The definitions of terms given in this part are the same as those given in GB/T 11574 and G1/91,1. 3.1
Non-electrolytic zinc flake coating (self-lubricating or post-lubricating) Non-electrolytic zinc flake coating is subjected to appropriate heating to make the zinc flake, the zinc flake and the required material simply bond to form an inorganic coating with good self-lubricating properties and cathodic protection, except for some adhesive salts. 4 Overall durability
A major feature of the electrolytic zinc coating is that it can be added to the storage! , the added fasteners will not absorb the wind source: the standard release 1
GB/T5267.2--2002/2SO1C6B3:2000 treatment method will not produce new ecology such as oxygen spraying treatment in the process of coughing 1 will not bring hydrogen exposure tendency, the good result of the release method will lead to the collection of basic wind (brand washing, how to use the same case of 5 people, in the coating process to the user, the upper hall will be controlled: this point, the connection B/T3098.17 can be used as an example of the neck load test. It should be noted that the coating of the rotor has a high degree of hydrogen resistance, so it can be quickly Before the zinc coating process, the zinc sheet has been absorbed by hydrogen. During the heat treatment process, the detailed layer has passed the technical requirements and inspection of the size of the detailed layer. It meets the general requirements of 3/T147, E5/Y9145 and G/T216. The detailed layer is related to the basic tolerance given in Table 1. It is also related to the inner and outer diameters and the following tolerance band positions: - External source number: .f.en
The central diameter has sufficient requirements: H, the layer will not exceed the zero line basic size under the external compensation level), and the inner diameter will not contain the zero line. That is, when the tolerance band cannot mark the basic size of the line, the inner diameter with a tolerance position of H can be coated with the thickness of the layer! , the provisions of B/T3934: the position of the male stem is to be tested by the H gauge respectively for the external or internal effect, when the environmental gauge is used to control the test case, the maximum torque allowed is: 0.0012Vm), the mountain, or the nominal diameter (mm) other size requirements are only applicable to the lower road.
is to meet the specified protection performance (Chapter 1), when the minimum comprehensive layer is checked (..), the zinc coating thickness standard specification should be considered to be equal to the minimum coating thickness. Therefore, the estimated maximum coating thickness is the same as the minimum coating thickness required by the internal and external coatings, see the table. For layers with a minimum thickness of (tt), the applicable basic deviations are also given in Table 2. If the basic deviations given in Table 1 for a specified thermal runout do not meet the required minimum layer thickness, then the thread tolerance should be modified to a certain value (or the tolerance should be limited to a certain tolerance range so that the resulting solution is more effective: the internal effect reaches its upper value, the external effect is suitable for the lower value of the tolerance. The required minimum layer thickness is given in the table. Note: For the purpose of modification, see Appendix A of the material properties. If the minimum layer thickness is specified (see table), the thickness gauge can be used for measurement. In case of dispute, the microscope method according to the specification is used as the tensile force method.

(Informative Appendix)
GR/T5267.2—2002/ISO10683.2000 According to the anti-separation performance requirements, a user intends to order the following options: 10 coarse pitch thread (screw 1.5mm), non-electrolytic zinc flake dyeing. According to his experience, in order to meet the anti-separation performance requirements of the same situation: the minimum test time is 06. According to Table 5, the user decided to select the non-electrolytic zinc flake coating and the lead-acid treated zinc layer (door my) with a minimum thickness of 10m1. The corresponding minimum test time is 480h. According to Table 2, when the minimum thickness is 5m, the corresponding thickness is 10m, and the minimum basic deviation is 41mm.
According to Table 1, the user found that for the medium Chen, only the tolerance zone position is 1.5m: the minimum deviation can reach 11m. This means that the screw with a 6& before coating can not be accepted. The user's legal requirement is 1 and the explosion groove before the sheet layer is 6". The zinc sheet layer is obtained from this part. In order to avoid installation time, the thickness of the zinc sheet layer cannot exceed 11m. The user will order:
