Mphamvu chitsulo Chalk mphamvu zovekera ngodya zitsulo mtanda mkono

Ntchito ya mkono wodutsa: chitsulo chopindika chokhazikika pamwamba pa mtengo wamagetsi, chokhala ndi mabotolo adothi, chimagwiritsidwa ntchito kuthandizira waya wamagetsi.

Dzanja la mtanda ndi gawo lofunika kwambiri la nsanja. Ntchito yake ndikuyika ma insulators ndi zopangira kuti zithandizire ma conductor ndi mawaya amphezi, ndikuzisunga patali pang'ono potsatira malamulo.

Gulu la mtanda la mkono: likhoza kugawidwa mu: mkono wowongoka; mkono wopingasa pamakona; Kulimbana mkono wopingasa.

Ikhoza kugawidwa mu: mkono wachitsulo; mkono wa mtanda wa porcelain; Synthetic insulated mtanda mkono.

Kugwiritsa ntchito: mkono wozungulira wozungulira: ingoganizirani kunyamula katundu woyima ndi katundu wopingasa wa kondakitala pansi pa kulumikizidwa kwabwinobwino;

Kulimbana kwapang'onopang'ono mkono: kuwonjezera pa kunyamula katundu woyima ndi wopingasa wa woyendetsa, idzakhalanso ndi kusiyana kwapakati pa woyendetsa;

Pakona pamtanda mkono: kuwonjezera pa kunyamula katundu ofukula ndi yopingasa wa kondakitala, adzakhalanso lalikulu unilateral kondakitala mavuto.

Malinga ndi kupsinjika kwa mkono wamtanda, mkono umodzi wodutsa uyenera kutengedwa kuti ukhale ndodo yolumikizira kapena ndodo yapakona pansi pa madigiri 15, pomwe mikono iwiri yopingasa iyenera kutengedwa ngati ndodo yapangodya, ndodo yomangika, ndodo yomaliza ndi ndodo yanthambi yokhala ndi chingwe. ngodya yopitilira madigiri 15. (mikono iwiri yopingasa imagwiritsidwa ntchito pamitengo m'malo ena)

Dzanja la mtanda nthawi zambiri limayikidwa 300mm kuchokera pamwamba pamtengo, mkono wowongoka umayikidwa kumbali yolandila mphamvu, ndipo mkono wamtanda wa mlongoti wapangodya, mtengo wotsiriza ndi mtengo wanthambi udzayikidwa kumbali ya waya.
