(3) If the impeller or the inlet and outlet water pipe is blocked, the impeller or pipe can be cleaned, and if the impeller is seriously worn, it should be replaced. If the filler mouth leaks, press the filler. If the conveying height is too high or the tube loss resistance is too large, the conveying height should be reduced or the resistance reduced.
The horizontal slurry pump should be used for regular maintenance. This can effectively avoid the problem of slurry pump blockage, and if you encounter these problems in the process of using slurry pump in the later stage, you can solve them according to the above steps.

Quality control is a cornerstone of the manufacturing process in rubber slurry pump factories. Each pump undergoes rigorous testing to assess its performance under various conditions. This includes pressure tests, flow tests, and wear tests, simulating real-world operating environments. Factories use specialized equipment to measure parameters such as flow rates and pressure drops, ensuring that each pump performs to the required specifications.

  • As early as sixty years ago, zinc sulphide was first thought of as a pigment for coloring India rubber and a patent for the process of its manufacture was issued in England. But it was not until twenty years later that zinc sulphide and its manufacture was seriously considered as a pigment for paint, and in 1874 a patent was issued for a process of manufacturing a white pigment, composed of zinc sulphide and barium sulphate, known as Charlton white, also as Orr's white enamel. This was followed in 1876 by a patent issued to a manufacturer named Griffith and the product, which was similar in character to Charlton white, was known as Griffith's patent zinc white. In 1879 another patent for a more novel process was obtained by Griffith & Cawley, the product made under this process proving the best of the series placed upon the market up to that date. After that time many new processes were patented, all, however, tending to the same object, that of producing a white pigment, composed of zinc sulphide and barium carbonate, the results, however, in many cases ending with failure.

  • Titanium is a common metal element frequently found throughout nature. In our environment, titanium is naturally exposed to oxygen, forming titanium oxides that we find in many minerals, dusts, sands, and soils.

  • Close to sample
  • In the realm of industrial coatings, the quality of the end product is often determined by the materials used in its creation. One such material that plays a crucial role in achieving high-quality coatings is titanium dioxide, specifically in its rutile form. This pigment is prized for its excellent whiteness, which not only enhances the aesthetic appeal of coatings but also contributes to their overall performance.
  • Familiarise yourself with the Regulation and its requirements
  • One of the primary advantages of lithopone is its cost-effectiveness compared to other white pigments like titanium dioxidelithopone zns-baso4 supplier. Its lower price point, coupled with its comparable performance, has made it a popular choice for many manufacturers looking to optimize their production costs without compromising on quality. Furthermore, its non-toxic nature and environmental friendliness have contributed to its increasing popularity, especially in eco-conscious markets.



  • Pure PVB is non-toxic and harmless to human body. In addition, ethyl acetate or alcohol can be used as solvent, so PVB is widely used in printing ink of food containers and plastic packaging in European and American countries.

    Storage safety properties

    PVB can be stored for two years without affecting its quality as long as it is not in direct contact with water; PVB shall be stored in a dry and cool place and avoid direct sunlight. Heavy pressure shall be avoided during PVB storage.

    Solubility

    PVB is soluble in alcohol, ketone, ester and other solvents. The solubility of various solvents changes according to the functional group composition of PVB itself. Generally speaking, alcohol solvents are soluble, but methanol is more insoluble for those with high acetal groups; The higher the acetal group, the easier it is to dissolve in ketone solvents and ester solvents;

    PVB is easily soluble in cellosolve solvents; PVB is only partially dissolved in aromatic solvents such as xylene and toluene; PVB is insoluble in hydrocarbon solvents.

    Viscosity characteristics of PVB solution

    The viscosity of PVB solution is greatly affected by the formula of solvent and the type of solvent; Generally speaking, if alcohol is used as solvent, the higher the molecular weight of alcohol, the higher the viscosity of PVB solution;

    Aromatic solvents such as xylene and toluene and hydrocarbon solvents can be used as diluents to reduce the viscosity of PVB solution; The effect of PVB chemical composition on viscosity is summarized as follows: under the same solvent and the same content of each base, the higher the degree of polymerization, the higher the solution viscosity; Under the same solvent and the same degree of polymerization, the higher the acetal group or acetate group, the lower the solution viscosity.

    Dissolution method of PVB

    Where mixed solvents are used, the dissolution step is to first put aromatic solvents (such as xylene, toluene, etc.) or ester solvents (such as n-butyl acetate, ethyl acetate, etc.) into the mixing, slowly put PVB into the mixing, and then add alcohol solvents (such as n-butanol, ethanol, etc.) after PVB is dispersed and expanded,

    At this time, the dissolution time can be shortened by heating; Using this dissolution method, the formation of lumpy PVB can be avoided (because the dissolution time will be several times after the formation of lumpy PVB), so the dissolution speed can be accelerated. Generally, the ratio of aromatic and alcohol solvents is 60 / 40 ~ 40 / 60 (weight ratio), and PVB solution with low viscosity can be prepared.

    The solvent composition contains 2 ~ 3wt% water, which can improve the hydrogen bonding strength of alcohol solvents and help the solubility of PVB.

    Processing properties

    Although PVB resin is a thermoplastic, it has little processability before plasticizer is added. Once plasticizer is added, its processability is very easy.

    The purpose of general coatings and adhesives is to change the resin characteristics by adding plasticizers to meet the application requirements, such as film softness, reducing the TG point of the resin, reducing the heat sealing temperature, maintaining low-temperature softness, etc.

    Compatibility

    PVB can be compatible with a variety of resins, such as phenolic resin, epoxy resin, alkyd resin and     MELAMINE resin.

    B-08sy, b-06sy and b-05sy with high acetal degree can be mixed with nitrocellulose in any proportion. PVB and alkyd resin are partially compatible. General PVB is compatible with low molecular weight epoxy resin, while high molecular weight epoxy resin needs PVB with high acetal degree to be compatible with each other.
