Isigayo esiqondile sikaGuilin Hongkaolin

Abakhiqizi bemishini yokugaya iGuilin HongchengNgifunde ukuthi imikhiqizo yokugaya i-kaolin ene-calcined isetshenziswa kakhulu embonini yokugqoka, esetshenziswa njengesigcwalisi kupende, ngakolunye uhlangothi idlala indima yokugcwalisa ngokomzimba, ngakolunye uhlangothi inamandla athile okumboza okomile. Ngakho-ke, yiziphi izidingo zenkomba zemikhiqizo yokugaya i-kaolin ene-calcined?

Izinkomba zomkhiqizo ze-kaolin ene-calcined yokumboza zifaka phakathi ubumhlophe, usayizi wezinhlayiya, amandla okumboza, ukuhlakazeka, insalela yesihlungo se-mesh engu-325, inani lokumuncwa kwamafutha, ivolumu yokufaka, inani le-pH, ukumelana nesimo sezulu nokunye:

1. Izinga elimhlophe

Ubumhlophe buyinkomba eyinhloko ye-kaolin e-calcined, uma iphakeme iba ngcono. Upende wombala wenziwa nangopende omhlophe njengopende oyisisekelo kanye nomama wombala. Ubumhlophe kufanele okungenani bube ngaphezu kuka-90%, abanye abakhiqizi badinga ngisho nangaphezu kuka-93%. Ukuzinza kwezinga elimhlophe kubaluleke kakhulu, uma ukuguquguquka kukhulu kakhulu ukuthi kungathinti ukusebenza kokukhanya kwengubo, okuholela ekwehlukeni kombala kwamaqoqo ahlukene emikhiqizo ngaphansi kwefomula efanayo.

2. Ubuningi

Usayizi wezinhlayiya empeleni uyinkomba yokumelwa, abakhiqizi bokumboza abavamile ukubona ngqo usayizi wezinhlayiya. Kodwa-ke, ngenxa yokuthi ezinye izinkomba ze-kaolin ene-calcined zihlobene ngqo nosayizi wezinhlayiya, uma usayizi wezinhlayiya unganele, noma ungafaneleki, uzobonakala ngezinye izinkomba. Kumkhiqizi we-kaolin ene-calcined, inkomba yokuhlola yomkhiqizo oqediwe kufanele ibe yi-2 μ m cishe ku-80%. Vele, ukusebenza kwemikhiqizo ekhiqizwe izinto zokusetshenziswa ezahlukene kuzohluka, futhi uma ezinye izinkomba zifanelekile, izidingo zosayizi wezinhlayiya nazo zingancishiswa.

Usayizi wezinhlayiya uthintwa kakhulu ukuguguleka kwe-ore eluhlaza kanye nokushisa kwe-calcination. Amandla okuguguleka anqunywa yikhwalithi ye-ore eluhlaza, ethinta kakhulu usayizi wezinhlayiya zesigaba sezinto zokusetshenziswa, kanti izinga lokushisa le-calcination lithinta kakhulu usayizi wezinhlayiya zempuphu ngemva kwesitofu. Ukuze kufakwe i-calcination kaolin, i-calcination yokushisa okuphakathi (1000~1200℃), izinga lokushisa elifanele le-calcination likhethwa esigabeni esingaguquki esisanda kushintshwa sibe yisigaba se-silicon aluminium spinel, esikhiqiza isakhiwo sokukhulisa i-porous, okuholela ekuthuthukisweni kwe-pore, kanye nenani lokuguguleka lomkhiqizo liphansi kakhulu.

3. Amandla okumboza

Amandla okumboza yinkomba ebaluleke kakhulu ye-kaolin e-calcined. Uma i-powder incane, lapho kwakheka khona isikhombimsebenzisi esikhudlwana embozweni, kulapho ukukhanya kuqina khona ukugqama nokubonakaliswa, ikakhulukazi lapho usayizi wezinhlayiya ulingana nobude bokukhanya okubonakalayo, unomphumela wokuhlakazeka onamandla kakhulu, ungakhiqiza amandla amakhulu okumboza, uma engaphansi kwaleli nani, amandla okumboza azoba mancane ngenxa yokusabalala kokukhanya.

Uma i-kaolin incane kakhulu, ukuthi ingahlakazeka ngokuphelele yini embozweni nakho kuyisici esibalulekile esithinta amandla ayo okumboza. Nakuba i-calcination ithuthukisa amandla okumboza e-kaolin embozweni osekelwe emanzini, ayibalulekile. Kwezinye izimo, kulula ukuyishisa futhi yakhe izinhlayiya eziqinile, kodwa yenza amandla okumboza anciphe, futhi ayikwazi ukusetshenziselwa ukumboza nhlobo. Enye inkinga ukuthi i-calcination engaphansi kuka-1000℃ ngezinye izikhathi ikhiqiza isigaba esibomvu esikhanyayo, esibi kakhulu kuma-pigment amhlophe. 1050℃ kanye ne-powder enhle kakhulu.

4. Ukuhlakazeka

Imboni yokumboza yasekhaya ithe ukuhlakazeka, futhi umqondo uyafana. Nakuba i-kaolin ene-calcined iye yadlula i-ultrafine powder, enobukhulu bezinhlayiya obumaphakathi obungu-1 μ m noma ngaphansi, kupende, ku-high viscosity parent liquor, izinhlayiya azihlukene kodwa ziqoqwe ndawonye. Amandla e-kaolin ene-calcined okuhlakazeka ohlelweni lokumboza abizwa ngokuthi ukuhlakazeka. Ukuhlakazeka kwe-kaolin ene-calcined kuhle. Uma izinga lokugaya lihlangabezana nezidingo zokugcina, lingahlakazeka ngaphakathi kohlelo lokumboza.

Ukusabalala kwe-kaolin ene-calcined kuhlobene nomphumela wokugcina wokugaya. Uma izinhlayiya ezingu-45 μ m noma ezinkulu ziqukethwe enqubweni yokucubungula okuhle kakhulu, ngeke zisakazwe ohlelweni lokumboza. Isidingo salolu hlu singaphansi kuka-45 μ m, futhi uma zincane, kungcono. Uma ukusabalala kwe-titanium dioxide kungafinyelela ku-25 μ m, okuhambisana nebanga lokugaya kufanele kukhethwe njengo-4 noma ngaphezulu.

5.325 insalela yesihluzo se-mesh

I-residue yesihlungo se-mesh engu-325 iyinkomba ebalulekile, isidingo sokumboza lesi sikhombisi singaphansi kuka-0.02%, kanti uma sincane kungcono. Isihlungo se-mesh esingu-325 sihlobene kakhulu nomphumela wokugcina wokugaya, okungadingi ama-μm angu-45 noma izinhlayiya ezinkulu ngesikhathi sokucubungula okune-ultrafine. Esinye isici esithonya ukungcola, okuxutshwe nokungcola kunomthelela osobala kakhulu kokuqukethwe kokuhlola kwe-mesh engu-325.

6. Inani lokumuncwa kwamafutha

Inani lokumuncwa kwamafutha le-kaolin ene-calcium lingu-50g / 100g ~ 60g / 100g lilinganiselwe, inani lokumuncwa kwamafutha liphezulu kakhulu, i-viscosity yokumboza eyenziwe ngefomula efanayo inkulu, ukuze kuncishiswe i-viscosity, inani lesisekelo sopende kumele lenyuse izindleko; inani lokumuncwa kwamafutha liphansi kakhulu, i-coating eyenziwe kulula ukuyixazulula, futhi ukusebenza kokuvula akukuhle. Inani lokumuncwa kwamafutha le-kaolin ukusatshalaliswa kosayizi wezinhlayiya, ukugoba, indawo ethile yobuso, kanye nohlobo lwezinhlamvu zezinhlayiya. Usayizi wezinhlayiya mncane, indawo ethile yobuso inkulu, kanti inani lokumuncwa kwamafutha liyi

7. Umthamo wenkokhelo

Inani lokumuncwa kwamafutha le-kaolin ene-calcium lingu-50g / 100g ~ 60g / 100g lilinganiselwe, inani lokumuncwa kwamafutha liphezulu kakhulu, i-viscosity yokumboza eyenziwe ngefomula efanayo inkulu, ukuze kuncishiswe i-viscosity, inani lesisekelo sopende kumele lenyuse izindleko; inani lokumuncwa kwamafutha liphansi kakhulu, i-coating eyenziwe kulula ukuyixazulula, futhi ukusebenza kokuvula akukuhle. Inani lokumuncwa kwamafutha le-kaolin ukusatshalaliswa kosayizi wezinhlayiya, ukugoba, indawo ethile yobuso, kanye nohlobo lwezinhlamvu zezinhlayiya. Usayizi wezinhlayiya mncane, indawo ethile yobuso inkulu, futhi inani lokumuncwa kwamafutha liphakeme.

Inani le-pH elingu-8.8

Inani le-pH libonisa i-asidi kanye ne-alkalinity ye-kaolin ene-calcium, kanti inani le-pH kufanele libe phakathi kuka-6 no-8, cishe cishe licishe libe yi-neutral. I-PH ye-kaolin ene-calcium ngokwayo ayithathi hlangothi, ngakho-ke ukuguqulwa kwe-PH akudingeki embonini yokumboza.

9. Ukumelana nesimo sezulu

Ngemva kokuba umbala wenziwe ngopende nokudaya, ifilimu yopende edlula elangeni nasemvuleni, izophenduka iphuzi, ilahlekelwe ukukhanya kanye nempuphu. Amandla ombala wokumelana nalezi zinguquko abizwa ngokuthi ukumelana nesimo sezulu. I-kaolin ene-calcined ayinawo umsebenzi wamakhemikhali onamandla ekukhanyeni, ngakho-ke inokumelana nesimo sezulu okuhle.

10. Ezinye izinkomba

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
