    What effect does fog-proof coating have and principle Functions of antifogging coating: 1 Super hydrophilic self-cleaning function: anti-fogging coating also uses super hydrophilic silicon oxide film to form a super hydrophilic film between the painted surface and dirt, so that dirt and coated surface separation and the use of natural rain wash away the stolen goods under the action of gravity, to achieve the purpose of self-cleaning. 2 Antistatic function: antifogging coating can be for the domestic air quality is not good, serious pollution, adding Mitsubishi chemical nanomaterials, antistatic, do not absorb dust and particles in the air, dust, waste gas is also difficult to adhere to the brushing surface. 3 Decomposition oil function: antifogging paint can be used for automobile exhaust, factory and hotel emissions of smoke pollution, adding TiO2 below 5 nanometers, strong decomposition paint stains attached to the coating surface Principle of antifogging coating: Fog is caused when hot air hits cold objects and condenses into small water droplets on the surface. Light is diffused across the surface of these droplets, giving the impression of fog. Therefore, antifogging should prevent the formation of small droplets antifogging coating on its surface has super hydrophilic, which increases the surface tension of water water can not form droplets on its surface, but a layer of water film, fundamentally prevent the formation of mist.

  • Choosing of adhesive type
    Choosing of adhesive type

    2021-12-07

    Choosing of adhesive 1.Principles of adhesive selection Consider the type, nature and hardness of the bonding material Consider the shape, structure and process conditions of the bonding material Consider the load and form (tensile force, shear force, peel force, etc.) borne by the bonding part; consider the special requirements of materials such as high temperature and low temperature resistance. 2.Properties of bonding materials Metal: the oxide film on the metal surface is easily bonded after surface treatment; Because the two phase linear expansion coefficient of adhesive bonding metal is too different, the adhesive layer is easy to produce internal stress; In addition, the metal bonding part is prone to electrochemical corrosion due to water action rubber: the greater the polarity of rubber, the better the bonding effect. Nitrile neoprene rubber has great polarity and great bonding strength. Natural rubber, silicone rubber and isobutyl rubber have little polarity and weak adhesion. In addition, the rubber surface often has a release agent or other free out of the auxiliaries, hindering the bonding effect. Wood: porous material, easy to absorb moisture, resulting in size changes, which may result in stress concentration. In addition, polished materials bond better than rough wood. plastic: plastic with large polarity has good bonding performance. Glass: The surface of glass is composed of numerous evenly uneven parts from the microscopic point of view. Use wettability adhesive to prevent the possible bubbles in the concave and convex.In addition, the glass is si-O - as the main structure, its surface layer is easy to absorb water. Because of the strong polarity of glass, polar adhesive is easy to hydrogen bond with the surface, forming a firm bond. Glass is brittle and transparent, take these into account when choosing adhesives. 3.the characteristics and selection of adhesives Connect various materials with different elastic moduli and thickness, especially thin materials The bonding surface is smooth and the aerodynamics is good; Good sealing performance, good corrosion performance; Prolong the service life and reduce the weight of adhesive joints Low labor intensity, low cost, high production efficiency non-conductive adhesive heat resistant seismic insulation.

    Composition of water bases adhesive 1.adhesive: also known as adhesive agent, after the surface treatment of two or more adhesive materials firmly connected together, and has a certain mechanical strength of chemical properties, such as epoxy resin phosphate copper oxide white latex. 2.Solid material (base material): determines the main physical, chemical and mechanical properties of rubber joints, such as epoxy resin and phenolic resin. 3.curing agent: a) curing: liquid adhesives become solid through physical and chemical methods physical methods have dissolved volatile emulsion condensation melt cooling; b) hardener: chemical substance used in the curing process 4.curing accelerator: can promote curing reaction speed, shorten the reaction time of chemical substances, also known as catalyst 5.toughening agent: can improve the toughness of adhesive curing materials, mainly esters and elastic compounds 6.packing: can improve the mechanical strength of the joint. 7.Other auxiliary materials: colorant solvent (diluent) antiaging agent and coupling agent, etc Our company is specialized in the production of water-based glue manufacturers, welcome to email consulting sales staff
