Rice.
So far, although concrete pathogenesis in human body for the mineral fibres are not also clearly unified the understanding, pass through
Nearly 60 or seven ten years research and probes, newest research results particularly in recent years, in the many to Health Impact for the mineral fibres
Aspect has reached common recognition, and these know together fine for ensureing health, safe handling mineral fibres and the solvable mineral of new bio
The development of dimension specifies direction.In the production of fiber, using scene, the aerial concentration of fiber, generally acknowledge in the world at present
Standard is that every milliliter of in the air is not higher than 1 fiber.Fibre diameter is thin and short then easily to float in atmosphere, is thus more easy to
Produce the air of higher fiber concentration.The physical dimension of fiber is to determine that can fiber suck the key factor of deep lung.Mesh
Before, typically using 3 μm of fibre diameter as cut off diameter.The crude fibre that high 3 μm of diameter is typically only capable to rest on upper respiratory tract system
System, can be obtained by effectively removing by mucus system and musculation function.For the fine fibre less than 3 μm for the diameter just relatively
It is easily accessible deep lung, and be possible to potentially hazardous to health generation.And it is possible to potential to health generation
Harm.In this case, the length of fine fibre plays the part of important role.Because, for shorter fine fibre (generally less than 20
μm), they can be cleaned out pulmonary as common dust by macrophage.And for longer fine fibre (generally less than 20 μ
M), macrophage is helpless, can only station in deep lung, by the dissolving of lung liquid, corrodes and to dispose.Fiber is in Human Lung
Solvability in liquid plays the effect of key for the elongated fibers time of staying stationed in deep lung.As fruit fiber exists
Human lung's time of staying is long, then will result in the inflammation of lung localized sustained, and the probability of induction pulmonary lesion just greatly increases.
Although elongated fibers generally only account for sucking the 15% ~ 20% of fiber total amount, substantial amounts of experiment shows, elongated fibers are in pulmonary
The time of staying be induction pulmonary lesion key factor.The chopped fiber that macrophage completely removes suction pulmonary typically requires
The time of more than 70 day, as long as and constant of dissolution rate is more than 100ng/ (cm2.hr mineral fibres) can be completely molten less than 70 days
Solution is in lung liquid.
Constant of dissolution rate (k in simulation Human Lung liquid for the fiberdis) it is indicated fibrolysises performance.Simulation human body
Lung liquid generally adopts gamble solution (molar concentration * 103): nacl 116, nh4Cl 10, nahco327, glycine 5, Fructus Citri Limoniae
Sour sodium 0.2, cacl20.2, cystine (l) 1, h2so40.5, nah2po41.2, dtpa 0.2, abac are 50ppm.Generally
Think, the constant of dissolution rate of effect bio-soluble mineral fibres should expire kdisMore than 100ng/ (cm2.hr), the half-life is less than
7 days.
European Union index knb specifies that 0 class is to be not classified as carcinogen, and its average fibre diameter is more than 6 μm, and the present invention is first
European Union's knb index is met from size for being not classified as carcinogenic requirement.
Preferably, needling density is 100～400 thorns/cm2, depth of needling be 8～13 millimeters.
It is to pierce pricker repeated localised puncture fleece using the buckle of needing machine that needle point method reinforces refractory fibre net, makes fiber middles
Horizontal refractory fibre is divided to form vertical fibers cluster, this fiber cluster, from top to bottom through fibre web, by being tangled with horizontal fibre, is hindered
The only mutual slippage of fiber, and make fibre structure closely, thickness is greatly reduced.In the technological parameter of needing machine needling density,
This two parameters of depth of needling are mostly important.Refractory fibrous material is fragile material, easily snaps off, in traditional refractory fibre pin
In thorn technique, the needling density of less clear and definite acupuncture and depth of needling, the strength of refractory fibre needle punched fabric is not had substantially
Concern.Its reason is perhaps that traditional refractory fibre is used for heat-treatment furnace, the industrial heat preservation material of heating furnace uses, by force
Power requires less.But in daily life, fabric is inevitably acted on by stretching, bending repeatedly, the stretching of fabric
Ultimate strength, fatigue performance then must receive publicity.But inventor's experiment finds, this two technological parameters are to refractory fibre
The tension failure strength of needle punched fabric, fatigue performance have significant impact, are related to its use.It is highly preferred that acupuncture is close
Spend for 300～400 thorns/cm2, depth of needling be 11～13 millimeters, the now tension failure of obtained refractory fibre needle punched fabric
Strength can obtain higher value, and fatigue performance is preferable.
Preferably, described thermal finalization stage by stage is to be incubated 35～105 minutes under the conditions of 500～700 DEG C of temperature, then with
10～60 DEG C/minute are warming up to 1200～1400 DEG C and process 2～5 minutes, are disposed, naturally cool to room temperature.
Traditional refractory fibre needle punched fabric formed or a thermal finalization after i.e. warehouse-in preserve it should be noted that fire resisting
The internal stress of fibre prickling fabric is not eliminated, and has the generation of deformation during warehouse-in preserves.For this problem, this
Invention eliminates the internal stress of colored solvable refractory fibre needle punched fabric using thermal finalization twice, and thermal finalization twice adopts different
Temperature and time.After thermal finalization twice, the dimensional stability of colored solvable refractory fibre needle punched fabric is improved, invention
People thinks, thermal finalization twice is more beneficial for being formed that crystal grain is tiny, more densification, intensity are higher, the preferable refractory fibre of toughness.
Preferably, the color of described colour calcium and magnesium soluble fiber needle punched fabric is in yellow, black, redness and green
A kind of.The beneficial effects of the present invention is: (1) prepares colored refractory fibre first, is a weight to netrual colour refractory fibre
Supplement；(2) gained colour calcium and magnesium solubility refractory fibre fault of construction is few, has higher lung liquid rate of dissolution, it may have
Good structural stability；(3) raw material being used is all common Inorganic Chemicals on market or natural mineral products, not only becomes
This is low, and nontoxic, no any dusty gass release, is conducive to environmental protection to produce.
