Ceramic-coated fiberglass member and method for manufacturing the same

摘要

A ceramic-coated fiberglass member and method for manufacturing the same that withstands flames or high temperatures for a substantial period of time. A fiberglass pipe is washed and dried. The pipe is sanded axially along the lengthwise direction of the pipe to expose pores on the pipes. A first ceramic base coating is applied evenly on the pipe. Then, the first ceramic base coating is burnished into the pores. Next, the first ceramic base coating is dried so that substantially no moisture is left in the first ceramic base coating. The first ceramic base coating is axially burnished along the lengthwise direction of the pipe. Then, a second ceramic base coating is applied on the first ceramic base coating. The pipe is dried with first and second ceramic base coatings thereon. The pipe is burnished axially with first and second ceramic base coatings. Subsequently, a first ceramic top coating is applied evenly on the second ceramic base coating. The first ceramic top coating is dried so that substantially no moisture is left in the first ceramic top coating. The first ceramic top coating is burnished axially along the lengthwise direction of the pipe. A second ceramic top coating is applied evenly on the first ceramic top coating. The present invention ceramic-coated fiberglass pipe can withstand 900 degrees F. for over an hour, exceeding the requirement of U.S. Coast Guard (400 degrees F. of open flame for ten minutes) by more than twice.
