감열지는 열에 민감한 특수 소재입니다., 그것은 화학 반응 후에 가열될 수 있습니다, so as to produce visible images or words. Thermal paper usually consists of two main parts: a substrate and a thermal layer.

1. Substrate: the substrate of thermal paper is used to support and transfer the thermal layer of the material. Common substrates include paper, 플라스틱 필름, 등. The choice of substrate depends on the application requirements of thermal paper, such as the need for wear resistance, water resistance and other characteristics.

2. Thermal layer: Thermal layer is a key part of thermal paper, which contains heat-sensitive chemicals. The thermal sensitive layer is usually composed of thermal ink or thermal dye. When thermal paper is stimulated by thermal energy, the chemical substances in the thermal layer will change color or react chemically to form images or words.

3. Back adhesive layer: thermal paper is generally attached to some kind of test, so it is necessary to prepare a layer of back adhesive on the back, and the back adhesive is generally specially modulated hot melt adhesive.

How to prepare adhesive for thermal paper?
The preparation of the back adhesive of thermal paper requires certain professional equipment and materials. The following are the basic steps for general adhesive preparation:

재료 준비: Prepare the required raw materials, including rubber powder, solvent, 안정제, 등. Select suitable materials for thermal paper applications and ensure their quality and purity.

Dissolve the rubber powder: add the rubber powder to the appropriate solvent, 물이나 유기용제 등, according to the formula and proportion provided by the manufacturer. According to the characteristics and solubility of rubber powder, select the appropriate solvent.

Mixing and stirring: The dissolved rubber powder and solvent are mixed together and stirred using appropriate mixing equipment to ensure that the rubber powder is completely dissolved and a uniform glue solution is formed.

Addition of stabilizers: As required, stabilizers can be added to the adhesive solution to improve the stability and viscosity of the adhesive solution and ensure its performance during preparation and use.

Filtration and defoaming: The glue is filtered through filtration equipment to remove suspended particles and impurities. 동시에, corresponding measures can be taken, such as vacuum defoaming, to eliminate the bubbles in the glue solution.

Back glue coating: evenly spread the glue on the back of the thermal paper. Use experimental automatic coating machine/roll to roll coating machine (small production) 접착제가 종이 표면에 균일하고 지속적으로 코팅되도록 공정 제어.

건조 및 경화: 코팅된 감열지를 오븐이나 기타 건조 장비에 보내거나 가열형 코팅 기계를 사용하여 긁어 코팅하고 긁어 코팅한 후 동시에 건조할 수 있습니다., 접착제 용액에 있는 용매를 제거하기 위해, 접착제 용액이 경화되어 뒷면 접착층을 형성하도록. 접착제 용액의 특성 및 준비 요구 사항에 따라, 적절한 건조 시간 및 온도 조절.

절단 및 포장: 건조 및 경화된 감열지를 절단, 포장하여 최종 점착 감열지 제품을 얻습니다.. 포장 과정이 위생 요구사항과 제품 품질 보호를 충족하는지 확인하세요..
