The magnificence, charisma, and atmosphere of marble have attracted the attention of many homeowners. Many of the decoration owners have also chosen to use marble products. Many manufacturers have produced artificial marble with quality problems for their benefit. The hazards of this artificial marble are enormous. With the passage of time, do you find that you often lose hair? In fact, this is one of the hazards . What are the hazards of artificial marble ? Today we will come together to explore the harmful effects of artificial marble .

Artificial marble is good

Artificial marble is usually made of natural marble or gravel as a filler. It is made of cement, gypsum and unsaturated polyester resin. It is made by stirring, grinding and polishing, so artificial marble has many natural marbles. The characteristics, such as artificial marble, can be adjusted manually, so it has many colors, good flexibility, no obvious connection, and a very strong overall feeling. It is also colorful, with a ceramic luster, high surface hardness, hard to damage, corrosion resistance, High temperature, and very easy to clean.

But there is also a big drawback. It has significant damage to the human body. Currently, there are four types of artificial marble commonly found on the market: clay-type artificial marble, polyester-type artificial marble, composite artificial marble, and sintered artificial marble.

What are the hazards of artificial marble

1, a pungent chemical odor (especially in the processing process more odor), the color is not a natural chemical color, this type of artificial stone containing formaldehyde and benzene will produce a pungent odor when cutting, After the plate consumes and processes the molding device, excess formaldehyde and benzene remain. Formaldehyde and benzene will discontinuously volatilize within 3-5 years. Volatilization of benzene and formaldehyde and exposure to heavy metals will directly contaminate the imported food. This harmful substance not only enters the human respiratory system but also enters the digestive system directly. The level and speed of poisoning are more pronounced.

2. Because artificial marble is manufactured by man, it has many uncontrollable elements. In order to reduce costs, some manufacturers use inferior materials in the manufacturing process, apply harmful substances such as formaldehyde and benzene, and some even directly join in. Organic solvents, using heavy metal inferior materials, have produced a large number of "toxic marbles", and the damage of artificial marble is mainly reflected in the pollution produced by inferior materials.

How to choose artificial marble

1, see: Visual sample color is not pure turbidity, appearance no similar plastic gum texture, no fine pores on the back of the plate.

2, smell: nose smells no pungent chemical breath.

3, touch: hand touch the appearance of a sample of silk, no astringent, no obvious sense of ups and downs.

4, draw: use nails to draw sheet appearance, no obvious scratches.

5, touch: the same two samples hit each other, not broken.

6, check: Check whether the product has ISO quality system certification, quality inspection report, there is no production quality insurance card and related security signs.

Valves

Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.

People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.

In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.

Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.

More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
