Guilin Hongkaolin nkqo yokusila

Guilin Hongcheng abavelisi bezixhobo zokusilawafunda ukuba i-calcined imveliso yokusila i-kaolin isetyenziswa ikakhulu kwishishini lokugquma, elisetyenziswa njengesizalisi kwipeyinti, kwelinye icala lidlala indima yokuzaliswa komzimba, kwelinye icala linomkhosi othile owomileyo wokugquma.Ke, zithini iimfuno zesalathiso seemveliso zokusila i-kaolin ecalcined?

Izalathiso zemveliso ye-kaolin ene-calcined yokwaleka ikakhulu ibandakanya ubumhlophe, ubungakanani bamasuntswana, amandla okugquma, ukusasazwa, intsalela ye-mesh ye-325, ixabiso lokufunxa i-oyile, umthamo wokubekwa, ixabiso le-pH, ukumelana nemozulu njalo njalo:

1.Idigri emhlophe

ubumhlophe sisalathiso sokuqala se-calcined kaolin, iphezulu ingcono.Ipeyinti yombala nayo yenziwe ngepeyinti emhlophe njengepeyinti esisiseko kunye nombala womama.ubumhlophe kufuneka bube bukhulu ngaphezu kwe-90%, abanye abavelisi bafuna ngaphezu kwe-93%.Ukuzinza kwesidanga esimhlophe kubaluleke kakhulu, ukuba ukuguquguquka kukhulu kakhulu ukuchaphazela ukusebenza kwe-optical yokwambathisa, okukhokelela kumbala wemibala yeebhetshi ezahlukeneyo zeemveliso phantsi kwefomula efanayo.

2.Granularity

Ubungakanani besuntswana ngokwenene isalathiso sokumelwa, abavelisi bokwambathisa abafane babone ubungakanani bamasuntswana.Nangona kunjalo, ngenxa yokuba ezinye izibonakaliso ze-kaolin e-calcined zihambelana ngokuthe ngqo kwi-particle size, ukuba ubungakanani be-particle ayilungile ngokwaneleyo, okanye ayifanelekanga, iya kubonakaliswa ngezinye izibonakaliso.Kumenzi we-kaolin e-calcined, isalathisi sokuhlola imveliso egqityiweyo kufuneka ibe-2 μ m malunga ne-80%.Ngokuqinisekileyo, ukusebenza kweemveliso eziveliswa yizinto eziluhlaza ezahlukeneyo ziya kuhluka, kwaye ukuba ezinye izikhombisi zifanelekile, iimfuno zesayizi ye-particle nazo zingancitshiswa.

Ubungakanani bamasuntswana buchaphazeleka ikakhulu kukunxitywa kwentsimbi ekrwada kunye nobushushu becalcination.Ikhono lokunxiba lichongwa ngumgangatho we-ore ekrwada, echaphazela ubukhulu becala ubungakanani benqanaba lezinto ezikrwada, kwaye ubushushu be-calcination buchaphazela ubukhulu becala ubungakanani bepowder emva komlilo.Kubala i-kaolin yokwambathisa, ubushushu obuphakathi calcination (1000 ~ 1200 ℃), elona qondo lobushushu lokubala likhethwa kwinqanaba le-amorphous elisanda kutshintshwa kwi-silicon ye-aluminium spinel isigaba, esivelisa isakhiwo sokwandiswa kwe-porous, okukhokelela kuphuhliso lwe-pore, kunye nexabiso le-abrasion ye-amorphous. imveliso iphantsi ngokwentelekiso.

3.Ukugquma amandla

Amandla okugubungela isalathiso esibaluleke kakhulu se-calcined kaolin.I-powder icolile, i-interface eyongeziweyo eyenziwe kwi-coating, inamandla ngakumbi ukuchaswa kunye nokubonakaliswa kokukhanya, ngakumbi xa ubungakanani besuntswana bulingana nobude bokukhanya okubonakalayo, kunomphumo oqinileyo wokusasaza, unokuvelisa amandla amakhulu okugubungela, xa lingaphantsi kweli xabiso, amandla okugquma aya kuba ncinane ngenxa yokwahluka kokukhanya.

Kuba i-kaolin entle kakhulu, ingaba inokuthi isasazwe ngokupheleleyo kwisambatho nayo yinto ebalulekileyo echaphazela amandla ayo okugquma.Nangona ukubalwa kuphucula amandla okugquma e-kaolin kwi-coating esekwe emanzini, ayibalulekanga.Kwezinye iimeko, kulula ukuntywila kunye nokwenza amasuntswana arhabaxa, kodwa yenza amandla okugquma anciphise, kwaye ayinakusetyenziselwa ukugquma kwaphela.Enye ingxaki kukuba ukubala ngaphantsi kwe-1000℃ ngamanye amaxesha kuvelisa isigaba esibomvu esikhanyayo, esibi kakhulu. eyebala elimhlophe.1050℃ kunye nomgubo ocolekileyo.

4.Ukusasazeka

Ishishini lasekhaya ukutyabeka wathi ukusasazwa, kwaye ingcamango iyafana.Nangona i-calcined kaolin iye yafumana umgubo we-ultrafine, kunye nobukhulu be-particle ye-1 μ m okanye ngaphantsi, kwipeyinti, kwi-viscosity ephezulu yotywala bomzali, amaqhekeza awahlukani kodwa ahlanganiswe kunye.Ukukwazi kwe-kaolin e-calcined ukusasaza kwindlela yokwaleka kuthiwa yi-dispersion.Ukusasazwa kwe-kaolin ene-calcined kulungile.Ukuba ibakala lokugaya lihlangabezana neemfuno zokugqibela, linokusasazwa ngaphakathi kwenkqubo yokwaleka.

Ukusasazwa kwe-kaolin e-calcined kuhambelana nesiphumo sokugqibela sokugaya.Ukuba i-45 μ m okanye iinqununu ezinkulu ziqulethwe kwinkqubo yokucubungula i-superfine, ayiyi kusasazwa kwinkqubo yokugqoka.Imfuno yesi salathisi ingaphantsi kwe-45 μ m, kwaye incinci, ingcono.Ukuba ukusabalalisa kwe-titanium dioxide kunokufikelela kwi-25 μ m, ehambelana nebakala lokugaya kufuneka likhethwe njenge-4 okanye ngaphezulu.

5.325 intsalela yemesh ye-sieve

I-325 mesh sieve isala isalathiso esibalulekileyo, imfuno yokwambathisa kule index yi <0.02%, kwaye incinci ingcono.325 i-mesh sieve nayo inxulumene kakhulu nesiphumo sokugqibela sokugaya, ifuna akukho 45 μ m okanye amasuntswana amakhulu ngexesha. ukusetyenzwa kwe-ultrafine.Enye into echaphazelayo kukungacoceki, okuxutywe kunye nokungcola kunempembelelo ebonakalayo kumxholo wokuhlola we-325 mesh.

6.Ixabiso lokufunxa i-oyile

Ixabiso lokufunxa ioli ye-calcined kaolin yi-50g / 100g ~ 60g / 100g imodareyitha, inani lokufunxa ioli liphezulu kakhulu, i-viscosity yokugqoka eyenziwe ngefomula efanayo inkulu, ukwenzela ukunciphisa i-viscosity, inani lesiseko sepeyinti kufuneka. ukwandisa iindleko;ixabiso lokufunxa ioli liphantsi kakhulu, isambatho esenziwe kulula ukuhlaliswa, kwaye ukusebenza kokuvula akulunganga.Ixabiso lokufunxa i-oyile ye-kaolin yi-particle size distribution, porosity, indawo ethile yomphezulu, kunye nohlobo lweenkozo zamasuntswana.Ubungakanani be-particle buncinci, indawo ethile yendawo inkulu, kunye nexabiso lokufunxa ioli

7.Umthamo wokuhlaliswa

Ixabiso lokufunxa ioli ye-calcined kaolin yi-50g / 100g ~ 60g / 100g imodareyitha, inani lokufunxa ioli liphezulu kakhulu, i-viscosity yokugqoka eyenziwe ngefomula efanayo inkulu, ukwenzela ukunciphisa i-viscosity, inani lesiseko sepeyinti kufuneka. ukwandisa iindleko;ixabiso lokufunxa i-oyile liphantsi kakhulu, i-coating eyenziwe kulula ukuyihlalisa, kwaye ukusebenza kokuvula akulungile.Ixabiso lokufunxa i-oyile ye-kaolin yi-particle size distribution, porosity, indawo ethile yomphezulu, kunye nohlobo lweenkozo zamasuntswana.Ubungakanani be-particle buncinci, indawo ethile yendawo inkulu, kwaye ixabiso lokufunxa ioli liphezulu.

8.pH ixabiso

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 isondele kwi-neutral.I-PH ye-kaolin e-calcined ngokwayo ayithathi cala, ngoko ke ukuguqulwa kwe-PH akufuneki kushishino lokwaleka.

9.Ukumelana nemozulu

Emva kokuba i-pigment yenziwe ngepeyinti kunye ne-daub, ifilimu yepeyinti ngelanga kunye nemvula, iya kuba tyheli, ilahlekelwe ukukhanya kunye nomgubo.Ukukwazi kwemibala ukumelana nolu tshintsho kubizwa ngokuba kukuxhathisa kwemozulu.I-kaolin ene-calcined ayinayo imichiza eyomeleleyo ekukhanyeni, ngoko inokumelana nemozulu elungileyo.

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
