Changzhou, it is city of level of Jiangsu province ground, be located in heartland of delta of Changjiang Delta, the Yangtse River, it is famous city of base of one of cities of center of area of delta of the Yangtse River, advanced manufacturing industry and culture travel, economy of Jiangsu the Yangtse River brings main component, with Suzhou, form Su Xichang city to encircle without stannum.
Mud of fire prevention of good DR-A3-CD02 of inferior quality of price of mud of Changzhou fire prevention is receive a dose to stick with organic synthetic resin, add the classics such as fire prevention agent, filling to Zhan is pressed and be become. This stuff is long not solidify, plasticity is very good, OK and aleatoric ground undertakes sealing blocking up. DR-A3-CD02 basically applies in building conduit and wire cable the fire prevention of perforative hole is sealed in blocking a project up, block bag of fire of makings, block up to cooperate to use with inorganic fire prevention.
Technical index:
A. The exterior: Plasticity solid, have certain flexibility
B. Density: 10 cube of 2 × Kg/m3
C. Be able to bear or endure ability in swimming: D: > 3 bilge without dissolve and craze
Fireproof limit: > 180minDR-A3-CD02 application limits: Apply to electric power, telegraphic, postal, chemical industry, factory, enterprise, building and subterranean project to seal an all sorts of perforative content, like cable, vitta, wind canal, tracheal reach metallic conduit to wait cross lie between strong or the fire prevention space of all sorts of cable bridge that form when secondary floor, have fire prevention function, special application punchs in minor cable native place hole, aperture and other block fire are blocked up makings is unfavorable a different that block up hole and change the place with relatively frequent cable.
Inferior quality of price of mud of Changzhou fire prevention has very much alone DR-A3-CD02 and inorganic fire prevention are blocked up makings match construction---To the burrow project of large area, often disassemble in order to need, can choose this way. A few petty aperture, use DR-A3-CD02 achieves construction goal extremely easily, but the burrow that accumulates to bedding face, because it is soft, cannot finalize the design, very inaccessible construction asks, use to the construction of big burrow so organic block up with inorganic makings the construction method that match. Also can use inorganic to block up makings, block fire is wrapped alone or associated construction.
(1) the choice is more than electrical wiring, cable to use the sectional plastic pipe that grows to block a wall up at sealing, cut open, set go up in the wire cable that uses section of a construction project, make cover the plastic pipe in wire cable can move freely and again ideal is with electrical wiring cable is a center, of wire cable all around can lap one centimeter organic an aperture of makings.
(2) after afore-mentioned jobs had been done, inspect the burrow size that wants construction to nail patternmaking board, the inorganic that blocks mix up up is blocked up makings.
(3) inorganic blocks makings use method up to use reach with makings computation---This expect in construction Shi Xiangen occupies need to seal the size of plug-hole hole, estimation blocks the dosage of makings up, next a makings put the scale that 1 ∶ 0.6-0.7 presses inside container to join clear water agitate to become use instantly mushily, if dosage is bigger when, normally mark second finish. Every time agitate quantity is controlled in 5 kilograms. Seal to larger hole when blocking up, but right amount reinforcing steel bar in order to increase period intensity, seal a ply basis to need to decide, general not less than 15 centimeters. 1m3 of fill hole bulk. Need expects this 1.3 tons.
(4) is blocked up when inorganic makings make end about 15 minutes, tear open go plastic bushing, can be in aperture fill organic a makings. DR-A3-CD02 construction needs sue for peace to examine:
(One) the construction of professional construction group that fire prevention seals a project to should train qualification by the course, the safe skill in labour and labor are safeguarded wait for demand, should according to the country active concerned regulation is fulfilled.
(2) following and preliminary work should do before construction:
1, represent the skill demand with related product, admit and nap spot condition.
2, should mix according to thing of construction of spot state provision safety of construction staff person upholds the wanted work requirement such as equipment.
3, the applicability that answers fire prevention to seal a data, quality and associated test report or the one by one such as certificate undertakes probation.
4, fire prevention seals those who block a data up to pack should hold to in good condition, label of paste child conformity certification, indicate useful date, store method and construction method.
Inferior quality of price of mud of Changzhou fire prevention should make specific record to checking gain very much.
Construction site should plan data check area beforehand. The fire prevention of each type seals a data, should wait by corresponding temperature, humidity store environmental demand undertakes storing.
(4) the construction that fire prevention seals a project wants severity to press depict construction graph and file of corresponding construction craft technical ability undertake, must not change at will.
(5) the fire prevention of be shadedby foilage is sealed there should be inspect manage unit to examine in stifling engineering construction process approbate, fill in account of corresponding construction of engineering of be shadedby foilage.
