Isigayo se-Guilin Hongkaolin esiqondile

Guilin Hongcheng abakhiqizi bemishini yokugayawafunda ukuthi imikhiqizo yokugaya i-kaolin e-calcined isetshenziswa ikakhulukazi embonini yokumboza, esetshenziswa njengesigcwalisi kupende, ngakolunye uhlangothi idlala indima yokugcwalisa ngokomzimba, ngakolunye uhlangothi inamandla athile okumboza okomile.Ngakho-ke, yiziphi izimfuneko zenkomba zemikhiqizo yokugaya i-kaolin ene-calcined?

Izinkomba zomkhiqizo we-kaolin e-calcined ukuze kuhlanganiswe ikakhulukazi ubumhlophe, usayizi wezinhlayiyana, amandla okuvala, ukusabalalisa, insalela yesisefo esingu-325, inani lokumunca uwoyela, ivolumu yokubeka, inani le-pH, ukumelana nesimo sezulu nokunye:

1.Iziqu ezimhlophe

ubumhlophe inkomba eyinhloko kaolin calcined, ephakeme kangcono.Upende wombala ubuye wenziwe ngopende omhlophe njengopende oyisisekelo kanye nombala womama. ubumhlophe kufanele okungenani bube ngaphezu kuka-90%, abanye abakhiqizi baze badinge okukhulu kuno-93%.Ukuzinza kwedigri emhlophe kubaluleke kakhulu, uma ukushintshashintsha kukukhulu kakhulu ukuthi kuthinte ukusebenza kokubona kwento enamathelayo, okuholela kumehluko wombala wamaqoqo ahlukene emikhiqizo ngaphansi kwefomula efanayo.

2.Imbudumbudu

Usayizi wezinhlayiya empeleni uyinkomba yokumelela, abakhiqizi bokumboza abavamile ukubona usayizi wezinhlayiyana ngokuqondile.Kodwa-ke, ngenxa yokuthi ezinye izinkomba ze-kaolin e-calcined zihlobene ngokuqondile nosayizi wezinhlayiyana, uma usayizi wezinhlayiyana ungalungile ngokwanele, noma ungafanelekile, uzobonakala ngezinye izinkomba.Kumkhiqizi we-kaolin e-calcined, inkomba yokuhlola yomkhiqizo oqediwe kufanele ibe-2 μ m cishe ku-80%.Yiqiniso, ukusebenza kwemikhiqizo ekhiqizwa yizinto ezihlukahlukene zokusetshenziswa kuzohluka, futhi uma ezinye izinkomba zifanelekile, izidingo zosayizi wezinhlayiyana nazo zingancishiswa.

Ubukhulu bezinhlayiyana buthinteka kakhulu ukuguga kwensimbi eluhlaza kanye nezinga lokushisa lokubala.Ikhono lokugqoka linqunywa ikhwalithi ye-ore eluhlaza, ethinta kakhulu usayizi wezinhlayiyana zesiteji sezinto ezingavuthiwe, futhi izinga lokushisa lokubala lithinta ikakhulukazi usayizi wezinhlayiyana zempushana ngemva komlilo.Ukuze kufakwe i-kaolin yokubala, izinga lokushisa eliphakathi nendawo (1000 ~ 1200℃), izinga lokushisa elilungile lokubala likhethwa esigabeni se-amorphous esisanda kuguqulwa sibe yi-silicon aluminium spinel isigaba, esikhiqiza isakhiwo sokunwebeka esinezimbotshana, okuholela ekuthuthukisweni kwembobo, kanye nenani lokuhuzuka umkhiqizo uphansi uma kuqhathaniswa.

3.Cover force

Amandla okuvala inkomba ebaluleke kakhulu ye-kaolin e-calcined.Uma impushana icwebezela, i-interface eyakhiwe ngaphezulu kwe-coating, i-refraction enamandla kanye nokubonakaliswa kokukhanya, ikakhulukazi uma usayizi wezinhlayiyana ulingana nobude be-wavelength bokukhanya okubonakalayo, unomphumela wokuhlakazeka onamandla kakhulu, ungaveza amandla amakhulu okusibekela, uma ingaphansi kwaleli nani, amandla okusibekela azoba mancane ngenxa yokuphambuka kokukhanya.

Ku-kaolin enhle kakhulu, noma ingahlakazeka ngokugcwele ekunambeni nakho kuyisici esibalulekile esithinta amandla ayo okusibekela.Nakuba ukubala kuthuthukisa amandla okuvala e-kaolin emanzini asekelwe emanzini, akubalulekile.Kwezinye izimo, kulula ukucwilisa bese kwakheka izinhlayiya ezimahhadla, kodwa kwenza amandla okusibekela anciphe, futhi angeke asetshenziselwe ukunameka nhlobo.Enye inkinga ukuthi ukubala ngaphansi kuka-1000℃ ngezinye izikhathi kukhiqiza isigaba esibomvu esilula, esibi kakhulu. okwemibala emhlophe.1050℃ kanye nempushana ecwebe kakhulu.

4.Ukuhlakazeka

Imboni yasekhaya enamathelayo yathi ukuhlakazeka, futhi umqondo uyafana.Nakuba i-kaolin e-calcined iye yaba yimpushana ye-ultrafine, enesilinganiso sosayizi wezinhlayiyana ezingu-1 μ m noma ngaphansi, kupende, kugologo womzali we-viscosity ophezulu, izinhlayiya azihlukene kodwa zihlanganiswe ndawonye.Ikhono le-kaolin e-calcined lokuhlakaza ohlelweni lokumboza libizwa ngokuthi i-dispersion.Ukuhlakazwa kwe-kaolin e-calcined kuhle.Uma ibanga lokugaya lihlangabezana nezidingo zokugcina, lingahlakazwa ngaphakathi kwesistimu yokugqoka.

Ukuhlakazwa kwe-kaolin e-calcined kuhlobene nomphumela wokugcina wokugaya.Uma u-45 μ m noma izinhlayiya ezinkulu ziqukethwe kunqubo yokucubungula ecwebile, ngeke ihlakazwe ohlelweni lokumboza.Imfuneko yale nkomba ingaphansi kuka-45 μ m, kanti encane, ingcono.Uma ukuhlakazwa kwe-titanium dioxide kungafinyelela ku-25 μ m, okuhambisana nebanga lokugaya kufanele kukhethwe njenge-4 noma ngaphezulu.

5.325 mesh isisefo insalela

I-325 mesh sieve insalela iyinkomba ebalulekile, imfuneko yokunamathela kule nkomba ingu-<0.02%, futhi encane engcono. ukucutshungulwa kwe-ultrafine.Esinye isici esinomthelela ukungcola, okuxubene nokungcola kunomthelela osobala kakhulu kokuqukethwe okuhlolwayo kwe-325 mesh.

6.Inani lokumunca uwoyela

Inani lokumuncwa kwamafutha e-kaolin e-calcined liyi-50g / 100g ~ 60g / 100g liphakathi, inani lokumuncwa kwamafutha liphezulu kakhulu, i-viscosity yokumboza eyenziwe ngefomula efanayo inkulu, ukuze kuncishiswe i-viscosity, inani lesisekelo sikapende kufanele ukwandisa izindleko;inani lokumuncwa kwamafutha liphansi kakhulu, i-coating eyenziwe kulula ukuxazulula, futhi ukusebenza kokuvula akukuhle.Ivelu yokumuncwa kukawoyela ye-kaolin wukusabalalisa usayizi wezinhlayiyana, i-porosity, indawo ethile engaphezulu, kanye nohlobo lwezinhlayiyana zohlamvu.Usayizi wezinhlayiyana mncane, indawo ethize ingaphezulu, futhi inani lokumunca uwoyela likhulu

7.Ivolumu yokukhokha

Inani lokumuncwa kwamafutha e-kaolin e-calcined liyi-50g / 100g ~ 60g / 100g liphakathi, inani lokumuncwa kwamafutha liphezulu kakhulu, i-viscosity yokumboza eyenziwe ngefomula efanayo inkulu, ukuze kuncishiswe i-viscosity, inani lesisekelo sikapende kufanele ukwandisa izindleko;inani lokumuncwa kwamafutha liphansi kakhulu, i-coating eyenziwe kulula ukuxazulula, futhi ukusebenza kokuvula akukuhle.Ivelu yokumuncwa kukawoyela ye-kaolin wukusabalalisa usayizi wezinhlayiyana, i-porosity, indawo ethile engaphezulu, kanye nohlobo lwezinhlayiyana zohlamvu.Usayizi wezinhlayiyana mncane, indawo ethile engaphezulu inkulu, futhi inani lokumunca uwoyela liphakeme.

8.pH inani

Inani le-pH libonisa i-asidi ne-alkalinity ye-kaolin e-calcined, futhi inani le-pH kufanele libe phakathi kuka-6 no-8, ngokuyisisekelo eduze nokungathathi hlangothi.I-PH ye-kaolin ebaliwe ngokwayo ayithathi hlangothi, ngakho-ke ukuguqulwa kwe-PH akudingekile embonini yokumboza.

9.Ukumelana nesimo sezulu

Ngemuva kokuthi i-pigment yenziwe ngopende kanye ne-daub, ifilimu kapende elangeni nemvula, izophenduka ibe phuzi, ilahlekelwe ukukhanya kanye nempushana.Ikhono le-pigments ukumelana nalezi zinguquko libizwa ngokuthi ukumelana nesimo sezulu.I-kaolin ene-calcined ayinawo amakhemikhali anamandla ekukhanyeni, ngakho inokumelana nesimo sezulu esihle.

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
