The refractory layer uses a new type of material "ceramic silicon rubber", which is a new kind of polymer composite material. In the case of 750 c * 90min flame ablation, will not be burned powder ash, can form a hard ceramic shell, the role of insulation and fire insulation. And the higher the temperature, the longer the burn, the harder the shell. The material can be used as a cable refractory layer, and can be subjected to a certain spray and impact action. It has the characteristics of excellent electrical properties, good mechanical properties, according to the material performance of special process, we determine the diameter of 85 silicone rubber extruder on trial. In the trial production process, we found that the physical mechanical properties of tensile strength, elongation at break, there is always a case of failure. Therefore, in the trial, we have repeatedly adjusted its key operations, after repeated testing and testing, and finally succeeded. Fire retardant layer extrusion process is as follows:
1, to take out the cold extrusion, extrusion machine screw, machine head, body temperature to below 30 DEG C, a maximum of not more than 50 DEG C, cooling water temperature as low as possible; the body temperature is too high glue easily from sulfur, blocked nose.
2, the electric heating oven or oven in accordance with the first paragraph temperature: 160 to 180 DEG C, second temperature 165 to 185 DEG C, third temperature 170 to 175 DEG C, fourth temperature 175 to 180 DEG C, the last period of 200 to 230 DEG C temperature setting, heating, can also according to the different types of equipment and not with the structure of the cable set each curing temperature, the principle is the product of wire and Cable longitudinal sections without pores, no air bubbles produced, if there is bubbles, first of all to the first and two sections to reduce the temperature of 5 ~ 10 DEG C, gradually reduce the temperature 5 to 10 DEG C, until there is no bubble so far.
3, the production rate is the key parameter, directly affects the degree of vulcanization, according to the curing curve data after repeated verification, determined to be suitable for 10m/min or so, the beginning of the first slow, and then slowly speed. Can ensure the physical and mechanical properties of qualified.
4, extrusion die extrusion of the cable its good appearance quality, smooth surface, round the whole. According to the properties of the ceramic silicone rubber material, after repeated tests, finally decided to adopt the extrusion mold production, mold shaping segment length less than the ordinary rubber, suggest setting length, small cross-section wire shaping segment length 1.5-3mm, large section cable length 2-5mm setting.
5, mold polishing, in order to improve the quality of the appearance of the cable extrusion, ceramic silicone rubber mold must be polished before extrusion. If after polishing extrusion surface roughness, the adjustment between the extrusion die sleeve and core distance, at the same time, rubber extrusion should be slightly larger than the finished wire diameter of the die sleeve than ordinary silicone rubber wire and cable slightly smaller, and ultimay to the actual production of the commissioning shall prevail.
