Mubasa rekugadzira maindasitiri, kushanda zvakanaka kwemidziyo ndiyo musimboti wekuona kugona kwayo kugadzira uye kushanda zvakanaka. Zvisinei, dambudziko rekuti michina haishande kwenguva yakareba nekuda kwengura yesimbi dzekare dzagara dzichishandiswa rave richitambudza indasitiri yekugadzira. Kubva pamidziyo yekuyera nemazvo kusvika kumidziyo inorema yemuchina, kana yangove nengura yesimbi, hazvizongogumiri pakuyera nekusakara kwezvikamu zvemuchina, asiwo zvinogona kukonzera kutadza kwemidziyo uye kukanganiswa kwekugadzirwa kwayo. Nzvimbo yegranite, ine hunhu hwayo hwekudzivirira ngura, inopa mabhizinesi mhinduro inongogara iripo.
Kuora kwezvigadziko zvesimbi: "Muurayi asingaoneki" mukugadzirwa kwemaindasitiri
Zvigadziko zvesimbi zvakakandwa zvaimboshandiswa zvakanyanya mumidziyo yakasiyana-siyana yeindasitiri nekuda kwemutengo wakaderera uye nyore kugadzira. Zvisinei, simbi yakakandwa isimbi-kabhoni alloy. Chimiro chayo chemukati chine huwandu hwakawanda hwemaburi madiki uye tsvina, izvo zvinowanzo kanganiswa nekuoxidation reactions nehunyoro neokisijeni mumhepo, zvichigadzira ngura. Munzvimbo dzakanyorova dzekushandira, munzvimbo dzegungwa dzine munyu wakawanda, kana kana dzakasangana nezvinhu zvakaita se coolant uye acid kana alkali cleaners, mwero wengura wezvigadziko zvesimbi zvakakandwa uchawedzera zvakanyanya. Zvichienderana nehuwandu, munzvimbo dzakajairika dzeindasitiri, zvigadziko zvesimbi zvakakandwa zvicharatidza ngura pachena paavhareji makore maviri kusvika matatu ega ega. Zvisinei, munzvimbo dzine hunyoro hwakawanda kana ngura, hupenyu hwayo hwekushanda hunogona kutopfupikiswa kusvika pasi pegore rimwe.
Mushure mekuora, pamusoro pechigadziko chesimbi yakakandwa chinozobvaruka zvishoma nezvishoma uye chinova chisina kuenzana, zvichikonzera kudzikira kwekunyatsorongeka kwemidziyo uye zvichikonzera matambudziko akadai sekubvunda kwakasimba uye zvikamu zvakasununguka. Pamidziyo yekuyera zvakarurama, kushanduka kudiki kunokonzerwa nengura pachigadziko kunogona kutungamira kuzvikanganiso zvekuyera zvichikwira kusvika kupfuura ±5μm, zvichiita kuti kuongororwa kwechigadzirwa kusave nemusoro. Pamidziyo yemuchina inorema, kukuvara kwechimiro kunokonzerwa nengura kunogona kutotungamira kudzima kwemidziyo kamwe kamwe, zvichikonzera kuoma kwemutsetse wekugadzira. Imwe fekitori yekugadzira zvikamu zvemota yakambotambura nekusashanda zvakanaka kwechishandiso chayo chekuyera chakarurama nekuda kwengura yechigadziko chesimbi yakakandwa. Kurasikirwa kwehupfumi kwakananga kunokonzerwa nenguva yekushanda kwemidziyo mukati megore kwakapfuura miriyoni imwe yeyuan.
Nheyo yegranite: "Nhoo yekudzivirira" yekudzivirira ngura yechisikigo
Granite idombo rechisikigo rakaumbwa kuburikidza nemaitiro e geological kwemazana emamiriyoni emakore. Makristaro ayo emukati mezvicherwa akanyatsogadzirwa, uye chimiro chayo chakasimba uye chakafanana, zvichiita kuti ive nebhenefiti yekudzivirira ngura. Zvikamu zvikuru zvegranite (quartz, feldspar, mica, nezvimwewo) zvine hunhu hwakagadzikana hwemakemikari uye hazvisangani nezvinhu zvakajairika zvine acidic kana alkaline. Kunyangwe zvikabata kwenguva refu nezvinwiwa zvinoparadza zvakaita se coolant uye cleansing agents, hapana ngura ichaitika. Pamusoro pezvo, pamusoro pegranite hapana maburi, uye mvura haigoni kupinda mukati, zvichibvisa mukana wekuti oxidation uye ngura ibve mumudzi.
Ruzivo rwekuyedza runoratidza kuti kana granite nesimbi yakakandwa zvikaiswa panguva imwe chete munzvimbo ine ngura yakawanda ine 10% sodium chloride solution, simbi yakakandwa inoratidza ngura dziri pachena mukati memaawa makumi mana nemasere, nepo mushure memaawa chiuru ekuyedzwa, pamusoro pegranite panoramba pakachena sepatsva pasina nyora dzengura. Kushanda uku kwakanaka kwekudzivirira ngura kunoita kuti mabhesi egranite aratidze mabhenefiti asingatsiviwi mumaindasitiri ane ngura dzakasimba dzakadai se chemical engineering, food processing, uye Marine engineering.
Kugadzirisa Mari Yehupenyu Hwakazara: Kubva pa "Kudyara Kwenguva Pfupi" kusvika pa "Kudzoka Kwenguva Refu"
Kunyangwe mutengo wekutanga wekutenga mabhesi egranite wakakwira kupfuura wesimbi yakakandwa, kubva pamaonero ehupenyu hwese hwemidziyo, mabhenefiti ainounza anopfuura musiyano wemutengo. Hwaro hwesimbi yakakandwa hunoda kugadziriswa nguva nenguva nekuda kwengura (sekubvisa ngura uye kupenda patsva), uye mutengo wekugadzirisa wegore negore unosvika 10% kusvika 15% yemutengo wekutenga. Kana ngura yacho yakanyanya, hwaro hwese hunoda kutsiviwa, izvo zvinowedzera zvakananga nguva yekushanda kwemidziyo uye mari yekutsiva. Hwaro hwegranite hahudi kugadziriswa, hune hupenyu hwebasa hwemakore anopfuura makumi maviri, uye hunochengetedza kururama kwakasimba uye mashandiro mukati mekushandiswa, zvichideredza kutadza kwemidziyo uye nguva yekushanda.
Mushure mekunge rimwe kambani yekugadzira zvemagetsi yatsiva hwaro hwesimbi yakakandwa yemutsetse wekugadzira nehwaro hwegranite, mwero wekushanda kwemidziyo wakaderera ne85%, kutenderera kwekuenzanisa kwemidziyo yekuyera kwakawedzerwa kubva kamwe chete pamwedzi kusvika kamwe chete pagore, uye mutengo wegore negore wakaderedzwa ne40%. Pamusoro pezvo, kugadzikana kwakanyanya kwehwaro hwegranite kwakawedzerawo mwero wekukodzera kwechigadzirwa, zvichigadzira mabhenefiti ehupfumi asina kunanga.
Mukuwedzera kwekuvandudzwa kwemidziyo yeindasitiri, kuchinja kubva pazvigadziko zvesimbi zvakakandwa kuenda kuzvigadziko zvegranite hakusi kungodzokorora zvinhu chete asiwo kusvetuka mupfungwa dzekugadzira kubva pa "kuita kuti zviitike" kuenda ku "kugona". Nekusarudza zvigadziko zvegranite, mabhizinesi haagone kugadzirisa dambudziko rengura nekuora chete, asiwo kuwana kuvandudzwa kaviri mukushanda zvakanaka kwekugadzira uye mabhenefiti ehupfumi kuburikidza nekushanda kwakagadzikana kwenguva refu kwemidziyo, zvichiisa hwaro hwakasimba hwekuvandudzwa kwemhando yepamusoro munguva yekugadzira zvinhu zvine hungwaru.
