Latex tube in the production when the sulfide and sulfide undersaturated how to deal with?
Latex tube production is a very confidential technical process, general manufacturers are not to give customers browse production process. So the general manufacturers in the beginning will have some problems more or less. For example, today is the day to understand topic: latex tube in the production when the sulfide and sulfide undersaturated how to deal with? That's a problem with one of the. Below small make up to share the next dry cargo.
First, the latex tube over the reason and the processing method of sulfide in produced
The general surface discoloration, perforations smaller, higher hardness, edge split products, due to improper operation, or the temperature is too high, the curing time is too long or instrument malfunction, check the valve and instrument if there is a problem, and to strictly enforce the rules of operation.
Second, the latex tube causes and treatment method of sulfide in produced less
Vulcanization is insufficient, the pressure is greater than the external pressure in the air after the model, compound if continue to pitting, ranging from low hardness, strong difference, large deformation; heavy hole blasting. Should check the meter, valve if there are problems, strict operation rules.
Note: silica gel tube foam products quality control index
(1) the apparent density, the smaller the better;
(2) the mechanical strength is generally 0.5-1.6Mpa;
(3) static compression permanent deformation;
(4) hardness;
(5) impact elasticity;
(6) the continuous dynamic fatigue;
(7) the aging test (70 degrees *70 hours; 100 degree *24 hours);
(8) and low temperature test.
