Q:What are gypsum powder reinforced resins?
(lightweight high-strength foam gypsum handicraft, weight ratio), gypsum powder 89-99%, rubber polymer latex 2.8, starch 0.5-5, surfactant 0.1~0.2. Dosage of water and gypsum; latex foaming agent 0.1~0.2; preparation and use; dissolve additives in water; then mix with gypsum powder to make.
Q:Lightning protection with a TV antenna?
It baffles me as well but I think the reason is that if he resigns then Bush Cheney would have to admit failure and they'd rather have Laura Barney as their only supporters than to admit the truth. When you have top military personnel talking resignation we'd better be listening
Q:What kind of material is the resin made of?
Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
Q:What's the difference between type 5 resin powder and type 8 resin powder?
SG-8 type resin, reaction temperature and pressure has basically reached the polymerizer working pressure limit, the reaction requires relatively harsh conditions, more strict operation, safety, technology, personnel quality and other aspects of the requirements, and it is more difficult to control the quality of resin.Use:SG5 (K-65, S1000): pipes, profiles, plates and so on;SG3 (K-70, S1300): mostly soft products, hoses, wires, cables, films, shoes, toys, auto parts;SG7, SG8 (K-60, S800, S700): pipe fittings, sheets, containers, etc..
Q:How can the resin lenses be repaired?
Although the surface of resin lenses specially hardened, but compared to glass or slightly inferior, so to avoid friction and hard material. Try not to wear it while swimming at the beach.
Q:Another fire alarm issue?
:) I have never had to decide that as i have never seen an out of order fire hydrant. Call and ask the fire dept. they will enjoy the challenge. :)
Q:What are synthetic resin curtain wall decorative coatings?
A class of polymers synthesized by artificial synthesis. A viscous liquid or heating softening solid, usually heated or softened at a temperature range that exhibits a plastic flow under external forces. Some properties are similar to those of natural resins. The most important use of synthetic resins is to make plastics. In order to facilitate the processing and improve the performance, often add additives, and sometimes also used directly for processing forming, it is often synonymous with plastic. Synthetic resin or synthetic fiber, paint, adhesives, insulation materials and other basic materials
Q:What is the difference between acrylic and resin?
Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials.
Q:Why multistage dilution is used in the later production process of resin?
The NL curing agent has low toxicity and basically no irritation. The resin is cured with high strength and good corrosion resistance. It is easy to use and easy to use and has a long storage period. This product is suitable for curing thermosetting phenolic resin and furan resin at room temperature. Used to prepare phenolic resin and furan cement; glass fiber reinforced plastic products; bonding of pens, brushes, bamboo and wood products; also used as a room temperature curing agent for casting resins. The quality index of appearance of dark grey liquid relative density (20 C) 1.16 + 0.01 (viscosity coating -4,25 C). 20 - 30 of total acidity (H2SO4)%18 + 2 free acid (H2SO4)%3 5 storage period for more than one year (closed storage) application of phenolic resin and furan resin, the amount of NL the curing agent is generally in the range 512%. When the ambient temperature is 20 degrees centigrade, the dosage of NL curing agent of 2130 phenolic resin is about 8%, and the dosage of NL curing agent can be adjusted with the temperature.
Q:What is resin synthetic leather?
It is in the textile or non-woven cloth base, by a variety of different formulations of PVC and PU foam or film processing, according to the different strength and color, gloss and pattern processing requirements made with variety of colors, good waterproof performance, neat appearance, high utilization rate and the price is relatively cheap leather but the vast majority of features, artificial leather, leather can not reach the handle and elastic effect; longitudinal section of it, we can see artificial fiber film fine bubbles, or the surface of the cloth and dry dry.
