氢氧焊机是正在研制的新型焊机,它具有广泛的用途:可用于气焊、气割、钎焊、电弧焊、蓄电池充电、给氧给氢装置。由于该机体积小,装有小轮,可以灵活移动,使用方便。因而可用于工厂、矿山、农村、海岛、部队修械所作生产与维修之用,同时还可作为供氢供氧气源使用。还可解决对电石和氧气钢并供应不足的问题,用以代替乙炔气焊,可以防止空气污染,有利于安全生产和方便人民生活。三元乙丙橡胶是乙烯、丙烯、二烯烃的三元共聚物。二烯烃主要有双环戊二烯(D型)、乙叉降冰片烯(E型)和1、4-已二烯(H型)。三元乙丙橡胶具有 Hydro-oxygen welding machine is a new type of welding machine under development. It has a wide range of uses: It can be used in gas welding, gas cutting, brazing, arc welding, battery charging, oxygen supply hydrogenation device. Because of the small size of the aircraft, equipped with small round, you can move, easy to use. It can be used for factories, mines, rural areas, islands, military repair for the production and maintenance purposes, but also as a hydrogen source for the use of oxygen. It can also solve the problem of insufficient supply of calcium carbide and oxygen steel instead of acetylene gas welding to prevent air pollution, facilitate safe production and facilitate people’s life. EPDM rubber is ethylene, propylene, diene terpolymer. Dienes are mainly dicyclopentadiene (D type), ethylidenenorbornene (E type) and 1,4-diolefin (H type). EPDM has
