Rocket Propellant Coating Ethyl Cellulose
Ethyl Cellulose K70 K100 for rocket propellant coating band
Basic composition and process method of coating material
The emitter coating material uses organic ablative coating heat-resistant materials, and organic ablative coating heat-resistant materials generally do not have universality. Basically, the applicable research should be based on the environmental conditions that the material is subjected to. Material system. Some environments hope that coating materials have excellent thermal insulation performance, some environments hope that coating materials have excellent erosion resistance, and some environments hope that coating materials have both.
The coating materials used on the solid rocket motors of the anti-tank weapon system currently include two types: high temperature molding and normal temperature molding, and the two application environments are quite different. The focus of research on ablation-resistant and erosion-resistant coating materials as a transmitter includes two aspects. One is the basic composition and basic properties of the coating material, and the other is the molding process conditions of the coating material. That is to say, after the composition of the coating material is determined, the molding process method becomes the main factor that affects the structural performance of the coating.
Name: Ethyl Cellulose
In the formula , n stands for degree of polymerization and R for –H or –C2H5 .
Ethyl Cellulose is a kind of white grains or powder, having no smell or tastes . Its 5% soliquoid shows neutral to litmus test paper . Its specific density 1 . 07~1 . 18 , heat distortion point: 135~155degree centigrade , and fire point: 330~360 degree centigrade . Ethyl Cellulose has good stability to light , heat , oxygen and wetness , and is stable to chemicals . It is resistant to alcali , dilute acid and salting liquid , soluble in some organic solvents , such as alcohol , ether, ketone , ester, aromatic hydrocarbon and halohydrocarbon , etc , and compatible to many celluloses , resin and nearly all plasticizers . Ethyl Cellulose has low combustibility, small hydroscopicity and good electric behavior . Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature .
