Kujekesa tekinoroji yekugadzira mica chubhu

Mica chubhu inochinjika-chikamu chakakomberedza bar chakagadzirwa nealkali-isina girazi fiber jira rakanyikwa mu epoxy resin, yakabikwa muforoma, uye inopisa yakatsindirwa. Iyo girazi jira tsvimbo ine yakakwira michina zvivakwa. Icho pamusoro peiyo mica chubhu chinofanira kuve chakatsetseka uye chisina mabhuru, mafuta uye tsvina. Ruvara rusina kukwana, kukwiza zvishoma, nezvimwe zviri mukati meyakagamuchirwa nzvimbo. Epoxy resin mapaipi anoshandiswa kuputira zvikamu zvemagetsi magetsi, nharaunda dzinonyorova uye oiri yeshanduko.

Sezvo isu tese tichiziva, mashandiro epoxy resin pombi yakanaka kwazvo, saka ndeipi nzira yekugadzira ino yakanaka kwazvo epoxy resin pombi?

1. Pisai epoxy resin mubhavhu remvura kusvika pa 85-90 ° C, wedzera mushonga unorapa zvinoenderana neresini / inorapa mumiririri (reshiyo yenhamba) = 100/45, fambisa kuti inyunguduke, uye chengetera mutangi yeglue pa80-85 ° C.

2. Girazi faibha rinokuvadzwa pane simbi yakakomberedzwa yesimbi, iyo longitudinal ichitenderera kona iri 45 °, uye upamhi hweshinda yefaera iri 2.5mm. Iyo fiber dura inoumbwa ne3.5mmmm kureba kwekutenderera + 2 masendimita ekutenderera akakomberedza + 3.5mm gobvu refu yekureba ichitenderera + 2 zvidimbu zvekutenderera kwekutenderera.

3. Tsvaira resin solution kuitira kuti zvinongedzo zveglue zvechigadziko chakakomberedza iyo fiber zvigoverengerwa kuve 26%.

4. Isa kapurasitiki kapfupi-kanodzikira pombi yepurasitiki padenga rekunze, kurifuridza nemhepo inopisa uye kuriputira rakasimba, wobva waputira iyo yekunze dhayamita ine 0.2 mm gobvu uye 20 mm yakafara girazi rejira jira woitumira kuchoto chinoporesa yekurapa.

5. Kurapa kudzora: tanga kukwidza tembiricha yemukamuri kubva mukamuri tembiricha kusvika 95 ° C pachiyero che3 ° C / 10min, wozoipisa kusvika 160 ° C panguva imwechete yekukwira tembiricha inokwira 4h, wozoitonhodza kubva hovhoni kutembiricha yemukati.

6. Iyo mica chubhu inodonhedzwa, iyo girazi jira tepi pamusoro pevhu inobviswa, uye yozogadziriswa sezvinodiwa.
