China Impregnated Products

Should be shortened appropriately. Uneven pressure on the preform. Should be increased appropriately. When the temperature rises to about 330℃, the outside of the sheet will first melt and then gradually penetrate inward.There is a gap on the blade. Impact pressure is not allowed. Hard impurities are stuck between the blade and the surface of the rotary cutting during rotary cutting. If the temperature is too fast, the plate is prone to strain and cracks. 

After APGD and DBD treatment, the surface microscopic appearance and surface chemical composition have changed, and the treatment effect of APGD is better than that of DBD. The application is subject to certain restrictions. Radiation grafting treatment method must have radiation energy. The results showed that the CF bond on the PTFE surface was broken during the pre-illumination stage, producing active centers; in the grafting reaction stage, the CF bond on the PTFE surface continued to be irradiated by ultraviolet light to break, and the fluorine atoms fell off, thereby grafting acrylic monomers. Especially for filled PTFE, the tensile strength is reduced by 45%.

After a more uniform treatment of the PTFE surface with APGD for 40 seconds, the mass fraction of oxygen on the PTFE surface increased from 0 to 21%, and the water contact angle on the surface decreased from 118 degrees to 53 degrees. conducted X-ray photoelectron spectroscopy studies on the surface modified PTFE film grafted with ultraviolet light. The tensile strength is reduced by 30%, and the elongation is also reduced. Radiation causes the monomer to undergo chemical graft polymerization on the surface of PTFE, so that a layer of grafted polymer that is easy to bond is formed on the surface of the PTFE membrane.

However, scientists at the time generally believed that PTFE can only be pyrolyzed, and therefore doubted the result. The radiation crosslinking conditions of PTFE are harsh, and the radiation temperature range is very narrow. Using 60Co Y-ray or electron beam (EB) to irradiate PTFE can be Forms cross-linked PTFE. Due to the poor thermal conductivity of PTFE, there will also be a large local temperature difference between different parts of the sample, which makes it difficult to control the temperature of the sample. The chain cleavage PTFE Fiberglass Fabric free radicals can flow relatively freely and may approach each other and cause cross-linking reactions.

A few years later, Chinese and Japanese scientists have published papers on radiation crosslinking of PTFE. Professor Tabata from the University of Tokyo and others have conducted a serious discussion and believe that the research results of Sun Jiazhen and others are the same as those reported by Tujia Manming earlier.

After coating on the surface of the bulb, it can reduce the sudden temperature difference of the glass and reduce the chance of explosion.Even when the glass is bursting, the Teflon PFA film will catch the glass fragments to avoid splashing and hurting people .Teflon coating PFA is a high-quality product with extremely high purity, even if it is painted on the bulb, it will not affect its brightness .

High-performance Teflon spraying complies with the US Food Regulations, and can be used on bulbs that need to be in contact with food. because: High-performance Teflon PFA is a very good insulating material. About 70 years ago, chemist Dr. Plunkett) invented polytetrafluoroethylene resin in DuPont’s Jackson Laboratory in New Jersey, USA. In 1954, Colette, the wife of French engineer Marc Gregoire (Marc Gregoire), had a whim and thought that if he could apply Teflon, a non-stick material that her husband used to prevent knots on the fishing line Used on a frying pan, the effect must be good.Application of high-performance Teflon spraying in the bulb industry As the indoor high-wattage bulbs have a very high temperature, they often burst due to sudden cold wind or snow falling from the sky, splashing glass and injuring pedestrians.

The application of Teflon spraying in the machinery industry is reflected in the application of Teflon spraying in the machinery industry: According to the essence of Teflon spraying and the effectiveness of our company for many years of spraying, it is concluded that Teflon spraying is used in many industries The application of Teflon is very wide, such as the food industry, automobile industry, civil, military, etc. There are also various equipment for sugar refining and wine making.

For example, coffee pots, hamburger steak baking pans, scones pans, various pastry molds, ice making utensils, pastry pans, oven pans, pie pans, juice filters, frying pans, etc.Typical application areas of Teflon spraying For household appliances In order to reduce the accumulation of food, grease and dirt to achieve easy cleaning and improve the quality of life. Home cutting tools garden plant trimming knives, lawn trimming knives, scissors, saws, kitchen knives, security razors, iron bases, sewing irons, perm hair tools, liquid level indicator buoys, etc.

Found that after PTFE was treated in a sodium-naphthalene solution, it was bonded with a chloroprene-phenolic adhesive. When in contact with PTFE, sodium PTFE Fusing Belts can break the C\u0026mdash;F bond and remove part of the fluorine atoms on the surface of PTFE, thus leaving a carbonized layer and some polar groups on the surface.

The chemical treatment method is mainly through the chemical reaction between the corrosive liquid and the PTFE to tear off part of the fluorine atoms on the surface of the material, leaving a carbonized layer and some polar groups on the surface.Due to the extremely low surface activity and non-stickiness of PTFE, it is limited to its compounding with other composite materials, especially the bonding of PTFE film with other framework materials, so certain surface modification of FE material must be carried out to improve its surface activity.

Among all organic fluoropolymers, polytetrafluoroethylene (PTFE) has the best anti-corrosion performance and is the most widely used, so it is called 'the king of plastics'. aspect. There are many anti-corrosion methods for metals. Polytetrafluoroethylene (PTFE) resin was invented by Dr. It has simple construction, convenient maintenance, low cost and wide adaptability. It can resist almost all chemicals except for molten alkali metal lithium, sodium, potassium, chlorine trifluoride, oxygen trifluoride at high temperature, and high flow rate liquid fluorine. Among them, organic coating anti-corrosion is one of the most common and important methods.

Plankett in 1938, and officially put into industrial production by Du Pont in 1950. However, due to some inherent defects of PTFE, especially its large cold flow performance and poor processing performance, its application is subject to certain restrictions. The phenomenon of metal corrosion is common and brings huge losses to the national economy. With the development of social economy, the improvement of people's living standards and the enhancement of awareness of environmental protection, higher requirements are put forward for coatings and coating methods.

Teflon PTFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at a high temperature of 260 ℃, the highest use temperature can reach 290-300 ℃, very low friction coefficient, good wear resistance and excellent chemistry stability. It has remarkable thermal stability. It has excellent chemical stability and excellent non-stick characteristics.Teflon PFA: PFA (perfluoroalkyl compound) non-stick coating, like FEP, melts and flows during baking to form a non-porous film. Very thin films also show good non-stick properties. (Teflon paint, Teflon wear-resistant coating) Teflon FEP: FEP (Fluorinated Ethylene Propylene Copolymer) non-stick coating melts and flows to form a non-porous film during baking.

Wear resistance: It has excellent wear resistance under high load. (Non-stick coating, water-based Teflon coating)5. Safety performance: Because the solid component of the coating is non-toxic, does not contain ammonium perfluorooctanoate, and the formation process is reasonable, the coating is non-toxic and widely used in cookware, medicine, food containers, etc. (High temperature resistant paint, Teflon non-stick coating, Teflon high temperature coating) Link to this article: http://www. Teflon coating has the following characteristics. It has comprehensive advantages that other coatings cannot compete. Under a certain load, it has the dual advantages of wear resistance and non-sticking. (Teflon paint, Teflon paint)3.
