Abstract
The permeable plastic film consists of two, one thin and ond thick, layers of plastic film with 400-800 holes in 3-5 mm diameter per square meter area. Two layers of film are crossed and adhered with the thick layer is outside one. When the permeable plastic film is used in green house and as mulching film rain water will flor downwards through the holes in rainy day, and the two layers are made to close each other by the vapor from the surface of soil to maintain moisture is sunny day. The present invention is suitable for use in drought area.
Description
The present invention relates to plastic products, specifically a kind of permeable plastic film.
No matter existing plastic sheeting is to be used in hot house, still is used as mulch film, when weather rains, rainwater all can not see through plastic sheeting and enter in the soil, makes that growing plants can not be effectively utilized rainwater in the hot house to come its required moisture is replenished, and must carry out the manual watering.Cause rainwater not utilize, must carry out the manual watering, not only taken a lot of work but also the phenomenon of water wasting.
The purpose of this invention is to provide a kind of rainy day can make rainwater enter in the soil, the fine permeable plastic film that is used for hot house and mulch film that evaporation from topsoil is reduced.
The concrete technical scheme that realizes the object of the invention is: permeable plastic film is double-deck, and one deck is thin, and a bed thickness has 400-800/m on every layer of plastic sheeting
2Diameter is the hole of 3-5mm, and two-layer stickup is pasted line and become rectangle, and arrange for dislocation in the hole, and thick-layer is positive.
The present invention is processed into following method:
(1), punching: select the existing plastic sheeting of thickness 0.08-0.10mm and 0.007-0.009mm, be introduced into the pair roller puncher, input hole spacing line-spacing carries out the pair roller punching, and the aperture is controlled at 3-5mm;
(2), to film: with above-mentioned two kinds of films that have openning hole, merge, make the hole on two films become dislocation to arrange during merging;
(3), heat posted: will introduce in the pair roller thermosticking film machine to good above-mentioned two kinds of films, to paste in form and the stickup line width scanning machine, and carry out the pair roller thermosticking film and handle, and paste line width and be controlled at 1-2mm, pasting line graph is ten son intersection rectangles, and the length of side is controlled at 50-60mm.
Characteristics of the present invention are that the infiltration hole can be opened under rainwater pressure and seeped water, water percolating capacity is big, and be exposed to the sun at the sun, when ground temperature is high, its closure is good, make that moisture is kept well in the soil, be applicable to that the kind grass in China the north, western drought and water shortage area is planted trees, use it can improve plant survival rate, change planted in the past many, kind is many, the situation that survival rate is low.

Embodiment
Permeable plastic film is made up of two layers of plastic thin films, one deck is thin, one bed thickness, on every layer of plastic sheeting, the hole that every square metre is opened 400-800 diameter is the 3-5 millimeter, two-layer stickup, pasting line is ten son intersection rectangles, arrange for dislocation in the hole, the thick-layer film is the front of permeable plastic film, when using like this, when water is on film, because being dislocation, the hole on the two membranes arranges, under the pressure effect of water, water can trickle downwards from the hole naturally, plays the infiltration effect, when weather sunny, when the sun is exposed to the sun, evaporation from topsoil steam makes progress, and at this moment double-layer films can be close together, and sealing is fine, make sunshine not volatile, effectively kept the moisture of soil the evaporation of surface water.
The processing and making process of permeable plastic film:
Select the existing plastic sheeting of thickness 0.08-0.10mm and 0.007-0.009mm, be introduced into the pair roller puncher, the spacing line-spacing of input hole carries out the pair roller punching, and the aperture is controlled at 3-5mm; With above-mentioned two kinds of films that have openning hole, merge, make the hole on two films become dislocation to arrange during merging; To introduce in the pair roller thermosticking film machine good above-mentioned two kinds of films, will paste in form and the stickup line width scanning machine, and carry out the pair roller thermosticking film and handle, and paste line width and be controlled at 1-2mm, pasting line graph is ten son intersection rectangles, and the length of side is controlled at 50-60mm.
