Nka gikoresho gikomeye cyifashishwa mu gupima neza, granite slabs 'kwambara birwanya ubuzima bwabo bwa serivisi, ibipimo bifatika, hamwe nigihe kirekire. Ibikurikira birasobanura muburyo bwingenzi ingingo zingenzi zo kurwanya imyambarire yabo ukurikije ibintu bifatika, uburyo bwo kwambara, ibyiza byo gukora, ibintu bigira ingaruka, hamwe nuburyo bwo kubungabunga.
1. Ibyiza Byibikoresho no Kwambara Ibyingenzi
Gukomera kwiza nuburyo bwuzuye
Icyapa cya Granite kigizwe ahanini na pyroxene, plagioclase, hamwe na biotite nkeya. Binyuze mu gusaza karemano karemano, batezimbere imiterere-yuzuye, igera kuri Mohs ubukana bwa 6-7, ubukana bwinkombe burenga HS70, nimbaraga zo kwikuramo 2290-3750 kg / cm².
Iyi microstructure yuzuye (kwinjiza amazi <0,25%) itanga uburyo bukomeye bwo guhuza ibinyampeke, bigatuma habaho guhangana nubutaka hejuru kurenza icyuma (gifite ubukana bwa HRC 30-40 gusa).
Gusaza Kamere na Stress Imbere Kurekura
Ibisate bya Granite biva mubutaka bwiza bwo munsi y'ubutaka. Nyuma yimyaka miriyoni yubusaza karemano, imihangayiko yose yimbere yararekuwe, bivamo kristu nziza, yuzuye hamwe nuburyo bumwe. Uku gushikama gutuma kutagabanuka cyane kuri microcrack cyangwa deformasiyo kubera ihindagurika ryimyitwarire mugihe kirekire ikoreshwa, bityo bikagumya kwihanganira kwambara mugihe runaka.
II. Kwambara Imikorere nuburyo bukora
Impapuro zambara
Kwambara Abrasive: Micro-gukata iterwa nuduce duto duto kunyerera cyangwa kuzunguruka hejuru. Ubukomezi bukomeye bwa Granite (buhwanye na HRC> 51) butuma bwikuba inshuro 2-3 kwihanganira ibice byangiza kurusha ibyuma, bigabanya cyane ubujyakuzimu.
Kwambara bifata: Kwimura ibintu bibaho hagati yimiterere yumuvuduko mwinshi. Imiterere ya Granite idafite ibyuma (idafite magnetiki na disiki idafite plastike) irinda icyuma kugeza ku cyuma, bikavamo igipimo cyo kwambara hafi ya zeru.
Kwambara umunaniro: Gukuramo hejuru biterwa no guhangayika. Modulus ya Granite ihanitse cyane (1.3-1.5 × 10⁶kg / cm²) hamwe no kwinjiza amazi make (<0.13%) bitanga imbaraga zo kurwanya umunaniro mwiza, bigatuma ubuso bugumana ububengerane bumeze nkindorerwamo na nyuma yo kubikoresha igihe kirekire.
Imikorere isanzwe yamakuru
Ibizamini byerekana ko icyapa cya granite gifite uburambe bwa 1 / 5-1 / 3 gusa kwambara icyuma gikozwe mucyuma kimwe.
Ubusumbane bwubuso Ra agaciro guma guma guma mumwanya wa 0.05-0.1μm mugihe kirekire, cyujuje ibyiciro 000 bisabwa neza (kwihanganira uburinganire ≤ 1 × (1 + d / 1000) μ m, aho d nuburebure bwa diagonal).
III. Ibyiza Byibanze byo Kwambara Kurwanya
Coefficient nkeya yo Kwishongora no Kwisiga
Ubuso bwa Granite buringaniye, hamwe na coefficient de friction ya 0.1-0.15 gusa, itanga imbaraga nke mugihe gupima ibikoresho byanyuze hejuru yacyo, bikagabanya igipimo cyo kwambara.
Kamere idafite amavuta ya Granite ikuraho imyenda ya kabiri iterwa numukungugu wamamajwe namavuta, bigatuma amafaranga yo kubungabunga agabanuka cyane ugereranije nibyuma (bisaba gukoresha amavuta arwanya ingese).
Kurwanya Ruswa Yangiza na Rusi
Imikorere ihebuje (nta ruswa iri hagati ya pH ya 0-14), ibereye gukoreshwa mubushuhe nubumara.
Ibintu birwanya ingese bikuraho ubuso buterwa no kwangirika kwicyuma, bikavamo igipimo cyo guhinduka kwa <0.005mm / umwaka nyuma yo gukoresha igihe kirekire.
IV. Ibintu by'ingenzi bigira ingaruka kumyambarire
Ubushyuhe bwibidukikije nubushuhe
Imihindagurikire yubushyuhe (> ± 5 ° C) irashobora gutera kwaguka no kugabanuka, bitera microcrack. Ibidukikije byasabwe gukora ni ubushyuhe bugenzurwa na 20 ± 2 ° C hamwe nubushuhe bwa 40-60%.
Ubushuhe bwinshi (> 70%) bwihutisha kwinjira. Nubwo granite ifite umuvuduko muke wo gufata amazi, kumara igihe kinini mubushuhe birashobora kugabanya ubukana bwubutaka.
Umutwaro hamwe na Stress
Kurenza umutwaro wagenwe (mubisanzwe 1/10 cyingufu zo kwikuramo) birashobora gutera guhonyora. Kurugero, icyitegererezo cyicyapa cya granite gifite umutwaro wagereranijwe wa 500kg / cm². Mu mikoreshereze nyayo, ingaruka zinzibacyuho zirenze iyi gaciro zigomba kwirindwa.
Ikwirakwizwa ryimyitwarire idahwitse yihutisha kwambara. Inkunga y'ingingo eshatu cyangwa igabanijwe kimwe igishushanyo mbonera kirasabwa.
Kubungabunga no Gusukura
Ntukoreshe icyuma cyuma cyangwa ibikoresho bikomeye mugihe cyoza. Koresha umwenda utarimo umukungugu wuzuyemo inzoga ya isopropyl kugirango wirinde gutaka hejuru.
Buri gihe ugenzure ubuso bukabije. Niba agaciro ka Ra karenze 0.2 mm, gusubiramo no gusana birakenewe.
V. Ingamba zo Kubungabunga no Gutezimbere Kwambara Kurwanya
Gukoresha neza no Kubika
Irinde ingaruka zikomeye cyangwa ibitonyanga. Ingufu zingaruka zirenze 10J zishobora gutera gutakaza ingano.
Koresha inkunga mugihe cyo kubika hanyuma utwikire hejuru na firime itagira umukungugu kugirango wirinde ivumbi kwinjira muri micropores.
Kora Calibration isanzwe
Reba neza hamwe nurwego rwa elegitoronike buri mezi atandatu. Niba ikosa rirenze urugero rwo kwihanganira (urugero, ikosa ryemewe ku isahani yo mu cyiciro cya 00 ni ≤2 × (1 + d / 1000) μm), subira mu ruganda kugirango utegure neza.
Koresha ibishashara birinda mbere yo kubika igihe kirekire kugirango ugabanye ibidukikije.
Uburyo bwo Gusana no Gusubiramo
Kwambara hejuru <0.1mm birashobora gusanwa mugace hamwe na diyama abrasive paste kugirango igarure indorerwamo ya Ra ≤0.1μm.
Kwambara cyane (> 0.3mm) bisaba gusubira mu ruganda kugirango wongere usya, ariko ibi bizagabanya umubyimba rusange wisahani (intera imwe yo gusya ≤0.5mm).
Kwambara kwangirika kubisate bya granite bituruka kubufatanye hagati yimiterere yimyunyu ngugu no gutunganya neza. Muguhindura ibidukikije bikoreshwa, kugena uburyo bwo kubungabunga no gukoresha tekinoroji yo gusana, irashobora gukomeza kwerekana ibyiza byayo byukuri kandi biramba murwego rwo gupima neza, bigahinduka igikoresho ngenderwaho mubikorwa byinganda.
