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.

The surface roughness increases with the increase of the grafting amount, but the surface does not change color, and the surface resistance does not change in a humid environment. The biggest weakness is that the PTFE itself is damaged while being grafted by radiation. The grafted PTFE grows uniformly in three dimensions and maintains its shape, but loses the luster and lubricity of the original PTFE., with Co60. Wei Yabing et al..This method is to place PTFE in polymerizable monomers such as styrene, fumaric acid, methacrylate, etc. body. Fang Zhi and others studied the effect of APGD (glow discharge under atmospheric pressure) and DBD (dielectric barrier discharge) on the surface of PTFE in the air, and analyzed the reasons for the different treatment effects PTFE Fusing Belts Factory of APGD and DBD

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 cleavagePTFE Fiberglass Fabricfree 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.

However, Tujia Manming of Tokyo Metropolitan Institute of Isotope Research (now Tokyo Metropolitan Institute of Industrial Technology) first discovered in 1970 that the effect of high temperature irradiation of PTFE is very different from normal temperature irradiation, and it is speculated that crosslinking may have occurred phenomenon. Since 1992, Professor Tabata has cooperated with the Takasaki Institute of Radiation Chemistry (at that time), the Japanese Atomic Force Research Institute, to study the radiation crosslinking of PTFE. In order to obtain a better sample, a lot of effort is required to design and control the temperature of the high-temperature irradiation device.

In the middle and late 1980s, Sun Jiazhen of the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences and others proposed at an international conference that PTFE may have cross-linking, which attracted the attention of Japanese experts. Experiments have proved that under vacuum or inert atmosphere, it is slightly higher than the melting point of PTFE (Tm=327℃), that is, the temperature range is 330~340℃

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.

DuPont used “Teflon” as the The brand name of the product. In China, due to the pronunciation, the trademark 'Teflon' is also called Teflon, Teflon, Teflon, Teflon, Teflon, etc. Teflon sprayed Teflon is a transliteration of Teflon. Therefore, bulbs treated with high-performance Teflon coatings are essential for a quality life. Management The legal person does not need to compensate for the bulb injury. High-quality and high-performance Teflon PFA coatings can be used at high temperatures for a long time, and the problem of lamp bursts can be solved.

Bulbs treated with high-performance Teflon coatings are not easy to break. Teflon is a registered trademark used by DuPont on PTFE Fusing Belts Factory a series of fluoropolymer products. Pedestrians will not scramble to avoid splashing glass. Roy Plunkett (Roy J. The 'nonstick pan' that saved countless modern housewives was born., which are all transliterations of Teflon. Subsequently, DuPont has developed a series of products in addition to Teflon? PTFE resin, including Teflon? AF (amorphous fluoropolymer), Teflon? FEP (fluorinated ethylene propylene resin), Teflon? FFR (fluoropoly Foam resin), Teflon? NXT (fluoropolymer resin), Teflon? PFA (perfluoroalkoxy resin), 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.

Na transfers the outermost electrons to the empty orbital of naphthalene to form anion radicals, and then forms an ion pair with Na, releasing a large amount of resonance energy, forming a dark green metal organic compound mixed solution. The basic design ideas of these methods are either to introduce polar groups to enhance the bonding force of the interface; or to eliminate the weak interface layer to form a strengthened surface layer; or to adjust the surface roughness to give an anchoring effect. The infrared spectrum shows that the modified PTFE surface introduces polar groups such as C=0, C:C, COOH, etc. Li Zidong et al. Studies have shown that the introduction of polar groups such as hydroxyl, carbonyl and unsaturated bonds on the surface of PTFE can increase the surface energy, reduce the contact angle, improve the wettability, and change from difficult to sticky.

This is the current research Among all the surface treatment methods, the effect is better and one of the more commonly used methods. At present, the sodium-naphthalene solution method is commonly used. Sodium-naphthalene solution is formed by dissolving or complexing sodium and naphthalene in active ethers such as tetrahydrofuran and ethylene glycol dimethyl ether. The results of these two studies show that the surface properties of PTFE have been well improved after this treatment.

These groups can increase the surface energy, reduce the contact angle, improve the wettability, and change from difficult to stick. These compounds have high reactivity. To be sticky, this is a more classic method with better practical effects. Commonly used surface modification techniques for PTFE include chemical treatment, high temperature melting, radiation grafting, plasma treatment and laser radiation modification [11]. Xu Baoguo used sodium-naphthalene solution to activate the PTFE surface, and analyzed the activated and unactivated PTFE surface with an electron energy spectrometer
