“…Effect of CaCO 3 on the viscosity of resin glue and on the decomposition of NH 4 HCO 3 CaCO 3 affected the viscosity of resin glue. The maximum content of CaCO 3 was suggested to be controlled within 65.00 phr for UPR [16]. In this study, the content of CaCO 3 was controlled no more than 35.00 phr, considering the motion and the distribution of bubbles (which were caused by decomposition of NH 4 HCO 3 ) in resin glue.…”

Incorporation of different fine grain calcium carbonate into CaCO 3 /low-density unsaturated polyester resin (LDUPR) composites was studied and evident mechanical enhancement of CaCO 3 on composites was investigated. Preliminary experiment results indicated that proper content of CaCO 3 was less than 30.00 phr (parts per hundreds of resin), suitable preparation temperature range was from 72.0°C to 80.0°C, and initiator content was 1.80 phr. Optimal preparation conditions of CaCO 3 /LDUPR samples were obtained with the presence of 25.00 phr CaCO 3 and 2.50 phr NH 4 HCO 3 at 76.0°C based on preliminary experiments. The lowest apparent density of A-CaCO 3 /LDUPR composite was 0.53±0.02 g·cm −3 with a compressive strength of 20.27±0.51 MPa·g −1 ·cm 3 , and the highest specific compressive strength of the sample was 38.25±1.43 MPa·g −1 ·cm 3 . It is attributed to the hindrance to cross-linking between unsaturated polyester and styrene, and to the decrease of exothermic heat of the polymerization, which was caused by the existence of CaCO 3 . Unusual matrix microstructure with regular ripples and dimples formed by CaCO 3 , and the particular mechanical enhancement of regular ripples and dimples in composites were explored. 'CaCO 3 reefs' concept, reefs-induced ripples, dimples of streams flowing, and resolution of external force with major force further being consumed models comprised the regulated mechanical enhancement of CaCO 3 in CaCO 3 /LDUPR composites. This particular polymerization retarding and mechanical strengthening were obvious for the finest grain CaCO

“…Surface tension is measured by a drop shape analyzer (DSA100, Kruss, Germany), the viscosity is measured by a viscometer (AR2000ex, USA), and the permittivity is measured at 20 Hz by an impedance analyzer (Agilent E4990A, USA). The viscosities are adjusted by adding columnar calcium carbonate powder with a length of 1 μm to the epoxy resin. , Three different viscosities are formed by mixing in mass ratios of 1:1, 1:1.5, and 1:2, respectively. These liquid suspensions are labeled as LS 1–3.…”

In the electroinduced formation of a highly viscous liquid bridge, improving the efficiency of formation is important for industrial applications. This paper presents the preregulation method of the polarization status to shorten the formation time of a liquid bridge. The hindering effect of high viscosity on the polarization of liquid suspensions was investigated. The formation time of the liquid bridge is shortened, and stability is improved by prepolarizing the initial liquid film, with a maximum reduction in the average and standard deviation of times by 12.65 and 2.52 s, respectively. These effects are confirmed at different viscosities and voltages. In addition, this method has no obvious influence on the shape of the liquid bridge. This study provides an approach to improve the electroinduced formation.

In this study, the effects of CaCO3 and SiO2 nanoparticles on tensile strength of E-Glass fiber composite materials were investigated. Composite structures were produced by mixing CaCO3 nanoparticles into 3%, 5% and 10% by weight, SiO2 nanoparticles into 1%, 3% and 5% by weight epoxy resin. High nanoparticle rates are due to the large diameter of the powders and the desire to form a darker resin. In addition, different fiber orientations were used to emphasize inclusion of nano-additive materials into the resin in case of a decrease in the number of unidirectional fibers. Samples prepared according to the ASTM D3039 Standards were tested by uniaxial tensile machine, Instron 8801. Scanning electron microscopy analysis were performed and failure was mainly caused by debonding and clumping of fibers and fiber/matrix failure. An inclusion of CaCO3 and SiO2 nanoparticles improved the strength of the glass fiber composite sandwich structures. The optimum amount of nano-particles supplemented with different ratios were determined as 3% for CaCO3 and 1% for SiO2. Sufficient enough nanoparticles inclusion increased the quality of the adhesion between fiber and matrices. The inclusion of nanoparticle additives in E-Glass fiber composite materials had a significant effect and positively affected the adhesion properties of the matrix. Bu çalışmada, CaCO3 veSiO2 nano parçacıkların E-Cam elyaf kompozit malzemelerin çekme dayanımı üzerindeki etkileri araştırılmıştır. Kompozit plakalar, CaCO3 nano parçacıkların ağırlıkça %3, %5 ve%10, SiO2 nano parçacıkların ağırlıkça %1, %3 ve%5 oranında epoksi reçineye karıştırılmasıyla üretilmiştir. Yüksek nano parçacık oranları, tozların geniş çapından ve daha koyu bir reçine oluşturma arzusundan kaynaklanmaktadır. Ek olarak, tek yönlü elyaf sayısında azalma olması durumunda nano katkı maddelerinin reçineye dahil edilmesini vurgulamak için farklı elyaf oryantasyonları kullanılmıştır. ASTM D3039 Standartlarına göre hazırlanan numuneler tek eksenli çekme test cihazı, Instron 8801 ile test edilmiştir. Taramalı elektron mikroskobu analizler yapılarak hasarların liflerin bağlarının ayrılması ve kümelenmesi ve elyaf/matris bozulması olarak gerçekleştiği görülmüştür. CaCO3 ve SiO2 nano parçacıkların dahil edilmesi, cam elyaf kompozit sandviç yapıların dayanımını arttırmıştır. Farklı oranlarda takviye edilmiş optimum nano parçacık miktarı CaCO3 için%3 ve SiO2 için%1 olarak belirlenmiştir. Yeterli nano parçacık ilavesi, fiber ve matrisler arasındaki yapışma kalitesini geliştirmiştir. Nano parçacık katkı maddelerinin E-Cam elyaf kompozit malzemelere dahil edilmesi önemli bir etkiye sahipti ve matrisin yapışma özelliklerini olumlu yönde etkilemiştir.
