First, household invisible killer floor formaldehyde exceeds health hazards
In the incident, the net test report provided by the net user's Anxin floor test showed that the formaldehyde emission of the E0-class solid wood composite floor of Anxin was as high as 2.5mg/L, and the formaldehyde emission standard of the national-designated E0-class environmental floor was 0.5mg/L. More than 5 times the standard.
The main source of formaldehyde in homes is flooring, furniture, and decorative wood. The maximum allowable formaldehyde concentration in the family room is 0.08 mg/m3. The amount of formaldehyde released from the solid wood flooring laid at home far exceeds the national standard value, and the indoor formaldehyde concentration increases. When the maximum allowable value is exceeded, the human body will have a sense of discomfort, and there will be pharyngitis, asthma, headache, nausea, etc. Symptoms, severe can cause chest tightness, wheezing, and even death.
Second, consumers carefully purchase "problem floor" four major issues need attention
The letter “The floor of problems†reminded us that the prevention of formaldehyde pollution at home must be started with the purchase of parquet.
1, recognize three no goods
When you purchase the floor, you should recognize the brand logo of the product, pay attention to the name and address of the manufacturer, and avoid purchasing three products. Some small businesses tend to shoddy, and floors with excessive levels of formaldehyde pretend to be environmentally friendly. It is imperative to choose strong companies when buying.
2, see the environmental protection signs
When purchasing environmentally friendly flooring, it is important to see if there is an eco-friendly sign on the floor. Imported floors generally have international environmental protection signs and blue sky patterns, while domestically produced floors have the Seven-ring Logo of the China Environmental Labelling Product Committee (CCEL).
3, smell discrimination products
Brands such as Anxin flooring, all signs are complete. When we purchase, we must also carefully check whether the floor formaldehyde emission is excessive. It is desirable to take a section of solid wood flooring and carefully smell it. If there is a pungent smell or feels glare, the product is definitely a product with unqualified formaldehyde emission.
4, soak test authenticity
When purchasing, you can take a small piece of the top of the template and soak it in boiling water for 1 to 3 minutes to see if there is a pungent odor. If the irritating odor is strong, proving that there is more free formaldehyde in the floor substrate, the product is most likely not in compliance with national environmental standards.
III. Vanke Incident Warning New Formaldehyde Inspection Cannot Be Ignored
The example of Vanke's fully-furnished room using formaldehyde-exceeding flooring tells us that whether it is the acceptance of a house or the inspection and acceptance of a house, we must pay attention to the formaldehyde content in the room.
1, formaldehyde detection test paper
Formaldehyde detection test paper can be used for simple determination of household formaldehyde. The space to be tested shall be sealed for more than 1 hour. One drop of test solution (10-20 μl) shall be dropped on the test paper, and the excess liquid shall be aspirated. The test paper shall be placed in closed air for 10 minutes. After comparison, the color card shall be used for comparison. Remove formaldehyde from the air.
2, self-test box test
Another simple method for detecting the formaldehyde content in a room is the self-test box test. Before the test, turn off the room for 8 hours, then pour the tested reagents into Reagent No. 2, shake and dissolve, pour into the absorption box, place it at 0.8~1.5 meters for 40 minutes, add reagent No. 3, and let stand for 10 minutes. Card readings can be.
Fourth, the use of goods in addition to formaldehyde to help you purify the indoor air
Formaldehyde is a colorless gas with a strong pungent odor. Formaldehyde has stimulant, sensitization, and carcinogenic effects on the human body. A small amount of formaldehyde gas remaining after general interior decoration can be adsorbed by some plants and articles to remove formaldehyde.
1, activated carbon adsorption method
Activated carbon has adsorption capability for benzene, toluene, xylene, ethanol, ether, kerosene, gasoline, styrene, vinyl chloride and other substances. Activated carbon bags can be placed in newly renovated rooms. Adsorption of formaldehyde from the air by activated carbon is a convenient and cost-effective method.
2, plant absorption method
Plants can absorb carbon dioxide and release oxygen. Plants such as spider plants, aloe vera, and tiger-tailed orchids can absorb indoor formaldehyde and other pollutants and release fresh oxygen. The newly renovated houses display plants that can remove a small amount of formaldehyde in the room and keep the indoor air fresh. This is a low-carbon, environmentally friendly method.

CPVC Resin made by polyvinyl chloride( PVC) resin chlorinated modified system. Appearance is white or light yellow, tasteless, non-toxic loose grain or powder.
Characters:
I. Widely used range---Vicat Softening Point than PVC increases by 40℃, one of polymer can be used in high temperature and high pressure for long time;
II. Mechanics performance---tensile strength than PVC increases by 50%, 1 time increases than ABS resin, PP resin, CPVC could still maintain in a strong rigidity, fully meet at this temperature to the requirements of the equipment and pipeline especially close to 100℃;
III. Chemical corrosion resistance---CPVC not only has chemical corrosion resistance in room temperature, but also has good acid and alkali resistance at higher temperature, far better than PVC and other resin, it can replace the traditional material to handle corrosive substance;
IV. Good fire-resistance---CPVC with good self-extinguishing feature, the limiting oxygen index is 60, no form drop, limit flame spread and smoke generation;
V. Low co-efficient of heat conductivity---the heat conductivity of CPVC is 0.105KW/(mk), the CPVC heat-resisting pipes are with less heat loss and the heat insulating layer is unnecessary;
VI. The CPVC will not be affected by the chlorine left in water--Polyolefin Material( such as PP/PE) will decompose when they meet the chlorine left in the water, will not have crack or drip;
VII. The bacteria will not easy to breed---because the CPVC pipe will not be affected by the chlorine left in water, and also can resist the common sterilization chemicals;
VIII. It's same with PVC when processing---the processing way of CPVC finished products is same with PVC product, it's very easy and convenient.
