The image features hexagonal shapes and smiling faces representing molecules, surrounded by arrows pointing downward. Wavy lines in orange, yellow, and red suggest dynamic movement or flow. The design is minimalistic and uses a soft color palette.

1. 什么是尼龙6,6？

尼龙6,6（也称为聚酰胺66或PA66）是两种起始材料在压力和高温下结合形成一种称为聚合物的链，INVISSTA的客户用它制造产品。

The AA process features a yellow hexagon releasing particles into a container with yellow powder, while the HMD process shows a blue circle releasing droplets into a container with blue liquid. The setting is minimalistic with a flat surface and light blue background.

2. INVISTA在《尼龙》中的角色 6,6

在INVISTA，我们用这两种起始材料制造尼龙6,6：二酸（AA）和六甲二胺（HMD），而英维斯塔正是这种原料的制造。

3. 制作ADN——我们的流程

为了制造HMD，我们首先需要制造一种关键成分——脂腈（adiponitrile，简称ADN）。我们专有的ADN工艺以比现有竞争技术更少的能耗，创造出更优良的产品产率。

Visible text includes 'HMD!' and 'H2' on the characters, adding a scientific and whimsical touch. The design uses soft, muted colors with green and blue tones.

4. 制作头戴显示器

接下来，我们有一种通过利用催化剂将ADN氢化成HMD的工艺——这是尼龙6,6中第一个六碳分子。

5. 制盐

然后我们把头显与二酸或尼龙6,6中的下一个六碳分子混合。这会在水中形成盐溶液。

6. 施加压力

盐随后被高温高压加热，排出水分，使熔融的聚酰胺链得以延长和增强。

7. 制作颗粒

最后，我们将这些熔融聚酰胺挤出到冷水槽中，在那里凝固后送往切割机加工成尼龙6,6颗粒。
