FRP profile ebbaala eyeetooloovu .
FRP profile round bar ye kika kya FRP okusika profile efulumiziddwa, ebitera okulaga bye bino φ 5, φ 6, φ 7, φ 8, φ 10, φ 12, φ 16, φ 18, φ 20, φ 30 n’ebirala.
Pull extrusion molding process ye nkola ey’enjawulo mu nkola y’okubumba FRP, esaanira okukola ebifaananyi bya FRP eby’enjawulo, gamba nga emiggo, payipu, ebifaananyi ebigumu (ekikula ky’omulimu, groove, square profiles) n’ebifaananyi by’okusiiba. Ebirungi byayo bye bino:
1, enkola y’okufulumya eri mu maaso, omutindo gw’ebintu ogutebenkedde, okuddiŋŋana okulungi;
2. Ebirimu ebikozesebwa ebinywezeddwa bisobola okutereezebwa okusinziira ku byetaago, era amaanyi g’ekintu gali waggulu;
3. okusobola okutereeza amaanyi ag’obuwanvu n’amaanyi ag’obuwanvu bw’ekintu okutuukiriza ebyetaago eby’enjawulo eby’okukozesa;
4. okusobola okufulumya ebintu ebirina enkula y’ekitundu ekizibu okutuukiriza ebisaanyizo by’emikolo egy’enjawulo;
5, ebintu birina obutuukirivu obulungi, omuwendo gw’okukozesa ebigimusa mungi;
Omuwendo gw’ensimbi eziteekebwa mu byuma bitono.
Ebikozesebwa ebisookerwako ebikozesebwa mu kukuba ebifaananyi n’okufulumya .
1. Matrix ya resin .
Mu nkola y’okusika n’okusika, esinga okukozesebwa ye resin ya poliyesita ezitajjudde, epoxy resin, vinyl resin, thermosetting methacrylic resin, modified phenolic resin, flame retardant resin n’ebirala.
(1) Polyester resin etajjudde .
Ekozesebwa ku kusika okusinga ye benzene ne benzene. Benbenzene resin alina ebyuma ebirungi, obugumu, okuziyiza ebbugumu n’okuziyiza okukulukuta. Mu kiseera kino, enkozesa y’awaka ey’ekika kya benzene, kubanga bbeeyi yaayo esinga ekika kya benzene, naye omutindo olw’ekituli ekinene eky’abakola ebintu eby’enjawulo, enkozesa erina okulondebwa n’obwegendereza okusinziira ku bintu eby’enjawulo.
(2) Vinyl resin vinyl resin erina omulimu omulungi ogw’enjawulo, esobola okulongoosa obuziyiza bw’eddagala n’okunyweza amazzi.
(3) Epoxy resin .
Okugerageranya ne unsaturated polyester resin ne phenolic resin, epoxy resin erina ebyuma ebirungi ennyo, eby’obusannyalazo ebingi, okuziyiza okukulukuta kw’okungulu n’okuziyiza arc, era nga kintu kirungi nnyo eky’okuziyiza omusana.
(4) Ekirungo kya phenolic resin .
Ye kiraasi eyasooka eya resin ya thermosetting. Nga zirina obuziyiza obw’amaanyi obw’amaanyi obw’amaanyi obw’ekiseera ekiwanvu, ekirungo kya phenolic resin kibadde kikozesebwa bulungi mu nkola.
2. Okwongera ku bikozesebwa .
Ebintu ebinywezeddwa ebikozesebwa mu nkola y’okusika n’okusika okusinga biba fiber y’endabirwamu n’ebintu byayo, nga untwist roving, glass fiber felt, etc. okusobola okutuukiriza ebyetaago eby’enjawulo eby’omutindo gw’ebintu, aramid fiber, carbon fiber, ultra{1}}high molecular weight polyethylene fiber ne basalt fiber bisobola okukozesebwa.
(1) Omuguwa gw’endabirwamu .
Omuguwa gw’endabirwamu ogukozesebwa okusika n’okusika okusinga tegulina alkali, alkali ya wakati n’obuwuzi bw’endabirwamu obw’amaanyi amangi.
Ebika by’ebintu ebikolebwa mu ndabirwamu bye bino:
1 ROVING .
Waliwo obuwuzi obukwatagana n’obuwuzi obutereevu nga buliko layini ya 1100 (1200) okutuuka ku 4400 (4800). Ebyetaagisa: Okutondebwa okulungi; okukendeera okulungi; Okusika omuguwa mu ngeri y’emu; density ya layini emu; Okuyingira okulungi.
2 Ekipande kya fiberglass felt .
Short Cut Felt Requirements: Omutindo gw’ekitundu ogw’enjawulo; okugabanya kwa waya ennyimpi ezisala n’ekirungo kya C ekyesiiga ekifaanagana; amaanyi g’okuwulira okw’ekigero aga dry felt; Okuyingira okulungi ennyo. ku bintu ebyetaagisa amaanyi nga tebiri waggulu nnyo.
Continuous felt enyweza effect ennungi okusinga short cut felt. Saba kye kimu nga waggulu.
Surface felt ekola ku kukyusa ku ngulu n’okuziyiza asidi.
Suture Felt terimu binder, performance nnungi ennyika, ate nga ya bbeeyi ntono.
3 Olugoye lw’omusono gw’ebiwuzi by’endabirwamu lusobola okwongera ku maanyi g’okusika n’amaanyi g’okubeebalama ag’ekintu; okukendeeza ku buzito bw’ekintu; Smooth ate nga kiweweevu kungulu.
4 combined glass fiber reinforced material, esobola okutereeza amaanyi g’ekintu ekyo mu bbali n’obuwanvu.
(2) Omuguwa gwa kaboni .
Uused for high strength, obuzito obutono, okutwalira awamu ne vinyl ne epoxy resin.
