Jalaato Mica ah: Jalaato Mica ah oo dabiici ah, jalaato Mica midab leh, jalaato Mica ah oo synethic ah.

Mica waa qayb muhiim ah oo ka mid ah isku-dhafka dhagaxa dabiiciga ah. Qaybaha dhagaxa dabiiciga ah waxay leeyihiin midab adag, iska caabinta biyaha iyo jilitaanka, iyo iska caabin heer sare ah iyo iska caabin qabow. Ma aha kuwo dhegdheg leh kulaylka, jilicsan qabowga, hodan ku ah midabka, dhalaalaya midabka, iyo awood u leh balaastikada. Waa lammaane aad u fiican oo soo saara rinjiga dhagaxa dhabta ah iyo rinjiga granite, waana agab qurxin cusub oo leh sifooyin saddex-geesood ah oo xooggan oo loogu talagalay rinjiga derbiga gudaha.

Jajabyada mica ee isku dhafan ayaa lagu dari karaa oo lagu qasi karaa rinjiyo dhagax oo kala duwan oo biyo ku salaysan (rinjiyada dhagaxa dhabta ah) oo leh saami gaar ah, si rinjiyada dhagaxa dhabta ah ee caadiga ah loogu rogi karo rinjiyo granite heer sare ah (rinji); Si loo gaaro saameynta cajiibka ah ee qaab-dhismeedka dhagaxa granite dabiiciga ah, iyadoo loo eegayo cabbirka walxaha midabka ee dhagaxa granite dabiiciga ah, xaleefyada dhagaxa isku dhafan waxaa laga sameeyaa xaashiyo jilicsan oo aan caadi ahayn oo dhumucdoodu tahay 0.3 mm, sida 1-3 mm, 1-5 mm, 1-8 mm, 1-10 mm, 1-12 mm, iwm.

Jajabyada mica ee isku dhafan waa walxo muhiim u ah soo saarayaasha rinjiga granite (rinjiga). Soo saarayaasha rinjiga dhagaxa waxay dooran karaan midabka iyo cabbirka ku habboon ee jajabyada dhagaxa isku dhafan iyadoo loo eegayo midabka iyo cabbirka walxaha dhagaxa granite-ka dabiiciga ah, waxayna ku dari karaan rinjiga dhagaxa dabiiciga ah iyadoo loo eegayo saami gaar ah (iyadoo loo eegayo waxa ku jira walxaha midabka leh ee ku jira dhagaxa granite-ka dabiiciga ah), waxayna si siman isugu qasi karaan xawaare dhexdhexaad ah oo ah 5-10 daqiiqo si loo soo saaro rinji granite ah oo heer sare ah (rinji) iyadoo lagu saleynayo rinjiga dhagaxa.
