A Synthesis of a Dust Suppressant Using the Cellulose Extracted from Maize Straw

Abstract

In this paper, a cellulose‐based dust suppressant is synthesized using common maize straw as the raw material. In order to obtain high‐quality cellulose, a chemical, acid‐based treatment is employed for the extraction of cellulose and the removal of hemicellulose and lignin. By using polyvinyl alcohol (PVC) as a monomer, potassium persulfate (K2S2O4) as an initiator, aluminum hydroxide (Al(OH)3) as a crosslinker, and glycerol (C3H8O3) as a plasticizer (mass ratios of 28.5%, 1.0%, 0.5%, and 19.0%, respectively), the polyvinyl alcohol grafted cellulose dust suppressant is fabricated in a water bath of 70 ˚C after 5 h. The characteristics of the dust suppressant are measured using a Fourier transform infrared spectrometry, scanning electron microscope, thermogravimetric analyzer, universal testing machine, and wind tunnel simulation platform. At a concentration of 5%, the dust suppressant demonstrates some excellent functionality, such as economic rationality, film‐forming capability, compression resistance, temperature adaptability, and wind erosion resistance. As the raw material is easy to obtain and pollution‐free, this new dust suppressant has promising market prospects.

Cellulose Isolated From Waste Rubber Wood and Its Application in PLA Based Composite Films

“…To date, numerous species of lignocellulosic wastes (e.g., bagasse, cornstalk, coconut husk, etc.) have been attempted for isolation of cellulose ( Ditzel et al, 2017 ; Tuerxun et al, 2019 ; Wu et al, 2019 ; Ejaz et al, 2020 ; Kian et al, 2020 ; Wang H. et al, 2020 ) and meanwhile the obtained cellulose could be further processed for high-value utilization.…”

“…Hainan is the largest production base of natural rubber in China and annually a vast amount of rubber wood (RW) wastes from both rubber plantation and rubber processing industry has been generated without efficient utilization. Therefore, rational development of this type of cellulose-rich feedstock not only mitigates the atmospheric pollution caused by conventional incineration of lignocellulosic wastes, but also excavates the intrinsic value of natural polymers present in biomass wastes for conversion of high value-added products ( Abdulkhani et al, 2014 ; Wu et al, 2019 ; Wang H. et al, 2020 ).…”

Environmentally Friendly Methylcellulose-Based Binders for Active and Passive Dust Control

“…Cellulose is the most abundant biopolymer with global reserves of up to 75 billion tons obtained from a variety of sustainable sources, such as wood, plants, agricultural residues, and algae. , Moreover, engineered celluloses are available by reacting hydroxyl groups (−OH) on the d -glucopyranose ring-based backbone with various reagents, such as acetic acid, acetic anhydride, mineral acid catalyst, and alkyl/silyl chlorides (bromides, oxiranes, or vinyl compounds). − In addition, the hydroxyl groups contribute to form hydrogen bonds with oxygen atoms on adjacent molecules, providing water-retaining and adhesive nature. Due to these features and the safety of biopolymers to humans and the environment, cellulose and its derivatives are widely used as a binder, thickener, emulsifier, and dispersing agent in various applications, such as food, cosmetic and personal care, pharmaceutics, construction, and agriculture. , Although celluloses have been studied to use for dust suppressants and filters, utilized chemical additives to improve dust control efficiency is still a risk factor. , Therefore, we determined to identify engineered celluloses that can improve dust control effectiveness without any additional supplements.…”
