It is easy to operate and widely used. The use of this product can significantly accelerate project progress and improve work quality in equipment installation and reinforcement construction. Within a few hours after pouring, it is safe for pedestrians and traffic, reaches the designed service strength, allowing for equipment installation and operation, thus enabling early production start or production recovery.

Sika Grouting Material Drying Shrinkage Leak Cause Analysis:
Despite varying opinions among scholars on the details of the drying shrinkage mechanism of grouting materials, there is still no unified and entirely satisfactory explanation. However, after years of research, it is generally agreed that the main cause of shrinkage in hardened cement is the evaporation and loss of water from capillary and gel pores in grouting materials. In other words, drying shrinkage causes water loss from capillary pores in the hardened paste, leading to the formation of concave liquid surfaces and creating a pressure difference P between the inside and outside of the capillary walls. The larger the P, the greater the drying shrinkage. The factors affecting P and their relationships are described by the Young-Laplace equation.
Thus, for grouting materials with the same amount of binder, water-to-binder ratio, fluidity, and environment, the drying shrinkage depends on the surface tension of the liquid in the capillary pores of the grouting material, the contact angle between the liquid and the capillary wall, and the radius of the capillary pores.

The development of high-strength cement grouting material technology has played a significant role in the advancement of reinforcement and renovation industries. In recent years, the strength of cement grouting materials has been continuously improving, reflecting the ongoing enhancement of the grouting material industry and promoting the development of the reinforcement and renovation sector. However, in the application and promotion of cement grouting materials, it has not reached the ideal level: some manufacturers always think that using more cement will benefit the quality of the grouting material, which is actually a very incorrect practice.

Introduction to Sikal浆料
Sika Grout and Epoxy Grout offer zero shrinkage, excellent fluidity, and rapid strength gain (with compressive strength up to 55 MPa), and high long-term strength (compressive strength up to 85 MPa, with epoxy grout reaching up to 90 MPa). They are suitable for the installation and anchoring of large equipment in paper mills, power plants, and mechanical and electrical production companies, and are used by companies like Sinopec Paper, Yinsun Energy, Guangzhou Paper Mill, Chenming Paper Industry, Sun Paper Industry, and Rimguo Paper Mill. The brand's construction helps differentiate products from others and adds more value. As early as the founder Kaspar Winkler realized the importance, it was his foresight that led to naming the company Sika and designing its logo. Sika has stood the test of time, a tribute to the founder's vision. Sika has consistently used the original logo design, only making minor adjustments. Globally, the Sika logo represents innovation, quality, and service. Over the decades of Sika Group's expansion, the Sika brand has become a highly valuable asset. The word "Sika" and its alternating red and yellow logo have become deeply rooted in the global market.
Ningbo Bofang Wind Power Technology Co., Ltd. combines direct sales with distribution. The primary focus is on establishing a national distribution network for sales, with direct sales mainly targeting key clients and global procurement order clients, as well as clients within Guangdong Province. Distribution network sales serve as a supplement, with out-of-province clients primarily relying on the national distribution network. The company has established numerous distribution outlets across the country, forming a national sales network that can provide comprehensive production and service support to meet various customer requirements.
