Sekuyiminyaka eminingi, ukuqinisa insimbi kube yinto yokwakha eyisisekelo ethandwa kakhulu embonini yokwakha. Kodwa-ke, inani elikhulu lemininingwane yobunjiniyela bangempela libonisa ukuthi uma isakhiwo sekhonkrithi esiqinisiwe singaklanywanga kahle noma indawo yasendaweni inzima, ukuqina nokusebenza kokuqinisa insimbi kuzothinteka. Izazi eziningi zaseShayina nezakwamanye amazwe ziphethe ngokuthi ukusebenzisaukuqinisa ingilazi yefayibha ehlanganisiweukufaka esikhundleni sokuqinisa insimbi emikhakheni ethile kuyindlela ephumelelayo yokuxazulula le nkinga. Ukuqinisa i-fiber ehlanganisiwe yengilazi uhlobo olusha lwezinto ezihlanganisiwe ezakhiwe yi-pultrusion kanye nokwelashwa okukhethekile kwendawo, kusetshenziswa imicu ye-fiber yengilazi njengokuqinisa, i-epoxy resin njengezinto ze-matrix, kanye nokufaka ama-ejenti asizayo afanele (njenge-crosslinking monomers, ama-initiators, ama-accelerator, ama-alteration agent, ama-flame retardants, ama-polymerization inhibitors, ama-fillers, ama-pigment, njll.).
1. Izici Zokuqinisa I-Glass Fiber Composite
(1) Amandla Okuqinela Aphezulu: Amandla okuqinela okuqinisa ifayibha yengilazi angcono kunalawo okuqinisa insimbi evamile, adlula lawo okuqinisa insimbi okufana nokwencazelo efanayo ngo-20%, futhi inokumelana okuhle nokukhathala.
(2) Isisindo Esilula: Isisindo sokuqinisa i-fiber yengilazi siyingxenye eyodwa kwezine kuphela yesisindo sokuqinisa insimbi esinomthamo ofanayo, ngobuningi obuphakathi kuka-1.5 no-1.9 (g/cm3). (3) Ukumelana nokugqwala okunamandla: Kumelana nokugqwala okuvela kuma-acid, ama-alkali, namanye amakhemikhali; kumelana nokuguguleka kwama-ion e-chloride kanye nezixazululo ze-pH ephansi, ikakhulukazi ukumelana okunamandla kwama-compound e-carbon kanye nama-compound e-chlorine.
(3) Ukubopha okuqinile kwezinto: I-coefficient yokwanda kokushisa kwekhonkrithi eqiniswe ngefayibha yengilazi iseduze nokwesimende kuneyensimbi, okuholela ekubopheni okuqinile phakathi kwekhonkrithi eqiniswe ngefayibha yengilazi kanye nekhonkrithi.
(4) Ukuguquguquka okuphezulu komklamo: Ikhonkrithi eqiniswe ngefayibha yengilazi ine-modulus ezinzile nezingaguquguquki ngaphansi kokucindezeleka kokushisa. Ingagotshwa futhi yenziwe nganoma yisiphi isimo, isebenza kahle ngokuphepha, ayiqhubi, ayisebenzi ngogesi, ayivimbi ilangabi, futhi ayimelani nokuma. Ngoshintsho kufomula, ngeke ikhiqize izinhlansi lapho ishayisana nezinsimbi.
(6) Ukungena kwamandla kagesi okunamandla: Ikhonkrithi eqiniswe ngefayibha yengilazi iyinto engeyona i-magnetic, okususa isidingo sokwelashwa kwe-demagnetization ezingxenyeni zekhonkrithi ezingeyona i-magnetic noma i-electromagnetic.
(7) Ukwakhiwa okulula: Ikhonkrithi eqiniswe ngefayibha yengilazi ingakhiqizwa ngezingxenye ezahlukene ezijwayelekile nezingezona ezejwayelekile ezinezingxenye ezahlukene nobude obuhlukene ngokwezidingo zomsebenzisi. Ukubopha endaweni kungenziwa kusetshenziswa izintambo zokucindezela ezingezona ezensimbi, okwenza umsebenzi ube lula.
| Igama | Ibha Eqinisiwe Ye-Glass Fiber Composite | Ibha Yensimbi |
| Ubuningi (g/cm)3） | 1.5-1.9 | 7.8-7.9 |
| Amandla Okuqina (MPa) | ≥600 | ≥500 |
| Amandla Okukhiqiza (MPa) | ≥600 | ≥300 |
| Amandla Okucindezela (MPa) | ≥500 | - |
| I-Modulus ye-Elasticity (GPa) | ≥40 | 210 |
| Ukwandiswa (%) | ≥1.5 | ≥1.8 |
Ukuqinisa i-fiber ehlanganisiwe yengilazi kubonisa ukumelana okukhulu kakhulu nokugqwala, ikakhulukazi ngokubekezelela okuphezulu izixazululo ze-pH nezinto ezigqwalisayo. Kungakhathaliseki ukuthi kusezindaweni ezivezwe, ezimanzi emvuleni noma ezindaweni ezinomswakama, ukuqinisa i-fiberglass ehlanganisiwe kubonisa ukumelana okuhle nokugqwala kwezolimo futhi ngokuvamile kunesikhathi eside senkonzo kunokuqinisa insimbi yendabuko.
2. Ukusetshenziswa Kokuqinisa I-Fiberglass Composite Kwezolimo
(1) Ucingo lokulwa nokwebiwa selusetshenziswa kabanzi kwezolimo isikhathi eside. Ucingo oluvamile lusebenzisa ukuqinisa insimbi njengezinduku zokusekela, kodwa ukusetshenziswa isikhathi eside ngaphandle kuholela ekugqwaleni nasekuhlulekeni kokuqinisa insimbi. Ukumelana okunamandla kokugqwala kokuqinisa okuhlanganisiwe kwe-fiberglass kuyenza ifaneleke kakhulu njengokufaka esikhundleni sokuqinisa insimbi njengezinduku zokusekela.
(2) Ukusekela izihlahla ngesikhathi zikhula kubalulekile. Izinduku zokusekela ezivamile zenziwe ngokhuni nensimbi, kodwa ukugqwala nokuguga kwenzeka ngesikhathi sokusetshenziswa isikhathi eside, okwenza izinduku zokusekela zingasebenzi kahle ezimweni zezulu ezinzima.Ukuqinisa okuhlanganisiwe kwe-fiberglassAkuyona nje kuphela elula futhi enamandla aphezulu kodwa futhi inokumelana okuhle nokugqwala, okwenza kube umkhiqizo ofaneleka kakhulu ukufaka esikhundleni sezinduku zokusekela zokhuni nensimbi.
(3) Amafreyimu okusekela ezindawo zokugcina izitshalo zezolimo avame ukwenziwa ngokhuni nensimbi. Ngenxa yokushisa okuphezulu kanye nomswakama wendawo, amafreyimu okusekela enziwe ngokhuni nensimbi azoguga futhi agqwale, okubeka izingozi zokuphepha. Ukuqinisa okuhlanganisiwe kwe-fiberglass kungaklanywa futhi kwenziwe kube amafreyimu okusekela amamodeli ahlukene kanye nemininingwane ngokuya ngezidingo zokusebenzisa. Kungafakwa ngqo endaweni, kulula, futhi kulula kakhulu ukwakha; izinto ngokwazo nazo azikwazi ukugqwala futhi azikwazi ukuguga. Uma kucatshangelwa ukuphepha kanye nokonga, ukuqinisa okuhlanganisiwe kwe-fiberglass kufanelekile kakhulu njengesakhiwo sokusekela i-greenhouse.
(4) Ngesikhathi sokukhula kwezithelo nemifino, ozimele bokusekela babalulekile ekukhuleni kwabo okungcono. Ozimele bokusekela abavamile bakhiwe kakhulu ngokhuni nensimbi, kodwa ngenxa yamandla abo aphansi, bathambekele ekugugeni nasekugqwaleni ezindaweni ezinomswakama. Uma izithelo nemifino sezivuthiwe futhi zifinyelela isisindo esithile, ozimele bokusekela bangase bawe. Ukuqinisa okuhlanganisiwe kwe-fiberglass kunezici zokuba lula, amandla aphezulu, kanye nokumelana nokugqwala, okwenza kube kuhle kakhulu ukufaka esikhundleni sokhuni nensimbi njengozimele bokusekela izithelo nemifino.
3. IsiphethoInhlanganisela ye-fiberglassUkuqinisa kuhlanganisa izakhiwo ezinhle kakhulu zemishini, zomzimba, kanye nezamakhemikhali ze-epoxy resin kanye ne-fiberglass, futhi kusetshenziswa kabanzi ukuxazulula inkinga yokugqwala kwensimbi ezindaweni ezikhethekile zokusetshenziswa. Ukusebenza kwayo kahle kwezindleko, ukwakhiwa kwayo okulula, kanye nokumelana nokugqwala okuhle kakhulu kuye kwaholela ekutheni ithathe indawo yensimbi kancane kancane futhi ithathe indawo emkhakheni wezolimo, idlala indima ebalulekile ekuthuthukisweni komnotho wezwe.
