The bactericidal ability of Poly Hexamethylenebiguanide Hcl (PHMB) 20% solution is better than other bactericides. In particular, the product's unique long-term antibacterial effect and the ability to prevent secondary infection are not achieved by other fungicides.
Bactericidal mechanism:
Bacteria quickly suffocate to death after using Poly Hexamethylenebiguanide Hcl (PHMB) 20%. At the same time, because this product is a polymer structure, which can improve the effective activity of guanidine group, the bactericidal effect of Poly Hexamethylenebiguanide Hcl (PHMB) 20% soution is much higher than other guanidine compounds (such as chlorhexidine). Due to the special bactericidal mechanism of this product, all kinds of bacteria will not be resistant to it, which has been confirmed by the experiments of foreign authoritative testing institutions.
Features and advantages:
1. Long-acting nature:
After the solution of Poly Hexamethylenebiguanide Hcl (PHMB) is dried, a polymer thin layer of disinfectant is formed on the surface of the object, which can keep the state of the object after sterilization and prevent the secondary pollution of the object. Generally, the surfaces treated with aqueous solution of this product will remain sterile for up to three months.
2. Innocuity
As Poly Hexamethylenebiguanide Hcl (PHMB) 20% liquid is a high polymer, it is not easy to be absorbed by animal tissues, greatly reducing the toxicity, so that it has no effect on cells of higher organisms. In addition, the experiment proves that Poly Hexamethylenebiguanide Hcl (PHMB) 20% can be naturally degraded and will not cause pollution to the environment.
The test results of the microbial detection center: the LD50 of mice by gavage is more than 20900mg / kg (judgment standard: the higher the value of LD50 is, the lower the toxicity is, and the value greater than 5000mg / kg is actually non-toxic). The conclusion is that "2% of the product belongs to the actual non-toxic grade".
3. No irritation to skin:
The experimental study of Poly Hexamethylenebiguanide Hcl (PHMB) 20% on skin was carried out with rabbits. Conclusion: 2% of the product solution has no skin irritation when the skin irritation response integral value is 0. (judgment standard: the lower the integral value, the lower the stimulation.)
We specialize in wholesale and bulk amounts, ensuring all our clients have the right China Poly Hexamethylenebiguanide Hcl (PHMB) 20% manufacturer and supplier when they need it.
Special Applications of PHMB:
1. Paper making industry
In the process of papermaking and cardboard production, because Poly Hexamethylenebiguanide Hcl (PHMB) 20% is cationic polymer electrolyte, it can be used as an auxiliary agent to accelerate pulp dehydration and mineral filler precipitation, so as to strengthen and improve papermaking process. In addition, Poly Hexamethylenebiguanide Hcl (PHMB) can also stabilize the dispersion of paraffin and increase the size stability of paper. The hydrophobicity of paper and hardboard paper increases by 40-50%.
The activity also reduces some problems related to the accumulation of pulp in papermaking machinery, and can produce antibacterial paper for manufacturing health products (to replace the silver containing kursin paper). At the same time, Poly Hexamethylenebiguanide Hcl (PHMB) 20% also improves the physical properties of the paper: water absorption, strength after water, air permeability.
2. Agricultural application
As Poly Hexamethylenebiguanide Hcl (PHMB) 20% has the function of disease resistance and protection to plants, can effectively kill harmful bacteria, and is harmless to ecology, it is an environmental protection product, which makes the product completely applicable to all growth stages of various agricultural products: Treat seeds, bulbs or tubular seeds with 0.1-1% aqueous solution of PHMB. When the symptoms of vegetable diseases appear, spray with 0.01-0.1% Poly Hexamethylenebiguanide Hcl (PHMB) aqueous solution of the product (if necessary, add appropriate polyelectrolyte, such as polyacrylic acid).
If the source of infection is in the soil, it can be irrigated with 0.01% water solution in the amount of 50-100g per hectare (0.01g per square meter), or sealed with the product water solution (1-10kg per hectare).
In order to reduce the loss of storage in winter, 0.2% Poly Hexamethylenebiguanide Hcl (PHMB) aqueous solution of this product can be used to wash or spray vegetables and fruits. In addition, the product can overcome the damage of excessive herbicides to plants and prevent infection in the soil.
As a pesticide, the efficacy of this product is ten times higher than that of Benazolin, chlorothalonil and sodium disulfonate. Therefore, to achieve the same effect, the use amount of Poly Hexamethylenebiguanide Hcl (PHMB) 20% liquid is 10-30 times less. Moreover, it is safe, non-toxic and non irritating, especially harmless to people and animals.
3. Oil exploitation
In oil exploitation, a large number of bacteria, such as sulfate reducing bacteria, not only engulf the oil, but also degrade the polymer used (ordinary polymer with low molecular weight), reducing the efficiency of polymer flooding and increasing the cost.
