Ukuguquka Kwegunya LukaDlamini Kukugcina Ngaphandle Kwamanzi

Kutheni ukudala kwe-dlamini okuncane kanye nokunye kakhulu kwe-calcite kwenza kube nobuthakathaka obungcono ekuthinteni komrhuba

Imarbhile ihlala phakathi kuka 3 ukuya ku-4 kusika se-hardness ye-Mohs, lokhu kwenza kube yinqunyelwane ngaphandle kwegranite noma imitholwa yezinto ezenzakalelayo. Imarbhile yonke ihlanganisa izilungu eziningi ze-calcite, futhi known njenge-calcium carbonate. Xa kufika ekupholisini ngemithetho yomlilo, le ngxenye iyoba nguqondo olukhulu. Ukuhlukanana okweziphathepha zediamond kuphazanyiswa emperatshini yentonga iphumelela kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakhulu kakh......

Ukuthini ukuthi ukugcina ngomlilo kuyaholela kakhulu ekudaleni izinkinga zentonga nezinkinga zentonga

Lapho kungekho manzi okuthambisa, ukuchoboza kuba into elimazayo ngokuhamba kwesikhathi. Ukushisa okukhulu okukhiqizwayo empeleni kwenza izinto zande ngokungafani emgqeni wemvelo we-calcite, okuholela ekubumeni imifantu emincane kulo lonke itshe. Ngesikhathi esifanayo, lonke uthuli olusele lokushayela lubambeka phakathi kwamapulangwe futhi luqale ukusebenza njengama-particle amancane okubhubhisa isihlabathi. Lezi zingcezu ziyashabalala kuze kube yilapho sibona izimbobo zangempela zikhula. Okwenzeka lapha ngokuyisisekelo yizinkinga ezimbili ezisebenza ndawonye ukucindezeleka okushisayo okuvela ekushiseni kanye nokugqoka ngokomzimba okuvela emfucumfucwini. Lokhu kuhlanganiswa akwenzi izinto zibukeke zimbi nje kuphela empeleni kwenza yonke into ibe buthakathaka kakhulu. Lezo zingxenye ezincane ziya ngokuya ziba zijulile njalo lapho othile ephothula olunye uhlangothi lokucwenga, okwenza umonakalo ube mubi ngokwengeziwe njalo lapho ehla.

Indlela Ukusika Okuqinile Okulimaza Ngayo Ukusebenza Nokuphepha Kwama-Diamond Pad

Ukugqokwa kwe-pad, ukugqokwa ngaphambi kwesikhathi, nokulahlekelwa ukusebenza kahle kokusika ngaphandle kwamanzi

Xa kusetyenziswa ukugcina ngokushushu, wonke lo hlukahluka lukhula ubudlebe obukhulu obuyakhiqiza "ubunzima" okuthiwa yi "glazing". Le vili enjengwe yeglasu ibuyakhula izinxalenye zokugcina futhi ingasusa ubusebenzi kabini noma kangakanani kakhulu ezinye izimo. Izipadi zokugcina ziyashisa kakhulu kancane, okwenzela ukuba zilahlekelwe khona kunalokhu kufanelekile. Sifindile ukuthi kudingeka zishintshelwe ngamathathu njengoba kusebenza ngaphandle kokulubala. Ngaphandle kokulubala okufanelekileyo, kukhona kuphela ukuphazanyika okuningi kumongo. Abasebenzisi baphoqa kakhulu kunabo kufanele, okubangela iingxaki ezifana nokuchithwa kwemilenze, imigqa engalingani, kwaye umarble wokugcina waphula kakhulu ngaso sonke isixhobo.

Imida ye-Respirable Crystalline Silica (RCS) ekhokelela ukuthi usebenzise izipadi ze diamond ngokushushu

Xa abasebenzi bahlaka izinzu ezisuselwe, bavuselela izinkomba ezincane zokudonsa ebitwa ngokuthi respirable crystalline silica (RCS). Lezi zinkomba zingaphansi kwe-4 microns okusho ukuthi zingasekho phakade emlonyeni futhi zilungele ububi obubandayo, obugcwele ngokuphindaphindile. I-Occupational Safety and Health Administration yafumana ukuthi ukuhlaka kwesikhashana kwenza izilica ze-silica eziphazanyayo ngaphezulu kuka-12 okulinganayo ngezindlela zomvumo. Kanti? Abasebenzi amandla ayedwa ahlala aphinde aphinde amandla abulawa ngemva kokusha koku-15 xa esebenzisa lezi zindlela zesisikhashana. Uma akukho umvumo ofanelekile wamanzi ngduring ukusebenza kokuhlaka, abasebenzi basebhekene nomdla omkhulu wekuwanda silicosis. Lokhu akukhathaleki kuphela kwalabo kodwa kwenza iingxaki ezikhulu yokuhlanganiswa kubalawuli basephakathi bonke abadinga ukulandela iistandatha ezithintele ekufeni komsebenzi.

Ukucindezelwa Kwamanzi: Isidingo Esingenalo Ukungahlekelwa Ekuhlakeni Kwemarble

Umthwalo odlulayo ngokudlulayo kumakalabe ngenkathi kusolwa kwenza izinto ezimbili ebalulekile kakhulu. Okokuqala, ususa umthwalo ovela kumthwalo ngokushesha. Lokhu kumphela ukuthi makalabe athathe isibhedlela esiyisurfesi, okungakhiwa kuzokhula isimo sakhe esifanayo nokukhanya komthombo. Okwesibili, umthwalo ungamukela ukuphazamiseka kwezimali eziphezulu zomthwalo othile okungeke abasebenzi baphunye. Uyamgcina lezi ziphazamiso eziphansi ngaphambi kokuba zingene emthwale. Noma kunjalo uma akukho mthwalo ukulima, izinhloso zamakalabe zingafinyelela kakhulu kakhulu kulinganayo 150 degrees Celsius ngemizuzwana engu-2. Kule mihla, into eyaziwa ngokuthi calcite iqala ukuhluka kudala, kuyayihlukanisa ubume bezindlu.

Ukuthini umthwalo odlulayo ukulima kuyasusa umthwalo kanye nokumgcina izimali

Amaduze afundisa izinkumbulo ezimbili eziphambene ngexesha lefunda kuyiyo yasendle, kwaye nakuba yenza ukuba kube lula phakathi kwezinto. Xa i-diamond pads iphinde iphinde, iyenza indawo encinci yamaduze efaka umthwalo wokunqula ngokulula. Lokhu kusiza ekukhupheleni umthwalo ozenzekelayo apho isitya ziphumela ne-pad, kuthatha ubude obungcono bokulinganisa okuqukethwe ku-80 degrees Celsius. Okuqukethwe kusiza ekukhuseleleni iqondo lemarble ukungabikwa. Ngokufanayo, amaduze ayenza into esithi yi-slurry mixture eyayikhipha izinto ezincinci zezindlebe. Oku kubaluleke kakhulu ngoba ungaba nempilo yokudla izinto eziphathelene nokudla njengoko kuchazwe kumehluko yemfundo engama-years.

Ukugcinwa kwezulu kanye nezilinganiso zokudluliswa kuzo kuzenzekelayo kuzo lonke uhlobo lwesizathu kanye nezidingo

Ukugcinwa kwezulu kudinga ukuphatha kahle kwamaduze:

• Izilinganiso zokudluliswa : 0.5–1 liter/ngqezi ngendlela yonqulo encinci
• UMDLULO : 20–40 PSI ukuze kube yonke ngaphandle kokudlala

Ukudla okuncane kakhulu kusabela ukuglazwa kwamapadi nokuthinta izikhathi ezincane zokwephukela; amanzi amnandi akhuphuka izinkinga zokuphulula futhi akhubaza ukungena kwesilusi. Ukunqobela kahle kukhathaze iminyaka yophuthulo we-diamond pad ngakwekhaya futhi kuhlinza ukutholakala okumangalisayo okungapheli ngekuhlinzeka kwesiphiqo futhi kugcine ukuthola kwesibhedele esigcwele.

Isikhombisi Sokuqala

Kungani umarble uphawula kakhulu ekugcineni ngaphandle komsholo?

UMarble uphansi kakhulu futhi unezinkinga eziningi ze-calcite, kanti kuphawula ekugcineni uma usiphazamo isivuno sangaphakathi kusabela intonga yesandla.

Kuzikhiye ziphi izimali eziphathelene nesiseko sangaphakathi se-diamond pad?

Umsebenzi wokusebenzisa i-diamond pad engaphantsi komsholo kakhuthaza ukutholakala kwe-silica (RCS) esingaphethelwa, kubiza izinkinga zezempilo zomsebenzi futhi kube khona izinkinga zokuxhumana nezimvo zomphathi.

Kunjani amanzi athintela ekugcineni umarble?

Umthwalo omphakathi womsholo ungcwalisa intonga futhi ungcwalisa izinkomo, ukuze ungapheli futhi ungcwalise izinkinga zezempilo eziphathelene nesekutheni ngaphandle komsholo.
