耐高溫雲母板發熱絲的幾個安全問題
Several safety problems of 耐高溫雲母板發熱絲
1. Because the heating wire adopts the adhesive process, the metal heating wire and the high temperature resistant mica board have different expansion coefficients after heating, and they are simply layered. Together, the glue volatilizes under the high temperature state and will simply fall in the future. The heating wire is interlaced and simply short-circuited. . The product is completely mechanically connected, with no glue technology, high temperature resistance, not easy to fall, and safe.
2. The local current of the heating wire in the corner is too large, and the temperature can reach 500-700 degrees. risk. The product is surface-like heating, uniform temperature, and not easy to melt.
3、由於電熱絲為直線加熱,難以保證加熱的均勻性。 電熱絲表面溫度達到500度。 因此,電熱絲雲母加熱板會在高溫雲母板表面烘烤一段時間後。 黑色的印像很漂亮。 如果外部雲母長時間暴露在這種高溫下,會影響雲母基材的使用壽命。
4、在極端安全的情況下,電熱絲會先在雲母層燒出一個大孔,一直以超額定功率通電加熱,直到電熱絲完全燒斷。 此過程可能會點燃木地板、地毯和其他易燃材料。 在極端條件下,如使用異常電壓,電熱膜雲母發熱板會親自斷開,導致功率下降,或發熱體自毀不再發熱,不會引起火災和其他風險。
5、雲母加熱板採用串聯電路設計。 如有一點損壞,則整個電加熱器報廢,產品採用全並聯電路設計。 如果表現出極端條件,即使是熱件損壞,消費者也感受不到對其他熱件操作的影響。 從幾年的商場來看,電熱膜廠家的返修率只有0.2%。
6. The mica heating plate has a large starting current, usually 3-4 times the rated current. It also heats up in the junction box. Therefore, the electric heating plate simply presents the appearance of firing and firing in the outlet box, even in the products of some supporting manufacturers. It presents the appearance of a big black hole burning at the junction box. The starting current of the product is small, usually about 0.8 times the rated current, the current is stable, and the leakage current is usually less than 0.025mA.
7.由於電熱絲特殊的上膠工藝,膠水在高溫下會變成粉末並聞到一股難聞的氣味,且氣味經檢測富含甲醛,產品為完全無膠工藝,無味又環保。 有SGS環保聲明。
