Glass aluminum curtain wall fire protection design requirements

[China Aluminum Network] When the glass aluminum curtain wall is subjected to fire or heat, it is easily broken, even causing a large area of ​​broken accidents, resulting in the rapid spread of fire, resulting in a large fire, endangering the safety of people and property, the so-called "Ignition" Wind way. In view of the actual practice of aluminum curtain walls for high-rise civil buildings at home and abroad, and the experiences and lessons of fire, partitions are made between non-combustible materials such as rockwool, mineral wool, glass wool, and aluminum silicate in the glass partition walls and window frames.

The general requirements for glass aluminum curtain wall fire protection are as follows:

(1) Non-burning materials should be used for the filling material of window walls and window walls. When the outer wall surface of the non-burning body with a fire-resistance limit of not less than 100 h, the hard-burning material may be used as a filling material for the wall.

(2) Non-combustible solid skirt walls with a fire-resistance limit of not less than 100h and a height of not less than 0.8m shall be provided on the outer edge of each floor of the glass curtain wall without window partitions and window curtain walls.

(3) The gap between the glass curtain wall and each floor slab and partition wall shall be filled with non-burning materials.

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 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.
