Iyintoni ukumelana kwe-acid-alkali kwezinto zegranite ezichanekileyo?

Izinto zegranite ezichanekileyo zisetyenziswa kakhulu kwi-precision metrology kunye ne-engineering applications, ngenxa yeempawu zazo ezibalaseleyo zoomatshini. Zaziwa ngokuba namandla kakhulu kwaye ziqinile, zinokwanda okuphantsi kobushushu kunye nokumelana okuhle nokuguguleka. Nangona kunjalo, enye yezona mpawu zingaziwayo zezinto zegranite ezichanekileyo kukumelana kwazo okumangalisayo kwe-acid-alkali.

Ukumelana ne-asidi-alkali kukukwazi kwezinto ukumelana nemiphumo yokubola kwezisombululo ze-asidi kunye ne-alkali. Kwiimeko ezininzi zoshishino nezelebhu, izixhobo zichatshazelwa kuluhlu olubanzi lwee-asidi kunye ne-alkali ngendlela yezisombululo zokucoca nokucubungula. Izixhobo ezingamelaniyo nezi khemikhali zinokonakala kakhulu okanye zingasebenzi, nto leyo ekhokelela ekulungisweni okubizayo kunye nexesha lokungasebenzi.

I-Granite lilitye eliyi-igneous elenziwe ngeekristale ezidibeneyo zeeminerali ezifana ne-feldspar, i-quartz, kunye ne-mica. Ezi minerali zinika i-granite amandla ayo kunye nobunzima bayo, kwaye ziyenza imelane kakhulu nezisombululo ze-asidi kunye ne-alkali. I-Granite yenziwe ikakhulu zii-silicates, ezizinzileyo ngokweekhemikhali kwaye azinawo amandla. Xa zichatshazelwe kwi-asidi okanye kwi-alkali, iiminerali ze-silicate kwi-granite azisabela ngokweekhemikhali, oko kuthetha ukuba izinto zihlala ziqinile kwaye zingonakalanga.

Ukumelana ne-acid-alkali kwezinto zegranite ezichanekileyo kuphucuka ngakumbi ngeenkqubo ezahlukeneyo zokuvelisa. Ngexesha lenkqubo yokupholisha, umphezulu wegranite uphathwa nge-arhente yokutywina ephucula ukumelana kwayo nohlaselo lweekhemikhali. Le sealant izalisa iimbobo ezincinci kunye neengxondorha kumphezulu wegranite, yenze umqobo okhuselayo othintela i-acid okanye i-alkali ukuba ingangeni kwizinto.

Enye into ebalulekileyo echaphazela ukumelana ne-acid-alkali kwezinto zegranite ezichanekileyo kukuxinana kwazo. Ukuxinana kubhekisa kubungakanani bendawo evulekileyo okanye izithuba phakathi kweenkozo zegranite. Okukhona ukuxinana kwegranite kuphantsi, kokukhona ukuxinana kwayo kolwelo kuphantsi. Oku kubalulekile, njengoko naluphi na ulwelo olufunxwa yigranite lunokusabela kunye neeminerali ezikwilitye kwaye lonakalise iimpawu zalo. Izinto zegranite ezichanekileyo zenziwe nge-porosity ephantsi kakhulu ukuqinisekisa ukumelana okuphezulu kwiikhemikhali.

Ukumelana ne-acid-alkali kwezinto zegranite ezichanekileyo yinto ebalulekileyo kumashishini amaninzi afuna ukuchaneka okuphezulu nokuchaneka, njenge-metrology, i-optics, imveliso echanekileyo, kunye nemveliso ye-semiconductor. Kule mashishini, ukuchaneka kubaluleke kakhulu. Naluphi na utshintsho oluncinci kwiimpawu zezixhobo zabo lunokuba nefuthe elikhulu kwiziphumo zabo. Ngokusebenzisa izinto zegranite ezichanekileyo, la mashishini anokuqinisekiswa ukuba izixhobo zawo ziyamelana nemiphumo yokubola yeekhemikhali, nto leyo ekhokelela ekuchanekeni okukhulu, ekuthembekeni, nasekuqineni.

Ukuqukumbela, izinto zegranite ezichanekileyo zibonisa ukumelana okugqwesileyo kwe-acid-alkali ngenxa yokwakheka kwazo okwahlukileyo kunye neenkqubo zokuvelisa. Ukumelana kwe-acid-alkali kwezinto zegranite ezichanekileyo yenye yezinto ezininzi ezenza zibe zizinto ezifanelekileyo zokusetyenziswa ngokuchanekileyo. Njengoko amashishini eqhubeka nokufuna ukuchaneka okukhulu kunye nokuthembeka kwizixhobo zawo, izinto zegranite ezichanekileyo ziya kuhlala ziyinxalenye ebalulekileyo kwizixhobo zawo.
