Senzelwe ukuphelisa ukungaqondakali, ukuqinisekisa ukuba xa ucela umgangatho othile, ukuthamba, okanye ukugqitywa, ufumana kanye loo nto.
Isahluko 1: Ifiziksi yoZinzo – Kutheni iGranite?
Ngaphambi kokuba ujonge "indlela" yokuchazwa kweenkcukacha, kubalulekile ukuqonda "isizathu." I-granite echanekileyo—edla ngokumbiwa kwiindawo ezithile zejoloji ezityebileyo kwi-quartz kunye ne-feldspar—ikhethwa ngenxa yeempawu zayo zomzimba ezikhethekileyo. Xa ucacisa izinto, usebenzisa iimpawu ezintathu eziphambili:
Amandla okuDambisa
I-Granite ineempawu ezibalaseleyo zokudambisa ukungcangcazela. Kwi-machining ekhawulezayo okanye ekulinganiseni ngokuchanekileyo, ukungcangcazela kwangaphandle kutshaba. I-Granite ifunxa ezi ngcangcazelo endaweni yokuzithumela, iqinisekisa ukuba "ingxolo" ayichaphazeli ukuchaneka komlinganiselo okanye ukunqunyulwa.
Uzinzo lobushushu
Ngokungafaniyo nentsimbi, ekhula kwaye inciphe kakhulu xa kutshintshwe ubushushu, i-precision granite inomlinganiselo ophantsi wokwanda kobushushu. Okubaluleke ngakumbi, ine-thermal conductivity ephantsi. Oku kuthetha ukuba isabela kancinci kutshintsho lobushushu, inika isalathiso esizinzileyo sedatha nakwiindawo apho ulawulo lobushushu lungagqibelelanga.
Ayisebenzi ngemagnethi kwaye ayisebenzi ngemagnethi
Kwimizi-mveliso equka ukwenziwa kwezinto ze-elektroniki okanye oomatshini be-MRI, uhlobo lwe-granite olungengolwemagnethi alunakuxoxiswana ngalo. Luthintela ukuphazamiseka kwiindawo ze-electromagnetic ezibuthathaka.
Isahluko 2: Ukukhetha Udidi Lwezinto Ezifanelekileyo
Ayizizo zonke iigranite ezidalwe zilingana. Kwishishini, ngokubanzi sihlulahlula igranite echanekileyo ibe ziintlobo ezimbini eziphambili ngokusekwe kubuninzi, ubulukhuni, kunye nolwakhiwo lweenkozo. Ukuchaza uhlobo olungalunganga kunokukhokelela ekugugeni kwangethuba okanye ukuqina okunganelanga.
I-Black Granite (iGabbro/iGranite)
Idla ngokubizwa ngokuba yi "Black Granite" kurhwebo, le nto ngokwejoloji yi-gabbro. Ibonakala ngesakhiwo seenkozo esincinci kakhulu nesilinganayo.
- Eyona ilungele: Usetyenziso oluchanekileyo kakhulu olufana neetafile zeCoordinate Measuring Machine (CMM), oomatshini be-lithography abakumgangatho ophezulu, kunye neziseko ze-laser interferometry.
- Inzuzo ephambili: Inika ubunzima obuphezulu (Mohs 6-7) kunye nobuchule obuhle bokugqiba umphezulu. Ayinazo imingxuma ingako kunegranite engwevu.
Igranite epinki
Eli liqhinga lokusebenza kwezoshishino. Linomlinganiselo oqinileyo kancinci kunegranite emnyama kodwa linika uzinzo oluhle kakhulu.

Ingcebiso yeNkcazelo
Xa ubhala iSicelo sakho seNgqikelelo (RFQ), musa ukubhala nje “iGranite Base.” Cacisa: “Izinto: iNatural Black Granite (iGabbro), ecolekileyo, engenazimfanta, iintanda, kunye nezinto ezifakiweyo.”
Isahluko 3: Ubugcisa bokuPhucula uXinzelelo
Eyona ndawo ixhaphakileyo yokusilela kwizinto zegranite ezichanekileyo asikokuguguleka, kodwa kukugoba. Igranite lilitye lendalo eliphantsi koxinzelelo olukhulu lwejoloji. Ukuba olu xinzelelo lwangaphakathi alulawulwa ngexesha lenkqubo yokwenziwa, ilitye liya kuhamba emva kokuba lisetyenzisiwe ukuze linyamezeleke, nto leyo ebangela ukuba lingasebenzi.
Ukwaluphala Ngokwendalo
Oku kuquka ukumba ibhloko uze uyivumele ihlale ingabonakali kwimozulu kangangeenyanga okanye iminyaka. Nangona isebenza kakuhle, ithatha ixesha kwaye kunzima ukuyiqinisekisa.
Ukunceda ekuxinezelekeni okwenziweyo (Ukomisa kwiKiln)
Lo ngumgangatho weshishini weendawo ezichanekileyo. Ibhloko erhabaxa ifudunyezwa kwi-oven ekhethekileyo ukuya kubushushu obuthile (ngokuqhelekileyo malunga ne-500°C ukuya kwi-600°C) ize ipholiswe kancinci ngokwegophe elichanekileyo. Le nkqubo ilinganisa iminyaka yokwaluphala kwendalo kwiintsuku ezimbalwa.
Indlela yokuchaza
Kufuneka ufune isiqinisekiso senkqubo yokunciphisa uxinzelelo. Inkcazelo yakho mayifundeke ngolu hlobo: “Izinto ezisetyenzisiweyo mazincitshiswe ngoxinzelelo ngokomiswa kwi-oven. Umthengisi kufuneka anike ingxelo yokunciphisa uxinzelelo okanye isiqinisekiso sonyango.”
Isahluko 4: Ukuchaza Ukunyamezelana Kwejometri
Xa ujonga umzobo, "ukuthe tyaba" kunye "nokufana" kudla ngokuba ngamanani nje. Nangona kunjalo, kumxholo we-granite metrology, la manani achaza amandla omatshini.
Ukuthe tyaba
Le yindlela yokulinganisa ukuba umphezulu ugudile kangakanani. Kwigranite, oku kudla ngokuchazwa ngamabakala (umz., AA, A, B, 00) okanye ngama-microns athile kwindawo ethile.
- I-Nuance: Ipleyiti enkulu yomphezulu inokuba nokunyamezelana okuthe tyaba kwe-±5 microns, kodwa inqanaba elincinci lokuchaneka linokufuna i-±0.5 microns.
