Parizvino, nzira dzekugadzira heavy calcium carbonate dzinosanganisira nzira yakaoma uye nzira yakanyorova. Nzira yakaoma inowanzo gadzira heavy calcium ine mesh isingasviki 2500. Kana calcium yakawanda ine mesh inopfuura 2500 ikagadzirwa, kukuya kwakanyorova kunonyanya kushandiswa, uye kukuya kwakanyorova ndiyo nhanho yekutanga yekukuya kwakanyorova. Kukuya kwakanyorova calcium ine hunhu hwekunyorova kwakanaka, kupenya kwepamusoro uye hunhu hwakanaka hwemakanika, uye inonyanya kushandiswa muzvigadzirwa zvepurasitiki; Nekuwedzera kwekupfava, chiyero chekuenzanisa, kugezwa uye kuchena kwependi yelatex inoshandiswa pamadziro emukati zvinowedzera zvishoma nezvishoma. Nokudaro, vagadziri vecalcium vakawanda vakatanga kugadzira kugadzirwa kwe heavy calcium kubva kumutsetse wekugadzira calcium inoremaHCMilling (Guilin Hongcheng), semugadziri we karusiyamu yakawandachigayo chekukuyamuchina, uchatanga kugadzirwa nekushandiswa kwecalcium inorema yakanyorova.

1、 Kugadzirwa kwe calcium carbonate inorema yekukuya yakanyorova: kutanga, kusungirirwa kweupfu hwecalcium inorema yekukuya yakaomeswa kunoiswa mukarusiyamu yakawandachigayo chekukuyakuti inyatsopwanywa, uye calcium carbonate inogadzirwa zvakanaka kwazvo mushure mekushaya mvura mumuviri uye kuoma. Maitiro ekugadzira calcium inopwanywa mumvura ndeekuti:

(1) Matombo asina kubikwa → kutyoka shaya → calcium carbonate Raymond chigayo → muchina wekusanganisa wet mixing kana stripping (inopindirana, ine nhanho dzakawanda kana kutenderera) → wet classifier → screening → drying → activation → bagging (yakaputirwa grade heavy calcium carbonate). Wet ultrafine classification inowedzerwa ku process flow, izvo zvinogona kuparadzanisa zvigadzirwa zvakakodzera panguva uye kuvandudza kushanda. Wet ultrafine classification michina inonyanya kusanganisira small dayameter cyclone, horizontal spiral classifier uye disc classifier. Slurry mushure mekupatsanura yakatetepa, uye dzimwe nguva tangi re sedimentation rinodiwa. Maitiro acho ane zviratidzo zvakanaka zvehupfumi, asi kupatsanura kwakaoma kushanda. Parizvino, hapana michina inoshanda zvikuru yekupatsanura wet ultrafine.

(2) Matombo asina kubikwa → kutyora shaya → calcium carbonate Raymond chigayo → Chigayo chekukurunga chakanyoroveswa → kuongorora → kuomesa → kuvhura → kuisa calcium yakawanda mubhegi (filler grade heavy calcium).

(3) Matombo asina kubikwa → kutyora shaya →calcium carbonate Raymond chigayo → muchina wekukurunga wakanyorova kana wekukurunga (unopindirana, une zvikamu zvakawanda kana kutenderera kwemvura) → kuongorora (kufukidza pepa necalcium yakawanda).

2. Mabhenefiti ekukuya calcium inorema: kana tichienzanisa nekukuya kwakaoma calcium inorema, kukuya calcium inorema kune zvakanakira zviri pachena. Zvinonyanya kuratidzwa muzvinhu zvinotevera:

(1) Saizi yezvikamu: calcium yakawanda kwazvo inogadzirwa nekukuya zvine hunyoro ine saizi yezvikamu zvidiki, inonyanya kugadzira zvigadzirwa zvine meshes dzinopfuura 3000, <2 μ Zviri mukati me m zvinowanzo kusvika 90%, nepo saizi yezvikamu zvezvigadzirwa zvakaoma iri hombe, inonyanya kugadzira zvigadzirwa zviri pasi pe2500 mesh.

(2) Kugoverwa kwehukuru hwezvikamu: kugoverwa kwehukuru hwezvikamu zvecalcium inorema inogadzirwa nekunyorova kwakamanikana, nekugoverwa kwechikamu chimwe chete kana kaviri; Zvisinei, kugoverwa kwehukuru hwezvikamu zvecalcium inorema inogadzirwa nenzira yakaoma kwakafara, uye kuri muchimiro chezvikamu zviviri kana zvakawanda.

(3) Granular: Nekuda kwenzvimbo dzakasiyana dzekukuya uye maitiro ekumanikidzwa kwezvikamu panguva yekukuya, zvikamu zvezvigadzirwa zvecalcium zvinorema zvinowanzova zvakaita sedenderedzwa kana kuti denderedzwa, nepo zvigadzirwa zvemhando yakaoma zvisingawanzoonekwi zvine mipendero nemakona zviri pachena.

(4) Hunyoro: Kalisiyumu yakanyorova yakawanda yakapinda mukuita kwekuomesa panguva yekugadzira, uye hunyoro hunowanzo dzorwa pasi pe0.3%, asi hunyoro hwekalisiyumu yakanyorova inogadzirwa nenzira yekuomesa hahugone kudzorwa, kazhinji inopfuura 1%. Saka, kupararira nekuyerera kwekalisiyumu yakanyorova yakawanda panguva yekugadzirisa zviri pachena kuti zviri nani pane izvo zvinogadzirwa nenzira yekuomesa.

3、Isakarusiyamu yakawandachigayo chekukuya kukuya zvine calcium yakawanda:

(1) Pendi yeEmulsion: Kana calcium carbonate ikashandiswa sekuzadza pendi yelatex, inoita basa rekuzadza uye ine mashandiro ekuvhara akaoma, izvo zvisingangoderedzi mutengo wependi yelatex chete, asiwo zvinoshanda semapfupa, uye zvinovandudza ukobvu hwefirimu, kuomarara, kuramba mvura uye kuramba kukwesha. Saka, kushandiswa kwecalcium yakawanda muindasitiri yekupenda zvivakwa kwakawedzera.

(2) Kamudzira kanoyerera: Kupararira uye saizi yezvidimbu (hukuru nekupararira) kweupfu hwecalcium carbonate zvinosarudza kuyerera kweupfu pachahwo, uye zvinokanganisa zvakananga kumhanya kwekugadzirwa uye kugadzikana kwemaitiro ekamudzira kanoyerera, izvo zvine basa guru mukudzika kwehuremu, chimiro cheburi, kuyerera uye hunhu hwemakanika ekamudzira kanoyerera. Kushandiswa kwecalcium yakawanda inogadzirwa nekukuya kwakanyorova se "porogen" kune kukosha kwakaderera kwekunyudzwa kwemafuta, kupararira kuri nani uye kuyerera, uye kunogonawo kuderedza zvakanyanya huwandu hwecarrier resin, plasticizer, lubricant nezvimwe zvinowedzera.

(3) Color masterbatch: Color masterbatch coloring ndiyo nzira inonyanya kushandiswa mukupenda purasitiki pari zvino, iyo inowanzo gadzirwa ne carrier resin, pigment nezvimwe zvinowedzera. Ongororo dzakawanda dzakaratidza kuti kushandisa calcium carbonate, wollastonite kana barium sulfate kutsiva mamwe mapigment kugadzira color masterbatch kunogona kuvandudza kupararira kwepigments uye kuderedza mari yekugadzira pasina kuderedza mashandiro eruvara rwe color masterbatch. Dzimwe ongororo dzakaratidza kuti color masterbatch yakagadzirwa nekunyorova calcium bicarbonate pachinzvimbo che titanium dioxide, kana huwandu hwekutsiva huri 20%, mashandiro eruvara anoramba asina kuchinja, uye mashandiro akafanana neaya epigment chaiyo, nemusiyano mudiki weruvara.

Semugadziri we karusiyamu yakawandachigayo chekukuyamuchina, iyoHCQ, HC nhevedzano yakakura yecalcium inorema Raymond mill, HLM heavy calcium coarse powder yakatwasukakukuyachigayonezvimwe karusiyamu yakawandachigayo chekukuyaMidziyo yakagadzirwa neHCMilling (Guilin Hongcheng) yakashandiswa zvakanyanya uye yakawana mukurumbira wakanaka mukugadzira calcium yakawanda inonyungudika nekunyorova. Kana uchida kugadzira calcium yakawanda uye uchida michina yekukuya yakaoma yekunyorova yekumberi, ndapota taura neHCM kuti uwane rumwe ruzivo nezvemidziyo iyi.
