Detailed Description
The present invention will be described in further detail below.
The invention discloses a waterproof heat insulation construction process for an ice cold storage pool, which comprises the following steps:
base layer treatment: the inner wall of the ice cold storage pool is treated before construction, so that the upper side, the lower side and the four side walls of the ice cold storage pool are firm and clean, and phenomena such as hollowing, loosening, shelling, cracking, pulverization, oil stain and the like cannot occur. If the unevenness is encountered, the unevenness is chiseled or leveled off, and the place with the oil stain is wiped clean by using an organic solvent.
And (3) spraying construction: the polyurethane hard foam waterproof heat-insulation material is sprayed on the inner side wall of the ice cold storage pool, the polyurethane hard foam waterproof heat-insulation material is sprayed in a layered mode, and the distance between a nozzle and a construction base surface is preferably 800-1200mm during spraying. And each layer of spraying thickness is not more than 12mm, and after each layer of polyurethane hard foam waterproof heat-insulation material is foamed and hardened, the next layer of polyurethane hard foam waterproof heat-insulation material is sprayed until the polyurethane hard foam waterproof heat-insulation material is foamed to reach the designed thickness.
During spraying construction, the inner side wall and the top wall of the ice cold storage pool are firstly sprayed, and the bottom surface is finally constructed.
After the spraying construction is finished, a water storage test of the ice cold storage pool is carried out, and whether the ice cold storage pool leaks or not is detected every time the ice cold storage pool is placed to a depth of 1 m. And if the leakage phenomenon exists, spraying a layer of the leakage area again, and detecting the leakage phenomenon again.
The polyurethane hard foam body adopted by the invention is composed of two component liquid raw materials of polyol and isohydric acid ester, and a fluorine-free foaming technology is adopted, so that a thermal reaction is generated under a certain state, and a hard foam body compound, namely the polyurethane hard foam body with the closed cell rate of not less than 95%, is generated. When the polyurethane hard foam waterproof heat-insulating layer is sprayed, spraying equipment of GRACO/GUSMER company in America is mainly adopted. The equipment consists of a main control system operated by a computer and auxiliary systems for heating, circulating, conveying, spraying and the like. The component A is polyol, the component B is isocyanate, and the two liquids are pumped into the equipment by two pumps A, B respectively. After being heated, pressurized and proportioned by equipment, the polyurethane hard foam waterproof and heat-insulating material is conveyed to a specially-made spray gun by a pipeline to spray atomized liquid on the inner side wall of the ice cold storage pool, and the polyurethane hard foam waterproof and heat-insulating material is rapidly foamed and cured to generate a polyurethane hard foam compound with high density and pore closing rate higher than 95 percent, so that a waterproof and heat-insulating integrated waterproof and heat-insulating layer is formed.
When the polyurethane hard foam waterproof heat-insulation material is sprayed, the relative humidity is less than 75%, because when the relative humidity of the air in the ice storage tank is too high, when the polyurethane hard foam waterproof heat-insulation material is in a foaming reaction, the water vapor in the air can be attached to the reaction surface of the polyurethane hard foam waterproof heat-insulation material, so that the water in the foaming process of the polyurethane hard foam waterproof heat-insulation material permeates into the polyurethane hard foam waterproof heat-insulation material, the aperture ratio of the polyurethane hard foam is increased, the closed aperture ratio is lower than 95%, and the final waterproof heat-insulation performance of the polyurethane hard foam is finally influenced.
The temperature in the ice cold-storage pool is controlled to be above 15 ℃, because the foaming effect of the polyurethane material in the foaming process is greatly influenced by the ambient temperature, when the ambient temperature is lower, a large amount of heat generated in the foaming process of the polyurethane can be transferred to the peripheral wall of the ice cold-storage pool, so that the foaming temperature of the polyurethane is influenced, the final foaming effect is reduced, and the waterproof and heat-insulating performance of the polyurethane hard foam body is influenced.
The polyurethane foam layer is used as the waterproof heat-insulating layer, has a good temperature application range, can play a role in waterproof heat insulation at the ambient temperature of-50-150 ℃, and improves the waterproof heat-insulating durability of the ice cold storage pool at a low temperature for a long time.
Construction of a protective layer: and (3) coating a layer of interface mortar on the foamed polyurethane rigid foam by using a rolling brush or a spraying machine, wherein the dosage of the interface mortar is 50-100 g/square meter. After the interface mortar is completely solidified, spraying an anti-crack mortar layer with the thickness of 2-4mm outside the interface mortar by using a spraying machine, then pressing in an alkali-resistant mesh cloth, spraying an anti-crack mortar layer again, wherein the anti-crack mortar layer is covered with the alkali-resistant mesh cloth, and the total thickness of the anti-crack mortar layer is 6-8 mm. And after the anti-crack mortar is finally set, watering and curing for at least 5 days.
The method directly sprays the polyurethane hard foam waterproof heat-insulation material as the waterproof heat-insulation layer of the ice cold storage pool, and the polyurethane hard foam waterproof heat-insulation material is directly sprayed on the inner side wall of the ice cold storage pool to be rapidly foamed and cured, so that the polyurethane hard foam waterproof heat-insulation material is continuously sprayed for 2-3 times.
Compared with the prior art, the polyurethane hard foam waterproof heat preservation layer is sprayed on the inner side wall of the ice cold storage pool, the waterproof heat preservation characteristic of the polyurethane hard foam waterproof heat preservation layer is utilized, the heat preservation layer and the waterproof layer in the prior art are replaced, direct spraying is formed, construction is convenient, and the period is short.
The invention has the following advantages: 1. the polyurethane hard foam waterproof heat-insulating material is directly sprayed on the inner wall of the ice cold storage pool, so that the polyurethane hard foam waterproof heat-insulating material has strong bonding capability with the inner wall of the ice cold storage pool, avoids the problem that the polyurethane hard foam waterproof heat-insulating material falls off in the later period due to long-term low-temperature environment, and has the advantage of strong durability.
2. According to the traditional method for manufacturing the waterproof coiled material and the heat-insulating plate, a plurality of splicing seams are formed, seams are connected through glue, the glue is easy to age for a long time, and leakage is easy to occur and the heat-insulating performance is easy to influence; this scheme is direct spraying polyurethane hard foam material on the inner wall in ice cold-storage pond, and construction convenience, direct spraying integrated into one piece do not have the concatenation, and the wholeness is good, and waterproof insulation performance is strong, and the durability is strong.
