Umatshini wokusila othe nkqo weGuilin Hongkaolin

Abavelisi bezixhobo zokugaya zaseGuilin HongchengNdifunde ukuba iimveliso zokugaya i-kaolin ene-calcined zisetyenziswa kakhulu kushishino lokugquma, olusetyenziswa njengesizalisi kwipeyinti, kwelinye icala lidlala indima yokuzalisa ngokwasemzimbeni, kwelinye icala linamandla athile okugquma. Ngoko ke, zithini iimfuno zesalathiso seemveliso zokugaya i-kaolin ene-calcined?

Ii-index zemveliso ze-calcined kaolin zokugquma ziquka ubumhlophe, ubungakanani besuntswana, amandla okugquma, ukusasazwa, intsalela yesihluzo se-mesh engama-325, ixabiso lokufunxwa kweoyile, umthamo wokufakwa, ixabiso le-pH, ukumelana nemozulu njalo njalo:

1. Isidanga esimhlophe

Ubumhlophe yeyona nto iphambili kwi-calcined kaolin, kokukhona iphezulu ingcono. Ipeyinti yombala nayo yenziwe ngepeyinti emhlophe njengepeyinti esisiseko kunye nomama wombala. Ubumhlophe kufuneka bube ngaphezu kwama-90%, abanye abavelisi bade bafune ngaphezu kwama-93%. Uzinzo lwezinga elimhlophe lubaluleke kakhulu, ukuba ukuguquguquka kukhulu kakhulu ukuba kungachaphazela ukusebenza kwe-optical kwengubo, nto leyo ebangela umahluko wombala kwiibhetshi ezahlukeneyo zeemveliso phantsi kwefomula efanayo.

2. Ubuninzi begranularity

Ubungakanani bamasuntswana ngokwenene luphawu lokumelwa, abavelisi bokugquma abafane babone ngqo ubungakanani bamasuntswana. Nangona kunjalo, ngenxa yokuba ezinye izikhombisi ze-kaolin ene-calcined zinxulumene ngokuthe ngqo nobukhulu bamasuntswana, ukuba ubungakanani bamasuntswana abulunganga ngokwaneleyo, okanye abufanelekanga, buya kubonakala ngezinye izikhombisi. Kumenzi we-kaolin ene-calcined, isalathisi sokuhlolwa kwemveliso egqityiweyo kufuneka sibe yi-2 μ m malunga ne-80%. Kakade ke, ukusebenza kweemveliso eziveliswe zizinto ezahlukeneyo ezikrwada kuya kwahluka, kwaye ukuba ezinye izikhombisi ziyafaneleka, iimfuno zobukhulu bamasuntswana nazo zinokuncitshiswa.

Ubungakanani besuntswana buchaphazeleka kakhulu kukuguguleka kwe-ore eluhlaza kunye nobushushu be-calcination. Amandla okuguguleka amiselwa ngumgangatho we-ore eluhlaza, echaphazela ubukhulu besuntswana kwinqanaba lezinto eziluhlaza, kwaye ubushushu be-calcination buchaphazela ubukhulu besuntswana yepowder emva kwe-oven. Kwi-calcination kaolin yokugquma, i-calcination yobushushu obuphakathi (1000 ~ 1200℃), ubushushu be-calcination obufanelekileyo bukhethwa kwisigaba esingaguqukiyo esisandula ukutshintshwa sibe sisigaba se-silicon aluminium spinel, esivelisa isakhiwo sokwandiswa kwe-porous, okubangela uphuhliso lwe-pore, kwaye ixabiso le-abrasion yemveliso liphantsi.

3. Amandla okugquma

Amandla okugquma yeyona nto ibalulekileyo kwi-kaolin ekhaltsini. Okukhona umgubo ucolekile, kokukhona ujongano olungakumbi lwenziwe kwi-coating, kokukhona ukurhawuzelelwa nokubonakaliswa kokukhanya kuqina, ingakumbi xa ubungakanani besuntswana bulingana nobude bokukhanya okubonakalayo, bunefuthe elinamandla lokusasazeka, bunokuvelisa amandla amakhulu okugquma, xa bungaphantsi kweli xabiso, amandla okugquma aya kuba mancinci ngenxa yokusasazeka kokukhanya.

Kwi-kaolin ecolekileyo kakhulu, nokuba ingasasazeka ngokupheleleyo na kwi-coating nayo yinto ebalulekileyo echaphazela amandla ayo okugquma. Nangona i-calcination iphucula amandla okugquma e-kaolin kwi-coating esekelwe emanzini, ayibalulekanga. Kwezinye iimeko, kulula ukuyitshisa yenze amasuntswana arhabaxa, kodwa yenza amandla okugquma anciphe, kwaye ayinakusetyenziselwa ukugquma konke konke. Enye ingxaki kukuba i-calcination engaphantsi kwe-1000℃ ngamanye amaxesha ivelisa i-clicination ebomvu ekhanyayo, nto leyo embi kakhulu kwi-pigment emhlophe. I-1050℃ kunye ne-superfine powder.

4. Ukusasazeka

Ishishini lokugquma lasekhaya lathi ukusasazeka, kwaye ingcamango iyafana. Nangona i-kaolin e-calcined iye yadlula kwi-ultrafine powder, enobukhulu obuphakathi be-particle ye-1 μ m okanye ngaphantsi, kwipeyinti, kwi-high viscosity parent liquor, amaqhekeza awahlukani kodwa ahlanganiswe ndawonye. Amandla e-kaolin e-calcined okusasaza kwinkqubo yokugquma abizwa ngokuba yi-dispersion. Ukusasazeka kwe-kaolin e-calcined kulungile. Ukuba umgangatho wokusila uyahlangabezana neemfuno zokugqibela, unokusasazwa ngaphakathi kwenkqubo yokugquma.

Ukusasazeka kwe-kaolin e-calcined kunxulumene nesiphumo sokugqibela sokusila. Ukuba amasuntswana angama-45 μ m okanye amakhulu aqulethwe kwinkqubo yokucubungula i-superfine, akayi kusasazwa kwinkqubo yokugquma. Imfuneko yale index ingaphantsi kwama-45 μ m, kwaye okuncinci, kokukhona kungcono. Ukuba ukusasazeka kwe-titanium dioxide kunokufikelela kwi-25 μ m, okuhambelana nomgangatho wokusila kufuneka kukhethwe njenge-4 okanye ngaphezulu.

Intsalela yesihluzo se-mesh engu-5.325

Intsalela yesihluzo se-mesh engu-325 sisalathisi esibalulekileyo, imfuneko yokugquma kwesi salathisi yi-<0.02%, kwaye okukhona incinci kokukhona ingcono. Isihluzo se-mesh esingu-325 sikwanxulumene kakhulu nesiphumo sokugqibela sokusila, esingafunekiyo i-45 μ m okanye amasuntswana amakhulu ngexesha lokucubungula okucolekileyo kakhulu. Enye into echaphazelayo kukungcola, okuxutywe nokungcola kunempembelelo ebonakalayo kumxholo wokucoca we-mesh engu-325.

6. Ixabiso lokufunxwa kweoyile

Ixabiso lokufunxwa kweoyile ye-calcined kaolin yi-50g / 100g ~ 60g / 100g liphakathi, ubungakanani bokufunxwa kweoyile buphezulu kakhulu, i-viscosity yokugquma eyenziwe ngefomula efanayo inkulu, ukuze kuncitshiswe i-viscosity, ubungakanani besiseko sepeyinti kufuneka bonyuse iindleko; ixabiso lokufunxwa kweoyile liphantsi kakhulu, i-coating eyenziweyo kulula ukuyilungisa, kwaye ukusebenza kokuvula akulunganga. Ixabiso lokufunxwa kweoyile ye-kaolin kukusasazwa kobungakanani be-particle, i-porosity, indawo ethile yomphezulu, kunye nohlobo lweenkozo ze-particles. Ubungakanani be-particle buncinci, indawo ethile yomphezulu inkulu, kwaye ixabiso lokufunxwa kweoyile liphezulu kakhulu.

7. Umthamo wentlawulo

Ixabiso lokufunxwa kweoyile ye-calcined kaolin yi-50g / 100g ~ 60g / 100g liphakathi, ubungakanani bokufunxwa kweoyile buphezulu kakhulu, i-viscosity yokugquma eyenziwe ngefomula efanayo inkulu, ukuze kuncitshiswe i-viscosity, ubungakanani besiseko sepeyinti kufuneka bonyuse iindleko; ixabiso lokufunxwa kweoyile liphantsi kakhulu, i-coating eyenziweyo kulula ukuyilungisa, kwaye ukusebenza kokuvula akulunganga. Ixabiso lokufunxwa kweoyile ye-kaolin kukusasazwa kobungakanani be-particle, i-porosity, indawo ethile yomphezulu, kunye nohlobo lweenkozo ze-particles. Ubungakanani be-particle buncinci, indawo ethile yomphezulu inkulu, kwaye ixabiso lokufunxwa kweoyile liphezulu.

Ixabiso le-8.pH

Ixabiso le-pH libonisa i-asidi kunye ne-alkalinity ye-kaolin ene-calcined, kwaye ixabiso le-pH kufuneka libe phakathi kwe-6 kunye ne-8, ngokusisiseko lisondele kwi-neutral. I-PH ye-kaolin ene-calcined ngokwayo ayithathi cala, ngoko ke ukuguqulwa kwe-PH akufuneki kwishishini lokugquma.

9. Ukumelana nemozulu

Emva kokuba umbala wenziwe ngepeyinti kunye ne-daub, ifilimu yepeyinti edlula elangeni nasemvuleni, iya kuba tyheli, ilahlekelwe kukukhanya kunye nomgubo. Amandla emibala yokumelana nolu tshintsho abizwa ngokuba kukumelana nemozulu. I-kaolin ene-calcined ayinayo imisebenzi enamandla yeekhemikhali ekukhanyeni, ngoko ke inokumelana nemozulu kakuhle.

10. Ezinye izalathisi

ther index requirements for calcined kaolin, acid and alkali resistance, mixing performance, wet performance, density, etc., these are the common characteristics of all calcined kaolin, some are not digital indicators. It is worth paying attention to that, no matter which index of kaolin, the stability of the index is the most important, if the fluctuation is too big, it will bring bad influence to the paint users, affect the overall performance of the paint. As the production equipment of calcined kaolin mill products, it has an important influence on the whiteness, particle size and 325 mesh residue of calcinined kaolin mill products. Guilin Hongcheng grinding equipment can be ground kaolin to 80-2500 mesh for the production of coating, grinding equipment with high output, low energy consumption, consulting equipment price can contact the email:mkt@hcmilling.com
