The analysis of thermoplastic characteristics of special polymer sulfur composite

Abstract

Specific chemical environments step out in the industry objects. Portland cement composites (concrete and mortar) were impregnated by using the special polymerized sulfur and technical soot as a filler (polymer sulfur composite). Sulfur and technical soot was applied as the industrial waste. Portland cement composites were made of the same aggregate, cement and water. The process of special polymer sulfur composite applied as the industrial waste is a thermal treatment process in the temperature of about 150-155 • C. The result of such treatment is special polymer sulfur composite in a liquid state. This paper presents the plastic constants and coefficients of thermal expansion of special polymer sulfur composites, with isotropic porous matrix, reinforced by disoriented ellipsoidal inclusions with orthotropic symmetry of the thermoplastic properties. The investigations are based on the stochastic differential equations of solid mechanics. A model and algorithm for calculating the effective characteristics of special polymer sulfur composites are suggested. The effective thermoplastic characteristics of special polymer sulfur composites, with disoriented ellipsoidal inclusions, are calculated in two stages: First, the properties of materials with oriented inclusions are determined, and then effective constants of a composite with disoriented inclusions are determined on the basis of the Voigt or Rice scheme. A brief summary of new products related to special polymer sulfur composites is given as follows: Impregnation, repair, overlays and precast polymer concrete will be presented. Special polymer sulfur as polymer coating impregnation, which has received little attention in recent years, currently has some very interesting applications.

The Use of Sulfur Waste to Protect Against Corrosion of Metal Implants

“…S µ has a higher molecular mass than S λ . S µ was obtained by treating colloidal state [2,6,[30][31][32][33] sulfur after boiling with water and Ca(OH) 2 and further precipitation with HCI. Later, hydrolysis with alcohol yielded S λ [30][31][32][33][34].…”

“…The information about the preparation of the polymerized sulfur composition and experimentally determined properties are presented in Tables 2, 3, and 4, respectively. The sulfur binder used for these investigations is shown in Figure 3 [1][2][3]6].…”

“…The special features of polymer sulfur composite are resistance toward aggressive aqueous solutions, high surface hydrophobicity (i.e., low water absorption), and relatively high adhesion to many surfaces, including metal surfaces [21,22,31]. Polymer sulfur composite is a highperformance thermoplastic material that is prepared by the thermal treatment (150-160 °C) of sulfur waste and additives [2,6,[23][24][25]31]. The suitable physicochemical properties of the polymer sulfur composites, such as chemical passivity, excellent resistance toward acids and salt solutions, and hydrophobic properties [17,18,26,31], find their application as a biocompatible surface coating material.…”

Evaluation of acid corrosion resistance of Portland cement composites impregnated with polymer sulfur composite

“…In no building material, structural element or building is everlasting). Generally speaking, the fight against corrosion comes down to providing a given material or element with protection whereby its failure-free service life is significantly extended (Książek, 2014a(Książek, , 2015a(Książek, , 2015b(Książek, , 2016b(Książek, , 2016cVlahovic et al, 2012).…”
