(2) cooling tank nozzle aperture of about 3.5mm pom stream of good quality plastic material, with water quenching is likely to cause shrinkage, which in time will become a problem extending water shrinkage results difficult to achieve the elimination of plastic materials pom stream glycerin bath temperature 80-100 ° C is appropriate. (3) the temperature of the plastic extending slot extending the glass transition temperature and melting point is related to the temperature is too low it can not extend uniformly, the temperature is too high so that too much stretching magnification is difficult to improve the strength and elasticity. Acetal copolymer POM plastic is 145-155 ° C glycerin bath, 6-9 times to obtain an extension of the length of the groove extending to about 2m as well, under such conditions, the resulting monofilament diameter of about 0.5mm. Stretching magnification is based on changes in the rate of change of the godet circumference extending around the groove ratio achieved. (4) annealing inside monofilament extending grooves remained strain annealing is required. Godet rate adjustment groove before and after annealing, so that monofilament line before the above tension is not affected. Annealing slot length lm about the stream as well pom plastic raw materials, and also extending slot as glycerin bath. (5) In order to wash after wash tank to be charged on the monofilament line starter, then annealed monofilament to rinse tank. Integrated chemical properties POM POM plastic materials resistant to the gas effects of performance pom POM plastic materials by atmospheric SO2, NO2 and ozone effects deterioration occur. Since the electrical contact is opened and closed under a closed state, will produce nitrous acid gas, so airtight Devices pom POM plastic materials will break down. Tested at 0.5X10-6 (0. 5ppm) ozone concentrations this stream pom plastic materials business, under the ozone concentration pom pom plastic materials is not a problem. The high concentration and high temperature state, degradation is likely to occur. For the closed state are: ozone conditions, it is necessary given attention.
