Abstract
The utility model relates to a film-pressing strip for plastic greenhouse, which is mainly used for protecting the plastic film of the plastic greenhouse by blocking and pressing. The utility model is characterized in that the central reinforcing rib (1) of the film-pressing strip for plastic greenhouse is made of polypropylene material, and the outer coating layer (2) of the central reinforcing rib (1) is made of polyethylene material. The utility model has two types of film-pressing strips for plastic greenhouse, the cross section of one type film-pressing strip for plastic greenhouse is in a shape of a dumb bell, and the cross section of the other type film-pressing strip for plastic greenhouse is in a shape of a double dumb bell. The utility model has the advantages of high tensile strength, low breaking elongation, smooth and soft surface, no mechanical damage to the plastic greenhouse film, reliable blocking and pressing performance and low cost.
Description
The utility model relates to a kind of plastic tunnel press mold band, and the plastic film that is mainly used in plastic tunnel blocks the pressure protection.
The plastic tunnel technology has obtained increasingly extensive application in the most of regional agricultural production of China.But plastic tunnel in use, owing to be subjected to the effect of wind-force, its plastic film can not be attached on the skeleton of booth well, causes the canopy film to agitate up and down, and is very easily damaged, thereby influences growing of crops, total crop failure even.In recent years, materials such as common employing bamboo chip, iron wire, rope block the canopy film and press protection, but result of use is very poor.At first be that this class is blocked and pressed material to be easy to penetrate the canopy film to cause breakage, also exist the hurdle to press poor reliability simultaneously, use inconvenient, and shortcoming such as cost height.
Therefore the purpose of this utility model provides a kind of plastic tunnel easy to use press mold band, and this press mold band can not cause mechanical damage to the canopy film, blocks the pressure dependable performance.
The purpose of utility model realizes in the following manner.
Plastic tunnel press mold band has double-decker, and there is reinforcement the inside of band, and reinforcement has clad outward.Specifically promptly be with the center reinforcement of polypropylene material, with the external coating of polythene material as the center reinforcement as the press mold band.
Because press mold band inside is provided with polypropylene material, and polypropylene has higher intensity and lower tensile stretch, make the press mold band have good mechanical property, since the polypropylene reinforcement with polythene material as external coating, make the press mold belt surface smooth smooth, and and the canopy film between bigger contact area is arranged.
The plastic tunnel that the utility model provides has following advantage with the press mold band:
One, mechanical property is good.The tensile strength height, elongation at break is low, and tensile stretch is less than 15%.
Two, smooth surface, softness is big with canopy film contact area.
Three, plastic greenhouse film is not had any mechanical damage, block the pressure dependable performance.
Four, easy to use, cost is relatively low.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is the cross sectional view of a kind of press mold band of providing according to the utility model, and accompanying drawing 2 is cross sectional view of the another kind of press mold band that provides according to the utility model.
Plastic tunnel press mold band as shown in drawings is with the center reinforcement (1) of polypropylene material as the press mold band, with the external coating (2) of polythene material as reinforcement.
According to the actual conditions needs, the type of press mold band mainly contains two kinds, and is as shown in Figure 1 a kind of, and the shape of cross section of press mold band is dumbbell shape, have two center reinforcements (1) to lay respectively at the core of the capitate body at inferior bell two, between the capitate body with polythene material as connecting band (3).The tensile strength of this press mold band is generally greater than 1.0KN.
Another kind of press mold band.As shown in Figure 2, the shape of cross section of press mold band is two dumbbell shapes, have three center reinforcements to lay respectively at the core of the capitate body at two inferior bell two and middle part, between the capitate body with polythene material as connecting band (3), the tensile strength of this press mold band is generally greater than 1.5KN.
Reinforcement (1) adopts the high multiple oriented polypropylene material of high strength, low elongation.Generally speaking, all polypropylene materials all can use, and wherein the wire drawing grade polypropylene is best.External coating (2) adopts the polythene material of handling through ageing-resistant modification, and in fact all polythene materials all can use, and are best with blown film level polythene material wherein.
The size of press mold band.The thickness of reinforcement is 0.6-1 milli, and width is 1.8-2.2 millimeters, and the thickness of external coating is 0.2-0.6 millimeter, and the thickness of connecting band is 0.4-0.6 millimeter, and width is 1.8-2.2 millimeters.Cross section is that the width of the press mold band of dumbbell shape is 6-10 millimeters, and the width of the press mold band of two dumbbell shapes is 10-14 millimeters.Width as dumbbell shape press mold band is about 8 millimeters, and wherein the thickness of reinforcement is 0.8 millimeter, and width is 2 millimeters, and the thickness of external coating is 0.5 millimeter, and the thickness of connecting band is 0.5 millimeter, and width is 2 millimeters.
Claims (5)
1, a kind of plastic tunnel press mold band is characterized in that: with the center reinforcement (1) of polypropylene material as the press mold band, with the external coating (2) of polythene material as reinforcement.
2, by the described press mold band of claim 1, it is characterized in that: the shape of cross section of press mold band is dumbbell shape, has two center reinforcements to lay respectively at the core of the capitate body at inferior bell two, between the capitate body with polythene material as connecting band (3).
3, by the described press mold band of claim 1, it is characterized in that: the shape of cross section of press mold band is two dumbbell shapes, have three center reinforcements to lay respectively at the core of the capitate body at two inferior bell two and middle part, between the capitate body with polythene material as connecting band (3).
4, by claim 1,2,3 described press mold bands, it is characterized in that: the thickness of reinforcement (1) is 0.6-1 millimeter, and width is 1.8-2.2 millimeters, and the thickness of external coating (2) is 0.2-0.6 millimeter, the thickness of connecting band (3) is 0.4-0.6 millimeter, and width is 1.8-2.2 millimeters.
