Abstract

The utility model relates to a constant-temperature self-cleaning farm-oriented greenhouse membrane which is in a four-layer structure. The four layers are respectively an aging layer, a heat preserving layer, a self-cleaning layer, and a drop flowing layer from outside to inside and are all made of low density polyethylene. The heat preserving layer is a woven layer formed by intersecting warps and wefts. The constant-temperature self-cleaning farm-oriented greenhouse membrane has the advantages that a greenhouse is made of the low density polyethylene so as to be wear-resisting, endurable, low in cost, better in performance, stable in structure, degradable, environment-friendly, and free of pollution; the self-cleaning layer can enable the greenhouse membrane to maintain self cleaning; the drop flowing layer can constantly prevent drops and fog; the aging layer is good in weather fastness and can be used for 3-5 years; the four-layer structure is adopted so as to keep constant temperature inside the greenhouse, straw pads are not need adding on the greenhouse membrane for keeping warm, fuel for heating the greenhouse is saved, frost can be prevented, and crops are enabled to be ripe early and high in yield; and the proportion of the warps and the wefts of the heat preserving layer is optimized, and cross angles and diameters are proper so that the heat preserving layer wears well.

Description

The self-cleaning agriculture greenhouse film of constant temperature

Technical field

The utility model relates to the self-cleaning agriculture greenhouse film of constant temperature, belongs to the agriculture greenhouse film technical field.

Background technology

Horticultural covering film is widely used at agriculture field, need to add a cover straw mattress when horticultural covering film is in the market used or adopt the mode of firing equipment in booth, to keep canopy temperature constant, the inconvenience that this plants vegetables very for the peasant, and if run into frosty weather, for some frigolabile vegetables or fruit, what peasants need to be wasted time and energy heats in booth, processing procedure slightly has and delays, may cause the underproduction or the total crop failure of booth vegetable or fruit, this has brought very large trouble to peasants.

And heat-insulation layer warp parallel ratio of the prior art is improper, is not durable, and be only 1 year service life.

The utility model content

For solving the problems of the technologies described above, the utility model provides that cost is lower, constant temperature and the self-cleaning agriculture greenhouse film of good, the constitutionally stable constant temperature of self-cleaning property.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

The self-cleaning agriculture greenhouse film of constant temperature, be four-layer structure, is respectively from outside to inside: self-cleaning layer, aging layer, heat-insulation layer and drip layer, and four layer materials are low density polyethylene (LDPE), and heat-insulation layer is the braid that warp and parallel intersect.

Preferably, described warp and parallel ratio are 1-3: 1-3.

Preferably, the intersecting angle of described warp and parallel is 30-150 °.

Preferably, the diameter of described warp and parallel is 0.1-20 μ m.

The beneficial effects of the utility model are:

1) booth all adopts low-density polyethylene material, waterproof, fire-retardant, again can ultraviolet radiation resisting, and wear-resisting durable, cost is lower, performance is better, Stability Analysis of Structures, degradable, environmental protection is pollution-free;

2) the self-cleaning layer material can make horticultural covering film keep self-cleaning;

3) the drip layer can be antidrip, antifog lastingly;

4) aging layer weather resistance is good, and can reach 3-5 service life;

5) adopt four-layer structure, daytime, sunshine saw through horticultural covering film, enter in canopy, can absorption as much as possible and store the heat of sunshine, go out thermal release evening, use this horticultural covering film, can keep canopy temperature constant, save for warming and add a cover straw mattress on horticultural covering film, also save the fuel of heating greenhouse, frost be can effectively prevent, crop precocity and high yield made;

6) heat-insulation layer warp parallel ratio optimization, intersecting angle and diameter are suitable, durable in use.

The tricot machine that the utility model is used is HKS3 series tricot machine.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with embodiment, the utility model is further described.

The self-cleaning agriculture greenhouse film of constant temperature, be four-layer structure, is respectively from outside to inside: self-cleaning layer 1, aging layer 2, heat-insulation layer 3 and drip layer 4, four layer material are low density polyethylene (LDPE), and heat-insulation layer 3 is the braid that warp 31 and parallel 32 intersect.

Described warp 31 and parallel 32 ratios are 1-3: 1-3.

The intersecting angle of described warp 31 and parallel 32 is 30-150 °.

The diameter of described warp 31 and parallel 32 is 0.1-20 μ m.
