Description

聚丙烯丝网藻类附着基及加工方法
本发明涉及的聚丙烯丝网藻类附着基及加工方法，属塑料制品的加工，实际为采用废旧聚丙烯、聚乙烯旧丝进行重新加工应用于藻类养殖的附着基。
在我国海水藻类人工养殖生产中，长期使用的附着基是用棕树皮中加工出的丝为原料而混合成，用这种棕丝附着基，不耐磨，无拉力，费用高，易折断，使用年限短，不耐高温，在深水大流海区，经受不住大风大浪的冲击，断绳造成的损失相当大，严重制约了向深水大流海区发展，只能在内湾海区养殖，这种传统落后的藻类附着基已完全不适应再延续下去，近年来采用新聚乙烯丝与棕丝混纺和纯聚乙烯附着基，由于聚乙烯丝软性大，与棕丝合用，当棕丝受高温使用，逐渐断丝脱落，使附着基整体紧扣放松，第二年无法使用，纯聚乙烯纺成的附着基，紧扣松紧不好，松了夹不住小苗，使小苗脱苗率加大，紧了在人工夹苗时很困难，损伤小苗根部，影响根部发育，处理较好的使用一年后，第二年紧扣已全部放松，需要重新加工，这样投资大，费用大，影响保苗，损伤小苗，经济效益不高。
本发明的目的旨在改进上述不足，提供一种利用每年海上大面积养殖淘汰下的废聚丙烯网袋、聚乙烯旧丝，经重新加工，再利用到海上养殖的藻类附着基。
为了达到上述目的，本发明是在现有技术的基础上进行改进而实现的，其具有的工艺过程是选料、半人工成胚、成胚后合股纺成，其特点是选料采用海上大面积养殖淘汰下的100％的废旧聚丙烯沙网袋或60-65％聚丙烯沙网袋与35-40％的聚乙烯旧丝合成，利用人工或机械工具将沙网袋上残存的石头、海砾壳、扇贝壳或其它杂质砸碎清除掉，将沙网袋投入到打丝机进行拆袋(第一次打丝)后，重新投入打丝机进行第二次打丝，打丝后加水湿透，进行半人工成胚，成胚后合股纺成。
本发明利用废旧聚丙烯与聚乙烯旧丝重新加工，再利用到海上养殖中去。经试验表明，该附着基无毒性物质，抗磨耐用，拉力强，抗老化性强，费用低，使用年限长，附着基上带的泥沙杂物是良好的肥料，易于小苗抓根和促长。从总体效益看，与棕丝附着基相比，按棕丝三年的亩投入是1968元，而该附着基三年内不需重新加工，亩投入是630元，连续使用三年，每亩投入比棕丝节约资金1338元，是各种海水藻类养殖的理想附着基。
为了更好地理解与实施，下面以实施例说明如下：以山东沿海养殖为例，沿海每年用大批的聚内烯网袋进行自然海区栉孔扇贝、虾夷扇贝的采苗，用1-2年后，就丢掉了，每年约有几千吨被丢掉，变成废物，这些废旧聚内烯网袋因在海上使用1-2年已全无其它毒性物质，把丢在海滩上的废旧聚内烯沙网袋收集在一起，重新加工，再利用，取100％聚丙烯沙网袋，将寄生在沙网袋上的海砾石或留在袋内的各种贝壳等废物，用拖拉机压碎，轻者可采用人工用棒敲打，然后用工具杈筛翻，将杂物除掉，然后输送到打丝机互相撕绞拆袋，因沙网袋在投放海上采苗前，必须用缝纫机缝起来，袋口用绳扎起来，撕绞较费劲，打丝机可采用3-5KW、380V电机，入口通过两个对辊输入辊筒上带铁钉，通过两个对辊挤压，旋转时遇铁钉互相撕纹，辊与辊之间的沙网进行摩擦，将袋拆开，因第一次拆袋打丝不彻底，起毛率低，必须经第二次打丝，二次打丝后加水湿透，打捻，人工用压轮成胚，成胚后，最后合股纺成。
下面以聚丙烯与聚乙烯合成的附着基为例说明如下：
实施例1：选料取60％的聚丙烯旧丝，40％的聚乙烯旧丝；
实施例2：取65％的聚丙烯旧丝，35％的聚乙烯旧丝；
实施例3：取63％的聚丙烯旧丝，37％的聚乙烯旧丝，按上述比例选料以后，经去杂、拆袋(第一次打丝)、第二次打丝、加水湿透、半人工成胚、成胚后合股纺成。
按上面选料纺成的附着基可纺成系列品，系有：
Φ16mm-Φ18mm海带附着基；
Φ20mm-Φ25mm裙带菜附着基；
Φ25mm-Φ35mm羊栖菜附着基；
Φ4mm-Φ8mm海带育苗帘附着基。
因打丝后起毛率高，附着基夹各种藻类即不损伤小苗，苗夹的牢固，而且生产效果非常好。
