'O ke kūkulu hale Gypsum - mea'ike'ia

Loa pinepine, ma lalo o nā pau ai i ua hana ka hoʻohana 'ana i kekahi mea e like me gypsum puna. 'O nā kānaka mamao loa mai ka hana hou a me ka ho'olālā e'ike i kēia inoa. No nā kenekulia he nui, he mea ma'alahi ia no ka hana hou a me ka ho'oponopono'ana i nā wahi.

'O ke kumu kū'ai'ole o ka hana kūkulu honua'a'ole e ho'oka'awale i waena o nā pāpaku a me nā paia kahiko. He papa maika'i kona, a'a'ole'o ia e pihi. Hana'ia ka hana me ka'ōpiki me ka hu'i'ana me ka wai. Me ke kūlike kūpono, ua ho'opiha pono kēia mea i ka hana i nā hana kūpono a lilo i nā'ano li'ili'i.

Puna i ka porous 'ole, no laila, ua pau surfaces ia i keia mea, pono hiki o Komo' o ia nä hawewe kani, hiki kaulike kani'īpale o ka lumi. 'O ka'ele'ele ke'oke'o o kēia mau mea e hiki ai ke ho'ohana me ka ho'opili'ole'ana i nā wahi e pono ai ke ke'oke'o maika'i o nā kapa komo.

Pehea e loa'a ai kēia mea hale? Natural gypsum, me he mea pōaka 'ole, ua malamaia lakou nei, ma kiʻekiʻe mahana. Ma kēia'ano, he pohō o ¾ o ka wai i loko o ia mea, a ho'ololi'ia ka mineral i loko o kahi hemihyhy, i ka manawa i hui pū'ia me ka wai e hana hou i ke'ano o kekahi pōhaku maoli. No ka mea'a'ole i'oi aku ka nui o ka 1% o nā mea lā'au'ē a'e i nā mea kūlohelohe i ka hana'ana i ka'ōpū, mahalo'ia e nā kānaka a me nā holoholona. He mea loiloi kēia mea hale, no laila he mea ko'iko'i ka mālama'ana i kahi wahi mai ke ahi. Ma waho a'e o nā mea a pau i luna, hiki iā ia ke ho'oulu i ka wai ma luna o ka lumi i ka wā e ala mai ai a hā'awi i ka wai'u i ka ho'oha'aha'a'ia o kona ki'eki'e.

Hā'awi mai'o Gypsum i nā'ano'ano like'ole. Common? Ieoaeunoai kumuhana i hoʻohana no ka manufacturing gypsum pōhaku puna a me nā huahana gypsum, puna papa, Panel a me ka paku papa, gypsum-Lime puna pāʻoihana. Ho'okumu'ia ke'ano o nā mea e hana'ia ai ka hana ma'alahi a me ka hana'ana. Mai ia mea e hana i nā mea'ala a me nā mea nani'ē a'e no nā mea āpau a me nā pae. Kūkulu'ia ka hale Kūkākūkā ma ka manawa o ka pa'akikī: 2-15 mau minuke - ho'onohonoho wikiwiki; 6-30 mau minuke - e hopu mau ana; He 20 mau minuke - e hopu malū.

'O ka ikaika o kēia mea i ho'oholo'ia e kona mau mākia, a he like'ole ia ma ka palena o kona ikaika pa'a (G-2, 3, 4, 5, 6, 7, 15, 10, 19, 16, 22, 25). Ke'ike'ia'o Gypsum grade G-10, 16, 15 he ho'ohui. 'O nā mea like'ole he mea noa wale nō ia mai nā mea'ino a maika'i loa.

Ke hana me kēia mea, e ho'omana'o i ka wikiwiki o ka wikiwiki, no laila,'a'ole e ho'omākaukau koke i ka nui o ka'āpana'ōpala. 'O ka nui o ka wai e makemake'ia e hana i ka hui'ana o nā'ano ma'amau he 50-80% (no ka hana hana) a me 35-45% no ka hana'ana o nā huahana. Hiki i nā wai o ka nui ke waiho i loko o nā pores o ka mea pa'akikī, a ma hope iho ua ho'opili'ia. 'O ka hopena,'o ka porosity o ka hale hale e pili ana he 50-60%. He mea nui e ho'omana'o i ka ho'oemi'ana o ka wai i mea e ho'opau ai i ka pōhaku, ka denser ka huahana i ho'opau'ia ai'ole ka uhi'ana a me ka ikaika o ka nui. 'O ka pi'i a hā'ule'ole paha o ka mahana ka mea maika'i'ole i ka ikaika o ka mea i ho'opa'a'ia. E hoomahuahua i ka ikaika o ka gypsum puna ua i kekahi manawa i hoʻohuiʻia ia ma kahi o 5% slaked Lime.

No ka ho'ohana'ana i nā kumu no ke olakino, ua hana'ia ka inoa o ka polymer gypsum, a hiki ke ma'alahi i ka kino'eha o ka mea ma'i ma kahi kaula. Ho'opiha maika'i'o ia i nā'āpana a loa'a iā ia ka ho'onui i ka ho'opili'ana. Ua ho'onui'ia ka porosity o kēia mea, no laila e ho'omaha mau ana ka'ili o ke kanaka i mea e ho'omaha ai. I kekahi manawa ua ho'okū'ia kēlā mau kāpili i hiki i nā ma'i ke hana i kekahi mau hana. 'A'ole pilikia kēia'ili i nā hana lapa'au a me ka nanea X-ray.
