7. Can be processed like wood drilling, sawing, nailing, planing, sticky processing
8. suitable for hot forming, heat bending and folding process
9. According to be welded, it can be bonded with other PVC materials
10. The surface is smooth, printable

Formaldehyde and benzene harm to human body

The difference between common formaldehyde and benzene is carcinogenic gases are harmful to human beings, but they have a lot of essential difference.

Formaldehyde is a colorless, odorless gas, latent in viscose, density board, furniture and other decoration materials and furniture inside.

Human beings affected by formaldehyde pollution manifested as skin allergies, dazzling pungent, throat dry cough and so on. Long-term exposure can cause chronic respiratory disease, lead to nasopharyngeal cancer, colon cancer, brain tumor, menstrual disorders, mutations nucleus, within the DNA single-strand DNA cross-linking and cross-linking with proteins and inhibit the repair of DNA damage, pregnancy syndrome, cause neonatal chromosomal abnormalities, leukemia, causing adolescent memory and mental decline.

Benzene is a gas with a strong fragrance, hidden in the paint, wood, wallpaper, adhesives and other decoration materials and furniture inside, so there benzene gas release, people can feel the smell, the performance of the human body due to benzene contamination headache, nausea, vomiting, blurred consciousness, loss of consciousness, coma, convulsions, long-term exposure will cause great harm to the blood, causing chronic poisoning, causing leukemia.

Treatment:

long-term treatment, it is recommended to use ventilation and adsorption plants. Suitable for decoration not in a hurry after the check-in customers.

Short-term treatment, recommended decoration pollution control, and then purchase the right amount of plants were placed indoor (deprecated activated carbon, carbon functions not as green plants and long-term, but also beautify the environment and plant), after preliminary check often maintain good indoor ventilation.

Another better approach is from the source to prevent ,to use new materials, wood-plastic composite material, (WPC). It made of polyethylene and wood flour as raw materials , non-toxic, environmentally friendly, 0 formaldehyde. Cutlery in hospitals and catering in infusion bags are produced with this material, we can say truly environmentally friendly flooring.

You need to know while installing WPC material

Most of the wood fiber content in WPC products is greater than 50%. this material also played some aliases, such as severe tension “waterproof wood”, “green wood” and other global timber resources for wood floor to provide a broad space for development. “The following precautions during installation wood materials should be done.

First, with regard to cutting and drilling wood materials, some tips while using alloy saw and drill: thin tooth blade (such as 45 cm in diameter, 18-24 tooth) cutting easier, unlike wood, WPC is easier to be drilled, and you do not have to consider the use of WPC wood grain direction or nodes.

When drilling deeper or larger holes, to be exit debris yourself, do not always want disposable drilled.
Second, while installating, under normal circumstances, the WPC joists gap is 30-50 cm (depending on the size of the profile).

Self-tapping screws is the preferred installation profiles.

When using special screws to install, you must pre-drilling. Pre-drilling diameter should be less than 3/4 straight nail or screw diameter.

When the profile is wider than 10mm, each end should be two screws.

Third, the gap between wpc materials should be taken into account when installing the drainage, cleaning, and a slight thermal expansion or contraction and other reasons, when the bar is mounted, side to side, must leave adequate clearance between the head.

Edge to Edge: WPC side to side between the requirements of ≥4 mm: When installed in a cold climate, ≥4 mm clearance requirements.

Head to head: the gap between the WPC head to head size depends on the length of the profiles, the temperature during installation, the thermal expansion coefficient profiles (ζ≈0.9 × 10-4), as well as local highest possible temperature.

Head to head clearance calculation method:

For a L-meter-long sections, local maximum possible temperature within a year of Tmax, the temperature of the installation is T, then install the root profile head should be retained gap Δ L = ζ × (Tmax? -T) × L.

For example: a 2 m long profile, installation day temperature of 10 ℃, the hottest day of the year the temperature is 40 ℃, then when the root sections installed head clearance should be retained:

Δ L = ζ × (Tmax- T?) × L = 2000 × (40-10) × 0.9 × Note: You must ensure proper clearance when WPC installed and mounted directly on the joists. Do not WPC fixed directly on any solid surface, such as concrete, roofing or roof and so on.

(1) WPC railing when used, must be lined with steel or steel, and the same floor to be absolutely firm, railing lining column spacing requirements per 450mm, to prevent deformation fall.

(2) Wood for the pavilion or flower time, to consider the thermal expansion coefficient, and the columns and beams absolute must lined pipe, and vertical to be securely connected.

(3)WPC has certain characteristics of plastic, so that when the length is greater than three meters, the material has a certain degree of bending, easily corrected to normal installation. If the wood is a cross-sectional profile, its bending deformation is relatively increased. Installation is able to basically correct place.

(4) When the profile is installed upright, and a length greater than 3 m, each end use four pairs of clamp screws.

The main construction methods WPC furniture

WPC Furniture Board and other connections used in wood in these areas, the main subject is a dynamic load, and connections are tongue and groove snap, mechanical connections, gluing, welding.

They stand snap in a manner similar to furniture tenon joints, mortise slot when inserted into the tenon splicing, the two parts together, snap mode can be well fixed two WPC, solid structure, but generally when combined with an additional office in successive gluing or nailing to enhance the overall strength of the connection.

Mechanical connection generally refers to the use of screws, bolts and rivets and other fasteners to connect two separate sections or parts into a process of complex parts or components

Bonding means connecting end impose sticky agent, to produce a certain focus and play rubber ligation way.

LeadWPC Participated in DOMOTEX 2016 in Hannover Germany Successfully.

From January 16th to 19th 2016, LeadWPC attended DOMOTEX 2016 Hannover International Flooring Coverings Fair.

Founded in 1989, DOMOTEX in Hannover is the world leading trade fair for carpet and floor coverings, which is also one of the leading professional international exhibition floor coverings. LeadWPC expands European market and gets the latest information through communication during DOMOTEX, meanwhile set itself a good image of high quality wood plastic composite decking in front of European market.

DOMOTEX attracted 1,441 exhibitors from 59 countries and 45,000 trade visitors from more than 100 nations. The products we exhibited include outdoor decking, outdoor co-extrusion decking, indoor flooring, board for furniture, wall cladding. During the exhibition, potential clients from local Germany construction companies, landscape design and building materials shops and even some building material related business visited our LeadWPC booth, consulted some information including production technics, product quality, price, installation and warranty.
For several senior clients, with their continual trust and encouragement on LeadWPC, after they confirmed our sample, they signed a contract with us immediately. Moreover, new customers showed a strong interest towards LeadWPC products after they visited our booth, and even some took samples for testing with our elaborate analysis of our product and quality. LeadWPC products and company capability impress them to a large extent.

Our company LeadWPC will adhere to the concept of sustainable development and develop low-carbon wood and plastic composite new materials with innovative ideas.
