Hoakaka a me kekahi 'umekaumaha o ka hoʻonui he palolo kekahi

Hoomaka pālolo - bulk hahana maoli nō kēia mea. Anei he Lightweight, porous lei a me nā mōhai fusible palolo, ka haku mele o ke koa environmentally palekana a me ka maluhia no kanaka ola a me ka 'ia.

'īpale ia e hoʻokō, hoomaka lepo nuʻa e e uuku. He hiki ke hoʻokō ma ka hua nui i ka lepo. Kēia ia lŘlŘ ma ka aaioee kaulahao ma ka hola:

1. Ka kūikawā nā mea hoʻonoho fusible lepo ua hoolilo i ka ikaika thermal kŰia. Penei, he kiʻekiʻe porosity o ka mea.

2. Eia, ua heʻe maka porous granules mai ka waho - i kū ai i ka ikaika a me ka manao pono kiʻekiʻe pono e lakou ke ku imua ona, aʻano pākīkē 'ia hoʻopale lei meakino.

Kōmike 'ano o ka hoomaka lepo e pono e kaukaʻi ma ka pololei o ka manufacturing keʻano o ka hanaʻana: he holo mai o nā ana hoʻohālike o ka manufacturing i ka hopena i lawa porosity a me ka tightness, fragility'īpale.

Like kekahi hale mea, hoomaka lepo mai i kekahi lākou o nā 'ano e ae no ka manao o ka mea ma lalo o kūkulu. Mau nā:

• Bulk a me kekahi nuʻa.
• Wai hoʻopale a me ka ona mau.
• Brand ikaika.
• Thermal conductivity.
• Hau e kū'ē'ē mai.

'īpale hoʻokaʻawaleʻia i loko o nā pūʻulu e like me ka nui a me ka pa apŘ o ka hoomaka lepo granul.Fraktsiya pili inverse ke ano - i ka uuku o ka lei, ke kiekie o ka lākiō o ka nuipa a i ka leo:

Aia o kekahi Mea Maluna, a haawi mai GOST 9757-90. E like me ka palapala, pōhaku puna aeie ua maheleia i papa e like me ka mea pa apŘ. ʻO kona mau denoted ma ka palapala M ukali ma ka laulā waiwai o ka mea i kā mākou nuʻa no ka waeʻano: M250 kaupaona 250 kg / ka m ^3, oi ma ka mea ana i M600: M300, M350, M400, M450, M500.

Ka lākiō hana

Bulk nuʻa o ka hoomaka lepo ua inextricably ua hoʻopili i nā nui aʻe - humidity a me ka wela conductivity. Kēia hiʻona ua mau ia i loko o ka wā no ke kohoʻana i kekahi mea no ka thermal'īpale o ka palaoa, nā kaupaku a me ka pā.

Ike i ka maʻamau cia o ka bulk nuʻa a me ka hapa iki o ka hoomaka lepo, ua hiki ke hoʻoholo kona ona mau maʻiʻo. Inā ka mea, uaʻoi kona kiʻekiʻe ma mua o Ke aeia'ku nei ia, i ka porous granules i ia e maloo mua noae i kūkulu. GOST 9757-90 "iliili, pepe iho la ka pohaku a me ke oneʻimi hoʻopunipuni porous" regulates i oi aku mamua o 2% ka liki ole ona mau. Alaila, i ka wa he pāʻumi keramzita lawe i loko no o ka pauna ana o ka wai i loko o laila, a laila ka mea, ua unuhi.

Ka lākiō o thermal conductivity i ka pa apŘ conventionally, akā nō ia lŘlŘ. E like me ua ikeia mai ka ke kālaikūlohea papa maʻamau, me ka haahaa o ka waiwai o ka nuipa a-i-ka leo hiʻohiʻona, i ka mua o ka mea e lawelawe ai wela. Keia rula i pili i ka wehe i hoʻonui i ka lepo. Ke denser ia mea, i ka ÿino i hoopaa mai ai i wela. I ka wa ana e like me ka mea pono e pono e huli i ke koi 'ia waiwai o ka ahu iho ai i ka hana, aole ia i pa ahau, a me ke ea olu ua i mākaʻi.
