Ibikoresho bishimangira nigikanka gishyigikira ibicuruzwa bya FRP, bigena ahanini imiterere yubukorikori bwibicuruzwa bya pultruded. Gukoresha ibikoresho bishimangira kandi bigira ingaruka runaka mukugabanya kugabanuka kwibicuruzwa no kongera ubushyuhe bwimiterere yubushyuhe hamwe nubushyuhe buke bwubushyuhe.

Mugushushanya ibicuruzwa bya FRP, guhitamo ibikoresho bishimangira bigomba gutekereza byimazeyo uburyo bwo kubumba ibicuruzwa, kubera ko ubwoko, uburyo bwo gushyira hamwe nibirimo ibikoresho bishimangira bigira uruhare runini mubikorwa byibicuruzwa bya FRP, kandi ahanini bagena ubukanishi imbaraga na modulike modulus yibicuruzwa bya FRP. Imikorere yibicuruzwa byifashishije ibikoresho bitandukanye byubaka nabyo biratandukanye.

Mubyongeyeho, mugihe wujuje ibyangombwa bisabwa mubikorwa byububiko, ikiguzi nacyo kigomba gutekerezwa, kandi ibikoresho bishimangira imbaraga bigomba guhitamo byinshi bishoboka. Mubisanzwe, kudatoragura kugendesha ibirahuri bya fibre biri munsi yikiguzi kuruta imyenda ya fibre; igiciro cyaibirahuri bya fibreni munsi yumwenda, kandi kudahinduka ni byiza. , ariko imbaraga ni nke; fibre ya alkali ihendutse kuruta fibre idafite alkali, ariko hamwe niyongera ryibintu bya alkali, kurwanya alkali, kurwanya ruswa, nibintu byamashanyarazi bizagabanuka.

Ubwoko bwibikoresho bisanzwe bikoreshwa bishimangira nuburyo bukurikira

Ukoresheje imbaraga zingirakamaro zingana, zidafunzefibre fibreIrashobora kugabanwa muburyo butatu: ushyizwe mubudodo bubisi, kugendagenda neza no kugendagenda neza.

Bitewe nuburemere butaringaniye bwimigozi isunitswe, biroroshye kugabanuka, bigatuma habaho guhindagurika kumurongo wibiryo byibikoresho bya pultrusion, bigira ingaruka kumikorere myiza.

Kugenda neza bidasubirwaho bifite ibimenyetso biranga guterana neza, kwinjira byihuse, hamwe nubukorikori buhebuje bwibicuruzwa, bityo ibyinshi mubitambambuga bidasubirwaho bikunda gukoreshwa muri iki gihe.

Kuzunguruka kwinshi ni ingirakamaro mu kunoza imbaraga zo guhinduranya ibicuruzwa, nkibisimba byangiritse hamwe nu mwuka uhumeka. Kuzenguruka kwinshi bifite imbaraga nyinshi zo gukomeza fibre ndende hamwe nubunini bwa fibre ngufi. Nibikoresho bifite ubushyuhe bwo hejuru, ubushyuhe buke bwumuriro, birwanya ruswa, ubushobozi bwinshi hamwe nubushakashatsi bukomeye. Fibre zimwe zegeranijwe muburyo bwa monofilament, bityo irashobora kandi kuzamura ubwiza bwibicuruzwa byimbuto. Kugeza ubu, ibishushanyo byinshi byakoreshejwe cyane mu gihugu no hanze yacyo, nk'imyenda y'intambara no kuboha imyenda yo gushushanya cyangwa inganda. Irashobora gukoreshwa kugirango habeho guterana amagambo, kubika, kurinda cyangwa gufunga ibikoresho.

Ibisabwa kugirango ukore ibirahuri bya fibre idasubirwaho kugirango ubone pultrusion:

(1) Nta kintu kirenze urugero;

(2) Umuvuduko wa fibre ni umwe;

(3) Gufata neza;

(4) Kurwanya kwambara neza;

(5) Hano hari imitwe mike yamenetse, kandi ntabwo byoroshye guhindagurika;

(6) Ubushuhe bwiza no gutera inda byihuse;

(7) Imbaraga nyinshi no gukomera.

2. Mat

Kugirango ukore ibicuruzwa bya FRP byuzuye bifite imbaraga zihagije zo guhinduranya, ibikoresho bishimangira nk'imyenda yacagaguye, materi ikomeza, matel hamwe, hamwe nigitambara kidafunze. Imyenda ikomeza ni imwe mu zikoreshwa cyane mu kirahure fibre transvers yongerera imbaraga muri iki gihe. Kugirango tunoze isura yibicuruzwa,materi yo hejuruni Rimwe na rimwe.

Imyenda ikomeza igizwe nibice byinshi byama fibre yikirahure ikomeza gushyirwaho muruziga, kandi fibre ihujwe nibifatika. Ubuso bwunvikana ni impapuro zoroshye zimeze nkiziko zakozwe muburyo butunguranye kandi bumwe bushyira imirongo yaciwe yuburebure butajegajega kandi ihujwe nigiti. Ibirimo fibre ni 5% kugeza 15%, naho ubunini ni 0.3 kugeza 0.4 mm. Irashobora gutuma ubuso bwibicuruzwa bugenda neza kandi bwiza, kandi bugateza imbere gusaza kwibicuruzwa.

Ibiranga materi ya fibre fibre ni: gukwirakwiza neza, byoroshye kuzuzwa na resin, ibirimo kole nyinshi

Ibisabwa muburyo bwa pultrusion kubirahuri bya fibre fibre:

(1) Ifite imbaraga zo gukanika

.

(3) Ubushuhe bwiza;

(4) Ibintu bike kandi imitwe mike ivunitse.

3. Materi ya polyester fibre

Ubuso bwa polyester fibre yunvikana nubwoko bushya bwo gushimangira ibikoresho bya fibre munganda za pultrusion. Hano hari ibicuruzwa byitwa Nexus muri Reta zunzubumwe zamerika, bikoreshwa cyane mubicuruzwa byimbuto kugirango bisimburweibirahuri bya fibre yububiko. Ifite ingaruka nziza nigiciro gito. Yakoreshejwe neza mumyaka irenga 10.

Ibyiza byo gukoresha materi ya polyester fibre:

(1) Irashobora kunoza ingaruka zo kurwanya ingaruka, kurwanya ruswa hamwe no gusaza kwikirere cyibicuruzwa;

(2) Irashobora kunoza imiterere yibicuruzwa kandi bigatuma ubuso bwibicuruzwa bworoha;

.

(4) Umuvuduko wa pultrusion urashobora kwiyongera;

(5) Irashobora kugabanya kwambara kwububiko no kuzamura ubuzima bwa serivise

4. Ikirahuri cya fibre fibre

Mubicuruzwa bimwe bidasanzwe bya pultruded, kugirango ubashe kuzuza ibisabwa byihariye, imyenda yikirahure ifite ubugari butajegajega hamwe nubunini buri munsi ya 0.2mm, kandi imbaraga zayo zingana nimbaraga zinyuranye nibyiza cyane.

5. Gushyira mu bikorwa imyenda ibiri-yimyenda itatu

Ibikoresho bya transvers yibikoresho bya pultruded yibicuruzwa bikennye birakennye, kandi gukoresha ikoreshwa ryibyerekezo byombi bizamura neza imbaraga nubukomezi bwibicuruzwa byangiritse.

Fibre yintambara hamwe nubudodo bwiyi myenda iboshywe ntabwo ihujwe nundi, ahubwo ihujwe nibindi bikoresho, bityo rero bitandukanye cyane nigitambara gakondo cyibirahure. Fibre muri buri cyerekezo iri mumiterere yegeranye kandi ntabwo ikora Ikintu icyo ari cyo cyose cyunamye, bityo imbaraga nubukomezi bwibicuruzwa byatewe, birarenze cyane ibyibintu bikozwe mubyuma bikomeza.

Kugeza ubu, tekinoroji yuburyo butatu yahindutse urwego rushimishije kandi rukora iterambere ryikoranabuhanga mubikorwa byinganda. Ukurikije ibisabwa byumutwaro, fibre ishimangira ikozwe muburyo butaziguye hamwe nuburyo butatu, kandi imiterere ni nkibya bicuruzwa bigize. Imyenda yuburyo butatu ikoreshwa muburyo bwa pultrusion kugirango itsinde interlaminar shear ya gakondo ikomeza fibre pultrusion. Ifite ibibi byimbaraga zo gukata no gusibanganya byoroshye, kandi imikorere yayo ni nziza cyane.
