Dhib malaha macaamilka cusub ama dukaameystaha duugoobay, Waxaan aaminsanahay muujinta dheer iyo xiriirka la aamini karo ee 2019 Darere Habaysan oo Tayo Sare leh ilaa Dareere si buuxda alxanka leh, Haddii aad xiisaynayso mid ka mid ah badeecadayada ama aad rabto inaad ka hadasho iibsi habaysan, adiga run ahaantii waa inaan dareemo xoriyad buuxda si aad noogu qabato.
Wax dhib ah maleh macaamil cusub ama dukaameystaha duugoobay, Waxaan aaminsanahay hadal dheer iyo xiriir la aamini karoKuleyliyaha iyo kuleyliyaha Shiinaha, In qarniga cusub, waxaan kor u our ruuxa ganacsiga "United, dadaalka badan, hufnaan sare, hal-abuurnimo", oo ku dheggan siyaasadeena"ku salaysan tayada, noqon ganacsi, dhufto ee brand fasalka koowaad". Waxaan ka faa'iidaysan lahayn fursadan dahabiga ah si aan u abuurno mustaqbal ifaya.
Kuleyliyaha garaafka
Qaybaha kuleyliyaha garaafka waxaa loo isticmaalaa foornada heerkul sare oo heerkulku gaaray 2200 darajo deegaanka faakuumka iyo 3000 digrii ee deoxidized iyo deegaanka gaaska la geliyo.
Tilmaamaha ugu muhiimsan ee kuleyliyaha garaafka:
1. isku mid ahaanshaha qaab dhismeedka kuleylka.
2. koronto wanaagsan iyo culeys koronto oo sarreeya.
3. iska caabin daxalka.
4. oksidizability.
5. nadiifinta kiimikada sare.
6. xoogga farsamada sare.
Faa'iidada waa tamar hufan, qiimo sare iyo dayactir hooseeya.
Waxaan soo saari karnaa ka-hortagga oksaydhka iyo cimriga dheer ee garaafiga crucible, caaryada garaafka iyo dhammaan qaybaha kuleyliyaha garaafka.
