In addition, FTIR spectrum of PVA nanofiber is shown inQt4-20 AAC Brick Block Making Machine Price Nepal. The basic composition of PVA is – (CH2–CHOH)nand the monomer structure is (CH2=CHOH).Pressure Accelerated Aging Test Chamber (HAST)clearly reveals the major peaks associated with PVA. The peak observed at approximately 1100 cm–1Fan Coil Unit Central Air Conditioning Cooling System Chiller Industrial Air Cooler–1indicates the –C = O carbonyl stretching bond. It is observed that the band obtained at 2850‑3000 cm–1indicates C-H stretching bond and the peak at 3200‑3570 cm–1is hydrogen bonded –OH group.
