Product Description
Description
Pneumatic rubber mandrel is a kind of cylinder bag that can expand, shrink, used to form concrete component of cavity.
Performance characteristic
1. Design scientific and reasonable used inflatable rubber mandrel, or casting parts, finished product can meet the requirement of design, easy operation, save time, save material.
2. Have good ageing resistance performance and long service life this product use synthetic rubber ,natural rubber and strengthen layer vulcanize, Has very good resistance to bulge, flexibility and elasticity so can satisfy all sorts of work in the conditions of use.
3. Widely applicable temperature, within the scope -10ºC-+90ºC of the material without change .
4. For building light-duty construction provides favorable conditions to stress hollow concrete. Component, due to the rubber mandrel ,the weight than use stress solid component light 20%,so it can reducing the weight of the upper structure of building .can make the pipe foundation short. increase span, make the construction become simple and safety.
5. construction technology is simple ,safe, health, use it only need a few simple tools, without special process.
