Ko white corundum powder inowedzera sei hupenyu hwebasa rezvishandiso?
Chii chinonyanya kurwadza pakaomakucheka nokukuyaindasitiri? Haisi kuwedzera kwezvikwereti zvemagetsi kana kuoma kwebasa, asi zvishandiso zvinofa nekukurumidza! Kukuya mavhiri, mabhandi ejecha, matombo emafuta, madhisiki ekukuya… vakomana ava vanorarama nazvo “vachaputsika” mumazuva mashoma, uye vachiatsiva neatsva kwakafanana nekucheka nyama. Kunyanya kana uchigadzira zvinhu zviya zvakaoma zvemabhonzo-simbi isina tsvina, alloys anopisa zvakanyanya, uye simbi yakaoma, maturusi anopera nekukasika zvekuti unokahadzika hupenyu hwako.
Hei, shamwari dzekare, nhasi ngatitaure pamusoro pekuti sei chinhu chidiki ichi chisingatarisike,white corundum powder, razova mushonga wo“kuwedzera upenyu” hwematurusi here? Handisi kuwedzeredza. Kana iwe ukaishandisa nemazvo, hazvishamisi kupeta kaviri hupenyu hwezvishandiso, uye mari yekuchengetera yese imari chaiyo!
Ndichakugadziridza!”–Mashiripiti ekuti “kuzvirodza” kunatsiridza
Fungidzira: chidimbu chezviyo zvinoputika pamusoro pevhiri rekukuyayakagomara, uye kugona kunoderera. Panguva ino, kana mavhiri ekukuya akagoverwa zvakaenzana nechena yakachena corundum powder, ivo vakaita se "reserve team" inovandira.
Kana binder yakanyatsopfekwa pasi pekuita kwesimba rekukuya uye kupisa kwekukwesha, twudiki-hupfu hunova nemukana we "kuratidza misoro" uye kutsiva iwo mahombe akagomara kuti agadzirezve kucheka kwakapinza!
Izvi zvinoderedza zvikuru kukurumidza kwegumbo rose rekukuya riri "pasi rakatsetseka", richibvumira gumbo rekukuya kuti rirambe rakapinza kwenguva yakati, simba rekucheka harina kuora, uye kushandiswa kwekugadzirisa kwakagadzikana. Wekishopu yedu inogaya batch ye-high-simba alloy shafts, vachishandisa ceramic kugaya mavhiri akasanganiswa neW10 micro-powder. Kuenzaniswa nemavhiri akajairwa ekukuya, zvinotora ingangoita 30% rimwe basa kukuya risati rada kuchekwa. Sabhuku vanofara chose.
Kiyi yekushandisa micro-powder kuwedzera hupenyu iri mu "kufananidza" uye "kushandisa"
Micro-powder chinhu chakanaka, asi haisi panacea, uye hachisi chinhu chinogona kushandiswa nekungomwaya zvisina tsarukano. Kana iwe uchida kuti inyatso kutamba mashiripiti ekuwedzera hupenyu, iwe unofanirwa kuterera kune:
Sarudza "mudiwa" akakodzera (chidimbu saizi inoenderana): Saizi yechikamu chemicro powder (Nhamba yeW) inofanirwa kuenderana nekukura kwechikamu cheiyo huru abrasive (yakakora zvimedu)! Kana ikanyanya kukora, kuzadza nekurodza kuchaita kwakashata; kana yakanyanya kunaka, inogona kuputirwa zvachose nebhainda uye "inodzipwa" uye haishande. Mutemo wechigunwe: Yakanakira kuti saizi yehupfu hudiki huve hunosvika 1/5 kusvika 1/3 yehukuru hweiyo huru abrasive. Semuenzaniso, kana ukashandisa 46# coarse particles, zvakanyanya kufanira kuenzanisa W20-W14 micro powder.
Tenzi "dosage" (yekuwedzera ratio): Yakawanda sei micro powder yekuwedzera? Kunyanya kuita kushoma hakuoneki, uye kuwanda kunogona kunge kunopesana, kukanganisa kusimba kwebhainda kana kuita kuti vhiri rekukuya rive rakaoma. Chiyero ichi chinoenderana nezviyedzo uye ruzivo, uye chinowanzo gadziridzwa mukati mechikamu che10% -30% yehuremu hweabrasive. Resin kugaya mavhiri anogona kuwedzerwa 20% -30%, uye ceramic kugaya mavhiri kazhinji 10% -20% inokwana. Usaende kunorema nekuda kwezvinhu zvakasimba!
Sarudza "nhandare yehondo" (maturusi anoshanda):
Consolidated abrasives (mavhiri ekukuya, matombo emafuta, misoro inokuya): Iyi ndiyo nhandare huru yekurwira hupenyu hwe micropowder! Kunyanya akakodzera kukuya mavhiri ane resin bonds uye vitrified bonds. Iyo formula uye yekusanganisa maitiro ndiyo kiyi yekuona kuti iyo micropowder yakaparadzirwa zvakaenzana.
Coated abrasives (mabhandi ejecha, sandpaper): Paunenge uchigadzira mabhandi ejecha uye sandpaper, uchiwedzera diki diki yemicropowder (yakadai se5% -15% yeabrasive yakazara) kune base glue uye yakawandisa-glue inogona kuvandudza zvakanyanya simba rekubata remaabrasive particles, kudzivirira iyo abrasive particles kubva pakudonha kubva nguva isati yakwana, uye zvakare kubatsira anti-kusvika. Inonyanya kushanda pakuita mabhanhire ekukuya mabhanhire.
Kukuya nekupukuta mvura/namira: Shandisa zvakanangawhite corundum micropowderkugadzirira mvura yekukuya kana kukwenenzvera paste yekupedza super. Iwo akanyanya kunaka zvimedu uye yakakwira kuenderana kwemicropowder inogona kuwana yakanyanyisa yunifomu uye yakaderera-yakakuvara nzvimbo, uye chishandiso (kupolisha padhi / vhiri) pachayo inopfeka zvishoma nezvishoma.
