SKYELEC Heater Rod Thermostats are suitable for use with Single Phase to control heating in electroplating baths.They are equipped with a 1.6 metre supply cord and standard red cap terminal casing.
The temperature control probe is suitable for automatic control of a pre-set value in the process media and are suitable for heaters up to 2.3 kw single phase. For higher loads, or three phase heaters an additional contactor should be used.
The probes construction makes it ideally suited for etch, pickle and plating solutions. Its robust construction and chemical resistance ensures a long service life. To set the rod thermostat, unscrew the red cover which provides access to the temperature setting control knob. Turn until the desired temperature is opposite the arrow.
Suitable for use with single phase to control heating of electroplating baths and similar solutions.

The Fangshan talc production area is mainly in the Huangshan store area west of Zhoukoudian. Among them, Huangshan Store is the most concentrated, and there are also places in Minli Water, Huangyuan Temple and Simapou. According to the survey of the original small mining area in the spring of 1955: the talc resources of Huangshandian Village are distributed in two places. The first is the north of the village, which is centered on the north of the mountain. It extends about 2 mile to the southwest and connects to the ecliptic to the east. It stretches for more than ten miles. Contains. The other is centered on the Huangdaogou. It is about 15 miles eastward, about 5 miles south, and about 5 miles north. It is very rich in reserves. The talc of the Lili Water Village is hidden in the east of the village, and it is about 3 miles east of the city, about 1.5 miles to the west, and about 8 miles to the south. The talc of Huangyuansi Village is distributed in Xiaozhangou, about 5 miles eastward and about 1 mile north. There are also treasures in Si Magou.
Fangshan talc was discovered as early as the early 1920s. In the early years of the Republic of China, in the process of compiling China's first geological specialty book, "Xishan Geology", Chinese and foreign geologists had conducted extensive investigations on Fangshan Geology. In the 1930s, Zhao Kuan, the owner of Huangshan Store Mountain, invested in talc mining and employed more than 10 people. They dig one year and produce about 200 tons. It is sold in Beiping City and is mainly used in the cosmetics industry to make cool materials and make powder, powder and hazelnut powder. After the Japanese invading army occupied Fangshan in 1937, it investigated the mineral resources of Fangshan, especially the geological concern of the Longgushan area. At the time, there was a Japanese businessman, Yujing, who was stationed in Zhoukoudian, and found talc. He made a purchase at Zhoukoudian. Yujing bought 200 tons of talc from the hands of Zhao Kuan, the owner of Huangshan Store Mountain, and resold Beiping. At that time, the production of Fangshan talc could only be stopped at the time of production, and the scale of production could not be expanded. On the eve of New China, talc production has been dying.
After the founding of New China, vigorously carry out sideline production and mobilize farmers to find mines and mine. Fangshan talc production began to expand.äº’åˆ©æ°´æ‘ and Huangyuansi Village have successively established mutual aid groups to carry out talc production. At that time, 129 ton of talc was produced in the village of Kenli, and 60 tons of talc was produced in Huangyuansi Village. Delivered in the village, the price can be 12-13 yuan per ton, the user is the chemical plant in Beijing, and the factory organizes the acquisition and transportation. However, due to the soft texture of the talc and the low oiliness, the two plots were discontinued in 1951. In 1951, the Huangshandian people also organized production cooperatives to produce talc again. The output of the year was 50 tons and was shipped to the chemical plant in Beijing. The price per ton reached 132.50 yuan. In 1952, the annual output of talc reached 500 tons, 28.50 yuan per ton.
In August of the same year, most of the western mountainous areas of Fangshan were included in the Jingxi mining area. Special attention is paid to the development of mining resources, and the Minerals Section is set up to manage the mining industry to help guide production and sales. In 1953, the mining government set up an industrial and agricultural production service sales office to promote the Jingxi minerals, opening up new users for talc. At that time, the output of talc in Huangshan Store soared to 700 tons and was shipped to the factory at a price of 27.30 yuan per ton. In 1954, the government of Beijing West Mining District launched a mutual cooperation and cooperation campaign for agricultural production, established a talc production agency in Huangshan Store, increased the investment in talc production, and included the development of talc in the development plan, which was clearly promoted by the production cooperatives of Jingxi Mining Area. The Zhoukoudian office is responsible for operating sales. At that time, the production of talc in Huangshan Store leaped to 6,200 tons and sold 5,940 tons. From the place of origin to the Zhoukoudian Railway Station, it is transported by manpower and carriage. Delivery from Zhoukoudian Railway Station to the factory, the price per ton is about 20 yuan. The main users of the products are the state-owned Huabei Zhengzhou Pharmaceutical Factory and the chemical plants in Beijing and Tianjin. 90% of talc sales are for state-owned factories, and another 10% are for privately owned factories. In November 1954, Kenli Water and Huangyuan Temple also organized the establishment of agricultural production and handicraft production cooperatives, which restored the talc production that had been stopped for three years. At that time, 103 tons of water-producing talc and 30 tons of talc produced by Huangyuan Temple were delivered to Zhoukoudian Railway Station and sold by Zhoukoudian Office of the production and marketing department of the mining area. By the beginning of 1955, Fangshan talc production was distributed in the three villages of Huangshandian, Kenli Water and Huangyuan Temple.
By 1955, the production methods of Fangshan talc were all artificially mined by soil. The production process is eye-catching - shooting - pillars - carrying out the mine hole - dumping the yard - processing crushing and screening - bagging - shipped out of sales. The products are divided into green white, pure white and black white. Green and white, pure white blocky and soft, the top grade, black and white with stone heart (such as limestone , black stone, tartar, white stone, etc.) as a defective product. The talc produced by Fangshan usually accounts for 10% of green and white, 30% of pure white, and 60% of black and white. The green-white talc is mostly produced in Huangshandian. The pure white is mostly produced in the water, and the black-white is in the three places. When bagging out, the bag is mixed and bagged. The bag is responsible for the buyer. It is usually a single-layer sack, each bag weighing 100 kg. With the development of industry, talc has been widely used in papermaking and rubber industries in China. Chinese medicine is used to treat diseases such as heat-clearing, dampness, urinary rash, heat, polydipsia, and diuresis. The talcum powder and hazelnut powder in the cosmetics industry have used talc as the main raw material.
All the talc production mines in Fangshan are seasonally produced. From July to August, due to the large stoppage of the mine water, the rain has gradually decreased in September, but the agriculture is busy producing only half a month. In 1956, the state adjusted the mineral resources policy, the collective mining production units were merged into the state-run, and the private mining kiln was closed. In 1958, the government of Jingxi Mining Area was cancelled, and the production of Fangshan talc stopped.

Fangshan talc mining
Fangshan is rich in mineral resources and a wide variety, and talc is one of them. Talc, metamorphic rock is usually made of magnesium-containing, is monoclinic, often flaky, scaly or dense block assemblies. The color is mostly green or white, like glass luster.
