The cotton spinning coarse sand process is safe, please the process in the textile factory, what kin

Spun stopper.

It is a process from coarse sand to spinning.

winding. in the spinning process.

It's hard to put into words, from.

DAO--- from mechanical transmission of special motion--- drafting --- molding genus--- from different raw materials to different finished products, from different processes of different operation methods... Wait a minute!

I think you'd better go to the bookstore and buy books on that. Small bookstores don't necessarily have them. Or go to the library.

No, it's nothing to build a wall, it's mainly plastering. If you want to make ash cakes, punch and hang lines, find the construction plan on the Internet! Can't say!

There are coarse sand and fine sand in the furniture factory process category. Coarse sand refers to the fact that when the furniture board is finished with a primer and dried, the board is coarsely sandpapered, simply put, it is to polish the board with the primer, and this process is a simple sanding. The next process after simple treatment is fine sand, that is, fine grinding.

Coarse sand, depending on whether it is recruited by the carpentry department or the paint department. The carpentry department is the wood mill, if the ash part is the ash mill, it is the ash mill, and the paint department is the base mill. Anyway, the body is not very good. There is dust.

There are mostly two kinds of cotton spinning mills in China, ring spinning and rotor spinning.

The more detailed is the mechanical combination of each process, which can be more or less.

Coarse sand is generally not used in home decoration, fine sand is used to paste wall tiles, medium sand is used to pave floor tiles is the best, coarse sand and fine sand are not the same, mixed to reduce costs. The wall cement is painted with medium sand. The amount of cement and sand that the master said is fine.

Tile paving methods and steps.

1. First of all, clean the back of the pre-selected tiles and soak them in water for more than 2 hours. The purpose of water immersion is to allow the tile to absorb enough water in advance, so as not to absorb the moisture in the adhesive material after paving, affect the bonding strength or cause the adhesive material to shrink excessively and cause hollowing, debonding, etc. After the tile is soaked in water, it should be removed from the water before paving, and the surface moisture should be wiped off with a cotton cloth or the surface moisture should be dried before paving.

2. Before the start of paving, the vertical line should also be hung on the wall leveling layer to determine the size line of the tile out of the wall, and pull the horizontal line, so that the surface can be smooth when paving, and the tile can be horizontal and vertical. Ensure that the base surface should be firm, smooth, clean, no pollution, loose matter, hollow, etc., with curing agent, release agent, smooth concrete surface needs to be polished and rough after construction.

3. Add about 7 water with 25kg of Lejiang tile adhesive powder, stir it into a uniform and particle-free mortar with an electric mixer, and leave it for 3 5 minutes and stir again. The adhesive material should not be too thick, otherwise it is not easy to spread out, and it should not be too thin, otherwise the tile paste cannot be fixed and it is easy to fall.

4. Use a toothed scraper to evenly scrape the glue on the working surface, scrape about 1 each time, and then knead the tile on the working surface.

5. If it is used for ceramic tiles or stones with deep back grooves, the toothed scraper should also be used to wipe the glue on the back of the brick to ensure that the paste is full.

6. According to the pollution of the whole tile wall, the surface can be scrubbed with clean water.

In fact, both coarse and fine sand can be used. However, the coarse sand + fine sand is better mixed, and the continuous gradation is more solid.

Coarse sand + fine sand is better mixed, which can cause continuous gradation and more solid. It is equivalent to the use of medium sand.

Fine sand is better.

Too thick floor tiles tend to arch.
