ldpe granules petrochemicals suppliers in Tehran

Lightweight polyethylene (ldpe granules petrochemicals ) is commonly used in the production of various types of plastic materials. Polyethylenes of 209 and 020 are from this category of materials. That produce nylon-niloxes-the production of small-sized polyethylene pipes-the production of a type bar for drip irrigation-the production of various types of polyethylene and more. used.
Polyethylenes

A family of thermoplastics obtain by polymerization of ethylene gas (C2H4). Low molecular weight polymers use as lubricants. The polymers of the average molecular weight of the waxes fuse with paraffin. And also finally, polymers with a molecular weight greater than 6000 in the plastic industry account for the largest volume of consumption. Polyethylene contains a very simple structure, which is simpler than all commercial polymers.

Light polyethylene

Sometimes instead of hydrogen atoms in the molecule (PE). A long chain of ethylene to carbon atoms attache to them, polyethylene branch or low-density polyethylene (LDPE) say. Because its density due to occupy more volume, was reduced. In this type of polyethylene, the molecules of ethylene also are randomly attached to each other and poured into a very irregular shape.
Lightweight polyethylene (low density) is generally a softer polythene and has a lower crystallinity. This polymer usually present as globulin and is widely used in applications where transparency, neutrality, ease of processability, durability and good electrical properties are considered.

Polyethylene Style 209

The grade of this product is about 0.9 and the packaging is 209 polyethylene bags in 25kg bags.
Light polyethylene
020 is also a subsidiary of the production of various types of nylon-made nylon-made plastic nylon containers and extra. The polyethylene is lightweight 020 and the degree of rhinestone of this product is about 2.3 and its packing is in 25 kg bags.
Polythene also is a film of polymer material in the group of thermoplastics. It uses for producing polyethylene pipes, making small containers, making household dishes, toys, wrapping electrical and telecommunication cables, films, various parts of cars, appliances Sports and labs and industrial parts.

Polyethylene film style ldpe granules petrochemicals

Polyethylene low density (ldpe granules petrochemicals ) also is a polymer material and in the group of thermoplastics. Film style polyethylene has a branched chain.
LDPE chains can not bond well, with less intermolecular force and tensile strength.
It use to produce polyethylene pipes, to make small volume containers. To make household utensils, toys, electrical and telecommunication cables, films, various car parts, sports equipment and labs, and industrial parts.

Film style polyethylene also is usually stable, it needs to preheat for fire, almost no protection.
This polyethylene has branched chains, so LDPE chains can not bond well, with less intermolecular force and tensile strength. This type of polyethylene usually produce by radical polymerization.

The properties of this polymer are flexible and decompos by microorganisms. Polyethylene in terms of compactness, low and low-molecular low density is the same, increase its flexibility. This property makes more than fifty percent of production in film and sheet for use in coatings talcous transparent, Inserts closed Covers, covers and luggage. This kind of polymer also use to make plates like pressure bottles.
Other uses include lightweight polyethylene, insulating wires and cables, and paper overlays. Polyethylene was first synthesized accidentally by a German chemist.

sulphur granule

Sell sulfur granules and direct effects on soil

Sulfur granules is an essential element for plant nutrition and its role is superior to phosphorus. Also the role of sulfur in plants, mainly the production of protein, oil and improve the quality of agricultural products. The fourth essential element for nitrogen plants is phosphorus and sulfur potassium. With the difference that plants need this element even more than phosphorus.

Sulfur granules benefits in agricultural soils

The results of the experiments have shown that if sulfur is incorporated with organic matter and thiobacillus bacteria with the correct method and the moisture content is optimal, it can increase up to 60% of the yield of agricultural products. The form of sulfur used by plants is ion sulfate. Therefore, oxidation conditions in the soil should be provided to convert sulfur to sulfate.

To use sulfur, it is necessary to prepare four conditions (moisture, organic matter, deep deposition, and sulfur oxidizing microorganisms) by converting it to sulfate.

Studies also have shown that irrigation water bicarbonate reduces yield. When sulfur is added to the soil, oxidizing bacteria oxidize sulfur to sulfate. This process produces acid and ultimately produces sulfuric acid, and the sulfuric acid proton causes acidification of the soil. The amount of sulfur and its conversion rate to sulfuric acid depends on the amount of moisture, population, and oxidative power of microorganisms in the soil and temperature. The speed of this reaction is slow. Sulfur is an element that requires at least two years to completely convert to sulfuric acid. In this reaction, the solubility of iron, zinc and manganese increases and the yellowish content decreases.

Another role of sulfur granules  is to use it to modify salt and alkaline soils. Types of sulfur entering the soil include the use of various fertilizers containing sulfur (enriched fertilizer), sulfur minerals, the use of sulfur-containing modifiers, the addition of organic residues to the soil, and the introduction of sulfur through the atmosphere, pesticides and irrigation water. Sources of sulfur removal from the soil include sulfur uptake by plants and microorganisms, leaching, soil erosion, burning of plant remains and sulfur sublimation from soil.

The role of sulfur in soil and agriculture

The fourth essential element for nitrogen plants is phosphorus and sulfur potassium. With the difference that plants need this element even more than phosphorus. Sulfur is deliberately “involved in the production of amino acids and proteins. And its shortage reduces the product’s quantitative and qualitative performance. On the other hand, the lack of organic matter and the bicarbonate of most irrigation water limits the solubility of high-energy nutrients and micronutrients. And practically, the absorption of these elements is slow. So, the nutrition of sulfur in plants and their consumption is very important.

Sulfur Granules

Benefits of Sulfur Use in Crops and Gardens

  • Increasing the solubility of nutrients especially phosphorus, iron, zinc, manganese and, on the other hand, reduction in phosphate and micronutrient fertilizers
  • Improving the quality of irrigation water
  •  Fulfilling the required sulfur content of the plant and increasing yield per unit area
  •  Correction of PH salts and alkali and calcareous soils
  •  Reduced nitrate accumulation in agricultural products
  •  Avoid the spread of soil fungi in terms of the fungicidal properties of sulfur
  •  Gradual soil sterilization and contributing to environmental health and reducing agricultural use.

Symptoms of sulfur deficiency in plants

In plants, sulfur deficiency appears as pale and jaundice in young leaves and the plant’s lateral parts. Sulfur deficiency also has important effects on plant growth, stems are thin and leaves are complicated. In plants, sulfur deficiency causes the accumulation of non-protein nitrogen, and the use of these plants is harmful and harmful to ruminants. Sulfur deficiency also causes nitrate accumulation in plants that are toxic to animals.
Sulfur is an essential element for plant nutrition and its role is superior to phosphorus. The role of sulfur in plants, mainly the production of protein, oil and improve the quality of agricultural products

epdm granules in iran

epdm granules suppliers in iran

Iran is one of the big names in rubber granules and flooring, which is used for various uses. Rubber granules are new to the epdm material in their structure.
The rubber granules are mesh and are used in sizes of 3-5 in the artificial turf manufacturing structure. The good selling price of artificial grass granules in high volume is extremely affordable. One of the oil products that is produced annually in Iran in a light and heavy-duty type is the tires of riding and truck tires. But are these tires the fate of what’s going on after wearing out? … These worn tires have environmental damages, and while they also make the face of nature unnatural, and so are the solutions that entrepreneurs have today Which will turn to the recycling industry and produce rubber granules . A granule that can throw the cycle of artificial grass products in our country.
