Chokhuthala cha mafakitale ndi chinthu choyeretsedwa kwambiri komanso chosinthidwa. Chikhoza kusintha magwiridwe antchito a kukana kutentha, kukana kukalamba, kusunga kutentha, kuletsa ukalamba ndi zochita zina zamankhwala za chinthucho, ndipo chili ndi mphamvu yabwino kwambiri yokhuthala komanso kukhazikika. Kuphatikiza apo, chilinso ndi kusalala kwabwino kwa kufalikira komanso ntchito zosiyanasiyana.

Chokhuthala cha mafakitale chimagwiritsidwa ntchito makamaka ngati chosungira madzi, chokhuthala, chokhazikika komanso chowonjezera pakuphimba zomangamanga, putty yomanga, bolodi la simenti lotulutsa thovu, matope otenthetsera kutentha akunja ndi mitundu yosiyanasiyana ya zokutira zotsutsana ndi ming'alu komanso zosalowa madzi. Pangani chophimbacho kukhala chowala komanso chofewa, sinthani mphamvu yomanga ndikuwonjezera mphamvu yolumikizirana. Chepetsani kuchuluka kwa ufa wa rabara, simenti, calcium ya laimu, ufa wa gypsum ndi zomangira zina zosapangidwa, ndikuchepetsa ndalama zopangira.

Kugwiritsa ntchito zothina zamakampani zomwe zikulangizidwa:

Musanagwiritse ntchito chophikira cha mafakitale, konzani chidebe, ikani madzi oyenera, kenako ikani chophikira choyenera (0.2%-1.0% ya fomula yonse), ndipo pitirizani kusakaniza kwa mphindi pafupifupi zisanu. Panthawiyi, ngati pali kufunika kwa pH, mutha kuwonjezera madzi otsala ndi sulfure ndikusakaniza kwa mphindi zina zisanu kuti mufike pamlingo winawake. Mukagwiritsa ntchito zophikira, chinthu choyamba chomwe muyenera kulabadira ndi nyengo. Mlingo wa chilimwe ndi nyengo yozizira ndi wosiyana, ndipo kusiyana pakati pa nyengo ziwirizi ndi kotala limodzi. Nthawi yomweyo, onjezerani madzi amchere ndipo siyani kusakaniza, kuti kuwonekera kukhale kwakukulu.

Chenjezo pakugwiritsa ntchito chophikira cha mafakitale:

Choyamba, ziyenera kudziwika kuti zothina zamakampani zimakhala ndi mankhwala a polymer ophiphiritsa, kotero mukugwiritsa ntchito, ndikofunikira kusankha chothinacho chomwe chimagwira ntchito moyenera malinga ndi zofunikira pakugwiritsa ntchito. Nthawi yomweyo, chothina chabwino chamakampani chimakhala ndi mphamvu ya gel, kotero chimakhala ndi mphamvu yogwirizanitsa. Kenako tiyenera kulabadira ubale wapafupi pakati pa kuchuluka ndi kukhazikika kwa chothina chamakampani. Pamene kukhazikika kuli kochepa, kukhuthala kumakhala kochepa mwachilengedwe, chifukwa chake tiyenera kuwongolera mlingo tikasakaniza.

Pomaliza, ngati chokhuthala cha mafakitale chiyikidwa m'madzi, mphamvu yake yosungunulira imakhala yotsika kwambiri, ndipo zimatenga nthawi yayitali kuti chisakanizike bwino. Nthawi zina pamakhala zinthu zosafanana. Pofuna kupewa zinthu zoipazi, choyamba konzani ziwiya zomwe zatchulidwa pamwambapa, sakanizani ndikuziyika motsatizana, kenako muzisakaniza motsatizana.
