5. Tšebeliso:
(1) Pretreatment: lisebelisoa tsa motheo tsa boemo bo holimo, sekhomaretsi, ho ea ka karolo ea moemeli ea ka sehloohong (milky white) le ho phekola (sootho o lefifi) ka karolelano ea 10: 1. Hlohlelletsa sekhomaretsi ka mokhoa o ts'oanang, 'me sekhomaretsi se tsoakiloeng se lokela ho sebelisoa ka hare ho 30. ~ 60 metsotso.
(2) boholo: boholo bo lokela ho phethoa ka motsotso o le mong, sekhomaretsi sa lesela se tšoana le sekhomaretsi sa lesela la ho qetela se lokela ho lekana.
(3) motsoako: nako ea khatello e lekaneng, sejana se koahetsoeng ka metsotso ea 1, metsotso ea 3 e tlameha ho hatelloa, nako ea khatello ea metsotso e 45 ~ 120, lehong le khethehileng la 2 ~ lihora tsa 4. Matla a khatello a lokela ho lekana, cork 500 ~ 1000kg / m2 , lehong le thata 800 ~ 15000kg/m2.
(4) Ka mor'a phekolo: ka mor'a khatello ea khatello ea ho boloka bophelo bo botle, mocheso oa bophelo bo botle o ka holimo ho 20 ℃, lihora tse 24 li ka sebetsoa habobebe (saw, planer), lihora tse 72 ka mor'a ts'ebetso e tebileng, nakong ea ho qoba letsatsi le pula e nang le metsi.

Litaelo
1, Pretreatment: Mongobo oa patsi o lokela ho laoloa pakeng tsa 8-12%;bokaholimo ba motheo bo lokela ho ba boreleli le bo bataletseng, ntle le warpage, lerōle, oli, joalo-joalo.
2, Sizing: moemeli ea ka sehloohong: ho folisa moemeli (10: 1) ho kopanya karo-karolelano ho hloka ho hlohlelletsa ka botlalo metsotso e 3-5, ho fihlela junifomo.Ka mor'a hore sekhomaretsi se lokisoe, se lokela ho sebelisoa ka hare ho lihora tse 1-2.Li-bubble le ho atolosoa ha molumo ho ka etsahala nakong ea tšebeliso, e leng ntho e tloaelehileng.U ka tsoela pele ho sebelisa ka mor'a ho sisinyeha hanyenyane.
3, Ho phekola: Nako ea ho hatella hangata ke lihora tse 2-4, ho latela mocheso
le mongobo oa tikoloho ea kaho.
Mehato ya tlhokomelo
1.Base material leveling ke ya bohlokwa:
Boemo ba ho batalla: ± 0.1mm Tekanyetso ea metsi: 8% -12%;
2. Karolo ea sekhomaretsi e bohlokoa haholo:
Moemeli ea ka sehloohong (o mosoeu) le moemeli oa ho phekola (sootho o lefifi) o kopantsoe ka karolelano ea 100: 10 ho ea ka karolelano e lumellanang;
3. Hlohlelletsa sekhomaretsi ka ho lekana:
Sebelisa moferefere ho pheta-pheta colloid makhetlo a 3-5, ntle le mokelikeli o mosootho oa filamentous.Tharollo e tsoakiloeng ea sekhomaretsi e lokela ho sebelisoa ho fihlela metsotso e 30-60;
4. Lebelo la kopo ea glue le potlakile ebile le nepahetse:
Sekhomaretsi se lokela ho phethoa nakong ea motsotso o le mong.Sekhomaretsi se lokela ho ba se ts'oanang 'me sekhomaretsi qetellong se lokela ho lekana.
5.Nako ea khatello e lokela ho lekana
Liboto tse koahetsoeng li hatelloa hammoho nakong ea motsotso o le mong, 'me li tlameha ho hatelloa ka hare ho metsotso e 3.Nako ea ho hatella ke metsotso ea 45-120, 'me lehong le thata ke lihora tse 2-4;
6, khatello e lokela ho lekana:
Khatello: softwood 500-1000kg /㎡lehong le thata 800-15000kg /㎡;
7, ka mor'a decompression ho boloka bophelo bo botle:
Thempereichara ea bophelo bo botle e ka holimo ho 20 ° C, e ka sebetsoa hanyenyane (saw, planed) ka lihora tse 24, 'me e ka sebetsoa hape ka lihora tse 72.Qoba khanya ea letsatsi le pula nakong ea nako;
