline will wallpaper top-down paste on the wall;With scraper scrape excess wallpaper glue and bubble;Use a wet towel to wipe wallpaper surface wallpaper

    Dissolve the scale
    The wallpaper type Add water Mixing time Cover area
    Heavy wall paper 3-4 liters 5 minutes 15-20 square metre
    Ordinary wallpaper 6-7 liters 5 minutes 45 to 50 square meters

    Ratio of * note: this table is for reference only, if found in the construction process of abnormal, please immediately stop the construction, professional technical advice and counseling.

  • The basic classification

    According to the different methods can be classified, according to the process can be divided into normal temperature powder, frozen powder, putty powder, instant powder, superfine powder and fine powder; According to the sources of raw materials can be divided into the truck tire rubber powder, passenger tire rubber powder and shoe rubber powder, etc., according to the activation or not can be divided into activated powder and not activation powder; According to the size of the particle size of ultrafine powder and general powder

  • The basic classification

    Waste rubber rehearsals

    After sorting and divide without a rubber composition of waste rubber, due to the different length, thickness, not directly to pieces, and have to be cut for waste rubber. Overseas for common use whole tire cutter cut into range 25 mmx25mm rubber pieces. Large plastic block is back to cutting machine to cut again.

    Crushing
    The normal temperature FenSuiFa

    Mainly using shear to cut waste rubber, crushing, generally divided into coarse crushing and finely two processes. At room temperature to room temperature in grinding roll method and continuous FenSuiFa is most commonly used tyres. Room temperature FenSuiFa jiaofen production in the world is the main method, has a good technical economy.

    Low temperature FenSuiFa

    According to different can be divided into liquid nitrogen freezing medium adopted by the expansion refrigeration FenSuiFa FenSuiFa and air at low temperature. It is using the low temperature effect, make the rubber brittle glass transition temperature is reached, and then use mechanical force to crush it. Liquid nitrogen method of liquid nitrogen consumption big, high cost; The cooling medium for air expansion refrigeration FenSuiFa, air, a liquid nitrogen method of energy saving, water saving, high efficiency and low cost.

    In the industrial developed countries, have subsidy to waste rubber processing, so can use liquid nitrogen and air expansion refrigeration FenSuiFa. Developing countries and subsidies, the country should be under normal temperature method is used to produce powder to adapt to the market and obtain better economic benefit.

    Wet method or solution method

    Choose the appropriate liquid medium make rubber brittle, and then on the colloid mill for grinding. According to its using suspension liquid medium water expansion shattered two crushing and solvent. Water suspension pieces for the surface treatment of powder grinding after drying in the water; Solvent crushing using organic solvent make powder swelling after grinding, and then remove the solvent and dry powder. Wet method or solution method producing fine powder particle size, application performance is good, but its high production requirements, need to use a large amount of liquid medium.

  • The performance characteristics of

    Powder engineering, powder is a kind of powder and granular materials, so for powder particle size, specific surface area, surface morphology and group and its components for the use of it will have important influence on performance.

    The fine powder is, the performance is better. The fine powder of the vulcanizates of tensile strength, elongation and abrasion, and the closer in without powder. And fatigue resistance, resistance to crack growth performance are higher than without powder, the greater the increase of the thinner.

  • Current situation of the development of

    In 1930, in the United States to declare the first patent on rubber powder. In 1956 the United States B.F.G oodrich company produce nitrile rubber powder for the first time. Since then, many scholars abroad for rubber powder has carried on the positive research, this new product develop powder styrene butadiene rubber. Dunlop company developed powder ethylene propylene rubber and silicone rubber powder; American esso company developed butyl rubber powder; Harrison British company established powder natural rubber factory in Malaysia. But later in the nearly 20 years, due to various reasons, the development of rubber powder stagnant

    Until the 1980 s, production and application of rubber powder. The powdered rubber processing equipment has achieved rapid development.

    In the late 1990 s,ue to the rapid development of the polymer modified industry and tire industry needs to expand, rubber powder production and processing technology, and the global environmental protection requirements, using waste rubber of rubber powder preparation technology has also got rapid development.

    The study of powdered rubber in our country, from the 1970 s, lanzhou institute of chemical industry company synthetic rubber factory for the start of the study of powdered rubber products.

Merlot, wallpaper glue

Many regions in our country is refers to the "gelatin and bone glue, leather glue" by certain grinding processes into pieces, powder of fine chemical products. Usually refers to gelatin products in hebei, shandong area, can be processed into 5-120 mesh. The fine powder, the longer time for processing, when using the faster dissolution rate. Appearance of powder is white, pale yellow to yellow or amber color, translucent, not smell, no visible impurities.

The molecular weight of 1-100000, contains 18 kinds of amino acid, water and inorganic salt content is below 16%, protein content in more than 82%, is a kind of ideal protein source. Products are widely used in photographic materials, medicine, furniture, packaging, paper making, textile, printing and dyeing, printing, ceramics, cosmetic, food, paint, metallurgy and other industries of various kinds of products, and in which the
main thickening, stable, condensation, harmonic, polishing, sizing, solid water
and so on. According to incomplete statistics, more than 30 industry, more than 1000 kinds of products using the powder. Of course, different industries, different products have different level requirement about the quality of the powder.
