Iav Greenhouse Qhov Zoo Thiab Qhov Tsis Zoo

iav tsev cog khoom muaj ntau lub neej lub neej, thiab zoo nkauj tsos, yog li cov neeg feem coob nyiam lub iav tsev cog khoom, tab sis koj puas paub cov ncauj lus kom ntxaws qhov zoo thiab qhov tsis zoo ntawm iav tsev cog khoom? thaj chaw twg yog qhov tsim nyog los tsim iav tsev cog khoom?

Qhov zoo ntawm iav tsev cog khoom:

Glass greenhouse than ordinary PC sunshine board greenhouse light transmittance is high, light transmittance is about 90 percent , glass greenhouse overall aesthetic degree is good.  Glasshouse lasts longer than PC solar panel glasshouse.  In the absence of artificial destruction, glass greenhouse can still be used, but PC solar greenhouse solar board materials can be used for 10 years, good up to 20 years.  Good thermal resistance and uv insulation, wear resistance and durability, life up to 25 years.  Low coefficient of thermal expansion and cold contraction;  Fifth, the material is easy to take, the price is low  

Disadvantages is focus ont covering material glass: 

Lub shortcomings ntawm iav npog cov ntaub ntawv:

1） is poor collision resistance (except tempered glass);  

2） double glass is expensive (material plus sealing);  

3） the weight is large, steel needs to increase specifications and models;  

4） is fragile, not easy to clean up after broken;
