Problems solved by technology

However, the technical solution does not describe the specific composition of the lightweight filler and its specific performance requirements, and different materials have different properties, prices and production processes, and the technical solution alone cannot solve the problem of shipbuilding. The technical problem of easy water ingress makes it impossible to apply it industrially

Embodiment 1

[0044] 100kg of flame-retardant expandable polystyrene (EPS, product brand: Longwang brand, specification F-SB) was pre-foamed on a Japanese DAISEN DYHL500 batch foaming machine, and the pre-foaming steam pressure was 0.025Mpa. Feeding 7kg per batch, heating time 35s, pre-expansion density 20kg / m 3 , EPS particles are formed after foaming; then the foamed EPS particles are transported into a silo made of nylon mesh bags by a windmill, and after curing at room temperature for 8 hours, they are molded by K1214 molding machine produced by German KURTZ company. The size of the model is 500*500*300mm, the steam pressure of the fixed mold is 0.08Mpa during molding, the steam pressure of moving mold is 0.1Mpa, the total heating time is 18s, water cooling is 10s, vacuum cooling is 80s, and the molding cycle is 160s; EPS obtained after molding After the foam board is dried in a drying room at 65°C, the EPS foam filling of the desired size and shape can be obtained, which can be directl...

[0046] 100kg of flame-retardant expandable polystyrene (product brand: Longwang brand, specification F-SB) was sold in DAISEN, Japan

[0047] Foaming is carried out on the DYHL500 batch foaming machine, the pre-foaming steam pressure is 0.025Mpa, the feeding material is 7kg per batch, the heating time is 35s, and the pre-foaming density is 20kg / m 3After foaming, EPS particles are formed; then the foamed EPS particles are transported into a silo made of nylon mesh bags by a windmill, and after curing at room temperature for 8 hours, they are molded with a PSZ6000 sheet machine produced by Hangzhou Fangyuan Company Forming, the size of the plate is 6000*1200*650mm, the steam pressure of the solid mold is 0.06Mpa during forming, the steam pressure of the moving mold is 0.08Mpa, the total heating time is 25s, the exhaust is 10s, the vacuum cooling is 250s, and the molding cycle is 380s. After the formed EPS foam board is dried in a drying room at 65°C, it is cut into EPS foam fill...

Embodiment 3

[0049] 100kg of flame-retardant expandable polystyrene (product brand: Longwang brand, specification F-SB) is foamed on a Japanese DAISENDYHL500 batch foaming machine, the pre-foaming steam pressure is 0.035Mpa, and 10.5kg is fed per batch times, the heating time is 55s, and the pre-expansion density is 30kg / m 3 After foaming, EPS particles are formed; then the foamed EPS particles are transported into a silo made of nylon mesh bags by a windmill, and after curing at room temperature for 9 hours, they are molded with a PSZ6000 sheet machine produced by Hangzhou Fangyuan Company Forming, the size of the plate is 6000*1200*650mm, the steam pressure of the solid mold is 0.06Mpa during forming, the steam pressure of the moving mold is 0.08Mpa, the total heating time is 18s, the exhaust is 10s, the vacuum cooling is 400s, and the molding cycle is 560s. After the formed EPS foam board is dried in a drying room at 65°C, it is cut into EPS foam fillers with a size of 500*500*500 by us...

Abstract

The invention relates to the technical field of shipbuilding, in particular to a method for making a ship cabin difficult to enter water and a hull for making the ship cabin difficult to enter water. The non-toxic polystyrene foam filler is light in weight and not easy to absorb water. Therefore, when the ship cabin is broken or the ship encounters an accident, the foam filler in the ship cabin is not easy to enter the water, which will not cause the hull to sink, thereby strengthening the ship. safety performance.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for making a ship warehouse difficult to enter water and a hull for making the ship chamber difficult to enter water. Background technique [0002] On April 15, 1912, the luxury ship "Titanic" carrying 1,316 passengers and 891 crew members collided with an iceberg and sank. This shipwreck is considered one of the top ten disasters in the 20th century. [0003] Before the 20th century, how many similar tragedies happened in the long history of human society, and the occurrence of such tragedies has a certain relationship with the development of shipbuilding science and technology at that time. Because the ship hulls built at that time had mostly empty cabin structures, in case of accidents (such as hull rupture, hull contact, ship collision, etc.), water would often leak into the cabin, causing the hull to sink and capsize. Or a sinking accident. [0004] In order ...
