Gutera umucanga

Gutera umucanga: Gutera umucanga bikunze gukoreshwa mu nganda za valve nabyo birashobora kugabanywamo ubwoko butandukanye bwumucanga nkaumucanga utose, umucanga wumye, ikirahuri cyamazi umucanga na furan resin nta-guteka umucangaukurikije binders zitandukanye.

(1) Umusenyi wicyatsi nuburyo bwo kubumba aho bentonite ikoreshwa nkumuhuza mubikorwa. Ibiranga ni: ifu yumucanga yarangiye ntigomba gukama cyangwa kuvurwa bidasanzwe, ifu yumucanga ifite imbaraga zitose, kandi umusenyi hamwe nigikonoshwa bifite inyungu nziza, byoroshye gutera isuku no kugwa kumusenyi. Gukora ibicuruzwa biva mu mahanga ni byinshi, uruziga rukora ni rugufi, kandi ikiguzi cyibikoresho nacyo ni gito, bikaba byoroshye gutunganya umurongo wo guteranya. Ibibi byayo ni: gutera akabariro bikunze kwibasirwa nudusimba, imyanda, umucanga, hamwe numucanga ufatika, kandi ubwiza bwa casting, cyane cyane ubwiza bwimbere, ntiburi kure bihagije.

(2) Umucanga wumye nuburyo bwo kwerekana icyitegererezo ukoresheje ibumba, kandi bentonite nkeya irashobora kunoza imbaraga zayo. Ibiranga ni: ifu yumucanga igomba gukama, ikagira umwuka mwiza no gukwirakwiza ikirere, ntabwo byoroshye kubyara inenge nko gukaraba umucanga, gufatira umucanga, hamwe nu byobo, kandi ubwiza bwimbere muri casting nabwo ni bwiza. Ibibi byayo ni: ibikoresho byo kumisha umucanga birakenewe, kandi umusaruro wigihe kirekire.

(3) Sodium silicike umucanga nuburyo bwo kubumba ukoresheje ikirahuri cyamazi nka binder. Ibiranga ni: ikirahuri cyamazi gifite imikorere yo kuba ishobora gukomera mu buryo bwikora nyuma yo guhura na CO2, kandi irashobora kugira inyungu ninyungu zitandukanye zo kwerekana gaze no kwerekana imiterere. Nubwo bimeze bityo ariko, hari ibibi nko kugwa nabi kw'igikonoshwa, ingorane zo gusukura umucanga kubutaka, hamwe nigipimo gito cyo gutunganya umucanga wakoreshejwe.

. Ku bushyuhe bwicyumba, umucanga ubumba urakira bitewe nubushakashatsi bwimiti ya binder ikorwa numukozi ukiza. Ibiranga ni: ifu yumucanga ntikeneye gukama, igabanya cyane uruzinduko rwumusaruro kandi ikiza ingufu. Umusenyi wububiko bwa resin biroroshye kubyoroshya kandi bifite gusenyuka neza, kandi umusenyi wibumba wa casting nawo urashobora gusukurwa byoroshye, uburinganire bwukuri bwa casting buri hejuru, kandi kurangiza hejuru ni byiza, bishobora kuzamura cyane ubwiza bwa casting. Ibibi byayo ni: ibisabwa byujuje ubuziranenge ku mucanga mbisi nabyo ni byinshi, ahakorerwa ibicuruzwa bifite impumuro nkeya, kandi ibiciro bya resin nabyo ni byinshi. Kuvanga inzira ya furan resin yikomye cyane: Umusenyi wikomye wumucanga ukorwa nibyiza bivangwa numucanga uhoraho, ukongeramo umucanga mbisi, resin, imiti ikiza, nibindi, hanyuma ukabivanga vuba. Kuvanga no gukoresha igihe icyo aricyo cyose. Gahunda yo kongeramo ibikoresho bitandukanye mugihe cyo kuvanga umucanga wa resin nuburyo bukurikira: umusenyi wumwimerere + umuti ukiza (p-toluenesulfonic acide aqueous solution) - (120-180S) - resin + silane - (60-90S) - umucanga (5) Ibisanzwe ubwoko bwumucanga Gukora umusaruro: guta neza.
