The comparison of a heat-proof quality and a dirt performance:
In the average test temperature is that 30 ℃ and sample density are 35 kilograms/meter
3Condition under measure heat conductivility, sample No.4(sees Table 1) thermal conductivity be 0.0314 kilocalorie/mph ℃, and the heat conductivility of Comparative Examples is 0.0364 a kilocalorie/mph ℃. carry out the vibratory screening apparatus test according to JISA9523-1990, sample No.4 throughput is 0.24% as a result.And the throughput of Comparative Examples is 1.8%.
The comparison of drainage performance:
Pack into 2 gram glass wools that prescind or that smash to pieces (sample No.4 or control sample) and 1 liter of tap water in the mixing tank and with 1500 rev/mins of speed stirrings 30 seconds.Move into this mixture in graduated cylinder (1000 milliliters) and placed 15 minutes.The glass wool that sample No.4 prescinds swims in the water, at the bottom of control sample then absorbs water and is sunken to tin.
These test results are described as follows.Sample 2-4 can be blown into the space and form low-density thermally-insulated body.They not only have good drainage tool " rise dirt " trend less.Also can obtain similar result when satisfying following condition: the gap X between the delivery end 27 of guide plate 26 and the feeding roller 24 garden perimeter surface is between the 0.5-1.5 millimeter; The delivery end 27 of guide plate 26 and short cut on the roller 22 the gap Y between each tooth 40 between the 1-3 millimeter; Feeding roller 24 and weak point are cut the garden roll surface speed ratio of roller 22 1: 4-1: between 6, and short garden roll surface speed rotation of cutting roller 22 with the 25-35 meter per second; And after drying 0.5-3.0% by the content of treatment agent in glass wool that silicone and whiteruss are formed.
As gap X during less than 0.5 millimeter, not only prescinded too little piece by glass wool, nor may with uniform amount and adhesion send into this glass wool integral body.Another problem that is taken place is the glass fibre fracture.When gap X surpassed 1.5 millimeters, glass wool is whole just can not to remain between guide plate 26 and the feeding roller 24 fully effectively, to prevent that this glass wool integral body is prescinded into inappropriate bulk.
As gap Y during less than 1 millimeter, this glass wool integral body is prescinded too little piece.And the short Garnett line of cutting on the roller 22 will radially outward protrude by action of centrifugal force in the high speed rotating process, and this might make the tooth 40 and the delivery end 27 of guide plate 26 come in contact.When gap Y surpassed 3 millimeters, this glass wool is whole might to be prescinded into inappropriate bulk.
When short circumferential speed of cutting roller 22 during less than 25 meter per seconds, its behavior of prescinding will descend, even and adjust feeding roller 24 also can not the less glass wool piece of acquisition size with the feeding speed that reduces glass wool integral body 12.On the other hand, the garden roll surface speed of cutting roller 22 when weak point surpasses 35 meter per seconds, and it prescinds behavior with excessive, and the glass fibre in this glass wool integral body will rupture.
When feeding roller 24 and the short rim vdocity ratio of cutting roller 22 are in 1: 4-1: in the time of outside 6, will produce and lack the garden roll surface speed of cutting roller 22 and exceed the similar problem of 25-35 meter per second scope.
The residual volume of the treatment agent of forming when silicone and whiteruss in the glass wool integral body after the drying is less than 0.5% the time, and it just can not obtain essential drainage and dirt resistance effectively.Even when the residual volume of this treatment agent surpasses 3.0%, can not obtain to improve accordingly therewith as the performance of the glass wool of the finished product.
The method according to this invention collects in glass wool on the transfer roller and does not have stick to each other together structure of glass fibre, and this point is different with situation with caking agent.Therefore, when sending into this glass wool in the Garnett cutter, just can direct action it be prescinded the irregular fritter of forming shape, its size is even substantially, and unwanted influence can not take place, for example, a dirt of glass fibre, or the unwanted increase of dead small density.In brief, method of the present invention can make effectively be used for being blown between the interior and exterior wall or in the top ceiling to form the glass wool of high quality thermofin, they have good drainage and dirt resistance, and can not pollute wall or top ceiling surface or cause that fine particle plays dirt.
According to device of the present invention, can adopt a kind of glass wool that does not contain caking agent, and the top condition of cutting this glass wool integral body determines that easily these conditions are suitable to be used for realizing the efficient production small glass wool piece, these glass wool pieces have predetermined size and density.
