Problems solved by technology

[0003] Spraying technology mainly includes guest soil spraying, mixed spraying and hydraulic spraying. Plant fiber is indispensable in spraying technology. Traditional spraying materials include broken grass, rice husk, straw, etc., but spraying The resulting base layer is unevenly covered, and the operation is difficult; and the use of wood fiber can solve this problem well; in the spraying technology, it is necessary to add water to the wood fiber before spraying, so that the wood fiber must have a relatively high Only with good water absorption and softness can a base layer with uniform thickness be formed during the spraying process, and at the same time, an interlocking network structure is formed during the self-drying process to cover the spraying surface and effectively stick to the spraying surface. Combined, offset the scouring force of rainwater, and provide water and fertilizer at the same time, to ensure that the formed base is conducive to the growth of plants

Embodiment 1

[0064] A kind of wood fiber production method, comprises the steps:

[0065] S1: Material selection, choose wood with a diameter of 10-15cm or more; among them, the wood can be pine, willow, eucalyptus and other wood;

[0066] S2: Debarking, using a debarking machine to debark the selected wood;

[0067] S3: Washing, using water washing equipment to clean the peeled wood;

[0068] S4: slicing, using a chipper to cut the cleaned wood into flakes;

[0069] S5: Pre-cooking, use a swing sieving machine to sort the flake wood, put it into the preheating bin for pre-cooking, the pre-cooking temperature is 100°C, and the pre-cooking time is 5 minutes;

[0070] S6: Pressure cooking, put the pre-cooked wood in S5 into the cooking chamber for pressure cooking, the cooking pressure is 5.6bar, the cooking time is 3min, and the cooking temperature is 95°C;

[0071] S7: Grinding, putting the wood cooked in S6 into the heat mill 3 for grinding, grinding the wood into wood fibers; and stea...

Embodiment 2

[0082] This embodiment is basically the same as Embodiment 1, the difference is that:

[0083] In S5: pre-cooking temperature: 110°C, pre-cooking time: 8min;

[0084] In S6: cooking pressure: 6.2bar, cooking time: 4min, cooking temperature: 105°C;

[0085] In S9: moisture content: up to 17%;

[0086] In S11: spraying amount: 210kg / m³; spraying amount of water retaining agent: 6.5 kg / m³.

[0087] Wherein, in S8, the wood fiber is put into boiling water and boiled for 15 minutes, and the wood fiber is taken out after being soft.

Embodiment 3

[0089] This embodiment is basically the same as Embodiment 1, the difference is that:

[0090] In S5: Precooking temperature: 120°C, precooking time: 10min;

[0091] In S6: cooking pressure: 7bar, cooking time: 6min, cooking temperature: 110°C;

[0092] In S9: moisture content: 18%;

[0093] In S11: the spraying amount is: 220kg / m³; the spraying amount of the water retaining agent is 8kg / m³.

[0094] Wherein, in S8, the wood fiber is put into boiling water and boiled for 20 minutes, and the wood fiber is taken out after being soft.

Abstract

The invention discloses a wood fiber production method, which comprises: S1, material selection; S2, skin removal; S3, water washing; S4, slicing; S5, pre-cooking; S6, pressurizing cooking; S7, grinding; S8, softening; S9, drying; S10, air selection; S11, nutrient solution spraying; and S12, packaging warehousing. According to the present invention, the wood fiber produced through material selection, skin removal, water washing, slicing, pre-cooking, pressurizing cooking, grinding, softening, drying, air selection, nutrient solution spraying, packaging warehousing and other steps can be well used in spray seeding technologies; the wood fiber produced by the method has good softness; and during the spray seeding, when the wood fiber, the water and the binder are mixed, the wood fiber has good water absorption, such that each wood fiber can absorb a large amount of water so as to achieve good water content.

Description

technical field [0001] The invention relates to a fiber production method, in particular to a wood fiber production method. Background technique [0002] Spray seeding is a new technology suitable for afforestation of rock-soil slopes with a high degree of weathering and soil interbedded with rocks; Under the action of pressure, it is closely combined with the slope to form a substrate layer for plant growth and development. The requirement of soil thickness for spraying depends on the specific conditions of the slope, usually 10-30cm; bermudagrass, tall fescue, amorpha and other grass species must be added to the spraying to achieve the ideal in a short period of time. greening effect. [0003] Spraying technology mainly includes guest soil spraying, mixed spraying and hydraulic spraying. Plant fiber is indispensable in spraying technology. Traditional spraying materials include broken grass, rice husk, straw, etc., but spraying The resulting base layer is unevenly cover...
