Embodiment 1

[0060] A mold for making a sand-fixing board connector, the structure of the sand-fixing board connector 13 is as follows figure 1 as shown in figure 2 As shown, the mold includes a piston member and a sleeve member, wherein:

[0061] The piston member includes a push rod 1, a first substrate 2 fixed on the bottom of the push rod 1, and a cross plate 3 fixed on the bottom surface of the first substrate 2, and the top of the push rod 1 is fixed with a first a handle 4;

[0062] The sleeve member includes a cylinder body 5 with both ends open, a second substrate 6 sealing one end opening of the cylinder body 5, and a sleeve 7 fixed on the top surface of the second substrate 6, the The push rod 1 extends into the barrel 5 through the sleeve 7 and the hole 12 on the second substrate 6, and a second handle 8 is fixed on the top of the sleeve 7;

[0063] The first substrate 2 is driven by the push rod 1 to move up and down in the barrel 5, the outer periphery of the first substr...

Embodiment 2

[0073] Embodiment 2 prepares magnesium cement mortar 16

[0074] The water in the following embodiments is not limited, it can be tap water or river and lake water.

[0075] 2.1 Preparation of magnesium oxychloride cement mortar

[0076] Described magnesium oxychloride cement mortar is prepared by following method:

[0077] Step 1, dissolving magnesium chloride in water to obtain a magnesium salt solution with a concentration between 20-30Be °;

[0078] Step 2, active magnesia, sandy soil (sandy soil is sand and / or soil, obtained from sand control locality) and described magnesium salt solution by mass ratio 1:(5-15):(0.5-1.5) (optimum ratio 1:8:0.9, in addition, 1:5:1.5, 1:15:0.5, 1:5:0.5) can also be used to mix and stir evenly to obtain magnesium oxychloride cement mortar.

[0079] 2.2 Preparation of magnesium oxysulfide cement mortar

[0080] Described magnesium oxysulfide cement mortar is prepared by the following method:

[0081] Step 1, dissolving magnesium sulfate...

Embodiment 3

[0090] Utilize the method for the magnesium cement mortar of embodiment 2.1, 2.2 or 2.3 and the mold described in embodiment 1 to prepare connector, may further comprise the steps:

[0091] Press down the first handle 4 of the piston so that it is close to the second handle 8 (as Figure 8 ), and then pressed into the magnesium cement mortar, this moment due to the pressure the mortar is filled into the cylinder 5 of the mold (as Figure 9 ), finally mention the first handle 4 of the piston part and maintain the position of the second handle 8, the whole mold is taken out from the magnesium cement mortar, and the first handle 4 is pressed down to make the connector of the present invention (such as Figure 10 ). The connectors are cured in the air for 8-36 hours (the best curing time is 24 hours) and then hardened. The curing temperature is generally 0-30°C (the best curing temperature is 20°C).

Abstract

The invention discloses a mold for manufacturing a sand fixation plate connecting piece, a preparation method and application. The mold comprises a piston piece and a sleeve piece; the piston piece comprises a push rod, a first substrate fixed to the bottom of the push rod and a cross plate fixed to the bottom surface of the first substrate, and a first handle is fixed to the top of the push rod; the sleeve piece comprises a sleeve body with openings in the two ends, a second substrate for sealing an opening in one end of the sleeve body and a sleeve fixed to the top surface of the second substrate, a rod body of the push rod penetrates through the sleeve and a hole in the second substrate and extends into the sleeve body, and a second handle is fixed to the top of the sleeve. The mold is simple in structure and convenient to popularize and apply, and the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of sandstorm prevention and control, in particular to a mold for making sand-fixing plate connectors, a preparation method and an application. Background technique [0002] The sand-fixing board is an important device for sand-fixing measures. The strip-shaped boards are arranged in the form of squares on the surface of the flowing sand layer to form a windshield wall, so as to reduce wind erosion and also intercept rainwater. Because of its certain The effect and low cost have been widely promoted, but the construction of sand-fixing boards on the sand surface is cumbersome, such as: [0003] The patent application number 201811353228.3 discloses "a silica sol modified cellulose-based binder, an environmentally friendly water storage type sand-fixing board and its preparation method", and its operation method is to embed the sand-fixing board in the form of a cross square On the sand dunes, this method not...
