Teknologi Produksi dan Pengembangan dan Penerapan Tabung Fiberglass

Ada tiga jenis utama tabung serat kaca production processes: reciprocating filament winding process, continuous filament winding process and centrifugal casting process.

Proses penggulungan filamen bolak-balik (termasuk metode panjang tetap): Dalam proses ini, tangki pencelupan membalas dengan mandrel yang berputar, dan filamen kaca serat panjang ditempatkan pada sudut miring tertentu relatif terhadap sumbu mandrel, dan sudut bantu (yaitu. Sudut belitan) dikendalikan oleh rasio kecepatan gerak tangki pencelupan dengan kecepatan rotasi mandrel, dan gerakan translasi tangki pencelupan dikendalikan oleh kontrol elektromekanis terkomputerisasi. Jumlah lapisan belitan ditingkatkan secara bertahap sampai ketebalan dinding yang dirancang tercapai. Setelah penggulungan selesai, resin dalam artikel tersebut secara substansial diawetkan. Setelah perawatan, mandrel dikeluarkan dari pipa fiberglass.

Continuous filament winding process (belonging to continuous method): The process is that the tube passes through a feeding station that supplies resin pre-impregnated roving, chopped glass fiber reinforced plastic fiber and resin sand mixture in motion, and the tube is continuously advancing in the core mold. made in.

Centrifugal casting process (belonging to the fixed-length method): In this process, the cut glass fiber reinforced material and sand are fed into a steel mold fixed on the bearing, and the unsaturated resin with catalyst is injected into one end of the steel mold to make the steel mold. It impregnates the reinforcing material. Under the action of centrifugal force, the resin replaces the air in the fibers and fillers, thereby producing a dense composite material without pores. Due to the action of centrifugal force, the inner wall of the tube forms a smooth and clean resin-rich inner surface layer. Cures at higher temperatures. The pipe made by this method is also called glass fiber reinforced plastic sand pipe.
