It is best to use epoxy tree -based adhesives. There are generally two components, which are now available. After sticking, it is slightly external forces. force. After a few more days, dry it and then use it. The oxygen resin adhesive is a type of engineering adhesive for epoxy resin base materials, curing agents, diluents, promoters and fillers. Because of its good bonding performance, good functionality, low price, and simple bonding technology, in recent decades, it has been widely used in the fields of home appliances, automobiles, water conservancy transportation, electronic appliances, and aerospace industries. The expansion data compared with other types of adhesives with other types of adhesives, with the following advantages: 1, epoxy resin contains a variety of polar groups and the activated epoxy base, so it is metal. , Glass, cement, wood, plastic and other polarity materials, especially materials with high surface activity have strong adhesion, and at the same time, the internal agglomeration strength of epoxy curing is also very high, so its glue connection strength is very high. Essence 2, epoxy resin is basically produced when there is no low molecular volatilization. The volume contraction rate of the glue layer is small, about 1%one and 2%, which is one of the most curing contraction in thermosetry resin. After adding the filler, it can be reduced to less than 0.2%. The inflation factor of epoxy curing is also very small. Therefore, the internal stress is small and the intensity of the glue connection is small. In addition, the creep of epoxy curing is small, so the size of the glue layer is good. rn3、环氧树脂、固化剂及改性剂的品种很多，可通过合理而巧妙的配方设计，使胶粘剂具有所需要的工艺性(如快速固化、室温固化、低温固化、水中固化、 Low viscosity, high viscosity, etc.), and the required use performance (such as high temperature resistance, low temperature resistance, high strength, high flexibility, aging resistance, conductivity, magnetic conductivity, heat conduction, etc.). 4, with a variety of organic matter (monomer, resin, rubber) and inorganic (such as fillers, etc.), it has good compatibility and reactivity, and it is easy to converge, cross -linking, mixed, filling and other modifications , To improve the performance of the rubber layer. 5, good corrosion resistance and good dielectric performance. It can corrodes a variety of media such as acid, alkali, salt, and solvents. The volume resistance rate is 1013-1016Ω · cm, and the dielectric strength is 16-35kV/mm. 6, universal epoxy resin, curing agent and additives have many production areas, large output, easy to formulate, can be exposed to pressure molding, and can be used on a large scale.
The main disadvantages of epoxy adhesives: 1. When it is not touched, the curing is generally brittle, and the anti -peeling, cracking, and impact resistance is poor. 2, small adhesion for materials with small polarity (such as polyethylene, polypropylene, fluoroplastic, etc.). Surface activation must be performed first. 3, some raw materials such as active diluents and curing agents have different degrees of toxicity and irritation. Try to avoid selection when designing formulas, and ventilation and protection should be strengthened during construction operations. Reference materials: Baidu Encyclopedia-Epoxy resin adhesive

1. After the jade bracelet is broken, you can use the adhesive (such as 502 glue, etc.), and you can go to the jewelry jewelry franchise store to help the master for help. There will be some small fragments (or small pieces). I wonder if you have collected uniformly. If you are not collected, there will be some "concave pits" after the bonding. On the one hand It also affects the aesthetics. Cracks after bonding are still visible. Professional use is a kind of instrument high -temperature glue without trace. 3. Go to the place to sell jade to repair professional people. It will be better. 4. Another way is to ask the master to use gold or silver to inlay the connection at the disconnection. The accuracy must be greater than the adhesion with glue, and it can cover the crack. More. Whether it is adhesive or inlaid with gold and silver bags, the bracelet is always damaged (disabled), which requires enough psychological preparation.

Jade can use slow glue
does not use 520 which chemical glue sticky, which glue is corrosive
n can be used by all kinds of glue, but the jade is broken. It is recommended that it does not need glue to dip the glue
It jade bracelets. If you break it, you can only make a choice of gold inlaid jade.
