Classification of sealing materials, introduction to the classification of building sealing material

Sealing tape triple plate is also a good sealing material.

Sealing materials are widely used in construction. Sealing materials are required for filling gaps in buildings, sealing at the junction of doors and windows, waterproofing kitchens and bathrooms, and leak-proofing roofs. So, what are the building sealing materials that are often used vertically?

What is their performance and market price? Below, I will introduce it to you by category.

There are many kinds of sealing materials, and the sealing materials used in construction can be divided into two categories according to their properties: one is sealing paste. One is the sealing strip.

One is building sealing paste. The building sealing materials of sealing paste are characterized by good fluidity, plasticity and elasticity, and are mainly used to fill building gaps. Most of the building sealants on the market are sealed materials synthesized from polymer materials, and sealants with different compositions have different characteristics.

First, let's look at acrylic sealant paste. The main ingredient of this sealing paste is acrylic density, which has the characteristics of good plasticity, long curing time, high temperature resistance after curing, low temperature resistance after curing, strong fixing force, etc., and is mostly used for filling and sealing the gaps between metals and glass. It has a market price of:

470 grams of acrylic sealing paste** is about yuan.

Next, let's look at polyurethane building sealant. This kind of sealing paste has good plasticity and is mainly used in construction for the sealing of filling at concrete joints. It has the characteristics of wear resistance, high temperature resistance, low temperature resistance, corrosion resistance, etc.

However, this sealing material has poor waterproof properties, so it is generally used to fill gaps in the road surface. Its market price is: more than 11 yuan per kilogram of polyurethane building sealant**.

Again, let's look at polysulfide sealants. This sealing paste has a good anti-aging effect and has a long service life. Because of its corrosion resistance, chemical resistance, and fuel resistance, it is often used for sealing exterior buildings.

Its market price is: about 12 yuan per kilogram of polysulfide sealing paste**.

Finally, let's look at silicone sealing paste. This kind of sealing paste has strong anti-corrosion effect and high temperature resistance and low temperature resistance after curing, and it is not easy to burn. It is generally used for filling joints in places where the temperature varies greatly.

Its market price is: 300ml silicone sealing paste ** is about 75 yuan.

The second is the building seal. The sealing strips generally used in construction are generally rubber products. Rubber sealing strips are widely used in construction, mostly used to fill indoor gaps, because of their good elasticity, so they are mostly used for waterproof, windproof, fixing, etc.

If the rubber sealing strip is used for sealing the edge of the interior door and window, it has a good sound insulation effect. The market price of rubber sealing strips is about 30 yuan per kilogram.

In general, according to the state of building sealing materials, they are divided into two categories: solid and liquid, and each sealing material has different advantages and lack of friends. When selecting building sealing materials, we need to analyze the use environment of the sealing materials, and then select the appropriate materials according to the performance of the sealing materials.

Summary. 2.Anti-friction and anti-wear materials include carbon materials, bearing alloys, cemented carbides, surfacing alloys, engineering ceramics, spraying materials, etc.

It has good heat resistance, cold resistance and high thermal conductivity, and is a friction pair material for the manufacture of dynamic sealing devices such as mechanical seals, piston rings and gap seals.

3.Metallic and non-metallic materials include non-ferrous metals, ferrous metals, cemented carbide, etc., which are used to manufacture other parts in sealing products except friction pairs.

4.Grease & Solid Lubricants Impregnating agents and additives for sealing lubrication systems and as soft fillers. See the table below for details.

It is divided into non-contact sealing and contact sealing.

The main flush of non-contact seals is a variety of mechanical seals, such as: wax graphite packing rings, floating ring seals, etc.;

Rubber-plastic composite seals and rubber-plastic composite seals are all contact seals, which rely on the pre-pressure and tightness of the cavity filled in the sealing cavity to block the leakage channel and obtain the sealing effect.

Most of the seals used in hydraulic systems are static seals, reciprocating seals and rotary seals.

1. Classification according to material dismantling: divided into rubber, engineering plastics, polyurethane, etc.;

2. Classification according to function: guide ring, dustproof seal, rotary seal, divided into shaft seal, fixed seal, hole seal;

Commonly used seal names: sealing ring, packing, mechanical seal Qi Pei, oil seal Luzina, water seal, packing, gasket plate, sealant, soft packing, etc.
