Description
Selvherdende vannglasskitt. Self-hardening water glass putty.
Til herdning av vannglasskitt har i lengere tid saltene av kiselfluorvannstoff-syre vært kjent. De tilkommer den ulempe at ved innvirkning av sterkere syrer og varme kan fluss-syre frigjøres fra den herdnede kittmasse. Dette influerer enten på sammenklebingen av de med kittmas-sen sammenmurte syrefaste stener eller sammenklebingen av vannglasskitt på me-taller som bly, stål eller edelstål. Det er også vist at den frigjorte fluss-syre ved destillasjonsprosesser forsvinner fra det utmurede kar og deretter slår seg ned på apparaturens koldere deler, og her frem-bringer korrosjon. The salts of silicic hydrofluoric acid have been known for a long time to harden water glass putty. They have the disadvantage that when exposed to stronger acids and heat, hydrofluoric acid can be released from the hardened putty mass. This influences either the bonding of the acid-resistant stones that are bricked together with the putty mass or the bonding of water glass putty on metals such as lead, steel or stainless steel. It has also been shown that the hydrofluoric acid released during distillation processes disappears from the bricked vessel and then settles on the colder parts of the apparatus, and here produces corrosion.
Til herdning av vannglasskitt, dvs. blandinger av vannglassoppløsninger og inerte fyllstoffer som kvartsmel er det allerede foreslått anhydrider av organiske syrer, indre estere av glykolsyre og ami-der av fettsyrer. Anhydrides of organic acids, internal esters of glycolic acid and amides of fatty acids have already been proposed for hardening water glass putty, i.e. mixtures of water glass solutions and inert fillers such as quartz flour.
Det er nu blitt funnet at kiselfosforsyre overraskende er spesielt godt egnet til herdning av vannglasskitt, og derved oppnås fremragende egenskaper slik de hittil ikke var kjent ved vannglasskitt. It has now been found that silicic phosphoric acid is surprisingly particularly well-suited for hardening water glass putty, and thereby achieves outstanding properties that were not previously known for water glass putty.
Vannglasskitt som er herdet med kiselfosforsyre, imidlertid spesielt den med kiselfosforsyre som er fremstillet ifølge belgisk patent nr. 590 925 er bestandige såvel overfor syrer av alle konsentrasjo-ner unntatt fluss-syre som også overfor koldt og kokende vann. I en rekke av disse kiselfosforsyreherdnere ble det funnet et karakteristisk hittil ukjent røntgendia-gram. Som spesiell fordel og i motsetning til alle tidligere vannglasskitt har de med kiselfosforsyre herdede vannglasskitt som i første rekke finner anvendelse til mu-ring og fuging av syrefaste stener i såkalte syrebygg, den egenskap at kittingen ikke mere som tidligere behøver å etterbehand-les med en syre eller en magnesiumsilico-fluoridoppløsning. De er allerede bestandige uten en hvilken som helst etterbe-handling overfor vann av en hvilken som helst temperatur. Water glass putty hardened with silicic phosphoric acid, however, especially that with silicic phosphoric acid produced according to Belgian patent no. 590 925, are resistant both to acids of all concentrations except hydrofluoric acid and also to cold and boiling water. In a number of these silicic phosphoric acid hardeners, a characteristic hitherto unknown X-ray diagram was found. As a special advantage and in contrast to all previous water glass putties, the water glass putties hardened with silicic phosphoric acid, which are primarily used for masonry and grouting of acid-resistant stones in so-called acid buildings, have the property that the putty no longer needs to be post-treated with a acid or a magnesium silico-fluoride solution. They are already resistant without any post-treatment to water of any temperature.
De følgende eksempler tydeliggjør i de-talj det hittil anførte. The following examples clarify in detail what has been stated so far.
Eksempel 1. Example 1.
Først fremstilles ifølge belgisk patent nr. 590 925 en kiselfosforsyre. Herved inndampes 5200 g av en kjemisk ren fosforsyre av en utgangskonsentrasjon på 76 pst. H,,P04 i kvartsdigel i åpen luft inntil dens konsentrasjon er øket til 76 pst. P2Os. Man lar det avkjøle til 40° C, innfører 600 g tørr kolloidal feilet kiselsyre under om-røring. Blandingen oppbevares i 10 dager ved 110° C i ovn. First, according to Belgian patent no. 590 925, a silicic phosphoric acid is produced. Hereby, 5200 g of a chemically pure phosphoric acid with an initial concentration of 76% H,,P04 is evaporated in a quartz crucible in the open air until its concentration has been increased to 76% P2Os. It is allowed to cool to 40° C., and 600 g of dry colloidal fused silicic acid are introduced while stirring. The mixture is stored for 10 days at 110° C in an oven.
Etter denne tid fordeles den på for-hånd avkjølte blanding og oppslemmes under kraftig omrøring i 30 1 tørr diisopro-pyleter. Deretter frasuges pånytt og for å fjerne den resterende overskuddsfosfor-syre gjentas prosedyren med mindre eter-mengder ennu 2 til 3 ganger. After this time, the previously cooled mixture is distributed and suspended under vigorous stirring in 30 1 of dry diisopropyl ether. It is then aspirated again and to remove the remaining excess phosphoric acid, the procedure is repeated with smaller amounts of ether another 2 to 3 times.
Filterkaken tørkes under milde betin-gelser i vakuum eller til 100° C i tørke-skap. The filter cake is dried under mild conditions in a vacuum or to 100° C in a drying cabinet.
Man får 1500 g kiselfosforsyre av den analyttiske sammensetning 26,9 pst. Si02 og 63,8 pst. P2Os. Stoffet er et løst, i for-hold til P205 svakt hygroskopisk pulver som oppløser seg klart i vann til en konsentrasjon på 10 pst., idet en mengde på 1 g i 100 ml oppløses på ca. 2 minutter. 1500 g of silicic phosphoric acid of the analytical composition 26.9% SiO2 and 63.8% P2Os are obtained. The substance is a loose, weakly hygroscopic powder in relation to P205 which dissolves clearly in water to a concentration of 10 per cent, as a quantity of 1 g in 100 ml dissolves in approx. 2 minutes.
2 deler av den således fremstilte kiselfosforsyre med en kornstørrelse 99 pst. av 2 parts of the thus produced silicic phosphoric acid with a grain size of 99 per cent
finere enn 14 maskeskikt (196 masker/cm2) 2,5 deler kaolin, 47,5 deler kvartsmel W 10, 47,5 deler kvartsmel GM blandes godt ved hjelp av en egnet mekanisk innretning (sikteanalyse av kvartsmel W 10 og kvartsmel GM: finer than 14 mesh layers (196 meshes/cm2) 2.5 parts kaolin, 47.5 parts quartz flour W 10, 47.5 parts quartz flour GM are mixed well using a suitable mechanical device (sieve analysis of quartz flour W 10 and quartz flour GM:
Denne blanding, i det følgende beteg-net som kittmel, utrøres med 37 vektsdeler av et vannglass som inneholder 7,5 deler Na20, 25,5 deler Si02 og 67 deler H?0, har en spesifikk vekt på 1,33 og ved 20° C en viskositet på ca. 38 cP til et godt forar-beidbart plastisk, klumpefritt kitt. Bear-beidelsestid: 30 minutter, herdningstid: 24 timer. This mixture, hereinafter referred to as putty flour, is stirred with 37 parts by weight of a glass of water containing 7.5 parts Na 2 O, 25.5 parts SiO 2 and 67 parts H 2 O, has a specific gravity of 1.33 and at 20 ° C a viscosity of approx. 38 cP to a good workable plastic, lump-free putty. Bear curing time: 30 minutes, curing time: 24 hours.
Dette kitt tjener til sammenmuring av syrefaste stener i reaksjonsstorm hvori det opptrer saltsyreavspaltende stoffer eller salpetersyre. Kittingen utmerker seg ved en trykkfasthet (500 kg/cm2) målt på en sylinder av 25 mm høyde og 25 mm dia-meter med en god klebeevne på stålman-tel 15—18 kg/cm2 og en god klebeevne på keramisk sten, 12 kg/cm2. Ved fylling av en utmurt kjele eller et reaksjonstårn med vann viser kittingen ingen angrep heller ikke når vann opptrer som første påkjenning for det utmurte kar i stedet for syre. This putty is used to bind together acid-resistant stones in reaction storms in which hydrochloric acid-releasing substances or nitric acid appear. The putty is distinguished by a compressive strength (500 kg/cm2) measured on a cylinder of 25 mm height and 25 mm diameter with a good adhesion to steel casing 15-18 kg/cm2 and a good adhesion to ceramic stone, 12 kg /cm2. When filling a bricked boiler or a reaction tower with water, the putty shows no attack, even when water acts as the first stress on the bricked vessel instead of acid.
Eksempel 2. Example 2.
2 vektsdeler kiselfosforsyre, 2,5 vektsdeler kaolin, 47,75 vektsdeler kvartsmel W 10, 47,75 vektsdeler kvartsmel GM sammenblandes til en homogen blanding i en egnet apparatur. Kornstørrelsefordeling til-svarende eksempel 1. Deretter blir dette kittmel utrørt til et godt plastisk kitt med et vannglass som består av 11,2 pst. K20, 24,5 pst. Si02, 64,3 pst. vann og har en spesifikk vekt på 1,32, og dermed utmures en stålsvovelsyrebeholder. Kittet viser likeledes en god bestandighet såvel overfor svovelsyre som også overfor vann også når vann er kittets første påkjenning. Den sammenblandede kittmasses forarbeid-ingstid utgjør ved 20° C 25 minutter, herdningstiden 24 timer. 2 parts by weight silicic phosphoric acid, 2.5 parts by weight kaolin, 47.75 parts by weight quartz flour W 10, 47.75 parts by weight quartz flour GM are mixed to a homogeneous mixture in a suitable apparatus. Grain size distribution corresponding to example 1. Next, this putty flour is stirred into a good plastic putty with a glass of water which consists of 11.2 percent K20, 24.5 percent SiO2, 64.3 percent water and has a specific weight of 1 ,32, and thus a steel sulfuric acid container is walled off. The putty also shows a good resistance to both sulfuric acid and water, even when water is the putty's first stress. The processing time of the mixed putty is 25 minutes at 20°C, the curing time 24 hours.
Det skal fremheves at kitt med kiselfosforsyre som herdner likeledes har en god klebeevne på betong. Ved fravær av fluss-syre har vannglasskitt som herdnes med kiselfosforsyre meget gode klebeev-ner som ikke forandrer seg under påkjen-ningen. It should be emphasized that putty with silicic phosphoric acid, which also hardens, has good adhesion to concrete. In the absence of hydrofluoric acid, water glass putty that hardens with silicic phosphoric acid has very good adhesive properties that do not change under stress.
Eksempel 3. Example 3.
1 vektsdel kiselfosforsyre, 2,5 vektsdeler kaolin, 48,25 vektsdeler kvartsmel W 10, 48,25 vektsdeler kvartsmel GM, korn-størrelsen se eksempel 1, sammenblandes med 37 deler av et vannglass, som består av 8 vektsdeler K20, 20 vektsdeler Si02 og 71,8 vektsdeler vann til et plastisk godt be-arbeidbart, klumpefritt kitt. Denne blan-dings bearbeidbarhetstid utgjør ca. 15 minutter, herdningstiden 16 timer. På grunn av dets relativt korte herdningtid er vannglasskitt ifølge eksempel 3 spesielt egnet for reparasjoner på de driftssteder hvor det kommer an på en snarlig drifts-gjenopptagelse. 1 part by weight of silicic phosphoric acid, 2.5 parts by weight of kaolin, 48.25 parts by weight of quartz flour W 10, 48.25 parts by weight of quartz flour GM, grain size see example 1, are mixed with 37 parts of a glass of water, which consists of 8 parts by weight of K20, 20 parts by weight of Si02 and 71.8 parts by weight of water to a plastic, easily workable, lump-free putty. The workability time of this mixture amounts to approx. 15 minutes, curing time 16 hours. Due to its relatively short curing time, the water glass putty according to example 3 is particularly suitable for repairs at operating locations where a quick resumption of operation is essential.
Eksempel 4. Example 4.
3 vektsdeler kiselfosforsyre, 2,5 vektsdeler kaolin, 47,25 vektsdeler kvartsmel W 10, 47,25 vektsdeler kvartsmel GM (korn-størrelse-fordeling se. eks. 1) sammenblandes med 36 deler av et vannglass som består av 14,5 vektsdeler K20, 27,2 vektsdeler Si02 og 58,3 vektsdeler vann og som har en spesifikk vekt av 1,42, en viskositet på 50 cP ved 20° C til en plastisk godt for-arbeidbart klumpefritt kitt. Dette kitt viser en spesiell høy klebing såvel på kera-miske stener (20 kg/cm2) som også på stål (40 kg/cm2). Dessuten viser kittet et relativt lavt porevolum på ca. 12 pst. Dette kitt egner seg spesielt til utmuring av 3 parts by weight silicic phosphoric acid, 2.5 parts by weight kaolin, 47.25 parts by weight quartz flour W 10, 47.25 parts by weight quartz flour GM (grain size distribution see example 1) are mixed with 36 parts of a glass of water consisting of 14.5 parts by weight K 2 O, 27.2 parts by weight SiO 2 and 58.3 parts by weight water and which has a specific gravity of 1.42, a viscosity of 50 cP at 20° C. into a plastic well-workable lump-free putty. This putty shows a particularly high adhesion both to ceramic stones (20 kg/cm2) and also to steel (40 kg/cm2). In addition, the putty shows a relatively low pore volume of approx. 12 percent. This putty is particularly suitable for bricklaying
blandingssyrebeholdere (med blandings-syre forståes i teknikken vanligvis blandinger av salpetersyre og svovelsyre i veks-lende mengdeforhold). mixed acid containers (mixed acid in the technical sense usually means mixtures of nitric acid and sulfuric acid in varying proportions).
