Njira yowerengera masamba = kutalika kwa tsamba lankhondo / kutalika kwa m'mphepete
Fakitale ya board board ya batri imakuphunzitsani momwe mungapewere nkhondo ya board board:

1. Kapangidwe kauinjiniya: makonzedwe a prepreg ya interlayer ayenera kugwirizana;gulu lalikulu la magawo ambiri ndi prepreg agwiritse ntchito zomwezo za omwe amapereka;malo akunja azithunzi za C / S ayenera kukhala pafupi momwe angathere, ndipo ma gridi odziimira okha angagwiritsidwe ntchito;

2. Chophika chophika musanadulire
Nthawi zambiri madigiri 150 kwa maola 6-10, chotsani chinyezi mu bolodi, pitilizani kuchiritsa utomoni, ndikuchotsa kupsinjika mu bolodi;kuphika bolodi musanadulidwe, kaya wosanjikiza wamkati kapena mbali zonse zikufunika!

3. Yang'anani mbali ya warp ndi weft ya pepala lochiritsidwa musanasanjike bolodi la multilayer:
Chiwerengero cha warp ndi weft shrinkage ndi chosiyana.Samalani njira yokhotakhota komanso yokhotakhota musanadulire pepala lokonzekera;tcherani khutu ku njira yokhotakhota komanso yokhotakhota podula bolodi loyambira;kawirikawiri njira yochiritsira mapepala ndi njira yozungulira;mbali yayitali ya laminate yamkuwa ndi njira yozungulira;10 zigawo 4OZ Mphamvu wandiweyani mkuwa mbale

4. Laminating wandiweyani kuthetsa nkhawa, ozizira kukanikiza pambuyo kukanikiza bolodi, chepetsa burrs;

5. Chophika chophika musanabowole: madigiri 150 kwa maola 4;

6. Ndibwino kuti musamatsuke mbale yopyapyala ndi makina, ndipo kuyeretsa mankhwala kumalimbikitsidwa;zida zapadera zimagwiritsidwa ntchito panthawi ya electroplating kuti mbale isapindike ndi kupindika

7. Mukapopera malata, muziziziritsa mwachibadwa kuti musamatenthetse bwino pamwala wansabwe kapena mbale yachitsulo kapena muziyeretsa mukazizirira pabedi loyandama;
