Core parameters and operating guidelines for continuous laboratory hot melt adhesive coater
Introduction
The laboratory hot melt adhesive coater is a key equipment used for glue coating in the laboratory environment, and its efficient and accurate coating function plays an important role in scientific research, testing and small batch production. This paper will deeply discuss the core technical parameters and operation methods of continuous laboratory hot melt adhesive coater, in order to help users better understand and give full play to the performance of this equipment.
First, core technical parameters
1.1 Coating speed
Coating speed is one of the key parameters to measure the performance of hot melt adhesive coater. Usually in meters/minute, the choice of coating speed should be determined according to the experimental needs and the characteristics of the glue. The higher coating speed can improve the experimental efficiency, but also take into account the coating uniformity and the curing time of the glue.
1.2 Coating width
Coating width refers to the maximum width range of a coating, in millimeters. The choice of coating width should be determined according to the size of the experimental sample to ensure that the coating covers the entire surface of the sample.
1.3 Temperature control range
The coating effect of hot melt adhesive is greatly affected by temperature, so temperature control is one of the important technologies of laboratory hot melt adhesive coating machine. The temperature control range should be wide enough to adapt to the coating needs of different types of glue.
1.4 Pressure Regulation
The glue pressure during coating is one of the key factors affecting the uniformity of coating. The hot melt adhesive coater should have a pressure adjustment function to meet the coating requirements of different glues and materials.
1.5 Cooling System
After coating, the glue needs to be cooled quickly and evenly to ensure the stability and adhesion of the coating layer. The design and performance of the cooling system are crucial to the experimental results.
1.6 Control System
The reliable control system can provide more operation options and the function of recording experimental data. Users can control the coater accurately through the control system, and monitor the parameters in real time, so as to better grasp the experiment process.
Second, operation method
2.1 Preparations
Before the experiment, the laboratory hot melt adhesive coater needs to be fully prepared. This includes checking whether the equipment is working properly, whether the glue and sample preparation is adequate, etc.
2.2 Parameter Settings
According to the experimental requirements, parameters such as coating speed, coating width, temperature and pressure are set. Ensure that the Settings of these parameters can meet the requirements of the experiment and avoid the failure of the experiment due to improper parameter Settings.
2.3 Sample Preparation
Prepare the sample that needs to be coated to ensure that the surface of the sample is clean, flat, and meets the dimensions required for the experiment. Note that the surface treatment of the sample may affect the coating effect, and pretreatment should be performed according to the experimental requirements.
2.4 Glue coating
Start the hot melt adhesive coating machine and start the experiment. Pay attention to monitoring the parameters of the coating process to ensure uniform and stable coating. Select suitable coating mode according to experimental requirements, such as single-side coating, double-side coating, etc.
2.5 Cooling and curing
After finishing the coating, ensure that the coating layer is sufficiently cooled and cured. This usually takes a certain amount of time, according to the nature of the glue and experimental requirements to determine.
2.6 Data recording and analysis
The control system of the hot melt adhesive coating machine was used to record the parameters during the experiment, so as to analyze the data and evaluate the experimental results. This helps to optimize the experimental process and improve the experimental design.
2.7 Cleaning and Maintenance
After the end of the experiment, the various parts of the coater should be cleaned in time to ensure that the equipment is in good working condition. Perform regular maintenance to check the wear and performance of key components such as coating rollers, heating elements, and pressure sensors.
