Kwemakore mazhinji, kusimbisa simbi kwave kuri chinhu chinonyanya kufarirwa muindasitiri yekuvaka. Zvisinei, huwandu hwakawanda hweruzivo rweinjiniya hunoratidza kuti kana chivakwa chekongiri chakasimbiswa chisina kugadzirwa zvakanaka kana nharaunda iri panzvimbo yacho yakaoma, kugara kwenguva refu uye mashandiro ekusimbisa simbi zvichakanganiswa. Nyanzvi zhinji dzekuChina nedzekunze dzakagumisa kuti kushandisagirazi fiber composite kusimbisaKutsiva simbi muminda chaiyo inzira inoshanda yekugadzirisa dambudziko iri. Kusimbisa simbi mugirazi imhando itsva yezvinhu zvakasanganiswa zvakagadzirwa ne pultrusion uye kugadziriswa kwepamusoro, uchishandisa girazi fiber filaments sekusimbisa, epoxy resin sematrix material, uye uchishandisa ma assistant agents akakodzera (akadai se crosslinking monomers, initiators, accelerators, alteration agents, flame retardants, polymerization inhibitors, fillers, pigments, nezvimwewo).
1. Hunhu hweGirazi Fiber Composite Reinforcement
(1) Simba Rakasimba Rekusimba: Simba rekusimba rekusimbisa girazi fiber rinodarika simba rekusimbisa simbi yakajairika, rinodarika simba rekusimbisa simbi yemhando imwechete ne20%, uye rinodzivirirawo kuneta zvakanaka.
(2) Huremu hushoma: Huremu hwesimbi yegirazi inorema chikamu chimwe chete muzvina chesimbi inosimbaradzwa nehukuru hwakafanana, ine huwandu huri pakati pe1.5 ne1.9 (g/cm3). (3) Kudzivirira ngura kwakasimba: Kunodzivirira ngura kubva kumaacid, alkalis, nemamwe makemikari; Kunodzivirira kukurwa nechloride ions uye low-pH solutions, kunyanya kudzivirira carbon compounds ne chlorine compounds.
(3) Kubatana kwakasimba kwezvinhu: Kuwanda kwekuwedzera kwekupisa kwekongiri yakasimbiswa nefiber yegirazi kwakafanana nekwesimende pane kwesimbi, zvichikonzera kubatana kwakasimba pakati pekongiri yakasimbiswa nefiber yegirazi nekongiri.
(4) Kuchinjika kwakanyanya: Konkriti yakasimbiswa nefaibha yegirazi ine modulus yakasimba uye saizi dzakagadzikana pasi pekumanikidzwa kwekupisa. Inogona kukotama yogadzirwa kuita chero chimiro, ine mashandiro akanaka ekuchengetedza, haifambise mwenje, haisi yemagetsi, haidzoreri moto, uye haigadzirisi static. Nekuchinja kwefomula, haizoburitse sparks kana yasangana nesimbi.
(6) Kupinda kwesimba remagineti: Kongiri yakasimbiswa nefaibha yegirazi chinhu chisina magineti, zvichibvisa kudiwa kwekugadzirisa dhimoni muzvikamu zvekongiri zvisina magineti kana zvemagineti.
(7) Kuvakwa kuri nyore: Konkriti yakasimbiswa nefaibha yegirazi inogona kugadzirwa muzvikamu zvakasiyana-siyana zvakajairwa uye zvisiri zvakajairwa zvine zvikamu zvakasiyana uye urefu hwakasiyana zvichienderana nezvinodiwa nemushandisi. Kusunga panzvimbo kunogona kuitwa uchishandisa tambo dzisina simbi, zvichiita kuti basa rive nyore.
| Zita | Girazi Fiber Composite Yakasimbiswa Bar | Bhawa reSimbi |
| Kuwanda (g/cm)3） | 1.5-1.9 | 7.8-7.9 |
| Simba reKusimba (MPa) | ≥600 | ≥500 |
| Simba reGoho (MPa) | ≥600 | ≥300 |
| Simba Rinodzvinyirira (MPa) | ≥500 | - |
| Modulus yeElasticity (GPa) | ≥40 | 210 |
| Kureba (%) | ≥1.5 | ≥1.8 |
Kusimbiswa kwefiber yegirazi kunoratidza ngura yakasimba zvikuru, kunyanya kana ichitsungirira pH solutions nezvinhu zvinoparadza. Ingave iri munzvimbo dzakanyorova, dzakanyorova kana munzvimbo dzine hunyoro, fiberglass composite reinforcement inoratidza ngura yakanaka mukurima uye inowanzo shanda kwenguva yakareba kupfuura simbi yechinyakare.
2. Kushandiswa kweFiberglass Composite Reinforcement mukurima
(1) Fenzi yekudzivirira kuba yagara ichishandiswa zvakanyanya mukurima. Fenzi yemazuva ano inoshandisa simbi yekusimbisa setsvimbo dzekutsigira, asi kushandiswa kwenguva refu panze kunotungamira mukuora uye kutadza kwesimbi yekusimbisa. Kusasimba kwakasimba kwefiberglass composite resistance kunoita kuti ive yakakodzera kutsiva simbi yekusimbisa setsvimbo dzekutsigira.
(2) Kutsigira miti panguva yekukura kwayo kwakakosha. Matavi ekutsigira akajairika anonyanya kugadzirwa nematanda nesimbi, asi ngura nekukwegura zvinoitika kana ikashandiswa kwenguva refu, zvichiita kuti matavi ekutsigira asashande mumamiriro ekunze akaoma.Kusimbisa kwakabatana kwefiberglassHaingorerutsi chete uye yakasimba asi ine simba rakanaka rekudzivirira ngura, zvichiita kuti ive chigadzirwa chakakodzera kutsiva tsvimbo dzehuni nesimbi.
(3) Mafuremu ekutsigira dzimba dzekurima agara achigadzirwa nematanda nesimbi. Nekuda kwekupisa kwakanyanya uye hunyoro hwenzvimbo, mafuremu ekutsigira akagadzirwa nematanda nesimbi anokwegura uye anoora, zvichikonzera njodzi dzekuchengetedza. Fiberglass composite reinforcement inogona kugadzirwa uye kugadzirwa kuita mafuremu ekutsigira emhando dzakasiyana uye zvakatemwa zvichienderana nezvinodiwa zvekushandisa. Inogona kuiswa zvakananga panzvimbo yacho, yakareruka, uye iri nyore kwazvo kuvaka; chinhu chacho pachacho hachipindi ngura uye hachikweri. Tichifunga nezvekuchengetedzwa uye hupfumi, fiberglass composite reinforcement yakakodzera zvikuru sechimiro chekutsigira greenhouse.
(4) Munguva yekukura kwemichero nemiriwo, mafuremu ekutsigira akakosha kuti akure zviri nani. Mafuremu ekutsigira anowanzo gadzirwa nematanda nesimbi, asi nekuda kwesimba rawo shoma, anowanzo kukwegura uye ngura munzvimbo dzine hunyoro. Kana michero nemiriwo zvakura uye zvasvika pahuremu hwakati, mafuremu ekutsigira anogona kuputsika. Fiberglass composite reinforcement ine hunhu hwekureruka, kusimba kwakanyanya, uye kusaora, zvichiita kuti ive yakakodzera kutsiva huni nesimbi semafuremu ekutsigira michero nemiriwo.
3. MhedzisoFiberglass compositeKusimbisa kunobatanidza hunhu hwakanaka hwe epoxy resin ne fiberglass hwemakanika, hwemuviri, uye hwemakemikari, uye hunoshandiswa zvakanyanya kugadzirisa dambudziko rengura yesimbi munzvimbo dzakakosha dzekushandiswa. Kushanda kwayo zvakanaka pamutengo, kuvakwa kwayo kuri nyore, uye kuramba kwayo ngura kwakanaka kwakaita kuti itsive simbi zvishoma nezvishoma uye itore nzvimbo mumunda wekurima, zvichiita basa rakakosha mukusimudzira hupfumi hwenyika.
