Let s talk about the scope of gypsum applications? Tell me about it?

Plaster is generally used in the medical field in people with broken bones. It is used to immobilize injured bones so that the body can recover quickly.

Plaster can be used in many ways, such as when painting, for example, when it is injured and fixed on the foot.

Gypsum building materials, plastering plaster,

Gypsum can clear the internal fire, the king medicine of white tiger soup.

Gypsum can be divided into medical, mold and building applications, especially in architectural applications: paper-faced gypsum board, paperless gypsum board, gypsum slats, blocks, gypsum heavy and light plastering mortar, masonry mortar, self-leveling gypsum mortar, gypsum wall spraying, pouring slurry, gypsum molding, gypsum fireproof coating and so on.

Sometimes there is a fracture, and then you need to use a cast to fix it, and then it will be very good.

I think plaster can be used in medical treatment, because many people can wear a cast if they have a broken leg or arm.

If our leg or arm is injured, we can use a cast to fix it faster.

Gypsum still has a lot of applications, for example, in the sketch of gypsum, to some home decoration gypsum ceiling board gypsum lines are very wide.

Plaster cast is generally used in medicine, such as dislocated hands and feet, to immobilize hands and feet.

There are many applications of gypsum, such as gypsum board, gypsum modules, etc., which are some good uses of gypsum, and it is recommended to promote.

Advantages: fast coagulation and hardening, and the building gypsum can be completely hardened in about 1 week after mixing with water.

The volume expands slightly when solidifying, which makes the surface of gypsum products smooth, accurate in size, full in shape, good in decoration, and does not produce shrinkage cracks when drying.

The porosity is large, due to the characteristics of the porous structure of the hardened body, so that the building gypsum products have the advantages of small apparent density, light weight, good thermal insulation performance and strong sound absorption, and also have a certain temperature and humidity regulation.

Good fire resistance, after the gypsum dihydrate of building gypsum products encounters fire, the crystalline water evaporates to form a steam curtain, which can prevent the spread of fire and play a role in fire prevention.

Deficiencies: poor water resistance and frost resistance, building gypsum is an air-hard cementitious material, strong water absorption, long-term in a humid environment, the binding force between its crystal particles will be weakened until dissolved, so it is not water-resistant, not frost-resistant.

Poor fire resistance, when the building gypsum is used in the high temperature part of more than 65 for a long time, the gypsum dihydrate is slowly dehydrated and decomposed, and the strength is reduced, so it is not fire-resistant.

Application of Architectural Plaster:

There are many types of building gypsum products, and the main types of gypsum blocks, paper gypsum boards, hollow gypsum strips, fiber gypsum boards, decorative gypsum products, etc.

1) Gypsum board on paper.

There are three types of gypsum board: ordinary gypsum board, water-resistant gypsum board and refractory gypsum board. Ordinary paper-faced gypsum board can be used as an indoor ceiling and interior partition wall, which can be nailed to metal, wood or gypsum keel, or directly pasted on a brick wall. Water-resistant gypsum board is mainly used in wet occasions such as kitchens and bathrooms.

Refractory gypsum board is suitable for interior partition walls, suspended ceilings and decorative boards with high fire resistance requirements.

2) Gypsum hollow slats.

The production method of gypsum hollow slats is similar to that of ordinary concrete hollow slabs. Fibrous materials or lightweight fillers are often added in production to improve the flexural strength of the board and reduce its weight. This kind of board is mostly used in the partition wall of civil housing.

3) Fiber gypsum board.

Fiber materials such as fiberglass, paper tendons or mineral wool are mixed with construction gypsum to make paperless fibrous gypsum board, which has higher flexural strength and elastic modulus than paper gypsum board. Fibre gypsum board is mainly used as interior partition walls, suspended ceilings and prefabricated gypsumboard composite wall panels for buildings.

Gypsum condenses and hardens quickly, the volume expands slightly when hardening, and can be made of exquisite gypsum carving, and the internal void ratio is large, which can be used as hygroscopic items and sound-absorbing items, gypsum is fireproof, but gypsum has poor water resistance, and moisture-proof should be avoided.
