Plywood imhando yemapuranga akagadzirwa nemunhu anobatanidzwazve nekupenengura.
Plywood inogadzirwa nekucheka muhombe-nzvimbo mavheiri munzira yezvindori zvegore. Mushure mekuomeswa uye kusungirirwa, inogadzirwa maererano nechiyero che vertical mahogany grain orientation yezviyo zviri pedyo.
Huwandu hwemabhodhi epakati kazhinji inhamba isinganzwisisike yemateya, kazhinji matatu kusvika gumi nematatu, uye nhamba yakajairika yematanho anowanzo kuita matatu, matara mashanu, mapfumbamwe akaturikidzana, uye gumi nematatu (musika wekutengesa unowanzo kunzi matatu plywood, mashanu. plywood, mapfumbamwe plywood, Masendimita gumi nematatu). Veneer yekumberi yekunze kwekunze inonzi panhire yekumberi, kumashure kunonzi kuseri, uye mukati kunonzi core board.
Type 1 plywood ine mabhenefiti ekuramba kwemamiriro ekunze, kuvirisa mvura inofashaira, kusimba, kukwirira tembiricha kuramba, uye kusamira kwemhepo.
Aya marudzi maviri eplywood plywood isina mvura, inogona kunyikwa mumvura inotonhora uye inopisa mvura munguva pfupi.
Type 3 plywood is waterproof plywood, inogona kunyudzwa mumvura inotonhora kwenguva pfupi, iyo inokodzera tembiricha yemukati mukamuri. Fenicha uye zvinangwa zvekuvaka zvakazara;
Type 4 plywood plywood inodzivirira mwando, iyo inowanzoshandiswa mukati memba. Plywood inowanzoshandiswa inosanganisira birch, eucalyptus, uye poplar.
Plywood inonyanya kushandiswa mumamiriro ekunze, sekuvaka kushongedza kwekunze uye kongiri fomu. Mukushongedza, inonyanya kushandiswa mumasirin'i, masiketi emadziro, uye pasi liner.
Iyo yakakosha kuumbwa kweplywood
Kuti uvandudze anisotropy yehuni hwechisikigo zvakanyanya sezvinobvira, plywood ine yunifomu maitiro uye yakagadzikana chimiro. Kazhinji, plywood inofanira kutevera nheyo mbiri dzinokosha mukugadzirisa: imwe ndeyekuenzanisa; imwe yacho ndeyekuti ari padyo ne-single-board optical fibers ari perpendicular kune mumwe nemumwe.
Nheyo yekufananidza ndeyekuti plywood inodiwa pamativi ese epakati ndege ye symmetry yeplywood, zvisinei nemhando yehuni, ukobvu hweplywood, huwandu hwematanho, kutungamira kwefiber, uye humidity. zvemukati zvinofanirwa kuenderana kune mumwe nemumwe.
Mune plywood imwechete, miti imwe chete uye mavheji ekukora anogona kushandiswa, kana mavheji emhando dzakasiyana dzemiti uye makubvu anogona kushandiswa; zvisinei, chero maviri akaturikidzana akaenzana symmetrical veneer miti uye ukobvu pamativi ese epakati symmetry ndege yakafanana.
Kuti uite chimiro cheplywood chinosangana nepamusoro pemitemo miviri yepamusoro, nhamba yezvikamu zvinofanira kunge zvisinganzwisisike.
Nokudaro, plywood inowanzoparadzaniswa kuva zvidimbu zvitatu, zvidimbu zvishanu, zvidimbu zvinomwe uye zvimwe zvisinganzwisisiki.
Zita re plywood layer nderekuti: vheji yepamusoro inonzi tafura, mukati memukati inonzi core board; jira repamberi rinonzi panhizha, uye reshure rinodaidzwa kuti rear panel; mu core board, iyo fiber kutungamira inofanana nepaneru.
Inonzi refu core board kana yepakati-bhodhi.
Zvakanakira plywood
Zvakanakira plywood yakasimba kutakura kutakura, kwete nyore kukanganisa uye kukotama, kwete nyore kuputika, uye kuwedzera kudiki. Multilayer board ine kugona kwakanaka kuchinjika kune yemukati tembiricha uye humidity. Nzvimbo yepamusoro ye multilayer board ndeye huni hwepanyama. Mbeu yehuni iri pedyo nemasikirwo uye chimiro chikuru. Zvakanakira zveakawanda-layer board zviri nyore kugadzira. Kuenzaniswa nedanda rakasimba rehuni, akawanda-layer board inodzivirira kumwe kukanganiswa kwehuni hwepanyama, senge kundandama, hupamhi, deformation, uye kushomeka kwekumanikidza kuramba.
Multi-layer board anewo mukana mukuru pamusoro pehuni hwepanyama mumutengo. Sezvo mabhodhi e-multi-layer achiongorora zvakare uye kurongazve matanda, ane mari yakawanda kupfuura inodhura mapuranga emapuranga emapuranga.
Kuipa kwe multilayer board
Iyo yakawanda-layer board inogadzirwa neakasikwa huni core board kuburikidza nepamusoro tembiricha uye yakanyanya kudzvanywa muchina unopisa unonamatira. Naizvozvo, maererano nekuchengetedzwa kwezvakatipoteredza, pachave nekuburitswa kwe formaldehyde. Asi iri padyo nemapuranga echisikigo uye zvakare ndiyo inonyanya kushamwaridzana nemamiriro ekunze bhodhi rekugadzira.
Kuzivikanwa kweplywood yakanaka kana yakaipa
Kutanga, tarisa flatness yepaneti. Kubva panguva ino, tinogona kuona zvinhu zvemukati zvebhodhi. Patinotarisa pabhodhi, tinogona kuibata nemaoko edu tonzwa kana pane kusaenzana kupi nokupi. Kana iripo, zvinoreva kuti jecha repamusoro harina kunaka.
Pamwe zvinoreva kuti core board material haina kunaka uye zvinhu zvacho zvakatyoka. Muchidimbu, hazvikurudzirwi kutenga zvisina kuenzana.
Chechipiri, cherechedza pfungwa yehutungamiri hwebhodhi re multilayer. Iyo yakakora bhodhi, zviri nyore kuti uone kuiswa kweiyo yakawanda-layer board. Kana imwe neimwe mutsara yakagadzirwa ne monolithic zvinhu, zvidimbu zvichave zvakajeka uye hapazovi ne-cross-layer phenomenon. Kana zvinhu zvisina kunaka, pane zvakawanda zvakasara.
Nekuda kwekuita kwekumanikidza, iyo nhanho inozowedzera kuipa mushure mekudzvanya mumwe nemumwe.
