Njira yopanga apamwamba epoxy glass fiber board

A. Kukonzekera pamwamba ndi chithandizo cha Epoxy galasi nsalu laminate mankhwala

1. Pambuyo pa mkuwa wopangidwa ndi mawonekedwe ndi okhazikika kuti apange dera, yesetsani kuchepetsa chithandizo ndi kukhudzana ndi PTFE pamwamba. Wogwira ntchitoyo ayenera kuvala magolovesi oyera ndikuyika filimu ya interlayer pa bolodi lililonse kuti apite ku njira ina.

2. The anazikika PTFE pamwamba ali roughness zokwanira kwa kugwirizana. Kumene mapepala otsekedwa kapena ma laminates osaphimbidwa adzamangidwa, tikulimbikitsidwa kuti tigwiritse ntchito pamwamba pa PTFE kuti apereke chomangira chokwanira. Zomwe zimagwiritsidwa ntchito pokonzekera pth zitha kugwiritsidwanso ntchito pamankhwala apamwamba. Limbikitsani plasma etching kapena sodium-containing chemical reagents, monga FluroEtch®byActon, TetraEtch®byGore, ndi Bond-Prep®byAPC. Tekinoloje yeniyeni yoyendetsera ntchito imaperekedwa ndi wogulitsa.

3. Chithandizo chapamwamba cha mkuwa chiyenera kuonetsetsa kuti mgwirizanowu ukhale wolimba kwambiri. Chithandizo chozungulira cha brown copper monoxide chimalimbitsa mawonekedwe apamwamba kuti athandizire kulumikizana kwamankhwala ndi zomatira za TacBond. Njira yoyamba imafuna chotsukira kuchotsa zotsalira ndi mafuta ochizira. Kenako, amakoka bwino mkuwa kuti apange malo amtundu umodzi. Makristalo a singano a brown oxide amakhazikika pagawo lomangira panthawi yoyatsira. Monga momwe zimakhalira ndi mankhwala, kuyeretsa kokwanira pambuyo pa sitepe iliyonse ya ndondomekoyi ndikofunikira. Zotsalira zamchere zidzalepheretsa kumamatira. Kutentha komaliza kuyenera kuyang’aniridwa ndipo pH iyenera kukhala pansi pa 8.5. Wowuma wosanjikiza ndi wosanjikiza ndikuwonetsetsa kuti pamwamba siipitsidwa ndi mafuta m’manja.

B. Kukuta ndi kuyanika

Kumangirira kovomerezeka (kukanikiza kapena kukanikiza) kutentha: 425°F (220°C)

Kuphika plies pa 1.250oF (100 ° C) kuchotsa chinyezi. Zigawozo zimasungidwa pamalo otetezedwa mwamphamvu ndipo zimagwiritsidwa ntchito mkati mwa maola 24.

2. Malo oponderezedwa ayenera kugwiritsidwa ntchito pakati pa bolodi la zida ndi bolodi loyamba la electrolytic kuti kupanikizika mu bolodi lolamulira kugawidwe mofanana. Madera okwera kwambiri omwe ali mu bolodi ndi pa bolodi lozungulira kuti adzazidwe adzatengedwa ndi munda. Munda ungathenso kugwirizanitsa kutentha kuchokera kunja kupita pakati. Choncho, makulidwe pakati pa bolodi lolamulira ndi gulu lolamulira ndilogwirizana.

3. Bolodi liyenera kukhala locheperako la TACBOND loperekedwa ndi wogulitsa. Samalani kuti mupewe kuipitsidwa podula magawo opyapyala ndi kutukuka. Malinga ndi kapangidwe ka dera komanso kudzaza zofunika, 1 mpaka 3 zomatira zoonda ndizofunikira. Malo oyenera kudzazidwa ndi zofunikira za dielectric zimagwiritsidwa ntchito kuwerengera zofunikira za pepala la 0.0015 ″ (38 micron). Ndi bwino kugwiritsa ntchito zitsulo zoyera kapena magalasi a aluminiyamu mbale pakati pa laminates.

4. Pofuna kuthandizira, chithandizo cha vacuum chimachitidwa kwa mphindi 20 musanayambe kutentha. Vacuum imasungidwa nthawi yonseyi. Kutulutsa mpweya kudzathandiza kuti dera likhale lopakidwa.

5. Ikani thermocouple m’dera lozungulira la mbale yapakati kuti muwone momwe kutentha kumayendera komanso kuzungulira koyenera.

6. mbale akhoza yodzaza pa ozizira kapena preheated atolankhani platen kuyamba. Ngati malo oponderezedwa sagwiritsidwa ntchito polipira, kukwera kwa kutentha ndi kufalikira kudzakhala kosiyana. Kulowetsa kutentha kwa phukusi sikofunikira, koma kuyenera kuyang’aniridwa momwe mungathere kuti muchepetse kusiyana pakati pa madera akunja ndi apakati. Nthawi zambiri, kutentha kumakhala pakati pa 12-20oF/min (6-9°C/min) mpaka 425oF (220°C).

7. Mukangodzaza muzosindikiza, kupanikizika kungagwiritsidwe ntchito nthawi yomweyo. Kupanikizika kudzasiyananso ndi kukula kwa gulu lolamulira. Iyenera kuyendetsedwa mkati mwa 100-200psi (7-14bar).

8. Sungani kutentha kwapakati pa 425oF (230 ° C) kwa mphindi zosachepera 15. Kutentha sikuyenera kupitirira 450oF (235°C).

9. Panthawi yopangira lamination, kuchepetsa nthawi yopanda kupanikizika (monga nthawi yochoka ku makina otentha kupita ku ozizira ozizira). Pitirizani kupanikizika mpaka kupanikizika kuli pansi pa 200oF (100 ° C).
