HR Tanning Auxiliary Agent

 

Principal Compositions :
organic acid compound
Technical Criterion :

Appearance : A white to light gray powder

pH solution (10% solution ):8.0-9.0

solid content( mass ratio %):≥96.0

 

Properties:

HR is a kind of reactive fixating agent for chrome tanned leather and it doesn’t contain chrome.It can enhance the binding power between chrome and fiber ,improve the absorptivity of chrome ,decrease the use of chrome tanning agent and has some effect of basification.

HR is suiltable for all chrome-tanned leather ,it has no special requirement for soaking and liming before chrome -tanning process but the liming must be thoroughly completed, especially for a thick and tight pelt .

The liquor ration in tanning process should be small when use HR tanning system .First add chrome powder into drum ,run until the chrome penetrate completely , add HR into drum ,run at least 60min, then continue as usual processes.The total action time of HR is 8-12h.If the hide cann’t be fish out immediately after tanning ,the drum should hold running 10min/h or cool the drum temperature down to normal temperature by filling into enough water and run 15-20min ,otherwise chrome stain will form on leather and the crust would become wrinkled.

The blue tanned with chrome tanning agent with HR has light ,bright colour ,tight grain and plump feeling.

 

Package and reserving :

Net weitht 20kg/bag ;

Storing in a shady and dry place, avoid the dampness

Period of validity: 24months


Applications:

It is mainly used in the later chrome tanning process and the dose is 0.2-0.5% weight by pelt.It is especially used in the tanning and chrome retanning process of low-grade and empty hide.

The conditions for higher absorption of chrome in normal dosage :1)small liquor ration,2)the end pH of tanning is among 3.9-4.2;3)the end temperature of bath liquid is among 40-42 ℃ ;4) the total tanning time is 12h,at least not less than 9h;5) add HR as powder directly;6)the bath temperature should not higher than 30℃ before adding HR.

It is suggested that the blue should be washed by water of normal temperature(150% water ,25℃,run 5-10min)before fishing out if the blue will be stored for a period of time.
