1, the water-release fibre with required percentage by weight blows to by air-flow on the workbench of roll mill, and water-release fibre falls naturally to scatter and reticulates;
2, be evenly distributed on the netted water-release fibre that cloth is good on the roll mill workbench by the thermal fusing powder of the vibratory sieve on the workbench required percentage by weight;
3, repeat 1 and 2 steps up to the regulation technological requirement;
4, to 90 ℃～180 ℃, hot rolling or cold rolling go out water retaining penetration film produced by milling to roll mill through the heat baking.
Water retaining penetration film produced by milling of the present invention at first will be determined the raw material proportioning of water retaining penetration film produced by milling according to the soil condition of locality and the kind of the plant of being planted when practical application.Concrete example is as follows:
To be example in arid and semi-arid lands plantation Chinese pine, the raw material weight percentage of its water retaining penetration film produced by milling is:
Cotton fiber 12%;
Polyvinyl acetate 86%;
Low thermal oxidation agent 2%.
Its coating solution ingredients by weight percentage is:
Clay powders (granularity is smaller or equal to 0.2 millimeter) 25%;
Polyvinyl alcohol 8%;
Water 67%.
Three kinds of batch mixes are stirred, be heated to 85 ℃～90 ℃ simultaneously, make coating solution
Is to soak 60 minutes in 16% the sodium hydrate aqueous solution cotton fiber in concentration.The cotton fiber of alkalization being adopted concentration is that 5% glacial acetic acid solution soaked 30 minutes again.Cotton fiber after handling is soaked oven dry then in coating solution.Standby.Water retaining penetration film produced by milling is made in method hot rolling according to the 3rd step.
Through above-mentioned preparation method it is made and to make water retaining penetration film produced by milling, in use water retaining penetration film produced by milling is made water bag, at any water of on-the-spot can locality of planting trees, the water bag that will fill water then is positioned over the sapling root and afforests.Its modes of emplacement can be according to the kind difference of nursery stock, with water bag horizontal positioned or vertical the placement.Certainly the size and the quantity of water bag also are to do corresponding adjustment according to the kind of nursery stock.
Since water-release fibre be by native fiber through alkali, sour preliminary treatment, realize functional fibre after the functionalization coating with molecule water guide characteristic.Be mixed and made into water retaining penetration film produced by milling with this water-release fibre and thermal fusing powder.Utilize this water retaining penetration film produced by milling dress water to be placed on plant roots, the water formation water potential gradient outside the water-release fibre of the water in the film in film and the film in the soil is poor.Water-release fibre has the water guide function under the effect of water potential gradient difference, discharge hydrone along water-release fibre, and guaranteeing has a rational humidity in the plant soil on every side.For a single water-release fibre, what of institute's argillaceous directly influence the water transmitting ability of water-release fibre after the functionalization coating, and many water guides of content speed of clay is fast, clay contain that many water guides speed is slow less.In addition, can also control the overall rate of oozing out of water by the content that changes water-release fibre in the water retaining penetration film produced by milling, many water retaining penetration film produced by milling of content water guide speed of water-release fibre is fast, and the few water retaining penetration film produced by milling water guide speed of the content of water-release fibre is slow.Have, because water potential gradient difference and extraneous soil moisture content have direct relation, the speed of the more little infiltration of soil moisture is fast more again, and the speed of the big more infiltration of soil moisture is slow more, when soil moisture reaches 40% left and right sides, stops outside infiltration.Therefore the seepage velocity of water retaining penetration film produced by milling can be according to extraneous soil moisture content self-control.Above characteristic can guarantee plant surviving and survive in the arid and semi-arid lands.
The seepage velocity of above factor affecting water retaining penetration film produced by milling can adopt a unified parameter to weigh, and is exactly a day water percolating capacity, generally is unit with the gram.The general parameter that also adopts day water percolating capacity is just determined the packing water yield of different nursery stocks aspect afforestation.As table 1 is optimal design table at the seedling packing water yield of different nursery stocks or different seedling ages.
Because what the plastic film of water retaining penetration film produced by milling adopted is degradable polyethylene, contain the low thermal oxidation agent in the material because of degradable polyethylene, plastic film is at short notice with regard to degradable under the effect of low thermal oxidation agent, growth to plant can not impact, and has possessed environment protecting simultaneously yet.
The raw material proportioning of the above water retaining penetration film produced by milling only is preferable embodiment and the representational embodiment of the present invention; And the preparation method of described water retaining penetration film produced by milling only is the preferable preparation method of the present invention; The structure of described water retaining penetration film produced by milling also only is representational structure simultaneously; But protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
