Ungakhetha njani iintsimbi zokusila ezifanelekileyo ekusileni okumanzi?
Kwinkqubo yokusila emanzi, ukhethoiibhili zokugayainxulumene ngokuthe ngqo nokusebenza kakuhle kokugqiba kokugaya, umgangatho wemveliso kunye nobomi bezixhobo. Nokuba kushishino lokugquma, i-inki, i-electronic paste okanye i-biomedicine, ukukhetha iintsimbi zokugaya ezifanelekileyo kubalulekile. Eli nqaku liza kukunceda ukhethe ngokwesayensi kwii-engile ezahlukeneyo ukuze ufumane iziphumo zokugaya ezifanelekileyo nezizinzileyo.
1. Cacisa injongo yokugaya
Ngaphambi kokukhetha iintsimbi zokusila, kufuneka uqale ucacise injongo ephambili yenkqubo yokusila. Iimfuneko zobukhulu beenxalenye zezinye zezinto ezisisiseko ekufuneka ziqwalaselwe: ukuba imveliso ifuna i-submicron okanye i-nanometer ubukhulu beenxalenye zeentlobo, iintsimbi zokusila ezincinci zeenxalenye zeentlobo zeentlobo ziyafuneka ukuze kubonelelwe ngamandla aneleyo okusila kunye noxinano lwamandla ukuze kufezekiswe ukusebenza kakuhle kokusila. Ukongeza, ubunzima bezinto buya kuchaphazela nokukhetha izinto zeentsimbi. Umzekelo, izinto ezinobunzima obuphezulu ziya kwandisa ukuguguleka kweentsimbi ngexesha lenkqubo yokusila, ngoko ke kudla ngokufuneka ukuba kukhethwe iintsimbi ezinamandla aphezulu kunye nokumelana nokuguguleka okufana nokui-zirconium oxide; Kwizinto ezithambileyo, iiglasi ezibiza kakhulu okanye ii-alumina beads zingakhethwa. Enye into ekufuneka iqwalaselwe kukuthambekela kwemveliso, ngakumbi kwizicelo ezineemfuno eziphezulu zococeko ezifana namayeza, iimveliso zebhayoloji, kunye ne-slurry ze-elektroniki. Ukufuduka kwee-ion zesinyithi okanye ukungcola okulandelelanayo ngexesha lenkqubo yokusila kunokuchaphazela ukusebenza kwemveliso. Kule meko, ii-non-metallic beads ezinongcoliseko oluphantsi kunye nozinzo oluqinileyo lweekhemikhali kufuneka zikhethwe, njenge-high-purity zirconium oxide okanye i-aluminium oxide beads, ukuqinisekisa ukhuseleko lwemveliso kunye nokuhambelana kwayo.
2. Khetha izinto ezisetyenziswa ngamabhondi ngokusekelwe ekuhambelaneni kweekhemikhali kunye nokumelana nokuguguleka
Izinto zokugaya kufuneka zibe nozinzo oluhle lweekhemikhali kunye neempawu zoomatshini. Ezi zilandelayo ziimpawu kunye neemeko zokusetyenziswa kwezinto ezininzi ezisetyenziswa rhoqo:
Iintsimbi ezenziwe ngezinto ezahlukeneyo zineengenelo zazo, ekufuneka ziqwalaselwe ngokupheleleyo xa zidibene neempawu zakho zezinto kunye nokubekwa kwemveliso.
3. Ukukhetha okufanelekileyo kobukhulu beentsimbi kunye nokusasazwa kobukhulu beesuntswana
Ubungakanani kunye nokusasazwa kweiibhili zokugayazinempembelelo enkulu kwisiphumo sokusila:
Ubungakanani besuntswana elincinci (<0.3mm) linendawo enkulu yomphezulu kunye nokuphindaphinda kokungqubana okuphezulu, okufanelekileyo kwiindawo ezilandela ubungakanani besuntswana obuncinci kakhulu;
Ubungakanani besuntswana elikhulu (>0.6mm) linamandla amakhulu okuchukumisa kwaye lifanelekile ekugayweni okuqinileyo okanye ekunyangweni kwangaphambili kwezinto ezinkulu zesuntswana;
Kwezinye iindlela zoshishino, ukusetyenziswa okuxutyiweyo kweentsimbi ezinkulu nezincinci kunokudala imeko-bume yokusila elungelelanisiweyo, nto leyo enceda ekuphuculeni ukusebenza kakuhle kunye nokufana kokusasazwa kobungakanani beenxalenye zemveliso.
Xa isebenza ngokwenene, ulawulo lwesayensi lokusasazwa kobukhulu beentsimbi ludla ngokuba luncedo ngakumbi kunobungakanani besuntswana elinye.
4. Nika ingqalelo kwimpembelelo yoxinano lweentsimbi kubunzulu bokugaywa
Ubuninzi beentsimbi zokugaya buchaza amandla empembelelo kunye nobunzulu bokugaya:
Iibhidi ezinobunzima obuphezulu (>5.5g/cm³) zinamandla amakhulu okuchukumisa, okunceda ukuqhekeza ngokukhawuleza izinto eziqinileyo kwaye zihlala zisetyenziselwa ukugaya izinto ezingaphiliyo kakuhle;
Iibhile ezixineneyo (2.5–4.0g/cm³) zinobunzima obuthambileyo, obufanele izinto ezibuthathaka nezinobushushu, kwaye zinokunciphisa ngempumelelo ubushushu obugqithisileyo kunye nomonakalo osikiweyo ngexesha lokusila.
Ukukhethwa koxinano akuchaphazeli nje kuphela ukusebenza kakuhle, kodwa nokusetyenziswa kwamandla kunye nolawulo lobushushu, kwaye kufuneka kuphuculwe ngokuhambelana nemilinganiselo yezixhobo.
5. Lawula iingozi zongcoliseko
Ulawulo longcoliseko yenye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe xa kusikwa amanzi, ingakumbi kumashishini amayeza, ukutya, kunye ne-elektroniki. Ezinye izinto ezisetyenziswa ngama-bead, njengee-bead zentsimbi kunye nee-ceramics ezingcolileyo, zinokukhupha iintsimbi okanye izinto ezingalindelekanga, nto leyo ebangela ungcoliseko lwemveliso. Ngeli xesha,iiglasi zentsimbi, iibhini ze-zirconia, okanye izixhobo zeseramikhi ezicocekileyo kakhulu kufuneka zinikwe kuqala ukuqinisekisa ukucoceka kwenkqubo.
6. Ukuqwalaselwa ngokubanzi kweendleko kunye nobomi
Ixabiso lezinto ezahlukeneyo zentsimbi liyahluka kakhulu, kwaye ubomi benkonzo kunye neendleko zokugcinwa nazo zahlukile:
Nangona ixabiso lokuqala lokuthenga iintsimbi ezisebenza kakuhle liphezulu, zinobomi obude benkonzo, zinciphisa amaxesha okutshintshwa kwezixhobo kunye nexesha lokungasebenzi, kwaye zibiza kancinci ekuhambeni kwexesha;
Iintsimbi ezixabiso liphantsi zinotyalo-mali oluncinci lokuqala, kodwa ukuba zihlala zitshintshwa okanye zigugiswa lula, iindleko zokusebenza zizonke ziya kunyuka.
Kucetyiswa ukuba kudityaniswe imeko yomgca wemveliso yenkampani, kuhlolwe izinga lokuguguleka kwezinto, ukusetyenziswa kwamandla, kunye notshintsho kwimveliso, kwaye kwenziwe ukhetho olungabizi kakhulu.
7. Ukuqinisekiswa kovavanyo oluncinci kunye nokwenza ngcono iiparameter
Emva kokukhetha izinto ezisetyenziswa xa kugaywa, kuyacetyiswa ukuba kwenziwe uvavanyo oluncinci. Vavanya ukufezekiswa kobukhulu beentwana ekujoliswe kuzo, ixesha lokugaywa, ukuhambelana kwemveliso, kunye nokuba kukho na ezinye iimveliso eziphuma kuzo.
Iziphumo zovavanyo zingasetyenziselwa ukulungisa iiparameter ezibalulekileyo ezifana nesantya sokujikeleza, umlinganiselo wokuzaliswa kweentsimbi, ixesha lokusila, njl. ukuqinisekisa ukuba isiphumo sokugqibela semveliso yobuninzi siyahlangabezana nemigangatho.
Isiphelo: Nangona iintsimbi zokusila zincinci, zimisela ukusebenza kakuhle, umgangatho wemveliso kunye neenzuzo zoqoqosho zokusila okumanzi. Ukukhetha kwenzululwazi kufuneka kuthathele ingqalelo iimfuno ekujoliswe kuzo, iimpawu zezinto eziphathekayo, ukuthelekiswa kwezixhobo kunye nolawulo lweendleko. Ngovavanyo olwaneleyo lwangaphambi kwexesha kunye nokwenza ngcono iiparameter, ukusila okusebenzayo akunakufezekiswa kuphela, kodwa nokuzinza kwemveliso kunye nokukhuphisana kwemveliso kunokuphuculwa kakhulu.
