Anhui Quality Supervision Bureau released: the sampling rate of plastic pipe is 83.3%


The Anhui Provincial Quality Supervision Bureau reported on the 23rd the results of the provincial supervision and inspection of plastic pipe products in 2014. A total of 30 samples were taken and 5 samples were unqualified. The sampling pass rate was 83.3%.

The inspection basis of this spot check is the "Detailed Implementation Rules for Quality Supervision and Inspection of Plastic Pipe Products" and the national standard GB/T 5836.1-2006 "hard polyvinyl chloride (PVC-U) pipe for building drainage", GB/T 19472.1-2004 Polyethylene (PE) structural wall piping system for the ground Part 1: Polyethylene double-wall corrugated pipe, JG 3050-1998 "Insulated electrical bushings and fittings for construction", CJ/T 270-2007 "Polyethylene plastic steel winding drainage Tube, GB/T 18477.1-2007 "Hard Polyvinyl Chloride (PVC-U) Double Wall Corrugated Pipe for Buried Drainage", DL/T 802.3-2007 "Technical Conditions for Power Cables - Part 3: Chlorinated Polychlorinated Ethylene and rigid PVC plastic cable conduits, DL/T 802.2-2007 "Technical conditions for ducts for power cables - Part 2: Glass fibre reinforced plastic cable ducts", for density, Vicat softening temperature, methylene chloride immersion test, Tensile yield strength, longitudinal retraction rate, drop impact test, ring stiffness, ring flexibility, impact properties, oven test, compression resistance, bending properties, bending properties, drop properties, heat resistance, flame retardancy, electrical Performance, flattening test, tensile strength

After inspection, the tensile yield strength and density of the four groups of building hard PVC (PVC-U) pipe products are unqualified. The nominal production enterprises involve Anhui Lantong Building Materials Co., Ltd. and Anqing Baitong Plastics Co., Ltd. Industry Technology Development Co., Ltd., Anqing Futong Pipe Industry Co., Ltd., Tongcheng Lingzhi Pipe Industry Co., Ltd. Another group of products with unsatisfactory tensile yield strength project is the “Zhengjie” U-PVC drainage pipe (φ110×3.2 2013.05.06) produced by Wuhu Shuanghu Plastic Pipe Co., Ltd., which is also known as Anhui Province.

According to the quality supervision department, density is an indicator for limiting the amount of calcium carbonate filled or adding other low-density raw materials. The unqualified density reflects the fact that there is still too much calcium carbonate filling in the drainage pipe products.

Tensile yield strength is one of the important indicators of the mechanical properties of the pipe, which reflects the basic strength of the pipe. Products with unsatisfactory tensile yield strength will be prone to breakage, breakage, cracking and other hazards during installation and use. Once these inferior products flow into the construction project, they will bring greater quality hazards.

1. Product introduction

   Magnetic Water Purifier Granular Activated Carbon is the appropriative Activated Carbon for aquarium to remove fish odor Filter Material . Its unique dense porous structure has good effect to decompose fish feces and food residue, remove smell, heavy metal pollutants and chlorine, decolorization, balance pH value; high dynamic adsorption rate, which can quickly remove various pollutants in water, rapidly increase the water clarity; it can make the fish surface microglia produce protective film, especially has great function for control and repair ornamental fish rotten, unfinished and rotten mouth.  


2. Application

a. Magnetic water purifier Granular Activated Carbon has a strong adsorption for bacteria and decomposition of fecal capacity, most suitable for the multi dung tanks.

b. Magnetic water purifier granular activated carbon is suitable for seedling cultivation in the seawater, seawater purification, and also effectively remove pollutants in seawater, restore water quality, improve the survival rate of seedlings.

3. Process  

  Coal-based granular activated carbon with high quality Anthracite as raw material, it produced by high temperature steam, and by carbonization, activation, crushing and sieving process.

4. Transportation and packaging

a. Woven bag, lined with plastic film bags, each 25kg, also be packaged according to customer demand; activated carbon in the transportation, to prevent mixed with hard materials, do not step,to prevent carbon particles broken, affecting the quality.

b. Storage: the product should be placed in a cool and dry place;in the transportation and use, to prevent water immersion;

c. To prevent tar substances: in the process of use, tar substances should be prohibited into the activated carbon bed that to plug the activated carbon gap, loses adsorption;

d. Fire prevention: activated carbon in storage or transportation, to prevent direct contact with fire, in case of fire; activated carbon after regeneration should avoid oxygen, the after regeneration`s activated carbon should be steam cooling to below 80 DEG C, or high temperature, with oxygen, activated carbon combustion.
