Description

A7 B7 修 ίΤ- supplement 5. Description of the invention (), ZrOi, Ti (U), solubility of various ingredients, excess value of SiO2 (as defined above).毎 値 The sample has a good expansion ratio of 3 · 5% or less at 1 260 ° C, which is indicated in bold type. If some composition ratio cannot be made into fibers, or the solubility of the made fibers is difficult to measure, it is marked with X's. The following describes a standard mode: All fibers in the A line and above contain Sih excess value of 2 1. 8πιο less than 1%, and the stretch ratio measured at 1 2 6 G ° C exceeds 3.5%. For fibers not measured at 1 260 ° C, at more than one or two temperatures, more than half of the measured expansion ratios exceed 3.5%. Fibers above the B line and below the A line all contain CaO above 24 mol%, and also exhibit high stretch ratio. Fibers above the C line and below the B line all contain Ti02 2.7596 and above, and also have a high expansion rate. The applicant measured with a differential scanning calorimeter that the liquid temperature of the titanium-containing fibers appeared at 120 (TC, This has a high degree of damage to the fire resistance of the fiber. Line D (KW-1) fiber is an aluminum silicide material, which is not a salt water soluble substance. The aluminum component accounts for 20 ffi 190 as the upper limit, which seems quite reasonable. The grouping of fibers below the D line is as follows The MgO, CaO, and Zr02 relative amount lines below the E line (inclusive) are excessive CaO fibers (the first region in the first), and the E lines below the F line are excessive MgO fibers (the second region in FIG. 1). F Below the line are excess Zr02 fibers (the third region in Figure 1). The fibers in each group are classified according to the excess value of S0z. First, the excess Zr0i fibers, except for BZ — 42 9, all reach 1260 ° C stretch rate standard. BZ — 4 29 has a stretch rate of 4.1% at 1 260 ° C, but this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm).

V. Description of the invention () The present invention is about a method for making objects refractory and insulating. , Non-metallic, non-crystalline, inorganic oxidized refractory fiber materials, especially glass fibers made of silica and its main components. Inorganic fiber materials are well known and have a wide range of applications (for example, for the manufacture of large thermal insulation or sound insulation boards, or felts, vacuum formed shapes, vacuum formed boards and paper, ropes, yarns or textiles; building material reinforcing fibers; composition Automobile brake block composition) "&gt; In most applications, the main characteristics of inorganic fiber materials are heat resistance and often include resistance to strong chemical corrosion. Inorganic fiber materials can be glass-like or crystalline. "One of the asbestos pseudo-inorganic fiber materials, but it is very easy to cause people to suffer from respiratory system diseases." Although it is still unclear what kind of asbestos structure effect, it has led people to comment on the system. The main cause of the disease, only certain researchers are convinced, is roughly related to its mechanical effects and particle size. Critical size particles of asbestos can penetrate cells in the body, and the cells are constantly damaged, causing adverse effects on human health. Regardless of whether this structural effect is true, relevant government agencies have shown that they will adopt a product classification measure. Any inorganic Fiber products that have an adverse effect on the human respiratory system must be marked with the word "dangerous", regardless of whether the classification measures are based on sufficient evidence. Unfortunately, this type of inorganic fiber material is widely used, but there are no real alternatives. Therefore, there is an urgent need to find inorganic fibers that have the least danger and are objectively determined to be safe. According to a study, if the manufactured inorganic fibers have the characteristics of being soluble in physiological saline, they will not accumulate in the human body for a long time, so the damage to human health can be avoided or reduced. The danger is mainly determined by the length of the exposure period, so this concept is indeed the paper size applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) &quot; -4〆 (Please read the precautions on the back before filling in this Page) Packing--Order j &quot;-CAS101 BZ-14 CAS · *-71 765 ®-23 734 973 971 BZ 丨 27 Bz-S 78 A2-19 A ^ la ro'3 ωζ FREE one B3-26 IBZ.21 I iA2,23 B2-12 A'-932 7-U s-11 § 712 3-2 ° A2-25 B'201 694 A2-11 ^ 3-21 692 rom BZ.22 卬 3-25 ws i Λ2- 14 A2-35 924 696 v ~ \ bM \ to oc ο 8 ο S σ &gt; § 〇 &gt; Λ Ρ Κ ο σ &gt; μ ω κ &gt; ο σ &gt; 〇 &gt;-^ ί〇co Ν ^ ω * 2- ^ Ο Ο Λ.

Description of the invention ( )-. · Reasonable. Asbestos tincture is highly insoluble. The interstitial fluid of human cells has the same properties as saline solution in nature, and the solubility of fibers in saline has been recognized for a long time. If the fiber is soluble in physiological saline and it is assumed that its soluble component is non-toxic, then this soluble fiber must be safer than those insoluble fibers: the shorter the time that the fiber accumulates in the human body, the less harmful it is to the human body . H. Forster in "Behavior of Mineral Fibers in Physiological Saline" (Copenhagen IREC Annual Record of the World Health Organization 1982, Copenhagen, Volume II, pages 27-55 (1988)). Behavior in saline. Among them, various soluble fibers have been discussed in this article. The fibers shown in International Patent Application No. W087 / 05D07 contain magnesium, tidal, calcium, and aluminum below 1 Q% by weight, and are soluble in saline. The solubility of the fibers shown is measured in ppm units of silicon (quenched from the fiber's silicon-containing minerals) in salt water and soaked for 5 hours. According to the examples, the maximum value is 67PPID silicon. For comparison and measurement adjustment, the maximum value shown in the Forster article is equivalent to about 1 ppb β. The maximum value shown in the international patent application, if converted to the same measurement as the Forster article, the extraction rate will reach Each kilogram of fiber contains 90 1,500 milligrams of sand, which is 69 times higher than the fiber tested by Forster. In the Forster test, the fiber with the highest extraction rate is glass fiber, which has a high content of 鹸. Composition, so it has a low melting point characteristic. Therefore, it has no doubt that it has better performance, so that different factors such as the test solution and the length of time have been taken into account. International patent application number W089 / 12032 shows another kind of soluble salt Fibers in water, and it is mentioned that certain components may appear in this type of fibers. These components include hafnium dioxide ZrO2, and the document states that the proportion (by weight) of the constituent fibers used in the process is: 0.06 ~ 10 This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm) (please read the precautions on the back before filling this page): ¾.

Invention Description () The fibers shown in these previous technical documents have very different fire resistance. Among them, the fire resistance (when used as a refractory insulation material) can reach up to 8 1 5 ° C (1 5 〇 〇 T) 〇 At present, the temperature of salt-soluble fiber on the market exceeds 81 5 ° C. 傺 SUPERWOOL (trademark) products, the manufacturer is The Morgan Crucible Company Plc has a maximum operating temperature of 1050 ° C and a composition-to-weight ratio of 65% SiOjA, 29% CaO, 5% MgO, and 1% AUO3. Another similar fiber is INSDLFRAX (trademark) product, manufactured by Carborundum Company. Its continuous use temperature limit can reach 1Q0 (TC (1832 ° F)), and the melting point is 1 260 ° C (2 3 0 0 ° F). The composition weight ratio is: Si! U accounts for 65%, CaO accounts for 31.1%, MgO accounts for 3.2%, 03 of fish accounts for 0.3%, and 0.3%. 0 ZrO can be used as a component of aluminum silicide fiber to achieve high temperature resistance The first disclosed facts (see European Patent D 144349 for details), however, whether its characteristics can be transferred to saline-soluble fibers is still open to question. However, according to the above-mentioned international patent case W089 / 12Q32, it does not seem to be transferable. Applicants of the present invention It has been found that the specific combination ratio of fibers (including fibers containing oxidized sulfur dioxide) can be used at temperatures up to more than 1260 ° C. The applicant understands that the main factor for the fibers to be damaged by high temperatures is that the fibers become opaque and crystalline. During this change, if the residual content of silicon is insufficient, the fiber will be damaged due to the expansion and contraction rate exceeding 3.5%. Based on this, the applicant is focused on studying what substances will be formed when the fiber becomes opaque and crystalline. The first figure is the triaxial combination ratio of the three components CaO, MgO and ZrOi in the fiber composition of the case. The other various minor components are omitted, and the percentages are allocated on the three components so that the proportions of the points are equal. It is 100%. Among them, the area with number one represents CaO fiber (the proportion of CaO is larger than its ___e —----- This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) --- ----- itch ------, tT ------ 『Γ '. ..

In the fiber, when CaOSMgO + ZZrOz, all MgO are combined into Ca0.Mg0.2Si0z; all ZrOi are combined into ZCaO.ZrOi.lSiOy and excess CaO is combined into CaSi03. This type of fiber is located in the first region in the first one, and is hereinafter referred to as excess CaO fiber. In the fiber, where MgO &gt; CaO, all CaO are combined into Ca0.MgO.2Si02; all ZrO ^^ are combined into ZrOi.SiO ^, and excess MgO is combined into MgO Si〇2 ^ such fibers 僳The second region of one is referred to below as excess MgO fiber.

S i excess value, the total amount of silicon is subtracted from other components CaO, MgO, and Zroa, and the difference is obtained during the crystallization. In most joint ratio studies, the aluminum element also appears to a considerable degree. Therefore, the applicant also considers the aluminum crystal as AU〇j. Si02 to calculate the excess value of Si. This value also deducts β for other chemical components. , Similar considerations apply. The importance of the physical quantity basis of excess SiOi is that it can indicate the amount of remaining silicon, and other components. When crystallized into silicide, the glass can be kept transparent. In addition, the silicide formed during crystallization is at 1 2 60 ° C. It may become liquid or flow at high temperatures, resulting in stretching. Potential liquid components, such as alkali metals, the content must be controlled at a low level (the titanium effect discussed below) 〇 This paper size applies to Chinese national standards (CNS> A4 size (210X297 mm) ~ ~ 'J- -------, 'Installation-/ IV' (Read the notes on the back and then fill out this page) Order.

(: when it is 3.5% or less1) This fiber can be composed of (in terms of molecular weight percentage, impurities are not included) CaO &lt; 24ffl01%, its equilibrium status The following components include SiOz, MgO, and may also include Zr (^ and / or AU〇3, and accidentally mixed into the substrate, where the excess Si0z is more than 21.8mol% e. The applicant found that the excess CaO in the excess CaO composition is excessive. Value ratio, for other components, must be increased, especially at high Ca0 value, so for CaO in the fiber &gt; 20mol%, the amount of SiO ^^ must be greater than 23.7mol%. The applicant also found that those fibers It has good expansion and contraction at 1260 ° C. Its solubility depends on the amount of MgO, so Zr02 and A1j03 are key factors in determining fiber solubility. The present invention therefore also provides better soluble fibers in saline, as described above, where the excess of MgO [defined as MgO — (ZrO; ^ + Α1α03)] is greater than 10 mol% It seems that this type of fiber has a total solubility greater than 5Qppm MgO + SiOi + CaO (see the measurement description below). The excess value of MgO should preferably exceed 11.2mol%, so that the fiber can have a high solubility above 100ppra. Central Ministry of Economic Affairs Printed by the Standards Bureau employee consumer cooperative (please read the precautions on the back before filling out this page). The applicant's investigation found that the range of composition ratio in terms of salt water solubility and fire resistance is based on CaO / MgO / Si02 The fiber is added with additional components A1a〇3, ZrOjn TiO ^ and the like. The traditional method is to blow the melt out of the melter. However, the present invention is not limited to the blow molding fiber. Other possible methods. Table 2 shows the results of these tests and shows the linear expansion and contraction at temperatures of 6 QQ, 1 Q 0, and 1 2 6 (TC (not every sample is tested at every temperature); composition Weight hundred Ratio (according to the composition CaO, Mg〇, Si02, Al_2〇j This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) '-Produce A7 B7 repair-supplementary V, description of the invention (), Zr〇i , Ti (U), solubility of various ingredients, excess value of SiO2 (as defined above).毎 値 The sample has a good expansion ratio of 3 · 5% or less at 1 260 ° C, which is indicated in bold type. If some composition ratio cannot be made into fibers, or the solubility of the made fibers is difficult to measure, it is marked with X's. The following describes a standard mode: All fibers in the A line and above contain Sih excess value of 2 1. 8πιο less than 1%, and the stretch ratio measured at 1 2 6 G ° C exceeds 3.5%. For fibers not measured at 1 260 ° C, at more than one or two temperatures, more than half of the measured expansion ratios exceed 3.5%. Fibers above the B line and below the A line all contain CaO above 24 mol%, and also exhibit high stretch ratio. Fibers above the C line and below the B line all contain Ti02 2.7596 and above, and also have a high expansion rate. The applicant measured with a differential scanning calorimeter that the liquid temperature of the titanium-containing fibers appeared at 120 (TC, This has a high degree of damage to the fire resistance of the fiber. Line D (KW-1) fiber is an aluminum silicide material, which is not a salt water soluble substance. The aluminum component accounts for 20 ffi 190 as the upper limit, which seems quite reasonable. The grouping of fibers below the D line is as follows The MgO, CaO, and Zr02 relative amount lines below the E line (inclusive) are excessive CaO fibers (the first region in the first), and the E lines below the F line are excessive MgO fibers (the second region in FIG. 1). F Below the line are excess Zr02 fibers (the third region in Figure 1). The fibers in each group are classified according to the excess value of S0z. First, the excess Zr0i fibers, except for BZ — 42 9, all reach 1260 ° C stretch rate standard.

Description of the invention () This result may be caused by experimental errors (detailed below). Secondly, the pseudo-excess MgO fibers, except for BZ-59, have reached an acceptable expansion and contraction rate. It is also possible that the type of β-excess CaO fibers is not obvious due to test errors. In the excess CaO strands, some of them reached the standard of upper and lower stretch ratios, while others could not be reached, and will be explained later. BZ-418, BZ-33 and BZ-29 fibers have relatively low elongation and may cause test errors. In fact, they should have good elongation. BZ — 37, BZ-421 and BZ-416 may show that the excess SiOz value in excess CaO fibers is better than the 21.8% level indicated by excess MgO and excess Zr02 fibers. Similarly, the applicant also recommends that when the excess CaO fiber exceeds 0,010% in 2011, the 8102_ excess value must exceed 23.7%. BZ-30, BZ_ 422, BZ- 417 and BZ- 432 The test results are abnormal and may be caused by the appearance of melt flow components. However, the trend shows that the performance of CaO fibers is not good (probably because of the formation of CaSi03, which has not Formed in excess MgO or excess ZrO2 fibers), so low-CaO fibers have better performance. Β If boldly inferred, it shows fibers composed of high-MgO, low-CaO, low-Zr02, and low-A1Z03 fibers. It will have quite high solubility and low expansion ratio. Based on the applicant's experience, this type of fiber is not easy to make (see groups A2-33, Α2-32, Α2-28). Fibers of the same grade, because the content of SiOi is too high, is difficult or impossible to make. The exact critical value is not easy to determine, so the present invention only covers fibers that can meet the above-mentioned expansion and contraction requirements. Applicants are performing higher temperature tests on certain fibers.

BZ—400, BZ-36, BZ—46, and BZ-61 fibers were tested for expansion and contraction at 1,300 ° C. The results were as follows: 6.2%, 17.9%, and 19.6%. And 3.1%. BZ — 61 belongs to the region of excess MgO. The applicant speculates (because 2Ca0.Zr (U.4Si02 is not formed in this region). The main cause of the failure of the test at 1 300 ° C due to this component injury β is the fact that the fiber The elongation rate depends on the temperature (most of the unqualified fiber elongation rates appear in the temperature range 1260 ° C 〃 1300 ° C, and 1300 '~ 1 350 ° C), so provide a clue to force the test error Occurred. A standard test furnace is easily changed in the range of 1250 ° C to 1270 ° C when it is operated at a nominal temperature of 1260 ° C (front to back of the furnace, or from the center to the furnace) Wall), and instantaneous changes (when the thermostat is started or when the power supply is stopped). Therefore, a temperature difference of 20 ° C is likely to cause the sample at the same set temperature, sometimes it is reached, and sometimes it cannot reach 3.5% expansion rate.
