(2) cutting of reducing blast pipe board first marks line of cut in blast pipe board, then cuts with portable cutting machine, is less than or greater than the rotary corner plate at 90 ° of angles, when line, should calculate corner size, cuts after determining angle, to guarantee joining quality.
2, special-purpose adhesive
(1) airduct is made, is installed and must use special-purpose adhesive, to guarantee the bonding quality of airduct.
(2), before using special adhesive adhesive bonding, should remove the oil stain of location for paste, water stain, dust and foreign material etc.
(3) special-purpose adhesive is made up of pulvis A group and liquor B group two parts, at the scene by manufacturing firm's specification preparation.For guaranteeing the uniformity of special adhesive, should adopt electric blender to stir, forbid stirring by hand.
(4) special-purpose adhesive, under different ambient temperatures, has the different presetting times, and particularly, when ambient temperature is during lower than 0 °, special-purpose adhesive is more slow curing time.Special-purpose adhesive variation of ambient temperature, the airduct after its minimum presetting time and bonding allows the minimum time of installing to conform with the regulations.
Two, airduct is made
1, straight tube is made
(1) adopt on the both sides of airduct left side plate the blade varying in size, in the time of cut form plate, the step line of cutting combination use simultaneously, scrapes off the thermal insulation layer outside stepped line with instrument knife, and step position should guarantee the right angle of 90 °, and cutting surface should be smooth.
(2) on ladder surface, coat special-purpose adhesive, special-purpose adhesive is wanted evenly, and consumption should rationally be controlled, and avoids the remaining glue of extruding after airduct is tied up to cause too much waste, also affects attractive in appearance.
