COMMONWEALTH OF AUSTRALIA R04 1( PATENTS ACT 1952 COMPLETE SPECIFICATION FOR OFFICE USE: Class Int.Class Application Number: Lodged: Complete Specification Lodged: Accepted: Published: Priority: Related Art: Oa Name of Applicant: RHONE-POULENC CHIMIE Address of Applicant: 25, Quai Paul Doumer, 92408, Courbevoie, France Actual Inventor: Adrien Dromard and Claude Richard Address for Service: SHELSTON WATERS, 55 Clarence Street, Sydney Complete Specification for the Invention entitled: "STABLE AQUEOUS SUSPENSION OF SILICO-ALUMINATES" The following statement is a full description of this invention, including the best method of performing it known to us:- 1 STABLE POUB3S SUSPENSION OF SILICO-ALUIfNATES SThe present invention concerns the preparation of stable aqueous suspensions of silico-aluminate and the use thereof in the paper-making Ii industry.
Aqueous suspensions or slurries of silico-aluminates are used in a number of fields, in particular in the paper-making industry.
Now, those suspensions have a tendency to undergo sedimentation i or gelling, which makes it difficult for them to be transported or i stored. Indeed, in very many cases, following transportation of the 'i suspension or after storage thereof over a period of greater or lesser S' 10 length, the deposit of a hard layer of pigment above which is a slurry j which is more fluid but which has a low content of dry matter is Sobserved. It is also often impossible to put the silico-aluminate back into a state of suspension or to produce a slurry which is of i sufficiently low viscosity to be pumpable and therefore capable of use in an industrial context. That therefore involves a certain problemn.
Q
The main subject-matter of the invention is therefore a suspension of silico-aluminate which is stable, pumpable and dispersible o°o°°o after several days storage.
0 00 Q oe For that purpose the stable aqueous suspension according to the invention is characterised in that it ccmprises a silico-aluminate and, as a stabilising agent, a biogum.
It has been found that after storage for several days, the suspensions of the invention exhibited no or only little sedimentation and in every case remained of suitable viscosity.
Other features and advantages of the invention will be better appreciated frnom the following description and specific but non-limiting examples.
2 The invention is applied more particularly to synthetic silicoaluminates and in particular amorphous silico-aluminates.
In accordance with a particular embodiment of the invention the suspension is based on an alkali metal silico-aluminate, in particular of sodium.
In the latter case, products of the following formula may be mentioned: I, xNa20, A1203 y SiO 2 wH20 in which .0 x 0.1 to 2; y 1.5 to 16; w 0.3 to 4.
0o The synthetic silico-aluminates which are suitable for use in 0 0 accordance with the invention may be produced by any known method which however is not included in the scope of the invention. Generally, the °.o0 operating procedure involves neutralisation of a silicate with an 0°.o aluminium salt, in particular aluminium sulphate, or an aluminate.
0 .0 15 In accordance with a preferred embodiment of the invention the S0 suspension is based on a silico-aluminate produced by precipitation and formed by a filter cake which results from the precipitation reaction and o0. which is slaked.
0 00 In other words, precipitation of the silico-aluminate is effected in particular by reaction of a silicate with aluminium sulphate or an aluminate, as has been indicated hereinbefore. The reaction medium is then filtered and the result is a filter cake which is washed if necessary. The cake is then slaked, thus forming a suspension which, in the embodiment referred to herein, constitutes the suspension of the invention which is stabilised by the means described hereinafter.
It may also be noted that it is possible to add to that suspension dry silico-aluminate, in particular in powder form, so as to i increase the amount of dr- matter in the susoension.
The stabilising agent used is a biogum.
Biogums are polysaccharides of high molecular weight which is generally higher than one million, produced by fermentation of a carbohydrate under the action of a microorganism.
Biogums that may be mentioned as being suitable for use in the suspension in accordance with the present invention include those produced by fermentation under the action of bacteria or fungi belonging to the genus Xanthcnnas such as Xanthcmonas begoniae, Xanthcmonas campestris, Xanthcmonas carotae, Xanthoronas hederae, Xanthomonas incanae, Xanthornonas malvacearum, Xanthcrronas papavericola, Xanthcmonas phaseoli, Xanthcnonas pisi, Xanthcmonas vasculorum, Xanthononas vesicatoria, Xanthcrronas vitians and Xanthomonas pelargonii; the genus Arthrobacter and more particularly the species Arthrobacter stabilis and j 15 Arthrobacter viscosus; the genus Erwinia; the genus Azotobacter and S, more particularly the species Azotobacter indicus; the genus Agrobacter and more particularly the species Agrobacterium radiobacter, Agrobacterium rhizogenes and Agrobacter turefaciens; the genus Alcaligenes and more particularly the species Alcaligenes faecalis; the genus Rhizobium; the genus Sclerotium and more particularly the species Sclerotium rolfsii and Sclerotiun glucanicum; the genus Corticium; the genus Sclerotinia; and the genus Stromatinia.
The biogum to be used, which can be produced by fermentation by means of the above-described microorganisms, is more particularly the gun produced by fermentation of bacteria of the genus Xanthcmonas.
It will be appreciated that the use of a mixture of biogurs as a stabilising agent would not be a departure from the scope of the present invention.
It is advantageous to use an anti-bacterial agent of the type ccrnprising for example sodium benzoate, glutaraldehyde and formaldehyde, Sif 44 in combination with the biogum.
The biogum is generally used in an amount which varies between 0.05% and 5% by weight with respect to the dry matter and more particularly between 0.1 and 1%.
The proportion of dry matter in the suspension is usually at least 15%, preferably at least 25%. The amount of aluminium expressed as Al203 varies in most cases between 0.5 and In accordance with another preferred embodiment of the invention, the suspension is subjected to a crushing operation. The crushing operation makes it possible to reduce the median diameter of the par-ticles of the silico-alunTinate.
The crushing operation is carried out in such a way as to produce for example a silico-aluminate which has a median particle diameter of between 0.5 and 20 pm, more particularly between 1 and 10 m.
I I It has been found that the crushing operation makes it possible 2' to increase the stability of the suspension in respect of time.
It will be noted that generally speaking, when the suspension is subjected to a crushing operation, the biogum is added after the crushing operation has been carried out. However, the addition of biogrn to the 1, 40020 suspension prior to the crushing operation is not excluded.
The suspensions of the invention may be used to advantage in the paper-making industry in the production of paper or cardboard in particular as a filler either in the body of or for coating of the paper or the cardboard. It will be appreciated that they are likewise suitable for all the usual uses of that type of substance, for example for polishing carpositions, binding agents for catalytic coapositions, additives for paints and for concrete and building and plastics materials.
Examples will now be set forth.
EM*PLE 1 A filter cake of sodium silico-aluminate of the following composition is taken directly from the filter in the production process: 80.0% of SiO 2 9.35% of Al 2 0 3 5.75% of Na 2 0, which in the finished state after drying has a BET surface area of 100 m2/g and a DOP absorption level of 170 ml/100 g. The firing loss of the cake is 74.3%.
The cake is slaked so as to produce a fluid pumpable slurry with a pH-value of That slurry is processed in a laboratory DYNO crusher provided with a 0.6 1 glass bowl cooled by a double jacket and containing 450 cm3 of glass balls of a diameter of 1.5 mn. The rate of crushing is and the flow rate at the outlet of the crusher is 250 cn3/min.
Introduced by means of a four-blade turbine into the highly fluid crushed suspension which is produced in that way (rrmedian diameter of the S particles is 2.2 usn), is xanthane gum of the type Rhodopol 50 MC which is marketed by RHONE-POULENC, in the following proportions: i i 450 g of crushed slurry (115 g of dry matter), and 1.15 g of Rhodopol 50 MC.
20 The mixture is agitated for 40 minutes at 600 rpmn.
No deposit is observed after a period of 10 days. After a period of 40 days, a sedimentary volrume (solid voltue/total volume) of less than 1% is observed.
I
The fluidity of the product is good and its viscosity remains stable in respect of time.
C(XMPARATIVE EXMPLE 2 The slurry which is prepared and crushed as in Example 1 is left at rest without the addition of xanthane gum.
6 Total sedimentation is observed after a eriod of 4 days. It is !.4 impossible to put it back into suspension.
EXAM1PLE 3 The starting point for this Example is the slaked cake of Example 1 but it is not crushed. The median diareter of the particles is 11 .n.
0.25 g of RHODOPOL 50 MC is added to 450 g of slurry (115 g of dry matter), and agitation is effected as in Exarmle 1.
SNo deposit is observed after a period of 10 days. After 40 days, ,a sedimentary volume of the order of 5% is observed.
EXAMPLE 4 i The starting point for this Example is the slaked cake of Example I t 1. Added to 3500 g of that cake are 136 on3 of 1.5 N H 2
SO
4 and 569 g of dry silico-aluminate in powder form. The solids content of the is then 34% and the pH-value is 8.9.
A crushing operation is effected, producing a highly fluid suspension (median particle diameter 2.3 j-n).
S2g of RHODOPOL 50 MC is added to that suspension and the mixture is agitated as in Example 1.
The mixture obtained, by virtue of its concentration, is in the t 0.
form of a gel of low viscosity (after 17 days the viscosity is 57 mPa.s) which can be easily fluidified by applying a low level of stress energy (1 minute at 500 rpn).
EXAMPLE 5 The starting point for this Example is a dry sodium silicoj 1 Aded o 500g o tat akea2 3 2'3 of 0 wit NH- ad pH6valu of aluminate of the formula: Na20, Al 20 3 14 SiO2 320 with a pH-valu of a firing loss at 90 0 C of 12%, a DOP absorption level of 170 ml/id g, a BET surface area of 10. 2/g and a coracted density of 0.3.
Lf?7 A g o RHDOPL 50MC s adedto tat uspnsin an th mitur is aitatd a in xampe 1 3 g of RHODOPOL 50 MC is added to 2500g of a suspension of 575 g of the above-indicated dry product in water. Agitation is effected for 1 hour. The final pH-value is 9.7.
After a period of 7 days, the suspension is still fluid. After 10 days, a sedimentary volume of 15% is observed. The suspension can be easily fluidified by applying a low level of stress energy (1 minute at rpm).
It will be appreciated that the invention is in no way limited to the embodiments described which have been set forth only by way of example. In particular it comprises all means constituting technical equivalents for the means described as well as combinations thereof if they are used within the scope of protection as claimed.
