Pehea e koho i kekahi refractory pōhaku umu ahi?

Ma ka hana o ke kapuahi mea i hiki ke hoʻohana maʻamau ia i kī pū nā pōhaku lepoʻulaʻula, maʻamau Ana o ka a - 250h120h65 mm o. Ua E i maopopo kihi,ʻaʻohe chipping, malimali kihi a me ka pololei pana pua. I ole ia ka lālau nō e fragile. Ma ka huli ana o ka pōhaku 'ole e e homogeneous,ʻo ia hoʻi, e ma i na mawae, voids a me ka papa.

Ka hao ka mea e hoohehee - papa perezhzhonnogo pōhaku lepo hiki wale ke hoʻohana 'ia no ka mea o ka umu kumu, no ka mea, ua hoopili i ua hoʻopili i ka pāʻoihana. Unburned (ula),ʻimi hoʻopunipuni pohaku, Lime, perforated a me ka puha na pohakulepo lawelawe no ka kau ana o nā umu a me ka nanaina hookae i ole ae.

Refractory pōhakuʻula, i ke kumu kuai o kekahi mau manawa ma luna ma mua o ka ulaula pālolo pohaku ua koi 'ia no ka naʻau o thermal naehana. Ia mea, e hana i kekahi aiiay wahi ua hoʻohana 'refractory, i kapa i ka lua ahi. Manawa a hiki i kēia, i ka wela ua loaʻa i loko o ke kahe 'aʻole i luku aku i ka papa kuhikuhiE paia o ka lua ahi.

kākoʻo pāʻoihana

A refractory umu pōhaku lepo pono e waiho i loko o ka 'ole a me ka noi o ka homogeneous pāʻoihana a makemake ikaika e paʻa lālau a solidify i loko o ka manawa maoli. No ka lulu popilikia stoves i hoomakaukauia hoʻohana lepo pāʻoihana, ke kaumaha ma muli o ka momona ka maʻiʻo o ka lepo me ka hou o ke one i loko o huliāmahi o 1: 1 a 1: 2. Noonoo kupono ke hoomakaukau pāʻoihana, ina e olokaa mai i kekahi mea poepoe, i ka wa maloo paha crack ma ka contour, a me ka wā kiola ai i ka papahele ua i puehu wale aku no. Inā i koe o ke one, oiai poepoe haule ma ke kaʻawale, māwae, haawi alo aku o ka like ana nui o ka lepo i loko o ka pāʻoihana.

I ka waiho ana hanalima? Ieaoa firebrick sila pu hoʻohana papa wiliʻai - he calcareous pāʻoihana manao no ka paa refractory huahana.

Kūkākūkā o masonry

I ka kukulu ana i na, hoʻomaikaʻi hou o thermal naehana refractory pōhaku lepo masonry aie i ka keia mau koi, i hooholo kona waeʻano:

• ʻO kā mākou mānoanoa o ami ma waena o 0.5 a me 1 mm o hoʻopili like ka pakahi aku la ia manao e waiho ana i kekahi waeʻano i.
• Sutures ka nui o 1-2 mm o ma waena o nā pōhaku lepo no i mau waeʻano.
• Hae (vulgaris) wehewehe aku ma ka mānoanoa masonry ami i 3 mm o.
• Loaʻao ka lepo ma waena o nā pōhaku lepo a 3 mm o hoʻopili like i kekahi mea refractory brickwork.

Classes, refractory papa, waeʻano masonry - kēia 'ike a pau pono ia e ka pela mai i loko o ka palapala hana. Ināʻaʻohe mea'ē aʻe, a laila, ua paa i ka mānoanoa o stitches no okoa mall oihana mua ma luna o ka muli o kekahi papa.
