Chii hasha guruva?

Hasha zvinhu dzinoratidzwa mano inoshanda zvokuimba chiito. Avo rubatsiro tisisiri tsvina, batsirai kurwisa kubereka hukawanika yakachena pamusoro nengura uye pendi. Kushandira chaikosha, chokwadi, zviri hasha granules, izvo zvinogona zvitarisiko siyana uye hukuru. Imwe mhando granules akadaro hasha guruva, izvo zvinogona fekitari mavambo kana kuva mugumisiro kierrätys tsvina uye t. D.

General ruzivo pamusoro hasha guruva

Guruva vangava unhu hwakasiyana uye kwakatangira, asi kazhinji kacho ichi chinhu chisingadiwi yemudzimu processing simbi nehuni zvigadzirwa. Kazhinji, asi hasha upfu ukasunungurwa mubishi kuita ngaakuyire uye makorari kushandiswa. Guruva inogona vanowanika uye kubudiswa neimba hukawanika, uye makuru vhoriyamu iri Implementation remapazi mu muindasitiri akamboona. Vacho simbi hasha guruva aumba somugumisiro kuparadzwa huru kurapwa zvinhu. Vazhinji namatongo izvi siya ngaakuyire mavhiri nomuviri chiito pamusoro kubaya pamusoro kubatwa. Kana ichi guruva haisi nguva dzose simbi - kazhinji aibatanidza nziyo kuti zvinosanganisirawo hasha tudonhwe paruware.

zvinhu sezvamunoita

Processing abrasives ainyanya kupesvedzera zvibereko ferrous simbi. Zvingava yemberi pagondobwe muchina maturusi motokari uye zvinoriumba, uyewo zvokuvakisa. Hwaro chero sezvamunoita anoumba munhu neguruva simbi - of Unorudzi 30%. Kazhinji vhoriyamu wechipiri kugutsikana kuti aruminiyamu oxide - alumina, kunyange unhu wayo anogonawo siyana. The yechipiri constituent zvinhu hasha Nezvakakuyiwa zvinosanganisira phosphorus, Arsenic, nickel, manganese, chromium uye zvakafanana. D. Zvakawanda zvinoenderana sei nokushanda pamusoro kuroorana hasha guruva. Zvinoumba dzinounzwa muvhenganiswa kazhinji zvinosanganisira zvinhu scale, nengura uye vakwegura pendi coatings. Chaizvoizvo, kurwisa accretions dzakadaro aiwanzoshandisa unyanzvi hasha kubviswa.

Mhando dzakasiyana-siyana hasha guruva

Kupatsanura pazvikanganiso zvakawanda zvinotaurwa kuzvitsaura kubva hasha inoramba. Munzira dzakawanda vava novimba nzira kushanda kurapwa zvinhu. Somuenzaniso, kana munhu vachikuya midziyo ine kamwene muchimiro denderedzwa, kunoguma guruva anganzi nesilicon. Uyewo netsika kushandiswa sandblasting michina vakange pakutanga kushandiswa yakapwanyika hasha mbeu. Vanogona dzinosiyana kukura uye chimiro, asi dambudziko chinoramba chete - kubviswa pamusoro coatings kana basa kuona kumeso pakati workpiece. The yokupedzisira kubudiswa chigadzirwa ichi nyaya kwaizova simbi hasha guruva, asi nenzira isiriyo chimiro. Zvakakosha kuziva kuti, kusiyana nesilicon yeimwe, kwakadaro guruva inogona kushandiswa nekutambira kushandiswa, uye rinoshandiswa sezvo resimbi upfu kuti kukuya.

zvinoitwa

The parameters uye zvivako zviri aumba guruva pakutsvaga ezvinhu remapazi uye zvakashandiswa. Somuenzaniso, muna muchina-kuvaka emakambani yakabereka michina kuti zvinoda mukuru-zvakarurama Kupedzwa hukawanika kune vaida geometric format. In kugadzira ichi pakati mabhanzi uye yakanyikwa chigadzirwa aumbwa krupnofraktsionnaya guruva ane kukura vanogona dzinosiyana 5 kusvika 10 microns. Kazhinji iri kuwanikwa kwemvura chaizvo rapanzvimbo sezvakarayirwa 20% muna uremu. Avhareji akadai emakambani guruva achine anenge 200 g pa 1 tani kuti zvakaipa simbi rinopfungaira. Kana anowedzera kushandiswa uye scarfing, bhuku hasha tsvina inogona yekudyidzana kuwedzera. Kana achiita azvikuya mabasa vhoriyamu zviduku hasha guruva inoumbwa chiduku chakapatsanurwa hunhu. Kwakadaro seguruva vari ayo dhayamita 0.5-1.5 microns. Asi musafunga kuti kuparadzana zvakanaka nezvimedu ngozi pane guru ndivo. Chekutanga, chikuru chikamu muguruva dzokubudisa hwezvekukurukurirana oparesheni. Chechipiri, sezvo vanachiremba nemaonero, nomucheka guruva riri ngozi kune kufema hurongwa. Zvino zvakafanira kuongorora zvakadzama mubvunzo wokuti nei zvakakodzera hwokubata wakasununguka hurumende ichiisa hasha tsvina panguva kugadzira.

The hasha guruva riri ngozi?

Asina vakarongeka guruva dzokubudisa hurongwa chizvarwa simbi guruva vaizongoguma kutungamirira kuti kufambiswa dzedenga rwekuita nzvimbo. In ezvinhu akadaro kazhinji kuva Occupational zvirwere fitters. zvirwere kwakadaro kungasanganisira pneumoconiosis, huruva bronchitis, asima, uye zvichingodaro. D. Kugadzirwa chirwere angava migumisiro dzose zvemapapu kutsamwa uye hasha nezvimedu kubva kubudiswa maturusi workpieces uye zvinhu chacho. Naizvozvo, zvakakosha kuti pakutanga kuronga hurongwa kuti kuchaita inobudirira kubviswa hasha guruva zvakananga rwekuita zvakatipoteredza. Zvichienderana saizi uye kushanda ezvinhu izvi hurongwa dzinorongwa maererano nenheyo siyana. Izvi zvingava mureza maindasitiri vacuum, chokuita ngaakuyire muchina, uye mumaindasitiri kufefetedza.

kubviswa nzira

Small hasha zvinhu kupatsanurwa nokushandisa kukuya michina zvinhu yemanyorero inounganidzwa uye asunungurwa muna chaiyo kugara. Zviri zvakakwana kufunga nezvenzira kuti uwane sangano guruva. Kazhinji, dambudziko riri kugadziriswa ndege, wettable nemvura. Water chifukidzo akaridza upfu kupinda sump, akashongedzerwa aine firita. Next zvakare vane yakachena mvura unoshambidza zvivi migove pakugadzirisa guruva. Nokuti mukuru kunyatsoshanda kungaita mugero Drain kufefetedza hurongwa ichaita kudzivirira uye chero kuputsanya duku inoramba. Pakuvaka kuwedzera kushandisa kare kutaurwa vacuum kuti hasha muguruva, iyo panguva hurumende ichiisa nezvimedu sucks vari chaiyo mudziyo, kudzivisa unoparadzira. More zvokufambisa gadziriro kurwisa abrasion tsvina kusanganisira kushandisa mhepo kuyerera. Somuenzaniso, muna Pfungwa Rwako anogona vakavhiyiwa ejector, riri kuiswa iri nechepakati separator muviri.

mhedziso

Pfungwa ine hasha nezvimedu chinhu chisingadzivisiki chakajairika, kwete chete muna dzinotsanagura kukuya uye makorari. Kunyange randinenge "mukuyi" nokuveza simbi kunoita kuti paumbwe kwakadaro zvinhu. Hazvina nguva zvichiita kuti pave nehurongwa kuburikidza izvo hasha guruva haingabviswi kwaita. Kunyanya mudzimai ezvinhu, apo mumwe-nguva kugadzira akavhiyiwa kunyanya nokuda ichi kutenga chete Vacuum seisingashandi. Muzviitiko zvakadaro zvakafanira kufunga kutanga pachake kufema kudzivirirwa. Panyaya kuchengetedzwa mukamuri hukawanika, ichava kwete nzvimbo pamberi basa kufukidza navo foil. Uye kwairayirwa kuronga kufefetedza - kanenge nepahwindo padare.
