Parizvino, nzira dzekugadzira heavy calcium carbonate dzinonyanya kusanganisira nzira yakaoma uye nzira yekunyorova.Iyo yakaoma nzira inowanzo gadzira inorema calcium ine isingasviki 2500 mesh.Kana iyo inorema calcium ine zvinopfuura 2500 mesh inogadzirwa, kunyorova kunoshandiswa kunonyanya kushandiswa, uye kugaya kwakaoma ndiyo danho rekutanga rekunyorova.Kunyorova kukuya heavy calcium ine maitiro ekugadzirisa zvakanaka fluidity, kupenya kwepamusoro kwepamusoro uye yakanakisa mechanical properties, uye inonyanya kushandiswa muzvigadzirwa zvepurasitiki;Nekuwedzera kwekunaka, muyero wekusiyanisa, washability uye kuchena kwepende yelatex yakaiswa kumadziro emukati zvishoma nezvishoma inowedzera.Nokudaro, vanogadzira calcium yakawanda uye inorema vakatanga kugadzira kugadzirwa kwekunyorova kunorema calcium kubva kuneyakaoma nzira inorema calcium processing mutsara wekugadzira.HCMilling(Guilin Hongcheng), semugadziri we calcium yakawandakugayamuchina, uchasuma kugadzirwa uye kushandiswa kwemvura yekukuya inorema calcium.

1, Kugadzirwa kwekunyorova kukuya kunorema calcium carbonate: kutanga, kumiswa kwekuoma kwekukuya inorema calcium poda inoiswa mucalcium yakawandakugayakuti uwedzere kupwanya, uye ipapo iyo yekupedzisira-yakanaka inorema calcium carbonate inogadzirwa mushure mekupera mvura uye kuomeswa.Iyo nzira yekugadzira yekunyorova kugaya heavy calcium ndeyekutevera:

(1) Chicherwa → kutsemuka shaya → calcium carbonate Raymond chigayo → nyoro yekusanganisa chigayo kana yekubvisa muchina (inopindirana, yakawanda-nhanho kana kutenderera) → yakanyorova classifier → kuongorora → kuomesa → activation → bhegi (yakavharidzirwa giredhi rinorema calcium carbonate).Wet ultrafine classification inowedzerwa kune maitiro ekuyerera, ayo anogona panguva yakakodzera kuparadzanisa zvigadzirwa zvinokodzera uye kugadzirisa kushanda zvakanaka.Wet ultrafine classification michina inonyanya kusanganisira diki dhayamita dutu, horizontal spiral classifier uye disc classifier.Iyo slurry mushure mekugadzika ishoma, uye dzimwe nguva sedimentation tank inodiwa.Iyo nzira ine zviratidzo zvakanaka zvehupfumi, asi kupatsanura kwakaoma kushanda.Parizvino, hapana inoshanda zvakanyanya wet ultrafine classification michina.

(2) Chicherwa mbishi → kutyoka shaya → calcium carbonate Raymond chigayo → nyoro inokurunga chigayo → kuongorora → kuomesa → activation → mabhegi (giredhi rekuzadza rinorema calcium).

(3) Chicherwa mbishi → kutyoka shaya →calcium carbonate Raymond chigayo → nyoro inokurunga chigayo kana yekubvisa muchina (inopindirana, yakawanda-nhanho kana kutenderera) → kuongorora (bepa rekuputira giredhi rinorema calcium slurry).

2、 Zvakanakira kunyorova kukuya inorema calcium: zvichienzaniswa nekuoma kukuya inorema calcium, kunyorova kukuya heavy calcium kune zvimwe zviri pachena zvakanakira.Zvinonyanya kuratidzwa muzvikamu zvinotevera:

(1) Particle size: iyo superfine heavy calcium inogadzirwa nekunyorova inogadzirwa neyakaomarara saizi, kunyanya kugadzira zvigadzirwa zvinodarika 3000 meshes, <2 μ Zviri mukati mem zvinokwanisa kusvika 90%, ukuwo saizi yezviyo yakaoma zvishoma. coarse, kunyanya kugadzira zvigadzirwa pazasi 2500 mesh.

(2) Particle size distribution: the particle size distribution ye heavy calcium inogadzirwa nekunyorova process idiki, ine single or double peak distribution;Nekudaro, iyo particle size kugoverwa kweinorema calcium inogadzirwa nenzira yakaoma yakapamhama, uye iri muchimiro chepamusoro pepamusoro kana akawanda.

(3) Granular: Nekuda kwekusiyana kwenzvimbo yekukuya uye kushushikana kwezvimedu panguva yekukuya, zvimedu zvekunyorova zvinorema zvinorema calcium zvigadzirwa zvinowanzoita spherical kana quasi-spherical, nepo yakaoma nzira zvigadzirwa zvinowanzo amorphous zvine micheto uye makona.

(4) Hunyoro: Iyo yakanyorova yepamusoro inorema calcium yakapfuura nekuomesa mukugadzira, uye hunyoro hunowanzodzorwa pazasi 0.3%, asi hunyoro hweiyo inorema calcium inogadzirwa nenzira yakaoma haigone kudzorwa, kazhinji kupfuura. 1%.Naizvozvo, kupararira uye kuyerera kweiyo yakanyorova superfine inorema calcium panguva yekuchinja maitiro zviri pachena zviri nani pane izvo zvinogadzirwa nenzira yakaoma.

3,Shandisa iyocalcium yakawandakugaya kunyorova kukuya kweheavy calcium:

(1) Emulsion pendi: Kana calcium carbonate inoshandiswa sekuzadza mupende ye latex, inoita basa rekuzadza uye ine imwe yakaoma yekuvhara kushanda, iyo isingangodzikisi mutengo wependi ye latex, asiwo inoita seskeleton, uye inovandudza firimu ukobvu, kuoma, kuramba mvura uye kukwesha kuramba.Naizvozvo, kushandiswa kwekarusiyamu inorema muindasitiri yekuputira yekuvaka inowedzera uye yakawedzera.

(2) Membrane inogoneka: Kupararira uye saizi yechikamu (saizi uye kugoverwa) kwecalcium carbonate poda inotaridza kuyerera kwehupfu pachayo, uye zvakare inokanganisa zvakananga kukurumidza kwekugadzira uye kugadzikana kwemaitiro eiyo permeable membrane, ine basa rakasimba mu tensile porosity, pore chimiro, permeability uye michina zvimiro zvepermeable membrane.Kushandiswa kwekarusiyamu inorema inogadzirwa nekunyorova kukuya se "porogen" ine yakaderera mafuta absorption kukosha, nani kupararira uye fluidity, uye inogona zvakare kuderedza zvakanyanya kuwanda kweanotakura resin, plasticizer, lubricant uye zvimwe zvinowedzera.

(3) Colour masterbatch: Ruvara masterbatch coloring ndiyo inonyanya kushandiswa nzira mupurasitiki coloring parizvino, iyo inowanzo umbwa neanotakura resin, pigment uye additives.Nhamba huru yezvidzidzo zvakaratidza kuti kushandisa calcium carbonate, wollastonite kana barium sulfate kutsiva mamwe pigment kugadzirira ruvara masterbatch kunogona kuvandudza kupararira kwe pigment uye kuderedza mari yekugadzira pasina kuderedza kushanda kwemavara evara masterbatch.Zvimwe zvidzidzo zvakaratidza kuti ruvara masterbatch yakagadzirwa nekunyorova ichikuya calcium bicarbonate pachinzvimbo chetitanium dioxide, kana iyo inotsiva huwandu huri 20%, kuita kwemavara kunoramba kusingachinjiki, uye kuita kwakafanana nekwepigment yakachena, ine musiyano mudiki weruvara.

Semugadziri we calcium yakawandakugayamuchina, iwoHCQ, HC yakatevedzana hombe inorema calcium Raymond chigayo, HLM inorema calcium coarse poda yakatwasukakugayachigayonezvimwe calcium yakawandakugayamidziyo inogadzirwa neHCMilling(Guilin Hongcheng) yakashandiswa zvakanyanya uye yakahwina mukurumbira wakanaka kumberi-kumagumo kugadzirwa kwakaoma kwekunyorova kukuya inorema calcium.Kana uine chido chekugadzirwa kwekunyorova kwekarusiyamu inorema uye uchida kumberi-kumagumo kwakaoma kugaya mill, ndapota taura neHCM kuti uwane ruzivo rwemidziyo.
