Nidaaminta waxqabadka shiida ee giraangiraha shiida iyadoo loo marayo granularity isku dhafan ee abrasives

2024-10-14

Shididadu waa hannaan makiinadeed kaas oo giraangiraha wax shiida (GS, sida ku xusan Jaantuska 1) loo isticmaalo si looga saaro agabka xawaare wareeg ah oo gaar ah [1]. giraangiraha wax lagu shiidaa waxa uu ka kooban yahay nabar, wakiilka xidha, buuxinta iyo daldaloolada, iwm. Taas oo, naaxdu ay door ka mid ah goynta gees ah inta lagu guda jiro habka shiidi. Adayga, xoogga, dabeecadaha jaban, joomatari ee abrasive ayaa saameyn weyn ku leh waxqabadka shiididda (awoodda wax lagu shiidayo, hufnaanta dusha sare ee qalabka shaqada, iwm) ee giraangiraha shiida [2, 3].

Sawirka 1Taayirrada shiida caadiga ah oo leh granularity isku dhafan ee abrasives.

Xoogga zirconia alumina (ZA) oo leh granularity F14 ~ F30 ayaa la tijaabiyay. Waxyaalaha abrasive ee F16 ama F30 ee diyaarsan GS waxa loo qaybiyey shan darajo sare ilaa hoose: ultrahigh (UH), sare (H), dhexe (M), hoose (L), iyo aad u hooseeya (EL). Waxaa la ogaaday in Weibull xoogga burburinta F14, F16 iyo F30 ee ZA ay ahaayeen 198.5 MPa, 308.0 MPa iyo 410.6 MPa, siday u kala horreeyaan, taas oo muujinaysa in xoogga ZA koray hoos u dhac ku yimid cabbirka xabagta. Qaabka weyn ee Weibullmwaxay muujisay kala duwanaansho yar oo u dhaxaysa qaybaha la tijaabiyay [4-6]. ThemQiimaha ayaa hoos u dhacay hoos u dhaca xajmiga xajinta, taas oo muujinaysa in kala duwanaanshaha u dhexeeya nabarrada la tijaabiyey ay noqdeen kuwo weyn iyadoo hoos u dhac ku yimid xajinta [7, 8]. Maaddaama cufnaanta cilladaha cirridka ay tahay mid joogto ah, nabarrada yaryar waxay leeyihiin qadar yar oo cillado ah iyo xoog sare, taas oo ka dhigaysa in nabarrada yaryar ay adagtahay in la jebiyo.

Qaabka xidhashada dhammaystiran ee hab-socodka adeegga ku habboon ayaa la sameeyay [9], sida ku cad sawirka 3. Marka la eego xaaladaha ugu habboon, abrasive-ku wuxuu leeyahay heer ka faa'iidaysi sare iyo GS waxay muujisaa waxqabadka shiididda wanaagsan [3]. Marka la eego culeyska culeyska la siiyay iyo xoogga wakiilka xiritaanka, hababka xirashada ugu weyn ayaa laga beddelay xirashada xirashada iyo walaxda yar yar ee F16 ilaa xirashada xirashada iyo soo jiidashada F30 lahaanshaha farqiga u dhexeeya xoogga burburinta [10,11]. Xiritaan la'aantu waxay keentay hoos u dhaca GS iyo is-afaynta ay sababto cirib-tirka ka-soo-baxa waxay gaari kartaa xaalad dheellitiran, sidaas darteed kor u qaadista awoodda wax lagu shiido si weyn [9]. Horumarka dheeraadka ah ee GS, xoogga burburinta nabarrada, xoogga wakiilka ku xiran iyo culeyska shiididda, iyo sidoo kale hababka xirashada ee horumarinta abrasives, waa in la hagaajiyaa oo la xakameeyaa si kor loogu qaado heerka isticmaalka abrasives.

In kasta oo waxqabadka shiida ee GS ay saameyn ku leeyihiin arrimo badan, sida xoogga burburinta abrasive, xoogga wakiilka xidha, culayska shiidi, dabeecadaha goynta abrasive, xaaladaha shiidi, iwm, baaritaannada hababka sharciyeynta granularities isku dhafka ah ee abrasives siin kara tixraac weyn oo ku saabsan design iyo wax soo saarka ee GS.
