Key Benefits

3. Sound Insulation Gypsum tiles offer excellent sound insulation, making them an ideal choice for spaces that require noise reduction, such as recording studios, offices, or residential homes. They help in dampening sound transmission between rooms, enhancing privacy and comfort.

Mineral fiber ceiling tiles are a popular choice in both commercial and residential spaces due to their acoustic performance, fire resistance, and aesthetic appeal. These tiles are primarily composed of materials derived from natural or synthetic minerals, which contribute to their advantageous properties. Understanding what these tiles are made of can help consumers make informed decisions when selecting ceiling products for their buildings.

One of the standout features of mineral fibre board ceilings is their exceptional acoustical performance. These boards are engineered to absorb sound, which minimizes echoes and enhances speech clarity within a room. This is particularly beneficial in commercial spaces such as offices, restaurants, and auditoriums, where noise control is essential for creating a comfortable environment. By incorporating mineral fibre boards, designers can achieve a balance between aesthetic appeal and functional acoustics.

HVAC access panels in ceilings are invaluable for maintaining efficient and safe heating and cooling systems. By providing convenient access for inspections, repairs, and cleaning, these panels contribute significantly to better indoor air quality, energy efficiency, and overall system performance. Whether you are a homeowner or a business owner, understanding the importance of these access points is crucial for ensuring that your HVAC system operates at its best. Investing in the right access panels and their proper installation can lead to long-term savings and a healthier living or working environment. So, make sure to consider the role of HVAC access panels when planning your next HVAC maintenance or installation project.

  • 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.
