Chemlok 402X 产品说明说明书
Chemlok® 402X Technical Data SheetChemlok® 402X is a solvent-based, one-coat surface treatment for affixing textiles to a wide variety of unvulcanized elastomers. Chemlok 402X is an all-xylene version of Chemlok 402. It is composed of a mixture of polymers, organic compounds and fillers dissolved or dispersed in an organic solvent system.Chemlok 402X is used in the production of hoses, belts, diaphragms and other textile-reinforced rubber products. It can also be used as an additive to tie cements, as a replacement for isocyanates that are widely used in rubber/ textile bonding.Features and Benefits:Versatile – affixes a variety of elastomers to a wide variety of textiles, including polyester, polyamide, cotton, rayon, and polyaramid.Non-chlorinated Solvent System – suitable for solvent incineration, saving cost of recovery equipment. Excellent Performance – works well on RFL-treated fabric or cord. Fabric or cord treated with Chemlok 402X can be used in process once Chemlok 402X film is tack-free.Convenient – requires only a single coat for most applications, reducing labor, solvent usage, inventory and shipping costs.Elastomers:• Natural Rubber (NR) • Polychloroprene (CR)• Polyisoprene (IR) • Nitrile (NBR)• Styrene-butadiene (SBR) • Butyl (IIR)• Polybutadiene (BR)Application:Mixing – Thoroughly stir Chemlok 402X before use, and agitate sufficiently during use to keep dispersed solids uniformly suspended. If dilution is needed, use xylene or toluene. Note proper dilution for the various application methods is best achieved by experience. Give careful attention to agitation since dilution will accelerate settling. Applying – Apply Chemlok 402X by dip, brush or spray methods. For most applications, 6-10% dry weight pickup is necessary. To optimize both performance and flexibility, apply Chemlok 402X to the fabric at a level just high enough to meet performance specifications.For affixing specialty elastomers such as EPDM and epichlorohydrin, Chemlok 402X should be topcoated with another specialty covercoat designed for that specific elastomer. Using this method helps ensure strong cohesive strength of the system.Drying/Curing – Allow Chemlok 402X to dry until the coated fabric is tack-free and visual examination of the film has shown that all solvent has evaporated. This will take approximately 30-60 minutes at room temperature. Drying time can be shortened by oven drying for 10-15 minutesat 65°C (150°F). Higher temperatures may be used to reduce drying times, but care must be taken to ensure that excessive heat does not cause adverse effects. Shelf Life/Storage:Shelf life is nine months from date of shipment when stored by the recipient in a well ventilated area at 21-27°C (70-80°F) in original, unopened container. Do not store container outside.Chemlok 402X is moisture sensitive.

40度是国标的标延基准温度
40度是国标的标延基准温度英文回答：In the standard of GB/T 13005-2021 "Standard value of atmospheric pressure and temperature for the calibration of liquid volume measuring instruments", 40°C is specified as the standard reference temperature for the calibration of liquid volume measuring instruments.The calibration of liquid volume measuring instruments is based on the principle of volume expansion and contraction with temperature. When the temperature of the liquid changes, its volume will also change. Therefore, in order to ensure the accuracy of the calibration, it is necessary to specify a fixed temperature as the standard reference temperature.The standard reference temperature of 40°C is selected because it is close to the average temperature of liquid volume measuring instruments in actual use. In addition,40°C is also a relatively stable temperature, which can effectively reduce the influence of temperature changes on the calibration results.中文回答：按照GB/T 13005-2021《液体计量器具校准用大气压力和温度标准值》规定，40°C为液体计量器具校准用的标准参考温度。

The control device featuring the generic PDS interface controls the drive devices via the communication network.The network technology may provide different communication services for control and monitoring respectively configuration and diagnostic purposes. The drive device and the control device may produce specific emergency messages in case of the detection of several device-internal failures.All process data, communication and application objects are listed in the object dictionary of the drive device. The object dictionary entries are accessible by means of specific communication services. The entries are uniquely addressed by the 16-bit index and the 8-bit sub-index.5.2 Structure of the logical PDSThe drive device shall support one of the modes of operation and may support several of them. The CiA 402 logical power drive system is modelled as shown in Figure 1.Figure 1 — CiA 402 logical power drive system model5.3 Use cases of the PDS5.3.1 GeneralThe drive device compliant to this profile specification may be configured and operated by means of dedicated communication services by the control device. The implementation of process data and configuration objects depends on the supported modes of operation.5.3.2 Use case engineeringThe configuration may be performed by the control device or by a dedicated tool device. The tool device may reside in the control device. The control device and the tool device use the same communication services to configure the drive device.5.3.3 Use case operation-controlThe drive device is normally operated by the control device implementing the generic PDS by means of controlword and target values. The kind of target value depends on the currently selected mode of operation. The drive device is monitored by the control device by means of the statusword and actual values. The kind of actual values depends on the currently selected mode of operation.6 Functional elements6.1 Device identification FE6.1.1 GeneralIn addition to the parameters defined in this specification, the CiA 402 profile defines some more identification parameters for the drive device and the motor.

The network management is network technology dependent.6.3.2 I/O dataThe network management master controls the PDS communication FSA by means of NMT messages. The drive device provides its communication status by means of network technology specific mechanism (e.g. CANopen defines the node/life guarding function and the heartbeat function). The status values are given in Table 6. The command values are given in Table 7.Table 6 — Status values for the communication FEIEC name CANopen name Details ReferenceCommunication running Operational 5d See /CiA301/127d or 4d See /CiA301/Communication stopped Pre-operational orStoppedTable 7 — Command values for the communication FEIEC name CANopen name Details ReferenceStop communication Enter pre-operationalor Stop remote node CS = 128dor 2dSee /CiA301/Run communication Start remote node CS = 1d See /CiA301/If the drive device and the control device like to exchange process data synchronously, the used network technology is responsible to achieve synchronous transmission.6.3.3 StatesThe Communication stopped state is equivalent to the NMT pre-operational or NMT stopped state. The Communication running state is equivalent to the NMT operational state.The synchronization is network technology dependent. In CANopen, each Process Data Object (PDO) may be configured individually to be transmitted or to be received synchronously. If synchronization is lost, the drive device may send an Emergency message. Another possibility is to use a global time base.6.3.4 ParametersThe parameters are network technology specific.6.4 Basic drive FE6.4.1 GeneralThis profile defines a PDS FSA that is controlled by the controlword received from the control device. This FSA provides sub-states, which are defined in detail in /CiA402-2/. The drive device provides the statusword, which is consumed by the control device.6.4.2 I/O dataThe status values are given in Table 8. The command values are given in Table 9.Table 8 — Status values for the basic drive FEIEC name CANopen name Details ReferenceOperating Operation enabled Bits 0 to 6 in Object 6041 00h See /CiA402-2/Table 9 — Command values for the basic drive FEIEC name CANopen name Details ReferenceOperate Start (reset) command Bits 0 to 3 and bit 7 in Object 6040 00h See /CiA402-2/6.4.3 StatesThe PDS FSA defined in detail in /CiA402-2/ specifies the possible control sequence of the drive device. A single state represents a special behaviour. The state also determines, which commands are accepted; e.g. it is only possible to start a point-to-point move when the drive is in the operation-enable state. States may be changed using the controlword and/or according to internal events.6.4.4 ParametersThe drive device’s behaviour may be configured by means of parameters via the network. The CiA 402 profile defines parameters to select the mode of operations among many others.
