OSBinamandla kune-plywood ekusheleni.Amanani e-shear, ngokuqina kwawo, cishe izikhathi ezi-2 ezinkulu kune-plywood.Lesi ngesinye sezizathu ezenza ukuthi i-osb isetshenziselwe amawebhu ama-I-joists enziwe ngokhuni.Nokho, ikhono lokubamba izinzipho lilawula ukusebenza ezinhlelweni zodonga lokugunda.

Kungakhathaliseki ukuthi uyakha, ulungisa kabusha, noma wenza nje ukulungisa okuthile, izikhathi eziningi udinga uhlobo lwe-sheathing noma ukufakwa ngaphansi kwephrojekthi.Kunezinketho eziningi ezitholakalayo ngale njongo, kodwa imikhiqizo emibili evame ukusetshenziswa kakhulu i-oriented strand board (OSB) kanyeipulangwe.Womabili amabhodi enziwe ngokhuni anama-glues nama-resin, afika ngobukhulu obuningi, futhi angasetshenziswa ngezinjongo ezihlukahlukene.Kodwa ngayinye ayifanele ngempela yonke iphrojekthi.Sibeka umehluko phakathi kwabo ngezansi ukuze wenze isinqumo unolwazi mayelana nokuthi iyiphi ezosebenzela iphrojekthi yakho.

Indlela Enziwa Ngayo

I-OSB ne-plywood zakhiwe ngezingcezu ezincane zokhuni futhi ziza ngamashidi amakhulu noma amaphaneli.Nokho, yilapho ukufana kuphela khona.I-plywood yenziwe ngezingqimba eziningi zokhuni oluncane kakhulu, olubizwa ngokuthi ama-plys, acindezelwe kanye neglue.Ingase inikezwe i-veneer top of hardwood, kuyilapho izingqimba zangaphakathi zenziwe nge-softwood.

I-OSB yenziwe ngezingcezu eziningi ezincane zokhuni oluqinile nokhuni oluthambile oluxutshwe ndawonye ngemicu.Ngenxa yokuthi izingcezu zincane, amashidi e-OSB angaba makhulu kakhulu kunamashidi e-plywood.Nakuba i-plywood ivame ukuba ngamafidi angu-6 eshidini, i-OSB ingase ibe nkulu kakhulu, ifike kumafidi angu-12 ishidi ngalinye.

Ukubukeka

I-Plywoodingaba nezitayela eziningi ezahlukene kanye nokubukeka.Isendlalelo esiphezulu ngokuvamile siwukhuni oluqinile futhi lungase lube yinoma iyiphi inombolo yezinkuni ezifana ne-birch, beech, noma i-maple.Lokhu kusho ukuthi ishidi le-plywood lithatha ukubonakala kwezinkuni eziphezulu.I-plywood eyenziwe ngale ndlela iklanyelwe ukwakha amakhabethe, amashalofu, nezinye izinto lapho ukhuni lubonakala khona.

I-Plywood ingase yenziwe ngamapulangwe aphansi asezingeni eliphansi ongqimba lwawo oluphezulu.Kulokhu, ingase ibe namafindo noma indawo embi.Le plywood ngokuvamile isetshenziswa ngaphansi kwempahla eqediwe, njengethayela noma i-siding.

I-OSB ngokuvamile ayinayo ingaphezului-veneer .Yenziwe ngemicu eminingi noma izingcezu zokhuni ezincane ezicindezelwe ndawonye, ​​okwenza ibe lukhuni.I-OSB ayisetshenziselwa izindawo eziqediwe ngoba ayikwazi ukuphatha upende noma ukungcolisa ngendlela i-hardwood plywood engakwazi ngayo.Ngakho-ke, ngokuvamile ifakwa ngaphansi kwento yokuqeda, njenge-siding.

Ukufakwa

Ngokuphathelene nokufakwa kwesakhiwo sokuphahla noma ukuphahla, i-OSB ne-plywood zifana kakhulu ekufakweni.Umehluko kuphela ukuthi i-OSB iguquguquka kancane kune-plywood, enezinzuzo kanye nokubi kuye ngesilungiselelo nebanga phakathi kwama-joists ahlanganiswayo.

Kuzo zombili izimo, impahla ilinganiswa, ibekwe endaweni ngokumelene nama-joists, futhi ibethelwe phansi ngokuvikelekile.

Ukuqina

I-OSB ne-plywood ziyahlukahluka ngokuya ngokuqina.OSB imunca amanzi kancane kancanekune-plywood, engaba nenzuzo ezindaweni ezinomswakama ophansi.Nokho, lapho selimunce amanzi, liyoma kancane kancane.Iphinde ijike noma ikhukhumale ngemva kokumuncwa kwamanzi futhi ngeke ibuyele esimweni sayo sasekuqaleni.

I-Plywood imunca amanzingokushesha okukhulu, kodwa futhi yoma ngokushesha.Lapho seyomile, maningi amathuba okuba ibuyele esimweni sayo esivamile.Amaphethelo e-Plywood nawo amelana nomonakalo kangcono kune-OSB, engaqhekeka futhi ihlakazeke phezu komthelela futhi ngokuhamba kwesikhathi.

I-OSB inzima kune-plywood futhi, lapho ivikelwe kahle futhi inakekelwa, ngokuvamile izolala isicaba.I-OSB nayo ihambisana kakhulu kuneplywood.I-plywood itholakala kuma-plys amaningi namazinga ahlukene wekhwalithi.I-OSB ivamise ukungaguquguquki ebhodini lonke, okusho ukuthi okubonayo yilokho okutholayo.

I-plywood ne-OSB ngokuvamile zibhekwa njengamandla omthwalo ofanayo.Kodwa-ke, njengoba i-plywood isinesikhathi eside, ibonise ukuthi ingahlala iminyaka engu-50 noma ngaphezulu ekufakweni.I-OSB ayinawo umlando ofanayo ngoba isimakethwe cishe iminyaka engama-30.Irekhodi eliqinisekisiwe le-plywood livame ukuholela abanye abantu ukuthi bakholelwe ukuthi umkhiqizo ohlala njalo futhi ohlala isikhathi eside, kodwa lokhu akulona iqiniso ngempela.Izinhlobo ezintsha ze-OSB, ezithathwe njengezingangeni manzi, kungenzeka zihlale isikhathi eside njenge-plywood ezimeni ezifanayo.

Uma isetshenziswa ngaphansi kwe-flooring njenge-substrate, i-plywood ngokuvamile ibhekwa njengento engcono kakhulu.I-OSB inyakaza ngaphezu kweplywood.Uma isetshenziswa ngaphansi kwe-tile, ingakhala uma inyathela kahle kakhulu, futhi okubi kakhulu, ingabangelai-grout noma i-tile ngokwayo ukuze iqhekeke.Ngaleso sizathu, i-plywood ivamise ukuba yi-substrate enconyiwe uma kudingeka i-substrate yokhuni.

Ukukhathazeka Kwemvelo

Kule mikhiqizo emibili, i-OSB ithathwa njengenketho eluhlaza.Ngenxa yokuthi i-OSB yenziwe ngezingcezu eziningi zokhuni ezincane, ingadalwa kusetshenziswa izihlahla ezinobubanzi obuncane, ezikhula ngokushesha futhi ezingafuywa.

Nokho, i-plywood, idinga ukusebenzisa izihlahla ezinobubanzi obukhulu, ezibe sezisikwa ngokuzungezayo ukuze zikhiqize izingqimba ezidingekayo.Izihlahla ezinkulu ezinobubanzi obufana nalezi zithatha isikhathi eside ukukhula futhi kufanele zivunwe emahlathini asekhulile, okwenzaipulangweainketho encane eluhlaza.

I-OSB isakhiqizwa kusetshenziswa i-formaldehyde, nokho, kuyilapho i-plywood kufanele ikhiqizwe ngaphandle kwaleli khemikhali ngokwemithetho emisha yezemvelo ngonyaka.I-Hardwood plywood isivele itholakala ngeglue esekelwe ku-soy nezinye izinto ezingakhiphi i-urea-formaldehyde emoyeni.Nakuba kungenzeka ukuthi i-OSB izolandela, maduzane kuzokwazi ukuthola i-plywood ngaphandle kwe-formaldehyde yonke indawo, kuyilapho ukuthola i-OSB ngaphandle kwaleli khemikhali kungase kube nzima kakhulu.

I-Resale Value

Akukho okubalulekile okunomthelela wangempela enanini lokuthengisa kabusha lekhaya.Zombili izinto ezisetshenziswayo zithathwa njengesakhiwo uma zisetshenziswa ngokuqhathaniswa.Uma isetshenziswa ngokwesakhiwo, izinto ezisetshenziswayo zifihliwe, futhi ngokuvamile azidalulwa ngesikhathi sokuthengisa, okusho ukuthi azinawo umthelela ezindlekweni.
