作者简介：赵明德（1969-），男，助理工程师，主要从事橡胶输送带的研发和管理。
收稿日期：2023-08-28我国是钢铁生产大国，在烧结矿、焦炭等高温物料输送过程中，经过处理后大部分物料的温度在300 ℃以下，但仍有小部分物料温度较高，甚至出现明火现象。
为保证生产的安全和使用寿命，不仅要求输送带既耐高温，又要具有一定的阻燃性能。
输送带的耐高温阻燃性能主要取决于覆盖胶的性能，为此，我们研制了耐高温阻燃输送带覆盖胶。
覆盖胶的耐热性能达到了GB/T20021—2017中T4级别的要求，阻燃性能达到了GB/T10822—2014标准中K2级别要求。
本文详细阐述了研制过程。

固体氯化石蜡70、十溴二苯醚、十溴二苯乙烷等均为市售材料。
1.2 主要仪器和检测设备DLL -5000N 拉力试验机，MDR -2000无转子硫化仪，均为上海德杰仪器设备有限公司产品。
GT -7017高温老化试验箱、滚筒磨耗试验机均为高铁检测仪器有限公司产品。
2 耐高温阻燃覆盖胶配方的研制2.1 胶种的选择我们都知道，橡胶所谓的耐热性就是在高温长时耐高温阻燃输送带覆盖胶的研制赵明德(山东一诺胶带有限公司，山东 潍坊 262600)摘要：介绍了耐高温阻燃输送带覆盖胶的研制，经优化组合最终确定覆盖胶配方为：乙丙胶CO054/S537-3 70/30，炭黑N220 50，Sunpar 2280/HY209树脂20，阻燃剂十溴二苯乙烷/三氧化二锑/硼酸锌 16/8/7，过氧化二异丙苯/TAIC 6，防老剂MB/MC445 4。
采用该配方生产的输送带耐热性能达到了GB/T20021—2017中T4级别要求，阻燃性能达到了GB/T10822标准K2级别要求。

ADC121C021/ADC121C021Q/ADC121C027 I2C-Compatible, 12-Bit Analog-to-Digital Converter with Alert FunctionGeneral DescriptionThese converters are low-power, monolithic, 12-bit, analog-to-digital converters (ADCs) that operates from a +2.7 to 5.5V supply. The converter is based upon a successive approxi-mation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz. These converters operate from a single supply which also serves as the reference. The device features an I2C-compatible serial interface that operates in all three speed modes, including high speed mode (3.4MHz).The ADC121C021's Alert feature provides an interrupt that is activated when the analog input violates a programmable up-per or lower limit value. The device features an automatic conversion mode, which frees up the controller and I2C inter-face. In this mode, the ADC continuously monitors the analog input for an "out-of-range" condition and provides an interrupt if the measured voltage goes out-of-range.The ADC121C021 comes in two packages: a small TSOT-6 package with an alert output, and an MSOP-8 package with an alert output and two address selection inputs. The ADC121C021Q is available in TSOT-6 package. The ADC121C027 comes in a small TSOT-6 package with an ad-dress selection input. The ADC121C027 provides three pin-selectable addresses while the MSOP-8 version of the ADC121C021 provides nine pin-selectable addresses. Pin-compatible alternatives to the TSOT-6 options are available with additional address options.Normal power consumption using a +3V or +5V supply is 0.26mW or 0.78mW, respectively. The automatic power-down feature reduces the power consumption to less than 1µW while not converting. Operation over the industrial tem-perature range of −40°C to +105°C is guaranteed. Their low power consumption and small packages make this family of ADCs an excellent choice for use in battery operated equip-ment.The ADC121C021 and ADC121C027 are part of a family of pin-compatible ADCs that also provide 8 and 10 bit resolution. For 8-bit ADCs see the ADC081C021 and ADC081C027. For 10-bit ADCs see the ADC101C021 and ADC101C027.Features●I2C-Compatible 2-wire Interface which supports standard(100kHz), fast (400kHz), and high speed (3.4MHz) modes ●Extended power supply range (+2.7V to +5.5V)●Up to nine pin-selectable chip addresses (MSOP-8 only)●Out-of-range Alert Function●Automatic Power-down mode while not converting●Very small TSOT-6 and MSOP-8 packages●ADC121C021Q is an Automotive Grade product that isAEC-Q100 grade 2 qualified.Key Specifications●Resolution12 bits; no missing codes ●Conversion Time1µs (typ)●INL & DNL±1 LSB (max) (up to 22ksps)●Throughput Rate188.9ksps (max)●Power Consumption (at 22ksps)—3V Supply0.26 mW (typ)—5V Supply0.78 mW (typ) Applications●System Monitoring●Peak Detection●Portable Instruments●Medical Instruments●Test Equipment●AutomotivePin-Compatible AlternativesAll devices are fully pin and function compatible across reso-lution.Resolution TSOT-6 (Alert only)and MSOP-8TSOT-6 (Addr only) 12-bit ADC121C021ADC121C02710-bit ADC101C021ADC101C0278-bit ADC081C021ADC081C027I2C® is a registered trademark of Phillips Corporation.PRODUCTION DATA information is current as ofpublication date.
