กระจกห้องน้ำอัจฉริยะ: การพัฒนาและประวัติของกระจก

ผู้คนสามารถแยกแยะการสะท้อนตนเองตั้งแต่สมัยโบราณ ตอนแรกน้ำถูกใช้เป็น asกระจกเงา. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the กระจกเงา for self-reflecting evolved into a bronze กระจกเงา. The earlier glass กระจกเงาs in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass กระจกเงา has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the กระจกเงา surface is generally narrow and easy to carry; the กระจกเงา is mostly used for shaving and shaving, and the กระจกเงา surface is only enough to shadow the partial beard.Then, with the passage of time, the silver กระจกเงา used by most of us came into being. With the development of technology, the function of the กระจกเงา is only self-reflection, it is more intelligent and more humane. More functional, such as: anti-fog, watch time, measure temperature, watch TV, etc. The material of the กระจกเงา has also been upgraded from a silver กระจกเงา to an "environmental protection กระจกเงา". This กระจกเงา uses lead-free paint, which is a technical breakthrough of silver กระจกเงาs. This kind of กระจกเงา is called a lead-free and copper-free กระจกเงา, also known as an "environmental protection กระจกเงา.
