  China will further bolster its small and micro businesses with financial measures to increase economic vitality, the State Council executive meeting, chaired by Premier Li Keqiang, decided on Wednesday.

  In order to boost policy support and encourage financial institutions to step up financial services, the credit ceiling of the value added tax exemption for interest derived from bank loans to small and micro businesses, farmers and self-employed will be expanded from 100,000 yuan to 1 million yuan (US$15,075 to US$150,750) between Dec 1, 2017, and Dec 31, 2019.

  The stamp tax exemption for borrowing contracts of small and micro businesses and the VAT exemption for those with a monthly sales volume of less than 30,000 yuan will be extended through 2020.

  More efforts will be made to put inclusive finance service offices of State-owned banks in place at the grassroots level. Commercial banks will enjoy a cut in the required reserve ratio if their total or percentage of increase reaches a certain standard for individual loans of less than 5 million yuan to small and micro businesses, farmers, people under the poverty line, students and guaranteed loans for startups.

  "Small and micro businesses have been a strong pillar for employment, offering strong support for large and medium-sized enterprises, and increased vitality for the society," Li said. "We should encourage financial institutions to lower their footing and strengthen capacities to serve the real economy."

  He added, "Financial resources should flow more to the real economy, especially to agriculture and small and micro businesses, to ease their credit crunch and high financing cost."

  Such businesses have played a pivotal role in creating new jobs, as each small and micro enterprise can help create eight new jobs and each self-employed business creates 2.8 jobs on average, according to the National Bureau of Statistics.

  The State Council, China’s Cabinet, also decided at the executive meeting that the government will make greater efforts to develop governmental financing guarantee and re-guarantee insti tutions, with a national financing guarantee fund also in the pipeline. Venture capital funds will be encouraged to devote more investment to small businesses in their early periods.

  "The development of inclusive finance should be a priority so small and micro businesses and other weaker links can receive consistent support. The fin ancing of small and micro businesses is a global challenge. But it is of major importance, and should be highly prioritized," Li said.

  "We managed to make some progress over the years, reaching targets in the growth rate of bank lending to small and micro businesses no lower than lending across the board, the number of individual loans and the rate for loan approval no lower than the same period last year. Such measures have increased SME chance of survival," he said.

  Policies for small and micro businesses should cover self-employed businesses and farmers as well to increase policy effectiveness, he added.

Many of these snap action thermostat options are available as in stock standard products and are ready to ship. Browse our inventory below or visit our Thermostat Design Configurator to find the right Snap Disc thermostat for your project!

  

  Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” f rom a convex to a concave shape at a set temperature. When the disc “snaps”, it either completes or interrupts a circuit. Snap Disc thermostats have many practical applications. They are used in both heating and cooling applicat ions to ensure the process temperatures do not exceed the thermal limits of the equipment or process. In some cases, Snap Disc thermostats with tight differential models can be used as the primary temperature control device. However, the most common application for a snap switch or snap action thermostat is as an over-temperature protection (or OTP) failsafe.

  Because of their small size and low mass, the response time of the snap switch design is extremely rapid compared to other commercially available thermostatic devices. Additionally, the bimetal element of a Snap Disc does not carry the current, but acts as the force to open and close the contacts. Thus snap action thermostats have a long life at relatively high currents – up to 16 amps for the ? inch series – making snap switches the first choice of many OEMs.

  Precision Snap Disc thermostats are found in commercial food equipment, adhesive dispensing devices, laboratory instrumentation, aircrafts, medical equipment, electronic control systems and more. Commercial Snap Disc thermostats are most commonly found in appliances, heat and smoke detectors and HVAC equipment.

  Comstat offers the following standard types of these bimetal snap switch thermostats: automatic reset Snap Disc thermostats; manual reset Snap Disc thermostats, and adjustable Snap Disc thermostats. Comstat also offers the widest possible operating temperature ranges for bimetal thermostats, ranging from -45C to +425C.

Resistors/heaters are not simple.

  

  The inrush to a heater depends on how hot it gets, and the temperature coefficient of the material.

  For a resistor with a nominally zero tempco, so component resistors, or resistors made from specialist resistance alloys, there will be essentially no inrush.

  For a filament lamp, the resistor runs hot, and the tungsten filament has a strong tempco. You can expect an inrush of up to 10x running current when they are first turned on.

  There are other heater types between these two extremes. Single metals will tend to have a small tempco in the 0.5% to 1% per degree region, which will result in a tiny inrush, probably much less than 2x. Quartz tube radiant heaters do not run quite as hot as filament light bulbs, and tend to use an alloy rather than tungsten, so could be anywhere in the none to 10x inrush range.

  You have to find out, for your proposed heaters, how hot the heater wire itself is going to run, and what material it’s made from. Or just measure the inrush.

BMC is an acronym for Bulk Molding Compound. Since it is usually mixed in a dough-like form, rather than as a sheet, BMC is also called DMC. It is made of resins (such as unsaturated polyesters, epoxy resins, phenolic resins, etc.), glass fibres, fillers and other additives. It can be adjusted by changing the added material according to the required properties. It is usually made into stripes to facilitate moulding and is widely used in many industrial fields.

  

  BMC and SMC(sheet molding compound) are similar in composition. But for BMC moulding, firstly, it should be mixed the polyester resin and additives. After this step, it becomes a resin mixture, and then adds the filler. Next, reduce the mixing speed of the "premix" to prevent the glass fiber from cracking. If the material needs to be further concentrated, a thickener should be added. This material can be used for compression moulding and injection moulding.

  The development history: In the early 1960s, BMC materials were developed by British BIP Company and American R&H Company with low shrinkage and non-shrinkage BMC, which greatly improved the dimensional stability, smoothness and appearance of the material. Polyester moulded plastic. In the 1970s, applications requiring dimensional accuracy, high rigidity and heat resistance, such as office machine stand. In the mid-1980s, to expand the range of applications, freely colourable BMCs were developed.

  Proportionally, the BMC material is mainly composed of three parts. It consists of matrix resin – unsaturated polyester resin and low shrinkage system, reinforcing material – mainly glass fibre, filler – calcium carbonate, talc, aluminium hydroxide, china clay, etc. Although the amount of these components account for a small proportion of the total components, they play a very special role in the formulation system of BMC. They will have an important impact on the preparation process, product moulding and final properties of BMC.
