Musanayambe kujambula, kumanga khoma kapena kuphulika, pamakhala mwachidwi kufunika kokhala pansi. Pano, anthu ali ndi zosankha ziwiri: kugwiritsa ntchito gypsum bolodi kapena kupita ku malo ena achikhalidwe. Njira yoyamba ikukwera mofulumira kwambiri komanso kupindula kwakukulu pa nkhani yolenga zitsulo, zitsulo ndizitsulo zambiri . Koma pa nthawi yomweyi, mawindo otsekemera amachepetsa kwambiri mpukutu wa chipindacho, amaopa mantha ndipo amakhala ndi moyo wautali. Kodi ndinganene chiyani za pulasitala. Njira iyi, ngakhale zimatengera nthawi yambiri kukhazikitsa, koma izi zidzatumikira kwamuyaya.
Masiku ano mitundu yambiri ya pulasitala imaperekedwa, koma malo otsika mtengo kwambiri omwe amapezeka amakhala amchere. Ndiwophatikizana ndi ufa, chomwe chimamanga ndi simenti. Mitengo yowimidwa imagwiritsidwa ntchito kumadera onse okonza, chifukwa mtengo wawo mtengo ndi 2-3 nthawi zochepa kusiyana ndi zipangizo zofanana.
Sakani mankhwala osakaniza
Malingana ndi kukula kwa pulasitala ndi zigawo zikuluzikulu za osakanizazi zidagawidwa mu mitundu iwiri:
- Msuzi wa mchenga wa pulasitala. Chofunika kwambiri ndi mchenga. Zokonzedwa kuti zikhale zong'onong'ono za makoma apakati ndi maonekedwe, kuchoka kwa pamwamba kufika ku zero. Osati malo abwino okhala ndi chinyezi chakuda. Zakudya za simenti pano sizing'ono, chiwerengero cha 1: 5 chikusungidwa, ndiko kuti, chiŵerengero chomwecho chofanana ndi zomangamanga. Kusiyana kokha ndiko kusinthika kwa maonekedwe akuyenera kukhala kowala.
- Chomera chomera chaimu. Chigawo chachikulu ndi laimu. Kuchuluka kwake kwa kuimitsidwa ndi motere: makilogalamu 20 a laimu, 280 makilogalamu a mchenga, 50 l madzi, 25 makilogalamu a simenti. Njirayi imagwiritsidwa ntchito m'chipinda chokhala ndi chinyezi chachikulu (galasi, khitchini, malo osungira, zipinda zamkati), monga pulasitala sizimataya katundu wake ndipo sizikutha. Kuyika pulasitala ndi kusakaniza kwa laimu ndi koyenera kumaliza chimanga, miyendo ndi malo ena pomwe mchenga wa pulasitiki umakhala wotsika pakhoma.
Mitundu iwiri ya pulasitala ndi yomwe imagwiritsidwa ntchito kwambiri ndi zokongoletsera zapakhomo. Mafananidwe ena (gypsum, acrylic, silicone plaster) ali ndi mtengo wapamwamba ndipo samapereka zizindikiro zoyenera zomatira. Iwo ali oyenerera kwambiri kukongoletsa ndi kumaliza ntchito.
Kuyika makoma ndi simenti yamchere: malamulo
Zomwe zimagwiritsidwa ntchito pa simenti zili ndi makhalidwe ake enieni, koma zimangowonekera ngati zikhalidwe za ntchito zikuwonetsedwa. Choncho, mchenga wosakaniza uyenera kukhala ndi tinthu tating'onong'onong'onong'o ting'onoang'ono, mwinamwake pamwamba pake padzakhala kusintha kwasintha, ndipo ngati madzi ochulukirapo akuwonjezeredwa ku njirayi, ubwino wa shrinkage ndi mlingo womatira pamtambo ukuchepa. Akatswiri amadziŵa zinthu zingapo zomwe zimakhudza ubwino wa kupaka:
- Pa nyengo yozizira ndi nyengo yamvula, sikuvomerezeka kugwira ntchito ndi kusakaniza;
- Muzojambula zimalimbikitsidwa kuwonjezera 10 magalamu a shampo kwa malita 10 a kusakaniza (kusweka kudzachotsedwa);
- Peŵani kusintha kwa makulidwe a zigawo pa khoma limodzi;
- Kuwombera kachiwiri kuyenera kuchitidwa mu chiwerengero chomwecho monga choyamba, mwinamwake ziwalo zidzawonekera ndipo ming'alu idzawoneka;
- Sitima yamatabwa yokonzeka iyenera kukhalapo, kuti mpweya wonse wochulukira utuluke;
- Chifukwa cha simenti wochuluka kwambiri, malo osanjikiza angapereke ming'alu chifukwa cha kuponyedwa.
Akatswiri amanena kuti m'mabwalo akulu ndi ofunika kugwiritsa ntchito makina opaka. Adzapereka mapepala onse pakhoma poyerekezera ndi kuonjezera zokolola za ntchitoyi maulendo asanu. Makamaka ayenera kulipidwa ku pulasitala yamenti ku bafa. Kumbukirani kuti ntchito yowonjezeretsa kuyika matayala ingayambike patatha masabata atatu mutatha kugwiritsa ntchito chisakanizo. Zidzatenga nthawi yochuluka kuti yakhazikike.
