Abstract: A method for analyzing polycarbonate(PC) and polybutylene terephthalate(PBT) quantitatively in PC/PBT materials is provided to allow effective and accurate quantitative analysis and therefore to utilize efficiently in development or benchmarking of a product, or in response to problems caused by the quality. A method for quantitatively analyzing polycarbonate and polybutylene terephthalate respectively in polycarbonate(PC)/polybutylene terephthalate(PBT) blend materials comprises the steps of: preparing a sample for a temperature gravimetric analyzer(TGA) by using polycarbonate(PC)/polybutylene terephthalate(PBT) blend materials; raising a temperature of the sample from an elevated temperature of 30 deg.C to 650 deg.C at an elevating rate of 20 deg.C/min in a nitrogen atmosphere by using the TGA, followed by raising the temperature to 800 deg.C at an elevating rate of 20 deg.C/min in an oxygen atmosphere; and calculating a respective content of polycarbonate and polybutylene terephthalate from a formula(1) and a formula(2) by using a result of TGA. In the formula(1), the content of polycarbonate(PC) = A + (26.8/73.2) x A and in the formula(2), the content of polybutylene terephthalate(PBT) = B + (2.9/97.1) x B, wherein A is PC heat loss amount from an inflection point of a differential curve to 650 deg.C in a TGA graph and B is PBT heat loss amount to an inflection point of a differential curve in a TGA graph.

Abstract: 본고안은윈드쉴드와이퍼스톱위치(P)에열선(6)을프린트함으로써단순한스위치조작에의해겨울철비나눈에의해빙결된와이퍼를녹일수 있도록한 와이퍼빙결해소용열선장치에관한것이다. 종래의와이퍼는빙결된상태에서작동을시키는경우와이퍼블레이드(2)의손상및 무리한고속회전으로인한와이퍼모터의소손이우려되었고, 난방장치의디프로스터및 드포그로스터모드로하는경우도시간이걸릴뿐 아니라그 효과면에서도미미했었다. 이에본 고안은와이퍼스톱위치(P)에열선(6)을다수개설치하고스위치(9)로이를작동시켜열선(6)의저항에의해발생한열이빙결된와이퍼를녹일수 있도록하였다. 또한타이머로작동하게하여별도로오프스위치를누르지않아도되며, 외부에서보았을때 코팅에의해가려지고차량내부에서보았을때는크래쉬패드(7)에가려지도록하여외관상의미적효과를꾀하였다.
