Kuti uve nechokwadi chemhando yehombe-caliber epoxy girazi fiber pombi, chii chinodiwa kune zvigadzirwa zvekugadzira

Huru-diameter epoxy girazi faibha chubhu inogadzirwa nemagetsi alkali-isina girazi faibha jira rakaiswa epoxy resin, uye rinogadziriswa nekubheka uye kupisa nekutsikirira mukugadzira mold. The cross-section is a round rod. Iyo girazi jira tsvimbo ine yakakwirira mechanical properties. .

Dielectric zvivakwa uye yakanaka machinability. Giredhi rekudzivirira kupisa rinogona kukamurwa kuita B giredhi (130 madhigirii) F giredhi (155 madhigirii) H giredhi (180 madhigirii) uye C giredhi (pamusoro 180 madhigirii). Yakakodzera kuvharidzira zvikamu zvezvimiro mumidziyo yemagetsi, uye inogona kushandiswa munzvimbo ine nyoro uye transformer mafuta.

Nzvimbo yacho inofanira kunge yakadzikama uye yakatsetseka, isina mabhuru, mafuta uye tsvina. Kusaenzana kwemavara, kukwenya, kureba kushoma kusaenzana izvo zvisingatadzise kushandiswa zvinobvumidzwa. Laminated girazi jira rods ane dhayamita anopfuura 25mm anobvumirwa kuva makatsemuka pamagumo kana chikamu asingatadzi kushandiswa.

Huru-caliber epoxy girazi fiber chubhu inoumbwa ne epoxy resin, kurapa mumiririri, accelerator uye zvinowedzera. Izvo zvikamu zve epoxy resin glue hazvifanirwe kufunga kwete chete izvo zvinodiwa zvehunyanzvi zvechigadzirwa chakarapwa (nekuti kushomeka kwekupisa, makemikari kuramba, uye electromechanical zvimiro zvechigadzirwa chinopetana zvinoenderana nekuumbwa kweepoxy resin glue), asiwo zvinodiwa the winding molding process , Zvikasadaro haigone kukuvadzwa kuita chimiro. Nechikonzero ichi, izvo zvinodikanwa zveepoxy resin glue ndezvinotevera.

①Kunyungudika kweglue resin kunofanirwa kuve kwakanaka kuona kuti mafiber akazara, zviri mukati meglue zvakafanana, uye mabhuru ari mumucheka weshinda anogona kuburitswa. Nokudaro, viscosity yayo inofanira kudzorwa mukati me 0.35 ~ 1Pa · s. Kana iyo viscosity idiki, kupindira kwakanaka, asi zviri nyore kurasikirwa neglue content uye kukanganisa electromechanical performance yechigadzirwa. Zvisinei, kana viscosity yakakura zvikuru, zvakaoma kupinda mukati mefiber gap, zvichiita kuti nhamba huru yemabhubhu muchigadzirwa, iyo inokanganisawo kunaka kwechigadzirwa. Uyezve, iyo yakakwira viscosity inokonzera kushushikana kwakanyanya, izvo zvinounza kusagadzikana kune iyo mhepo nzira.

②Nguva yekushandisa inofanira kuva yakareba. Kuti uchengetedze mhepo yakatsetseka, nguva yegel yeglue inofanira kuva yakakura kudarika 4h

③Kurebera kweyakarapwa resin glue fluid inofanana nekusimbisa zvinhu, izvo zvinogona kudzivirira mukati kushushikana panguva yekurapa.

④Iyo resin glue fluid haina kunyungudika, kuitira kuti pave neashoma anoshanduka uye kudzivirira kunyungudika kwe solvent panguva yekurapa kunokanganisa kuzara kwechigadzirwa. Izvi zvakatonyanya kukosha kune mhepo yakaumbwa yekuvharisa zvikamu zvinoshandiswa muzvigadzirwa zvemagetsi.

Iyo chubhu yepakati inoshandiswa kune hombe-diameter epoxy girazi faibha chubhu yakakungurutswa laminated chubhu chinhu chakakosha pakugadzira laminated chubhu. Kururama kwaro kunokanganisa zvakananga kurongeka kwemukati wemukati wechubhu yelaminated, uye kushata kwayo kwepamusoro kunobata zvakananga kushata kwemukati wemadziro echubhu yelaminated. Naizvozvo, zvinodikanwa kuchengetedza pamusoro peiyo tube core kubva kumapumbu, ngura uye deformation panguva yekugadzira, kutakura uye kuchengetedza.
