Polyoxymethylene with improved resistance to acids, process for their preparation, as well as employment stability.

摘要

2.1. Polyoxymethylene (POLYACETAL) is an excellent material, from which MANUFACTURED USING PARTICULARLY RIGID OBJECTS WITH HIGH ACCURACY. HOWEVER polyoxymethylene is sensitive to acid. The object of the present invention to obtain a polyoxymethylene stabilized THIS ALLOWS ACID AND INJECTION CASTING MOLD BODIES INCLUDING FINE OR GRAIN threadlike structure. 2.2. By adding cyanurate MELANINA polyoxymethylene Stabilizing AGAINST ACID ATTACK WHERE ARE ACTIVE IN PARTICULAR FORM OF THREE PARTS LOWER MCA 100 parts POM. WEIGHT LOSS POM STABILIZED IN EFFECT CAN BECOME ACID less than 3% AGAINST A unstabilized POM. 2.3 UTILIZATION FIELDS IN WHICH PRODUCTS ARE EXPOSED TO AGENTS ACIDS, SUCH FACILITIES ARE WASH, RINSE FACILITIES, SANITARY FIELD.
