国外混凝土用玻璃钢筋开发概况

混凝土是应用最广的建筑材料。混凝土通常采用钢筋来增加强度。在压力荷载下,钢筋混凝土性能卓越,但在拉伸荷载下它有变脆的趋势。混凝土养护时的拉伸应力易导致裂纹。裂纹会让水分进入,最终引起钢筋腐蚀。     

海藻酸凝胶性质对蛋白质扩散的影响

通过观察冷冻干燥海藻酸凝胶的断面扫描电镜(SEM)照片与卵清蛋白从海藻酸凝胶中的释放试验,分析了海藻酸凝胶性质对蛋白质在凝胶中扩散的影响。凝胶的SEM照片可见,海藻酸钙的冷冻干燥颗粒内为较大的圆孔,海藻酸锌凝胶内为较小的长孔,表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强;卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明,由于上述海藻酸锌凝胶的特性,导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强;根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1.19×10-7、0.07×10-7cm2/s,利用阻滞模型计算得海藻酸锌高分子链在凝胶颗粒中体积分率约为海藻酸钙高分子链在凝胶颗粒中体积分率的1.7倍。     

Alginate fibres: an overview of the production processes and applications in wound management

Alginate fibers are made from sodium alginate, which is a natural polymer extracted from brown seaweeds. Over the last two decades, alginate fibers have become well established in the wound management industry where their ion‐exchange and gel‐forming abilities are particularly useful for the treatment of exuding wounds. In order to deliver functional performances for advanced wound management products, many improvements have been made in recent years to enhance the absorption and gel‐forming capabilities and the anti‐microbial properties of alginate fibers. In addition, attempts have been made to use alginate fibers as a carrier to deliver zinc, silver and other active ingredients that are beneficial to wound healing. This paper reviews the development in the production of various fibers from alginate, and summarizes the production processes for calcium alginate, calcium/sodium alginate, sodium alginate, zinc alginate, silver alginate and other types of alginate fibers containing novel functional ingredients.

The conversion of calcium alginate fibers into alginic acid fibers and sodium alginate fibers

Alginate is a natural polymer extracted from brown seaweeds. Over the last two decades, alginate fibers have become well established in the wound management industry where their ion exchange and gel forming abilities are particularly useful in the treatment for exuding wounds. Alginate fibers are commonly made by extruding sodium alginate solution into a calcium chloride bath, producing calcium alginate fibers. To improve the gelling ability and the absorption capacity of calcium alginate fibers, this study used hydrochloric acid to convert calcium alginate fibers into alginic acid fibers, which was further converted into sodium alginate fibers by treating the fibers with sodium hydroxide in organic solvent. Results showed that alginic acid and sodium alginate fibers and fabrics can be readily made by treating the calcium alginate fibers and fabrics, respectively, with hydrochloric acid and sodium hydroxide. Improved gel blocking properties and absorption capacities were obtained with the sodium alginate fibers. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 4216–4221, 2006     

Novel type of alginate gel‐based adsorbents for heavy metal removal

Various alginate gel‐based adsorbents were investigated for the removal of heavy metals: alginate beads, alginate capsules, and alginate gel‐coated adsorbent. Of these, alginate capsules showed the greatest Pb²⁺ uptake capacity of 1560 mg g^?1 of dry sodium alginate, and the alginate gel‐coated adsorbent, prepared simply by forming a thin alginate film on an inert matrix, achieved rapid adsorption equilibrium within 10 min. Adsorbed metals were readily removed from the alginate gel‐based adsorbents using eluents such as HNO₃ and could be reused for up to 10 adsorption–desorption cycles without marked loss of metal uptake capacity. Alginate gel‐coated adsorbents could be prepared in a dried state and have great application potential for the removal of heavy metals from contaminated water.

Antibacterial activity of chitosan–alginate sponges incorporating silver sulfadiazine: Effect of ladder‐loop transition of interpolyelectrolyte complex and ionic crosslinking on the antibiotic release

Hydrogel membranes prepared from polyelectrolyte complex (PEC) have been used for repair of wounds and controlled antibacterial release. A simple method, based on homogenizing interpolyelectrolyte complex, has been developed to prepare a chitosan–alginate sponge with high stability. The spongelike chitosan–alginate hydrogel can be used as a wound dressing for the sustained release of silver sulfadiazine (AgSD) in a controlled way. In this study, we evaluated the effect of electrolyteic properties of chitosan and alginate on the characteristics of the prepared chitosan–alginate PEC. All types of the spongelike chitosan–alginate hydrogels exhibited superabsorbent properties. However, only the chitosan–alginate hydrogel prepared by the interpolyelectrolyte complex of alginate with low pH of chitosan, and that prepared by the interpolyelectrolyte complex of chitosan with high pH of alginate, can keep their stability after swelling in PBS solution. FTIR analysis suggests that the protonated amino groups on chitosan and the ionized carboxylic groups on alginate should be responsible for the formation of a stable ladder‐type of chitosan–alginate PEC. Ionic crosslinking is helpful to increase the stability of the loop‐type of chitosan–alginate PEC. The release of AgSD from chitosan–alginate PEC sponges could be controlled by the variation of ladder‐loop structural transition of chitosan–alginate PEC and the ionic crosslinking of the chitosan–alginate complex. The antibacterial ability of AgSD‐incorporated PEC sponges was examined in agar plate against Pseudomonas aeruginosa and Staphylococcus aureus. The result suggests that the PEC sponges containing antimicrobial agents should effectively suppress bacterial proliferation to protect the wound from bacterial invasion. © 2005 Wiley Periodicals, Inc.

Morphology and Property of Calcium Silicate Encapsulated with Alginate Beads

The alginate beads encapsulating calcium silicate were prepared. The morphologies and properties of the encapsulated beads were investigated. The beads were prepared by mixing modified calcium silicate with vinyltriethoxysilane in an alginate solution. The alginate-calcium silicate dispersion was dropped into a calcium chloride solution. The mean particle size of the resulting beads depended on the content of modified calcium silicate in alginate solution. In addition, the shape of the alginate gel was controlled by the viscosity of the alginate solution. The result showed that the calcium silicate particles were well dispersed within the matrix of the alginate. The thermal stability of the alginate beads encapsulating the calcium silicate increased with increasing the content of modified calcium silicate.     

Biosynthesis and characterization of bacteria cellulose–alginate film

A novel polysaccharide membrane containing alginate in bacterial cellulose matrix was synthesized by Acetobacter xylinum under static conditions using a culture medium supplementation with sodium alginate. By increasing alginate content, the bacterial cellulose–alginate (BCA) membrane was more hydrophilic and the film structure became denser with the smaller average pore size. Scanning electron microscope images displayed the deposits of alginate gel on the surfaces of the multilayer cellulose film. The declines in the tensile strength, the Young's modulus, and the elongation at break of the BCA membrane were dependent on the degree of alginate supplement. The BCA membrane showed higher water absorption capacity. The addition of alginate slightly affected the water vapor transmission rate but remarkably decreased the oxygen transmission rate of the membrane. © 2009 Wiley Periodicals, Inc.
