近期随着冠状病毒全球蔓延,医用口罩供不应求,中国作为口罩出口大国,各地紧锣密鼓的加大投入口罩的生产,制造口罩机配套的空气压缩机也是起着至关重要的作用。特别是熔喷无纺布机用空压机

医用口罩一般采用多层结构,简称SMS结构:两侧为单层纺粘层(S),中间为单层或多层的熔喷层(M),熔喷层为口罩带来病毒过滤作用的主要材料,就是中间的熔喷无纺布简称熔喷布

熔喷布是口罩最核心的材料,熔喷布主要以聚丙烯为主要原料,通过螺杆挤出机使其熔融经过滤后从喷头的喷丝孔挤出,在喷丝孔出口处受到高速热空气流的喷吹,得到拉伸形成超细的短纤维,纤维直径可以达到1~5微米。空隙多、结构蓬松、抗褶皱能力好,具有独特毛细结构的超细纤维增加单位面积纤维的数量和表面积,从而使熔喷布具有很好的过滤性、屏蔽性、绝热性和吸油性。可用于空气、液体过

滤材料、隔离材料、吸纳材料、口罩材料、保暖材料、吸油材料及擦拭布等领域如:

(1)医疗卫生用布:手术衣、防护服、消毒包布、口罩等

(2)家庭装饰用布:贴墙布、台布、床单、床罩等

(3)服装用布:衬里、粘合衬、絮片、定型棉、各种合成革底布等

(4)工业用布:过滤材料、绝缘材料、水泥包装袋、土工布、包覆布等

(5)农业用布:作物保护布、育秧布、灌溉布、保温幕帘等

(6)其它:太空棉、保温隔音材料、吸油毡、烟过滤嘴、袋包茶叶袋等

制作熔喷布的螺杆挤出机,在加工过程中需要配套空压机为其提供气源动力,从而实现顺利生产,所以选择一台适合的空压机型号至关重要

首选需要考虑是否节能,省电

其次根据气量和压力选择适合的机型。气流量过高会导致机器瞬间启动气量过猛,空压机自动停机。气流量过低则会导致供气不足

最后选择具有《自有能效试验室》的空压机生产厂家,为购置新机增加一份保障
