“…10 shows the variation of Young's modulus with diatomite weight fraction (Φf). It can be seen that the value of the modulus of elasticity increases non-linearly with the increasing weight fraction of the modified filler [29]. According to Hu et al [30], the slipping of macromolecular chains of the matrix is blocked by the inorganic filler particles.…”

The present study deals with the effect of the Diatomite (D) microcomposite with and without chemical modification in a polypropylene (iPP) blend. The objective is to achieve a material with a better performance at a lower cost and more accessible and more suitable processing. The chemical surface modification of Diatomite (MD) was achieved using a crosslinking system based on a mixture of sulfur, accelerator, and peroxide. The iPP/Diatomite composite was prepared by batch melt mixing in a Brabender Plasti-Corde under intense shearing at high temperatures and varying the Diatomite content from 0 to 15 wt%. The rheological behavior was examined by monitoring the Brabender Plasti-Corde torque/time rheographs. Different techniques were used to characterize the sample: Fourier transform infrared spectroscopy (FTIR), WAXS, SEM, and DSC. In addition, tensile strength tests and impact strength mechanical tests were conducted to study the performance. It was found that chemical modification strongly affected rheological behavior and generated a new rheological characteristic compared to the composites without modification. This has induced a new structure form that has improved mechanical properties. Moreover, the chemical modification used and due to its simplicity, can be successfully used on an industrial scale with the appropriate process.

“…In addition, some scholars have found that diatomite has the effect of delaying the precipitation of the dripping agent. He et al 23 prepared microdiatomite-modified LDPE antifog film by blow molding method and studied the antifog performance and mechanical properties of the film. The results show that the film modified by inorganic micron diatomite with surface treatment agent has a more obvious antifog effect than that modified by antifog agent alone.…”

Adding an appropriate amount and the stable precipitation of surfactant on the inner surface of agricultural plastic greenhouse films can prevent the formation of water droplets on the inner surface of the film to reduce its harmful effects in the process of plant cultivation and production. In this work, for the stable precipitation of the surfactant glycerol monostearate, diatomite minerals from three origins in China were compared through structural analysis and adsorption performance. The effects of acid treatments and alkali treatments on the mineral structure were studied, and the adsorption mechanism of glycerol monostearate was further investigated. The results show that the structural characteristics of Jilin diatomite are more suitable as adsorbents for glyceryl monostearate adsorption. Because diatomite is resistant to acids but not alkalis, when diatomite is treated with an alkali, impurities on its surface can be removed and the hydroxyl group and specific surface area can be greatly increased. The adsorption capacity of glycerol stearate was increased to 218.4 mg/g, or 32.08%, over its pretreatment level. The results show that this is mainly the result of physical adsorption caused by van der Waals force imbalance and chemisorption caused by a small number of hydrogen bonds. In addition, the dripping performance of this composite dripping film with mineral diatomite was better than that of the commercial dripping film, which provided a theoretical basis for efficient mineral slow-release drip irrigation composite film.
