Apha, abavelisi beplywood baseTshayina bayakukhumbuza ukuba xa uthenga iplywood, kubalulekile ukufumana umenzi wemithombo yokhetho olungakumbi, olukhuselekileyo kunye noqoqosho.
Yintoni iplywood
IPlywoodyenye yeemveliso zephaneli ezenziwe ngamaplanga ezisebenza ngeendlela ezininzi nezivunyiweyo ngokubanzi ezisetyenziswa kwiiprojekthi ezahlukeneyo zokwakha kwihlabathi jikelele. Idalwe ngokubopha i-resin kunye namaphepha e-veneer yokhuni ukwenza izinto ezidibeneyo ezithengiswa kwiipaneli. Ngokuqhelekileyo, iimpawu zeplywood zijongene nemigangatho yomgangatho ophezulu kuneentsimbi eziphambili. Umsebenzi ophambili wemigangatho engundoqo kukunyusa ukwahlukana phakathi kweengqimba zangaphandle apho uxinzelelo lokugoba luphezulu, ngaloo ndlela kwandisa ukuchasana nokugoba amandla. Oku kwenza iplywood ibe lolona khetho lubalaseleyo kwizicelo ezifuna amandla kunye nokuguquguquka.
Intshayelelo kwiinkqubo zemveliso
I-Plywood, eyaziwa ngokuba yibhodi ye-multi-layer, ibhodi ye-veneer, okanye ibhodi engundoqo, yenziwe ngokusika i-veneers ukusuka kumacandelo e-log kwaye emva koko i-gluing kunye nokutshisa icinezele kwiileya ezintathu okanye ngaphezulu (ezingaqhelekanga) zebhodi. Inkqubo yokuvelisa iplywood ibandakanya:
Ukusika izigodo, ukuxobula, kunye nokusika; Ukomisa ngokuzenzekelayo; Ukudibanisa ngokupheleleyo; I-Gluing kunye ne-billet indibano; Ukucinezela okubandayo kunye nokulungiswa; Ukucinezela okushushu kunye nokunyanga; Ukusarha, ukukrwela, nokusarha; Ukulungiswa izihlandlo ezithathu, ukulungisa izihlandlo ezithathu, isarha izihlandlo ezithathu, isarha izihlandlo ezithathu; Ukuzalisa; Ukuhlolwa kwemveliso egqityiweyo; Ukupakishwa kunye nokugcinwa; Ezothutho
Ukugawula iLog kunye nokuPeeling
I-peeling iyona nto ibalulekileyo kwikhonkco yokuvelisa i-plywood, kwaye umgangatho we-peeling veneer uya kuchaphazela ngokuthe ngqo umgangatho weplywood egqityiweyo. Izigodo ezinobubanzi obungaphezulu kwe-7cm, ezifana ne-eucalyptus kunye ne-miscellaneous pine, ziyasikwa, zihlulwe, kwaye zihlanjululwe kwii-veneers ezinobunzima obungaphantsi kwe-3mm. I-peneers ehlanjululweyo inobunzima obuhle obufanayo, ayifuni ukungena kwiglue, kwaye ineepateni ezintle ze-radial.
Ukomisa ngokuzenzekela
Inkqubo yokomisa ihambelana nokumila kweplywood. I-peneers ehlanjululweyo kufuneka yomiswe ngexesha ukuze kuqinisekiswe ukuba umswakama wabo ufikelela kwiimfuno zokuvelisa i-plywood. Emva kwenkqubo yokumisa ngokuzenzekelayo, umgangatho womswakama we-veneers ulawulwa ngaphantsi kwe-16%, i-warpage yebhodi incinci, akulula ukuyilungisa okanye i-delaminate, kunye nokusebenza kokusebenza kwee-veneers kugqwesileyo. Xa kuthelekiswa nendlela yokomisa yendalo yendalo, inkqubo yokomisa ngokuzenzekelayo ayichaphazeli imozulu, ixesha lokumisa lifutshane, umthamo wokomisa imihla ngemihla unamandla, ukuphumelela kokumisa kuphezulu, isantya sikhawuleza, kwaye umphumo ungcono.
I-Splicing epheleleyo, i-Gluing, kunye neNdibano ye-Billet
Indlela yokudibanisa kunye ne-adhesive esetyenzisiweyo inquma ukuzinza kunye nokulungeleka kokusingqongileyo kwebhodi yeplywood, eyona nto ibaluleke kakhulu kubathengi. Indlela yamva nje yokudibanisa kwishishini yindlela epheleleyo yokudibanisa kunye nesakhiwo se-toothed splicing. Iimvumba ezomileyo kunye ne-peeled veneers zixutywe kwibhodi enkulu epheleleyo ukuze kuqinisekiswe ukuqina okulungileyo kunye nokuqina kwee-veneers. Emva kwenkqubo ye-gluing, i-veneers ihlelwe ngendlela ye-crisscross ngokwesikhokelo somthi wengqolowa ukwenza i-billet.
Ukucinezela Okubandayo kunye nokulungiswa
Ucinezelo olubandayo, olukwabizwa ngokuba lucinezelo lwangaphambili, lusetyenziselwa ukwenza ukuba i-veneers inamathele enye kwenye, ithintele iziphene ezifana nokufuduswa kwe-veneer kunye nokupakishwa kwebhodi engundoqo ngexesha lenkqubo yokuhambisa kunye nokuphatha, ngelixa kwandisa ukuguquguquka kweglu ukuze kuququzelele i-glue. ukubunjwa kwefilimu yeglue elungileyo kumphezulu we-veneers, ukuphepha i-phenomenon yokusilela kweglue kunye neglue elomileyo. I-billet ithuthelwa kumatshini wangaphambili kwaye emva kwemizuzu engama-50 yokucinezela okubandayo ngokukhawuleza, ibhodi engundoqo yenziwe.
Ukulungiswa kwebhilethi yebhodi yinkqubo eyongezelelweyo phambi koxinzelelo olushushu. Abasebenzi balungisa umaleko womphezulu webhodi engundoqo ngokwemaleko ukuqinisekisa ukuba umphezulu wayo ugudile kwaye umhle.
Ukucinezela okushushu kunye nokuNyanga
Umatshini oshushu oshushu ungomnye wezixhobo ezibaluleke kakhulu kwinkqubo yokuvelisa iplywood. Ukucinezela okushushu kunokuthintela ngokufanelekileyo iingxaki zokubunjwa kweqamza kunye ne-delamination yendawo kwiplywood. Emva koxinzelelo olushushu, i-billet kufuneka ipholile malunga nemizuzu ye-15 ukuqinisekisa ukuba isakhiwo semveliso sizinzileyo, amandla aphezulu, kwaye ugweme ukuguqulwa kwe-warping. Le nkqubo yinto esiyibiza ngokuba lixesha "lokunyanga".
Ukusarha, ukukrwela, kunye nokuSanda
Emva kwexesha lokunyanga, i-billet iya kuthunyelwa kumatshini wokuthunga ukuba unqunywe kwiinkcukacha ezihambelanayo kunye nobukhulu, ngokulinganayo kunye nokucoceka. Emva koko, umphezulu webhodi uyakhunyulwa, womiswe, kwaye ufakwe isanti ukuze kuqinisekiswe ukugudiswa ngokubanzi, ukuthungwa okucacileyo, kunye neglosi elungileyo yebhodi. Ukuza kuthi ga ngoku, umjikelo wokuqala weenkqubo ezili-14 zokuvelisa inkqubo yokuvelisa iplywood sele igqityiwe.
Ukulungisa izihlandlo ezithathu, ukulungisa izihlandlo ezithathu, isarha izihlandlo ezithathu, isarha izihlandlo ezithathu
I-plywood ekumgangatho ophezulu kufuneka ihambe kwiinkqubo ezininzi zokucolisa. Emva kwesanti yokuqala, i-plywood iya kufakwa kwinqanaba lesibini, ukucinezela okubandayo, ukulungiswa, ukucinezela okutshisayo, ukuthungatha, ukukrazula, ukomisa, ukuthunga, kunye ne-scraping, iinkqubo ezi-9 zizonke kumjikelo wesibini.
Okokugqibela, i-billet incamathelwe ngobuchwephesha obugqwesileyo kunye nobuhle bomthi womphezulu, umphezulu we-mahogany, kunye neplywood nganye iphinda icinezele ucinezelo lwesithathu olubandayo, ukulungiswa, ucinezelo olushushu, ukukrwela, ukugawula, ukusarha, kunye nezinye iinkqubo ezili-9. Itotali "ezithathu zokucinezela, ukulungiswa ezintathu, isarha ezintathu, sandings ezintathu" 32 iinkqubo zokuvelisa, umphezulu webhodi ukuba tyaba, sakhiwo ezinzile, unomlinganiselo omncinane deformation, kwaye intle kwaye ihlala ixesha elide iveliswa.
Ukuzaliswa, Ukuhlelwa kweMveliso egqityiweyo
I-plywood eyenziweyo iyahlolwa kwaye izaliswe emva kokuhlolwa kokugqibela kwaye ihlelwe. Ngovavanyo lwezenzululwazi lobunzima, ubude, ububanzi, isiqulatho sokufuma, kunye nomgangatho womphezulu, kunye neminye imigangatho, ukuqinisekisa ukuba iplywood nganye eveliswayo ikumgangatho ofanelekileyo nozinzileyo, ngowona mgangatho ubalaseleyo womzimba kunye nowokulungisa.
Ukupakishwa kunye noGcino
Emva kokuba imveliso egqityiweyo ikhethiwe, abasebenzi bapakisha iplywood kwindawo yokugcina ukuphepha ilanga nemvula.
TONGLI TIMBER
I-plywood isetyenziselwa ntoni?
IPlywood luhlobo oluqhelekileyo lwebhodi olusetyenziswa kumashishini ahlukeneyo. Zahlulwe ngokweendidiiplywood eqhelekileyokwayeiplywood ekhethekileyo.
Usetyenziso oluphambili lweiplywood ekhethekileyozezi zilandelayo:
1.IBakala lokuqala lilungele imihombiso yezakhiwo ezikumgangatho ophezulu, ifanitshala yodidi oluphakathi ukuya koluphezulu, neekhaseji zezixhobo zombane ezahlukeneyo.
2.IBakala lesibini lilungele ifanitshala, ulwakhiwo jikelele, isithuthi, nokuhombisa iinqanawa.
3.IBakala lesithathu lilungele ukulungiswa kwesakhiwo esikumgangatho ophantsi kunye nezinto zokupakisha. Ibanga elikhethekileyo lilungele imihombiso yezakhiwo eziphezulu, ifenitshala ephezulu, kunye nezinye iimveliso ezineemfuno ezizodwa.
Iplywood eqhelekileyoihlelwa kwiKlasi yoku-I, iKlasi yesi-II, kunye neKlasi ye-III ngokusekwe kwiziphene ezibonakalayo ezibonakalayo kunye neziphene zokulungisa kwiplywood emva kokulungiswa.
I-1.I-Class I plywood: I-plywood ye-Weather-resistant, ehlala ixesha elide kwaye inokumelana nokubilisa okanye unyango lwe-steam, olulungele ukusetyenziswa kwangaphandle.
I-2.I-plywood ye-Class II: I-plywood engenamanzi, enokuthi ifakwe emanzini abandayo okanye ifakwe emanzini ashushu ashushu, kodwa ayifanelekanga ukubilisa.
I-3.I-Plywood yeklasi ye-III: I-plywood enganyangekiyo yokufuma, ekwazi ukujamelana nokucwiliswa kwamanzi abandayo ixesha elifutshane, elilungele ukusetyenziswa kwangaphakathi.
