Pectins are polysaccharides with a molecular weight range from 20,000 to 400,000 daltons, depending on the number of carbohydrate monomers.2 Pectin is a fermentable fiber that results in the production of short-chain fatty acids and methane.6, 7 The simplest type of pectin is a linear polymer of galacturonic acid, a water-soluble …
Kaolin is a plastic raw material, particularly consisting of the clay mineral kaolinite. The chemical formula is Al2O3.2SiO2.2H2O (39.5% Al2O3, 46.5% SiO2, 14.0% H2O). In systemic mineralogy, kaolinite ranks among phyllosilicates, which are stratified clay minerals formed by a net of tetrahedral and octahedral layers.

There were no differences in the Celite and kaolin ACT measurements after heparin and 5 min after the start of CPB. The postoperative concentration of D-dimers was lower, but this was not the case for F1.2 fragments. Postoperative chest tube loss was also lower but had no effect on blood transfusion requirements (Table 3).
Results: The total heparin dose per patient in the 48 Celite-guided patients was 35 271 ± 12 406 IU with 51 supplements and in the 49 kaolin-guided patients, 35 997 ± 11 540 IU ( P = 0.77) with 56 supplements ( P = 0.53). Postoperative thrombin generation time, fibrinolytic response time, chest tube loss and transfusion requirements were not ...

Appl. Clay Sci., 6:87-119. Kaolins are white raw materials, their essential constituent being fine grained white clay, which are amenable for beneficiation that make them ideal for an assortment of industrial applications. Kaolin deposits can be classified into two types, primary (residual) and secondary (sedimentary).
centrifuge, rotary vacuum filter, or tube filter. The filtered dewatered slurry material may be shipped or further processed by drying in apron, rotary, or spray dryers. Following the drying step, the kaolin may be calcined for use as filler or refractory material. Multiple hearth furnaces are most often used to calcine kaolin.

Kaolin in contact with plasma can lead to the activation of the intrinsic blood coagulation cascade by binding the clotting factor XII to a negatively-charged kaolin surface via positively charged amino acids in its chain (Ngah & Fatinathan, 2008). Such a binding supposedly leads to subtle conformational changes in FXII, resulting in the ...

Kraft lignin is an abundant natural resource, but it is underutilized. In this study, sulfoalkylated lignin derivatives with similar charge densities but with different alkyl chain length were produced via sulfobutylation and sulfomethylation reactions. The contact angle studies revealed that sulfobutylated lignin (SBL) with longer alkyl chains had a …
As kaolin binds to polymers during processing, it naturally enhances mechanical properties, including strength, impact and flexibility. Kaolin gives plastics and rubbers desirable properties, like better resistance to tears and abrasions. It also improves these products' tensile strength and prevents warping.
