چکیده
The application of polytetrafluoroethylene (PTFE) coatings to metal surfaces is a well-known procedure carried out avoid fouling phenomena on food-processing surfaces. Fluorine-based polymers are generally chemically and thermally stable, thus allowing them be the preferred choice when designing anti-stick in food service industry. Their lifespan, however, depends environmental conditions. It well known that thermal ageing can affect properties PTFE reduce their mechanical, thermal, chemical causing failures contaminating food. main goal study identify different failure mechanisms occurring PTFE-based coatings, using both SEM/EDXS ATR FT-IR data reveal starting point degradation processing applications. results from this research preferential points for mainly polymer/substrate interfaces, polymer/filler or polymer matrix itself.

the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
Applications of Essential Oils in Food Preservation
Many food products are perishable by nature and require protection from spoilage during their preparation, storage and distribution to give them desired shelf-life. Because food products are now often sold in areas of the world far distant from their production sites, the need for extended safe shelf-life for these products has also expanded. Currently, there is a strong debate about the safety...
متن کاملStudying the Effect of the Concentration of PTFE Nanoparticles on the Tribological Behavior of Ni-P-PTFE Composite Coatings
In the past 30 years, electroless nickel (EN) plating has grown to such proportions that these coatings and their applications are now found underground, in outer space, and in a myriad of areas in between. Moreover, in order to further improve the mechanical and tribological properties of the nickel-phosphorous (Ni-P) coatings, Ni-P/PTFE composite coatings can be obtained, which provides even ...
