Description
Technical Field
The invention relates to the technical field of carbon fiber sizing, in particular to a fiber sizing assembly line for tests and a sizing process thereof.
Background
The continuous silicon nitride fiber and the silicon carbide fiber have the excellent characteristics of high strength, high modulus, high temperature resistance, ablation resistance, chemical corrosion resistance, good high-temperature stability and the like, and belong to the national strategic special ceramic materials. Sizing is an essential procedure in the manufacture of such fibers. Silicon nitride and silicon carbide fibers are similar to carbon fibers and glass fibers, so the sizing equipment and the sizing process mainly refer to the sizing process of the carbon fibers, the glass fibers and the like. However, the surface properties of silicon nitride fibers and silicon carbide fibers are greatly different from those of carbon fibers, glass fibers, and the like. Such as silicon carbide fibers consisting essentially of beta-SiC, SiC x O y Free carbon, SiO 2 And a small amount of SiC x O y N z The silicon nitride fiber is amorphous and mainly composed of SiN 4 Structural element and SiN x O y Phase composition, only trace carbon element exists. And the carbon fiber consists of an inert graphite layer structure, and only contains C, N, O elements. The difference of surface elements of different fibers causes the fibers to have different wettability and physical bonding property to sizing agent. Compared with carbon fiber reinforced composite materials, the silicon carbide fiber and the silicon nitride fiber have higher service temperature and stricter requirements on fiber composition. Alkali metal ions, oxygen elements, carbon elements and the like in the sizing agent used in the sizing process have great influence on the high-temperature resistance of the fibers, so the content of the alkali metal ions, the oxygen elements, the carbon elements and the like in the sizing agent is strictly controlled in the sizing process of the fibers. In summary, the continuous silicon carbide fiber and the silicon nitride fiber should use proper sizing agent to meet the requirements of fiber application and weaving performance。
In the development process of the sizing agent, the performance test of the sizing agent is required, and the test of parameters such as solid content, surface tension, viscosity, centrifugal stability and the like is mainly carried out. The fibers after sizing are also required to be tested, and mainly comprise the tests of contact angle, abrasion resistance, wool amount, sizing rate, tensile strength and the like. It can be seen that the application of the sizing agent to the above-mentioned fiber in the preliminary pre-research test requires a large amount of fiber consumption, the test period is long, and if the developed sizing agent is tried directly on the production line, the following problems still exist: firstly, production needs to be stopped, and the orthogonal test process of the sizing agent requires repeated replacement of the sizing agent, so that the sizing tank is frequently replaced, disassembled and cleaned, and the cost is high; secondly, the sizing equipment of the production line is used for sizing fibers, the needed fibers are relatively long (more than or equal to 10m), and the abrasion of the rollers, the wire releasing and the wire collecting processes to the fibers is large in the sizing process, so that the testing performance of the fibers is influenced.

step 1, firstly detaching the silica gel plates at two ends of a slurry dipping tank, holding two ends of fibers by hands to keep the fibers in a stretched state, putting the fibers into the slurry dipping tank containing a sizing agent, and dipping for 5-10 s;
step 2, enabling the fibers to penetrate through two slurry scraping sheets of a slurry scraping device along the horizontal direction, scraping slurry, and enabling the scraped sizing agent to drip into a recovery tank;
and 3, finally cutting the fiber subjected to pulp scraping into a proper length, fixing the fiber on an oven plate, drying the fiber in an oven at the temperature of 120-200 ℃, and taking out the fiber.
7. A process for sizing test fibers according to claim 6, wherein: the fibers are continuous silicon nitride fibers.
8. A test fiber sizing process performed using a test fiber sizing line according to claim 1, characterized by: the method comprises the following steps:
step 1, installing silica gel plates at two ends of a slurry dipping tank, then holding one end of a fiber wound on a roller by hand to keep the fiber in a stretched state, feeding the fiber in the slurry dipping tank at a speed of 2-4 cm/s, passing the fiber impregnated with a sizing agent through a silica gel sheet, performing primary slurry scraping, and leaving the sizing agent scraped from the fiber in the slurry dipping tank;
step 2, continuously drawing the fibers to penetrate through two pulp scraping sheets of the pulp scraping device along the horizontal direction, performing secondary pulp scraping, and dripping the scraped sizing agent into a recovery tank;
and 3, finally cutting the fiber subjected to secondary pulp scraping into a proper length, fixing the fiber on an oven plate, drying the fiber in an oven at the temperature of 120-200 ℃, and taking out the fiber.
9. A process for sizing test fibers according to claim 8, wherein: the fibers are continuous silicon carbide fibers.
