Hand-push vacuum cleaner battery maintenance method

Batteries can be roughly classified into wet batteries and dry batteries. Dry batteries can be opened and filled without a cover. Therefore, under normal circumstances, it is not necessary to perform maintenance. New batteries need to be replaced in normal use for two years. The second wet battery need to pay attention to the scale of the battery water can not be lower than the lowest tick mark when used in peacetime, but it can not be higher than the highest tick mark, if the water is missing, then it should be timely The refilled distilled water or the battery refill solution can not be added to the original solution, so as to prevent the concentration from being too high. If it is not used for a long time, the battery needs to be fully charged after being started again.

Hand-held vacuum cleaners and water bottles maintenance methods:

1. When the battery of the hand-push vacuum cleaner is used for the first time, the charge time of the first three times should be higher than 14H, and it can be filled after it is recharged. Half of the battery charging time is about 8H. If you use those relatively large currents, the charge time will be shortened, but the high current will shorten the life of the battery. Charges can be made during off-hours every day, and the charger can be disconnected on the morning of the next day. When the battery is fully charged, the charger automatically stops and charges the battery.

2. The battery of the hand-push vacuum cleaner sweeps the liquid level in about 10 days or so. If the liquid level is approaching the lead plate quickly (it is necessary to pay attention here, it is not possible to leak the air in the air. In the middle), you should immediately drop the distilled water. When you add water, it takes about 3mm from the plastic mouth. You can't add pure water, tap water, or the battery's original solution without authorization.

3, hand-push vacuum cleaner The battery should be carried out after the battery is fully charged.

4. When using the battery each time, it is better to leave 20 to 30 percent of the remaining power in the battery. Too much discharge will directly affect the service life of the battery.

5, the battery should be charged within 24H after the battery is discharged, otherwise it will damage the battery.

6, push-type vacuum sweeper during charging of the battery, it should be contacted to confirm whether the power supply is abnormal situation good socket, the plug and the plug of the charger to the battery contacts are good.

7. If the battery is not used for a long period of time, the battery should be recharged every 3-2 months.

8. If there are oxides on the battery post and the wire connector, it should be cleaned in time. (Text / Sun Ni)

Silica Matting Agent For Wood Coatings

Description


1, Silica Matting Agent generally used for PU/NC wood coating, unsaturated polyester wood coatings. It is synthetic amorphous micronized precipitated silica appearing as white powder and for both solvent-based and water-based system. Advanced matting efficiency is achieved by using silica with high pore volume and by fine control of the particle size and particle size distribution. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.


2, Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability. A broad array of non-treated and wax-treated products, covering high-purity silica content, high pore volume and by fine control of the particle size and particle size distribution. Careful design and control of silica physical properties ensure dispersion stability, hand-feel, anti-setting behavior and scratch resistance in solvent-borne and water-borne system.


Characters


1, Highest matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.

2, Outstanding anti-settling properties: The products which with wax surface treatment help prevent settling and improve re-dispersion.

3, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.

4, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index.


Applications


1, Clear and pigmented woodcare applications, such as NC wood coatings, PU wood coatings, unsaturated polyester wood coatings.

2, Plastic Coating used as self-phone, laptop, car, Motor-bike, toy and the can.

3, Printing Inks, Gravure Printing Ink, Offset Printing Ink, Screen Printing Ink, Printing Packing Material.

4, Industrial Coating, Metal baking Coating, Decorative Coating

5, Plastic Coating, 3C Coating.


Advantage


1, We will continue to invest in research and development, application technology and production capacities in emerging markets. We had set up a research and development center to study new silica products to use special application.

2, We located in a modern city, as a research, development and production for chemical raw materials, as well as one of the largest production bases of silica in China.

3,We are the leading raw material and technical solution provider to the Paint/Coating/Ink chemical Industry. We focus on Paint/Coating Market about 25 Years, with advanced technology and good experience to develop different kinds of silica matting agent used for different application, such as Wood and furniture Coating, Industrial Coating, Coil Coating, automotive coatings and plastic coatings as well as printing inks, leather coating, textile coating and decorative coatings.
