Ngaba ukuguquka kobushushu besiseko sesinyithi esityhidiweyo kubangela ukuphambuka kokuwelda? Ukutyhila iSkimu seMbuyekezo yoBushushu sePlatform yokuWelda yeSolar yeZHHIMG Granite Base.

Kwimveliso yeephaneli zelanga, ukuchaneka kokuwelda kuchaphazela ngqo umgangatho wemveliso. Isiseko sesinyithi esiqhelekileyo, ngenxa yokwanda kobushushu obuphezulu (malunga ne-12×10⁻⁶/℃), sinokuguquguquka xa kushushu kakhulu ukuwelda kunye nokuguquguquka kobushushu bendalo. Xa isiseko sesinyithi esi-1-meter ubude sishushu nge-10℃, sinokwandiswa nge-120μm, nto leyo ebangela ukuba indawo yokuwelda itshintshe, nto leyo echaphazela ukusebenza kunye nobomi bephaneli yelanga, kwaye ikwanyusa iindleko zokugcinwa ngenxa yoxinzelelo.

Isiseko segranite se-ZHHIMG sibonakala kakuhle ngenxa yeenzuzo zaso zendalo. I-coefficient yayo yokwandiswa kobushushu yi-(4-8) × 10⁻⁶/℃ kuphela, ngaphantsi kwesiqingatha sesinyithi esityhidiweyo, kwaye inozinzo oluqinileyo xa ubushushu butshintsha. Ubunzima bufikelela kwi-6-7 kwisikali se-Mohs, bukwazi ukumelana noxinzelelo olunzima kunye namandla empembelelo yezixhobo zokuwelda. Ukusebenza kakuhle kokudambisa kunokufunxa ukungcangcazela, kudala imeko-bume ezinzileyo yokuwelda ngokuchanekileyo.

Ngenxa yesi sizathu, i-algorithm ye-ZHHIMG yokuhlawula ubushushu iphucula ngakumbi ukuchaneka kokuwelda:

Ukubeka esweni ngexesha langempela: Izinzwa zobushushu ezichanekileyo kakhulu zisasazwa kwiindawo ezibalulekileyo zesiseko ukuze ziqokelele idatha yobushushu ngexesha langempela (ngokuchaneka kwe-0.1℃), kwaye intsimi yobushushu yesiseko ihlalutywa ngokupheleleyo ngedatha yamanqaku amaninzi.
Uyilo oluchanekileyo: Ngokusekelwe kulwazi oluninzi lovavanyo, oludityaniswe nezinto ezifana ne-thermal expansion coefficient yegranite kunye nokuma kunye nobukhulu besiseko, imodeli yoguquko lobushushu imiselwe ukuqikelela uguquko kuzo zonke iindlela kumaqondo obushushu ahlukeneyo.
Imbuyekezo eguqukayo: Inkqubo ilungisa indlela yokuhamba kwezixhobo zokuwelda ngexesha langempela ngokusekelwe kwinguquko ebaliweyo. Ukuba inguquko ΔX kwicala le-X ifunyenwe, ingalo yomatshini ihamba kwicala elichaseneyo yi-ΔX ukuze ilwe nempembelelo yenguquko yobushushu.
Ukulungiswa okukrelekrele: I-algorithm ingenza ngcono imodeli kunye neeparamitha zembuyekezo ngokuzenzekelayo ngokusekelwe kwinkqubo yokuwelda, ubushushu obungqongileyo, kunye nobomi benkonzo yesiseko, igcina ukuchaneka okuphezulu rhoqo.

Kwizicelo ezisebenzayo, emva kokuba ishishini elithile lizise iqonga le-granite le-ZHHIMG, izinga leziphene zeemveliso zalo lehle ukusuka kwi-10% ukuya kwi-3%, kwaye ukusebenza kakuhle kwemveliso kwanda ngama-30%.
