Description
20-25 С в течение 12 ч. Затем на поверхность резистинного сло методом окунани нанос т защитное покрытие в виде смеси 36-42 мас.% ацетонформальдегидной смолы, 2-4 мас.% 35%-ного водного раствора едкого jiaTpa и 54-62 мас.% дистиллированной воды при температуре 20-25 С и в адерживают подложки при этой температуре в течение 6 ч. Далее осуществл ют повторную сушку подложек в сушильном шкафу при температуре ТО-вО С в течение 10-12 ч.20–25 ° C for 12 hours. Then a protective coating is applied to the surface of the resistin layer by dipping in the form of a mixture of 36–42 wt.% Acetone-formaldehyde resin, 2–4 wt.% 35% aqueous caustic jiaTpa and 54-62. wt.% distilled water at a temperature of 20-25 ° C and keep the substrate at this temperature for 6 hours. Then, the substrates are re-dried in a drying oven at a temperature of TO-C for 10-12 hours.
Изготавливают резистивные датчики влажности, именидие электрическое сопротивление от (3-4) .10 до (1-2) Юом, температурный коэффициент сопротивлени +0,050 1/град. При этом изменение электрического сопротивлени после воздействи воды составл ет от (3-4) -10 до 8-10 Ом в течение 1 ч и от (1-2). 10 до 210 Ом в течение суток. Влагочувствительные резисторы характеризуютс малым разбросом электрического сопротивлени , посто нным температурным коэффициентом сопротивлени и незначительным плавным изменением электрического сопротивлени при воздействии влаги в течение суток.Resistive humidity sensors are made, the electrical resistance is from (3-4) .10 to (1-2) Yu, the temperature coefficient of resistance is +0.050 1 / deg. The change in electrical resistance after exposure to water is from (3-4) -10 to 8-10 ohms for 1 hour and from (1-2). 10 to 210 ohms during the day. Moisture-sensitive resistors are characterized by a small variation in electrical resistance, a constant temperature coefficient of resistance and a slight smooth change in electrical resistance when exposed to moisture during the day.
Изобретение позвол ет повысить влагочувствительность резистивных датчиков влажности, стабильность их электрических характеристик и обеспечивает-возможность изготовлени влагочувствительных резисторов с быстрой или замедленной чувствительностью к воздействию проникающей влаги.The invention improves the moisture sensitivity of resistive humidity sensors, the stability of their electrical characteristics and provides the ability to manufacture moisture sensitive resistors with fast or slowed sensitivity to the effects of penetrating moisture.
