Chigadzirwa:corundum yebrown
Kuwanda kwezvikamu: #36
Huwandu: matani matanhatu
Nyika: Marazhiya
Kushandiswa: Kuputira jecha remudhudhudhu
Munyika yemidhudhudhu, uko kushanda kwayo kwenguva refu uye kugara kwenguva refu kuri chinhu chakakosha, kugara kwenguva refu kwechikamu chimwe nechimwe kunokosha. Pakati peizvi, cheni yemidhudhudhu inoita basa guru mukutumira simba kubva kuinjini kuenda kumavhiri. Kuti ive nechokwadi chekuti inogara kwenguva refu uye kushanda kwayo zvakanaka, kugadzirisa kwayo kwakakosha. Chimwe chinhu chakakosha pakugadzirisa ndeyekuchenesa nekugadzirisa cheni nguva dzose, uye nzira inoshanda zvikuru yekuita izvi ndeyekuputira jecha. MuMalaysia, vanofarira midhudhudhu nenyanzvi dzekugadzirisa vari kutendeukira kubrown fused alumina grit #36yekuputika kwejecha, zvichichinja nzira inodzoserwa nayo cheni.
Alumina yakasanganiswa nebrown, chinhu chakasimba uye chinokwesha chinobva mubauxite yemhando yepamusoro, chinoratidza kuva sarudzo yakanaka kwazvo yekuputika kwejecha remudhudhudhu. Nekuoma kwayo uye kugara kwenguva refu, inobvisa ngura, tsvina, nezvimwe zvinosvibisa pamusoro pecheni, ichiidzorera pakuva yakachena. Saizi yegrit #36 inoratidza kuenzana kwakakwana pakati pehukasha uye kunyatsoita basa, ichivimbisa kucheneswa kwakakwana pasina kukonzera kukuvara kwecheni.
Kuputira jecha ne brown fused alumina #36 grit kune zvakanakira zvakawanda pane nzira dzechinyakare dzekuchenesa. Chekutanga, kunobvisa kudiwa kwemakemikari akasimba, kunoderedza kukanganisa nharaunda uye kukurudzira maitiro ekuchengetedza asingakuvadzi nharaunda. Chechipiri, kunoderedza zvakanyanya nguva yekushanda, sezvo kushanda kwe grit ye alumina kunobvisa zvinobudirira matanda akaomarara munguva shoma inodiwa nenzira dzekuchenesa nemaoko. Uyezve, kugara zvakanaka uye kunyatsoita zvakanaka kwe sandwich blasting kunoita kuti cheni yese icheneswe zvakaenzana, pasina kusiya nzvimbo isina kubatwa.
Kune vanofarira midhudhudhu kuMalaysia, uko mamiriro ekunze ane hunyoro uye kushandiswa nguva nenguva kunogona kukurumidzisa kuora kwecheni, kushandisa brown fused alumina #36 grit sandblasting senzira yekugadzirisa nguva dzose kunochinja zvinhu. Hazvingowedzere hupenyu hwecheni chete, asiwo zvinowedzera kushanda kwayo uye kuvimbika, zvichibatsira kuti ifambire zvakanaka uye zvakachengeteka.
Mukupedzisa,alumina yakasanganiswa yebrown #36 grit sandblastinginobuda semhinduro inoshanda zvikuru yekugadzirisa cheni dzemidhudhudhu muMalaysia. Simba rayo rekukwesha, pamwe nekunyatsorongeka uye kushanda zvakanaka, rinoita kuti ive sarudzo inonyanya kufarirwa yekuona kuti cheni dzemidhudhudhu dzinogara kwenguva refu uye kushanda zvakanaka munzvimbo dzinopisa dzeMalaysia. Nekugamuchira nzira iyi itsva yekugadzirisa, vatasvi vanogona kunakidzwa nehupenyu hwakareba hwecheni uye kushanda zvakanaka, vachivimbisa makiromita akawanda ezviitiko zvinonakidza mumugwagwa.
