Njengamanje, izindlela zokukhiqiza i-calcium carbonate esindayo zifaka phakathi indlela eyomile kanye nendlela emanzi. Indlela eyomile ngokuvamile ikhiqiza i-calcium esindayo ene-mesh engaphansi kuka-2500. Uma kukhiqizwa i-calcium esindayo ene-mesh engaphezu kuka-2500, kusetshenziswa kakhulu ukugaya okumanzi, futhi ukugaya okomile kuyisinyathelo sokuqala sokugaya okumanzi. Ukugaya okumanzi i-calcium esindayo inezici zokucubungula kahle, ukukhanya okuphezulu kwendawo kanye nezakhiwo ezinhle kakhulu zemishini, futhi isetshenziswa kakhulu emikhiqizweni yepulasitiki; Ngokukhula kobunono, isilinganiso sokungafani, ukugezwa kanye nobumhlophe bepende le-latex elisetshenziswa ezindongeni zangaphakathi kuyanda kancane kancane. Ngakho-ke, abakhiqizi be-calcium esindayo abaningi sebeqalile ukuthuthukisa ukukhiqizwa kwe-calcium esindayo esindayo evela ku-inqubo eyomile yokucubungula i-calcium esindayo yokukhiqiza. I-HCMilling (Guilin Hongcheng), njengomkhiqizi we i-calcium esindayoumshini wokugayaumshini, uzokwethula ukukhiqizwa nokusetshenziswa kwe-calcium esindayo emanzi.

1、 Ukukhiqizwa kwe-calcium carbonate emanzi egaywayo: okokuqala, ukumiswa kwe-dry grinding heavy calcium powder kufakwai-calcium esindayoumshini wokugayaukuze kuqhutshwe okunye, bese kulungiswa i-calcium carbonate esindayo kakhulu ngemva kokuphelelwa amanzi emzimbeni nokomiswa. Inqubo yokukhiqiza yokugaya i-calcium esindayo imanzi yilena elandelayo:

(1) Itshe eliluhlaza → ukuphuka komhlathi → i-calcium carbonate iRaymond mill → umshini wokuxuba omanzi noma umshini wokukhumula (ongaphazanyiswa, onezigaba eziningi noma ojikeleza) → umshini wokuhlukanisa omanzi → ukuhlolwa → ukomisa → ukusebenza → ukufaka isikhwama (i-calcium carbonate esindayo ehlanganisiwe). Ukuhlukaniswa kwe-Wet ultrafine kwengezwa ekugelezeni kwenqubo, okungahlukanisa imikhiqizo efanelekile ngesikhathi futhi kuthuthukise ukusebenza kahle. Imishini yokuhlukanisa i-Wet ultrafine ikakhulukazi ifaka phakathi i-cyclone encane enobubanzi, i-horizontal spiral classifier kanye ne-disc classifier. I-slurry ngemuva kokuhlukanisa incane kakhulu, futhi ngezinye izikhathi kudingeka ithangi lokuthungwa. Inqubo inezinkomba ezinhle zezomnotho, kodwa ukuhlukaniswa kunzima ukusebenza. Okwamanje, ayikho imishini yokuhlukanisa i-wet ultrafine esebenza kahle kakhulu.

(2) Itshe eliluhlaza → ukuphuka komhlathi → i-calcium carbonate iRaymond mill → Umshini wokuxubha omanzi → ukuhlunga → ukomisa → ukuvuselela → ukufaka isikhwama (i-calcium esindayo yezinga lokugcwalisa).

(3) Itshe eliluhlaza → ukuphuka komhlathi →i-calcium carbonate iRaymond mill → umshini wokugaya omanzi noma umshini wokukhumula (ongaphazanyiswa, onezigaba eziningi noma ojikeleza) → ukuhlolwa (i-calcium slurry eningi ye-coating grade).

2. Izinzuzo zokugaya i-calcium esindayo emanzi: uma kuqhathaniswa nokugaya i-calcium esindayo eyomile, ukugaya i-calcium esindayo emanzi kunezinzuzo ezithile ezisobala. Kubonakala kakhulu kulezi zici ezilandelayo:

(1) Usayizi wezinhlayiya: i-calcium esindayo enhle kakhulu ekhiqizwa ngokugaya okumanzi inosayizi wezinhlayiya ezincane, ikakhulukazi ikhiqiza imikhiqizo enama-meshe angaphezu kuka-3000, <2 μ Okuqukethwe kwe-m ngokuvamile kungafinyelela ku-90%, kuyilapho usayizi wezinhlayiya zemikhiqizo eyomile uqinile, ikakhulukazi ikhiqiza imikhiqizo engaphansi kwama-mesh angu-2500.

(2) Ukusatshalaliswa kosayizi wezinhlayiya: ukusatshalaliswa kosayizi wezinhlayiya ze-calcium esindayo ekhiqizwa yinqubo emanzi kuncane, ngokusatshalaliswa kwesiqongo esisodwa noma esiphindwe kabili; Kodwa-ke, ukusatshalaliswa kosayizi wezinhlayiya ze-calcium esindayo ekhiqizwa ngendlela eyomile kubanzi kakhulu, futhi kusesimweni seziqongo ezimbili noma eziningi.

(3) I-granular: Ngenxa yendawo yokugaya ehlukene kanye nendlela yokucindezeleka kwezinhlayiya ngesikhathi sokugaya, izinhlayiya zokugaya okumanzi imikhiqizo ye-calcium esindayo ngokuvamile ziyindilinga noma ziyindilinga, kuyilapho imikhiqizo yendlela eyomile iningi layo lingenasimo esinemiphetho namakhona asobala.

(4) Umswakama: I-calcium emanzi ethambile kakhulu isidlule enkambisweni yokomisa enkambisweni yokukhiqiza, futhi umswakama ngokuvamile ulawulwa ngaphansi kuka-0.3%, kodwa umswakama we-calcium esindayo okhiqizwa yindlela eyomile awukwazi ukulawulwa, ngokuvamile ungaphezu kuka-1%. Ngakho-ke, ukuhlakazeka kanye nokugeleza kwe-calcium esindayo emanzi ethambile kakhulu ngesikhathi senqubo yokuguqulwa kusobala ukuthi kungcono kunaleyo ekhiqizwa yindlela eyomile.

3、Sebenzisai-calcium esindayoumshini wokugaya ukugaya okumanzi kwe-calcium esindayo:

(1) Upende we-emulsion: Uma i-calcium carbonate isetshenziswa njengokugcwalisa kupende we-latex, idlala indima yokugcwalisa futhi inokusebenza okuthile kokumboza okomile, okungagcini nje ngokunciphisa izindleko zopende we-latex, kodwa futhi kusebenza njengohlaka lwamathambo, futhi kuthuthukisa ukujiya kwefilimu, ubulukhuni, ukumelana namanzi kanye nokumelana nokukhuhla. Ngakho-ke, ukusetshenziswa kwe-calcium esindayo embonini yokumboza izakhiwo kubanzi kakhulu.

(2) Ulwelwesi olungena emanzini: Ukusabalala kanye nosayizi wezinhlayiya (usayizi kanye nokusatshalaliswa) kwempuphu ye-calcium carbonate kunquma ukugeleza kwempuphu uqobo, futhi kuthinta ngqo isivinini sokukhiqiza kanye nokuqina kwenqubo yolwelwesi olungena emanzini, olunendima ebalulekile ekuqineni kwe-porosity, isakhiwo se-pore, ukuvuleka kanye nezakhiwo zemishini zolwelwesi olungena emanzini. Ukusetshenziswa kwe-calcium esindayo ekhiqizwa ukugaya okumanzi njenge-“porogen” kunenani eliphansi lokumuncwa kwamafutha, ukuhlakazeka okungcono kanye nokugeleza kwamanzi, futhi kunganciphisa kakhulu inani le-resin yokuthwala, i-plasticizer, i-lubricant nezinye izithasiselo.

(3) I-masterbatch yombala: Ukufaka umbala we-masterbatch yombala kuyindlela esetshenziswa kakhulu ekufakeni imibala ngepulasitiki okwamanje, evame ukwakhiwa nge-carrier resin, i-pigment kanye nezithasiselo. Ucwaningo oluningi lubonise ukuthi ukusebenzisa i-calcium carbonate, i-wollastonite noma i-barium sulfate ukufaka esikhundleni se-pigment ethile ukulungiselela i-masterbatch yombala kungathuthukisa ukusabalala kwe-pigment futhi kunciphise izindleko zokukhiqiza ngaphandle kokunciphisa ukusebenza kombala we-masterbatch yombala. Ezinye izifundo zibonise ukuthi i-masterbatch yombala elungiselelwe ngokugaya okumanzi i-calcium bicarbonate esikhundleni se-titanium dioxide, lapho inani lokufaka esikhundleni lingu-20%, ukusebenza kokufaka umbala kuhlala kungashintshi, futhi ukusebenza kufana kakhulu nokwe-pigment emsulwa, ngomehluko omncane wombala.

Njengomkhiqizi we i-calcium esindayoumshini wokugayaumshini,I-HCQ, uchungechunge lwe-HC olukhulu lwe-calcium esindayo i-Raymond mill, I-HLM heavy calcium coarse powder eqondileukugayaumshini wokugayakanye nokunye i-calcium esindayoumshini wokugayaimishini ekhiqizwe yi-HCMilling (Guilin Hongcheng) isetshenziswe kabanzi futhi yathola idumela elihle ekukhiqizweni okomile kwangaphambi kokugaya i-calcium esindayo. Uma unesidingo sokukhiqiza sokugaya i-calcium esindayo esindayo futhi udinga imishini yokugaya eyomile yangaphambi kokugaya, sicela uxhumane ne-HCM ukuthola imininingwane yale mishini.
