Description

A kind of production technology of anti-crack mortar

This application claims the priority of Chinese patent application 2021114349499 with a filing date of November 29, 2021. This application cites the full text of the above-mentioned Chinese patent application.

technical field

The invention relates to the technical field of anti-crack mortar, in particular to a production process of anti-crack mortar.

Background technique

Anti-cracking mortar is made of anti-cracking agent made of polymer emulsion and admixture, cement and sand mixed with water in a certain proportion, which can satisfy a certain deformation without cracking. It is mainly used for external or internal thermal insulation of external walls. Layer, the cover of the outer layer of polystyrene board, extruded board, etc., the existing anti-cracking mortar mainly has the following problems in the production process;

When using the elevator to transport raw materials, some raw materials have strong adhesion and are easy to stick to the inner wall of the elevator, resulting in that the raw materials cannot be quickly conveyed into the mixer, which is inconvenient to use and reduces the practicability of the device.

When drying the material, due to the thick accumulation of the material, the speed of heat entering the middle of the material is slow, which increases the drying time of the material, thereby increasing energy consumption and reducing the working efficiency of the device.

When the staff packs the anti-cracking mortar, the packaging bag is fixed on the sub-packing machine, and the overall weight of the packaging bag is relatively large after containing the anti-cracking mortar, which needs to be lifted by the staff to the conveyor belt, and then transported by the conveyor belt for stacking , It is easy to increase the work intensity of the staff.

Contents of the invention

The object of the present invention is to provide a kind of anti-cracking mortar production process in order to solve the above problems.

The present invention achieves the above object through the following technical solutions:

A kind of production technology of anti-crack mortar, it comprises the following steps:

Step 1: The staff mixes the raw materials by weight: cement: 25%-30%, coarse sand: 20%; fine sand: 40%; heavy calcium: 6%-7%; N2098 rubber powder: 1%; D40M : 2% and PP fiber: 0.12%, after these raw materials are measured by weighing scales, the raw materials are transported to the agitator through the hoist;

Step 2: Then add water to the agitator, and mix the raw materials through the agitator shaft in the agitator. During the agitation process, the staff can extract the agitated materials through the distribution tube on the agitator, so as to check the mixing status of the materials;

Step 3: Transport the mixed material to the drying box for drying. During the drying process, the humidity sensor in the drying box can detect the humidity of the material, and then display it on the display screen, which is convenient for the staff to adjust The temperature of the oven;

Step 4: The dried anti-cracking mortar is moved to the packing machine by negative pressure pumping, and the anti-cracking mortar is evenly filled by the packing machine.

Further, when adding the raw materials in the step 1, the raw materials need to be put in in batches, and cannot be put in all at once, so that the mixing of the raw materials can be made more uniform and sufficient, and the mixing time can be reduced.

Further, when adding PP fibers in the step 1, it is necessary to place the PP fibers in cement for dispersion, and the fine particles of cement can eliminate the static electricity of the fibers and disperse the fibers.

Further, when stirring in the step 2, the stirring time can be about 15 minutes, which can avoid long-time stirring that causes sand and cement to precipitate and stratify.

The beneficial effects of the present invention are:

The present invention can fix the vibrating motor on the hoist through the connecting plate and the vibrating motor, vibrate the raw materials attached to the inner wall of the hoist through the vibrating motor to make them fall off, and quickly transport the raw materials to the mixer, which is convenient to use , improve the usability of the device;

In the invention, the motor, the connecting shaft and the stirring shaft can drive the motor to stir the materials near the stirring shaft through the connecting shaft during the heating and drying process, so that the heat can quickly dry the materials and reduce the drying time and energy consumption. , improve the working efficiency of the device;

The present invention can place the packaging bag on the loading board by setting the slide rail, the sliding block and the bearing plate, and then after the filling is completed, the worker pushes the packaging bag, so that the packaging bag drives the bearing plate and the sliding block to move along the slide rail to Transport at the conveyor belt to reduce the working intensity of the staff.

Detailed ways

In this embodiment, when adding the raw materials in step 1, the raw materials need to be put in in batches, and cannot be put in all at once, so that the mixing of the raw materials can be made more uniform and sufficient, and the mixing time can be reduced.

In this embodiment, when adding PP fibers in step 1, it is necessary to place the PP fibers in cement for dispersion, and the fine particles of cement can eliminate the static electricity of the fibers and disperse the fibers.

In this embodiment, when stirring in step 2, the stirring time is only about 15 minutes, which can avoid the sand and cement sedimentation and stratification caused by long-time stirring.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
