Description
Technical field
The invention belongs to glass fibre or basalt fibre sample detection technical field, particularly the characterizing method of a kind of glass fibre or basalt fibre cross-sectional morphology and size.
Background technology
The filament diameter of glass fibre or basalt fibre precursor is one of key index of controlling fibre property, and the size of filament diameter is one of factor affected the fiber property indices.In Fibre sorting, often according to the difference of fibre diameter, number and number of share of stock, fiber is carried out to class indication.
The xsect of simple glass fiber or basalt fibre is circular, and, for profile fibre, its xsect has the shapes such as ellipse, silk cocoon shape and hollow shape, and the control to profile fibre cross-sectional morphology and size in production run is very important.So, the sign of general fibre or profile fibre cross-sectional morphology and size is just seemed to very necessary.
At present, mainly containing transmission microscopy, projector method, scanning electron microscope detection method, capacitance method and transmission interferometric method for the means of glass fiber single filament diameter measurement detects online.
For transmission microscopy and projector method, key step is to have got on request sample before test, then sample is placed on clean microslide, by suitable method, fiber dispersion is opened, place it in again observed reading on transmission microscopy or projector objective table, finally will, the lattice number that every fibre diameter occupies is converted into the micron number of fiber.Adopt the method to measure the glass diameter, be the glass fibre length direction by microscopical transmitted light or projector imaging, can't be when measuring micro-diameter sign fiber cross section pattern; Due to the monofilament in fibrous bundle not at grade, have larger error by measuring its diameter after transmission or projection imaging.
Adopt scanning electron microscope both can be characterized the fiber cross section pattern, can be measured fiber cross sectional dimension again, be a kind of desirable checkout equipment simultaneously.But scanning electron Electronic Speculum expensive (a set of equipment needs 1,000,000 Renminbi left and right), maintenance cost is high, seldom this equipment of unit or enterprise configuration; Professional knowledge, technical ability to the operation and maintenance personnel of equipment are had relatively high expectations; Entrust submitted sample if adopt, its testing cost is higher again.
The online detection fibers diameter of capacitance method and transmission interferometric method.Transmission interferometry principle is: while utilizing the He-Ne Ear Mucosa Treated by He Ne Laser Irradiation quartz fibre that wavelength is 0.6328 micron, penetrate after the quartz fibre right cylinder a part of light that is refracted to get on toward all directions; Another part light got on toward all directions with the reflection of quartz fibre periphery produces interference; The interference fringe of semicircular, the regular arrangement of stroke in the quartz fibre dead ahead, make the size of quartz fibre diameter from the interference fringe interval width.Adopt this two kinds of methods: the pick-up unit complexity, the equipment investment expense is high; Professional skill requirement to the technician is high, and general personnel are difficult for grasping; When can't both be characterized the fiber cross section pattern, fibre diameter was measured; And being mainly used in the fiber drawing workshop detects online.
