Lapho uthenga amapulatifomu anembayo egwadule, ukuqonda umehluko phakathi kwegwadle lemvelo kanye negwadle lokwenziwa kubalulekile ekwenzeni isinqumo unolwazi. Zombili izinto ezisetshenziswayo zisetshenziswa embonini yokulinganisa ukunemba, kodwa zihluka kakhulu ngesakhiwo, ukwakheka, nezici zokusebenza. Ukwazi ukuhlukanisa phakathi kwazo kusiza ukuqinisekisa ukuthi uthola umkhiqizo ofanele wohlelo lwakho lokusebenza.
Igwadle lemvelo luhlobo lwedwala elivuthayo elakheka ekujuleni komhlaba phakathi kwezigidi zeminyaka. Yakhiwa ikakhulukazi i-quartz, i-feldspar, namanye amaminerali ahlangana ngokuqinile, ayinikeze ukuqina okuhle kakhulu nokuzinza kwesikhathi eside. Lesi sakhiwo se-crystalline semvelo sinikeza ukumelana okuvelele ukugqoka, ukugqwala, nokuguqulwa. Izinkundla zegwadle zemvelo—njengalezo ezenziwe ngegwadle elimnyama le-ZHHIMG®—zaziwa ngokuminyana kwazo okuphezulu, ukuthungwa okufanayo, namandla angashintshi emishini. Uma epholishiwe, abonisa isiphetho esibushelelezi, esicwebezelayo esinokuhlukahluka okucashile kokusanhlamvu nombala obonisa imvelaphi yawo yemvelo.
I-Granite yokwenziwa, ngezinye izikhathi ebizwa ngokuthi i-mineral casting noma itshe lokwenziwa, iyinhlanganisela eyenziwe ngumuntu. Ivamise ukwenziwa ngamaqoqo egwadle echotshoziwe ahlanganiswe ne-epoxy resin noma i-polymer. Ingxube ithululelwa esikhunjeni futhi yelashwe ukuze yakhe izingxenye ezinembayo. I-Granite yokwenziwa inikeza izinzuzo ezithile ekusebenzeni okudambisayo kanye nokuguquguquka kokukhiqiza, njengoba ingabunjwa ibe amafomu ayinkimbinkimbi kalula kunetshe lemvelo. Kodwa-ke, izici zayo ezibonakalayo zincike kakhulu esilinganisweni se-resin kanye nekhwalithi yokukhiqiza, futhi ingase ingafinyeleli ubulukhuni obufanayo, ukuqina kokushisa, noma ukugcinwa kokucaba okude kwesikhathi eside njengegwadle lemvelo lekhwalithi ephezulu.
Ukuze uthole indlela elula yokuzihlukanisa, ungathembela ekuhloleni okubonakalayo nasekubukeni okuthintekayo. Igwadle lemvelo linezinhlamvu zamaminerali ezihlukile ezibonakala ngeso, ezinomehluko omncane wemibala kanye nokucwebezela kwekristalu ngaphansi kokukhanya. I-granite yokwenziwa ijwayele ukuba neyunifomu eyengeziwe, ukubukeka kwe-matte okunezinhlamvu ezimbalwa ezibonakalayo ngenxa ye-resin binder. Ukwengeza, uma uchofoza phezulu ngento yensimbi, igwagwagwa lemvelo likhiqiza umsindo ozwakalayo, okhalayo, kuyilapho igwadle lokwenziwa linikeza ithoni efiphele ngenxa yezakhiwo ezidambisayo ze-resin.
Ekusetshenzisweni okunembayo—okufana nemishini yokulinganisa yokuhlanganisa, amapuleti angaphezulu, nezinkundla zokuhlola—igwagwagwa lemvelo lihlala liyinto ethandwayo ngenxa yokuqina nokukhuthazela okuqinisekisiwe. Igwadle yokwenziwa ingafaneleka kwezinye izinhlelo zokusebenza ezidinga ukumuncwa kokudlidliza, kodwa ngokunemba kwesikhathi eside nokuzinza kobukhulu, amapulatifomu egwadule emvelo avame ukuba phezulu.
I-ZHHIMG, enokuhlangenwe nakho kwamashumi eminyaka ekukhiqizeni okunembe kakhulu, isebenzisa kuphela igwadle elimnyama lemvelo elikhethwe ngokucophelela ngezinkundla zayo ezinembayo. Ibhulokhi ngalinye lihlolelwa ukuminyana okufanayo, ukunwebeka okuphansi kokushisa, kanye nemodulus ephezulu yokunwebeka ukuze kuqinisekiswe ukusebenza okukhethekile kwe-metrological nempilo ende yesevisi.
