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，及時。出現漏風大的原因是安裝人員安裝的問題，“千里之堤，潰于蟻穴”，如果安裝不到位或安裝人員不專 業，都會出現漏風的問題，因此要選擇懂行的安裝人員安裝，安裝完后要注意調試，使用中要注意維修，形成長效機制即可有效避免漏風。

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.選擇正規廠家生產的質量好的門。正規廠家一般具有質量可靠，售后服務完整的資質，質量沒問題，如果肯德基門的質量不好會導致其密封性差，因而漏風。不要因一時便宜，而選擇劣質漏風的肯德基門。

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.售后服務要選擇原裝配件。肯德基門出現漏風肯定是密封不好，一方面是是使用時間較長，導致密封不好，另一方面密封條件不完整，沒有使用原裝配件，造成漏風。

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，做好以上三點，可有效避免肯德基門的漏風問題，也延長了肯德基門的壽命，也達到讓客戶滿意的目的。

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.
