ABSTRACT Specialty natural rubber (SpNR) latex, namely, deproteinized (DPNR) latex and epoxidized (ENR) has been produced to meet specific product's requirements. However, SpNR is normally used in the form of block manufacture dry products such as tires automotive parts. The applications into foam will be diversified. Findings indicate that foamability lower compared normal (LATZ) but shows lon...

Hydrocolloids, often called gums that generally contain many hydroxyl groups and may be polyelectrolytes .Foams are colloidal systems in which tiny air bubbles are dispersed in an aqueous continuous phase. Many processed foods consumed daily are liquid or solid foams, such as the head of soft drinks and beer, whipped cream, mousses, meringue, bread and ice cream. The utilization of these gums d...

The electric arc furnace (EAF) has the potential to significantly contribute decarbonization of iron and steel industry. However, during EAF steelmaking, carbon still needs be injected into molten slag initiate foaming, which is beneficial energy efficiency protection furnace. To move away from fossil carbon, biocarbon gained attention as an injection agent. In this study, two biochar candidate...

Conduct an analysis of scientific periodicals regarding the use and improvement fire extinguishing efficiency compression foam. The work was carried out on basis periodicals, experimental studies scientists from European Union, USA, China other countries, results which were presented in publications, conferences reports. Conclusions. An publications devoted to foam firefighting increasing its f...

This study used ethylene-propylene diene monomers (EPDM), an elastomer, to develop foams incorporating clay as filler using simple compounding, chemical foaming, and peroxide-mediated light crosslinking methods. The low-temperature batch mixer was employed for compounding azodicarbonamide (ADC) a foaming agent, dicumyl peroxide (DCP) crosslinker, followed by compression molding sheet preparatio...

the main factor affecting the economics of foam-assisted water alternative gas (fawag) process isthe loss of foaming agent by adsorption onto reservoir rocks. in this study, the effects of phases,surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density wereinvestigated by special adsorption experiments. moreover, a series of fawag tests were performedto examin...

Porous structure has wide application in industry due to some of its unique properties such as low density, low thermal conductivity, high surface area, and efficient stress transmission. Both templating and foaming agent methods have been used to fabricate porous structures. However, these methods can only fabricate simple geometries. In recent years, many studies have been done to use additiv...

The synthesis of high performance polyimide foams by the solid-state powder foaming of poly(amic acid) powders, containing hydrogen bonded blowing agent (THF), is described. During the thermal inflation of poly(amic acid) particles into polyimide microspheres, their fusion has been shown to produce the desired cellular architecture. In the present work, the solid state powder foaming process is...

The aim of this study was to develop a solvent-free polylactic acid (PLA) open-cell porous scaffold for bone tissue engineering using compression molding and new chemical foaming compound, that we named CFCO. latter is composed blend PLA azodicarbonamide (ADA) as agent, with the addition chitosan-grafted (CS-g-PLA) copolymer at various concentrations. novelty approach during foaming, is, decomp...

Anaerobic digestion foaming has been encountered in several sewage treatment plants in the UK. Foaming has raised major concerns for the water companies due to significant impacts on process efficiency and operational costs. Several foaming causes have been identified over the past few years by researchers. However, the supporting experimental information is limited and in some cases absent. Th...
