Kungakhathaliseki ukuthi ukukhetha izingoma zanamuhla ze-plaster, ukufuna njalo abathengi basebenzise ama-plaster ngokusekelwe ezingxenyeni zemvelo. Isibonelo yi-plaster yamaminerali esekelwe ingxube yesinamende noma i-seth-lime. Ngaphezu kwalokho, i-plaster yamaminerali okuhlobisa isetshenziselwa ngempumelelo ukuhlobisa kwangaphandle nezakhiwo zangaphakathi nezakhiwo. Ukuhlobisa kwendawo ephathwayo kutholakala ngenxa yezingxube ezihlukahlukene ekubunjweni kwenhlanganisela ye-mineral plaster, enquma igama negama layo noma uhlobo lwendawo.
Izinhlobo zokugaya amaminerali okuhlobisa
Elinye lama-plasters ahlotshisiwe kakhulu okuhlobisa amaminerali - igobble. Igama layo lingenxa yobukhona ekubunjweni kwamagatsha okuhlwanyela kahle (okusanhlamvu). Uma kusetshenziswe phezulu, isembatho ("ijazi") nesakhiwo esibucayi siyadalwa. Ubukhulu besisindo buxhomeke kubukhulu be-inclusions - amachashaza. Lesi sici (ubukhulu beqhezu le-inclusions) siboniswa ngokucacile emaphaketheni yalesi sakhiwo sokuqeda. Ukugaya amaminerali okuhlobisa okusetshenziswe ngamatshe kungasetshenziselwa imisebenzi yokuqeda ngaphakathi nangaphandle, kunemingcele ephezulu yokusebenza (ukushaqeka, ukuqhuma umoya, ukumelana nemithonya yangaphandle kanye nezinguquko zokushisa).
I- plaster yokuhlobisa amaminerali "ibhungane le-bark" ayithandwa kakhulu futhi inezimfanelo zokusebenza ezifanayo. Umehluko walo ovela ku- plaster yamatshe awukuthi endaweni ephathwayo (ngokufaka ingxube yamatshe noma amatshe e-marble), "isambatho sombobo" sidalwa ngemifula, njengokungathi idliwa yi-beetle. Kumele futhi kuqaphele ukuthi zonke izinhlobo ze-plaster zokuhlobisa amaminerali, kufaka phakathi isicabha, ukunikeza ukuhlobisa okuningi kalula ziboleke ekudwebeni.
