贴片式和迷宫式滴灌带的优势比较 The advantages of the patch and the maze drip irrigation 1）滴头流道设计： 1) drip design: （1）贴片滴灌带采用先注射滴头贴片，再挤出塑料管粘贴滴头工艺，贴片滴头流道形状，可以根据滴水均匀性、抗堵塞性采用不同的设计。更换模具就可以得到，不同水利用性能的滴灌带，甚至还可以做成补偿式滴灌带，实现精细化灌溉非常容易。 (1) patch drip irrigation belt adopt injection head strips, then paste extrusion plastic tubing head technology, patch drops head groove shape, can according to the water uniformity, anti-clogging in different design. The change of the mold can be obtained, different water use the drip irrigation belt of the performance, even can make compensatory drip irrigation belt, realize refined irrigation is very easy. （2）迷宫式滴灌带采用成型轮成型，由于成型轮设计和制造都比较繁琐，成型轮的结构形式决定了，不可能制造出高精度水利性能滴灌带，只能进行粗放式节水灌溉，要实现精细化灌溉相当难。 (2) the labyrinth drip irrigation belt is made of molding wheel forming, due to the forming wheel design and manufacturing are tedious, forming the structure of wheel determines, impossible to produce high precision hydraulic performance of drip irrigation belt, only vulgar water-saving irrigation, quite difficult to implement sophisticated irrigation. 2）抗堵塞性 2) blocking resistance （1）贴片式滴灌带，通水后为圆形管状，在铺设时可以人为的让滴头出水口朝上，当通水时，万一过滤不好，水中含有杂质，由于杂质的比重大于水，杂质会沉在滴灌带的底部，远离滴头，不会造成滴头堵塞。 After drip irrigation belt (1) patch type, drainage systems for the circular tube, can people let drop when laying head outlet up, when the water, one thousand filter is not good, the water contains impurities, due to the proportion of impurity is greater than the water, impurities will sink to the bottom of the drip irrigation belt, away from the head, will not result in a drop head congestion. （2）迷宫式滴灌带由于有侧翼，无法像贴片滴灌带那样，让滴头出水口朝上。通水后，迷宫滴灌圆管的侧翼滴水口自然朝下，当水中含有杂质，由于杂质的比重大于水，杂质会沉在底部，涌向滴头，造成滴头堵塞。 (2) the labyrinthine drip irrigation belt, which has flanks, can not be like a patch of drip irrigation. Drainage systems, to the side of the labyrinth drip irrigation pipe mouth dripping down naturally, when the water contains impurities, due to the proportion of impurity is greater than the water, impurities will sink in the bottom of the flock to drop head drop head congestion. 3）使用年限 3) use fixed number of year 滴灌带的使用年限，在材料性能相同情况下，不同的厚度，决定了滴灌带的使用年限和寿命 The use age of drip irrigation belt, in the same condition of material performance, different thickness, determines the service life and life of the drip irrigation belt （1）贴片滴灌带可以根据需求，分别生产0.2-0.6mm不同厚度的滴灌带。 (1) the drip irrigation belt of the patch can be produced according to the requirement, the drip irrigation belt of different thickness of 0.2-0.6 mm respectively. （2）迷宫式滴灌带由于工艺的要求只能生产0.2mm厚度的产品。 (2) the maze drip-irrigation belt is required to produce only 0.2 mm thickness products due to the process requirement. （3）由于贴片滴灌带，可以根据作物的要求的使用年限，生产不同厚度的滴灌带。从这个方面讲，贴片滴灌带使用年限可以长一些。 (3) because of the drip irrigation belt, it is possible to produce the drip-irrigation belt of different thickness depending on the length of the requirement of the crop. In this respect, the patch will last longer.
