Technical field
The present invention relates to methane-generating pit field, relate in particular to a kind of nylon/polypropylene alloy and be used as the purposes of matrix resin in methane-generating pit raw material.
Background technology
Along with the progress of China's expanding economy, society, life of urban resident is further improved, but urban residents' life still exists a lot of problems.For building a well-off society in an all-round way, it is very necessary that building Socialist New seems.This rural ecological mode of agriculture of will seeking development, improves rural environment, increases farmers' income.Wherein fully utilizing methane-generating pit is exactly an important channel that changes rural environment.Build a methane-generating pit and can use about 20 years, comprehensive utilization is made good use of methane-generating pit not only can save energy, improvement and protection of the environment, saves in addition many benefits such as the output of chemical fertilizer and agricultural chemicals, raising farm crop and the development of quality, promotion and drive animal husbandry.
The raw material of methane-generating pit, by the most original brick and tile, has excessively arrived glass reinforced plastic, and has occurred the plastic material take polypropylene as resin matrix being most widely used at present.Acrylic plastering methane-generating pit excellent combination property not only frees construction of marsh gas tank personnel and managerial staff member from heavy manual work and complicated management work, has also accelerated to build pond speed, has guaranteed pool construction quality.But in the process of application, still there is following problem:
(1), in west area, because the morning and evening temperature difference is large, acrylic plastering methane-generating pit is owing to being subject to the easy stress cracking of impact of the temperature difference;
(2) in northern China and west area winter because temperature is very low, in pond, liquid freezes and causes methane-generating pit easily to be frozen cracking.
These defects greatly reduce the working life of acrylic plastering methane-generating pit.
