  • an edible oil packaging film with improved barrier properties and heat sealability from cassia gum incorporating carboxylated cellulose nano Crystal Whisker
    Food Hydrocolloids, 2020
    Co-Authors: Lele Cao, Fansong Meng, Lijuan Wang
    Abstract:

    Abstract A cassia-gum (CG) based edible packaging film was reinforced with carboxylated cellulose nano Crystal Whisker (C-CNCW), which is a potential alternative for oil-bags. The effects of C-CNCW dosage on the films were investigated by analyzing the rheological property of the film-forming solutions, the mechanical, barrier, thermal stability and heat sealability of the films. The C-CNCW with a zeta potential of −48.5 mV was a long silk-like structure with the diameter of 3–10 nm. Rheological results manifested that all the film-forming solutions exhibited a shear thinning property and the addition of C-CNCW changed the interaction of CG chains. The FTIR results showed that no new chemical bonds formed between CG and C-CNCW. SEM indicated that the aggregation of C-CNCW occurred at the content of 6%. The addition of C-CNCW reduced the light transmittance from 63.43% to 51.91% at 500 nm, but improved the oil permeability, mechanical properties, and heat seal strength from 0.550 to 0.064 g mm m−2 day−1, 18.53–32.85 MPa and 1295.40–2218.78 N/m as the C-CNCW dosage increased from 0% to 4%, respectively. Therefore, CG film reinforced by C-CNCW is promising in oil packaging.

  • method for preparing ultra fine calcium sulfate Crystal Whisker by using phosphogypsum
    2012
    Co-Authors: Tian Xie, Cuixia Jin, Qin Jun, Yaozhu Tian, Zhanjin Xie, Shuhao Qin, Liping Yang, Jie Yu
    Abstract:

    The invention discloses a method for preparing ultra-fine calcium sulfate Crystal Whiskers by using phosphogypsum. The method comprises that the phosphogypsum is ultra-fine treated to powder with grain size of 0.1-100 mum, water is added into the powder to prepare slurry with weight percent of 5-15 percent, pH value is regulated to be 3-5, reaction is kept for 3-5h at 125-145 DEG C and under 2-3MPa, pumping filtration is conducted when the obtained product is hot, and the filtered product is dried at 120-250 DEG C to obtain the calcium sulfate Crystal Whiskers. Moreover, Crystal promoter withweight 0.10-0.20 time of the weight of the phosphogypsum and seed Crystal with weight 0.1-0.2 time of the weight of the phosphogypsum can be added. The invention has the advantages of low production cost, simple production method and good comprehensive performance.

    Co-Authors: Ma Baoguo, Zhi Zhenzhen, Jin Zihao, He Xingyang, Li Xianliang, Su Ying, Lu Wenda
    Abstract:

    The invention relates to a phosphogypsum-base self-leveling material and a preparation method thereof. The phosphogypsum-base self-leveling material is composed of the following raw materials in percentage by weight: 10-20% of beta-gypsum powder, 20-30% of high-strength gypsum powder, 30-40% of aggregate, 5-15% of phosphogypsum Crystal Whisker, 2-4% of ore powder, 3-8% of cement, 0.1-0.3% of retarder, 0.05-0.10% of water retention agent and 0.1-0.5% of water reducing agent. Compared with the existing gypsum-base self-leveling material, the phosphogypsum-base self-leveling material utilizes abundant industrial waste phosphogypsum. Compared with the existing phosphogypsum-base self-leveling material, the product provided by the invention has the advantages of high quality, higher folding strength and lower production cost.
