Chemical & Physical Data:
A mixture of unhairing enzyme and auxiliary
DOWELLON UHE has good unhairing and fibre opening up capability, it helps to loosen hair-root, remove hair, epidermis and open up collagen fibre simultaneously.
The application pH of DOWELLON UHE is 6.5-10.0
DOWELLON UHE can be used in soaking, enzyme unhairing system and enzyme paste for pig skins. Its unhairing and fibre open up capability comes stronger with the increase in percentage, temperature and prolonged treatment time. Extended time can have a risk of damaging the grain, therefore it is recommended to add a bactericide such as DOWELLIT FMN which has no negative effect on the activity of DOWELLON UHE.
For long-time treatment, we suggest to maintain the pH range 7.5-9.5.
The following dosages are suggested based on salted weight
In soaking process: 0.1%-0.3%
In enzyme paste for butt area of pig skins: 0.4%-0.8%
In enzyme unhairing system: 0.2%-0.5%
In environmental friendly unhairing system, the hides are pre treated by adding 0.3%-0.6% unhairing enzyme DOWELLON UHE for 1-2 hours time, followed by 1%-2% DOWELLON UHA and 0.5%-1.0% DOWELLON UHB, add 1.5%-2.5% sodium hydroxide and 0.5%-1.0% DOWELLON OPF as the next step to achieve satisfactory results in unhairing and open up of collagen fibre.
