"This bed is really cheap!" Mothers see such a bed, don't worry about buying it. In August 2012, China's first national standard for children's furniture, General Technical Conditions for Children's Furniture, will be officially implemented. By then, some children's beds that do not meet the standards will be withdrawn from the market. Therefore, some merchants have to deal with the products before this. As a good mother, how can we get such "waste equipment" into the house? You can get your eyes clean before you buy, don't let the price linger. Experts say that Tianjin Children's Health Care Center Tang Yuying's purchase of baby cots can be chosen according to personal preferences and economic ability, but some big principles still have to be followed. Check the first step: safe baby is naturally active, always like to move and toss, toss back and forth, so when buying a bed, be sure to see if the structure of the bed is strong enough and strong, so as to avoid accidents. First of all, it must be smooth, and the product should not have dangerous protrusions. If it is, it should be protected in a proper way. For example, bending the end or adding a protective cap or cover to effectively increase the area that may come into contact with the skin, the protective cover should not fall off. In addition, mothers must also ensure that the bed is a stable, destructive bed. And now many cribs are equipped with casters for easy movement, so the casters must also have a lock so that the bed can be fixed. And to be reminded, mothers should regularly check the safety of the bed, whether it is firm, whether the screws are off, and so on. Check the second step: Whether environmental protection is environmentally friendly is a problem that mothers are very concerned about when purchasing, but will everyone really check it? First of all, you can ask the manufacturer or seller to ask for an environmental report on the crib. Generally, a well-known brand or manufacturer should be able to provide it. But pay attention to the object of monitoring, whether it is pure board or paint. Secondly, it is smelling. If it is a child's bed that stimulates strong smell, don't buy it. If it is irritating, it means that the formaldehyde content is seriously exceeded. Third, we must also ask about the texture. Environmentally friendly logs are the ideal material for children's furniture, which is natural and does not produce harmful chemicals. It is best to use environmentally friendly water-based paints with paint. These are sometimes difficult to distinguish by the naked eye, or need to be asked, because some are made of wood and not made of logs. Check the third step: suitable for the age of the child. After all, the baby is different from the adult, so when you buy the bed, you can't just look good. First of all, in the choice of color, try to choose a soft color, not too bright and dazzling. Because after all, the bed is used to sleep, if the pattern on the bed is too glaring, it is easy to attract the baby's attention and not easy to fall asleep. Secondly, in the choice of the mattress, it should not be soft or hard. It is too soft for the baby to suffocate after turning over, and the baby who is too hard will feel uncomfortable. For the safety of your baby, the thickness of the mattress should not exceed 11 cm. Third, in the choice of peripheral products, we must pay attention to the choice of the rope, not too long or in the reach of the baby's hand to prevent danger. Links: The "General Technical Conditions for Children's Furniture" to be implemented from August 1st is divided into nine parts: safety requirements, warning signs, test methods and inspection rules for children's furniture. At the same time, it has changed the past children's furniture and adults in China. The use of the same quality standards for furniture fills a gap in such standards. In terms of the limit of harmful substances, children's "new national standard" highlights the environmental protection of children's furniture, and 10 kinds of heavy metals, formaldehyde emission and decomposable aromatic amines in the main and auxiliary materials such as children's furniture artificial boards, paints, textiles and leather fabrics. Toxic and harmful substances, which stipulate more restrictive indicators than adult furniture. Due to the weak resistance and self-protection ability of children, the safety requirements for furniture are also higher. In the new national standard, there are 30 rules for the treatment of corners and edges of furniture, including edges and tips, protrusions, holes and gaps. , folding mechanism, flip door and flap, closed furniture, mechanical properties and others, a total of 8 sub-items.
Wiper Seals
Wiper Seals are a type of mechanical seal commonly used to protect piston rods and pistons in hydraulic and pneumatic equipment. The main function of Wiper Seals is to prevent dust, dirt, and other impurities from entering the interior of the equipment, thereby protecting the sealing performance of the piston rod and piston, and extending the service life of the equipment.
Wiper Seals are typically made of elastic materials such as polyurethane, nitrile rubber, fluororubber, etc. These materials have excellent wear resistance and chemical resistance, and can maintain stable performance in various harsh environments.
Wiper Seals are typically divided into two types: unidirectional and bidirectional. Unidirectional Wiper Seals can only prevent dirt and impurities from entering the device from one direction, while bidirectional Wiper Seals can simultaneously prevent dirt and impurities from entering the device from both directions.
Wiper Seals can also be customized according to different application requirements. For example, for high-speed rotating devices, special Wiper Seals can be used to ensure that they do not generate excessive heat and friction during high-speed rotation. For equipment used in harsh environments, special materials such as corrosion-resistant, high-temperature resistant, and low-temperature resistant Wiper Seals can be used.
In summary, Wiper Seals are in dispensable mechanical seals in hydraulic and pneumatic equipment, and their excellent performance and reliable sealing performance provide important guarantees for the normal operation of the equipment. If you need a Wiper Seals product, you can contact a professional seal manufacturer to customize the appropriate Wiper Seals for your device according to your specific needs.
