    China Paint Online News Information:
    winter is coming, cold and warm is not only more clothes, home heating work is also essential. Wall insulation is an important part of home insulation work, divided into external wall insulation and internal wall insulation two kinds, the amount of internal wall insulation works than the external wall insulation is much smaller. The advantages and disadvantages of various interior wall insulation materials.styrene foam plate(see all pictures online of Chinese coatings)
    polystyrene foam plate is one of the three common internal wall insulation materials. Also known as foam plate, EPS plate, is a volatile polystyrene bead containing volatile liquid foaming agent after heating pre-eject, heated into a white object in the mold. It has the structural characteristics of fine closed holes, mainly used for building walls, roof insulation, composite board insulation and so on. It is divided into expansion EPS board (benzene plate) and continuous extrusion XPS plate (extruded plate).advantages:
    1, polystyrene foam plate density coefficient is small, good impact resistance, sufficient ability to change and reply to the shape of the external impact force buffer;
    2, with an independent bubble structure, small area of damage will not affect the entire wall;
    3, its surface water absorption rate is low, anti-penetration performance is good, reflective thermal insulation coating can effectively avoid the wall after moisture mold, shedding and other wall problems;shortcomings:
    1, construction needs to hang the net, construction process cumbersome, long duration;
    2, flammable, toxic gas after combustion. Ordinary polystyrene foam insulation plate is easy to burn, combustion smoke is toxic, even after the addition of flame retardant, combustion can only reach class B;
    3, material strength is poor, easy to crack phenomenon, insulation layer shedding phenomenon is more common
    4, polystyrene foam insulation plate due to its own limited strength, poor load capacity, patch brick needs to be strengthened treatment;
    5, polystyrene foam insulation plate quality is unstable, because the material needs to be placed for a period of time, after a period of maturity can be used, if not mature thoroughly, quality will not be guaranteed, resulting in foam plate cracking.polyurethane foam
    (see china paint online full picture news)
    polyurethane foam is also one of the three common inner wall insulation materials. It is a special polyurethane product that fills the polyurethane pre-polyester, foaming agent, catalyst, etc. in a pressure-resistant aerosol tank. When the material is equiped from the aerosol tank, the mothy polyurethane material expands rapidly and forms a foaming reaction with water in the air or the substrate in contact with it.
    after curing foam with fill, bonding, sealing, insulation, sound absorption and other effects, is an environmental protection and energy-saving, easy to use building materials. But it is also a highly flammable substance.advantages:
    1, good insulation performance. Low thermal conductivity is a better material for building insulation
    ; Foam holes are closed, closed rate of 95%, rainwater will not seep through the holes
    3, due to site spraying, the formation of an overall waterproof layer, no seams, any polymer coils are not enough to reduce maintenance work;shortcomings:
    1, temperature below 10 degrees C, polyurethane foam rate will be reduced. Therefore, when using obviously by the season constraints
    2, polyurethane foam spray molding speed, want to make a flat spray effect is not easy, uneven is a normal phenomenon;
    3, used for roof waterproof insulation, flatness can be relaxed, but the eaves, trench flatness is not good, will affect the drainage flow rate. Therefore, it should be used in conjunction with other waterproof materials.fiberglass insulation cotton
    (see all pictures on China Paints Online News)
    fiberglass cotton is an inormeric non-metallic material with excellent performance and is one of the three common internal wall insulation materials. Glass ball or waste glass as raw materials, by high-temperature melting, wire, yarn, weaving and other processes manufactured, the diameter of its single wire for a few microns to twenty meters microns, equivalent to a hair wire 1/20-1/5, each bunch of fiber raw silk is composed of hundreds or even thousands of single silk.
    fiber insulation cotton has good insulation, strong insulation, good sound absorption effect, long fiber, high anti-pull performance. Widely used in building air-conditioning insulation systems, decorative wall sound insulation, decorative ceilings, as well as chemical, power and other industries equipment insulation.advantages:
    1, good insulation. Fiberglass cotton has numerous small gas holes, fiber appears irregularly arranged,
    is an excellent insulation material; Fiberglass cotton will not burn, no deformation, no brittle, can withstand 700 degrees of high temperature, its combustion
    performance reached A1 level; Because fiberglass cotton in the manufacturing process does not add any adhesive, so there is no smell, when high temperature will not emit
    toxic, pungent smell, smell,
    etc. ; Long-term use can easily lead to damage, once there are sharp objects scratched on the surface, will cause irretrigable wear.Interior Wall Insulation Coatings

    Interior Wall Insulation Coatings
    Reflective Insulation Coatings is a new type of insulation material, is a kind of space energy-saving insulation coatings (space energy-saving insulation coatings including warm-up and high-temperature types), is to prevent heat transmission coatings. Reflective thermal insulation coating single-part modified inorance water-based paint, temperature resistance is divided into temperature-resistant 150 degrees C, bone white thick slurry, solid content of more than 85%.
    reflective insulation coating curing proportion of only 0.46g/ml, with energy-efficient thin layer, thermal insulation, decorative waterproof and mold-resistant, fireproof and anti-corrosion, insulation in one of the new space energy-saving reflective thermal insulation coating. The construction method of reflective insulation coating inner wall insulation coating is similar to that of general wall coating. Add a moderate amount of water stirred into a paste and then directly applied to the treated wall, after two application press light, completely dry after brushing glue, sticky glass brazing mesh tape, after which you can paint the wall work.advantages:
    1, reflective thermal insulation coating light quality, do not occupy space area, thin thickness, small thermal conductivity, can be insulable cold and insulation, but also able to shock-absorbing sound;
    2, reflective insulation coating can be arbitrarily cropped, according to the type of support, non-toxic environmental protection does not pollute the environment, do not stimulate the skin;
    3, reflective insulation coating construction loss-free, easy construction, low volume density, cost-effective;disadvantages:
    may produce telescopic cracks. The outer wall due to day and night and seasonal changes, by the outdoor temperature and solar radiation and the impact of swelling, when the indoor and outdoor temperature difference is too large, the internal and external wall will shrink changes, this repeated change, so that the wall is always in an unstable state, may produce cracks. And the inner wall is basically not affected by this, can be used as a good inner wall insulation material.
