Kuyini ukumelana kwe-acid-alkali kwezingxenye ze-granite ezinembile?

Izingxenye ze-precision granite zisetshenziswa kakhulu ekulinganisweni kokunemba kanye nokusetshenziswa kobunjiniyela, ngenxa yezakhiwo zazo ezihlukile zemishini. Zaziwa ngokuba namandla kakhulu futhi ziqinile, zinokukhula okuphansi kokushisa kanye nokumelana okuhle kakhulu nokuguguleka nokuklwebheka. Kodwa-ke, esinye sezimpawu ezingaziwa kakhulu zezingxenye ze-precision granite ukumelana kwazo okuphawulekayo kwe-acid-alkali.

Ukumelana ne-asidi-alkali yikhono lento ethile lokumelana nemiphumela yokugqwala kwezixazululo ze-asidi ne-alkali. Ezindaweni eziningi zezimboni nezamalebhu, izinto zichayeka ezinhlobonhlobo zama-asidi nama-alkali ngendlela yokuhlanza nokucubungula izixazululo. Izinto ezingamelani nala makhemikhali zingaba nomonakalo omkhulu noma ukwehluleka, okuholela ekulungisweni okubizayo kanye nesikhathi sokungasebenzi.

I-Granite iyidwala eliyi-igneous elakhiwe ngamakristalu axhumene amaminerali afana ne-feldspar, i-quartz, ne-mica. Lawa maminerali anika i-granite amandla nobunzima bayo obuhlukile, futhi ayenza imelane kakhulu nezixazululo ze-asidi ne-alkali. I-Granite yakhiwe ikakhulukazi ngama-silicates, azinzile ngamakhemikhali futhi angangeni. Uma evezwe ku-asidi noma ku-alkali, amaminerali e-silicate ku-granite awasabela ngamakhemikhali, okusho ukuthi izinto zihlala ziphelele futhi zingonakalanga.

Ukumelana ne-acid-alkali kwezingxenye ze-granite ezinembile kukhuliswa kakhulu ngezinqubo ezahlukahlukene zokukhiqiza. Ngesikhathi senqubo yokupholisha, ubuso be-granite buphathwa nge-sealing agent ethuthukisa ukumelana kwayo nokuhlaselwa ngamakhemikhali. Lesi sivalo sigcwalisa izikhala ezincane kanye nemifantu ebusweni be-granite, sakha isithiyo esivikelayo esivimbela i-acid noma i-alkali ukuthi ingene ezintweni.

Esinye isici esibalulekile esithonya ukumelana kwe-acid-alkali kwezingxenye ze-granite eziqondile yi-porosity yazo. I-porosity ibhekisela enanini lesikhala esivulekile noma izikhala phakathi kwezinhlayiya ze-granite. Uma i-porosity ye-granite iphansi, kulapho ukumuncwa kwayo koketshezi kuncipha khona. Lokhu kubalulekile, njengoba noma yikuphi uketshezi olumuncwa yi-granite lungasabela namaminerali angaphakathi kwetshe futhi lonakalise izakhiwo zalo. Izingxenye ze-granite eziqondile zenziwa nge-porosity ephansi kakhulu ukuqinisekisa ukumelana okuphezulu kumakhemikhali.

Ukumelana ne-acid-alkali kwezingxenye ze-granite eziqondile kuyisici esibalulekile ezimbonini eziningi ezidinga ukunemba okuphezulu nokunemba, njenge-metrology, i-optics, ukukhiqizwa okuqondile, kanye nokukhiqizwa kwe-semiconductor. Kulezi zimboni, ukunemba kubaluleke kakhulu. Noma yiziphi izinguquko ezincane ezimpahleni zemishini yazo zingaba nomthelela omkhulu emiphumeleni yazo. Ngokusebenzisa izingxenye ze-granite eziqondile, lezi zimboni zingaqiniseka ukuthi imishini yazo imelana nemiphumela yokugqwala yamakhemikhali, okuholela ekunembeni okukhulu, ekuthembekeni nasekuqineni.

Ekuphetheni, izingxenye ze-precision granite zibonisa ukumelana okungavamile kwe-acid-alkali ngenxa yokwakheka kwazo okuhlukile kanye nezinqubo zokukhiqiza. Ukumelana kwe-acid-alkali kwezingxenye ze-precision granite kungenye yezinto eziningi ezenza zibe yinto efanelekile yokusetshenziswa okunembe kakhulu. Njengoba izimboni ziqhubeka nokufuna ukunemba okukhulu nokuthembeka emishinini yazo, izingxenye ze-precision granite zizohlala ziyingxenye ebalulekile ezikhalini zazo.
