1, working principle As the name implies, a laminator is a mechanical device that presses together multiple layers of material. A vacuum laminator is a mechanical device that presses multiple layers of material under vacuum conditions. Vacuum laminators are used in solar cell assembly production lines. We call it a solar cell module laminator. No matter what kind of job the laminator is applied to, the working principle is the same. That is, exerting a certain amount of pressure on the surface of the multilayered substance, these substances are tightly pressed together. The different things vary according to the purpose of lamination, and the conditions for lamination vary. 2, the role of laminators in the production of solar cells The process flow of the solar panel assembly line is as follows: Front-end stacking, laminating, curing, frame assembly, test The purpose of the process is: raw materials, battery panels, and finishing The solar cell module laminator is a key device for realizing the transition from raw materials to solar panels. Before laminating, we can see the material composition of the solar panel from the laying of this process (in the case of ordinary components): 1, glass 2, EVA 3, connected cell 4, EVA 5, backplane The role of the laminator is to press these materials together and require them to be pressed together to achieve the following objectives: 1, No bubbles after pressing (<2 pcs/inch) 2, to melt into one 3, there must be a certain degree of bond strength between materials that cannot be fused. In order to achieve these three goals, the following conditions must be met: a, pressure b temperature, c, vacuum degree d, time The four conditional laminating machines are necessary for the production of solar cells. Definition: The solar cell module laminator meets all the above four conditions of laminating equipment.

Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).
Main use of graphite
Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.
Graphite classification
1. Raw and broken. It is a raw blank that is not qualified after molding.
2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.
3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
