Shield cutters are widely used in urban subway construction. At present, there are more than 40 cities in China that are constructing subways. Shield cutters are a new type of industry with broad market prospects. However, the domestic shield cutter market is basically occupied by large foreign companies, and it is urgent to establish a self-owned brand.
China Railway Tunnel Group Tunnel Equipment Manufacturing Co., Ltd. is an important tunnel equipment manufacturing enterprise in China. Based on the technical advantages of Zhuhard Group, “Zhuzhu†has strong development and processing capabilities of shield cutter materials. According to the agreement, the two parties will share research results in the test platform and geological data to jointly build the largest shield R&D and manufacturing base in China.

[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 40°C-60°C, PH Value:5-8, One-dip-one-nip or Double-dip-double-nip.
B. Dipping process: 1-4% (O.W.F), Room temperature 40°C-60°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.
