Zolembera nthawi zonse zinali ngati chizindikiro cha kukoma kwabwino. Pogwirizana ndi mfundo zina, zoperekera siliva zidalandiridwa kuti ziperekedwe ndi cholowa kapena kuperekedwa mwakhama kwambiri. Za momwe mungasankhire siliva yoyenera, tidzakambirana lero.
Kudulidwa kwa siliva - zovuta za kusankha
Khwerero 1 - fotokozerani ndi kumaliza
Pogulitsa, mungapeze ma tebulo a siliva, opangidwa ndi chiwerengero chosiyana cha zinthu, zokonzedwa kwa anthu 6 ndi 12. Kuwonjezera pa zipangizo zazikulu zomwe zimagwiritsidwa ntchito mwachindunji pa chakudya, izi zimaphatikizapo zipangizo zothandizira, zomwe cholinga chake ndicho kusinthitsa chakudya kuchokera ku zida zambiri kwa munthu aliyense: zikhomo, forceps, ndi zina zotero.
Khwerero 2 - samverani chizindikiro
Tiyeni tipange nthawi yomweyo kuti tebulo la siliva lisakhalenso siliva mu mphamvu ya mankhwala ya mawu. Zida zopangidwa ndi siliva wangwiro zimakhala zofewa ndipo zimataya mwamsanga mawonekedwe ndi mawonekedwe akunja, zophimbidwa ndi mano ndi zowonongeka. Kwa zaka zopitirira mazana awiri, chodulira chapangidwa kuchokera ku chomwe chimatchedwa siliva wosasunthira - chokhala ndi siliva ndi mkuwa. Chilogalamu imodzi ya alloy chotero ili ndi 925 magalamu a siliva ndi 75 gm zamkuwa (925). Pogulitsa, mungapeze mankhwala omwe amapanga magalasi 800 magalamu a siliva ndi 200 magalamu a mkuwa (zitsanzo 800). Tiyenera kuganiziridwa kuti malinga ndi muyeso mu Russia, mankhwala opangidwa ndi alloy omwe ali ndi ndalama zosachepera 800 pa magawo 1000 a alloy omwe saganiziridwa kuti ndi amtengo wapatali, choncho sagonjetsedwa. Zida zopangidwa ndi siliva zalembedwa ndi nambala kuyambira 90 mpaka 150, zomwe zimasonyeza kuti magalamu angapo a siliva amagwiritsidwa ntchito kuphimba zinthu 12 (zikho, mafoloko, etc.).
Khwerero 3 - timayang'ana kunja
Pambuyo poyesa zitsanzo ndi zolemba, timayang'ana kunja kwa siliva yosankhidwa. Zilibe kanthu kaya mumasankha ndalama ziti zasiliva zomwe munasankha - ana, kwa anthu 6 kapena 12 - zinthu zonsezi siziyenera kukhala ndi ziphuphu, chips, madontho ndi zikopa. Zomwe zimapangidwira pazitsulo zonse zayikidwa ziyenera kukhala zofanana. Zidutswa za "zolondola" zikho ndi mafoloko zimakhala zooneka bwino kuphula, ndipo makulidwe awo sayenera kukhala osachepera 2 mm. Kuya kwa makapu ayenera kukhala 7 mpaka 10 mm.
Kodi mungasamalire bwanji siliva?
Kudulidwa kwa siliva kumangokhala kuwonongeka kwa chilengedwe, kotero amafunikira chisamaliro chapadera ndi mosamala. Choncho, poyeretsa ndi kofunika kugwiritsa ntchito njira yapadera, ndipo mutatha kuzigwiritsa ntchito ndikofunika kuti muwume wouma. Sambani zipangizo zasiliva ndi manja, kutsukidwa pamapeto ndi madzi ozizira.
