Ndi mitundu yanji ya ma siling'i omwe alipo

Kukweza gulayendi gulaye zoluka kuchokera ku zipangizo zopangira ulusi. Ndi zopepuka kwambiri kuposa zingwe zachitsulo zokokerana pamtundu womwewo. Amagawidwa makamaka m'mitundu iwiri: gulayeti lathyathyathya ndi slings osinthasintha. Kusiyana kwa mitundu iwiriyi ndikuti ali ndi mapangidwe osiyanasiyana. Pankhani yogwiritsira ntchito, kulemera kwake kwa lamba lathyathyathya kumakhala kochepa ndipo kusinthasintha kumakhala kwakukulu. Itha kugwiritsidwa ntchito pokweza matani akulu akulu amakampani.

Pamwambapa ndi magulu awiri akulu okha. Mitundu iwiriyi ya zingwe zonyamulira zimatha kugawidwa m'mitundu itatu. Opanga osiyanasiyana ali ndi zizindikiritso zamitundu yosiyanasiyana. Mitundu itatu iyi ndi:

1. Chovala chozungulira: ndiko kuti, lamba lonse ndi dongosolo lotsekedwa

2. Ndi zomangira pawiri: Maso amasokedwa mbali zonse ziwiri za lamba kuti athe kulumikiza mbedza ndi malo ena okweza.

3. Okhala ndi zingwe zamaso ndi zingwe zachikopa: Chikopa chowonjezera cha zingwe chimasokedwa pathupi lamba kuti chisiyanitse ndi mtundu wake.

Ponena za mitundu itatu yomwe ili pamwambayi, yomwe nthawi zambiri imatengera zomwe zachitika komanso kagwiritsidwe ntchito kake, ma slings amtundu wa EB nthawi zambiri amagwiritsa ntchito zingwe ziwiri zamtundu wa EB, ndipo zokhotakhota zimagwiritsa ntchito ma EA kuzungulira ndi EA-A.

Kuwonjezera pa kusiyana kumeneku, mtundu wa lathyathyathya umawonjezeranso gulaye yoyera, yomwe imasiyanitsidwa ndi mtundu kukhala mtundu wina. Mtundu uwu umagwiritsidwa ntchito makamaka m'malo owononga asidi ndi alkali, pomwe mitundu ina imagwiritsidwa ntchito m'malo okhazikika.

Pamwambapa ndi kugawanika kwa mitundu yonse. Mukhoza kusankha malinga ndi malo enieni ndi zosowa. Malingana ndi zochitika zenizeni zogulira ogwiritsa ntchito, anthu ambiri amasankha zoyera zoyera chifukwa ndizotsika mtengo. Komabe, ziyenera kuzindikiridwa kuti zoyera Kukana kwa asidi ndi alkali ndizotsika mtengo, koma mphamvu sizikhala zapamwamba monga mitundu ina, choncho nthawi zina sizingakwaniritse zofunikira za mphamvu zonyamula katundu.
