Nekuda kwekufambira mberi kwemashizha emhepo makuru uye ekunze kwegungwa, kugadzikana, simba, uye kuenderana kwemaitiro emasisitimu ezvinhu zvakagadzirwa zvinosarudza zvakananga hupenyu hwemashizha uye kushanda zvakanaka kwekugadzira magetsi. Sechinhu chakakosha chekusimbisa masherufu emashizha, mawebhu, mipendero inotungamira, mipendero inotevedzana, nezvimwe zvikamu,jira rakachekwa (CSM)rave chinhu chakajairika cheVARTM vacuum infusion uye hand lay-up/compression molding nekuda kwekufanana kwayo kwakanaka, kukurumidza kuisirwa, kugona kuumbwa kwepamusoro, uye kubatana kwakasimba pakati pelaminar. Kusasarudzwa kwegiredhi kana huremu zvisirizvo kunogona kukonzera matambudziko madiki senge kusakwana kwepamusoro kana resin voids panguva yekuisirwa, kana kukanganisa zvakanyanya simba rechimiro uye kushanda kwekuneta. Pepa iri rinotsanangura zvakarongeka mamakisi akajairwa, zvirevo zvepakati, pfungwa dzekusarudza, uye kuenderana kwekushandiswa kwemachira etambo akachekwa anoshandiswa mumabhura emhepo.

Mat Yakachekwa-chekwa yeStrandyeWind Turbine Blades: Nzvimbo yeFoundation uye Zvinodiwa zveCore

Matinji esimbi akachekwa nemhepo anoshandisa machira eE-glass asina alkali ane dhayamita ye9–13μm uye kureba kwakachekwa kwe12–25mm, achisangana nezvinodiwa zveGB/T 17470 uye anoenderana ne epoxy/vinyl ester resin systems.

Zvipingamupinyi Zvikuru Zvekushanda

- Kutsauka kwehuremu hwenzvimbo: ± 5%

- Hunyoro: ≤0.2%

- Simba rekudhonza: ≥30–180 N/5 cm (rinowedzera nehukuru hwechigadziko)

- Kusapinda: Kukurumidza kuzara, kufashaira kushoma, kwakakodzera kuisirwa mu vacuum

- Kudzivirira kupfapfaidzwa kwemvura yekunze/munyu: Dziviriro yakawedzerwa yengura inodiwa kune mamodheru ekunze

- Kugadzikana: Hapana kudonhedza upfu, hapana kucheka, hapana fuzz; yakakodzera kurongedzwa otomatiki

Mati akachekwa anonyanya kubatsira kusimbisa zvinhu zvisingatakure mutoro, kufanana kwenzvimbo, kushanduka kwenzvimbo, uye kuramba kuchinjika kwemaburi. Anoumba chivakwa chakazara kana akabatanidzwa nemachira akaenzana, machira ane axial akawanda, mati anoenderera mberi, uye mati epamusoro.

Mhepo yeTurbine BladeMat Yakachekwa-chekwa yeStrandMamodheru uye Magadzirirwo

Mhando dzemhando dzeindasitiri dzinosanganisira mhando dzeEMC (emulsion)/CMC (hupfu) dzine upamhi hwakajairika hwe1250/1040/2500 mm. Heano mamodheru anoshandiswa zvakanyanya pakugadzira blade mass:

2) Sarudzo yeRudzi rweNamatidza

- EMC yakavakirwa paEmulsion: Simba guru, kufanana kwakanaka, kuenderana neresin yepamusoro; inofarirwa kushandiswa pakushandisa vacuum infusion

- CMC yakagadzirwa nehupfu: Inopinda nekukurumidza, isingadhuri, yakakodzera kugadzirira nemaoko/maitiro ekubatsira

- Simba remhepo rekunze kwegungwa, mashizha ane simba guru: Isa pamberi EMC emulsion nhevedzano

3) Kufara kweWebhu uye Kufananidza Maitiro

- 1250mm/1040mm: Mapadza madiki kusvika pakati, akarongwa nemaoko

- 2500mm zvichikwira: Mapazi makuru, otomatiki layup, kupindirana kwakaderera

Kusarudzwa neChikamu: Ungaenzanisa Sei Nzvimbo Dzakasiyana dzeMabanga?

1) Goko rekunze/Glassing Undercoat

- Zvinokurudzirwa: EMC225 / EMC300

- Pfungwa huru: Kutsvedzerera kwepamusoro, maburi mashoma, chitarisiko chakawedzerwa uye kuramba mamiriro ekunze

2) Chigadziko Chikuru cheShell (Chikamu Chekuchinja/Chikamu Chekuyera)

- Zvinokurudzirwa: EMC300

- Pfungwa huru: Simba rakaringana uye kuisirwa kwemuviri, zvakanaka kwazvo nemachira ane axial akawanda

3) Webhu, chivharo chedanda chinosimbisa divi

- Zvinokurudzirwa: EMC450

- Pfungwa huru: Kuomarara kwakanyanya, kuramba kuchekwa kweganda, kugadzikana kwechimiro kwakawedzerwa

4) Mupendero wepamberi, mupendero wepashure, nzvimbo dzekukora kwemidzi

- Zvinokurudzirwa: EMC600 / EMC900

- Pfungwa huru: Kugadzira nekukasika, kuderedzwa kwehuwandu hwema ply, kuwedzera kwekudzivirira kukanganiswa

5) Mapazi emhepo anofefetera kunze kwenyika (munyu unopfapfaidza/hunyoro hwakawanda)

- Zvinokurudzirwa: EMC300/450 isina kusimba zvakanyanya + mushonga unopinzwa usingapindi mvura

- Pfungwa huru: Kuwedzera kuramba kukwegura, kuderedza njodzi yekubvisa ganda kubva muganda

Meti yakachekwa-chekwa vs. mamwefaibhamagirazi emeti: Sei ichinyanya kufarirwa pamashizha?

1) Mat Yetambo Yakachekwa vs Mat Yetambo Inoramba Ichishandiswa

- Mat Yakachekwa: Isotropic, inofukidza chakuvhuvhu zvakanaka, yakakodzera nzvimbo dzakakombama uye inoiswa musanganiswa wemvura.

- Mat inoenderera mberi: Simba rakakwirira rehurefu, kufanana kwakaderera zvishoma

- Kugadzira Blade: Tambo yakachekwa yemuviri mukuru, jira rinoenderera mberi/rinotenderera rimwe chete renzvimbo huru dzinotakura mutoro

2) Mat Yetambo Yakachekwa vs Mat Yakaboorwa Netsono

- Mateti ekuboorwa netsono: Simba rakawanda, mutengo wakakwira

- Matavi akachekwa: Anoshanda zvakanaka pakugadzirisa, anochengetedza mari, uye ane zvikanganiso zvishoma

- Sarudzo: Tambo yakachekwa yakasimba uye inodhura zvishoma kune nzvimbo dzisingatakure mutoro

3) Mat Yetambo Yakachekwa vs. Mat Yepamusoro

- Meti yepamusoro: 30–120 g/m², chete yekuvhara runako

- Mat Yetambo Yakachekwa: Mashandiro maviri ekusimbisa chimiro + kufanana kwenzvimbo

- Musanganiswa: Meti yepamusoro + meti yetambo yakachekwa + jira rine axial yakawanda rinoita kuti blade rive rakajairwa

Nzira yekusarudza matanho mashanu

1. Funga nezveMaitiro: Kuisirwa muchina wekuchenesa → Sarudza EMC emulsion; Kuisa maoko → Sarudza CMC powder

2. Funga nezvenzvimbo: Nzvimbo dzakakombama/dzekunze → 225/300g; Kusimbisa → 450/600g; Inorema → 900g

3. Zvaunofanira Kufunga Nezve Resin: Masisitimu eEpoxy → Simbisa kuti impregnant inoenderana here; Mashandisirwo emvura → Mhando dzinodzivirira Hydrolysis

4. Upamhi hwewebhu: Shandisa mawebhu akafara pamashizha makuru kuderedza kupindirana uye zvikanganiso

5. Maitiro Emhando Yepamusoro: Kutsauka kweGrammage ≤±5%, Hunyoro ≤0.2%, Hapana kudonha kwehupfu kana fuzz

Dambudziko Rakajairika uye Maitiro Ekudzivirira

- Kungotarisa pamutengo chete pasina kufunga nezve binder: Matinji eupfu anoshandiswa mu infusion anogona kukonzera kusapindirana kwemvura

- Kuwedzera huremu zvisina tsarukano: Kukobvu kwakanyanya kunogona kukonzera kusakwana kwemushonga uye zvikanganiso zvepakati pezvikamu

- Kuregeredza upamhi nekukwirirana: Kupindirana kwakawandisa kunowedzera njodzi yemafuro nenzvimbo dzakaoma

- Kushandisa chinhu chimwe chete pakushandiswa kwemvura nepasi: Kushandiswa kwemvura kunoda magiredhi akasarudzika anodzivirira hydrolysis/asina fuzz yakawanda
