Okwangoku, iindlela zokuvelisa i-calcium carbonate enzima ziquka indlela eyomileyo kunye nendlela emanzi. Indlela eyomileyo ngokubanzi ivelisa i-calcium enzima ene-mesh engaphantsi kwama-2500. Ukuba i-calcium enzima ene-mesh engaphezu kwama-2500 iveliswa, kusetyenziswa kakhulu ukugaya okumanzi, kwaye ukugaya okomileyo linyathelo lokuqala lokugaya okumanzi. Ukugaya okumanzi i-calcium enzima ineempawu zokunyibilika kakuhle kokucubungula, ukukhanya okuphezulu komphezulu kunye neempawu ezintle zoomatshini, kwaye isetyenziswa kakhulu kwiimveliso zeplastiki; Ngokunyuka kobuncinci, umlinganiselo wokungafani, ukuhlanjwa kunye nobumhlophe bepeyinti ye-latex esetyenziswa kwiindonga zangaphakathi kuyakhula kancinci kancinci. Ke ngoko, abavelisi be-calcium abaninzi ngakumbi baye baqala ukuphuhlisa imveliso yokugaya okumanzi i-calcium enzima evela kwi-umgca wemveliso yenkqubo eyomileyo yokucubungula i-calcium enzima. I-HCMilling (uGuilin Hongcheng), njengomvelisi we i-calcium enzimaumsi wokugayaumatshini, uza kwazisa ukuveliswa nokusetyenziswa kwe-calcium enzima yokusila emanzi.

1, Ukuveliswa kwe-calcium carbonate emanzi egayiweyo: okokuqala, ukumiswa kwe-calcium powder egayiweyo eyomileyo kufakwa kwi-i-calcium enzimaumsi wokugayaukuze kutyunyuzwe ngakumbi, emva koko kulungiswe i-calcium carbonate enzima kakhulu emva kokuphelelwa ngamanzi emzimbeni kunye nokomiswa. Inkqubo yokuvelisa i-calcium enzima emanzi yile ilandelayo:

(1) Isinyithi esiluhlaza → Ukuqhekeka komhlathi → i-calcium carbonate iRaymond mill → Umatshini wokuxuba omanzi okanye wokukrazula (ongenaziphene, onamabakala amaninzi okanye ojikeleza) → umhleli omanzi → ukuvavanya → ukomisa → ukusebenza → ukubopha (ikhabhoni enzima yecalcium carbonate egqunywe nge-coated grade). Udidi lwe-Wet ultrafine longezwa kuhambo lwenkqubo, olunokwahlula iimveliso ezifanelekileyo ngexesha elifanelekileyo kwaye luphucule ukusebenza kakuhle. Izixhobo zokwahlulahlula ezimanzi ziquka ikakhulu i-cyclone encinci enobubanzi, i-horizontal spiral classifier kunye ne-disc classifier. I-slurry emva kokwahlulahlula incinci, kwaye ngamanye amaxesha kufuneka itanki ye-sedimentation. Inkqubo inezalathisi ezilungileyo zoqoqosho, kodwa ukwahlulahlula kunzima ukusebenza. Okwangoku, akukho zixhobo zokwahlulahlula ezimanzi ezimanzi ezisebenza kakuhle kakhulu.

(2) Isinyithi esiluhlaza → Ukuqhekeka komhlathi → i-calcium carbonate iRaymond mill → Umatshini wokuxovula omanzi → ukucoca → ukomisa → ukusebenza → ukufaka ingxowa (i-calcium enzima yenqanaba lokuzalisa).

(3) Isinyithi esiluhlaza → Ukuqhekeka komhlathi →i-calcium carbonate iRaymond mill → Umatshini wokuxukuxa omanzi okanye wokuhluza (ongenaziphelo, oneenqanaba ezininzi okanye ojikeleza umbane) → Uvavanyo (umxube we-calcium onzima osebenzisa i-paper coating grade).

2. Iingenelo zokusila i-calcium enzima emanzi: xa kuthelekiswa nokusila i-calcium enzima emanzi, ukusila i-calcium enzima emanzi kuneengenelo ezithile ezicacileyo. Oku kubonakala kakhulu kwezi zinto zilandelayo:

(1) Ubungakanani bamasuntswana: i-calcium enzima kakhulu eveliswa kukugaywa okumanzi inobukhulu obuncinci bamasuntswana, ikakhulu ivelisa iimveliso ezinee-meshes ezingaphezu kwama-3000,<2 μ Umxholo we-m ngokubanzi unokufikelela kwi-90%, ngelixa ubungakanani bengqolowa yeemveliso ezomileyo burhabaxa, ikakhulu ivelisa iimveliso ezingaphantsi kwe-2500 mesh.

(2) Ukusasazwa kobungakanani bamasuntswana: ukusasazwa kobungakanani bamasuntswana ekhalsiyam enzima eveliswa yinkqubo emanzi kuncinci, ngokusasazwa kwencochoyi enye okanye ephindwe kabini; Nangona kunjalo, ukusasazwa kobungakanani bamasuntswana ekhalsiyam enzima eveliswa yindlela eyomileyo kubanzi kakhulu, kwaye kukwimo yeencochoyi ezimbini okanye ezininzi.

(3) I-Granular: Ngenxa yemeko-bume yokusila eyahlukileyo kunye nendlela yoxinzelelo lwee-particles ngexesha lokusila, ii-particles ze-wet grinding products ze-calcium ezinzima zihlala zingqukuva okanye zingqukuva, ngelixa iimveliso ze-dry method zingenasimo se-amorphous kunye nemiphetho kunye neekona ezicacileyo.

(4) Ukufuma: I-calcium emanzi ethambileyo kakhulu idlule kwinkqubo yokomisa kwinkqubo yokuvelisa, kwaye ukufuma ngokubanzi kulawulwa ngaphantsi kwe-0.3%, kodwa ukufuma kwe-calcium enzima eveliswa yindlela eyomileyo akunakulawulwa, ngokubanzi ngaphezulu kwe-1%. Ke ngoko, ukusasazeka kunye nokugeleza kwe-calcium emanzi ethambileyo kakhulu ngexesha lenkqubo yokuguqula ngokucacileyo kungcono kunezo ziveliswa yindlela eyomileyo.

3、Faka isiceloi-calcium enzimaumsi wokugaya ukugaywa okumanzi kwe-calcium enzima:

(1) Ipeyinti ye-emulsion: Xa i-calcium carbonate isetyenziswa njengesizalisi kwipeyinti ye-latex, idlala indima yokuzalisa kwaye inokusebenza okuthile kokugquma okomileyo, okunganciphisi nje kuphela ixabiso lepeyinti ye-latex, kodwa kusebenza njengomqolo, kwaye kuphucula ubukhulu befilimu, ubulukhuni, ukumelana namanzi kunye nokumelana nokukhuhla. Ke ngoko, ukusetyenziswa kwe-calcium eninzi kushishino lokugquma izakhiwo kubanzi ngakumbi nangakumbi.

(2) I-membrane ekwaziyo ukugqobhoza: Ukusasazeka kunye nobukhulu beesuntswana (ubukhulu kunye nokusasazwa) kwe-calcium carbonate powder kumisela ukutyibilika kwepowder ngokwayo, kwaye kuchaphazela ngokuthe ngqo isantya semveliso kunye nokuzinza kwenkqubo ye-membrane ekwaziyo ukugqobhoza, enendima ebalulekileyo kwi-tensile porosity, ulwakhiwo lwe-pore, ukugqobhoza kunye neepropati zoomatshini ze-membrane ekwaziyo ukugqobhoza. Ukusetyenziswa kwe-calcium enzima eveliswa kukugaywa okumanzi njenge-"porogen" kunexabiso eliphantsi lokufunxwa kweoyile, ukusasazeka okungcono kunye nokugobhoza, kwaye kunokunciphisa kakhulu ubungakanani be-carrier resin, i-plasticizer, i-lubricant kunye nezinye izongezo.

(3) I-masterbatch yombala: Umbala we-masterbatch yombala yeyona ndlela isetyenziswa kakhulu ekufakeni imibala kwiplastiki okwangoku, edla ngokwenziwa yi-carrier resin, i-pigment kunye nezongezo. Inani elikhulu lezifundo libonise ukuba ukusebenzisa i-calcium carbonate, i-wollastonite okanye i-barium sulfate ukutshintsha ezinye ii-pigment ukulungiselela i-masterbatch yombala kunokuphucula ukusasazeka kwee-pigment kunye nokunciphisa iindleko zemveliso ngaphandle kokunciphisa ukusebenza kombala we-masterbatch yombala. Ezinye izifundo zibonise ukuba i-masterbatch yombala elungiselelwe ngokugaywa okumanzi kwe-calcium bicarbonate endaweni ye-titanium dioxide, xa isixa sokutshintshwa singama-20%, ukusebenza kombala kuhlala kungatshintshi, kwaye ukusebenza kufana kakhulu nokombala ococekileyo, ngomahluko omncinci wombala.

Njengomvelisi we i-calcium enzimaumsi wokugayaumatshini,I-HCQ, uthotho lwe-HC olukhulu lwe-calcium enzima iRaymond mill, I-HLM enzima ye-calcium erhabaxa ethe nkqoukugayaumsilokunye nezinye i-calcium enzimaumsi wokugayaIzixhobo eziveliswe yi-HCMilling (Guilin Hongcheng) zisetyenziswe kakhulu kwaye zifumene udumo oluhle kwimveliso eyomileyo yangaphambili ye-wet-end heavy calcium. Ukuba unesidingo semveliso yokusila i-wet-end heavy calcium kwaye ufuna izixhobo zokugaya i-dry-end, nceda unxibelelane ne-HCM ukuze ufumane iinkcukacha ngezixhobo.
