PVA and PVP Hydrogel Blends for Wound Dressing: Synthesis and Characterisation Mureşan-Pop Marieta1,a, Klara Magyari1,b, and Adriana Vulpoi1,c* 1Nanostructured Materials and Bio-Nano-Interfaces Center, Interdisciplinary Research Institute on Bio-Nano-Sciences, Babes-Bolyai University, Cluj-Napoca, Romania amarieta.muresan@phys.ubbcluj.ro, bklara.magyari@ubbcluj.ro, cadriana.vulpoi@phys.ubbcluj.ro Keywords: hydrogel, poly(vinyl alcohol), poly(vinyl pyrolidone), hydrogen bonding.
Hydrogels have an important role in wound dressing or tissue repair; they are defined as macromolecular systems, able to incorporate an aqueous medium, but which retain their shape; are formed of a (2-80%) polymeric material, and (20-98%) water.
PVA is one of the most appreciated synthetic polymer, due to the hydroxyl group in its structure, showing a high biocompatibility in biomedical applications, accepted as biomaterial since 1977 [3, 4], and continues to be used in artificial cartilage implants or wounds dressings [5, 6, 7, 8], as a substitute for blood plasma, to achieve suture wires, or as material in the manufacture of contact lenses [9].
Materials and Methods Hydrogel preparation: For synthesis of the hydrogels, two polymeric solutions (5% w/v) were prepared by dissolving the dry polymers in bidistilled water.

The computer simulation technology can be used to partly replace the laboratory experiment, and effective save labor power, material and financial resources Due to the modeling, analysis, modification and test of simulation experiments are performed on computer, so the processes are quick and effective [2,3].
According to reference, working-screw’s materials are 20CrMo whose tensile strength is σb≥885MPa and yield strength is σs≥685MPa.
The maximum stress in working-screw is far less than the material’s strength limits at two kinds of working gear ratios.

The temperature control and crack prevention measures which target the causes of cracks include: in the quality of raw materials, optimizing the mixing ratio of concrete through experiment, adding a suitable amount of fly ash, using additives to reduce the dosage of cement and lowering the rise in temperature caused by concrete hydration heat and the shrinkage of autogenous volume.

The rate of cracking is high due to the early temperature difference inside and outside, and the later temperature drop shrinkage; Selecting the best raw materials for concrete and surface heat preservation is an effective way to prevent cracks on the inverted T-type gate pier structure.
