Anthu ambiri, atamva tanthauzo la "pulasitiki youma" aganizirani kusakanikirana kwa simenti, mchenga ndi mitundu yofiira, yomwe imagwiritsidwa ntchito ku khoma lokonzekera. Ndipotu, izi ndizowonongeka nthawi zonse, zomwe mwaziwona nthawi zambiri m'masitolo apadera. Mapepala apamwamba kwambiri akhala ophweka poyika piers, kukweza makoma, zitsulo zosungidwa ndi zofunikira zina.
Phalala lakuda la makoma: khalidwe
Monga tanena kale, pulasitala uwu ndi pepala la pulasitiki. Zomwe zimapangidwanso ndi izi:
- gypsum, yomwe ndi maziko a pulasitiki (93% ya pepala);
- makatoni kapena pepala losavomerezeka lomwe silingalole pepalalo kuti lisinthe;
- wowuma wowonjezera, womwe umagwirizanitsa chirichonse palimodzi;
- zinthu;
- Zida zina zimagwiritsa ntchito matope omwe amateteza moto.
Phindu lalikulu la mapepala amenewa ndizochita zogwiritsira ntchito, monga momwe zilili zoyenera kumaliza ndi mapepala , mapepala , mapepala ndi zipangizo zina zomwe zimayang'aniridwa ndi zizindikiro zowonongeka. Zinthuzi ndizochezeka, zosagwirizana ndi kutupa, zimakhala ndi maonekedwe abwino, zimayambitsa maonekedwe a bowa ndi nkhungu.
Mitundu yokongoletsera
Pakali pano, omanga amagwiritsa ntchito mitundu yambiri ya kumaliza ndi mapulasitiki otere: kukonza gypsum slurry, kusakanikirana simenti ndi pulasitala wouma. Tiyeni tione mwatsatanetsatane mtundu uliwonse wa pulasitala:
- Gypsum kuyimitsidwa. Amagwiritsidwa ntchito kumangirira pepala ku malo achitsulo ndi njerwa. Nthawi zambiri, ntchito yapadera ya gypsum mastic imagwiritsidwa ntchito, yomwe imakonzedwa motere: gawo limodzi la utuchi limaphatikizidwa ndi magawo 4 a gypsum ndi guluu madzi (chidebe cha madzi g glue). Pakadutsa maola angapo mutatha kugwiritsa ntchito, gypsum imadutsa malo amphamvu komanso ndi makapu a gypsum ndizotheka kugwira ntchito.
- Phalala yowuma. Pokonzekera, njira yothetsera 1: 3 imagwiritsidwa ntchito, yomwe ikugwiritsidwa ntchito poyika njerwa. Lamulo lalikulu ndilo kuti osakaniza ayenera kukhala okonzeka kwambiri ndi ovundikira kuti awonongeke mosavuta pamwamba. Ubwino wa ntchito imeneyi ndilo liwiro lapamwamba komanso luso lokonzekera nokha.
Chonde dziwani kuti kukonza chowongolera pamsanganizo ndi kotheka kumangidwe (kumapeto kwa khoma). Pamwamba, timapepala timaphatikizidwa pogwiritsa ntchito misomali / zipsera ku chitsulo chisanayambe.
Kumanga zosakaniza
Ngati tilingalira mapepala kuchokera kumalo osakanikirana, ndiye kuti tikhoza kusiyanitsa ma subspecies ofanana. Motero, pulasitiki yamagetsi amagulitsidwa mu mawonekedwe omwe asanatchulidwe m'mabotolo apadera. Zowonjezerazo zimaphatikizapo simenti, mchenga, zigawo za mchere, zomangira zokha. Yankho lokonzekera pamaziko a chisakanizo ndilokwanira pulasitiki ndipo ali ndi luso lapamwamba la kusungirako madzi. Anagwiritsidwa ntchito pomaliza mapepala ndi malo ogulitsa mafakitale. Imakhala ngati maziko a kugwiritsa ntchito zokutira zokongoletsera.
Mapuloteni a Gypsum amapangidwa ndi gypsum ndi zowonjezera mapulitsi. Kugwiritsa ntchito mankhwalawa kumakhala kochepa kangapo kusiyana ndi mchenga wa simenti. Pogwiritsira ntchito makina pali pulasitala ndi puttying imodzimodzimodzi. Mfundozi zingagwiritsidwe ntchito pa ntchito yobwezeretsa, kupanga zinthu zokongoletsera. Ndipo pomalizira pake, pulasitala wowongoka wouma. Amagwiritsidwa ntchito pamzere womaliza
mtengo ndipo ndilo gawo lomalizira lomaliza makoma.Zopangidwe zimaphatikizapo zopangidwa ndipadera zomwe zimapangitsa kuti nkhopeyi ikhale yodabwitsa, ndikupanga chitsanzo chosazolowereka. Chokongola ichi chimawoneka chokongola ndi choyambirira.
