Description

Cleaning brush with washing and friction decontamination functions and preparation method and application thereof

Technical Field

The present invention relates to a flexible cleaning pad having a scrubbing portion and a method of making the same.

Background

In the united states, the cost of food-borne diseases is estimated to be $ 4 to $ 60 billion (1988). Cross-contamination of kitchen surfaces with contaminated meat products has been demonstrated. The raw meat-contaminated articles include sinks, dishcloths and chopping boards.

The household wipes contain up to 10 bacteria, including several members of the enterobacteriaceae family. Studies have shown that contaminated clothing may transfer bacteria to hands or clean surfaces in sufficient numbers to represent possible infections when in contact with food; see Rusin p., Orosz-Coughlin p., and Gerba C. (1998). Reduction of fecal coliform, coliform and heterotrophic bacteria plates bacteria were counted in domestic kitchens and bathrooms by disinfection with hypochlorite cleaners. 819. sup. 828 in the journal of microbiology 85 (9).

Most household cookware is made of stainless steel, enameled cast iron or aluminum, with or without a non-stick coating. These cookware can be damaged by using a scrubber that is too abrasive (such as steel wool, sandpaper or ultra-strong cleaners). Damaged cookware is therefore a significant cost in food management, i.e. up to 10% of the required capital cost; see Towen, Ewen CD. "economic losses due to outbreaks of food epidemics associated with food service establishments. "journal of food protection 48.2(1985): 169-" 180.

A household washcloth having all three parameters, which (i) is hygienic and does not allow pathogen growth; (ii) (ii) cleaning of effective and easy cookware with water and soap, and (iii) cookware such as burnt pens and pots, remains a long-felt unmet need.

Compression molding is commonly used to produce rubber and silicone parts economically and efficiently. Compression molding is a molding process in which a molding material, which is usually preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug and pressure is applied to force the material into contact with all mold areas while maintaining heat and pressure until the molding material solidifies. The silicone compound also requires an oven post cure to fully cure.
