GreenhouseSunshade AccessoriesIt Is The Core Equipment For Regulating Greenhouse Lighting And Reducing Temperature In Summer. By Blocking Direct Sunlight And Reducing Heat Input, It Creates A Suitable Growth Environment For Crops, Avoiding Problems Such As High Temperature Burns And Excessive Transpiration. At The Same Time, It Adapts To Different Greenhouse Types And Crop Needs. It Can Be Mainly Divided Into The Following Categories And Related Auxiliary Components:
Core Shading Material: The Basic Carrier Of Shading Function
Shade Net
The Most Commonly Used Sunshade Material Is Made Of Polyethylene As The Main Raw Material Through Weaving Technology, With Core Specifications (50% -90%) Divided According To "shading Rate", Suitable For Different Crop Lighting Needs:
Sunshade Screen
Suitable For High-end Greenhouses Such As Glass Greenhouses And Solar Greenhouses, It Is Divided Into "internal Sunshade Curtains" And "external Sunshade Curtains":
External Sunshade: Installed On The Outside Of The Roof Of The Greenhouse, Directly Blocking The Sun From Entering, With Significant Cooling Effect (can Reduce The Temperature In The Greenhouse By 3-5 ℃). Most Of The Materials Are High-strength Polyester Fibers, And The Surface Is Coated With Anti-aging Coating, With Strong Wind And Rain Resistance;
Internal Sunshade Curtain: Installed At The Top Of The Greenhouse, In Addition To Shading, It Can Also Reduce Heat Loss At Night (auxiliary Insulation). The Material Is Thinner And Lighter, And Some Parts Contain Reflective Layers, Which Can Optimize The Distribution Of Light Inside The Greenhouse And Avoid Uneven Light Exposure To Crops.
Supporting Drivers And Fixed Accessories: Ensuring Stable Operation Of The Sunshade System
Drive Equipment
Realize Automatic Retraction And Extension Of Sunshade Nets/curtains, Reducing Manual Operation, Mainly Divided Into Two Categories:
Electric Roller Shutter Machine: Used In Conjunction With A Scroll, Driven By A Motor To Rotate The Scroll, To Achieve The Unfolding And Folding Of The Sunshade Net. It Can Be Connected To A Timer Or Temperature Sensor And Is Suitable For Greenhouses Over 50 Meters In Length;
Manual Roller Shutter: Composed Of A Handle, Gear Set, And Steel Wire Rope, It Has Low Cost And Is Suitable For Small Greenhouses, But The Operation Is Laborious And Requires Manual Timing Adjustment.
Fixed And Supporting Components
Ensure That The Sunshade Material Is Securely Installed And Smoothly Retracted:
Sunshade Bracket: Mostly Made Of Hot-dip Galvanized Steel Pipes, Built On The Outer Side Of The Top Of The Greenhouse Or On The Crossbeam Inside The Greenhouse To Form A Support Frame;
Guiding Wheel And Track: Installed At Both Ends Of The Bracket, Guiding The Sunshade Net To Move In A Fixed Direction When Retracted, Avoiding Offset And Jamming. The Material Is Wear-resistant Plastic Or Metal, Reducing Friction Loss;
Compression Card And Strap: Fix The Edge Of The Sunshade Net On The Bracket Or Scroll. The Compression Card Is A U-shaped Plastic Buckle, And The Strap Is Made Of Polyester Material To Prevent The Sunshade Net From Being Blown Over Or Torn By Strong Winds.
