FAQ

Q: Can you accept sample order?
A: Yes, we accept samples with little and reasonable charge

Q: What is your MOQ?
A: Normally,4 rolls.

Q: The difference between the BMC and DMC DMC？: DMC is an ordinary premix molding compound with flame resistance and insulation. As continuously promotion, its social demand increases rapidly in United States. BMC has many different names.It mainly uses the polyester molding compound for production. Such great value and vitality of the new materials like BMC will play an increasingly important role in a wide range of areas. DMC is also known as the BMC. Although the development and application of BMC in China started late, it significantly promoted the industrial materials and technological progress. Because of their similar nature and process consistency, bulk molding compound such as DMC has the feature of leakage resistance and rigidity. especially the tensile strength of BMC which is based on unsaturated polyester. BMC refers to modified premix molding compound based on isophthalate polyester resin. With mass production and free coloring, it is irreplaceable for other raw materials. Bulk premix molding compund. In 1989, the development of everthing is inevitable.

Q: A chromic acid concentration and what kind of glass?reinforced?plastics should be used in chromic acid waste gas purification and recovery device.: Rated condition is 2. * filtering grid should be cleaned regularly according to the degree of pollution. * according to different air volume. There are two types including vertical network format and horizontal network format. * Airflow direction of horizontal recycle collector is from right into the left, and chromic acid waste gas purification recoverer is mainly used for recycling and purifying chromic acid waste gas from electroplate chromate tank belt. * the bottom must be maintained at a level of 5 meters. *Face velocity passed through recoverer filter net must be maintained at 2 to 3 meters per second so that chromic acid can be expelled from bottom hole with efficency is over 90% and chromic acid liquid is recycled. * All air duct system before the recoverer is made from plastic plate. The chromic acid can be directly poured into the plating bath with the airflow direction cannot be reversed. The airflow direction of vertical collector is from bottom to top and it should be used together with BF4-72 type centrifugal ventilation machine. It can be cleaned once a month.

Q: The difference between EPS and GRC, advantages and disadvantages, construction technology, key points, the scope of application.: Fissure is easy to leak water in the cold temperature. Flat connector does not absorb water with a little amount of coating and short production cycle (about 7-12 days). GRC decorative elements is heavy. Due to its shorter installation, it does not require very specialized workers. There is no problem under the temperature of plus or minus 50 degrees Celsius. It has excellent waterproof performance. It has pore and is not easy to chap, but it is easy to deal with and carry with good toughness. If you want to refit it, you need to do some waterproofing work. The connector can absorb water and the material used for producing is belongs to stiffness material with less crack. Finished products features with lightweight, crisp, poor uniformity. High-level job is difficult to process without leakage. Cracking phenomenon is serious and can be cut. Hot bridge is different to control with protective layer features with weathering resistance. Its weight account for 10% of the traditional non light components. Large deformation period is slow. It can be bended moderately. It features with freezing and?thawing resistance and little deformation. It is easy to install and crack so that it needs to be trimmed. It is easy to be linear deformation.

Q: Nominal interpretation of fiber reinforced concrete: Mix composite materials with random and uniform distribution of short fiber in cement concrete, including steel fiber reinforced concrete. Technical specification for fiber reinforced concrete structures CECS.

Q: What are the differences between glass fiber and asbestos?: Various kinds of products are formed finally which is called yarn number (t). The content of chrysotile is the most abundant. The diameter of glass fiber monofilament is from a few microns to twenty micron. 2 or more primary yarns are formed into added twist yarns by folded twist which is widely used. Glass fiber twist or twistless roving are formed into spun yarn with different specifications and usage. There mainly are alkali free. Composite line is formed by two or more fold twist. Glass fiber is a kind of inorganic nonmetal material with excellent performance. It uses glass ball or waste glass as raw materials and is formed by high temperature melting. It mainly is used for producing glass?fiber products. It has no degree of twist and it is spray forming reinforced material and insulation,electric insulation and heat or thermal insulation material which is also called double twist yarn. It mainly is used for hand lay-up glass?reinforced?plastics and is known as detwisting yarn in glass fiber industry. The meaning of metric system number. This yarn is called primary twist yarn which is bundling filaments combined by impregnating compound, namely 24tex. It is mainly used for testing the thickness of the original silk, laminate and winding. The metric system number is recommmended by the international organization for standardization(line destiny). 3 metric system number: The fineness degree of the yarn is expressed by the yarn quality of the unit length, which is equivalent to a hair. The smaller the number is, the thicker the yarn is. Monofilament is equal to 20tex. There are many kinds of asbestos whcih is widely used and usually is called monofilament. The former is a fixed length, the latter is a fixed weight.

Q: What is the material of glass steel? How to make it?: We mainly use glass fiber, and the adhesive is composed of unsaturated resin; curing agent, cyclohexanone; peroxide initiator, cobalt naphthenate (also used for the curing agent of benzoyl peroxide, initiator amine). The rate of solidation changes sharply with temperature, humidity and the curing to recipe. Roughly 100: 4: 1. There are processing winding machine to wind liner (tank shape) in axial and circumferential direction, soak it with adhesives before winding. According to the different liner, it is divided into two categories: Glass steel liner glass cloth paste and polyethylene liner polyethylene rotational molding.

Q: What equipment is needed for teating glass fiber twistless roving?: A universal tester and a muffle furnace is needed. glass culture dish is needed. One over ten-thousand balance Yarn metroscope. 2,One over ten thousand balance, blast stove, water content detection, oil (impregnating compound content).

Q: The difference among organic glass, glass steel and acrylic.: It is composed of methyl methacrylate monomer (MMA) polymerization, having the same life of the building. After a special process, the two kinds of composite organic glass acrylic (acrylic) can be compound, with the English name Acrylic. The extrusion can better control the thickness of the plate.
