What is the ratio of low pressure material and high pressure material, high pressure material and lo

Low-pressure material: low-pressure polyethylene.

A kind of polyethylene (PE) plastic. Polyethylene is the simplest polymer in structure and the most widely used polymer material. It is made up of duplicate CH2 units connected. Polyethylene is formed by the addition polymerization of ethylene (ch2=ch2).

High-pressure material: High-pressure polyethylene (PEF) is a production line with advanced foaming technology, using the most advanced scientific formula, high-pressure polyethylene, flame retardant.

Foaming agent, cross-linking agent.

and other raw materials are blended, and the polyethylene hydrocarbon is foamed through the high rate of chemical bridging through internal refining and smelting, and becomes a product with a network polymer structure and balanced open-cell bubbles.

Low-pressure material: Low-pressure polyethylene refers to polyethylene made at lower pressure, with a density of gram cubic centimeters; It is called high-density polyethylene, and the English abbreviation refers to linear low-density polyethylene, which is similar in density to low-density polyethylene. MPE stands for metallocene polyethylene, that is, polyethylene made with metallocene as a catalyst with a density of gram cubic centimeters.

Both LLDPE and MPE are new types of polyethylene and do not fall under the high-pressure polyethylene range.

High-pressure material: high-pressure polyethylene refers to the polyethylene plastic raw material made by the high-pressure production process, with a density of gram cubic centimeters, called low-density polyethylene, abbreviated as LDPE in English.

First of all, it is divided into high and low pressure, the pure low-pressure bag feels harder, and it will make a noise when rubbed by hand, and the high-pressure bag is softer, and the nature and low-pressure can be said to be the opposite. If you mix recycled material in it, you can divide it according to the smell, the pure material is tasteless, the greater the smell, the more regeneration is mixed, in the direction of the bag to rush to the light, to see if the inside is uniform, the bag of pure material is relatively clear, mixed with regeneration There will be a small point, or there is a snowflake-like thing, you can see it if you look carefully, and then the color, the bag of pure material is transparent, and the transparency of regeneration will be reduced. Haha, there are a lot of things, and you won't be able to tell for a while, and you still need practical experience to distinguish them. Oh.

Summary. Dear, I'm glad to answer for you;

A: Generally, LDPE is blown, and the addition of linear material can reach 80%, or even 90%. Add 10% to 15% to blown HDPE film, in increasing the ratio, the film will become very soft, affecting the feel. Blow the high-pressure bag press 1:

The proportion of linear material added to the ratio of 1 is made into a finished product and sent to Beijing and other cold areas, and the customer responds that the product is not frost-resistant, and is as brittle as glass.

I hope mine can help you, if you are satisfied with my service, please give a thumbs up, I wish you all the best!

The material that distinguishes between high pressure and low pressure in plastics is generally PE material.

High-pressure materials generally have a low density, and our common LDPE, LLDPE, and MLLDPE are all high-pressure materials, with many grades, and their densities are generally scattered or below.

Low-pressure materials generally have a higher density, we generally call it HDPE, and its density is around. Polypropylene (PP) is not differentiated according to high and low pressure, usually said high pressure, low pressure is polyethylene (PE), the difference is that high-pressure polyethylene has a lower density (also known as low-density polyethylene LDPE), while low-pressure polyethylene has a relatively high density (also known as high-density polyethylene and HDPE).

Classification of plastics and classification of uses:

1. Mineral water bottles, carbonated beverage bottles, and beverage bottles should not be recycled with hot water.

2. Cleaning supplies and bath products.

3. Some decorative materials.

4. Cling film, plastic film, etc.

5. Microwave oven lunch box.

6. Bowls of instant noodle boxes and fast food boxes.

7. Kettles, cups, bottles. <>

Summary. High-pressure material: high-pressure polyethylene (PEF) is a production line with advanced foaming technology, using the most advanced scientific formula, blending with high-pressure polyethylene, flame retardant, foaming agent, cross-linking agent and other raw materials, and foaming polyethylene hydrocarbons through chemical bridging through high-rate foaming through internal refining and smelting, and becoming a reticulated polymer structure and balanced open-cell bubble products.

Hello, about your question what do I think is low-pressure material and high-pressure material.

High-pressure material: high-pressure polyethylene (PEF) is a production line with advanced foaming technology, the most advanced scientific formula for closed shooting, blended with high-pressure polyethylene, flame retardant, foaming agent, cross-linking agent and other raw materials, and the polyethylene olefin is foamed through the chemical bridge through high-rate foaming through the chemical bridge after internal refining and refining, and becomes a reticulated polymer bending structure, balanced open-cell bubble product.

Hope it helps.

Summary. Hello <>

The ratio of high-pressure material and low-pressure material needs to be determined according to the specific situation. Generally speaking, high-pressure and low-pressure materials refer to asphalt mixtures with different viscosities, respectively. In road construction, in order to ensure the durability and stability of the pavement, asphalt mixtures with different viscosities need to be mixed in a certain proportion.

Specifically, the following factors need to be considered when determining the ratio:1Environmental conditions:

Different environmental conditions such as temperature and humidity in different regions will also have an impact on the ratio of asphalt mixture. 2.Pavement Grade:

Different grades of pavement require different ratios of asphalt mixtures to meet different load-bearing capacity and service life requirements. 3.Construction method:

Different construction methods will also have an impact on the ratio of asphalt mixture, such as spraying, tiling, etc. 4.Asphalt Quality:

Different varieties of asphalt have different properties and need to be adjusted according to the actual situation. Combining the above factors, the asphalt mixture ratio suitable for the region, the road grade and the construction method can be obtained through test and experience.

The ratio of high-pressure material and low-pressure material needs to be determined according to the specific situation. Generally speaking, high-pressure and low-pressure materials refer to asphalt mixtures with different viscosities, respectively. In road construction, in order to ensure the durability and stability of the pavement, asphalt mixtures with different viscosities need to be mixed in a certain proportion.

Specifically, the following factors need to be considered when determining the ratio:1Environmental conditions:

Different environmental conditions such as temperature and humidity in different regions and branch search will also have an impact on the ratio of asphalt mixture. 2.Pavement Grade:

Different grades of pavement need to use asphalt mixtures with different ratios to meet the requirements of different bearing capacity and life loss. 3.Construction method:

Different construction methods will also have an impact on the ratio of asphalt mixture, such as spraying, tiling, etc. 4.Asphalt Quality:

Different varieties of asphalt have different properties and need to be adjusted according to the actual situation. Combining the above factors, the asphalt mixture ratio suitable for the region, the road grade and the construction method can be obtained through test and experience.

In actual production, the ratio of high-pressure material to low-pressure material is usually 3:7 or 4:6.

The viscosity of these two asphalt mixtures is not the same, the viscosity of the high-pressure material is large, and it has good shear resistance, while the viscosity of the low-pressure material is small, and it has good pavability and mixability. After mixing the two in a certain proportion, their respective advantages can be taken into account, so as to obtain an asphalt mixture with better performance and more suitable for actual needs. At the same time, it is necessary to pay attention to the mixing of the mixture to ensure the stable quality and balanced performance of the mixed asphalt mixture.
