Application of nitrocellulose
Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone
Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.
Vietnam has many delicious avocados such as: Sap avocado, 034 avocado, Tu Quy avocado, Booth avocado, Hass avocadoâ?¦. These avocados are suitable for red basalt soils in the Central Highlands and have been exported to many countries.
Avocado is one of the fruits containing many beneficial vitamins for humans. Avocado provides a lot of nutrients as well as fiber for the body.
Avocados are mostly consumed fresh as a salad fruit. However, in Viet Nam avocado mostly used as juice by grinding the flesh and mixing with milk giving a nice taste of a kind of a drink.

TALC ROCK
Talc has the ability to absorb moisture, oils, odor, serve as a lubricant, and produce an astringent effect on human skin. These properties have made talcum powder an important ingredient in many baby powders, foot powders, first aid powders, and a variety of cosmetics.
Uses of Talc
1 Plastics
It is mainly used as a filler. Increase the stiffness of products such as polypropylene, vinyl, polyethylene, nylon, and polyester .It can also increase the heat resistance of these products and reduce shrinkage.
2 Ceramics
In the manufacturing of ceramics products such as bathroom fixtures, ceramic tile, pottery, and dinnerware. Improve the firing characteristics of the green ware and the strength of the finished product.
3 Paint
Talc is used as an extender and filler in paints. The platy shape of talc particles improves the suspension of solids in the can and helps the liquid paint adhere to a wall without sagging.
Talc an excellent filler in paint because it simultaneously serves to whiten and brighten the paint.
4 Paper
Talc as a mineral filler can improve the opacity, brightness, and whiteness of the paper. Talc also can also improve the paper�¯�¿�½?�?�¢??s ability to absorb ink.
5 Cosmetics and Antiperspirants
Talc is used as the powder base of many cosmetic products. The tiny platelets of a talc powder readily adhere to the skin but can be washed off easily.
Talc�¯�¿�½?�?�¢??s softness allows it to be applied and removed without causing skin abrasion.
The ability of talc to absorb moisture, absorb odor, adhere to the skin, serve as a lubricant, and produce an astringent effect in contact with human skin make it an important ingredient in many antiperspirants..
6 Roofing Materials
Talc is added to the asphaltic materials used to make roofing materials to improve their weather resistance. It is also dusted onto the surface of roll roofing and shingles to prevent sticking.
7 Dimension Stone
A rock is known as �¯�¿�½?�?�¢??soapstone�¯�¿�½?�?�¢?? is a massive variety of talc with varying amounts of other minerals such as micas, chlorite, amphiboles, and pyroxenes.
It is a soft rock that is easy to work, and that has caused it to be used in a wide variety of dimension stone and sculpture applications.
8 It is used for countertops, electrical panels, hearthstones, figurines, statuary, and many other projects.
9 Ground talc is used as a lubricant in applications where high temperatures are involved.
10 It is able to survive at temperatures where oil-based lubricants would be destroyed.
11 Talc powder is used as a carrier for insecticides and fungicides.
12 It can easily be blown through a nozzle and readily sticks to the leaves and stems of plants.
13 Its softness reduces wear on application equipment.
CRYSTAL MOUNT CO. FOR MINING & SUPPLYING (limited) provide talc rock in different types with high quality and commitment in delivery.

Pink Himalayan salt is a type of rock salt, or halite, that is known for its distinctive pink color, which comes from trace minerals like iron, magnesium, potassium, and calcium.It is used as a food additive, in cooking, and for decorative purposes like salt lamps. While it's often promoted with claims of health benefits, these claims are largely unsubstantiated.
Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage
SRC is a type of cement where its clinker is blended with specific proportions of gypsum and bypass materials. This combination not only makes it durable against sulfate-induced damage but also provides a strong and reliable construction material.
SRC distinguishes itself by its minimal Tri Calcium Aluminate (C3A) content, a crucial characteristic. C3A is a chemical reaction with sulfate ions found in soil and water, which can lead to concrete expansion and cracking. As sulfate attack progresses, the affected concrete's strength and durability can significantly decrease. Sulfate attack can also manifest as surface scaling and deterioration of the concrete.
The concrete may become discolored, pitted, and crumbly. If sulfate attack continues unabated, it can lead to structural issues, including reduced loadbearing capacity, which can compromise the safety and integrity of the concrete structure. This unique property of SRC plays a vital role in inhibiting such expansion and cracking, strength and durability deterioration, especially in areas where the soil has elevated sulfate levels.
SRC is employed in a wide range of construction endeavors, including the infrastructure in sulphate-rich soils, construction of dams, coastal and marine structures like ports and platforms, sewage and Water treatment plants, repair and rehabilitation, underground Structures, and foundational work.
The rock wool products regard basalt as its main raw materials, after the towering stove is melted, make basalt high-temperature melting body into inorganic fiber with high-speed acentric equipment, put bond, polish, silicone oil in at the mean time. According to different requirements, we can manufacture many kinds of products such as rock wool plate¡¢rock wool tube¡¢rock wool blanket. It is widely used in varies of high-temperature pipe¡¢tank and equipment insulation of the domain of oil¡¢chemical¡¢metal and so on .Also can be used in thermal insulation of boats and the insulation and sound absorption of the buildings wall and ceiling.
