Njengamanje, izindlela zokukhiqiza ze-calcium carbonate ezisindayo ikakhulukazi zihlanganisa indlela eyomile kanye nendlela emanzi.Indlela eyomile ngokuvamile ikhiqiza i-calcium esindayo enezikhala ezingaphansi kuka-2500.Uma i-calcium esindayo enezikhala ezingaphezu kuka-2500 ikhiqizwa, ukugaya okumanzi kusetshenziswa kakhulu, futhi ukugaya okomile kuyisinyathelo sokuqala sokugaya okumanzi.Ukugaya okumanzi kwe-calcium enzima kunezici zokucubungula kahle uketshezi, ukukhanya okuphezulu kwendawo kanye nezakhiwo ezinhle kakhulu zemishini, futhi isetshenziswa kakhulu emikhiqizweni yepulasitiki;Ngokukhula kokucoleka, isilinganiso sokungafani, ukushaqeka kanye nobumhlophe bopende we-latex osetshenziswa ezindongeni zangaphakathi ziyakhula kancane kancane.Ngakho-ke, abakhiqizi be-calcium abaningi kakhulu baye baqala ukuthuthukisa ukukhiqizwa kwe-calcium esindayo yokugaya kusuka ku-inqubo eyomile umugqa wokukhiqiza i-calcium esindayo.HCMilling(Guilin Hongcheng), njengomkhiqizi we calcium enzimaumshini wokugayaumshini, uzokwethula ukukhiqizwa nokusetshenziswa kwe-calcium esindayo yokugaya emanzi.

1, Ukukhiqizwa kokugaya okumanzi esindayo se-calcium carbonate: okokuqala, ukumiswa kokugaya okomile kwe-calcium powder kufakwacalcium enzimaumshini wokugayaukuze kuqhutshekwe nokuchotshozwa, bese kuthi i-calcium carbonate enzima kakhulu ilungiswe ngemva kokuphelelwa amanzi emzimbeni nokomiswa.Inqubo yokukhiqiza yokugaya i-calcium esindayo emanzi imi kanje:

(1) Insimbi eluhlaza → ukuphuka kwemihlathi → i-calcium carbonate Raymond Mill → umshini wokuxubha omanzi noma umshini wokuhlubula (izikhawu, izigaba eziningi noma umjikelezo) → isigaba esimanzi → ukuhlola → ukomisa → ukwenza kusebenze → izikhwama (izinga elimboziwe le-calcium carbonate).Ukuhlukaniswa kwe-ultrafine okumanzi kwengezwa ekugelezeni kwenqubo, okungahlukanisa ngesikhathi imikhiqizo efanelekayo futhi kuthuthukise ukusebenza kahle.Imishini yokuhlukanisa i-ultrafine emanzi ikakhulukazi ihlanganisa isivunguvungu esinobubanzi obuncane, i-horizontal spiral classifier kanye ne-disc classifier.I-slurry emva kokuhlukaniswa incane kakhulu, futhi ngezinye izikhathi ithangi le-sedimentation liyadingeka.Inqubo inezinkomba ezinhle zezomnotho, kodwa ukuhlukanisa kunzima ukusebenza.Okwamanje, awukho umshini wokuhlukanisa i-ultrafine osebenza kahle kakhulu.

(2) Insimbi eluhlaza → ukuphuka kwemihlathi → i-calcium carbonate Raymond Mill → isigayo esinyakazayo esimanzi → ukuhlola → ukomisa → ukwenza kusebenze → isikhwama (ibanga lokugcwalisa i-calcium esindayo).

(3) Insimbi eluhlaza → ukuphuka kwemihlathi →i-calcium carbonate Raymond Mill → isigayo esinyakazayo esimanzi noma umshini wokuhlubula (izikhawu, izigaba eziningi noma ukujikeleza) → ukuhlola (ibanga lokumboza ngephepha elisindayo nge-calcium).

2, Izinzuzo zokugaya okumanzi i-calcium esindayo: uma kuqhathaniswa ne-calcium eyomile yokugaya, ukugaya okumanzi kwe-calcium kunezinzuzo ezithile ezisobala.Ibonakala kakhulu kulezi zici ezilandelayo:

(1) Usayizi wezinhlayiya: i-calcium esindayo kakhulu ekhiqizwa ukugaya okumanzi inosayizi wezinhlayiya ezincane, ikakhulukazi ikhiqiza imikhiqizo enezinhlayiya ezingaphezu kuka-3000, <2 μ Okuqukethwe ngu-m ngokuvamile kungafinyelela ku-90%, kuyilapho usayizi wokusanhlamvu wemikhiqizo eyomile uma kuqhathaniswa. i-coarse, ikakhulukazi ekhiqiza imikhiqizo engaphansi kuka-2500 mesh.

(2) Ukusatshalaliswa kosayizi wezinhlayiyana: ukusatshalaliswa kosayizi wezinhlayiyana ze-calcium esindayo ekhiqizwa inqubo emanzi kuncane, kunokusabalalisa okukodwa noma okuphindwe kabili;Nokho, ukusatshalaliswa kosayizi wezinhlayiyana ze-calcium esindayo ekhiqizwa indlela eyomile kubanzi uma kuqhathaniswa, futhi kusesimweni seziqongo eziphindwe kabili noma eziningi.

(3) I-Granular: Ngenxa yemvelo ehlukene yokugaya kanye nemodi yokucindezeleka yezinhlayiya ngesikhathi sokugaya, izinhlayiya zemikhiqizo ye-calcium esindayo emanzi ngokuvamile ziyi-spherical noma i-quasi-spherical, kuyilapho imikhiqizo yendlela eyomile ngokuvamile i-amorphous enemiphetho ecacile namakhona.

(4) Umswakama: I-calcium enzima kakhulu emanzi kakhulu iye yadlula inqubo yokomisa ekukhiqizeni, futhi umswakama ngokuvamile ulawulwa ngaphansi kuka-0.3%, kodwa umswakama we-calcium esindayo okhiqizwa indlela eyomile awukwazi ukulawulwa, ngokuvamile ngaphezu kwalokho. 1%.Ngakho-ke, ukuhlakazeka kanye nokumanzi kwe-calcium esindayo esindayo emanzi kakhulu phakathi nenqubo yokuguqulwa ngokusobala kungcono kunaleyo ekhiqizwa indlela eyomile.

3,Faka isicelocalcium enzimaumshini wokugaya ukugaya okumanzi kwe-calcium enzima:

(1) Upende we-emulsion: Lapho i-calcium carbonate isetshenziswa njengesigcwalisi kupende we-latex, idlala indima yokugcwalisa futhi inomsebenzi othile wokumboza owomile, onganciphisi nje kuphela izindleko zopende we-latex, kodwa futhi usebenza njengohlaka lwamathambo, futhi uthuthukisa ukushuba kwefilimu, ubulukhuni, ukumelana namanzi nokumelana nokukhuhla.Ngakho-ke, ukusetshenziswa kwe-calcium esindayo embonini yokuhlanganisa izakhiwo kuyanda.

(2) Ulwelwesi oluvunyelekayo: Ukuhlakazeka kanye nosayizi wezinhlayiyana (usayizi nokusabalalisa) kwe-calcium carbonate powder kunquma uketshezi lwempushana ngokwayo, futhi kuphinde kuthinte ngokuqondile isivinini sokukhiqiza nokuzinza kwenqubo yolwelwesi oluvuvukalayo, olunendima ebalulekile i-tensile porosity, isakhiwo se-pore, ukuvuthwa kanye nezakhiwo zemishini ze-membrane ekwazi ukungena.Ukusetshenziswa kwe-calcium esindayo ekhiqizwa ukugaya okumanzi njenge "porogen" inenani eliphansi lokumuncwa kwamafutha, ukuhlakazeka okungcono kanye ne-fluidity, futhi kunganciphisa kakhulu inani le-resin carrier, plasticizer, lubricant nezinye izithasiselo.

(3) Umbala we-masterbatch: Umbala we-masterbatch wombala uyindlela evame ukusetshenziswa kakhulu ekufakeni umbala wepulasitiki njengamanje, ovame ukwakhiwa ngenhlaka ye-carrier, i-pigment kanye nezithasiselo.Inani elikhulu locwaningo libonise ukuthi ukusebenzisa i-calcium carbonate, i-wollastonite noma i-barium sulfate esikhundleni sombala othile ukulungisa umbala we-masterbatch kungathuthukisa ukusakazeka kwezingulube futhi kunciphise izindleko zokukhiqiza ngaphandle kokunciphisa ukusebenza kombala we-masterbatch yombala.Olunye ucwaningo luye lwabonisa ukuthi i-masterbatch yombala elungiselelwe ngokugaya okumanzi kwe-calcium bicarbonate esikhundleni se-titanium dioxide, lapho inani elishintshayo lingu-20%, ukusebenza kombala kuhlala kungashintshile, futhi ukusebenza kufana kakhulu nalokho kwe-pigment ehlanzekile, kunomehluko omncane wombala.

Njengomkhiqizi we calcium enzimaumshini wokugayaumshini, iI-HCQ, i-HC yochungechunge olukhulu lwe-calcium esindayo uRaymond mill, I-HLM esindayo i-calcium coarse powder eqondileukugayaisigayonokunye calcium enzimaumshini wokugayaimishini ekhiqizwe i-HCMilling(Guilin Hongcheng) isetshenziswe kabanzi futhi yazuza idumela elihle ekukhiqizweni okomile kokugaya okumanzi kwe-calcium esindayo.Uma unesidingo sokukhiqiza sokugaya okumanzi kwe-calcium esindayo futhi udinga okokusebenza komshini wokugaya okomile osekupheleni, sicela uthinte i-HCM ukuze uthole imininingwane yesisetshenziswa.
