Plastic floor installation requirements
1.1 The ground is required to be flat, and the ground drop should not exceed 3mm per meter. When it exceeds, use quick-drying powder or cement to level it;
1.2 The ground must be dry;
1.3 The time for the floor to enter the construction site is relatively cold. The floor should be installed at the construction site. The entire package should be stored for more than 48 hours. It can be installed after being adapted to the temperature and humidity difference. Otherwise, the floor may be easily deformed.
1.4 Treatment of related parts of plastic flooring For door pockets, heating hoods and all irregularities that require special treatment, the construction approval must be sought from the user before installation, and construction must be signed before signing the construction sheet.
1.5 Cross construction is strictly prohibited on site.

2.1 Preparation stage: If the model and quantity of the product are checked, a wood wedge is fixed in the baseboard hole, the floor is cleaned, and a floor mat for HONGJI is laid;
2.2 The installation phase: pay attention to the direction of paste, glue curing time, assembly methods, especially the first row, the last row and special parts of the treatment;
2.3 Installation of baseboards and buckles;
2.4 Finishing work: ground cleaning, quality inspection, recycling of residual materials, etc.
Plastic floor installation precautions
3.1 The scope of use of glue: pay attention to the glue area, the amount of glue, extrusion method, post-dry treatment, etc.;
3.2 expansion joint provisions: between the floor and the contact surface (object) (such as walls, door covers, heating covers, water pipes around) must leave enough expansion joints, as long as the door must be installed buckle;
The geothermal installation of plastic flooring must be done in accordance with appropriate standards. The ground conditions and geothermal temperature must meet the geothermal installation standards. It is forbidden to use ordinary ground methods for installation.

2. Make the specimen relatively fixed;
3. It is convenient to use the capillary phenomenon to form a gradient when adding various reagents (staining agent, acid, salt solution);
4. Avoid contamination of the specimen.

The cover glass is covered on the material on the glass slide, which can avoid the contact between the liquid and the objective lens, so as not to contaminate the lens, and can make the top of the observed cells in the same plane, that is, the distance from the objective lens is the same, so that the observed Images are clearer.Why do you need a coverslip when using a microscope
1. Make the object to be observed form a thin film, which is easy to transmit light and easy to observe;2. Make the specimen relatively fixed;
3. It is convenient to use the capillary phenomenon to form a gradient when adding various reagents (staining agent, acid, salt solution);
4. Avoid contamination of the specimen.
The purpose of staining the specimen with iodine solution is to make the cells more obvious under the microscope, and it can also kill the cells and prevent the cells from migrating.
