The primary function of a drainage pump is to collect and remove water from a specified area. Most commonly used in basements, crawl spaces, and construction sites, these pumps are equipped with a float switch that activates the pump when water reaches a certain level. Once the water is detected, the pump will turn on, drawing the water into its casing and expelling it through a discharge pipe to a designated drainage area. This process continues until the water level drops below the float switch, at which point the pump turns off.

  • 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.

  • Wholesale yellow oxide quotes typically vary based on the quantity purchased, quality of the product, and the supplier's location. Large-scale buyers often negotiate better prices due to economies of scale, while premium quality oxide might command a higher price. Additionally, transportation costs and import/export tariffs also contribute to the final quote.

  • Solids were stable and did not show visible signs or changes in their spectra after being kept at room temperature for over 60 days. The absorbance at the maximum absorbance wavelength remained unmodified.

  • Apart from its use in pigments and additives, titanium dioxide is also employed in the production of other chemicals

  • Animal studies show exposure to titanium dioxide is linked to immunotoxicity, inflammation and neurotoxicity. 

  • New adjustments have been announced for tariff rates, which will benefit the chemical industry in China in particular, due to decreased import and export tariffs for several chemicals. The export tariff for ilmenite will stay unchanged by 10% and the rate for ferrotitanium decreased by 5% down to 20%.

  • Another common use of titanium IV oxide is in food coloring. Titanium dioxide is a FDA-approved food additive that is used to enhance the color of various food products. It is commonly used in candies, pastries, and dairy products to create vibrant colors. Titanium dioxide is a safe food additive that is used in small quantities to enhance the visual appeal of food products.
