When decorating, many people will consider whether to buy a door or do a door? In general, if the decoration style is simple and you want to finish the decoration as soon as possible, it is best to buy a door; if your homework is more live, on the door style The requirements are relatively large, and you can consider making doors by hand. However, if you have a lot of woodworking, you should also consider environmental issues. Quality comparison Due to the quality, paint effect and environmental protection of the wooden doors, these aspects are much higher than the manual door. In general, brand-name wooden doors have relatively large-scale production machinery and equipment, which are mature in the dryness, finger joints, flatness and paint lines of the wood, but the production plants of the door have a rigid place in style and color. . Handmade wooden doors and sets are mostly made of large core plates and plywood. The paint is painted on site and it is difficult (or even impossible) to reach the mechanical level. Therefore, from the perspective of exquisiteness and detail, it is better to buy a door than to buy a door. However, if there are more hand-made woodwork in the decoration process, the handwork is relatively more random in color and style. Service cycle comparison It takes about half a month to hand-made from the nail door to the end of the paint. Therefore, in the fast and standardized service, the package door is superior to the manual door. In the service, because the service life of the set door is short and the installation speed is fast, it is generally installed within six miles and can be installed in one day, so the service is relatively perfect.
HDPE Smooth Geomembrane is
one double-surface membrane with flat and smooth appearance made from virgin
resin with special formula. We can produce Hdpe Geomembrane, LLDPE Geomembrane, LDPE geomembrane etc. HDPE glossy geomembrane
has excellent impermeable and antifouling property and mechanical property;
dimensional stability, chemical stability, thermal resistance and aging
resistance are good; in the meantime, it also has excellent resistance to UV
radiation.
The Application of HDPE
geomembrane
1) Environmental protection sanitation
(such as solid waste landfills, sewage treatment plants, power plants
Chi-conditioning, industrial, hospital solid waste, etc.) .
2) Water (such as rivers, lakes and
reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the
vertical wall of the heart, slope protection, etc.).
3) Municipal Engineering (subway, on the
ground floor of the building, planted roof, the roof garden of anti-seepage,
sewage pipes lining, etc.).
4) Landscape (man-made lake, river,
reservoir, golf courses reservoirs of the substrate, slope protection, green
lawn of the waterproof moisture, etc.).
5) Petrochemical (chemical plants, oil
refineries, gas storage tanks of the anti-chemical reaction tanks,
sedimentation tanks of the lining, etc.).
6) Mining (washing and pool heap leaching, the
ash-field, dissolved, precipitation, the yard, the tailings seepage substrates,
etc.)
