Abstract
A process for preparing the thermally insulating refractory calcium silicate plate for building, furnace, etc includes preparing raw slurry, colloidizing at 80-140 deg.C for 3-30 hr while stirring, making plate by different 4 approaches, steam curing, drying and machining.
Description
(1), technical field: the manufacture method and the device that the present invention relates to a kind of calcium silicate thermal insulation PLASTIC LAMINATED.Belong to the extraordinary building materials technology field of heat-insulating, fire-preventing.
(2), background technology: existing calcium silicate thermal insulation PLASTIC LAMINATED is by cement, and three kinds or more kinds of raw material of doing in diatomite, quartz, pulverized limestone, coal ash, asbestos, the mica etc. according to a certain ratio, are used wet-process moulding, and static maintenance forms.This plate bulk density is big, the mechanical strength height, and heat resisting temperature is low, and general density is 1.0～1.3g/cm
3, rupture strength is 4～15MPa, and heat resisting temperature is no more than 650 ℃, and advantage is the intensity height, and breadth is big, and cost is low, but as fire proofing material, weak point has 2 points: one, heat resisting temperature is too low, does not claim the PLASTIC LAMINATED what is real; Two, density is big, and heat conduction is fast.The objective of the invention is to overcome the deficiency of above-mentioned prior art and heat-insulating fire-proofing material, make and satisfy heat resisting temperature, and a whole set of production equipment is provided at the calcium silicate thermal insulation PLASTIC LAMINATED more than 1000 ℃.
(3), summary of the invention: for reaching above-mentioned purpose, it is on 98102760.7 the basis that the name that the present invention proposed on July 3rd, 1998 is called " a kind of manufacture method of calcium silicate thermal insulation fireproof material " patent No., moulding again and transformation through process modification and production equipment, produced heatproof more than 1000 ℃, rupture strength surpasses the calcium silicate thermal insulation PLASTIC LAMINATED of 2MPa.

2, method for making: referring to Fig. 1
2.1 being added water mill to silica flour in grinding machine, silica flour all passes through 10000-hole sieve.
2.2 the non-crystalline silicon micro mist adds the water dispersed with stirring, 80～400 rev/mins of rotating speeds, 10～120 minutes time.
2.3 adding water, calcareous material is digested to milk of lime, also can be directly with calcium lime powder or slaked lime powder batching.
2.4 quartzy fine powder and non-crystalline silicon micro mist use separately or mix with arbitrary proportion, add milk of lime or slaked lime powder or calcium lime powder, mixed slip CaO/SiO
2Mole ratio be that C/S is 0.95～1.05.
Account for the fiber that has disperseed of total amount 2-8% and 0～20% wollastonite in powder 2.5 in above-mentioned slip, add, stir.
2.6 above-mentioned slip is added gelatinization tank, Gu add water to water/weight ratio is 2～10, with Steam Heating, in 80 ℃～140 ℃ scopes, kept 3～30 hours, carry out gelatinization reaction, in this process, stir all the time, control makes and does not material suspendedly precipitate, and is generally 40～400 rev/mins, gel ends, and need be cooled to normal pressure.
2.7 above slip input laminator or making sheet unit are made sheet material, laminator or making sheet unit have four kinds, corresponding to four kinds of equipment four kinds of plate-making methods are arranged, referring to Fig. 1-5:
1. the press filtration extrusion forming method of mixing: slip dewaters through filter press, extrudes slab again after the vacuum muller mixes, and is pressed into sheet material on press.
2. the press filtration extrusion moulding that mixes: slip dewaters through pressing the Shanghai machine, and after the vacuum muller mixed, extruding roll forming on extrusion shaping machine was sheet material again.
