Chii chinonzi plywood?
Zviri mukati
Mapuranga emapuranga kana "mashizha" ane matatu kana anopfuura akatetepa akaturikidzana ehuni hwepanyama hwakanamirwa pamwechete.
Iwo machira anozivikanwa se "layers", saka zita rekuti "plywood". Sezvo mutemo, iyo yakawanda yeplywood, iyo yakawanda mitsara iyo ine.
Icho chinhu chakasiyana-siyana chine huwandu hukuru hwemashandisirwo, kubva pamadziro uye pasi pekuvhara kusvika kune kongiri mold, yedhizaini fenicha uye kurongedza.
Plywood yakasimba zvakanyanya kupfuura mamwe ehuni-based sheet zvinhu senge medium density fibreboard (MDF).
Ona peji yedu Chii chinonzi MDF?, kuti uwane rumwe ruzivo nezve Medium Density Fibreboard.
Simba replywood rinokonzerwa nekuti kutungamira kwemafibhi ega ega ega kunochinjana maererano nezvikamu zviri pedyo.
Kutenderedzwa kwegwara rezviyo kwechikamu chimwe nechimwe, kunonzi kuyambuka tsanga, kunowanzoita madhigirii makumi mapfumbamwe (kurudyi kona). Izvi zvinoreva kuti zviyo zveimwe neimwe layer inotungamirwa munzira imwechete, uye iyo layer inotariswa pakona ye90 degree pakati pavo. Nekudaro, kona yekutenderera inogona kunge yakaderera se90 madhigirii. Mune mamwe mapuranga akakora, mitsara minomwe inogona kurongwa munhevedzano pamakona e30, 0, 30, 60, 90, 120, uye 150 madhigirii).
Kutenderedza zviyo kune zvakawanda zvakanakira. Izvi:
Inoderedza mukana wekutsemuka kana mapepa akarovererwa kumicheto
Inoderedza kuwedzera uye shrinkage kuti zvirinani dimensional kugadzikana
Inopa plywood simba rinoenderana mumativi ese mubhodhi.

Thinner plywood inowanzoshandiswa mukugadzira modhi, uye vamwe vanyori vanopenda pairi mushure mekuipenda nepurasita, chisimbiso chinopa nzvimbo yakati shwaka inobata pendi zvakanaka.
Yakagadzirirwa Zvinangwa Zvinokosha
Mhando dzakasiyana dzeplywood dzakagadzirirwa chinangwa chaicho. Semuenzaniso, plywood yakasimba yakaitwa kubva kumahogany uye / kana birch yakashandiswa mukuvaka imwe ndege yeHondo Yenyika II, nepo marine plywood yakagadzirwa kubva kune yakasimba chiso uye mukati mevheni ine hurema hushoma inoita zviri nani mumamiriro emvura uye munyoro.
Mamiriro
Masimba
Plywood yakasimba, kazhinji inoshingirira kukuvadzwa, yakareruka, uye iri nyore kucheka uye "kushanda" nemidziyo.
Iyo yakanaka kwazvo semashizha ekugadzira kana kuvhara hombe, yakatsetseka, yakatsetseka kana kunyange maumbirwo akadai semadziro, pasi, mamwe marudzi ematenga nemidziyo mikuru.
Inobatsira kubasa rakaoma
Mamwe marudzi eplywood akakodzera kune mamwe mabasa akaoma, akadai sekugadzira mienzaniso, mapuzzles emapuranga, uye mabhokisi maduku.
Zvikwangwani zvakakura zvinokurumidza kuvhara nzvimbo huru
Nekuti plywood inowanikwa mumapaneru akakura, nzvimbo dzakakura dzinogona kuvharwa neashoma epamucheto akabatana, uye yakafara sarudzo yehukobvu inoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa kubva kune gobvu masherufu kusvika kune yakaonda kupfekedza.
Plywood inogadzirwa sei?
Kugadzirwa kweplywood kunowanzoda matanda anonzi "hullers" ayo akakura muhupamhi uye akatwasuka kupfuura avhareji gidhi kubva kune iyo huni inotemwa.
Makwati anobviswa peeler isati yapisa uye yakanyoroveswa kwemaawa gumi nemaviri kusvika makumi mana isati yachekwa.
Inobva yaiswa mumushini muhombe wekupeya uye wotenderedzwa uchitenderedza axis yayo refu ...
… nepo blade refu ichipatsanura shizha rinoramba riripo kana dhiri kubva parogi. 
Pepa refu rinochekwa kuita zvidimbu zvehurefu nehupamhi hwepakutanga, uye mapeji acho anotariswa kuti akakanganisa. 
Iwo mataira anobva atsikirirwa uye anonamirwa pamwe chete, uye mapuranga anobuda anochekwa kusvika kune yawo yekupedzisira.
Kushanda kwekupedzisira kunowanzo kugaya - kuenzana - mapuranga. Mamwe mapuranga akaputirwa (senge melamine kana acrylic) uye mipendero yawo yakavharwa.
Ndeapi marudzi eplywood?
Rudzi rweplywood rwakakura kwazvo. Anotevera mamwe emhando huru dziripo. Taura nevatengesi vako vekuvaka kana kutarisa pamhepo kana iwe uchitsvaga chimwe chinhu chakanyanya kuenderana nechaidiwa.

Semuenzaniso, mhando dzebirch plywood:
S kirasi (yepamusoro) - zvikamu zviduku chete uye maitiro
Giredhi BB (pakati) - akaiswa oval zvigamba zvinotsiva chero makuru mapfundo uye kuremara.
Giredhi WG (yakaderera) - yakavhurika kuremara pamapfundo madiki ane mamwe akagadziridzwa makuru mapfundo.
Kirasi C (yakaderera) - yakavhurika kuremara inobvumirwa
Kune zvakare Brazilian, Chilean, Finnish, Russian, Swedish uye akati wandei mamwe marudzi. Usati watenga, tarisa giredhi replywood kuti uve nechokwadi chekuti plywood inosangana nezvinodiwa zverimwe basa.
Ndezvipi zviyero zveplywood?
Pane zviyero zvakasiyana - European neBS (British Standards) - yeplywood inoshandiswa mumhando dzakasiyana dzekushandisa.
Semuyenzaniso, muchikamu chekuvaka, chiyero cheEuropean chemapuranga-akavakirwa mapaneru EN 13986 inoda plywood inoshandiswa muchikamu chekuvaka kuti isangane nerimwe remakirasi matatu ekuita mukati meEN 636, uye vatengesi vanofanirwa kupa humbowo hweizvi.
Iwo makirasi ekuita akavakirwa pakudzivirirwa kwehunyoro hweplywood inoshandiswa munzvimbo dzakasiyana dzezvivakwa zvakaita sematenga, partitions, pasi, uye matanda-akaumbwa ekunze madziro.
Mamwe marudzi anosanganisa yakanakisa kuramba kwemamiriro ekunze uye ekunze simba zvivakwa kuti isangane nemimwe miitiro yakadai seBS 1088 (plywood yekushandiswa mugungwa), nepo dhizaini kodhi kodhi BS 5268-2:2002 inoshanda kune simba replywood, rinoshandiswa mukuvaka basa. Iyo ipfungwa yakanaka kutarisa kana plywood yauri kutenga iri yeiyo chaiyo chiyero chekushandiswa kwakarongwa.
