The Prospect Analysis Of Straw Biologic Material Application In The Rural Housing Roof Insulation Layer In Hot-summer And Cold-winter Zone

Low-carbon and green development has become a consensus of countries in the world.The use of ossil energy overload causes that energy and environmental problems more serious,and it is a trend to develop the biomass energy.In the rural area,our biomass energy of straw is rich and has an advantage in light weigh,sound absorption,heat insulation and so on,so it is precious resources to the life of peasants and agricultural development.However,discarding straw casually and burning it away directly are serious,which go against the policy of Low-carbon and green devel-opment.It is an important social issue of a great deal of the biomass energy straw's development.Rural buildings are basically in a condition that they are built with no architectural design.What's more,it is not only lack of formal guidance of architectural technology,but also short of specific energy-saving rooftree standard of rural buildings.For the reasons given above,rural buildings are poor in thermal performance,especially in the rooftree,and they are in a state of energy consumption.Therefore,it is necessary for us to improve rural buildings' rooftree thermal insulation properties,and biomass energy of straw becomes an ideal heat preservation material of building rooftree.Firstly,the article is on a basis of earnest analysis of straw buildings' research results and existing experiment data domestic and overseas.Secondly,I visit and investigate typical village in Xin Yang so as to get the facts that thermal insulation properties of the rural housing roof insulation layer and the way to utilize straw.Finally,with the method combining theoretical analysis with experiment data,according to the mixing amount of straw,straw aggregate length,degree peeled stalks,straw,stover species specimen thickness and other factors,I make some test pieces and research their heat conductivity coefficient by JW-III conductometer to confirm their thermal insulation properties well or badly,and determine its final mixing ratio by compression testing.By the mean of researching straw test pieces' different proportion,such as sesame and maize,I can make sure the best fit mix proportion of rural housing roof insulation layer.In addition,I make an economic and convenient construction method,which can be popularized and used in the rural area,to achieve the goal that rural environment can be improved and energy consumption can be reduced.Further research on the actual promotion of this article discusses in detail the construction methods and straw roof insulation in hot summer and cold winter area of rural housing,apply effects to be.Moreover,the article also has some thoughtless factors.For example,if other kinds of straw roof insulation layer can achieve the same thermal insulation result or not,and if straw aggregating splice with cement bad can be solved by glue or not.These problems should be researched and solved further in future.
