Technology of Floor Maintenance and Current Trends (ASTM by William J. Schalitz, editor

By William J. Schalitz, editor

This new ASTM e-book can provide the newest info on ALL points of ground polish in easy-to-understand phrases. Ten peer-reviewed papers hide: a radical overview of the chemistry fascinated with flooring polishes and linked coatings. Coating upkeep and static coefficient of friction (COF) comprises papers that sincerely outline COF and the way it really is measured safely in response to ASTM criteria. there's additionally a common assessment of polish upkeep options and a serious paper encompassing the connection among the static COF of newly utilized ground polish and that very same end, which has been subjected to numerous typical upkeep recommendations over the years. felony and regulatory concerns discusses the criminal facets linked to a slip prevalence, in addition to the instruments to avoid slip incidents. it's also a precise case heritage, which supplies a meticulous investigative define for these thinking about the invention part of a slip declare; and closes with a evaluate of these regulatory concerns that presently impact flooring polishes. STP 1448 might help amenities higher deal with their ground care application, saving them money and time, whereas enhancing the final visual appeal and protection. It has a large base of allure from the formula chemist constructing polishes to the amenities supervisor who's trying to greater deal with their ground care application.

Sample text

This concrete slab has been sealed on the left with a sealer typically used for vinyl composition tiles and on the right with a high performance, one component, aqueous sealer designed f o r concrete. Gasoline has been applied to the bottom half o f each side. The 'Mnyl composition '" tile sealer has been completely dissolved by the gasoline but the high performance, one component, aqueous-based sealer has not been affected. TYSAK ON WATER-BASED ACRYUG CONCRETE SEALS 47 The time required for the entire process may run anywhere from three to seven days, an interruption that can be most inconvenient for the operator of the facility.

Figure 2 - Transmission electron micrograph of an acrylic latex film (typical concrete sealer composition, formulated) "'stained" showing the bulkfilm structure. Average particle diameter was determined to be approximately 100 nanometers. What is Efflorescence? Efflorescence is a naturally occurring phenomenon that results from the hydration of cement, a component of concrete. Efflorescence is the deposit of salts on the surface of concrete, which is caused by leaching of minerals from the substrate by water.

In comparison, one component, aqueous acrylic based concrete sealers typically provide inter-coat adhesion, faster dry times and consequently recoat extremely well. Formulating and Application The aqueous, one package nature of thermoplastic aqueous-based vehicles makes formulation of sealers easy and straightforward. Formulation and processing techniques are similar to those encountered in the resilient floor finish industry; simple addition and agitation techniques are all that is required. End user requirements will dictate the characteristics required of the sealer and influence other raw material component choice.
