Automatic batching silicone production line

Solution Overview:

Overall layout : The schematic layout is drawn as usual, and then adjusted according to the production site and production process flow ;

Capacity matching: According to the capacity of the previous sealant production process, the number and layout of three-roller milling machine and automatic batching stations are matched;

Process flow : powder raw material + liquid raw material ( manual feeding or automatic batching ) Mixing kettle stirring ( rotor pump or screw pump output )kneader mixing ( rotor pump or screw pump output ) Material moving tank ( manual transfer or automatic transfer) Hydraulic extruder discharge three-roll mill Material moving tank ( manual transfer, static or automatic transfer) Hydraulic extruder discharge ( batch machine PLC program control discharge) Automatic batching Product moving tank ( manual transfer or automatic transfer) Planetary mixer stirring ( manual button control or PLC program control automatic operation) Product moving tank ( manual transfer or automatic transfer) Lifting hydraulic extruder​ Product metering filling ( manual metering or weighing filling automatic filling) Upper cover clamping ( manual ) Product output ( manual or automatic palletizer )

Automatic batching: adopts weighing and metering, and PLC program controls the extruder , centrifugal pump, valve, etc. to batch one Material, five oil materials, two liquid materials, and one color paste according to the weight and order of the set formula , realizing one-key start and automatic batching . After completion , it will alarm or automatically enter the next station;

Material transfer: Mobile tanks are used for material transfer between processes, and manual operation is adopted ;

Silicone sealant production line

ISolution Overview:
Raw material preparation
- Base polymer: 107 silicone rubber, i.e. polydimethylsiloxane, is often used as the main raw material. It is a colorless, transparent, viscous liquid that can give the sealant basic properties. The Si=O chemical bond in its molecular structure has high energy and outstanding UV resistance.
- Crosslinking agents: such as acetic acid type, ketoxime type, alcohol type and amino type, which can make silicone into a solid elastomer. Different types will affect the curing speed and final performance.
- Filler: Generally, active nano calcium carbonate, white carbon black, etc. are used to change the mechanical and rheological properties of the sealant.
- Plasticizer: commonly used silicone oil and silicone resin, can adjust the flexibility and processability of the sealant, improve its fluidity and construction performance.
- Catalysts: mostly organic tin compounds, organic titanium compounds, etc., which can accelerate the curing reaction and promote the rapid curing of the sealant.
- Other additives: Add antioxidants, UV absorbers, colorants, mildew inhibitors, etc. as needed to give the sealant specific properties.
Ingredients
Weigh each raw material precisely in a specific ratio to ensure that each component is evenly dispersed to ensure consistent sealant performance.
Mixing and stirring
Add the raw materials into a high-speed blender and mix thoroughly to form a uniform mixture. Strictly control the temperature and time during the process to prevent overheating of the materials or uneven mixing.
Degassing
The mixed materials need to be vacuum degassed to remove bubbles and volatile substances to ensure product quality and stability.
Package
The degassed silicone sealant is packaged in a dust-free environment. Depending on the application requirements, it is packaged in containers such as hoses, tanks or barrels. The packaging must be well sealed to prevent the ingress of air and moisture.
Storage and transportation
The packaged silicone sealant should be stored in a dry, cool place, away from direct sunlight and high temperature, and prevent collision and extrusion during transportation.
The main production equipment for silicone sealants are as follows:
Base material making equipment
- Powerful Disperser: As a multifunctional mixer, it can finely mix and homogenize silicone rubber, and can also make base materials and glue. There are three stirrers in the kettle, which can make the materials move in a complex manner, subjecting them to strong shearing and kneading.
- Double planetary power mixer: a new type of dead-point mixing equipment, the mixing effect is more refined than the strong disperser, but the cost is higher.
Discharging equipment
The glass glue hydraulic discharging machine is suitable for the hydraulic discharging of high-viscosity materials and the dispensing of 200L iron drums. After being equipped with a dispensing table, it can also be used for the dispensing of plastic tubes and soft packaging.
Filling equipment
Glue filling equipment is divided into three types: manual, semi-automatic, and fully automatic filling, as well as hard tube filling, hose packaging, soft bag packaging, etc., which can realize functions such as automatic detection, diagnosis, and processing of production processes.

AB glue production process equipment

type:     The types of AB glue can be divided according to the raw materials used, which can be divided into acrylic AB glue, epoxy resin AB glue, silicone AB glue, polyurethane AB glue, etc.
Polyurethane AB glue: The main raw material is polyurethane, which is mainly used for potting, coating, etc. Due to its advantages such as adjustable performance and wide application range, it has become a product with many varieties and large output among polyurethane glues.
Customer Case: Two sets of polyurethane sealant production equipment for Ukrainian customers
