Old
VAT dye VAT dye, insoluble in water, in the alkaline solution by sodium
dithionite reduction processing powder (insurance), and make the fiber
dyeing dye. Its fast and washing fastness especially, can be used for
cotton, linen, viscose, whalen fiber dyeing and printing, etc.
In
the molecular structure of VAT dye excluding sulfonic group, carboxylic
acid base, such as water soluble groups, insoluble in water, therefore,
cannot be directly dyed; The molecular conjugated double bond systems
containing at least two carbonyl, interaction with insurance powder in
the alkaline solution, carbonyl reduction into hydroxyl, become water
soluble compounds ─ ─ the leuco body. Is leuco body has affinity to
fiber, fiber after adsorption, oxidized by air or other oxidants, leuco
body back for VAT dye fixation on fiber staining. Leuco body staining
method shortcoming is dye into the fibers not easily, if the suspension
pad dyeing, the reduction of the outstanding dye made from suspension
solution, borrow machine rolling pressure make dye fine, evenly
distributed on the dyed fabric treated with insurance powder and make
dye reduction by fiber adsorption, good is thicker and uniform can be
obtained by the oxidation dyeing effect.
Its
chromatographic is full, bright color, soaping, tanning fastness are
high, but because the price is more expensive, some yellow, orange and
other color with photosensitivity brittle damage phenomenon, make its
application is limited by certain.
Because Vat Dyes does
not dissolve in water, so the side effects of it on the human body easy
to control, more safe and convenient for environmental protection, but
its cost is generally high.

Characteristics:
This valve is applicable for high-hardness grains or corrosive media containing soft grains. It's used as an on-off for hydraulic coal transportation, hydralic deslagging and cinder removal and slurry transportation pipelines, with the workint medium being slag water ratio higher >1:5 and the biggest grain ≤5mm. Its working nominal pressure is from PN10 to PN40, and applicable temperature is below 200 Deg C.
All medium-contacting parts are made of structural ceramic with extremely high chemical stability and hardness. Therefore, it has extremetly strong resistance to abrasion, corrosion and erosion, good heat insulation and small thermal expansion.
Its feed inlet is fully through without any blocks, and it has an anti-blcokage blwoing unit, with strong abrasion resistance, a good sealability, a small starting load and little ash seizure or accumulation.
It adopts a high-grade toughened structural ceramic seal, featuring high mechanical strength, strong abrasion resistance, a long service life and a compact structure, which can be installed at any angle.
Special ceramics is different from general ceramics, its hardness even more than steel,
second only to diamond, and corrosion resistant, high temperature resistant!!!!! "" metal
valve with long easy to produce the gap, ceramic valve is not. Because of wear-resisting,
anti-corrosive, sealing strong, ceramic water valve very water saving. "" our valves can be
used 500000 times, if every switch 60 times, can use 22.8 years, this is metal valve can not do it. "
