The silicone material in the kitchen utensils is a popular cooking utensils. With the continuous development of the technology in the silicone industry, the hardware-coated plastic tableware has become a common species in the industry. It has been used in many restaurants and families in China. Silicone kitchenware items, and the use of hardware package silicone is currently a more used process in the silicone products industry, it can really guarantee the product for the plastic packaging method and process technology of tableware kitchenware!
The problem that hardware baggage is more serious when there are defective products and inferior defective products is the phenomenon of leaking hardware. If the hardware is used for a long time after the purchase, the more leakage will occur, such as the silicone spoon and tableware used directly. That will cause certain harm, so how to deal with the silicone rubber packaging process is a disadvantage, and the detailed processing of the silicone tableware is the main problem, then how to make the silicone package hardware process?
First, the hardware is divided into many types, and if there is a weak bond in the silicone rubber processing process, it may be because the hardware and the adhesive cannot be bonded. Generally, the bonding benefits are hardware, glue, rubber and processing agent. Several methods are used to practice, and the types of hardware are divided into different materials that require different compounding glues and bonding processes, such as anodizing of aluminum and its alloys, and copper plating of steel, which requires chemical methods. After the treated metal surface, the treated surface should be coated with adhesive, affixed with silicone rubber or immersed in an inert solvent.
Second, glue and treatment agent selection, glue is an important auxiliary material for hardware encapsulation, different materials choose different glue, and silicone tableware and hardware bonding need stronger liquid glue, need to stick silica gel and hard at room temperature Metal materials, treatment agents are of course important, the uniform application of the metal on the surface of the treatment will lead to partial sliding of the silicone kitchen utensils after long-term use.
Third, the product bonding method, different silicone tableware use different bonding methods, silicone kitchen utensils are usually divided into hot-pressing and cold-bonding process, the molding-fixing method is mainly formed after brushing the glue at high temperature. After the product is cured, the bonding effect is achieved. The cold bonding method is selected by liquid glue or mechanical bonding after static or high temperature drying. Different methods for this different silicone products have a certain structure with the silicone products. relationship!
Fourth， The structure and positioning of the product, the degree of the elastic effect of the bonding of the silicone product is closely related to the structure and the fixed position of the product, so the bonding area is increased as much as possible, and the bearing capacity of the bonded joint is increased in the direction of the force. The bonding length should not be too long, and the bonding width should be increased as much as possible. It is necessary to know that the bevel bonding is better than the right-angle bonding, and the plane is better than the beveled surface, so the product needs to be bonded as much as possible in the design. Good bonding points to find.
