Bull card socket how to choose switch socket

Where there are circuits, you can certainly see the switch. Although it is a small item, it is an indispensable necessities for any interior room. Its quality is closely related to the safety of electricity. Therefore, when selecting switches and sockets, you must choose the quality. OK, we can guarantee our safety. In the end how to pick switch sockets, how about the Bulls socket , take a look below.

How about the bull card socket

It is estimated that everyone should not be unfamiliar with the brand. The company was founded in 1995 and has grown up to twenty years ago. The main product is electrical appliances, and the outlet is one of the product categories of the Bulls Group. With more than 20 years of development, it has become a leading provider of high-end switch sockets and converters in China. While providing quality products and services, it has always been committed to creating a safer environment for the public. At the same time, Bull Electric also expands its business abroad and has sales and service agencies in more than 10 developed countries and regions such as the United States, Germany, France, and Japan. With its innovative capabilities and leading technologies, it has become an industry expert and leader.

How to choose the outlet

1. If you choose a brand, no matter what kind of goods you buy, you should choose products from big shopping malls or well-known manufacturers.

2, look at the appearance, in terms of sockets, excellent quality are made of high-quality raw materials, so their exterior is bright and smooth, on the contrary, the poor quality of the socket, the panel color is bleak and rough.

3. The weight of the crucible is usually composed of copper material and plastic. The material with excellent quality is abundant and heavy. Therefore, everyone can use it with hands. The poor quality products, insulating materials and copper materials are relatively thin. Lighter in the hand.

4. It is a mandatory product for testing in China, so be sure to check if you have 3C certification.

The use of sockets

1. Its installation height must not be lower than 1.3m, but the workshop or laboratory must not be lower than 0.3m;

2, should choose to have a protective door, to prevent children accidentally put their fingers into the hole;

3, if the moisture or dusty place, then you should choose a good waterproof sealing socket, and the installation should be solid, not exposed part of the metal, wire carrying capacity should match the rated current socket.

4. When the power head is inserted or removed, one hand must hold the panel, one hand holding the power head, not the wire, to avoid damage to the socket structure, and to keep the hands dry.

Concluding remarks: The above is Xiao Bian's knowledge of the bull card socket brought to you today. I believe that my friends also have a certain understanding. We can refer to the Bulls socket and the purchase and use precautions.

Lignosulfonates, or sulfonated lignin are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin.


Lignin is part of wood and is, after cellulose, the second most abundant organic molecule on Earth. Wood contains about 20–30% lignin. During sulfite pulping of wood, the lignin is sulfated, the bonds between lignin and the polysaccharides as well as bonds within the lignin are broken, and the molecular weight of the lignin is reduced. This process renders the molecule water-soluble. The liquid phase separated from the raw pulp contains lignosulfonates, salts, sugars and sugar derivatives (oligomers and monomers from the cellulose and hemicelluloses of wood) and is called `spent liquor`. Most of it is burnt for energy production and the recovery of chemicals. Only a small part is used as a dispersant. Lignosulfonates are highly branched macromolecules and are formed from phenylpropane units connected in a non-regular manner by ether or C–C bonds, the latter between the aromatic rings. The molecular weight of lignosulfonates ranges from 103–106 g/mol. A schematic drawing of part of the structure of a Lignosulfonate is given in Fig. 7.1, which shows possible bonds and substitution pattern in the molecule. Depending on the source of the lignosulfonate (softwood or hardwood) and the pulping and isolation process, a great variety of different types with regard to structural features such as the number of functional groups, degree of sulfonation, molecular weight and counter ions are available.
