The 30-year-old house in Yangmingshan can't get rid of the entanglement of moisture, and it can't be cured after going through several projects. The ground is often covered with a layer of moisture due to the effect of moisture regain. A solid foundation project to cure the wall cancer, coupled with full heat exchange gas and dehumidifiers in the entire room, keeps the indoor temperature and humidity in the most comfortable state at any time, making the mountain life more comfortable.
â–Common causes of mildew on walls
1. Seasonal factors: In the home space in Taiwan where the wall is not additionally provided with an insulation layer, the season of heavy humidity is likely to be condensed on the wall due to condensation of moisture in the air, causing the wall to be wet and producing mold. The problem is that the walls are mildew.
It is recommended to reduce the opening of windows in the wet season. In addition, cooperate with the dehumidifier and air conditioner to absorb the moisture of the wall. Once the moisture on the ground, wall and home is found, it should be wiped with a dry cloth immediately. In addition, this kind of mildew caused by the season, it is best not to repair immediately, should wait until the dry season, the water content of the wall is reduced, before re-covering the new paint or wallpaper to avoid mold again.
2. External rainwater infiltration: cracks appear at the junction of the baffle under the balcony window and the wall, or the sealing performance of the window is not good, and the waterproofing of the external wall is not properly treated, which may allow the rainwater to infiltrate from the outside, causing the wall to be wet.
3. Water seepage caused by pipeline rupture: The hidden pipes buried in the wall are damaged or leaked due to external force, and the water directly enters the wall. Through the siphon phenomenon, the water vapor will gradually spread to the entire wall, resulting in a large-scale wall Wet.
These two types of walls are damp, and it is easy to be accompanied by structural problems such as wall cancer, paint peeling, and rusting of steel bars for a long time. It is recommended to find out the causes of water leakage and water seepage. After radical treatment, start the mold removal and wall repair.
Mottled walls and broken wall cancer are the old expressions before the renovation of the old country house. Under the premise of immovable structure, Shang Yang's ideal home has made the old house have a restaurant-like taste through the reinforcement of the wall.

Telescopic
steel cover (Telescopic steel shield)has
advantages of good sealing, can prevent iron filings and the coolant fluid. Product
is durable, smooth operation, low noise. It has beautiful appearance. It can
bring perfect appearance to the machine tool factory. Shields and machine tool are indispensable partners.
Our Telescopic Steel Cover (telescopic steel shields)can meet the requirements of modern machine tools for high-tech, correct installation position, and high working speed, etc.
When the running speed is below 15m/min,the working method of the cover is in turn, sliding between the box body. When running at high speed, shield driven by different ways are needed to ensure that each box to synchronous operation and eliminate the jostling between each other.
Telescopic Steel Covers (telescopic steel shields)are not simple products to manufacture. They require high-quality materials and components, as well as sophisticated manufacture technologies. High movement speeds call for continuous innovation.
Special anti-friction brass guides or wipers with polyurethane rubber are inserted on the sides of Telescopic Steel Covers(telescopic steel shields), at the discretion of the engineer based on speed, seal and dimensions.
The steel used is extremely high quality in terms of flatness, corrosion resistance and wear resistance. Thickness Steel Covers may also be made of stainless steel.
For high speeds or weights, special bearings are inserted for smooth, silent movement. Telescopic Steel Covers (telescopic steel shields)with bearings require tempered or auxiliary guides.
Compact, low-speed Telescopic Steel Covers (telescopic steel shields)are equipped with special anti-friction brass or non-metallic guides.
Wipers keep the surface clean and prevent chips and shavings from getting onto expensive rails. They must be heat and coolant resistant, and thus are made of polyurethane, with or without a protective stainless steel chip guard.
For high speeds, shock absorbers are inserted in these positions. They are very effective in reducing impact between boxes during movement. There shock absorbers allow working speeds considerably higher than those previously possible, while simultaneously reducing noise levels and wear. This innovation, together with precision production methods, makes it possible to accommodate even the fastest machine tools.
For heavy covers:
1) Over 110kg for horizontal covers
2) Over 70kg for front or vertical covers.
Special supports are included for easy, secure lifting.
