Abstract
The invention relates to a glass fibre oil fume filtering felt and a production method thereof. The glass fibre oil fume filtering felt comprises an upper layer, a middle layer, and a lower layer, wherein the upper layer and the lower layer both have the thickness of 0.5 to 2.5 millimeters and the fiber glass filament quantity of 25 to 27grams per square meter; and the middle layer has the thickness of 8 to 20 millimeters and the fiber glass filament quantity of 50 to 150 grams per square meter. The production of the glass fibre oil fume filtering felt comprises the following steps: puting glass into a crucible device to melt to form fiber glass filament; winding the fiber glass filament around a rotary barrel, applying an adhesive at the same time, and forming an angle by the operating direction of the crucible and the cross section of the barrel; and laying the fiber glass filament after the winding of the fiber glass filament is stopped and shaping by drying. The glass fibre oil fume filtering felt has relatively large dust capacity and relatively small wind pressure loss, thereby facilitating industrial production. Furthermore, the glass fibre oil fume filtering felt can be one-step arranged and formed, thereby ensuring the stability and reliability of production and reducing the production cost.
Description
Technical field
The present invention relates to a kind of Fiberglas felt for filtering oil smoke and manufacture method thereof.
Background technology
During family expenses range hood work at present all is directly to be discharged into oil smoke in the air, perhaps employed filtering material can't satisfy multinomial requirement simultaneously, these requirements comprise can effectively adsorb oil smoke, enough oil smoke adsorbances are arranged again, air loss can not be big simultaneously, also require filtering material that the performance of waterproof and heat-resistant fireproof is arranged, material self is wanted environmental protection, in use can not discharge harmful material.Glass fibre itself is exactly a kind of inert material, its chemical property and physical property are all very stable under normal conditions, and self is the higher temperature of ability also, by our technological design, make the oil smoke adsorbance and the air loss of two-sided felt reach an equalization point, allow it satisfy this two requirements simultaneously.
Domestic existing technology and product all can't satisfy above-mentioned these requirements simultaneously, and such as fiberglass needled mat, it can be used as the air filtration felt and uses, and it is waterproof but also high temperature resistant not only, but its oil smoke adsorbance does not reach, and air loss is big; The chemical fibre felt that also has organic class, as expanded polypropylene, it can adsorb oil smoke, but material self non-refractory, the oil smoke adsorbance is also not enough; Nonwoven also can satisfy several performances, and air loss is adjustable, but water vapour contacts the easily soft distortion in back with it, and the oil smoke adsorbance is also not enough etc.
Patent CN02136507.5 discloses a kind of preparation technology of oil fume air filtering material, this technology comprise select materials, shredding, mixing with feed that cotton, combing, laying become net, preparation fire retardant adhesive, spray fire retardant adhesive, drying is reinforced, whole boiling hot, side cut rolling.Polyester fiber raw material after the shredding is carded to thin net, repaves and build up certain thickness fibre web, again fire retardant adhesive is sprayed onto drying reinforcing in back on the fibre web, whole boiling hot moulding.Make cooking fume filter with this material and pack in the products such as ventilation fan, range hood, not only can filter dust particle, also can filter the airborne liquid particle of oil smoke, purify air, what be beneficial to man is healthy.This preparation technology is easy to suitability for industrialized production, but products obtained therefrom does not have adsorption function.
In a word, the at present domestic material that satisfies above-mentioned these requirements simultaneously or relevant document, technical data and the report of also not searching.
Summary of the invention
The invention provides a kind of Fiberglas felt for filtering oil smoke, comprise upper strata, intermediate layer and lower floor, upper and lower two layers of thickness is 0.5-2.5mm, the glass fiber amount be 25-75 gram/square metre, intermediate layer thickness is 8-20mm, the glass fiber amount be 50-150 gram/square metre.
The upper, middle and lower layer of described Fiberglas felt for filtering oil smoke is made by by mass 70-85% glass fibre and 15-30% adhesive, and the diameter of glass fiber is the 20-30 micron.
The present invention also provides the manufacture method of above-mentioned Fiberglas felt for filtering oil smoke, glass is put into formation glass fiber in fusing back in the crucible equipment, glass fiber is wrapped on the cylinder of rotation, apply adhesive simultaneously, the traffic direction of crucible and the cross section of cylinder form angle, the speed of service of crucible equipment is adjusted to 6 ± 1.2 meters/minute when twining glass fiber, the linear velocity that cylinder rotates is controlled at 470 ± 50 meters/minute, the speed of service with crucible equipment after 25-75 minute is adjusted to 7 ± 1.4 meters/minute, the linear velocity that cylinder rotates is controlled at 565 ± 50 meters/minute, the speed of service with crucible equipment after 50-150 minute is adjusted to 6 ± 1.2 meters/minute, the linear velocity that cylinder rotates is controlled at 470 ± 50 meters/minute, stop to twine glass fiber after 25-75 minute, behind the laying glass fiber, the oven dry setting.
The mass flow ratio of glass fiber and adhesive is 70-85: 15-30.The adhesive that applies wants to satisfy the requirement of above-mentioned technology, normal temperature did not solidify in following 8 hours, moderate to the adhesion of glass fiber simultaneously, can be when initial applying glue the distribution of basic fixed glass fiber, before solidifying, allow to lay the glass fibre silk screen simultaneously, make it on thickness direction, can stretch, become the two-sided felt of glass fibre filtering oil smoke of predetermined structure after drying is solidified.
The traffic direction of crucible and the cross section of cylinder form angle, can make glass fiber in the rotation direction of circumferential cylinder surface upper edge cylinder with axially sprawl and come, treat that glass fiber is after the cylinder surface winding finishes, it is laid to the glass mat with predetermined thickness, obtains space network.The traffic direction of preferred crucible becomes an angle of 90 degrees with the cross section of cylinder.
The present invention is the netted structure of a kind of layer stereo, constitute by three layers of corrugated layer structure, three layers glass fiber amount is all different, laxer relatively but its thickness maximum in intermediate layer, obviously form, can well adsorb oil smoke by wave and curve, upper and lower two-layer comparatively more closely knit, one side prevents in the blower fan exhausting oil smoke filter felt of escaping out, and another side prevents under oil smoke drippage behind a certain amount of oil smoke of absorption; By the density that our production technology (as glass fiber winding time of the rotating speed of cylinder, the crucible speed of service, each layer etc.) is regulated glass fibre, air loss is also little simultaneously to make it reach suitable dust containing capacity; And glass fibre itself is with regard to the higher temperature of ability.The preferably environmental protection type of selecting for use of adhesive, as select epoxy-modified acrylic acid class adhesive for use, add the curing oven dry in our later stage, under still being high temperature, normal temperature can not discharge harmful material, also have fire-retardant effect simultaneously.
The present invention is easy to suitability for industrialized production, adopts glass fibre continuous strand production technology, and the setting of can once arranging in production process had both guaranteed the stable and reliable of production, had reduced production cost again.
