PLC industrial control and automation industry development

The rise of PLC in the 1970s was first applied in a large number of automotive assembly lines. In the 1980s, PLC matured and fully adopted micro-electronic processor technology, which was widely promoted and applied. The annual sales have always increased by more than 20%, which has laid an unshakable position in industrial control. In the 1990s, with the official promulgation of the industrial programming language IEC61131-3, PLC began its third development period.

The development of PLC products in China was in the mid-1970s. At that time, many research institutes, universities and factories in Shanghai, Beijing, Xi'an, Guangzhou and Changchun, and more than 20 units were developing and producing PLCs. Most are small PLCs). It is particularly worth mentioning that the State Science and Technology Commission and the former Ministry of Machinery Industry organized the "Sixth Five-Year Plan", "Seventh Five-Year Plan" and "Eighth Five-Year Plan" programmable controller sub-projects in the special project of instrumentation and key issues. Beijing Machinery Industry Automation Research Institute is responsible for the development of MPC-10, MPC-20, MPC-85 PLC.

In order to improve the technical level of China's PLC as soon as possible, and introduce advanced production technology of PLC, Sino-foreign joint ventures or wholly foreign-owned enterprises began mass production of PLCs in China. Siemens first opened a PLC manufacturing company in Dalian; the PLC produced by Omron in Shanghai was sold at home and abroad; the PLC of Jiangsu Wuxi Guangyang Electronics Co., Ltd., which became a sole proprietorship after the joint venture, has small, medium and large series products. Sino-foreign joint ventures and the introduction of technology have brought a new level of domestic PLC.

Fixative (dye-Fixing Agent)

Active Ingredient: Quaternary ammonium salt cationic surfactant
Chemical Name: Formaldehyde-free Fixing Agent
Chemical Family: PolyDADMAC

CAS No.: 26062-79-3

1.Formaldehyde-free Fixing Agent

2.Has no free formaldehyde,no peculiar smell,no irritation to skin, accord to eco request

[Description]:

Formaldehyde-free Fixative Color Fixing Agent is belongs to polymerization polyDADMAC, a cationic polymer. It can make up of macromolecular compound with dye, then achieve to improve soaping and rub fastness of fabrics. It can be used for color fixing for dyeing and printing of reactive dyed fabrics as cotton, linen, silk, and direct dyed fabrics.

[Specification]:

Appearance: Brownish yellow viscous liquid

Ionic character: Cationic

PH Value: 5-8 (1% aqueous solution)

Dissolution: Dissolve in cold water easily.

Composition: Special polymer compound

[Dilution Method]:

With 4-6 times the water and stir to dissolve dilution.

[Direction for Usage]:(To dilute finished product as an example)

A. Padding Process: 5-20g/L, temperature 40Â°C-60Â°C, PH Value:5-8, One-dip-one-nip or Double-dip-double-nip.

B. Dipping process: 1-4% (O.W.F), Room temperature 40Â°C-60Â°C, PH Value:5-8, bath ratio:1:8-12,Time: 20-30 min.

[Properties]:

1. Concentrated Formaldehyde-free Fixative Fixing Agent has good color fixing property, can obviously improve the dyeing or printing of fabric soaping, washing fastness and wet rubbing fastness.

2. Can be used for much of the association between dye fixation, anti fading property, does not affect the dyeing or printing of fabric vividness. No effect for the original feel, processing fabric has excellent hydrophilic.

3. Formaldehyde-free Fixative widely used for dyeing or printing of the direct, active dye fixing finishing, good fixation effect, especially for the red dye and Cuilan dyes, particularly prominent, fixation is better than the general Formaldehyde-free Fixative.

4. The dye PH value for a wide range, acid, alkali resistance, resistance to hard water, high temperature resistance, an environment-friendly products, does not contain formaldehyde.
