One, structure of tube wall of glass reinforced plastics of of specification of structure of tube wall of glass reinforced plastics from inside outside arriving, be respectively: Second liner layer, glass reinforced plastics twines layer of liner of glass reinforced plastics, glass reinforced plastics layer, glass reinforced plastics is exterior covering layer. Second liner layer removes layer of liner of glass reinforced plastics, glass reinforced plastics the anticorrosive, action that prevent ooze, twine a layer to load the strength that has conduit and stiffness action, covering layer rises outside fight the ageing, anticorrosion, action that fights insolation. 2, equipment of → of of of preparation of mould of glass reinforced plastics of → of of of of the technological process of conduit of glass reinforced plastics that make is debugged, glass of → of of of solidify of liner of station of the solidify outside Yuan Gong of → of of the of liner of conduit of glass reinforced plastics of → of of raw material preparation that make. It is normal to check equipment movement and working place seriously first, special want careful examination colophony - whether does pump of solidify agent double constituent have jam phenomenon, deserve to ask than whether achieving a design between; Should ensure make line, twine, the moving stability of the equipment such as nap, drawing of patterns and working precision; B, clear mould. Requirement mould surface does not have hole sunken, dust, sundry etc attachment, the mould should make the appearance flowing, the problem is repaired in time, safeguard; C, pester polyester film. For convenient conduit drawing of patterns, fu should be wrapped in mould surface a polyester film, film is built receive width 2 ㎝ of 1 ～ , ply is 40um between. Requirement film does not have damaged, without fold, two sides is smooth and clean. Filmy product quality satisfies the requirement of GB 13950-1992. (2) colophony of A of of of the working procedure that make line, liner is made up. The colophony recipe system that makes according to condition of the working environment at that time, temperature by qualitative check branch undertakes liner colophony matchs add, burden quantity wants a basis to make rate of progress reasonable control. When spot circumstance produces change, qualitative check branch should adjust a recipe in time with production branch, make up the colophony that needs to use by new recipe; B, enhance material preparation. By the design the requirement will make what liner needs to use enhance material to be carried appoint the position, a few righter of wide cut face enhance material to be cut into parts first cut treatment to arrive design width; Layer of C, liner is made. The lay up measure that asks by the design undertakes liner layer make, reasonable tension should bring to bear on in process of each monolayer laid, mutual between right amount build receive, boil repeatedly with assorted pressing roller pressure evict bleb to be soaked in order to make sure fiber is complete. Ask the colophony content that enhances material layer to achieve a design each asks; D, preliminary self check. By the design requirement shop Fu is over each hind, ask jockey person undertakes abecedarian quality detect: Whether does liner achieve design ply, local whether to have the deficient glue, appearance that hang glue, whether to have blaze, bubble, whether to have etc, if happen to afore-mentioned circumstances should be reported in time and take processing step; Working procedure of solidify of the E, deepness outside entering liner Yuan Gong. (3) conduit of glass reinforced plastics of of solidify of the deepness outside Yuan Gong must undertake solidify of the deepness outside Yuan Gong is handled, the purpose is: The solidify that can raise liner layer is spent, improve conduit fight corrupt to be able to bear or endure lukewarm function; (4) of of process quality inspection affirms before twine liner does not have bleb, stoma again, without foreign matter, exterior level off, colophony content is reasonable, without blaze and local solidify undesirable wait for a phenomenon. Must check liner seriously eligible, unqualified forbidden on machine twine. (5) the parameter that twines working procedure to will been designed inputs personal computer, after waiting for liner solidify, by personal computer control is used without alkaline without twist fibre glass undertakes till twine a ply,reciprocating type is twined. Press formulary ply apply of content of 100 ％ colophony outside covering layer. The colophony content that twines a layer is 35 ％ left and right sides commonly, its ply depends on of the intensity that conduit designs and stiffness integrated. (6) conduit of infrared solidify enters solidify conserve phase. Answer to maintain mould scroll with appropriate rotate speed in solidify process, make its even solidify. Monitoring body temperature should note in solidify process, reasonable adjust solidify plan. (7) of nap, drawing of patterns waits for conduit cling to family name hardness is more than 30 when, undertake nap to conduit port. Use machine of hydraulic pressure drawing of patterns to depart conduit and mould next, it is among its conduit the part makes number by the requirement. (8) hydraulic experiment reachs conduit put every batches of conduit have hydraulic test by the regulation, flood water, even step up designs 1.5 times of pressure to conduit, maintain not under 2 minutes, the surface of microscope conduit and pressure are expressed. Try press qualification hind to was propped up at 2 o'clock put pipeline.
