Four, the construction requirements

1 S950 inorganic filler sealed cable before pouring, should make thesurface of the cable box (box) and inner surface cleaning.

2 for perfusion liquid S950 inorganic filler sealed cable need, thelower ends or cable drum cable frame with a SW type cable sealingexpansion of plugging material sealing.

3 S950 type inorganic filler using methods and materials cable sealingcalculation:

A. S950 type inorganic filler sealed cable A components and Bcomponents of the blending ratio of 10:6.5 (weight ratio). The factory has been in the above proportion respectively arranged on: (A) 10Kg(B) powder, liquid 6.5Kg two containers, in order to prevent thepowder precipitated at the bottom would group A powder transferred into a homogenized like silk body component B liquid of the materialcan be used after (also can be the B component liquid pour the filling into the component of A powder, but must be fully stirred, prevents the bottom powder not mix). Construction of the ambient temperatureS950 Filler Type Inorganic cable sealing allowed is -5 ~ 40 ℃.

B. S950 inorganic filler sealed cable powder and auxiliary fluid (liquid)according to the matching requirements of mixing into slurry silk fitagain for casting. (winter construction may be appropriate to increase the mixing time, S950 inorganic keep pouring in the cable box packingin condensed powder and liquid time without separation,)

The C. B component assisted liquid (liquid): antifreeze, solidifying,regulating the construction time, proportion (Table 1) execution.

D. perfusion method can use gravity or pressure method can.Generally uses the gravity method, pay attention to filling quantity andbeat box perfusion (cylinder) wall, between the ease of S950 inorganicfiller sealed cable into the cable. The cable box (cylinder) such aslimited to difficult construction conditions, inconvenience of gravitymethod, the compression method. Perfusion can be used 1-3 times;the first perfusion cable box (cylinder) bottom about 50mm thickness(SW cable material blocking preventing collapse), the second infusioncable box (cylinder) volume ratio 2/3, third perfusion cable box (box)of all air volume.

4 filler (powder) and the auxiliary fluid (liquid) to prepare a standard(Table 1)

Project indicators

Formulated with auxiliary liquid

The weight ratio of powder: auxiliary liquid =1: (0.65 ± 0.05)

The construction time (20 ℃) the fluidity of 60min ± 15min

Note: the construction time is related to environmental temperature,environmental temperature is high, can shorten the construction period, the ambient temperature is low, the construction time.

Auxiliary liquid (B) dosage can be adjusted according to the construction time, but must ensure that the minimum amount shall not be less than A material (powder): auxiliary liquid (liquid) =1:0.5), the most amount of not more than A material (powder): auxiliary liquid(liquid) =1:0.65. See (Table 1)

5 solidification and solidification time (table two)

Project indicators

Ambient temperature of 20 ℃ condensation ≤ 24h

Curing ≤ 72h

Fully cured ≥ 30 days

Note: if the environment temperature is below 20 degrees or ventilation conditions are poor; S950 inorganic filler sealed cable boxof materials in the cable can be extended completely curing time, the quality of the products will not affect.

6 perfusion of powder (A) and liquid (B) mixing time (table three)

The ambient temperature -5 ℃ to 20 ℃ ambient temperature of 20 ℃ to 40 ℃

7-8min 3-5min

Note: for reference. Because the stirring speed, there is a direct relationship between auxiliary liquid dosage, temperature, but must ensure that the slurry can be fit after perfusion of silk.

7 note

A. in the casting process of stock must be stirring, can extend the construction time, otherwise it will be condensed to thick or condensation, is strictly prohibited to add auxiliary dilution casting.

B. strictly enforce the ratio requirements and operating requirements

C. or the use of water instead of the factory to provide auxiliary liquid(liquid)

D. found A component (powder) agglomeration is failure, can notcontinue to use.

E. single cable box (box) 5Kg above two to three perfused with powder(must be completed in 24 hours).

F. in the last frame (cylinder) perfusion at the still depressed phenomenon, must also fill fill.

Five, packaging

S950 type inorganic filler sealed a two-component plastic packaging,generally A components (powder) 10kg/ barrels, group B (auxiliary liquid) 6.5kg/ barrel.
