LOGO sandblasting special heat release protective film

At present, there is no standard product on the market specifically named "LOGO sandblasting special heat release protective film". However, your needs can be met through two mainstream solutions: one is liquid anti sandblasting ink, and the other is solid thermal release protective film. They each have their own emphasis on craftsmanship, precision, and effectiveness.🎨 Solution 1: Anti sandblasting ink - high-precision logo solutionIf your core requirement is to create high-precision logo patterns, then anti sandblasting ink would be a more precise choice. This method is widely used in scenarios such as high gloss LOGO processing on mobile phone metal frames and aluminum alloy product surfaces.Working principle: A hard protective layer is formed on the surface of the substrate through screen printing, exposure development, or spray coating processes. This layer of ink can withstand the impact of sandblasting, protect the areas that need to be preserved, and achieve precise etching of logos or patterns.Core advantage: High precision, photosensitive development ink can achieve a resolution of 20 μ m, fully meeting the production needs of fine logos. The curing time of UV curable ink is only 5 seconds, suitable for large-scale production.Removal method: After sandblasting, it can be soaked in dilute alkali solution (such as 5% NaOH solution) or mechanically peeled off without leaving any residue.Key parameters: Impact resistance of approximately 0.2-0.5MPa; The ink film layer has high elasticity and sand resistance.Supplier reference: Shenzhen Wanjia Yuan Fine Chemical Technology Co., Ltd. is one of the suppliers of this type of ink.🛡️ Option 2: Thermal anti sticking protective film - convenient overall protectionIf considering the use of solid film, it is mainly used for masking and temporary fixation before sandblasting, rather than directly as logo ink. For example, sticking a logo masking film on aluminum alloy products before sandblasting is a typical application.Working principle: Maintain viscosity at room temperature, used to protect or fix workpieces. After processing, by heating to a specific temperature (such as 100 ° C to 180 ° C), its viscosity will sharply decrease (foaming peeling), making it easy to remove.Core advantage: No residual glue is its most prominent advantage, and it will not contaminate the surface of the protected object after heating and peeling. Easy to use, can be peeled off after processing.Key parameters: The conventional adhesion force is relatively high at room temperature and decreases to about 0.02N/20mm after foaming; The peeling time usually ranges from 10 seconds to 5 minutes.In addition to thermal anti adhesive protective films, traditional sandblasting protective films (such as PVC materials) used for sandblasting protection are also widely used, especially for large-area protection.🔩 Key Process and Structural AnalysisComparison of core processes:Anti sandblasting ink process: cleaning → silk screen printing/spraying ink → curing (UV or hot air) → sandblasting → peeling.Protective film process: cleaning → film application (cold/hot pressing) → sandblasting → heating peeling.The structure of sandblasting protective film is usually a three-layer composite structure, including the surface layer, middle layer, and adhesive layer. For example, a common structure is: PVC film+gelatin (water-based adhesive)+release paper

PET double-sided tape, stretch resistant double-sided tape

PET double-sided adhesive tape "usually refers to a double-sided adhesive tape made of PET (polyester film) as the substrate, which combines high tensile strength and strong adhesion. The "pull resistance" of this type of tape is mainly reflected in two core indicators:Tensile strength: The maximum tensile force that the tape itself can withstand, usually measured in N/cm. The higher the value, the stronger the tape, and the less likely it is to break when stretched.Adhesive strength (such as peel force, shear force): The degree of firmness of the tape after it is adhered to the surface of an object. Even when subjected to force and pulling, excellent adhesive performance ensures that the tape will not separate from the adhered objectKey points for purchasingWhen making a purchase, in addition to comparing parameters, you also need to pay attention to these four points:Clarify the requirement for "tensile resistance": Do you need resistance to physical tension or shear force? Tensile strength and shear strength are two different concepts.Evaluate the usage environment: Do you need high temperature resistance? Long term temperature or short-term temperature? For example, 3M 9019 has a short-term temperature resistance of 121 ° C and a long-term temperature resistance of 82 ° C, while tesa 68575 has a short-term temperature resistance of up to 200 ° C.Determine the material of the adhesive: The adhesive strength of the tape to specific materials (such as low surface energy plastics PP/PE, metals, PET, etc.) may vary, and the product technical parameter table needs to be checked.Consider processing technology: If it is necessary to die cut into a specific shape, the substrate strength (such as tesa 68575) and die cutting performance of the tape are key considerations.summarySimply put, the "tensile" performance of PET double-sided tape is a comprehensive reflection of the tensile resistance of the tape substrate and the adhesive bonding ability. Choosing the right product for your application scenario is essentially finding the optimal balance between tensile strength, adhesive strength, thickness, and environmental resistance
