Beryllium ọla kwesịrị ịbụ ihe ọhụrụ nye onye ọ bụla, ọ bụkwa ihe na -eme ka mmiri na -eme ka mmiri sie ike. Isiokwu a na -akọwakarị ụzọ nhazi atọ nke ọla kọpa beryllium.

(1) Ngwọta ọgwụgwọ ọla kọpa beryllium

Na mkpokọta, okpomoku ọkụ nke ọgwụgwọ ọgwụgwọ dị n'etiti 780-820 ℃. Maka ihe eji eme ka ihe na-agbanwe agbanwe, a na-eji 760-780 to gbochie ọka siri ike imetụta ike. Ekwesịrị ijikwa ịdị n'otu okpomọkụ nke ọkụ ọgwụgwọ ọgwụgwọ na ± 5 Celsius C. Enwere ike gbakọọ oge njigide dị ka elekere 1 / 25mm. Mgbe a na -edobe ọla kọpa beryllium na ọgwụgwọ ikuku ma ọ bụ ikuku ikuku, a ga -emepụta ihe nkiri oxide n'elu. Agbanyeghị na ọ nwere obere mmetụta na akụrụngwa arụ ọrụ mgbe emechara nká, ọ ga -emetụta ndụ ọrụ nke ngwaọrụ n'oge arụ ọrụ oyi. Iji zere ịzere oxidation, ekwesịrị itinye ya n'ime ọkụ ọkụ ma ọ bụ mbibi amonia, gas inert, na -ebelata ikuku (dịka hydrogen, carbon monoxide, wdg), iji nweta mmetụta ọgwụgwọ ọkụ na -enwu gbaa. Tụkwasị na nke a, attentionaa ntị na ibelata oge mbufe (mgbe ị na -emenyụ) ka o kwere mee, ma ọ bụghị ya, ọ ga -emetụta akụrụngwa n'arụ ọrụ mgbe ịka nká. Ihe dị mkpa ekwesịghị gafere sekọnd 3, akụkụ izugbe ekwesịghị ịfega sekọnd 5. Ọkụ na -agbanyụ ọkụ na -ejikarị mmiri (na -enweghị ihe chọrọ ọkụ), n'ezie, akụkụ dị mgbagwoju anya nwekwara ike iji mmanụ iji zere nrụrụ.

(2) Ọgwụ ịka nká nke ọla kọpa beryllium

Ọnọdụ ịka nká nke ọla kọpa beryllium metụtara ọdịnaya nke Be, na alloys nwere Be erughị 2.1% dabara maka ọgwụgwọ ịka nká. Maka alloys nke nwere ihe karịrị 1.7%, ọnọdụ ịka nká kacha mma bụ 300-330 ℃, oge ijide ya bụ awa 1-3 (dabere n'ụdị na ọkpụrụkpụ akụkụ). Alloys electrode na-arụ ọrụ nke ukwuu dị n'okpuru 0.5%, n'ihi mmụba na ebe mgbaze, okpomọkụ kacha mma ịka nká bụ 450-480 ℃, yana oge ijide bụ awa 1-3. N'ime afọ ndị na-adịbeghị anya, etolitekwara ịka nká abụọ na ọtụtụ ogbo, ya bụ, ịka nká na-adịte aka na oke okpomoku yana ịka nka ogologo oge na obere okpomọkụ. Uru nke a bụ na arụmọrụ ka mma mana nkwarụ na -ebelata. Iji meziwanye nha nke ọla kọpa beryllium mgbe ịka nká, enwere ike iji mwekota maka ịka nká, na mgbe ụfọdụ enwere ike iji ọgwụgwọ ịka nká abụọ dị iche.

(3) Nchekasị nke ọla kọpa beryllium

Beryllium ọla kọpa nwere okpomọkụ annealing nke 150-200 ° C yana oge njigide nke awa 1-1.5.Ọ nwere ike iji wepu nchekasị fọdụrụ site na ịkpụ ọla, ịgbatị, akpụ oyi, wdg, wee mee ka ọdịdị na izi ezi nke akụkụ ahụ sie ike. nke akụkụ n'oge eji ogologo oge.

Mgbe Ngwongwo ọla kọpa ngwọta na ịka nká, ike nwere ike iru 1250-1500MPa (1250-1500 n'arọ). A na -eji ọgwụgwọ ọkụ ya mara ezigbo plastik mgbe ọgwụgwọ ngwọta na nkwarụ oyi. Otú ọ dị, mgbe ọgwụgwọ ịka nká, ọ nwere oke mgbatị na -esiwanye ike na ike ka mma.
