　　Is butyl rubber extruded at an appropriate temperature without sticking to the substrate? The application guide of butyl rubber coating machine is here

　　在中空玻璃生产过程中，丁基胶涂布机是保障密封性能的关键设备。不少行业朋友都会遇到一个棘手问题：明明丁基胶的挤出温度调得适宜，可涂到铝条等基材上后就是不粘，不仅影响生产效率，还会降低中空玻璃的密封效果和使用寿命。其实，丁基胶挤出温度适宜却不粘基材，核心原因并非温度问题，而是基材清洁度、胶种匹配度、涂布工艺等环节出了纰漏。今天就结合丁基胶涂布机的应用，给大家科普问题成因和实用解决方案，中空玻璃行业的朋友赶紧收藏好。

　　In the production process of insulating glass, the butyl rubber coating machine is a key equipment to ensure sealing performance. Many industry friends will encounter a tricky problem: even if the extrusion temperature of butyl rubber is adjusted appropriately, it will not stick when applied to substrates such as aluminum strips, which not only affects production efficiency but also reduces the sealing effect and service life of insulating glass. In fact, the reason why butyl rubber extrusion temperature is suitable but does not stick to the substrate is not due to temperature issues, but rather due to errors in the cleanliness of the substrate, the matching of the adhesive type, and the coating process. Today, combined with the application of butyl rubber coating machine, we will explain the causes of problems and practical solutions to everyone. Friends in the insulating glass industry should collect them quickly.

　　先搞清楚核心问题：为啥温度适宜还不粘？很多人会误以为丁基胶粘接效果只和温度相关，其实不然。在挤出温度达标的前提下，最常见的原因是基材表面不洁净——铝条等基材表面附着的油污、氧化层、灰尘，会在胶层和基材之间形成隔离层，哪怕丁基胶温度适宜、流动性好，也无法和基材充分贴合。其次是丁基胶型号选错，不同环境、不同要求的中空玻璃，需要匹配对应的丁基胶型号，若胶种与场景不适配，哪怕涂布机参数调得再准，也难保证粘接效果。另外，涂布机的涂胶厚度、均匀度控制不当，或是操作环境潮湿，也会导致看似温度适宜却不粘基材的情况。

　　First, clarify the core question: why is the temperature suitable but not sticky? Many people mistakenly believe that the bonding effect of butyl rubber is only related to temperature, but this is not the case. Under the premise of reaching the extrusion temperature standard, the most common reason is that the surface of the substrate is not clean - oil stains, oxide layers, and dust attached to the surface of the substrate such as aluminum strips will form an isolation layer between the adhesive layer and the substrate. Even if the temperature of the butyl rubber is suitable and the flowability is good, it cannot fully adhere to the substrate. Secondly, the wrong choice of butyl rubber model is necessary. Hollow glass with different environments and requirements needs to be matched with the corresponding butyl rubber model. If the rubber type is not suitable for the scene, even if the parameters of the coating machine are adjusted accurately, it is difficult to ensure the bonding effect. In addition, improper control of the coating thickness and uniformity of the coating machine, or a humid operating environment, can also lead to situations where the substrate does not stick despite appearing to be at a suitable temperature.

　　解决方案一：做好基材预处理，筑牢粘接基础。这是解决问题的关键第一步，也是丁基胶涂布机操作前的必要准备。针对铝条等基材，要先用专用清洗剂配合擦拭工具彻底清洁表面，重点去除油污、氧化层和灰尘，避免残留杂质影响粘接。这里要提醒大家，清洁后的基材一定要晾干或烘干后再送入丁基胶涂布机，不能带着水渍或清洗剂残留涂胶。有条件的厂家，还可以在清洁后增加基材表面活化处理环节，进一步提升丁基胶的粘接附着力，从源头避免不粘问题。

　　Solution 1: Prepare the substrate well and build a solid adhesive foundation. This is the crucial first step in solving the problem and a necessary preparation before operating the butyl rubber coating machine. For substrates such as aluminum bars, it is necessary to thoroughly clean the surface with a specialized cleaning agent and wiping tool, focusing on removing oil stains, oxide layers, and dust to avoid residual impurities affecting adhesion. Here we would like to remind everyone that the cleaned substrate must be air dried or dried before being sent to the butyl rubber coating machine, and cannot be coated with water stains or residual cleaning agents. Conditional manufacturers can also add a substrate surface activation treatment after cleaning to further enhance the adhesion of butyl rubber and avoid non stick problems from the source.

　　解决方案二：选对丁基胶型号，匹配生产场景。丁基胶的型号直接影响粘接效果，和丁基胶涂布机的参数设置同等重要。如果是在低温环境下生产，要选用耐低温型丁基胶，避免胶层在低温工况下变硬失去粘性；若是生产高要求的中空玻璃，比如用于高层建筑、严寒地区的产品，建议优先选用优质丁基胶，这类胶的粘性和稳定性更有保障，像欧亚德新材料的丁基胶就很适合这类场景。选胶时还要注意查看胶的保质期，过期胶哪怕温度适宜，粘接性能也会大幅下降，这一点容易被忽视。

　　Solution 2: Choose the right butyl rubber model and match it with the production scenario. The type of butyl rubber directly affects the bonding effect, which is equally important as the parameter settings of the butyl rubber coating machine. If it is produced in a low-temperature environment, low-temperature resistant butyl rubber should be selected to avoid the adhesive layer becoming hard and losing its viscosity under low-temperature conditions; If producing high demand insulated glass, such as products used in high-rise buildings and cold regions, it is recommended to prioritize the use of high-quality butyl rubber. This type of rubber has better adhesion and stability, and butyl rubber from Eurasia New Materials is very suitable for such scenarios. When selecting adhesive, it is also important to check the shelf life of the adhesive. Even if the temperature is suitable, the adhesive performance of expired adhesive will significantly decrease, which is easily overlooked.

　　解决方案三：优化涂布机操作，把控工艺细节。丁基胶挤出温度适宜只是基础，还要通过涂布机精准控制其他工艺参数。首先是涂胶厚度和均匀度，通过调节涂布机的出胶量和输送速度，确保胶层厚度均匀且达标，太薄或局部缺胶都会导致粘接不牢，建议根据基材尺寸和生产要求，提前校准涂布机参数。其次是涂胶时的加压控制，在丁基胶涂覆后，通过涂布机的加压机构适当加压，让胶层与基材充分接触，排出间隙中的空气，提升粘接效果。另外，要避免在潮湿环境下操作涂布机，车间湿度建议控制在合理范围，湿气会影响胶层的固化和粘接。

　　Solution 3: Optimize the operation of the coating machine and control the process details. The suitable extrusion temperature of butyl rubber is only the foundation, and other process parameters need to be accurately controlled through the coating machine. Firstly, it is about the thickness and uniformity of the adhesive coating. By adjusting the dispensing amount and conveying speed of the coating machine, the adhesive layer thickness can be ensured to be uniform and meet the standard. Thin or locally lacking adhesive can lead to weak bonding. It is recommended to calibrate the coating machine parameters in advance according to the substrate size and production requirements. Next is the pressure control during adhesive coating. After the butyl adhesive is coated, the pressure mechanism of the coating machine is used to apply appropriate pressure, allowing the adhesive layer to fully contact the substrate and exhaust the air in the gap, thereby improving the bonding effect. In addition, it is recommended to avoid operating the coating machine in a humid environment. The humidity in the workshop should be controlled within a reasonable range, as moisture can affect the curing and bonding of the adhesive layer.

　　还有两个实用提醒要分享给大家。一是定期维护丁基胶涂布机，确保设备处于良好运行状态——检查涂布机的出胶口是否堵塞、加压机构是否正常工作，避免因设备故障导致涂胶不均；二是建立标准化操作流程，在丁基胶涂布机旁张贴操作规范，明确基材清洁要求、胶种选择标准、涂布参数设置等，让操作人员有据可依，减少人为失误。比如可以规定，每天开机前先检查丁基胶型号和保质期，清洁基材后必须经检验合格才能送入涂布机。

　　There are two practical reminders to share with everyone. One is to regularly maintain the butyl rubber coating machine to ensure that the equipment is in good operating condition - check whether the glue outlet of the coating machine is blocked and whether the pressure mechanism is working properly to avoid uneven coating caused by equipment failure; The second is to establish standardized operating procedures, post operating specifications next to the butyl rubber coating machine, clarify substrate cleaning requirements, adhesive selection standards, coating parameter settings, etc., so that operators have a basis to rely on and reduce human errors. For example, it can be stipulated that the butyl rubber model and shelf life should be checked before starting up every day. After cleaning the substrate, it must be inspected and qualified before being sent into the coating machine.

　　总结下来，丁基胶挤出温度适宜却不粘基材，并非设备或胶本身的核心问题，而是基材清洁、胶种匹配、涂布工艺等环节的细节没把控好。结合丁基胶涂布机的操作，做好基材预处理、选对丁基胶型号、优化涂布工艺参数，就能有效解决这一问题。对中空玻璃生产厂家来说，规范丁基胶涂布机的操作流程，重视每个粘接环节的细节，才能提升产品的密封性能和使用寿命。如果大家在实际生产中还遇到相关难题，建议咨询丁基胶涂布机或丁基胶厂家的专业技术人员，获取精准的解决方案。

　　In summary, the reason why butyl rubber extrusion temperature is suitable but does not stick to the substrate is not the core problem of the equipment or the adhesive itself, but rather the lack of control over the details of substrate cleaning, adhesive type matching, coating process, and other aspects. By combining the operation of the butyl rubber coating machine, doing a good job in substrate pretreatment, selecting the right type of butyl rubber, and optimizing the coating process parameters, this problem can be effectively solved. For manufacturers of insulating glass, standardizing the operation process of butyl rubber coating machines and paying attention to the details of each bonding process are necessary to improve the sealing performance and service life of the products. If you encounter any related difficulties in actual production, it is recommended to consult professional technical personnel from butyl rubber coating machines or butyl rubber manufacturers for accurate solutions.
