PRODUCT DATA SHEETDATE OF ISSUE: NOVEMBER 2015 VERSION: 001610/12.0ATLAC® 580CHEMICAL/PHYSICAL NATUREAtlac ®580 is a high-grade bisphenol A vinyl esterurethane resin, which combines exceptional chemical resistance and an outstanding combination of heatresistance and flexibility. Furthermore Atlac ®580 has very good handling and curing properties. Atlac ® 580 is resistant to many aqueous acidic salts and alkalinesolutions. Especially against alkaline media and hot waterAtlac ®580 has an outstanding performance. MAJOR APPLICATIONSAtlac ® 580 can be used in all fabrication methods, but is especially adapted to meet the requirements of filament winding, centrifugal casting and spray-up applications. Extra additional of styrene leads to viscosities which are needed for resin injection molding techniques. PRINCIPAL PROPERTIESAtlac 580 has excellent wet-out and deaeratingproperties. It produces less foam when peroxides are added with less air inhibition, resulting in a tack free cured surface.Due to its urethane incorporation, Atlac 580 can be thixotropized easily and shows an improvedcompatibility with aramid fiber reinforcements. Atlac 580 has a low exotherm in curing allowing thick sections to be fabricated.PRODUCT SPECIFICATIONS UPON DELIVERYREMARKSTM 2013:Cond. 23° Physica, sp Z2, 100s-1TM 2625: 2,5g NL49P + 1,0g Pergaquick A2 X + 1,0g Butanox M50PROPERTIES OF THE LIQUID RESIN (TYPICAL VALUES)PROPERTIES OF CAST UNFILLED RESIN (TYPICAL VALUES)PROPERTIES OF CAST FILLED RESIN (TYPICAL VALUES)CURING CONDITIONSAll properties are measured at 20°C unless otherwise specified.

Stir the product before blending.STORAGE GUIDELINESThe resin should be stored indoors in the original, unopened and undamaged packaging, in a dry place at temperatures between 5°C and 30°C and the properties might change during storage. Shelf life is reduced at higher temperatures and the properties of the resin might change during storage. The shelf life of styrene containing unsaturated polyesters will be significantly reduced when exposed to light. Store in dark and in 100%light tight containers only.SHELF LIFE AND RETESTING PERIODUnder the above mentioned storage conditions the shelf life and retesting period of the resin will be 6 months ex works.

TCA785中文资料ＴＣＡ７８５是德国西门子（Ｓｉｅｍｅｎｓ）公司开发的第三代晶闸管单片移相触发集成电路，与其它芯片相比，ＴＣＡ７８５具有温度适用范围宽，对过零点的识别更加可靠，输出脉冲的整齐度更好，移相范围更宽等优点。
另外，由于它输出脉冲的宽度可手动自由调节，所以适用范围更为广泛。
ＴＣＡ７８５的基本引脚波形如图１所示。
其中５脚为外接同步信号端，用于检测交流电压过零点。
１０脚为片内产生的同步锯齿波，其斜坡最大及最小值由９、１０两脚的外接电阻与电容决定。
通过与１１脚的控制电压相比较，在１５和１４脚可输出同步的脉冲信号，因此，改变１１脚的控制电压，就可以实现移相控制，脉冲的宽度则由１２脚外接电容值决定[1]，当选择双窄脉冲的驱动方式时，１２脚应接１５０ｐＦ电容。
实际上，有几十个微秒的脉冲宽度即可使晶闸管正常导通。
３使用ＴＣＡ７８５实现相控整流实现三相桥式相控整流的一般方法是利用三相同步变压器从电源进线端引入三路同步信号，这样，将同步信号整形后分别输到三片ＴＣＡ７８５（编号为Ａ、Ｂ、Ｃ）的５脚，就能控制６只晶闸管，然后通过引脚复用即可实现双窄脉冲方式驱动。
双窄脉冲方式由于驱动脉宽窄，因而可以有效地减小驱动用脉冲变压器的体积，防止磁芯饱和[２]。
该方法的主电路及同步变压器如图２所示，三片ＴＣＡ７８５芯片的引脚与所控制的晶闸管的对应关系如表１所列。
晶闸管通过一个△／Ｙ型同步变压器为ＴＣＡ７８５提供同步信号，当进线相序（如图２所示）为正序Ａ、Ｂ、Ｃ时，同步变压器的三个输出端所对应的中性点的实际电压向量为ＡＣ、ＢＡ、ＣＢ，将ＡＣ接至ＴＣＡ７８５（Ａ），ＢＡ接至ＴＣＡ７８５（Ｂ），ＣＢ接至ＴＣＡ７８５（Ｃ），即可实现正序输入时晶闸管的同步驱动。
现以Ｔ５～Ｔ１换流为例进行分析：Ｔ５至Ｔ１管自然换流点滞后于Ａ相由负到正过零点３０°，即ＴＣＡ７８５（Ａ）的１５脚输出至少应该滞后于该过零点３０°，而电压ＡＣ由负到正过零点正好滞后于Ａ相３０°，因而用ＡＣ作为ＴＣＡ７８５（Ａ）的同步信号就可以实现最大范围的移相控制[３]。
