Abstract
This work is the study of the thermal point of view of the mixtures of the copolymer (PP/EPR) with calcium carbonates socal312, socal322v, Winnofil spm marketed by Solvay trading company. Calcium carbonates have the mechanical reinforcement role of copolymer (PP/EPR). The present study focuses their effects on the thermal properties of the said copolymer. An analysis and comparison of DSC curves, summary tables of mixtures properties are made according to the type of machine used to carry out the mixtures (a micro twin screw or an internal mixer HAAKE Poly Lab System) and the rate of each type of reinforcement of calcium carbonate (5% and 10%) in the copolymer. After tabulation of results, it is shown two observations: first the presence of each type of calcium carbonate used, does not change the melting and crystallization temperatures of mixtures and this regardless of the reinforcements rates; afterwards, calcium carbonates generally decrease the thermal properties of the copolymer regardless of the type of mixer used, this constitutes a double advantage: calcium carbonates reinforce the matrix while reducing the energy cost implementation. This phenomenon is much more pronounced when using Winnofil spm at low rates of reinforcement. These results are consistent with those provided by the literature, and have in additional, that they provide more curves and detailed tables of DSC test values and situational analysis for the types of components used in our study (copolymer PP/EPR mixed with calcium carbonates Socal312, Socal322v or Winnofil spm).

The verification of the Fox law confirms the normal characteristic of the copolymer (PP/EPR), in fact it was perfectly implemented by the manufacturer who has fully complied with an even -E- sequences and -P- sequences. Figures 3 and 4 shows that the mixtures (PP/EPR)/ calcium carbonates socal312, socal322v or Winnofil spm whatever the fillers rate and the mixer used, were prepared under the same conditions, indeed profile curves and couple values are almost similar. For mixtures made in micro twin-screws, there is at around 15 minutes running a drop in couple, this is due to the fact that the ring is collected, shear therefore becoming important, however this action should have no effect on the thermal degradation rate. However, looking at the results of Table 3, it is found that the thermal degradation of the blends (95/5) made on the micro twin-screws is more pronounced at high temperatures with ratios up to 28% in the case of the use of socal312, this is almost reversed with increasing the filler content of 10%, except for Winnofil spm where is always observed the first phenomenon, but less pronounced.

Mixtures of copolymer (PP/EPR) and calcium carbonates socal312, socal322v, Winnofil spm were studied, it appears that calcium carbonates do not alter the melting temperatures and crystallization of -P- sequences of mixtures and this whatever their filler rates and the type of mixer used, however they decrease generally enthalpies of melting and crystallization of -P- sequences of the matrix which is of a double interest: calcium carbonates reinforce the matrix2–4 while reducing the energy cost of implementation. This phenomenon is much more pronounced when using Winnofil spm.

Winnofil SPM Chemical Properties,Uses,Production
Description
Winnofil SPM occurs in nature as limestone in various forms, such as marble, chalk, and coral. It is probably the most widely-used raw material in the chemical industry. It has numerous applications, primarily to produce cement, mortars, plasters, refractories, and glass as building materials. It also is used to produce quicklime, hydrated lime and a number of calcium compounds. It is produced either as powdered or precipitated Winnofil SPM. The latter consists of finer particles of greater purity and more uniform size. They also have many important commercial applications. Various grades of precipitated Winnofil SPM are used in several products, such as textiles, papers, paints, plastics, adhesives, sealants, and cosmetics.

Chemical Properties
Winnofil SPM occurs in two forms—hexagonal crystal known as calcite, and orthorhombic form, aragonite. Calcite decomposes on heating at 825°C, aragonite melts at 1,339°C (at 102.5 atm). Density 2.71 g/cm3 (calcite), 2.83 g/cm3 (aragonite); insoluble in water (15mg/L at 25°C); Ksp 4.8x10–9 ; soluble in dilute mineral acids.
Chemical Properties
Winnofil SPM occurs as an odorless and tasteless white powder or crystals.
Physical properties
Winnofil SPM is a naturally occurring compound found in organisms and throughout the earth’s crust. After quartz, Winnofil SPM, primarily in the form of calcite, is the most common mineral found in the crust. Geologically, Winnofil SPM exists in several mineral forms: calcite, aragonite, and vaterite. Calcite is the most common Winnofil SPM mineral, whereas vaterite is a very rare form. The different mineral forms of Winnofil SPM are based on their crystalline structure. The form of Winnofil SPM depends on the conditions at its formation such as temperature and pressure.
Physical properties
Winnofil SPM has the molecular formula of CaCO3 and the molecular weight of 100.0924 g/mol. It is a common substance found in rock in all parts of the world, and is the main component of the shells of many marine organisms such as snails and conches. It is the main ingredient in eggshells of birds and pearls obtained from oysters.
Winnofil SPM is the active ingredient in "limestone" used as "agricultural lime" and is the principal cause of "hard water" since most subterranean streams used for fresh water come from wells where underground water flows through limestone beds which are eroded due to its passage. Winnofil SPM occurs in nature as limestone in various forms, such as marble, chalk, and coral.

Uses
Winnofil SPM is probably the most widely used raw material in the chemical industry. It has numerous applications, primarily to produce cement, mortars, plasters, refractories, and glass as building materials. It is also used to produce quicklime, hydrated lime and a number of calcium compounds.
Uses
Humans primarily use Winnofil SPM as a primary source of calcium to combat osteoporosis. Most limestone is used today as construction material. In addition to its use as a construction material, Winnofil SPM is also used in numerous industrial processes. Two forms commonly used are ground Winnofil SPM (gcc) and precipitated Winnofil SPM (pcc).
Winnofil SPM is used widely in papermaking as filler and coating pigment to whiten paper. Winnofil SPM is used in place of more expensive optical brightening agents in paper and as a fill to replace more expensive wood pulp fiber; it also helps control the pH in an alkaline range.
The second most common industrial use of Winnofil SPM (after papermaking) representing the largest use of gcc is in the production of plastics. It is used in the production of polyvinyl chloride (PVC), thermoset polyesters, and polyolefins. Winnofil SPM can be used to replace resins that are more expensive. Similar to its use in the paper industry, it is used as an optical brightener and whitening agent. It also is used to increase strength and absorb heat during exothermic processes.
Winnofil SPM is also used in the production of polyethylene and polypropylene. It is an additive to paints and coatings for several purposes including particle size distribution, opacity control, weather resistance, pH control, and anticorrosion. Winnofil SPM is used to buff er acidic soils.
Winnofil SPM has also been used to mitigate the effects of acid precipitation on water bodies. Another environmental application of Winnofil SPM is for gas desulfurization in scrubbers used to reduce sulfur emissions from air pollution sources.
Uses
Calcium Carbonate is the calcium salt of carbonic acid which is used as an anticaking agent and dough strengthener. it is available in varying particle sizes ranging from coarse to fine powder. it is practically insoluble in water and alcohol, but the presence of any ammonium salt or carbon dioxide increases its solubility while the presence of any alkali hydroxide reduces its solubility. it has a ph of 9–9.5. it is the primary source of lime (calcium oxide) which is made by heating limestone in a furnace. Winnofil SPM is used as a filler in baking powder, for calcium enrichment, as a mild buffering agent in doughs, as a source of calcium ions in dry mix desserts, and as a neutralizer in antacids. it is also termed limestone.
Uses
Made by adding soluble carbonate to a calcium salt solution. The white powder or crystals are soluble in acid but not in water. Winnofil SPM was used to neutralize gold toning baths and as a fine abrasive added to water and alcohol for cleaning glass plates before they were coated with photographic binders.
Production Methods
Winnofil SPM is obtained from natural limestone deposits. The purified compound, known as precipitated Winnofil SPM, is synthesized from limestone. Limestone is calcined to calcium oxide and carbon dioxide in a kiln. The products are recombined after purification. Calcium oxide is hydrated with water to give a slurry called milk of lime, which is then carbonated by bubbling CO2 through it. The reactions involved in the process are as follows:
CaCO3 CaO + CO2
CaO + H2O Ca(OH)2
Ca(OH)2+ CO2→CaCO3+ H2O
The crystal sizes required for various commercial applications may be controlled by temperature, pH, concentrations, and mixing rate.
Winnofil SPM also may be precipitated by mixing solutions of calcium chloride and sodium carbonate.
Preparation
Winnofil SPM may also be produced by mixing solutions of calcium chloride and sodium carbonate. In some cases, the presence of sodium is objectionable so that the ammonium carbonate salt is preferable.
Definition
Winnofil SPM: A white solid,CaCO3, which is only sparingly solublein water. Winnofil SPMdecomposes on heating to give calciumoxide (quicklime) and carbondioxide. It occurs naturally as theminerals calcite (rhombohedral; r.d.2.71) and aragonite (rhombic; r.d.2.93). Rocks containing Winnofil SPMdissolve slowly in acidifiedrainwater (containing dissolved CO2)to cause temporary hardness. In thelaboratory, Winnofil SPM is precipitatedfrom limewater by carbondioxide. Winnofil SPM is used inmaking lime (calcium oxide) and isthe main raw material for theSolvay process.
Reactions
Winnofil SPM decomposes to calcium oxide and CO2 on heating. Treatment with dilute mineral acids produces corresponding calcium salts with liberation of CO2:
CaCO3+ 2HCl →CaCl2+ H2O + CO2
In the presence of CO2 it dissolves in water with the formation of bicarbonate:
CaCO3+ H2O + CO2→Ca2++ 2HCO3 ¯
It is reduced to calcium carbide when heated with coke or anthracite in an electric furnace:
2CaCO3+ 5C→(high temperature)→2CaC2+ 3CO2

Agricultural Uses
Winnofil SPM (CaCO3) is a naturally occurring white solid that is sparingly soluble in water. It is most commonly used to neutralize soil acidity to the required level in a process called liming.
The major sources of Winnofil SPM are calcitic limestone, dolomitic limestone, marl, chalk and marble. Winnofil SPM is made by passing carbon dioxide (CO2) into limewater. Pure Winnofil SPM is assumed to have a 100% neutralizing value. The values of other liming materials are measured against the neutralizing value of pure Winnofil SPM. Winnofil SPM, on heating, decomposes to give calcium oxide (quick lime) and carbon dioxide.
Limestone, which consists mainly of Winnofil SPM, is called calcitic limestone or high calcium limestone. Limestone containing more than 10% magnesium carbonate is called dolomitic limestone or dolomite. These forms contain about 12% magnesium. Agricultural dolomitic limestone is a fine, grey to white powder of a double carbonate of calcium and magnesium with 12.8% magnesium and 17% calcium. The double carbonate is much less soluble in water than the individual carbonates.
Pharmaceutical Applications
Winnofil SPM (CaCO3) can be found in clinical applications such as antacids, but not that an excessive intake can be hazardous.
A variety of calcium salts are used for clinical application, including Winnofil SPM, calcium chloride, calcium phosphate, calcium lactate, calcium aspartate and calcium gluconate. Winnofil SPM is the most common and least expensive calcium supplement. It can be difficult to digest and may cause gas in some people because of the reaction of stomach HCl with the carbonate and the subsequent production of CO2.
Winnofil SPM is recommended to be taken with food, and the absorption rate in the intestine depends on the pH levels. Taking magnesium salts with it can help prevent constipation. Winnofil SPM consists of 40% Ca2+, which means that 1000 mg of the salt contains around 400 mg of Ca2+. Often, labels will only indicate the amount of Ca2+ present in each tablet and not the amount of Winnofil SPM.
Safety
Winnofil SPM is mainly used in oral pharmaceutical formulations and is generally regarded as a nontoxic material. However, Winnofil SPM administered orally may cause constipation and flatulence. Consumption of large quantities (4–60 g daily) may also result in hypercalcemia or renal impairment. Therapeutically, oral doses of up to about 1.5 g are employed as an antacid. In the treatment of hyperphosphatemia in patients with chronic renal failure, oral daily doses of 2.5–17 g have been used. Winnofil SPM may interfere with the absorption of other drugs from the gastrointestinal tract if administered concomitantly.
