Mavitamini a pulasitala si okhawo omwe amagwiritsidwa ntchito pomaliza kukongoletsera, komanso omwe omwe ali ndi cholinga - kuyendetsa pamwamba pa makoma ndi denga mkati mwa malo. Mmodzi mwa iwo ndi pulasitala wokhala ndi pulasitala. Kuti timvetsetse bwino nkhaniyi, tiyeni tione zochitika zina za gypsum plaster .
Zomangamanga zimakhala ndi gypsum plaster
Monga tafotokozera kale, pulasitikiyi imagwiritsidwa ntchito pokhapokha poyerekeza ndi zina, zipangizo zamakono zowonongeka zomwe zimagwiritsidwa ntchito pazochitika zotero (pali zothetsera simenti ndi simenti), zili ndi ubwino wambiri wosatsutsika. Kotero ... pulasitiki ya Gypsum ndi yophweka komanso yabwino kugwiritsa ntchito - atapempha kuti apitirize kuchiritsidwa, pulasitikiyo imangowonongeka ndi lamulo, ndikuyang'ana ma beacons. Yotsatira:
- Kutseka nthawi. Mapira a gypsum amauma mofulumira kusiyana ndi mitsuko ina, koma sagwedezeka ndipo, motero, palibe phokoso lokhazikika pamtambo pambuyo pa kuponyedwa kwa matabwa;
- ndi zotsekemera kwambiri ndipo zimakhala ndi phindu lokwanira (poyerekezera ndi pulasitiki imodzimodziyo);
- Zitha kunenedwa kuti ndizolemera kwambiri, chifukwa zimagwiritsidwa ntchito pa zigawo ziwiri zokha (poyerekezera - pulasitiki yamagetsi iyenera kugwiritsidwa ntchito osachepera m'magawo anayi).
Kodi ndiyenso ndinganene chiyani za mapaipi onse a gypsum? Kuchita kotereku kumapangitsa kuti pulasitikiyi ikhale yosakaniza chifukwa cha zowonjezereka zowonjezera madzi. Zitha kugwiritsidwa ntchito popangira zipinda zodyeramo (zipinda, makilomita), komanso zipinda zomwe zili ndipadera, mwachitsanzo, muzipinda zodyera ndi khitchini.
