What are the advantages of hydrophobic calcium silicate tube shells over ordinary calcium silicate? The core of the hydrophobic calcium silicate tube shell is a special hydrophobic additive added to the ordinary calcium silicate tube shell, and the waterproof and moisture resistance performance is improved through process optimization. Compared with the ordinary version, it has significant advantages in water and moisture resistance, thermal insulation stability, corrosion and frost resistance, and service life, especially suitable for industrial pipeline insulation scenarios with humidity, multiple waters, and high humidity difference;
Simply put, the regular version is only suitable for dry indoor scenes, while the hydrophobic type is a "full scene adaptation". Especially in the rainy and low-temperature climate environment around Zhengzhou and Henan in winter, the hydrophobic calcium silicate pipe shell is used for industrial pipeline insulation, which can fundamentally avoid insulation failure and pipeline damage caused by water absorption and freeze-thaw.
The advantages of hydrophobic calcium silicate tube shell over ordinary calcium silicate are reflected in:
1. Significant improvement in waterproof performance
Hydrophobic calcium silicate tube shell: achieves a hydrophobicity rate of over 98%, effectively preventing water infiltration.
Ordinary calcium silicate pipe shell: high water absorption rate, rapid increase in thermal conductivity after water absorption, decreased insulation performance, and easy cracking due to local water absorption.
2. More extensive application scenarios
Hydrophobic calcium silicate pipe shell: suitable for high water level, high humidity areas and humid environments in the south (such as basements and bathrooms), it can maintain stable performance in these scenarios.
Ordinary calcium silicate pipe shell: Due to poor waterproofing, its application is limited in these scenarios, and additional moisture-proof and rainproof measures need to be taken.
3. Longer service life:
The hydrophobic calcium silicate pipe shell has good waterproof performance and is less prone to cracking, deformation and other problems caused by water absorption, significantly extending its service life.
Ordinary calcium silicate tube shells are prone to performance degradation due to water absorption in humid environments, requiring frequent replacement and high maintenance costs.
