Kugadzira maitiro emhando yepamusoro epoxy girazi fiber board

A. Kugadzirira kwepamusoro uye kurapwa kwe epoxy girazi jira laminate zvigadzirwa

1. Mushure mokunge mhangura yemhangura yakarongedzwa uye yakasungirirwa kuti iite dunhu, edza kuderedza kurapwa uye kubata paPTFE pamusoro. Mushandi anofanirwa kupfeka magirovhosi akachena uye oisa firimu remukati pabhodhi rega rega kuti ripfuure kune rinotevera maitiro.

2. The etched PTFE pamusoro ane zvakakwana roughness kuti bonding. Ikoko mapepa akaiswa kana kuti laminates asina kuvharwa achabatanidzwa, zvinokurudzirwa kubata PTFE pamusoro kuti upe hukama hwakakwana. Iyo makemikari emakemikari anoshandiswa mune pth kugadzirira maitiro anogonawo kushandiswa pakurapa kwepamusoro. Kurudzira plasma etching kana sodium-ine makemikari reagents, akadai FluroEtch®byActon, TetraEtch®byGore, uye Bond-Prep®byAPC. Iyo chaiyo yekugadzirisa tekinoroji inopiwa nemutengesi.

3. Mushonga wemhangura wepamusoro unofanirwa kuve nechokwadi chesimba rakanakisisa rekubatanidza. Iyo yebrown copper monoxide yedunhu kurapwa inosimbisa chimiro chepamusoro kufambisa kemikari kubatana neTacBond adhesive. Nzira yekutanga inoda muchenesi kubvisa zvakasara uye mafuta ekurapa. Zvadaro, etching yakanaka yemhangura inoitwa kuti iite yunifomu yakaoma nzvimbo. Iyo brown oxide tsono makristasi anodzikamisa iyo yekubatanidza dhizaini panguva yekugadzira lamination. Sezvakaita chero makemikari maitiro, kuchenesa kwakakwana mushure meimwe nhanho yegadziriro inodiwa. Munyu wakasara uchadzivisa kunamatira. Iyo yekupedzisira yekugezesa inofanirwa kuongororwa uye iyo pH kukosha inofanira kuchengetwa iri pasi pe8.5. Dry layer by layer uye ona kuti nzvimbo yacho haina kusvibiswa nemafuta pamaoko.

B. Kufukidzira uye lamination

Inokurudzirwa kubatana (kudzvanya kana kudzvanya) tembiricha: 425°F (220°C)

Kubika plies pa 1.250oF (100 ° C) kubvisa unyoro. Iwo akaturikidzana anochengetwa munzvimbo yakadzorwa zvakasimba uye anoshandiswa mukati memaawa makumi maviri nemana.

2. Munda wekumanikidza unofanirwa kushandiswa pakati pechishandiso bhodhi uye yekutanga electrolytic board kuitira kuti kumanikidza mubhodhi rekutonga kunogona kugoverwa zvakaenzana. Nzvimbo dzakakwirira dzemagetsi dziripo mubhodhi uye mubhodhi redunhu kuti rizadzwe dzichabatwa nemunda. Munda unogonawo kubatanidza tembiricha kubva kunze kusvika pakati. Saka, ukobvu pakati pebhodhi rekutonga uye bhodhi rekutonga rakabatana.

3. Bhodhi rinofanira kunge rakagadzirwa nemucheka mutete weTACBOND unopiwa nemutengesi. Chenjerera kudzivirira kusvibiswa paunenge uchicheka zvidimbu zvitete uye stacking. Zvinoenderana nedhizaini dhizaini uye kuzadza zvinodiwa, 1 kusvika 3 yakatetepa yekunamatira maseru inodiwa. Nzvimbo inozadzwa uye zvinodiwa dielectric zvinoshandiswa kuverenga iyo 0.0015 ″ (38 micron) pepa zvinodiwa. Inokurudzirwa kushandisa simbi yakachena kana aluminium mirror mahwendefa pakati pelaminates.

4. Kuti ubatsire mukutsvaira, kurapwa kwevacuum kunoitwa kwemaminitsi makumi maviri vasati vapisa. Vacuum inochengetedzwa mukati mekutenderera. Kubvisa mhepo kuchabatsira kuve nechokwadi kuti dunhu rakaputirwa.

5. Isa thermocouple munzvimbo yekutenderera yepakati ndiro kuona tembiricha yekutarisa uye kutenderera kwakakodzera.

6. Iyo ndiro inogona kutakurwa pane inotonhora kana preheated press platen kuti itange. Kana iyo yekumanikidza munda isingashandisirwe muripo, kupisa kusimuka uye kutenderera kuchave kwakasiyana. Iyo yekupisa yekuisa pasuru haina kukosha, asi inofanirwa kudzorwa zvakanyanya sezvinobvira kuderedza gaka pakati pekunze nepakati nzvimbo. Kazhinji, mwero wekupisa uri pakati pe12-20oF/min (6-9°C/min) kusvika 425oF (220°C).

7. Kana uchinge watakurwa mukudhinda, kumanikidzwa kunogona kushandiswa pakarepo. Kudzvanywa kuchasiyanawo nehukuru hwe control panel. Inofanirwa kudzorwa mukati mehuwandu hwe100-200psi (7-14bar).

8. Chengetedza tembiricha yekutsikirira inopisa pa425oF (230°C) kwemaminitsi angangoita gumi nemashanu. Tembiricha haifanire kudarika 15oF (450°C).

9. Munguva yekugadzira lamination, kuderedza nguva yekusava nemamiriro ekudzvinyirira (senguva yekufambisa kubva kune inopisa inopisa kusvika kune inotonhora). Chengetedza mamiriro ekudzvinyirira kusvikira kudzvinyirira kuri pasi pe200oF (100 ° C).
