A: Ibhodi le-MgOiyimpahla yokwakha eqinile, yekhwalithi ephezulu, engashi, esekelwe kumaminerali esetshenziselwa ukufaka esikhundleni se-plywood, amaphaneli osimende we-fiber, i-OSB, namabhodi odonga e-gypsum.Kungumkhiqizo oguquguqukayo ngokwedlulele ongasetshenziselwa ukwakhiwa kwangaphakathi nangaphandle.Yenziwe ngokuhlanganisa izakhi ezithile, okuhlanganisa i-magnesium nomoya-mpilo, okuholela ekusetshenzisweni okuqinile okufana nosimende.Izinhlanganisela ezifanayo zisetshenziswe amakhulu eminyaka ezakhiweni ezidume umhlaba wonke njenge-Great Wall of China, i-Rome's Pantheon, ne-Taipei 101.
A: Ibhodi le-MgOiyimpahla yokwakha eyingqayizivele, engabizi kakhulu etholakala kabanzi kulo lonke elase-US Umkhiqizo uklanyelwe ukubhekana nezinselelo zesakhiwo eziqinile abaklami bezakhiwo, osonkontileka, abafakeli, abakhi, nabathengi, okuhlanganisa ukumelana nomlilo, umswakama, isikhunta, isikhutha, nezinambuzane.
A: Ibhodi le-MgOiwumkhiqizo oguquguqukayo kakhulu ongasetshenziswa ezinhlelweni eziningi, ngaphakathi nangaphandle.

A: Amabhodi e-MgO ngokuvamile athengiswa ngamasayizi ajwayelekile angu-4× 8 amafithi 4× 10 izinyawo.Ubude bungenziwa ngezifiso phakathi kwamafidi angu-8 no-10.Izinketho ezihlukahlukene zokujiya ziyatholakala, kusukela ku-3mm kuya ku-19mm.
A: Yebo.Ibhodi le-MgOiphephile kunemikhiqizo eminingi yokwakha eqhathanisekayo.Iwumkhiqizo osuselwe kumaminerali owenziwe ngezithako ezingenabo ubuthi, okwazi ukuphinda usebenziseke kabusha, futhi amelana nesikhunta, isikhutha, kanye nezinto ezingezwani nazo, okuwenza ulungele abantu abangezwani nezinto ezithile noma isifuba somoya.
A: Ibhodi le-MgOinikeza izinzuzo eziningi zezindleko.Ngenxa yamandla nokuqina kwayo,Ibhodi le-MgOkwandisa isikhathi sokuphila kwezakhiwo ezifana nezindlu nezakhiwo.Izindleko ishidi ngalinye leIbhodi le-MgOAmaphaneli e-MgO anogqinsi olufanayo aphakeme kune-gypsum evamile kodwa ayaqhathaniswa noma angaphansi kwezinhlobo ezikhethekile, futhi ngokuvamile angaphansi kwemikhiqizo eminingi usimende.
A: Cha.Ibhodi le-MgOkuthathwa njengokumelana nomswakama;kodwa-ke, ngezikhathi zokuchayeka isikhathi eside, umswakama ungawuthinta, futhi uzonwetshwa nge-hydrothermal.Uma isetshenziswa ngaphandle, i-Magboard kufanele imbozwe noma ifakwe ukuze ivikeleke ezintweni.
A: Yenziwa ngokuhlanganisa umoya-mpilo ne-magnesium ngaphansi kokushisa nokucindezela, okuvame ukubizwa ngokuthi “MgO,” ngenxa yokwakheka kwayo kwamakhemikhali e-magnesium (uphawu lwamakhemikhali uMg) nomoya-mpilo (uphawu lwamakhemikhali O).I-MgO igaywa ibe yimpushana, bese ixutshwa namanzi ukuze kwakheke into enamathelayo efana nosimende.Ibhodi le-MgOfuthi iqukethe ezinye izingxenye, kodwa i-MgO iyingxenye eyinhloko.
I-magnesium ehlanzekile, ngendlela eluhlaza, iyavutha, kodwa i-MgO ayinakushi ngokuphelele futhi isetshenziselwa ukuvimbela umlilo.
EyethuIbhodi le-MgOamabhodi e-magnesium oxide anokuqukethwe kwe-chloride okulawulwa ngokuqinile phakathi nenqubo yethu yokukhiqiza, okulinganiselwa ku-8%.Ukwengeza, okuqukethwe kwethu kwe-chloride encibilikayo (yamahhala) kungaphansi kuka-5%, futhi okuqukethwe kwethu kwe-sulfate kufinyelela ku-0.2%.
A: Ibhodi le-MgOAmaphaneli e-MgO enziwe ngamaminerali emvelo, i-Magnesium oxide, i-Chloride, ne-Sulphate, eyaziwa nangokuthi usawoti we-Epsom, kanye nothuli lwezinkuni (cellulose), i-perlite noma i-vermiculite, kanye ne-glass fiber mesh.Awekho ama-organic compounds aguquguqukayo noma izithako ezinobuthi ezisetshenziswayo.Isexwayiso: nakuba izinto ezisetshenziswayo zingenabungozi, kunconywa kakhulu ukuthi wonke umuntu agqoke ama-silica/ukhonkolo ophefumula uthuli uma usebenzisa.Ibhodi le-MgOngenxa yothuli oludalwe ngesikhathi sokusika nokusahlabathi.
A: Ibhodi le-MgOingagcinwa kalula endlini ngenxa yomswakama wayo ophezulu nokumelana nomswakama.Kufanele igcinwe endaweni epholile, eyomile, njenganoma iyiphi impahla yokwakha yeshidi.Ukuze uvikele imiphetho namakhona, phatha amabhodi eceleni kwawo.Amabhodi kufanele abekwe phansi phezu kwe-dunnage, izinkuni ezivulekile, i-matting, noma ezinye izinto, hhayi phansi ngokuqondile.Gwema ukuvumelaIbhodi le-MgOkhothama.Ungapakishi ezinye izinto phezu kwakhoIbhodi le-MgO.
A: Ibhodi le-MgOIzakhiwo eziqinile zokunamathela ziyenza ifaneleke ekuqedeni okuhlukahlukene okufana nopende, ukhonkolo, i-stucco yokwenziwa, iphepha lokunamathisela odongeni, itshe, ithayela, nesitini.Ibhodi le-MgOiphinde ibe yinhle kakhulu ukuthi isetshenziswe kuma-Structural Insulated Panels (SIP), Exterior Insulated Finish Systems (EIFS), kanye nezinhlelo zodonga zangaphakathi ezisebenzisa izindwangu.
Uma eqedaIbhodi le-MgOAmaphaneli e-MgO ngemuva kokufakwa, qala nge-primer njengoba amaphaneli ane-alkaline.Sincoma i-primer efanelekile ukhonkolo noma i-masonry.Kunezinhlobo zopende ezidumile ezisabela nge-molecularlyIbhodi le-MgOusimende ukwenza ukunamathela okuphezulu ukumelana ne-UV okuhlala iminyaka.Amajazi e-Acrylic stucco topcoat noma amajazi usimende aguqulwe nge-polymer angasetshenziswa futhi asetshenziswe ngawodwana ebhodini.Ngaphambi kokuqeda yonke iphrojekthi, hlola amajazi aphezulu namapende.Ukuze uhlole ngokunembile ukunamathela kwe-topcoat, sebenzisa upende endaweni encaneIbhodi le-MgO, iyeke futhi yelaphe, bese ushaya u-"X" ngommese obukhali, uyimboze nge-masking tape, cindezela ngokuqinile, bese uyiklebhula ngokushesha.Uma upende luhlala ebhodini, libonisa isibopho esiphumelelayo.
A: Ukukhetha ukujiya kweIbhodi le-MgOkuya ngezidingo zephrojekthi:
- Usilingi: Ophahleni lapho ibhodi lizogqunywa khona libe yigeji yensimbi ekhanyayo noma ukhuni, sebenzisa u-8mm noma ugqinsi.Uma uhlela ukuphikisa isikulufu sekhanda, khetha ibhodi eliwugqinsi.Ngophahla oluphansi usebenzisa amaphaneli e-MgO, amabhodi angu-2mm noma angu-6mm afanelekile.
- Izindonga: Ezindongeni eziningi, ubukhulu bebhodi obungu-10mm kuya ku-12mm buvamile.Ezindongeni ezidinga ukumelana nomlilo okuphakeme kanye nokumelana nomthelela, sebenzisa amabhodi awugqinsi angu-15mm kuya ku-20mm.
- Fi-loor decking ngokuvamile isebenzisa amabhodi awugqinsi ngo-18mm.
- Amabhodi amancane angasetshenziswa uma udonga lusekelwa ngokuqhubekayo usimende noma ukufakwa okuqinile.Lokhu kubalulekile uma isisindo siyinkinga.Isibonelo, ezindlini eziphathwayo, amabhodi angu-6mm asetshenziswe njengesembozo sodonga esisekelwa ngokugcwele.
- Kuzinhlelo zokusebenza ezidinga amandla angeziwe, njengasezindaweni zemidlalo, noma lapho kudingeka khona ukunciphisa umsindo, noma ama-bar countertops asekelayo, amabhodi awugqinsi angu-20mm ayanconywa.
A: UkubophelaIbhodi le-MgOamaphaneli, sebenzisa izinto zokubopha ezimelana nokugqwala futhi wengeze ukwesekwa okwengeziwe ngokusebenzisa ijazi lokuvimbela le-epoxy, i-ceramic, noma ingcina efanayo.Izikulufu ze-drywall zifanelekileIbhodi le-MgOkufanele ibe nensimbi engagqwali noma i-phosphoric coating ukuze ihambisane kangcono.Ukuze kube lula ukufaka, khetha izikulufo ezinamakhanda azibalayo.Uma usebenzisa isibhamu sezinzipho, khetha izinzipho noma izikhonkwane ezifanele zokhuni kanye ne-light gauge steel frameming.UkuqedaIbhodi le-MgOamajoyinti, noma iyiphi inhlanganisela yekhwalithi ephezulu ingasetshenziswa.Hlola ukuhambisana neIbhodi le-MgOngokuthintana nomkhiqizi womkhiqizo.Sebenzisa izigcwalisi zikasimende ezigaywe kahle kagesi, njenge-RapidSet One Pass, ukuze udale amajoyinti okuqinisa izimboni.I-urethanes nayo inamathela kahleIbhodi le-MgOamaphaneli.Uma kukhethwa itheyiphu nodaka, khetha itheyiphu ye-fiberglass ezinamathelayo kanye nodaka noma ukhonkolo olufanele izindawo ezinomswakama.Udaka oluningi olulula oluxutshwe ngaphambili alubekezeleli umswakama kahle, kodwaIbhodi le-MgOAmaphaneli e-MgO angakwazi ukumunca umswakama othile futhi ekugcineni azolingana nesakhiwo esizungezile.
A: Ukuminyana kweIbhodi le-MgOcishe u-1.1igremu ku-cubic centimeter ngayinye, okusho ukuthi ngaphezudlwana kuka-2.3amaphawundi ngonyawo lwesikwele ngamabhodi angu-12mm (1/2 intshi).Ngokuvamile asindayo kunamabhodi e-gypsum kodwa alula kunamabhodi osimende ajwayelekile.
A: Ukuze uthole imiphumela emihle yokusika, sebenzisa isaha eliyindilinga elincane le-carbide noma isaha sokushayela izikelemu.Imiphetho ingahanjiswa kusetshenziswa i-carbide tooling.Uma kuwumsebenzi wokwakha omkhulu, cabanga ukusebenzisa ibhithi ledayimane.Ibhodi le-MgOamaphaneli angaphinda afakwe amaphuzu nge-razor blade futhi ahlwithwe ohlangothini olubushelelezi, nakuba le ndlela ingase idinge ukuqedwa okwengeziwe njengoba inganikezi njengokuhlanzekile konqenqemeni.Ukuze uvimbele ukuqhekeka okuncane emaphethelweni anqunyiwe, kunconywa ukuthi unamathisele wonke amakhona.
A: Ibhodi le-MgOzilungele ukusetshenziswa njenge-subfloor.Ayatholakala futhi ngogqinsi olufanele namandla ukuze asetshenziswe njenge-sheathing yesakhiwo.Ibanga elifanele lebhodi lephrojekthi yakho lincike ezicini ezifana nokwakheka kwephansi, ubude be-joist, isikhala, kanye nokucatshangelwa komthwalo okufile nokuphilayo.
