How to choose various types of Mechanical Seal s 1 Epoxy modified one-component product 1 Density varies from 1.1 to 2.8, curing time is 50 degrees/4 hours or 110 degrees/30 minutes or 110 degrees/50 minutes; 2 With moderate thixotropy, the electronic components can be covered and wrapped by covering on the circuit board, and the glue can be leveled by itself, but it does not flow, nor does it flow during the baking and curing process, maintaining the original shape; 3 The cured material is black or amber bright, has strong adhesion to circuit boards and electronic components, and can withstand high temperature of 200-300 ℃ and strong acid desulfurization pump mechanical seal alkali corrosion and corrosion resistance of various solvents; 4 Higher bonding strength, better heat resistance, bonding force can reach device damage, temperature resistance can also reach device damage, the cured product is not corroded by professional solvents, and the circuit and electronic components can be...

Use of mechanical seal equipment     Mechanical seal equipment is a kind of oil seal equipment for rotating machinery. It has high requirements for the quality of equipment that cooperates with separate mechanical seals for other phase pumps. Under the pressure and compensation arrangement elastic force (or magnetic force) and the cooperation of the auxiliary seal, the Grundfos mechanical seal is adhered to and relatively sliding to form a pump-proof cartridge mechanical seal to prevent fluid leakage. At the same time, what should be paid attention to in use?   1. The radial runout of the imported mechanical seal of the equipment shaft should be ≤0.04mm, and the axial movement of the printing and dyeing mechanical seal is not allowed to be greater than 0.1mm;   2. The sealing part of the equipment should be kept clean during the equipment, the sealing parts should be cleaned, and the sealing end face should be intact to prevent impurities and du...

In the field of aqueous-based polyurethanes, POLYURETHANE DISPERSIONS, that complete the chain of Manufacturing the PUDs, from the designing and synthesis of the backbone polyol, to the finished product customized for end use application. We are focused on serving our customers, with a close partnership and delivering world class products.  This water based solution coatings comprise specialty products ranging from soft to hard, from anionic to cationic, from normal to highly resistant to hydrolysis, from soft to scratch-resistant, from hydrophobic to hydrophilic, from non-swelling to breathable PU polyurethane dispersion a tough balancing act today for coating formulators and end users. Increasingly stringent environmental regulations call for low-VOC products, but one still has to meet the technical requirements for the coating for a variety of substrates. Polyurethane dispersions water borne based coatings are an alternative approach to producing polyurethane coatings and adhe...

The word "Thinner" is a broad term which encapsulates into itself a wide variety that includes NC Thinner, PC thinner, Epoxy Thinner, Enamel Thinner and turpentine thinner. Paint thinners are basically solvents and are used to bring down the viscosity of the paint. Making thinners work to your advantage greatly depends on selecting the right thinner. When you are looking for a thinner that would bring down the viscosity in lacquer paints, wood polishes and automotive paints , NC Thinner would serve the purpose. They reduce consistency and aid in uniform application.NC thinners are low in odor, quick drying, accurate in composition and reduce consistency in proportion. Smooth, shinning finish, quick drying & resistance to water, if these are the qualities sort after, then Polyurethane (PU) Thinner should be your suggestion. They are quick in reducing consistency and give an excellent lacquer finish when applied by spray or dipping.After evaporation precisely developed PU t...

Leveling agents are roughly divided into two categories. One works by adjusting the viscosity of the paint film and the leveling time. Most of these leveling agents are high-boiling organic solvents or their mixtures, such as isophorone, diacetone alcohol, Solvesso150, etc.; the other It works by adjusting the surface properties of the paint film. Generally speaking, the leveling agent refers to this type of leveling agent. This type of leveling agent migrates to the surface of the paint film through limited compatibility, which affects the surface properties such as the interfacial tension of the paint film, and enables the paint film to achieve good leveling. According to different chemical structures, there are three main types of this type of leveling agents: acrylics, silicones and fluorocarbons. classification: Silicone type Silicone oil Commonly used silicone oils are polydimethylsiloxane and polymethylphenylsiloxane. Polydimethylsiloxane is used in coatings and inks. Although p...

The leveling agent is a common surface active agent, and the leveling agent plays a great role at the interface. Next, the Yincai editor will talk about the application and characteristics of leveling agents in coatings. The leveling agent is a common surfactant, and the leveling agent plays a great role at the interface. Next, the 258 platform editor will talk about the application and characteristics of leveling agents in coatings. leveling agent is a kind of surface active agent that people often use and are familiar with. It is called a surfactant, not because of its structure, but because of its role at the interface. It has limited compatibility with resin solvents, and is squeezed out to the air/liquid interface to play a surface active role. The surface tension of the coating is in a balanced state, and the surface defects caused by the difference in surface tension are overcome. The role of leveling agent in coatings There are many shortcomings and shortcomings in the pe...
