The company dynamic

Dongguan hua yu electric products co., LTD. Is a and heating, hair hotline, production and r&d of electric heating products manufacturer, the company production of various fever piece, hair hotline. Ceramic heat is only one of them, to introduce you to what is under the ceramic heating.

 

A, the phonological features of ceramic heat:

 

High temperature baking ceramic heating tablets (MCH) is printed directly on the AL2O3 alumina ceramic green resistance paste, under the high temperature of 1600 ℃ baking to burn, and then after electrodes, wire processing, the production of a new generation of low temperature heating element. Is the alloy heating wire, PTC heating elements after another generation product, widely used in daily life, industrial and agricultural technology, communications, medical, environmental protection, such as the need of low temperature heat in many fields. In terms of household electric appliances, such as small low dimming device, hair dryer, clothes dryer, heating machine, warm and cool cell phone, dryer, electric heating plate, iron, electric, straight hair, curly hair hair curler, electric vacuum flask, heat preservation tank, electric cooker, ceramic heaters, water heaters, etc.; In industry, such as industrial drying equipment, electric heating bonding machine, water and oil and acid and alkali liquid heater, etc.; In the electronic industry such as small special crystal device thermostat; Such as infrared fields in medical treatment, intravenous fluids heater and so on.

Background information:

 

With the advent of the era of various electronic devices integration, electronic machine of circuit miniaturization, high density, versatility, high reliability, high speed and high power put forward higher request, because the co-firing multilayer ceramic substrate can satisfy the demands of electronic machine of circuit, so obtained widespread application in recent years. Co-firing multilayer ceramic substrate can be divided into high temperature co-firing multilayer ceramic substrate (HTCC) and low temperature co-firing multilayer ceramic (LTCC) substrate. Temperature co-firing ceramic with low temperature co-firing ceramic compared with the high density of high mechanical strength, wiring, stable chemical performance, high coefficient of heat transfer and low material cost, higher request on thermal stability, high temperature volatile gas demands a smaller, sealing, higher heating and assembly field more widely used. HTCC ceramics fever piece mainly alternative is now the most widely used alloy wire electric heating element and the PTC heating element and its components. Wire electric heating element is easily oxidized in high temperature and short service life, open flames unsafe, thermal efficiency is low, such as uneven heating shortcoming; And the heating temperature of PTC heating element is normally about 200 ℃, the heating temperature is higher than 120 ℃ is generally used red lead, because big and are being phased out belongs to the product.
