Chifukwa cha chizolowezi chofuna masamba akuluakulu a mphepo komanso a m'mphepete mwa nyanja, kukhazikika, mphamvu, ndi kugwirizana kwa njira zopangira zinthu zophatikizika kumatsimikiza mwachindunji nthawi ya masamba ndi momwe magetsi amagwirira ntchito. Monga gawo lofunikira lothandizira zipolopolo za masamba, maukonde, m'mphepete motsogozedwa, m'mphepete motsatizana, ndi zigawo zina,mphasa yodulidwa ya ulusi (CSM)chakhala chida chodziwika bwino cha VARTM vacuum infusion ndi hand lay-up/compression molding chifukwa cha kufanana kwake kwabwino, kulowetsedwa mwachangu, kupangika bwino, komanso kulimba kwamphamvu pakati pa laminar. Kusankha molakwika kwa grade kapena kulemera kungayambitse mavuto ang'onoang'ono monga zolakwika pamwamba kapena resin voids panthawi ya infusion, kapena kusokoneza kwambiri mphamvu ya kapangidwe kake ndi magwiridwe antchito otopa. Pepalali limafotokoza mwatsatanetsatane ma grade okhazikika, specifications zapakati, logic yosankha, ndi kuyanjana kwa ntchito pa mphasa zodulidwa zomwe zimagwiritsidwa ntchito mu masamba a wind turbine.

Mat odulidwa a StrandZa Masamba a Wind Turbine: Malo Oyambira ndi Zofunikira Zapakati

Matiketi odulidwa a ulusi wa wind turbine amagwiritsa ntchito ulusi wa E-glass wopanda alkali wokhala ndi mainchesi a 9–13μm ndi kutalika kodulidwa kwa 12–25mm, omwe amakwaniritsa miyezo ya GB/T 17470 ndipo amagwirizana ndi machitidwe a epoxy/vinyl ester resin.

Mipata Yofunikira Yogwirira Ntchito

- Kupatuka kwa kulemera kwa dera: ± 5%

- Chinyezi: ≤0.2%

- Mphamvu yokoka: ≥30–180 N/5 cm (imawonjezeka ndi kulemera kwa basis)

- Kusalowa m'mimba: Kukhuta mwachangu, kuphulika pang'ono, koyenera kulowetsedwa mu vacuum

- Kukana kupopera kwa nyengo/mchere: Chitetezo chowonjezereka cha dzimbiri chikufunika pa mitundu ya m'mphepete mwa nyanja

- Kukhazikika: Palibe kutayika kwa ufa, palibe kuchotsedwa kwa ufa, palibe fuzz; yoyenera kuyikidwa yokha

Mpando wodulidwa wa chingwe makamaka umathandiza kuti ukhale wolimba osati wonyamula katundu wofunikira, kufanana kwa pamwamba, kusintha kwa zigawo, komanso kukana kusintha kwa masamba. Umapanga gawo lonse la kapangidwe kake ukaphatikizidwa ndi nsalu zolunjika mbali imodzi, nsalu zozungulira mbali zambiri, mphanda zopitilira, ndi mphanda zozungulira.

Tsamba la Turbine la MphepoMat odulidwa a StrandMa Model ndi Mafotokozedwe

Mitundu yodziwika bwino ya mafakitale imaphatikizapo mitundu ya EMC (emulsion)/CMC (ufa) yokhala ndi m'lifupi wofanana wa 1250/1040/2500 mm. Pansipa pali mitundu yomwe imagwiritsidwa ntchito kwambiri popanga masamba ambiri:

1) Ma Model Okhazikika ndi Ma Grammages Ogwirizana

- EMC225/CMC225: 225g/m², wosanjikiza woonda wosinthika wokhala ndi mawonekedwe abwino

- EMC300/CMC300: 300 g/m², chinthu chofunikira kwambiri pa ntchito zonse ziwiri za chipolopolo ndi za pa intaneti

- EMC450/CMC450: 450 g/m², mphamvu yapakati yolimbikitsira madera onyamula katundu

- EMC600/CMC600: 600 g/m², cholimbitsa chokhuthala kuti mizu/m'mphepete mwake mukhuthale

- EMC900: 900 g/m², mphamvu yolimba yolimbitsa masamba akuluakulu m'deralo

2) Kusankha Mtundu Womatira

- EMC yochokera ku Emulsion: Mphamvu yayikulu, kufanana kwabwino, kuyanjana kwabwino kwambiri kwa utomoni; yabwino kwambiri poika vacuum infusion

- CMC yochokera ku ufa: Imalowa mwachangu, yotsika mtengo, yoyenera kuyikidwa m'manja/njira zothandizira

- Mphamvu ya mphepo ya m'mphepete mwa nyanja, masamba amphamvu kwambiri: Ikani patsogolo mndandanda wa EMC emulsion

3) Kukula kwa intaneti ndi kufananiza njira

- 1250mm/1040mm: Masamba ang'onoang'ono mpaka apakati, okonzedwa ndi manja

- 2500mm ndi kupitirira apo: Masamba akuluakulu, makina okhazikika okha, kupendekera kochepa

Kusankha ndi Gawo: Kodi Mungagwirizanitse Bwanji Malo Osiyana a Tsamba?

1) Chigoba Chakunja/Undercoat Yokhala ndi Magalasi

- Yolangizidwa: EMC225 / EMC300

- Mfundo Zofunika: Kusalala kwa pamwamba, mabowo ochepa, mawonekedwe abwino komanso kukana nyengo

2) Gawo Lalikulu la Chipolopolo (Kusintha/Gawo Loyenera)

- Yolangizidwa: EMC300

- Mfundo zazikulu: Mphamvu yoyenera komanso kuyika bwino, bwino kwambiri ndi nsalu zokhala ndi ma axial ambiri

3) Ukonde, chivundikiro cha mbali yolimbitsa

- Yolangizidwa: EMC450

- Mfundo zazikulu: Kulimba kwambiri, kukana kudulidwa, kukhazikika bwino kwa kapangidwe kake

4) Mphepete mwa kutsogolo, m'mphepete mwa kumbuyo, malo okhuthala mizu

- Yolangizidwa: EMC600 / EMC900

- Mfundo zazikulu: Kuumba mwachangu, kuchepetsa kuchuluka kwa ma ply, kukana bwino kugwedezeka

5) Masamba a turbine ya mphepo ya m'mphepete mwa nyanja (kupopera mchere/kunyowa kwambiri)

- Yolangizidwa: EMC300/450 yopepuka pang'ono + yosagwira madzi

- Mfundo zazikulu: Kulimbitsa kukana ukalamba, kuchepetsa chiopsezo cha delamination

Mpando wodulidwa ndi chingwe poyerekeza ndi zinaulusimphasa zagalasi: N’chifukwa chiyani imakondedwa ndi masamba?

1) Mpando Wodulidwa ndi Ulusi Wosalekeza

- Chodulidwa Chingwe: Chopanda kutentha, chophimba bwino cha nkhungu, choyenera malo opindika komanso kulowetsedwa

- Mat Yopitilira: Mphamvu yayitali kwambiri, kufanana kochepa pang'ono

- Kumanga Tsamba: Nsalu yodulidwa ya thupi lalikulu, nsalu yopitilira/yolunjika imodzi ya madera akuluakulu onyamula katundu

2) Mpando Wodulidwa ndi Nsalu vs. Mpando Wobayidwa ndi Singano

- Mati obowola ndi singano: Mphamvu zambiri, mtengo wake ndi wokwera

- Mati odulidwa: Osavuta kugwiritsa ntchito, otsika mtengo, komanso opanda zolakwika zambiri

- Kusankha: Nsalu yodulidwa ndi yokhazikika komanso yotsika mtengo m'malo osanyamula katundu

3) Mpando Wodulidwa ndi Wachitsulo Chodulidwa ndi Wapamwamba

- Mpando wa pamwamba: 30–120 g/m², wongogwiritsidwa ntchito potseka kukongola kokha

- Matcheti Odulidwa: Ntchito ziwiri zolimbitsa kapangidwe kake + kufanana kwa pamwamba

- Kuphatikiza: Mpando wapamwamba + mphando wodulidwa wa chingwe + nsalu ya axial yambiri imapanga mzere wokhazikika wa tsamba

Njira Yosankhira Masitepe Asanu

1. Ganizirani Njira: Kuthira mu vacuum → Sankhani EMC emulsion; Kuyika manja → Sankhani ufa wa CMC

2. Ganizirani Malo: Malo okhota/kunja → 225/300g; Kulimbitsa → 450/600g; Yolemera → 900g

3. Zofunika Kuganizira za Resin: Machitidwe a Epoxy → Tsimikizirani kugwirizana kwa mimba; Kugwiritsa ntchito m'madzi → Mitundu yolimbana ndi Hydrolysis

4. Kukula kwa Web: Gwiritsani ntchito maukonde otakata pa masamba akuluakulu kuti muchepetse kupingasa ndi zolakwika

5. Miyezo Yabwino: Kupatuka kwa ma gramme ≤±5%, Kuchuluka kwa chinyezi ≤0.2%, Palibe kutayika kwa ufa kapena fuzz

Mavuto Ofala ndi Njira Zopewera

- Kungoyang'ana pa mtengo wokha popanda kuganizira za binder: Mapeti a ufa omwe amagwiritsidwa ntchito mu infusion angayambitse kulowa kosalingana

- Kukweza kulemera mwachisawawa: Kukhuthala kwambiri kungayambitse kulowetsedwa kosakwanira ndi zolakwika pakati pa zigawo

- Kunyalanyaza m'lifupi ndi kupingasa: Kupingasa kwakukulu kumawonjezera chiopsezo cha thovu ndi malo ouma

- Kugwiritsa ntchito zinthu zomwezo pa ntchito za m'madzi ndi zapamtunda: Kugwiritsa ntchito m'madzi kumafuna magiredi apadera olimbana ndi hydrolysis/osapsa kwambiri
