NASA's job is to one day be able to send astronauts to asteroids or eventually to Mars, so NASA is also looking for new spacesuits to ensure the safety of astronauts while enabling them to move freely. Glue for wood door thickening composite process Composite glue - classification of composite glue

Scientists at the Massachusetts Institute of Technology say they are studying such spacesuits. A typical gas-pressure suit is more like a second skin because it is less bulky. Professor of aviation studies Dawa Newman said, “In traditional space suits, you basically provide the required one-third of air pressure in the balloon of gas, letting you live in a vacuum state of space, so we hope to achieve the same The pressure is applied directly to the skin through the mechanical back pressure, so that the gas pressure has the maximum fluidity, and the exploration of the planet is very light."
Newman has worked for 10 years and designed a fitting, flexible space suit. She uses the materials and techniques she needs to build a suit, not like bulky astronauts wear space suits that walked on the moon more than 40 years ago. This new technology can lead to a reduction in the weight of the space suit, which is more like a shrink-wrapped second skin.
1. Oily compound glue
Oil-glue compounding, also called glue compounding, is a kind of compounding. Generally speaking, it is relative to flame compounding. It is different from flame compounding in that it is not a layer of sponge but glue between the top fabric and the base fabric. Although the cost is lower than that of flame compounding, it has a harder feel.
2, pet compound glue
A special adhesive for thermal compounding made from thermoplastic polyester resin. It has excellent adhesion to PVC, PET, etc. It is synthesized from a single formula. It can be rolled after coating and drying. The thermal compounding temperature is low. It is suitable for high-quality PET and other materials compound products.
PVC composite adhesive refers to the adhesive that attaches PVC soft sheets to wood products such as MDF and plywood. Generally, it is made of high molecular polymer and resin. PVC composite glue is generally used for the production of PVC-coated wooden doors, panel furniture, etc.
4. Aluminized film composite adhesive
Aluminized film compound adhesive refers to the adhesive compound of PET and coated paper and other paper. Generally, the non-aluminized PET surface is coated with glue and then compounded with paper.
The aluminized film composite adhesive is generally a water-based acrylate polymerized emulsion. Strong adhesion to PET is required.
5. Metal composite glue
Also known as metal composite glue, bimetal composite glue, explosion-free metal composite glue, is a polymer polymer glue. It can be used for the composite between metal and metal, metal and plastic, MDF, synthetic board, stone, ceramics, glass, etc. The typical use is stainless steel foil (plate) or copper foil (plate) and cold-rolled metal door panel production. Composite of steel plates.
6. Water-based plastic-plastic composite adhesive
Water-based plastic-plastic composite adhesive refers to the water-based adhesive used for plastic flexible packaging composite. It is suitable for compounding between plastic flexible packaging BOPP, PE, PET, aluminized film, etc.
