anodic zincous metallized 95 Alumina Ceramic insulating tube
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Oxidized ceramics can choose the following adhesives according to different needs:
1. G-977: One-component room temperature curing soft elastic shockproof adhesive, high and low temperature resistance, different viscosity bonding speed in a few seconds to a few hours to cure;
2. KD-833: Instant adhesive, 95 alumina tube it can quickly bond PC plastic in a few seconds or tens of seconds, but the adhesive layer is hard and brittle, and it is not resistant to hot water immersion above 60 degrees;
3. QN-505, two-component glue, soft glue layer, suitable for large area bonding or compounding of PC plastic. But the high temperature resistance is poor;
4. QN-906: Two-component adhesive, high temperature resistance;
5. G-988: One-component room temperature vulcanized rubber, after curing, the elastomer has excellent waterproof, shockproof adhesive, high and low temperature resistance, if it is 1-2mm thick, it will be cured in about 10 minutes and basically cured in 5-6 hours , There is a certain strength. It takes at least 24 hours to fully cure. Single-component, no need to mix, just apply after extruding and let it stand without heating.
Preparation
There are many production methods for ABS, which can be divided into four categories: blending, grafting, combined grafting and blending, and there are about eleven preparation processes. Nowadays, the emulsion method is mostly used, and the emulsion graft method is the most promising. ABS can produce products of various specifications by changing the ratio of three monomers and adopting different polymerization methods. Its structure includes graft copolymers with 95 alumina tube elasticity as the main chain and graft copolymers with resin as the main chain. The ratio of these monomers is roughly in the range of acrylonitrile 25% to 35%, butadiene 25% to 30% and styrene 40% to 50%.
Because PC/ABS is a blend of two polymers and PC is the main component, markings sometimes appear at the gate when processing products, usually due to the expansion of the melt into the cavity during high-speed injection. Caused by melt fracture. Starting from the molding process, measures such as increasing the material temperature, increasing the nozzle temperature, and slowing down the injection speed can be taken to reduce the appearance of PC/ABS product markings. It can also increase the mold temperature, add additional grooves, increase the gate size, and modify the pouring Mouth 95 alumina tube shape and so on. For example, fan-shaped gates are used for large thin-walled parts, and ear-shaped gates can also be used. An ear groove is added at the exit of the gate, so that the spray near the gate, the impact marks of material flow, and the residual stress are concentrated in the ear groove , Without affecting the quality of PC/ABS parts. At the same time, weld lines may also appear due to multiple gate injections or multiple runners.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
