Some technical processes typical of Green Zone

1. The process of painting the wall surface and the cement matrix:

1.1. Survey, assess surface

 For technicians cement floor, technician make report setting out the situation with the following contents:

  •     Check the thickness of the floor.
  •     Check the flatness of the floor.
  •     Gradient mesh is reinforced or cracking it?
  •     Waterproofing extent?
  •     Cement ratio of cement mortar?
  •     Other additives in Ciment.
  •     The time of construction? (Minimum 28 days)
  •     Floor have carefully sealed bottom yet?
  •     The purpose of the use after application (the factory, the assembly plant, the storage, the clean room)
  •     For wall-technical personnel assess the current state record with the following report:
  •     Check plastered surface.
  •     Check the surface location construction for proper construction plans.
  •     Time for Wall construction

1.2. Prepare construction plans and advice to customers:

Based on the results of the assessment of the condition prior to construction, technical staff of GreenZone will consider and consult on customer requests for work (color, gloss, use ... ). On that basis, GreenZone will advise customers and uniform execution of the plan and use appropriate chemicals for the quality and price to ensure work quality according to the requirements and objectives use and reduce costs by using the wrong materials or avoid the use of expensive materials are not needed.


1.3. Execution and supervision of paint:

After construction plans have been agreed with the customer, the team construction and construction supervision will be organized to implement the construction stage: Tra close to the surface, paint, surface coating, finishing , and the cleaning of the surface of the refund to the customer according to the requirements of the contract signed.

During the construction process, the customer will confirm the job has been completed according to the construction plan was agreed. Execution Plan will include the following basic tasks:

  • Clean the surface and the concave blade repair the bad part, the wall, ...
  • Surface primer.
  • Surface coatings.
  • Cleaning and refund synthetic surface, ground works for customers
  • Also, GreenZone must comply with the instructions of the paint manufacturer to ensure quality paint work.


1.4. Commissioning works:

After GreenZone completed and works hand over and fulfill the warranty procedure in the signed contract, the customer will test record collection and disposal works contracts.


2. Cleaning procedures, cleaning buildings, factories,.

2.1. Survey, assess the entire factory area;

• Investigation of floor surface: factory floor material (cement, wood, carpet ...). Survey area restrooms, stairs, wood doors, glass doors, high use areas (pipes, air conditioners, fans, ..)

• Catalog your work need cleaning, cleaning buildings within the customer's request.

• Checking for dirty / clean surface materials (cement, glue, paint, grease, ....) to select the type of cleaning chemicals in accordance with the materials ....

2.2. Prepare construction plans and advice to customers:

Based on the results of the evaluation workshop status before making sanitation, clean, GreenZone technical staff will exchange, consultation and agreement with the client on the construction plans to ensure quality according to the amount of work required and does not affect the production of client:

• Catalog your work need cleaning, cleaning buildings within the customer's request.

• Selection of equipment, construction of appropriate tools.

• Calculate the number of employees.

• Use the proper cleaning chemicals.

• Date and time of construction.

2.3. Implementation of the plan:

After construction plans have been agreed with the customer, the team construction and supervision of the organization GreenZone will implement the construction stage. During the construction process, customers need to modify or supplement the content of work, the construction project will be recalculated or added. New construction plan will be agreed with the client.

2.4. Commissioning works:
After GreenZone completed and works hand over and fulfill the warranty procedure in the signed contract, the customer will test record collection and disposal works contracts.


3. The process of cleaning, spraying insecticide houses, offices, factories, buildings, and hotels.

3.1 Survey:

• Survey and check each area: office, toilets, stairs, floors, walls, ceilings, corners, hidden places inside, outside, trees, lawn, drain , water storage tanks ...

• Measure the area of ​​the floor to the price, the greater the area of ​​declining prices.

3.2 Preparation equations frequently employed approach:

According to the survey results, the technical staff will GreenZone ¬ advice and investment agreement with the client spraying plans to ensure quality drinking ¬ l as requested, and do not damage the photo ¬ he came to the production of customers:

• Selection of drugs and drug use.

• Check spray, spraying machines to avoid malfunctioning in the construction process.

• Calculate the number of drink;

• Date and time of construction.


Perform ¬ 3.3 ph level spraying project:

After construction plans have been agreed with the customer, the spraying will take steps in accordance with the spray: cover equipment assets such as furniture, bed cabinets, computers, pictures ..., indoor spraying out from the house, clean the floors, doors, shelves ... after spraying customers.
Spraying process will include the following basic steps:

+ Spray disinfectant in the home:

- The hidden area (behind the door, corner, corner cabinets)

- Toilet, kitchen, canteen ...

- Classrooms, dormitories, hallways, stairs.

+ Original spray oil outside the building, such as trees, shrubs, garbage, sewer, ditch

+ Clean up after spraying doors, shelves, tables, chairs, furniture, office equipment.

To achieve high performance, then you should be sprayed periodically from 1 to 3 months / time (depending on the environment where spraying)

Advice on materials used in industrial hygiene

Through much of the actual construction process, the technical staff of GreenZone draw some comment about the material, chemical equipment and tools used in the work of sanitation in Vietnam as follows:

Building materials and various types from various sources. Specifically: sawn stone, polished granite or of lumpy, marble, tiles, ceramic tiles, porcelain, brick red (brick floor well ...), wood flooring, natural wood flooring and industrial flooring / vinyl wallpaper, wall Simily, carpets, plastics and composite compounds, gypsum, glass, aluminum, stainless steel, brass, iron, cast iron ..

To use sustainable, we need the chemicals, equipment and tools used to meet the characteristics of each type of material. Currently, manufacturers of detergents and treatment from diverse elements, in order to ensure quality of work life and keep the material of material going into expertise was launched by the specialized chemicals for each category with different levels of use of the:

  • Cleaning Materials
  • Removing grease stains, yellow stains
  • How bright color materials
  • Waterproof or water resistant suction
  • Hold your breath level of construction materials to ensure hygiene in daily life
  • Negative surface protection materials
  • Create color material, restore the natural color of the material
  • Anti-breakage of brittle material (especially sawn stone, granite).
  • Anti-mildew and weathering
  • Anti influence backlog due to the chemical reaction continues in the material can cause damage to the material. For example, rainfall in the city axid on long natural stone materials from corrosion, faint, or have been roughened to create fissures in the limestone rock by the corroded fibers
  • The chemicals prior to paving stones lined to prevent leaching problems pigments (metal base) from the floor or the wall.

We found that the Industrial Hygiene not merely wiping clean that it requires workers need specialized skills to know how to properly use technical expertise. This requires workers to be trained in technical expertise.

Since in many practical projects, we find that the industrial sanitation workers need basic knowledge about the use of chemical cleaners to avoid misuse, prone to disastrous consequences for the material. For example, chemicals used to clean the axid sawn stone or marble to calcium cause concave surface corrosion, pitting, loss of gloss, the circuit is broken cement and waterproof floor. So we need to pay attention with the chemicals used for this material but can not be used for other materials.
