Pehea ka ikaika o ka papa MgO?

ʻO ka papa MgO (magnesium oxide board) he mea hana maʻalahi a lōʻihi.He mea maikaʻi loa kona ikaika i ka hoʻohālikelike ʻia me nā mea kūkulu hale ʻē aʻe.E noʻonoʻo kākou i nā mea e kōkua ai i ka ikaika o ka papa MgO a me kāna hana ma nā noi like ʻole.

Hoʻohui a me ka hoʻonohonoho

Hoʻokumu ʻia ka papa MgO me ka magnesium oxide (MgO), magnesium sulfate, a me nā mea hoʻoikaika ʻē aʻe e like me ka fiberglass mesh.Hoʻopili kēia hui ʻana i kahi mea ikaika akā māmā hoʻi me ka paʻa maikaʻi.ʻO ka hoʻoikaika ʻana i nā mea e like me ka fiberglass e hāʻawi i ka ikaika tensile hou aʻe, e hoʻemi iki ka papa MgO i ka haki ʻana a me ka haki ʻana ma lalo o ke kaumaha.

Ka ikaika hoʻopili

He hōʻailona koʻikoʻi ka ikaika compressive o ka hiki ke kū i nā ukana kaumaha me ka ʻole deformation.ʻO ka papa MgO maʻamau ka ikaika compressive ma kahi o 15-20 MPa (megapascals), i hoʻohālikelike ʻia me kekahi mau ʻano o ke kaʻa.ʻO kēia ikaika compressive kiʻekiʻe e hana ai i ka papa MgO kūpono no nā noi lawe ukana e like me ka papahele a me nā paneli kūkulu.

Ikaika Flexural

ʻO ka ikaika flexural, a i ʻole ka hiki ke pale aku i ka piko, ʻo ia kekahi ana koʻikoʻi o ka lōʻihi o kahi mea.Hōʻike ka papa MgO i ka ikaika flexural maikaʻi loa, maʻamau mai ka 10-15 MPa.ʻO ia ke ʻano hiki iā ia ke pale aku i nā puʻupuʻu koʻikoʻi me ka ʻole o ka haki ʻana, i mea kūpono no ka hoʻohana ʻana i nā paia, nā kaupaku, a me nā ʻāpana kahi e pono ai ka maʻalahi a me ke kūpaʻa.

Kū'ē i ka hopena

ʻO ka papa MgO ka hopena kiʻekiʻe, ʻo ia hoʻi, hiki iā ia ke komo a hoʻopau i ka ikehu mai ka paʻi ʻana a i ʻole ka hui ʻana me ka loaʻa ʻole o ka pōʻino nui.He koho maikaʻi loa ia no nā wahi kaʻa nui a me nā kaiapuni kahi i maʻa mau ai ka lole a me ka waimaka, e like me nā kula, nā halemai, a me nā hale kalepa.

Hoʻohālikelike me nā mea ʻē aʻe

Ke hoʻohālikelike ʻia me nā mea hana hale maʻamau e like me nā papa gypsum, nā papa sima fiber, a me ka lāʻau, puka pinepine ka papa MgO ma luna ma ke ʻano o ka ikaika a me ka lōʻihi.ʻo kahi laʻana:

Papa Gypsum:ʻOiai hoʻohana nui ʻia ka papa gypsum no nā paia o loko a me nā kaupaku, ʻaʻole ikaika a paʻa paha e like me ka papa MgO.ʻOi aku ka maʻalahi o ka papa Gypsum i ka pōʻino o ka makū a he haʻahaʻa haʻahaʻa ka hopena.

Papa Sima Fiber:ʻOi aku ka ikaika a me ka lōʻihi o ka papa fiber sima akā ʻoi aku ke kaumaha a ʻoi aku ka palupalu ma mua o ka papa MgO.Hāʻawi ka papa MgO i kahi kaulike maikaʻi aʻe o ka ikaika a me ke kaumaha, e maʻalahi ai ka lawelawe a hoʻokomo.

Plywood:ʻO ka Plywood kahi mea maʻalahi me nā waiwai ikaika maikaʻi akā hiki ke maʻalahi i ka maʻemaʻe a me ke ahi.Hāʻawi ka papa MgO i ke kūpaʻa kiʻekiʻe i nā mea ʻelua, me ka ikaika hoʻohālikelike like.

Ka hopena

ʻO ka papa MgO ka ikaika a me ka versatility, kūpono ia no nā ʻano hana kūkulu.ʻO kona ikaika compressive a me ka flexural kiʻekiʻe, ke kūpaʻa ʻana i ka hopena, a me ka lōʻihi ma lalo o nā kūlana kaiapuni e lilo ia i koho maikaʻi loa no nā papahana hale a me nā ʻoihana.Ke hoʻomau nei ka koi ʻana i nā mea kūkulu hale paʻa a paʻa, ua mākaukau ka papa MgO e pāʻani i kahi hana koʻikoʻi i ka wā e hiki mai ana o ke kūkulu ʻana.
