As a new environmental protection material door, KFC door is deeply welcomed by the market and consumers. Especially in cold winter, air leakage is easy to occur, which affects the mood of customers. So how to avoid it?

1.查找原因，及时。出现漏风大的原因是安装人员安装的问题，“千里之堤，溃于蚁穴”，如果安装不到位或安装人员不专 业，都会出现漏风的问题，因此要选择懂行的安装人员安装，安装完后要注意调试，使用中要注意维修，形成长效机制即可有效避免漏风。

1. Find out the cause and solve it in time. The reason for large air leakage is the installation personnel's installation problem. If the installation is not in place or the installation personnel are not professional, the air leakage problem will occur. Therefore, select professional and knowledgeable installation personnel for installation. Pay attention to commissioning after installation, pay attention to maintenance during use, and form a long-term mechanism to effectively avoid air leakage.

2.选择正规厂家生产的质量好的门。正规厂家一般具有质量可靠，售后服务完整的资质，质量没问题，如果肯德基门的质量不好会导致其密封性差，因而漏风。不要因一时便宜，而选择劣质漏风的肯德基门。

2. Select good quality doors produced by regular manufacturers. Regular manufacturers generally have the qualification of reliable quality and complete after-sales service. The quality is no problem. If the quality of KFC door is not good, it will lead to poor sealing and air leakage. Don't choose the low-quality KFC door because it is cheap.

3.售后服务要选择原装配件。肯德基门出现漏风肯定是密封不好，一方面是是使用时间较长，导致密封不好，另一方面密封条件不完整，没有使用原装配件，造成漏风。

3. Original accessories shall be selected for after-sales service. The air leakage of KFC door must be due to poor sealing. On the one hand, it has been used for a long time, resulting in poor sealing. On the other hand, the sealing conditions are incomplete and the original accessories are not used, resulting in air leakage.

因此，做好以上三点，可有效避免肯德基门的漏风问题，也延长了肯德基门的寿命，也达到让客户满意的目的。

Therefore, the above three points can effectively avoid the air leakage problem of KFC door, prolong the service life of KFC door and satisfy customers.
