Na Waiwai a me na Waiwai o na Papa MgO

Hōʻoiaʻiʻo Puʻupuʻu: Hoʻopili ʻia i kēlā me kēia Kaiapuni Wai

ʻO nā papa MgO no nā mea gel coagulable ea, ʻo ia ka mea maʻamau ka maikaʻi ʻole o ka wai.Eia naʻe, ma o kā mākou hoʻololi ʻenehana ʻōnaehana, hōʻike nā papa MgO i ke kūpaʻa wai maikaʻi loa.Ma hope o 180 mau lā o ka luʻu ʻana, ʻoi aku ko lākou ʻoluʻolu ma luna o 0.90, me kahi pae paʻa ma waena o 0.95 a me 0.99 i ka wā o nā hoʻāʻo kaiapuni mau.ʻO kā lākou solubility i ka wai ma kahi o 0.03g/100g wai (gypsum he 0.2g/100g wai; sulfoaluminate cement he 0.029g/100g wai; Portland cement he 0.084g/100g wai).ʻOi aku ka maikaʻi o ka pale wai o nā papa MgO ma mua o ka gypsum, a ua like lākou me Portland cement a me sulfoaluminate cement, e hoʻokō pono ana i nā koi no ka hoʻohana ʻana i nā wahi pulu.

Nā hiʻohiʻona noiʻi

Nā lumi ʻauʻau a me nā lumi kuke:Hana maikaʻi loa nā papa MgO i nā wahi haʻahaʻa kiʻekiʻe, no ka hoʻohana ʻana i nā lumi lumi a me nā lumi kuke.Hōʻike pinepine ʻia kēia mau wahi i ka wai a me ka mahu, a ʻo ke kūpaʻa wai kiʻekiʻe o nā papa MgO e hōʻoia i ka lōʻihi a me ka paʻa i kēia mau hoʻonohonoho.

Na Halelalo a me na Waihona: Hoʻopilikia pinepine ʻia nā haʻahaʻa haʻahaʻa a me nā waihona i ka maʻu a me ka pulu ma muli o ko lākou kokoke i ka lepo.ʻO nā waiwai wai ʻole o nā papa MgO e lilo lākou i koho maikaʻi loa no kēia mau wahi, e pale ana i ka komo ʻana o ka wai a me ka mālama pono ʻana i ke kūkulu ʻana.

Na Pa waho a me na hale: ʻO nā hiʻohiʻona wai ʻole o nā papa MgO e kūpono iā lākou no nā paia o waho a me nā hale, e pale ana i ka ua a me ka wai, a me ka hōʻoia ʻana i ka palekana o nā hale.

Ka Aakika & Alkali Kū'ē o nā Papa MgO

ʻAkika a me ka alkali pale:Pili i ka High Corrosive Environment

Ma hope o ka hoʻonāʻiaʻana i ka 31% magnesium chloride acid solution no nā lā 180, piʻi ka ikaika compressive o nā papa MgO mai 80MPa a i 96MPa, me ka piʻi ikaika o 18%, e hopena i ka coefficient kū'ē corrosion o 1.19.I ka hoʻohālikelike ʻana, ʻo ka coefficient kūʻē corrosion o ka sima Portland maʻamau ma kahi o 0.6 wale nō.ʻOi aku ka kiʻekiʻe o ka pale ʻana o nā papa MgO ma mua o nā huahana sima maʻamau, kūpono loa ia no ka hoʻohana ʻana i ka paʻakai kiʻekiʻe a me nā wahi corrosive, e hāʻawi ana i ka pale corrosion maikaʻi.

Nā hiʻohiʻona noiʻi

Nā Hale Kai:Hana maikaʻi nā papa MgO i nā kaiapuni paʻakai kiʻekiʻe, no laila kūpono lākou no nā hale kahakai.Hiki i ka paʻakai ke ʻino loa i nā mea kūkulu hale maʻamau, akā ʻo ke kūpaʻa paʻakai o nā papa MgO e hōʻoia i ka lōʻihi o ka lōʻihi ma ia mau kaiapuni.

Nā mea kanu Kimia a me nā Laboratories: I loko o kēia mau kaiapuni koʻikoʻi kiʻekiʻe, hāʻawi ka MgO papa 'acid a me ka pale alkali i ka pale maikaʻi loa, me ka hōʻoia ʻana ʻaʻole i hōʻino ʻia nā mea hana e nā mea kemika.

Nā Mea Hana Hana: Ua kūpono nā papa MgO no nā ʻoihana ʻoihana like ʻole, ʻoi aku hoʻi i nā medium corrosive nui, e hāʻawi ana i ka pale hilinaʻi a me ka lōʻihi lōʻihi.

Ka hopena

ʻO ka wai ʻole, ka pale ʻana i ka wai, a me nā waiwai pale a me ka alkali o nā papa MgO he mea nui ia i ka hana hou.Inā ma nā wahi wai a i ʻole nā ​​wahi corrosive kiʻekiʻe, hāʻawi nā papa MgO i ka pale kūʻokoʻa, e hōʻoia ana i ka paʻa a me ka palekana o nā hale.
