What woodiness prevents touchhole is flame retardant processing

What woodiness prevents touchhole is flame retardant the fireproof limit that quality matters to door of woodiness fire prevention, because a lot of this fire prevention doors produce an enterprise to establish this working procedure the special process reference point in be manufacturing process, but as a result of flame retardant the procedure with working procedure mature lack, those who cause each manufacturer is flame retardant craft each are not identical, flame retardant technology is very not sound, cannot assure flame retardant quality, serious when bring about fire prevention door fireproof limit is reduced, the life property security that gives people causes potential hidden trouble. Our company save pupil of the earliest woodiness fire prevention to produce a business as me, in manufacturing process of more than 10 years, fumble stage by stage give opposite relatively mature flame retardant craft, induce now arrange as follows, with period undertake with brotherly manufacturer the technology is discussed, adjure professional personage to offer criticism make a comment or criticism.

Of lumber commonly used flame retardant the method has: Spray law, immerse the law, evaporate law that boil, vacuum law, vacuum pressurization law. Spray law and immerse the lumber face that the law uses at undertaking dig cuts treatment no longer commonly, and ply the thin plate under 10mm is flame retardant processing, do not apply to woodinessPrevent touchholeproduction. Although vacuum law and vacuum pressurization law are flame retardant the effect is admirable, but because its equipment is costly, in me door of province fire prevention is produced had not seen in the enterprise use. At present I save enterprise of fire prevention door to use evaporate to boil a law to undertake mostly flame retardant processing. The author thinks, using evaporate to boil a law to undertake flame retardant the following should notice when processing:

1, wait for flame retardant lumber Yi Gan not also wet

Wait for flame retardant the moisture content of lumber is an influence lumber is flame retardant a of quality main factor. Because dry wood is entered flame retardant pool hind often is absorbed more easily flame retardant fluid, and lumber is absorbed flame retardant what the quantity of fluid affects lumber directly again is flame retardant quality, its uptake and flame retardant the oxygen index of lumber and flame retardant deepness concerns into direct ratio. Lumber is absorbed flame retardant juice is more, index of better, oxygen jumps over the flame retardation of lumber tall, flame retardant deepness is deeper. However not little company thinks, anyway lumber is in flame retardant when even by flame retardant fluid is soaked, so lumber moisture content nods low high to do not have how old relation, wait for flame retardant lumber to be handled without stoving commonly, individual business just will curium the Shi Fangmu of solution undertakes even flame retardant processing. The moisture content just that whoes not to know lumber can be affected flame retardant quality, cause flame retardant of lumber flame retardant quality is not stable. According to the experiment, be in identical flame retardant below the condition, moisture content the lumber under 15 ％ relatively the lumber of 40 ％ can raise moisture content prep above above of 5 oxygen index, flame retardant deepness raises 3mm above.
