• ukuphwera, wosasiya fungo.

dosing

The zosungunulira anawonjezera kuti utoto kapena varnish mu tiziduswa tating'ono ting'ono kuti osalimba anakhumba ndi kukhuthala. Ayipanga osakaniza kotero nthawi zonse oyambitsa. Popeza zosungunulira ali ndi ntchito yapamwamba, pamene tikugwira ntchito ndi izo zizikhala makamaka kusamala kusokoneza m'munsi wosanjikiza ❖ kuyanika.

tipewe ngozi pamene ntchito ndi zosungunulira

Ziyenera kuperekedwa mu zipinda ndi mpweya wabwino, chifukwa mankhwala ndi poizoni (wachinsinsi monga wachitatu kalasi ngozi). Komanso, pamene tikugwira ntchito ndi zizindikiro zosungunulira 646 kugwiritsidwa ntchito ngati PPE monga makina ndi magolovesi. Izo analimbikitsanso ntchito magalasi chitetezo.

Ngati wothandizila anali m'dera la khungu, ayenera kulandira chithandizo ndi madzi (otentha) ndi sopo. Mu nkhani ya kukhudzana ndi Kakhungu mucous diso pambuyo kutsuka ayenera kukaonana ndi dokotala.

Popeza kuti zosungunulira ndi chuma flammable, m'pofunika kusamalira mosamala ndi m'mikhalidwe palibe musalole lotseguka malawi, nsakali ndi kusuta pafupi akasinja ndi reagent lapansi.

Kodi kusunga?

zosungunulira anali kusungidwa mu chotengera mwamphamvu chatsekedwa. Kuwonjezera apo, muli ndi reagent ayenera kutetezedwa ku chinyezi, dzuwa ndi kutentha. Inu sangachoke zipangizo aliyense Kutentha pafupi nthawi yomweyo muli zosungunulira.

The chitsimikizo nthawi yosungirako (monga alimi mudziwe) kuchokera tsiku kupanga miyezi 12, chomwe chimathandiza mabizinesi kugula mankhwala amenewa lalikulu zedi.

Mfundo kutentha pa zomwe zosungunulira amasungidwa, ali mu osiyanasiyana kuchokera opanda 40 kuphatikiza 40 deg.
