Khwatsi mchenga: kukula ndi kupanga

Silika mchenga ndi zinthu zomwe ali ndi chiyambi zachilengedwe ndi makhalidwe osiyana monga mankhwala inertness, kukana kuti kudzitsitsa, durability ndi luso sorbing. Nthawi zambiri izo ntchito kusefera wa mafuta ndi madzi, kwa kupanga yomanga ndi zipangizo kuwamaliza, komanso kulenga m'madamu. Tsopano chilichonse.

kusefera mphamvu

Khwatsi mchenga fyuluta ntchito zambiri kuposa zina lachibadwa. chakuti porosity ake poyerekeza ochiritsira wophwanyidwa mchenga ndi wamkulu kwambiri. Zimenezi, amazipatsa izo mkulu dothi likhale mphamvu ndi sorption mphamvu, kupanga madzi kuoneka ngakhale zinthu monga manganese ndi kusungunuka chitsulo. Pachifukwa ichi, khwatsi mchenga kwa dziwe losambira, nyanja yokumba kapena dziwe, kapena kani, kachitidwe kawo kusefera, ntchito pafupifupi nthawi zonse. Analimbikitsa kachigawo mu milandu ali mu osiyanasiyana millimeters kuchokera 0.4 kuti 6,0.

Ntchito yomanga

Ponseponse ntchito mchenga khwatsi m'dera zomangamanga, makamaka polenga polyurethane ndi epoxy yazokonza pansi. Mu nkhani imeneyi, ndi nusu coarse. Ntchito nkhaniyi kupanga plasters ndi nyumba kasakaniza ndi chifukwa mkulu mankhwala ake kukana, makina kukana kuti onongani ndi kumva kuwawa, komanso bata mtundu. Zindapusa ali chiliri sandblasting ndondomeko galasi konkire ndi zitsulo. chuma ntchito kupanga mwala yokumba.

Jobs ena

Onse ntchito pamwamba pa mchenga silika si. Nthawi ntchito yomanga machitidwe ngalande, greenhouses, madzi bwino kuboola, monga kudyetsa kwa nkhuku, komanso filler kwa insulators magetsi ndi zinthu madzi. M'zaka zaposachedwapa, mtundu uwu wa mchenga angapezeke mu Aquarium ndi malo kulengedwa.

kupanga

Kukhala zofala zachilengedwe chuma, khwatsi mchenga wa miyala mu Zosefera, zipangizo kumanga kapena kuchuluka zina za ntchito si mwachindunji kugunda. Izi zikhoza makamaka amati ndi nuance kuti m'pofunika kusankha nusu oyenera kuthetsa ntchito zosiyanasiyana. Komanso, mchenga zambiri ali wambirimbiri zosafunika zosiyanasiyana, mogwirizana ndi zomwe chuma ayenera chisanadze mankhwala, zomwe ndi ndondomeko m'malo ovuta.

Features ya ntchito

Maonekedwe a wokonzeka kugwiritsa ntchito khwatsi mchenga patsogolo ntchito zosiyanasiyana, kuphatikizapo zipangizo kuyeretsa ku zodetsa, kuyanika, fractionation, mlingo ndi ma CD. Pankhaniyi, Mulimonsemo, munthu sayenera kuchepetsa kufunika kachigawo wa nkhaniyi, chifukwa ena mafakitale (mwachitsanzo, panthawi kupanga galasi), izo ndi mbali yaikulu. muyezo china chofunika, amene amakhala ndi mchenga khwatsi, ndi kusowa kwa mankhwala anachita. Zimenezi zikugwira koposa zonse, kumanga, chifukwa pambuyo solidification simenti matope kapena konkire kumachitika zotsatira osafunika.
