Ship cabin coating method

Abstract

The invention discloses a ship cabin coating method. The method includes the steps that the total spraying amount and maximum spraying planning time of spraying oil paint and diluent needed by a cabinare confirmed; the minimum spraying amount required in unit time is acquired according to the total spraying amount and the maximum spraying planning time; the specifications of spray guns are selected, the number of the spray guns which operate at the same time is set, and the prediction spraying amount of all the set spray guns in unit time is calculated, so that the prediction spraying amountis larger than the minimum spraying amount; the minimum ventilation rate in unit time is worked out according to the prediction spraying amount, diluent type and organic solvent poisoning prevention planning value; the draught fan type is selected, the number of draught fans is set, and the prediction ventilation rate of the set draught fans in unit time is made to be larger than the minimum ventilation rate; and spraying is conducted after the draught fans are arranged. The ship cabin coating method has the beneficial effect that a ventilation rate calculation method which is more suitable for the field actual needs is formulated before spraying in accordance with the actual spraying portions, spraying paint and actual spray gun number.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a method for painting a ship cabin. Background technique [0002] From the perspective of the ship structure, the ship is composed of various ballast tanks, oil tanks, fresh water tanks, fuel tanks, empty spaces and other confined spaces from the beginning to the end, from top to bottom. It must be painted and sprayed, which is very easy to create a toxic, harmful, flammable and explosive working environment. At the same time, there are cross-operations between cabins and processes in the shipbuilding process, and inert gases such as CO and H2S are trapped in the cabins. Slight negligence or violation of regulations may lead to safety fatal accidents such as explosion or poisoning, resulting in casualties and property losses. Therefore, in view of the different working conditions of the closed cabins in the on-site construction during the ship coating construct...

[0002] From the perspective of the ship structure, the ship is composed of various ballast tanks, oil tanks, fresh water tanks, fuel tanks, empty spaces and other confined spaces from the beginning to the end, from top to bottom. It must be painted and sprayed, which is very easy to create a toxic, harmful, flammable and explosive working environment. At the same time, there are inter-compartment operations in the space between cabins and processes in the shipbuilding process, and inert gases such as CO and H2S are trapped in the cabin. Slight negligence or violation of regulations may lead to safety fatal accidents such as explosion or poisoning, resulting in casualties and property losses
