八四年十二月国内首次引进的三元乙丙一丁基橡胶防水卷材挤出——硫化连续生产线,经验收在我厂投产。设计能力年产七十九万米~2。这条生产线采用冷喂料,经L型机头口型板挤出片材,通进间接蒸汽加热的密封高温硫化箱,连续硫化和冷却,卷取成宽1.2米、厚0.8～2.0毫米成品卷材;挤出——硫化用直流电机传动,硫化深度可调。结合冷喂料挤出及高温硫化的特点,在原生产配方基础上,对硫化系统、防老化系统,补强和软化系统进行了调正和改进、使胶料的烧焦时间长,硫化速度快,并采用了两段混炼工艺,提高了混炼胶质量。这条生产线从验收投产到八六年十二月
In December 1984, the first EPDM-butyl rubber waterproof roll extrusion-successive vulcanization production line was introduced in the country and the experience was put into production at our factory. The annual output capacity is 790,000 meters~2. This production line adopts cold feed, extrudes the sheet through the L-shaped die plate, passes through the sealed high-temperature vulcanization box heated by indirect steam, continuously vulcanizes and cools, and coils into a width of 1.2 meters and a thickness of 0.8 to 2.0 millimeters. Coil; Extrusion - vulcanized DC motor drive, adjustable depth of vulcanization. Combining the features of cold feed extrusion and high-temperature vulcanization, based on the original production formula, the vulcanization system, anti-aging system, reinforcement and softening system were adjusted and improved, the curing time of the rubber material was long, and the vulcanization speed was fast. And using two mixing processes to improve the quality of the mix. This production line was inspected and put into production until December 1986
