The accuracy amount of compounding when making silicone dipping process

When the rope head is dipped in silicone, the accuracy of the amount of compounding agent can be ensured. The following aspects can be taken into consideration:
Precise formula design and recording:
Scientific design of formula: Before production begins, professional technicians will scientifically and rationally design the formula of compounding agents based on the performance requirements of silicone and the use scenarios of the rope head. Consider various factors such as the hardness, elasticity, and temperature resistance of silicone to determine the types and proportions of various compounding agents.
Detailed record of formula: Record the determined formula in detail, including the name, specifications, and dosage of each compounding agent. Establish a special formula database to facilitate access and verification during the production process to ensure the accuracy and consistency of the formula.
Accurate measuring tools and operations:
Select high-precision measuring equipment: Use high-precision electronic scales, measuring cylinders and other measuring tools to ensure that the amount of compounding agents can be accurately measured. Regularly calibrate and maintain measuring tools to ensure their precision and accuracy. For compounding agents with smaller dosages, more accurate measuring tools such as microbalances or syringes can be used.
Standardize the measurement operation process: Establish a strict measurement operation process and require operators to measure according to the prescribed steps. When weighing the compounding agent, pay attention to the correct reading method to avoid inaccurate dosage due to reading errors. At the same time, ensure that the measuring tools are clean and dry to prevent impurities or moisture from affecting the dosage of the compounding agent.
Strict raw material management and inspection:
Standardize raw material procurement and acceptance: Purchase compounding agents from reliable suppliers and require suppliers to provide quality certification documents and test reports for raw materials. Before the raw materials are put into storage, each batch of compounding agents is strictly inspected to ensure that their quality meets the requirements. Raw materials that do not meet the quality standards will not be used.
Reasonable storage of raw materials: According to the properties and characteristics of the compounding agent, adopt appropriate storage methods. For compounding agents that are susceptible to moisture and volatility, they should be sealed and placed in a dry and cool place. Regularly check the storage of raw materials to prevent the raw materials from deteriorating or failing.
Effective process monitoring and review:
Real-time monitoring of the production process: During the production process of rope head dip-coated silicone, monitoring equipment is installed to monitor the addition process of the compounding agent in real time. Through sensors and control systems, ensure that the compounding agent is accurately added to the silicone according to the set ratio. If abnormal conditions are found, make adjustments and handle them in time.
Regularly review the dosage: Regularly review the dosage of the compounding agent used in the production process, compare it with the formula, and check whether there is any deviation. The used compounding agents can be counted and analyzed by weighing, measuring and other methods. If the dosage is found to be inaccurate, find the cause in time and take corresponding corrective measures.
Employee training and quality awareness improvement:
Strengthen employee training: Provide professional training for operators to familiarize them with the properties, measurement methods and operation procedures of compounding agents. The training content includes the use of measuring tools, the execution of formulas, quality control and other aspects. Through training, improve employees' operating skills and quality awareness to ensure that they can accurately add compounding agents.
Establish a quality assessment mechanism: Establish a quality assessment mechanism to evaluate and assess the operating quality of employees. Include the accuracy of the dosage of compounding agents in the assessment indicators, reward employees with outstanding performance, and punish employees with quality problems. In this way, employees are encouraged to pay attention to the accuracy of the dosage of compounding agents and improve product quality.
What are the main ingredients of silicone diluent?
The main components of silicone diluents vary depending on the type and purpose. The following are the main components of some common silicone diluents:
Organic solvents:
Toluene, xylene: They are common aromatic organic solvents that have a certain ability to dissolve and dilute silicone. Toluene is a colorless, clear liquid with a benzene-like odor; xylene is the product of two hydrogens on the benzene ring being replaced by methyl groups. There are three isomers, o-, m-, and p-. In industry, xylene refers to a mixture of these three isomers. In some silica gel dilutions, they can effectively reduce the viscosity of silica gel, making it easier to construct and operate, but such organic solvents have certain toxicity and volatility, so safety and ventilation should be paid attention to when using them.
Cyclohexane: It is an organic compound, a colorless liquid with a pungent odor. It is insoluble in water and easily soluble in organic solvents such as ethanol and ether. It can be used as a diluent for silica gel. Its molecular structure is relatively stable. It can maintain good chemical stability during the dilution of silica gel, which helps to evenly disperse silica gel, but it also has certain volatility.
Silicone oil:
Methyl silicone oil: This is the most commonly used type of silicone oil, with the chemical name polydimethylsiloxane. It is a colorless and transparent oily liquid with good chemical stability, electrical insulation and high and low temperature resistance. In the dilution of silicone, methyl silicone oil can not only reduce the viscosity of silicone, but also improve the flexibility and demolding properties of silicone to a certain extent. In addition, its volatility is low, and the harm to the environment and human body is relatively small. It is a relatively safe silicone dilution component.
Phenyl silicone oil: A type of polysiloxane with a silicon-oxygen bond as the main chain and a phenyl group introduced on the silicon atom. In addition to the characteristics of general silicone oil, it also has higher temperature resistance and radiation resistance. When used for silicone dilution, it can give silicone better high temperature resistance and radiation resistance, and is suitable for the dilution of some special silicone products with high environmental requirements.
Hydrogen-containing silicone oil: Polysiloxane containing silicon-hydrogen bonds (Si-H) in the molecular structure. Under certain conditions, the silicon-hydrogen bonds in hydrogen-containing silicone oil can react with other substances containing active groups (such as double bonds) to play a role in crosslinking or modification. During the dilution of silicone, it can not only reduce the viscosity of silicone, but also participate in the vulcanization reaction of silicone, affecting the degree of cross-linking and final performance of silicone, such as improving the hardness and strength of silicone.
