Q:What are the specific national standards for pvc? The

To be specific, it is pipe or pipe. A lot of types, to check the net job

Q:What are the hospital wall decoration materials?

In fact, antibacterial, mildew material is necessary. Otherwise there will be a lot of problems. EPA certified products are safe.

Q:PVC crust foam board business standards or national standards

Received, PVC crust foam of the enterprise standard can not send me a ah? I also find the national standard did not.

Q:Bathroom cabinet pvc plate is solid wood particles board it

PVC board is a plastic plate, not a solid wood board

Q:Does the steel pvc board have radiation?

No ah But now are using integrated ceiling, is the aluminum plate, PVC are out of date.

Q:PVC board and EVA board What is the difference, which is good flexibility

PVC is a hard foam board similar to a foam board. Buy the PVC board when the attention to thickness and density, the thicker the greater the density the more expensive. There is also a material called EVA COS props used in more soft and easy to plastic but not convenient color and carved pattern. EVA has good flexibility

Q:Blister and PVC board distinction. Detailed description of the best.

Blister board is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastics, with excellent physical and mechanical properties, especially excellent impact resistance, tensile strength, bending strength, compressive strength High stability, low stability, good heat resistance and low temperature resistance, in a wide temperature range with a stable mechanical properties, dimensional stability, electrical properties and flame retardant, can be in -60 ~ Long-term use at 120 ℃; no significant melting point, melting at 220-230 ℃ state; due to the large molecular chain, resin melt viscosity; small water absorption, small shrinkage, high dimensional accuracy, good dimensional stability, Oil resistance, but not resistant to ultraviolet light, good weather resistance; oil, acid, intolerant alkali, oxidizing acid and amine, ketones, soluble in chlorinated hydrocarbons and aromatic Solvent, long-term in water easily lead to hydrolysis and cracking, the disadvantage is due to poor fatigue strength, prone to stress cracking, solvent resistance is poor, poor wear resistance. PVC board is PVC as raw material made of cross-section for the honeycomb mesh structure of the plate, is a vacuum plastic film. For all types of panel surface packaging, it is also known as decorative film, with film, used in building materials, packaging, medicine and many other industries. Which accounted for the largest proportion of building materials industry, 60%, followed by the packaging industry, there are several other small-scale application of the industry. According to the degree of soft and hard can be divided into soft PVC and hard PVC, according to the production process can be divided into PVC leather foam and PVC free foam board. General performance PVC resin is a white or light yellow powder, the relative density of 1.35-1.45. The softness of the product can be achieved by adding

Q:Pvc floor green? Can you pave it in the bedroom?

First, the plastic floor can not be used outdoors. The reason for using in public places is not because the floor is not environmentally friendly, but the plastic floor is more wearable. Secondly, in terms of environmental protection, some domestic flooring, although the environmental protection standards of Europe and the United States, but more environmentally friendly than to strengthen is sure. The golden mouse floor is nice. If the economic strength to allow, then choose to import better.

Q:PVC sheet with formaldehyde?

More or less will be some formaldehyde, the plate made of furniture can be used liquid Maya blue is the main component of the extraction of hydroxypropylated derivatives in plants, through complexation, condensation, addition reaction, rapid capture of benzene, ammonia Compounds, mercapto compounds, formaldehyde, TVOC and other volatile compounds with odor. Sprayed on the surface of the furniture, the formation of a layer of colorless, tasteless, transparent film, it can have α-hydrogen atoms and aldehydes, weak base or weak acid under the effect of condensation from β-hydroxy aldehydes or ketones Further polymerized into macromolecules nonvolatile compounds, no longer volatile into the air, so as to achieve the principle of removal of harmful substances.

Q:The building codes where I live are based on NEC codes. They're really hard to understand as a non-electrician.

Yes, PVC conduit will be fine, unless you're in a commercial or industrial application. Be sure to use grey PVC, although it costs a bit more. If you use white, some poor schlub (maybe me) will come along someday and cut through it thinking it's water (we always use white for water, yellow for gas, and grey for electricity).
