Awiri zigawo gulu guluu
5. Kugwiritsa:
(1) Pretreatment: m'munsi zinthu kusanja, zomatira, molingana ndi gawo la wothandizira wamkulu (mkaka woyera) ndi kuchiritsa wothandizira (bulauni wakuda) 10: 1 chiŵerengero. Sakanizani guluu mofanana, ndipo guluu wosakaniza ayenera kugwiritsidwa ntchito mkati mwa 30 ~ 60 mphindi.
(2) kukula: kukula kuyenera kumalizidwa mu mphindi imodzi, guluu la nsalu ndi yunifolomu ndipo guluu womaliza ayenera kukhala wokwanira.
(3) zophatikizika: nthawi yokakamiza kuti ikhale yokwanira, mbale yophimbidwa mu miniti ya 1, mphindi 3 iyenera kukakamizidwa, nthawi yokakamiza 45 ~ 120 mphindi, nkhuni yapadera 2 ~ 4 hours. Mphamvu yamagetsi iyenera kukhala yokwanira, cork 500 ~ 1000kg / m2 , matabwa olimba 800 ~ 15000kg/m2.
(4) Pambuyo mankhwala: pambuyo mpumulo kukakamizidwa kukhala wathanzi, thanzi kutentha pamwamba 20 ℃, maola 24 akhoza mopepuka kukonzedwa (maona, planer), maola 72 pambuyo processing kwambiri, pa nthawi kupewa kuwala kwa dzuwa ndi mvula yonyowa.

2, Kukaniza madzi bwino
3, Wokhazikika m'chilengedwe
Kuchuluka kwa ntchito
Ndi oyenera jigsaw kugwirizana kwa zinthu sanali structural ndi zipangizo structural.

Malangizo
1, Pretreatment: Chinyezi cha nkhuni chiyenera kuyendetsedwa pakati pa 8-12%;chomangira maziko pamwamba ayenera kukhala yosalala ndi lathyathyathya, popanda warpage, fumbi, mafuta, etc.
2, Kukula: wothandizila waukulu: kuchiritsa wothandizira (10: 1) chiŵerengero kusanganikirana ayenera mokwanira akuyambitsa kwa mphindi 3-5, mpaka yunifolomu.Guluu litakonzedwa, liyenera kugwiritsidwa ntchito mkati mwa maola 1-2.Kuphulika ndi kuwonjezereka kwa voliyumu kumatha kuchitika pakagwiritsidwa ntchito, zomwe ndizochitika zachilendo.Mukhoza kupitiriza kugwiritsa ntchito pambuyo poyambitsa pang'ono.
3, Kuchiritsa: Nthawi yokakamiza nthawi zambiri imakhala maola 2-4, kutengera kutentha
ndi chinyezi cha malo omanga.
Kusamalitsa
1.Base kusanja zinthu ndizofunikira:
Muyezo wa Flatness: ± 0.1mm Mulingo wamadzimadzi: 8% -12%;
2. Gawo la guluu ndilofunika kwambiri:
Wothandizira wamkulu (woyera) ndi wothandizira (wofiira wakuda) amasakanikirana ndi chiwerengero cha 100: 10 molingana ndi chiŵerengero chofanana;
3. Sakanizani guluu mofanana:
Gwiritsani ntchito choyambitsa mobwerezabwereza kuti mutenge colloid nthawi 3-5, popanda madzi a bulauni.Njira yothetsera guluu iyenera kugwiritsidwa ntchito mkati mwa mphindi 30-60;
4. Liwiro lakugwiritsa ntchito guluu ndilothamanga komanso lolondola:
Ntchito ya glue iyenera kumalizidwa mkati mwa mphindi imodzi.Guluu ayenera kukhala yunifolomu ndipo guluu kumapeto ayenera kukhala okwanira.
5.Kupanikizika nthawi iyenera kukhala yokwanira
Ma board okutidwa amapanikizidwa mkati mwa mphindi imodzi, ndipo amayenera kupanikizidwa mkati mwa mphindi zitatu.Nthawi yokakamiza ndi mphindi 45-120, ndipo nkhuni zolimba ndi maola 2-4;
6, kuthamanga kuyenera kukhala kokwanira:
Kuthamanga: softwood 500-1000kg /㎡matabwa olimba 800-15000kg /㎡;
7, pambuyo decompression kukhala ndi thanzi:
Kutentha kwa thanzi kumakhala pamwamba pa 20 ° C, kumatha kukonzedwa mopepuka (kuwonedwa, kukonzedwa) mu maola 24, ndipo kumatha kukonzedwanso mu maola 72.Pewani kuwala kwa dzuwa ndi mvula panthawiyi;
