II. Main Technical Specification::



Ⅲ、Methods of application:
1st,surface treatment:Eliminates the rust,eliminates the welded joint,the burr,the oil,the contamination and is dry,Manually should reach the St3 level except the rust,the machinery should conform to in the SYJ4007-86 St2 level except the rust.
2nd,spreads the stereotypia rubber:Armor,second grade component stereotypia rubber according to 1:1proportion mix,after stirs evenly spreads brushes,the request spreads spreads evenly,is full,cannot leak spreads.
3rd,twines the baseband: After the stereotypia rubber spreads twines the baseband immediately,must maintain the stereotypia rubber the tacky state,if the stereotypia rubber spreads brushes the time long since to work,must again spread brushes and only then belt tied over the clothing,after the baseband entangles spreads stereotypia rubber again And stereotypia rubber→baseband→stereotypia rubber or + stereotypia rubber.
4th,the construction condition must achieve ventilates good,is far away the open fire.

Ⅳ、Transportation and Storage:
1st,when transportation should lightly unload with light packs,prevented the rain drenches,avoids sunlight The storm exposes to the sun.
2nd,storing in cool,is dry,ventilates,is sure not to be close to the fire hazard,the biggest 4 ramparts put,storage time six months.
