Abstract
The invention relates to application of expanded perlite to a ship deck and a deck structure. According to the application method, expanded perlite with reasonable formula is developed, the expanded perlite is prepared into cement expanded perlite by setting a reasonable raw material proportion and then conventional cement mortar leveling method is adopted, so that the application of the expanded perlite to the ship deck is smoothly realized. The deck structure comprises a deck layer and a cement expanded perlite layer in sequence from bottom to top, wherein the cement expanded perlite layer is bonded with the deck layer. According to the application, the cement expanded perlite is used for replacing the currently used primary deck coverings, so that the properties of the obtained deck structure can well satisfy the requirements; and the density of the cement expanded perlite is low and the paving thickness is not limited, so that the weight of the deck structure is greatly reduced, the net weight of the ship body is lightened, the local overweight phenomenon is mediated and eliminated and the stability of the ship body structure is improved.
Description
Technical field
The present invention relates to the pearlstone Application Areas, is application and a kind of deck construction of pearlstone on ship deck specifically.
Background technology
The deck is the important component of hull, is in the ship structure, is positioned at the above two dimensional structure of tank-top plate, is used for space in the capping ship, and with its horizontal subdivision stratification.The deck is the steel plate on the ship beam, and hull is separated into the upper, middle and lower layer.
The deck that connects continuously total length at the last layer of proper hull is called upperdeck, also claims the first deck.Following each layer deck general designation orlop deck is followed successively by the second deck, third deck etc.The following local deck that arranges of upperdeck is called platform deck or platform.The deck that plays a major role in guaranteeing ship strength is called the strength deck.Being provided with the strength deck of the naval vessels of short bridge or round house, generally also is upperdeck.
Each layer deck and platform that upperdeck is above are referred to as superstructure deck, are followed successively by from the bottom to top 01,02,03 deck etc.Perhaps name respectively according to the major function of its position, such as forecastle deck, bridge deck, poop deck, and promenade deck, navigation deck, monkey island etc.
The horizontal camber in deck is called camber, is used for getting rid of rapidly the ponding on the deck, and broken-line type, curvilinear style etc. are arranged.For living quarters, generally need to guarantee ground level so that therefore inhabitation safety need to carry out the deck crown levelling.Existing deck crown levelling mainly usefulness be primary deck covering, primary deck covering commonly used has: latex cement, the deck composition of A60 type composite fire, A60 type floating fire-resistant deck covering, portland cement concrete, acid-proof cement, alkaline resisting cement and polyurethanes deck composition, the general density of these materials is all larger, and applied thickness there is certain requirement, applied thickness such as latex cement is 8 ~ 12mm, the applied thickness of the composite fire deck composition of A60 type and A60 type floating fire-resistant deck covering is about 50mm, portland cement concrete, the applied thickness of acid-proof cement and alkaline resisting cement is 30 ~ 40mm, the applied thickness of polyurethanes deck composition is 10 ~ 18mm, therefore often weight is larger for formed deck construction, so that the net weight of hull increases greatly, especially for the larger zone of camber, it is excessive and affect the stability of hull structure to form easily local weight, and the construction environment of this class deck construction requires high, and cost is larger.
Pearlstone be a kind of nontoxic, tasteless, do not fire, be stale-proof, product that acid and alkali-resistance, insulation, sound-insulating and heat-insulating, inside are polynuclear plane, through fragmentation by material from acidic volcanic glass matter lava (perlite), be sized to certain particle size, again through preheating, the high-quality heat-insulating material of a kind of white of making at high-temperature delayed sintering more than 1400 ℃ or light color, its density is about 150kg/m
3, folding strength is about 38Mpa, water-intake rate＜2%, and thermal conductivity is about 0.055W/mk.This product is mainly used in the insulation, heat insulation of building roofing and body of wall; The aglite of material of construction; Various industrial equipmentss, pipe insulation layer; The inwall of various deep coolings, freezer engineering; The soilless culture of agricultural and gardening, improvement soil, preserve moisture and fertility etc. are widely used in the industries such as oil, chemical industry, electric power, building, metallurgy, and aspect boats and ships temporarily without widespread use.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, technical problem to be solved by this invention provides the application method of a kind of pearlstone on ship deck, and provides a kind of lightweight and be not subjected to the deck construction of applied thickness restriction.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
The application of a kind of pearlstone on ship deck, described pearlstone are the pearlstone that includes the component of following massfraction:

Described pearlstone and Portland cement add water with the ratio of 1:1 and mix and stir into behind the cement expanded perlite sand-cement slurry routinely and criticize the method for gear levelling and construct on the deck layer of ship deck to form the cement expanded perlite layer, and the performance perameter of described cement expanded perlite is as follows:
Tap density: 93kg/m
3Thermal conductivity: 0.055W/mk;
Water ratio:＜2%; Use temperature :-256 ~ 800 ℃;
Granularity: 0.5 ~ 1.5mm, 2 ~ 3mm wherein one or both.
The present invention is by the pearlstone of development rational formula, and by being set, rational material rate pearlstone is mixed with the method that adopts again behind the cement expanded perlite conventional sand-cement slurry to criticize the gear levelling, realized smoothly the application of pearlstone on ship deck, because the density of cement expanded perlite is low, applied thickness is unrestricted, therefore can substitute well primary deck covering commonly used at present, the weight of deck construction is reduced greatly, the hull net weight is alleviated, the local reconstructed image of crossing is reconciled elimination, and the stability of hull structure is improved.
In order to solve the problems of the technologies described above, another technical scheme that the present invention adopts is:
A kind of deck construction comprises deck layer and cement expanded perlite layer from bottom to up successively, and described cement expanded perlite layer and described deck layer are bonding.
Wherein, described cement expanded perlite layer forms after the sand-cement slurry method of criticizing the gear levelling is constructed on the deck layer on deck routinely by cement expanded perlite, described cement expanded perlite adds water by pearlstone and Portland cement with the ratio of 1:1 and mixes and stirs and form, and described pearlstone is the pearlstone that includes the component of following massfraction:
SiO
2：69~72%； Al
2O
3：12~18%； K
2O：3~4.5%；
Na
2O：3~4.5%； CaO：0.1~0.2%； MgO：0.2~0.5%；
And the performance perameter of described cement expanded perlite is as follows:
Tap density: 93kg/m
3Thermal conductivity: 0.055W/mk;
Water ratio:＜2%; Use temperature :-256 ~ 800 ℃;
Granularity: 0.5 ~ 1.5mm, 2 ~ 3mm wherein one or both.
Wherein, also comprise the flow leveling deck dressing layer, described flow leveling deck dressing layer is positioned at the top of described cement expanded perlite layer and bonding with described cement expanded perlite layer.
