Cause analysis
(1) Natural rubber moisture and volatile matter exceeds the standard
(2) chemical raw materials and additives storage, batching and other aspects of moisture moisture increase.
(3) Steel cord moisture, coated steel wire slurry is not dry.
(4) Fibre cord moisture back rate is high, the original line is higher than 2%, before calendering is higher than 1%.
Solution measures
(1) natural rubber cut rubber after taking baking measures, to control the moisture and volatile matter according to the standard, is strictly prohibited to exceed the standard, reduce the moisture content of the original rubber.
(2) chemical raw materials and additives storage to increase moisture-proof measures, in the rainy season and rainy season, foggy weather, especially to help transport, storage, processing and other aspects of the raw materials to avoid moisture, wet. Match the raw materials with plastic containers to feed.
(3) Steel cord in the use of 1 hour before the opening of the package, to maintain indoor humidity does not exceed the standard, to avoid moisture wire cord, steel wire coated with glue paste after blowing dry.
(4) Fibre cord heating and drying before calendering, cord into the calender before the moisture back rate of less than 1%.
