警示帶又稱為埋地警示帶或管道警示帶，是以PE膜作為基帶，根據設計要求進行版面印刷而成的一種用于防止埋地管道被誤開挖的警示產品，其很基礎的也是很重要的生產環節就是吹膜，下面廠家就為大家介紹一下其他方面的重要環節。

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、原料選購

1. Purchase of raw materials

警示帶生產主要原料即為PE原生顆粒，選購過程中要根據石油、天然氣行業相關對于警示帶的技術要求進行對應選材，原料純凈，無其它雜質添加，否則會影響警示帶的抗拉及抗撕裂強度。

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、生產前配料

2. Pre production ingredients

為了增加警示帶的橫、縱向拉伸要求，一般會增加一定比例的線性材料，不可多也不可少，多了成本拉加，少了則強度不夠。

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

原料烘干了是比較重要的環節，生產材需要對進料進行5-8小時的烘干，溫度要控制合適，烘干過程中要隨時觀察含水率，如果原料含有水分，生成生來的產品質量肯定不合格。

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、吹膜機模口控制

4. Mold mouth control of film blowing machine

可探測警示帶在半成品時為桶狀，需要分切才能成為印刷前的半成品，所以一定要控制好模口，不然會出來警示帶寬度及厚度出現偏差，上差則成本增加，下差則達不到客戶要求。

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.
