Common types of thermal insulation quilts in greenhouse

The ideal greenhouse thermal insulation quilt should have the characteristics of thermal insulation, light transmittance, moisture resistance, ease of receiving and releasing, long service life and so on. With the rapid development of greenhouse planting industry, greenhouse thermal insulation is also gradually accepted by farmers. Below, let's take a look at the types, advantages and disadvantages of common greenhouse thermal insulation quilts.

Needle felt thermal insulation felt

[advantages] Needle felt thermal insulation felt is re-pressed with old broken thread (cloth) and other materials after certain treatment, with low cost and good thermal insulation performance. needle felt thermal insulation is used as the main cold-proof and thermal insulation material. on the other hand, the cooperation fabric between aluminized film and chemical fiber cloth can be used and made by stitching method, this kind of thermal insulation is heavier by its own weight, and has better windproof and thermal insulation performance.

[disadvantages] the biggest disadvantage of needle felt thermal insulation felt is its poor water resistance, but if it is shown that the Oxford rain cloth is used, it can be made into rain-proof thermal insulation quilt. In addition, before the thermal insulation is collected and stored, it needs a large place to dry. It can only be preserved after drying.

Composite thermal insulation quilt

[advantages] the composite thermal insulation is made of 2 mm thick honeycomb plastic film, plus 2 layers of non-woven cloth and stitched with chemical fiber cloth. It has the advantages of light weight and good thermal insulation performance, and is suitable for mechanical winding.

[disadvantage] the disadvantage of the composite thermal insulation quilt is that the honeycomb plastic film and non-woven cloth inside are easy to be broken after mechanical rolling.

Acrylic cotton thermal insulation quilt

[advantages] Acrylic cotton thermal insulation quilt is made of acrylic cotton and space cotton as the main materials against cold, non-woven fabric as fabric and stitching method.

Acrylic cotton thermal insulation quilt can meet the requirements in thermal insulation performance, but its firmness and durability is poor. After several times of mechanical winding and rolling, the non-woven fabric will be quickly damaged. In addition, because it is made by stitching, when it rains (snow), the water will seep into it from the needle hole.

Cotton felt thermal insulation quilt

[advantages] Cotton felt is used as the main material for cold protection, and both sides are covered with waterproof Kraft paper, and its thermal insulation performance is similar to that of needle felt. Due to the low price of Kraft paper, the price of this kind of thermal insulation quilt is relatively low.

[disadvantages] the service life of cotton felt insulation is short.

Foam insulation quilt

[advantages] the foam insulation uses microcellular foam as the main material, and the upper and lower sides use chemical fiber cloth as the fabric. The main material has the characteristics of light weight, softness, heat preservation, waterproof, chemical corrosion resistance and aging resistance. after processing, the thermal insulation quilt is not only long-lasting, but also excellent waterproof, easy to preserve and good durability.

[disadvantage] the disadvantage of foam thermal insulation quilt is that its weight is too light, so it is necessary to solve the problem of windproof.

Concrete thermal insulation quilt

[advantages] small thermal conductivity, good thermal insulation, especially when the temperature difference is large, low water absorption, good moisture-proof performance, good stretching and compression, easy to use, simple construction, suitable shape and size, tasteless and non-toxic.

[disadvantages] the second decoration is inconvenient, which is greatly affected by the outdoor climate. The temperature difference between day and night and the temperature difference between winter and summer are easy to cause wall cracking.

Fireproof and thermal insulation quilt

The fireproof and thermal insulation quilt is composed of fireproof cloth and aluminum foil on the upper and lower sides of the felt. A polyethylene foam layer can also be bonded between the felt and the fireproof cloth. The utility model has the advantages of reasonable design, simple structure, good waterproof and fireproof insulation, tensile resistance, mechanized transmission operation, labor-saving and labor-saving, and long service cycle.

Greenhouse thermal insulation quilt

Greenhouse thermal insulation is made of super-strong and high thermal insulation materials with multi-layer composite processing, which has the functions of light weight, waterproof, anti-aging, thermal insulation, far infrared reflection and so on. The service life can reach more than 5-9 years, and the heat preservation effect is good. Under the same conditions, the covering temperature can be increased by 10 degrees, and it is easy to keep and collect. The product is suitable for solar greenhouse, multi-span greenhouse, ecological restaurant, long-distance transport vehicle, plastic greenhouse and other thermal insulation cover, is the best substitute for grass and paper quilt.

Wool greenhouse thermal insulation quilt

100% wool greenhouse thermal insulation quilt has the functions of light weight, waterproof, anti-aging, thermal insulation and so on, with longer service life and the best thermal insulation effect. Wool leached water, has a good natural curl, can keep fluffy for a long time, in thermal insulation should be the first. High-quality, low-price manufacturers directly face the greenhouse growers, a wide variety of fabrics (optional), width 2. Rice. The length is done according to the actual length of the shed and is not wasted.
