警示带又称为埋地警示带或管道警示带，是以PE膜作为基带，根据设计要求进行版面印刷而成的一种用于防止埋地管道被误开挖的警示产品，其很基础的也是很重要的生产环节就是吹膜，下面厂家就为大家介绍一下其他方面的重要环节。

Warning tape, also known as buried warning tape or pipeline warning tape, is a warning product used to prevent buried pipelines from being excavated by mistake, which takes PE film as the baseband and and is printed according to the design requirements. Its basic and important production link is film blowing. The following factory will introduce other important links for you.

1、原料选购

1. Purchase of raw materials

警示带生产主要原料即为PE原生颗粒，选购过程中要根据石油、天然气行业相关对于警示带的技术要求进行对应选材，原料纯净，无其它杂质添加，否则会影响警示带的抗拉及抗撕裂强度。

The main raw material for the production of warning tapes is PE primary particles. During the purchase process, the corresponding material selection should be made according to the technical requirements of the oil and natural gas industry for warning tapes. The raw materials are pure and no other impurities are added, otherwise the tensile and tear strength of warning tapes will be affected.

2、生产前配料

2. Pre production ingredients

为了增加警示带的横、纵向拉伸要求，一般会增加一定比例的线性材料，不可多也不可少，多了成本拉加，少了则强度不够。

In order to increase the horizontal and vertical stretching requirements of warning tapes, a certain proportion of linear materials will generally be added, which cannot be more or less. If the cost is more, the strength is not enough.

3、原料烘干

3. Raw material drying

原料烘干了是比较重要的环节，生产材需要对进料进行5-8小时的烘干，温度要控制合适，烘干过程中要随时观察含水率，如果原料含有水分，生成生来的产品质量肯定不合格。

The drying of raw materials is an important link. The production materials need to be dried for 5-8 hours. The temperature should be controlled appropriately. During the drying process, the moisture content should be observed at any time. If the raw materials contain moisture, the quality of the products produced must be unqualified.

4、吹膜机模口控制

4. Mold mouth control of film blowing machine

可探测警示带在半成品时为桶状，需要分切才能成为印刷前的半成品，所以一定要控制好模口，不然会出来警示带宽度及厚度出现偏差，上差则成本增加，下差则达不到客户要求。

The detectable warning tape is barrel shaped in semi-finished products and needs to be cut to become semi-finished products before printing, so we must control the die mouth, otherwise there will be deviation in the width and thickness of the warning tape, the upper difference will increase the cost, and the lower difference will not meet the customer's requirements.
