化粪池模具仍然是方形的，顶部和底部稍小。如果分开，它们是上下两个梯形。在加工过程中，加工两个凹槽模型，将它们放在一起，成为一个成品。这种化粪池模具解决了传统化粪池模具不耐腐蚀、易渗漏和堵塞的缺点，但密封性不够好，抗压性也一般，无法生产大型产品。化粪池模具基本上是一个水平的圆柱体，但顶部和底部仍然设计成一个平面。车轮凹凸面封头开始使用。由于它是一个圆柱形模具，这一阶段的产品通常采用对接法连接和组合。该产品的抗压性能优于阶段，但产品的密封性可以得到改进，该产品的加工程序复杂，化粪池模具，又称波纹玻璃化粪池，是一种传统的化粪池，主要是砖混结构和钢筋混凝土结构。生产过程相对简单，没有技术内容，容易泄漏和堵塞，水处理效果不好。它污染了周围的环境，增加了下游污水处理厂的负担。施工程序复杂，施工周期长，不能满足施工方的要求。市场需要更合适的产品。手糊玻璃钢化粪池产品的外观不均匀，颜色不均匀。经过一段时间的使用，产品的外观发生了很大的变化，并开始出现分层、裂纹、剥落和渗漏现象。很难满足产品对强度、抗渗漏和防腐的要求。就这样，机械缠绕式玻璃钢化粪池应运而生。机械缠绕式玻璃钢化粪池具有抗压强度高、抗冲击、抗腐蚀、节能环保等优点，得到了各级环保和建筑部门的肯定和好评。
The septic tank mold is still square with a slightly smaller topand bottom. If they are separated, they are the upper and lowertrapezoids. During the machining process, two groove models arefirst processed and then put together to form a finished product.This kind of septic tank mold solves the disadvantages oftraditional septic tank mold which is not resistant to corrosion,easy to leak and blockage, but its sealing property is not goodenough and its pressure resistance is general, so it is unable toproduce large-scale products. The septic tank mold is basically ahorizontal cylinder, but the top and bottom are still designed as aplane. The concave and convex wheel covers are in use. Since it isa cylindrical die, products at this stage are usually joined andassembled by butting. The compressive performance of the product isbetter than that of the first stage, but the sealing property canbe improved. The processing procedure of the product is complicatedand the septic tank mold, also known as corrugated glass septictank, is a traditional septic tank, mainly brick-concrete structureand reinforced concrete structure. However, the production processis relatively simple, without technical content, easy to leak andplug, and the water treatment effect is not good. It pollutes thesurrounding environment and increases the burden of downstreamsewage treatment plants. In addition, the construction procedure iscomplicated and the construction period is long, which can not meetthe requirements of the constructor. Therefore, the market needsmore suitable products. However, the appearance and color ofhand-pasted FRP septic tank products are not uniform. After aperiod of use, the appearance of the product has changed greatly,and delamination, cracking, peeling and leakage begin to occur. Itis difficult to meet the requirements of strength, leakageresistance and corrosion protection of the product at the sametime. In this way, mechanical wrapped fiberglass septic tanksemerged. Mechanical wrapped fiberglass septic tank has theadvantages of high compressive strength, impact resistance,corrosion resistance, energy saving and environmental protection,and has been recognized and praised by environmental protection andconstruction departments at all levels.
