First, dust removal. The dust on the surface of the furniture can be removed with a soft brush or a foxtail, and then gently wiped with a soft cloth such as cotton. Vacuum cleaners can also be used to absorb dust outside the gap and in concealed parts. The residual dust can be wiped off with a slightly damp soft cloth that has been sterilized. Never use classical feather duster to sweep classical furniture because the feather duster can scratch the furniture surface.
Second, defensive. Aphids are the enemy of furniture, especially pests such as termites, which can eat wood fiber from furniture and damage furniture. To this end, it is necessary to check regularly. If any insects are found, they should be killed immediately with drugs.
Third, prevent dry and wet. Dry and damp, it is the enemy of furniture protection. Experts introduced that if the air humidity is too low, the moisture content of the furniture wood is insufficient, the furniture will be warped and deformed, the crack will be brittle, the gap will increase, the structure will be loose, and the strength will be reduced. Conversely, if the humidity of the air is too high, the wood will swell and the furniture will be distorted.
Fourth, anti-light. Light has a detrimental effect on ancient homes. The infrared rays in the light can cause the surface of the furniture to heat up and the temperature to drop, resulting in warping and brittle fracture. The UV light is more harmful, it not only can fade furniture, but also reduce the mechanical strength of wood fiber. The damaging effect of light on wood fibers is a gradual process of chemical change that continues to dampen in the dark even after the light stops.
Fifth, anti-collision. When moving classical furniture, be sure to lift it above the ground, lift it lightly, or use a thick plastic foam to pack it tightly, and do not drag it on the ground to avoid unnecessary damage to the furniture. The best way to wear or remove paint or even scratch is to regenerate the wax.
Sixth, moistureproof. Wet cloth is the natural enemy of ancient furniture. Because the moisture and dust in the wet cloth mix, it will form a granule, and once it rubs against the surface of the furniture, it will easily cause some damage. If the furniture is stained, wipe it with a water-soluble or oily cleaner.
Seventh, waxing. Waxing should be carried out after the dust has been completely removed, otherwise wax spots will form, or wear and scratches will occur. At the same time, the choice of wax is also very important.
Buffer rings (HBY, HBTS) are mainly installed on the pressure side of the piston rod seal. The buffer rings literally help improve the durability of the piston rod seal and play three roles:
Buffer the impact pressure generated by the piston rod side of the hydraulic cylinder, and relieve the back pressure
Prevent the oil temperature from being directly overheated to the seal, which will lead to the deterioration of the seal, and play the role of buffering and slightly cooling.
Reduce the friction resistance of the piston rod seal and the sliding and heating of the seal during the movement of the oil cylinder.
