Dyed quartzite A large number of dyed quartzites appear on markets and stalls, and are called "Malay Jade" and "Korean Jade". These names are used to confuse audition. The most common is the ring face, followed by the jade button and necklace. Identification focus: 1. The flashlight is irradiated from the side near the sample, and the granular structure can be seen with the naked eye. Zoom in to see the loofah structure. 2. The early dyed quartzite was reddish under the Charles filter, and now most of it does not change color. This identification result is for reference only. Stained glass Imitation jade glass has a long history and is often referred to as "materials" and "stones" in the industry.

FAQ
Q : Whats the classification of Flame Retardant Fabric?
A : --Disposable FR fabrics
--Chemical treated FR fabrics
--Inherently FR fabrics
Q : What is the difference between fire retardant and fire resistance?
A: A fire retardant material slows burning across the surface of a combustible substrate. A fire resistive material delays heat penetration through a substrate.
Q: How to ensure your product quality?
A: Xinke protective has wholesome and updated test facilities, Test center has picture and more details. And we can provide the certificates you need.
Q: How to ensure your the delivery time?
A: We have advanced and environmental production line with experienced workers to ensure product delivery time between 20-30 day. And we have running protective fabrics only need 15-20 days. For
example, 330g cotton fr fabric and 7oz cotton nylon fr fabric.
Q:Whats the difference between Inherent Flame Resistance and Treatments?
A:Inherently flame resistant fibers contain an essential characteristic that protects the wearer from an ignition source.Treatments or treated fibers have an applied chemical treatment that changes the original level of flame resistance.Flame resistant garments are generally made from either flame resistant materials such as those made from aramid fibers, melamine fibers, or those treated with flame resistant "FR" treatments such as Ammonia or Heat Cure . FR treatments can Wash Out over time, shorting thelife of the garment.
Q:How do normal fabrics react to ignition?
A:Normal fabrics and garments will burn away from the point of ignition with an increasing rate of flame spread and continue to burn after removal of the ignition source. Normal fabrics will continue to burn until they are extinguished or all flammable material is consumed.
Q:What is the best FR fiber or fabric?
A:There is no perfect flame-resistant fabric system that meets all needs. Each FR fiber or treated fabric has certain properties that, depending on end use requirements,can be either benefits or shortcomings. Blending different fibers attempts to balance these properties for maximum fabric performance.
Q:Is 100% cotton flame resistant?
A:No. In most cases, 100% cotton is flammable. It can ignite and continue to burn after being exposed to an ignition source. Many people understand the burning and melting hazards of nylon and polyester fabrics, but fail to recognize the danger of wearing 100% cotton when exposed to an ignition source. However, cotton can be a good fabric to wear underneath proper FR clothing.

A:No. If you "over specify" by requesting a standard that is higher than necessary, you may end up over treating your fabrics and that can cause problems. Specify only the code that is required.
