Must know before the decoration: the basic knowledge and precautions

First, the main content of demolition reform

The main contents of the main demolition include the demolition of walls, walls, shovels, removal of heat, replacement of plastic windows, and so on. When the main body is dismantled and reformed, it is to put the framework of the construction site first. If you are an old house here, you still need to do some air-conditioning shifting, so that you can paint later.

Demolition: Demolition (removal of all original renovations), Demolition of walls (demolition of brick walls and concrete walls)

Basic engineering: new masonry wall, brickwork pipeline, wall surface treatment, entrance security door grouting

Second, the main demolition process

Wall treatment: If the original putty is a waterproof putty, you don't need to shovel it. If you don't need a layer of interface agent, you will need to scrape and put it again. If not, all shovel it out and do it again. Putty scraping 2-3 times on it. In places where the walls are grooved, they should be sealed with plaster, affixed with real kraft paper (pulled continuously), and then puttyed. Empty drums or cracks must be handled.

Third, the premise of the main demolition reform

If the situation is too much or too small, the main structure of the house must be reformed again, because too much or too little space is unscientific, it is not conducive to living, and it is necessary for some unnecessary partitions. Demolition will make the entire structure more comfortable and reasonable.

Fourth, the details of the main demolition reform

The purpose of the demolition of the main body is to make the space more practical, but it must be cleared out of the garbage after the demolition and renovation. This will not only ensure the cleanliness of the interior, but also facilitate the construction. After the main body is demolished, the finished door can be determined, and cabinets, hoods, stoves, and water heaters can also be determined together.

V. Precautions for demolition of the main body

When the main body is dismantled and reformed, it is to put the framework of the construction site first. Everyone must pay attention to this construction:

1. The load-bearing wall must not move, and even one hole should not be opened.

2. Before the hydropower reform, the transformation of the main body is basically completed.

DUPLEX STAINLESS STEEL

Duplex Stainless Steels Available

Yuhong Group supplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.


Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.


Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
