Dị ka ngwá ọrụ ntụaka dị oke mkpa na mpaghara nha nkenke, nkwụsi ike nke granite na-ekpebi ndụ ọrụ ha, nha nha nha na nkwụsi ike ogologo oge. Ndị na-esonụ na-akọwa n'usoro n'usoro isi isi ihe na-eguzogide iyi ha site n'echiche nke ihe onwunwe, usoro ejiji, uru arụmọrụ, ihe ndị na-emetụta, na atụmatụ nlekọta.
1. Ngwongwo ihe na ihe mgbochi iyi
Ezi isi ike na nnukwu Ọdịdị
Ihe mejupụtara nke granite bụ pyroxene, plagioclase, na obere biotite. Site na ịka nká okike ogologo oge, ha na-etolite n'ụdị dị mma, na-enweta ike Mohs nke 6-7, ike siri ike nke Shore karịrị HS70, yana ike mkpakọ nke 2290-3750 kg/cm².
Nkịtị microstructure a siri ike (mmiri mmiri <0.25%) na-eme ka njikọ dị n'etiti ọka siri ike, na-ebute nguzogide ọkọchị elu nke ukwuu karịa nkedo ígwè (nke nwere isi ike nke naanị HRC 30-40).
Ịka nká na Mwepụta Nchegbu Ime
A na-enweta mbadamba nkume granite site na nhazi nkume dị n'okpuru ala dị elu. Mgbe ọtụtụ nde afọ nke ịka nká nke okike gasịrị, a tọhapụrụ nrụgide niile dị n'ime, na-ebute ọmarịcha kristal dị oke ọnụ na otu ụdị. Nkwụsi ike a na-eme ka ọ ghara ịdaba na microcracks ma ọ bụ nrụrụ n'ihi mgbanwe nrụgide n'oge a na-eji ogologo oge eme ihe, si otú a na-ejigide nguzogide iyi ya ka oge na-aga.
II. Yiri usoro na arụmọrụ
Ụdị ejiji isi
Abrasive Wear: Mkpịsị obere ihe na-akpata site na ụmụ irighiri ihe siri ike na-amịgharị ma ọ bụ na-atụgharị n'elu. Isi ike dị elu nke Granite (nke kwekọrọ na HRC> 51) na-eme ka ọ bụrụ ugboro 2-3 ka ọ na-eguzogide ihe na-ekpo ọkụ karịa ígwè nkedo, na-ebelata omimi omimi nke elu.
Uwe nrapado: Nbufe ihe na-eme n'etiti ebe kọntaktị n'okpuru nnukwu nrụgide. Ngwongwo ndị na-abụghị ọla nke Granite (na-abụghị ndọta na nrụrụ plastik) na-egbochi nrapanye igwe-na-metal, na-ebute oke nso-efu efu.
Yiri ike ọgwụgwụ: peeling n'elu nke nrụgide cyclic kpatara. Granite's high elastic modulus (1.3-1.5×10⁶kg/cm²) na obere mmiri absorption (<0.13%) na-enye ọmarịcha ike ọgwụgwụ, na-ekwe ka elu nọgide na-enwe a mirror-dị ka gloss ọbụna mgbe ogologo oge eji.
Data arụmọrụ ahụkarị
Nnwale na-egosi na slabs granite na-enweta naanị 1 / 5-1 / 3 iyi nke nkedo slabs n'okpuru otu ọnọdụ ọrụ.
Ọdịiche dị n'elu ọnụ ahịa Ra na-anọgide na-eguzosi ike n'ime 0.05-0.1μm ogologo ogologo oge, na-ezute klaasị 000 nkenke chọrọ (nlekọta ọnụ ≤ 1 × (1 + d / 1000) μm, ebe d bụ ogologo diagonal).
III. Isi uru nke Nguzogide eyi
Ọnụego esemokwu dị ala na mmanye onwe ya
Igwe dị larịị nke Granite, yana ọnụọgụ nke esemokwu nke naanị 0.1-0.15, na-enye obere nguzogide mgbe ị na-atụ ngwaọrụ na-agafe n'ofe ya, na-ebelata ọnụego uwe.
Ọdịdị na-enweghị mmanụ nke Granite na-ewepụ uwe nke abụọ nke uzuzu nke mmanu mmanu na-akpata na-akpata, na-ebute ụgwọ ọrụ nlekọta dị ala nke ukwuu karịa ihe nkedo ígwè (nke chọrọ itinye mmanụ mgbochi nchara mgbe niile).
Na-eguzogide ọgwụ corrosion na nchara
Ọmarịcha arụmọrụ (enweghị corrosion n'ime oke pH nke 0-14), dabara adaba maka iji na gburugburu iru mmiri na kemịkalụ.
Njirimara ndị na-eguzogide nchara na-ewepụ ihe nhụsianya elu nke metal corrosion na-akpata, na-ebute mgbanwe mgbanwe ọnụ nke <0.005mm / afọ mgbe ejiri ogologo oge mee ihe.
IV. Ihe ndị bụ isi na-emetụta nguzogide iyi
Okpomọkụ gburugburu na iru mmiri
Mgbanwe ọnọdụ okpomọkụ (> ± 5 ° C) nwere ike ime ka mgbasawanye na mkpụkọ ọkụ, na-ebute microcracks. Ebe a na-arụ ọrụ na-atụ aro bụ okpomọkụ a na-achịkwa nke 20 ± 2 ° C yana iru mmiri nke 40-60%.
Oke iru mmiri (>70%) na-eme ka ntinye mmiri dịkwuo elu. Ọ bụ ezie na granite nwere ọ̀tụ̀tụ̀ mmịpụta mmiri dị ala, ikpughe ruo ogologo oge na iru mmiri ka nwere ike ibelata isi ike elu.
Ibu na Kpọtụrụ Nchegbu
Ịgafe ibu akwadoro (nke na-abụkarị 1/10 nke ike mkpakọ) nwere ike ime ka egwepịa mpaghara. Dịka ọmụmaatụ, ụfọdụ ihe atụ nke slab granite nwere oke ruru 500kg/cm². N'iji ya eme ihe n'ezie, ekwesịrị ịzenarị ibu mmetụta na-agafe agafe karịa uru a.
Nkesa nrụgide kọntaktị na-ekwekọghị ekwekọ na-eme ka ike na-eyi ngwa ngwa. A na-atụ aro nkwado nke atọ ma ọ bụ na-ekesa ibu n'otu n'otu.
Nlekọta na nhicha
Ejila brọsh ígwè ma ọ bụ ngwaọrụ siri ike mgbe ị na-ehicha ya. Jiri akwa na-adịghị uzuzu kpuchie ya na mmanya isopropyl iji zere ịcha elu.
Na-eleba anya mgbe niile na ala adịghị mma. Ọ bụrụ na uru Ra karịrị 0.2μm, a ga-achọgharị ma rụkwaa ya.
V. Atụmatụ nlekọta na nkwalite maka nguzogide iyi
Eji na Nchekwa nke ọma
Zere mmetụta dị arọ ma ọ bụ tụda. Mmetụta ike gafere 10J nwere ike ibute mfu ọka.
Jiri nkwado n'oge nchekwa ma kpuchie elu ya na ihe nkiri na-ekpuchi uzuzu iji gbochie uzuzu ka ọ ghara ịbanye na micropores.
Mee nhazi nhazi oge niile
Jiri ọkwa eletrọnịkị lelee ịdị larịị kwa ọnwa isii. Ọ bụrụ na njehie ahụ gafere oke nnabata (dịka ọmụmaatụ, njehie a na-anabata maka efere 00-ọkwa bụ ≤2 × (1+d/1000) μm), laghachi na ụlọ ọrụ mmepụta ihe maka nhazi nke ọma.
Tinye wax nchebe tupu nchekwa ogologo oge iji belata mmebi gburugburu ebe obibi.
Usoro mmezi na nrụpụta
Enwere ike idozi akwa mkpuchi elu <0.1mm na mpaghara ya na tapawa abrasive diamond iji weghachi enyo enyo nke Ra ≤0.1μm.
Mwepu miri emi (> 0.3mm) chọrọ ịlaghachi na ụlọ ọrụ mmepụta ihe maka ịghagharị ọzọ, mana nke a ga-ebelata oke nha nke efere ahụ (ebe dị anya ≤0.5mm).
Nkwụsi ike nke slabs granite na-esi na mmekọrịta dị n'etiti ihe ndị na-emepụta ihe ndị sitere n'okike na nhazi nkenke. Site n'ịkwalite gburugburu ebe obibi, ịhazi usoro nhazi na ịnakwere teknụzụ nrụzi, ọ nwere ike ịga n'ihu na-egosipụta uru ya nke ezi izi ezi na ogologo ndụ na mpaghara nha nkenke, na-aghọ ngwá ọrụ benchmark na mmepụta mmepụta ihe.
