Njira zosintha zovuta pambuyo ponyamula

Mukakhazikitsa, musamatonze mwachindunji nkhope yakumapeto kwa nkhope ndi osakhazikika. Press Clock, malaya kapena zida zina zokhazikitsa ziyenera kugwiritsidwa ntchito popanga mphamvu yovala yunifolomu. Osayikira ndi thupi logwedeza. Ngati malo ophatikizidwa ndi mafuta, zimapangitsa kukhazikitsa kosalala. Ngati kulowerera koyenera ndi kwakukulu, kunyamula kwa 80 ~ 90 ℃ m'madzi a mchere ndikuyika mwachangu, kuwongolera kutentha kwamphamvu sikupitilira 100 ℃. Mukakumana ndi mavuto mu shagambly, tikulimbikitsidwa kuti mugwiritse ntchito chida chosagawanika kuti mutuluke mozama pomwe ndikuthira mafuta otentha mumpheunga wamkati, kutentha kumapangitsa kuti mphete yamkati ikhale yokulirapo, kotero kuti ndikosavuta kugwa.

Sikuti mapepala onse amafuna chilolezo chocheperako, muyenera kusankha chilolezo choyenera malinga ndi momwe zinthu zilili. Ku National Standard 4604-93, chilolezo cham'madzi chofuula chimagawika m'magulu asanu: Gulu 2, Gulu 0, Gulu la 3 ndi Gulu la 1. Gulu loyambira loyambirira ndi loyenera pakugwiritsa ntchito bwino ntchito, kutentha wamba komanso kusokonezedwa wamba. Chitsimikizo chachikulu cha radio ayenera kusankhidwa kuti zisagwire ntchito zapadera zomwe zimatentha kwambiri, kuthamanga kwambiri, phokoso lotsika komanso kukangana pang'ono. Chitsimikizo chaching'ono cha radical chimayenera kusankhidwa kuti chikhale chowongolera spindle ndi chida chamakina chopindika; Chida chogwirira ntchito chitha kusungidwa chifukwa cha zokulirapo. Kuphatikiza apo, palibe chilolezo cholekanitsidwa; Pomaliza, chilolezo chogwirira ntchito chitatu chikayika chizikhala chocheperako kuposa chitsimikizo choyambirira chisanakhazikike, chifukwa chonyamula katundu chimakhala chokhazikika ponyamula zokwanira ndi katundu.

Poona vuto lakusindikiza lazovala ndi kusindikizidwa, pali njira ziwiri zochitikira mu njira yosinthira.

1. Dongosolo lokhala ndi chithunzi chophimba kusinthidwa kumbali zonse za kubereka, ndipo kukhazikitsa kapangidwe kazomwe kubereka kumasinthidwa ndi zida. Kulumikizana mwachindunji ndi zonyamula sikufunikira, ndipo zonyamula ndi chitsimikizo kuchokera kunja kwa kubereka. Mphamvu zachinsinsi za kapangidwe kameneka ndizokwezeka kuposa momwe zimapangidwira kugulitsidwa mwa kubereka, zomwe zimalepheretsa njira ya galelar ndipo zimatsimikizira ukhondo wa momwe akumvera. Izi zimathandiza malo osungirako kutentha osakhala ndi kuwonongeka kwa kutopa kwa otsutsa.

2. Ngakhale njira yosindikizira yakunja ili ndi vuto lalikulu, njira yotentha imatsekedwanso, kotero zigawo zikuluzikulu zimafunikira kukhazikitsidwa. Chida chozizira chimatha kuchepetsa kutentha kwa upakati, ndipo kutentha kwa kutentha kwapamwamba kumatha kupewedwa kudzera mu kusakhazikika kwachilengedwe pambuyo pozizira.
