    What are the main uses of Antimony Trioxide Masterbatch?
    Antimony white masterbatch is also a industrial compound. Its quality is white and stable, and it is mostly integrated with polymers. Talking about its uses today, it is roughly as follows: First, antimony white masterbatch is an excellent flame retardant. All plastic utensils, if they are not flame retardant, are flammable in case of fire, which is harmful to people's livelihood. Antimony white masterbatch is mixed with polymer materials, which can improve its flame retardant level and protect the safety of utensils. Therefore, it is widely used in polyethylene, polypropylene, polyvinyl chloride and other resins. It is especially important for wires and cables, building decoration, and automobile parts. The finished products are assisted by antimony white masterbatch, which can resist flames and stop disasters before they burn.
    Second, antimony white masterbatch is both dispersed. The main properties of antimony white powder are not easy to distribute evenly in the resin. If it is a masterbatch, it is fine and easy to mix, and the finished product is smooth. The antimony white in the masterbatch is embedded in a polymer carrier, which can effectively prevent the agglomeration and loss of antimony white, so that the color scheme is stable, the performance is the same, and the production is convenient. Its benefits are found in films, pipe fittings, and plates.
    Third, the performance of antimony white masterbatch auxiliary materials is improved. Household electronics, communication equipment, and lamp shells should not be neglected except for stability and insulation. Antimony white masterbatch helps flame retardant, and the rest of the properties are also sublimated, which helps to stabilize for a long time. Such as fibers, non-woven fabrics, and engineering plastics can all benefit.
    Fourth, antimony white masterbatch is helpful in environmental protection. In the past, the material was mostly filled with powdered antimony white, which caused excessive dust, and workers were vulnerable to lead damage. Today's masterbatch is formed, which effectively covers dust, makes the production environment light and clean, seeks the health of workers, and reduces the environmental burden.
    Overall, antimony white masterbatch is mainly flame retardant, complementary color and performance, and takes into account environmental protection and technology. Today's plastic products have a wide range of categories, and antimony white masterbatch is irreplaceable. It is actually the most relied on by the modern polymer industry. Such uses are found in the needs of the industry, and are used by the people.
    What is the addition ratio of Antimony Trioxide Masterbatch?
    Antimonte trioxide masterbatch is used to impart flame retardancy to plastics. Those who want to know how to use it must first check the requirements of the product, the content of the masterbatch and the type of plastic. Gaiantimonte trioxide is mostly shared with brominated flame retardants and can be used in various resins such as polyvinyl chloride, polypropylene, polyethylene, ABS, etc. However, the proportion of addition must vary according to different products and performance requirements, and it cannot be determined uniformly.
    In today's prevailing system, the content of antimonte trioxide in the masterbatch is mostly 40% to 70%, which is convenient for transportation and storage and easy to use. If the most commonly used content of 50% is taken as an example, the amount of flame retardant added to the finished product is usually between 3% and 10% of the total resin mass. Then the actual addition ratio of the masterbatch, such as 3% of antimonte trioxide, the masterbatch is based on the content of 50%, and the dosage is 6%. Occasionally, if there are extremely high flame retardant requirements, the addition can also reach 10%. However, if it is used as an auxiliary flame retardant, it can also be reduced.
    As for the operation, it is advisable to add antimonte trioxide masterbatch and brominated flame retardant to the plastic together. After mixing well, it is formed by extrusion, injection molding and other processes. Mixing evenly cannot be ignored to avoid different effects. The diameter of the master particle should be fine, and it is easy to mix evenly in order to give full play to the flame retardant effect. And in engineering practice, it is still necessary to make small trial adjustments in the early stage depending on the compatibility of the master particle and the main material, the processing temperature and even the use of the product. Or increase or decrease, in order to take into account the flame retardancy, processing convenience and cost.
    In general, the correct proportion of adding antimonte trioxide masterbatch is usually between 3% and 10%. It is difficult to achieve the flame retardant effect at least, and it increases the cost and may affect the performance of the product. However, based on the needs of the actual product, it should not be limited to a fixed number. Field tests are required to obtain the best amount of addition. In this way, it can not only ensure the safety of the product, but also facilitate long-term application.
    How is the dispersion and compatibility of Antimony Trioxide Masterbatch?
    Antimony white (ie antimony trioxide) masterbatch is a commonly used flame retardant auxiliary in the field of polymer material processing. To discuss its dispersion and compatibility, its preparation process should be known first. Antimony white is a fine powder with a small diameter and easy agglomeration. If it is incorporated into the polymer matrix alone, it often causes uneven distribution and affects the performance. Therefore, antimony white is melted and embedded in a polymer carrier, and the masterbatch is prepared by multiple shearing and mixing. This method can effectively reduce agglomeration and enhance dispersion. The size of the masterbatch is constant and uniform, which is convenient for storage, transportation and dosing. During hot melt mixing, antimony white is easy to penetrate into the resin system uniformly with the carrier. In this way, the distribution of antimony white particles is fine and the size is stable, which can greatly improve the uniformity and appearance of flame retardant materials.
    In terms of compatibility, the cover depends on the affinity of the selected carrier and the target matrix. If the polymer carrier is similar to the resin polarity, it is easy to melt and mix with each other, and there is no harm of interface delamination. Common polypropylene and polyethylene are used as carriers, which are suitable for the corresponding polyolefin system. If used for polar polymers, such as polyester and nylon, a suitable polar carrier must be selected, or a compatible agent must be applied to reconcile the interface. If the compatibility is good, antimony white is not easy to precipitate, the mechanical properties will not be damaged, and the flame retardancy will be more effective.
    If the dispersion is poor and the particles are agglomerated, the mechanical properties of the material will be weakened, and the appearance will be white and brittle; if the compatibility is weak, the interface will peel off, which is easy to form micro Today's high-end antimony white masterbatch is often supplemented by dispersants and surface coatings to enhance the uniformity and stability of its distribution in the matrix, and to facilitate subsequent processing and molding.
    In summary, the dispersion of antimony trioxide masterbatch is significantly improved compared with the original powder, and it can be uniformly integrated into the polymer material; its compatibility depends on the matching of the carrier and the matrix. If the two are suitable, the flame retardant and mechanical properties are good. Good application is a good way to improve the properties of flame retardant materials, improve processing convenience and product quality.
    How does Antimony Trioxide Masterbatch affect the flame retardancy of the product?
    Antimony white is antimony trioxide, which is often used in the flame retardant of polymer materials. It is made into a masterbatch together with plastics, which is convenient for dispersion and processing. Examining its flame retardant properties in products, there are several great benefits.
    One, antimony trioxide has no flame retardancy, but it can cooperate with halogen flame retardants. Together with fire, halogens are heated to produce hydrogen halides, and antimony reacts to them, forming antimony trioxide and antimony halogens, causing dense glass bodies on the surface of the material, isolating air and blocking oxidation. The mechanism can slow down combustion and reduce the rate of thermal release. And antimony white can capture free radicals, interfere with chain reactions, and suppress flames.
    Both, the use of masterbatch is especially better than pure powder. The original antimony trioxide is fine and uneven, and the distribution is not good. It is difficult to be compatible with polymers, and it is easy to cause product performance fluctuations. By masterbatch granulation, it can be evenly dispersed in the resin, improve the utilization rate of flame retardants, inhibit sedimentation and agglomeration, and will not affect the product's gloss and machinery.
    Of the three, antimony white is used in an appropriate amount, which can reach an excellent flame retardant level. However, it is an auxiliary, and it must be shared with the main halogen flame retardant agent. The ratio is weighed, and the flame retardant and mechanics are both beneficial. If there is too much antimony white, it may cause material embrittlement, color variation, and damage environmental protection. It If it is used in combination with halogen-free flame retardants such as phosphorus and nitrogen, the effect is weak, and its synergistic characteristics are heavier than those of halogen-containing systems.
    Four, after the addition of antimony white masterbatch, it does not affect the process, and injection molding, extrusion, blow molding, etc. can be applied. The product has stable performance, and the flame retardant grade can generally reach UL94 V0, V1, etc. It is suitable for home appliances, electronics, and building materials. It is commonly used.
    In summary, antimony trioxide masterbatch can enhance the flame retardant effect of products, especially good at halogen-containing flame retardant systems. Its mechanism lies in synergy, which benefits dispersion, which not only guarantees material performance, but also enhances flame retardancy. However, the application needs to be weighed against the ratio, taking into account environmental protection and safety. This is also a good aid for improving the flame retardant performance of products.
    What are the precautions for storage and transportation of Antimony Trioxide Masterbatch?
    The antimony white masterbatch is a chemical substance, and its sexual safety is dangerous. All laws and regulations should be followed for storage and transportation. The texture of the antimony white masterbatch is delicate, and it is easy to be attacked by moisture. If it comes into contact with the air for a long time, there may be a risk of moisture absorption and agglomeration. In the way of storage, choose a place with high ventilation and dryness, away from open flame heat sources, and avoid sun and rain. It should be stored in the original sealed bag, tightly closed, and do not allow air leakage to prevent moisture absorption and deterioration. If it is damaged, it should be replaced in time. In case of humid climate, moisture-proof facilities should be added. The storage warehouse should be neat and clean, and it is forbidden to accumulate flammable sundries to avoid changes.
    When transporting, dry and dust-proof transportation equipment should be used, and corrosive and flammable materials should not be shared with the car. Be properly reinforced on the way, beware of falling and colliding, and prevent damage to the packaging. Be careful when unloading and handling, handle it with care, and do not throw it, so as not to damage the outer packaging and expose it to the air. For long-distance transportation, rain should be isolated from splashing, sun exposure should be strictly protected, and the carriage should be ventilated and dry. In special climates, a tarpaulin should be covered to prevent wind and rain.
    Operators should wear protective gear such as masks and gloves to prevent antimony powder from inhaling and contacting the skin. If it is occasionally scattered, it must be wiped with a damp cloth in time to prevent the spread of dust, and put it into a special container for storage. Warning signs such as "fire and moisture protection" should be hung in the place of storage and handling, and non-relevant responsibilities should not be allowed to enter at will.
    In short, antimony white masterbatch needs to be moisture-proof, dust-proof, and fire-proof, and properly stored and transported; if it is well-kept, it will be safe and secure, otherwise it will be a disaster if it is sparse. To ensure the same quality, first and foremost, be careful with the details, and always be patient.
