Cold storage spray polyurethane focuses on the overall seamless condition after spray foaming. Polyurethane has good density, insulation and cold resistance. It is basically a closed cell structure. It not only has excellent thermal insulation properties, but also has good resistance to freezing and thawing and sound absorption.
Polyurethane silo panels are silo panels produced in silo panel factory. The thermal insulation material is polyurethane, and the panel is color steel, stainless steel, embossed aluminum, etc., and then pulled to the construction site for assembly.
Cold storage assembled with polyurethane cold storage board is generally called combined cold storage. Combined cold storage is also known as mobile cold storage, combined cold storage, combined cold storage. Most of them are in single-story form.
It can be analyzed from the following points:
1, cost: the cost of cold storage board is relatively high, and the cost of spraying is relatively low;
2, the use of the process: cold storage board relocation is convenient, spraying can not be relocated.
3, in terms of the use of places: can be made of steel sheds, civil construction of housing
Warehouse board is expensive, can be disassembled and moved later. Spraying insulation effect is better than warehouse board, low cost, not removable.
From the point of view of insulation analysis, cold storage spray polyurethane insulation will be better, sealing performance will be better. Especially for large civil structures, most of them are sprayed polyurethane on site, which is cheaper than barn board. Higher space utilization. Can do multiple layers. But the weight of the polyurethane warehouse board is limited and can only do one layer. But in terms of aesthetics, the warehouse board will be slightly better.
1, it depends on how big cold storage you want to build. If the storage space is small, please use polyurethane storage board. Very few spray masters with small storage areas are willing to do it.
2, It depends on whether you are working out of your own home or renting. How long is the rent? Spray bins are not removable and low cost, urethane panels are removable and high cost. If you own your home, see if you need to move later and choose an economical option based on longevity!
Polyurethane elastomers are typical multi-block copolymers, where the molecular chain consists of flexible chain segments with a glass transition temperature below room temperature and rigid chain segments with a glass transition temperature above room temperature. The oligomer polyol constitutes th

In order to select the shrinkage rate of large cast polyurethane elastomer products more accurately, the influences of process conditions, environmental factors and product structure on the shrinkage rate were systematically investigated, and the change curves of shrinkage rate with time were measur

For the polyurea spraying equipment should take how to recommend1, polyurea is a set of waterproof, anticorrosion, wear-resistant, protection of multiple performance materials, but there is a certain range of tolerance, polyurea's recommended temperature range for the use of -40 ℃ -120 ℃.2、 Polyurea
Polyurea waterproof and anti-corrosion construction is generally spraying operation, in front of the small series to tell you why the reason for spraying, I believe everyone should have understood, now is about the construction process of the problem, let's take a look at it.Summary of polyurea wate
One. Corrosion resistanceIn addition to hydrogen acid, concentrated nitric acid and some strong oxidants, polyurea coatings show good stability in acid, alkali, salt, seawater, oil and other media, in the salt spray medium to do a strengthening comparative experiment, 1000 hours later, polyurea and
1. Increase efficiencyThere's a reason operators don't like manual mixing. It's a repetitive, physically demanding, and inefficient job. This includes manual heating and mixing of elements, trying to guess the correct dosage and loading the mixed paint into the spray system. It's becoming increasing
