Guilin Hongkaolin igwe igwe kwụ ọtọ

Guilin Hongcheng egweri akụrụngwa emepụtamụtara na calcined kaolin egweri ngwaahịa na-bụ-eji na mkpuchi ụlọ ọrụ, nke a na-eji dị ka a filler na agba, n'otu aka ahụ na-arụ ọrụ nke anụ ahụ ndochi, n'aka nke ọzọ nwere ụfọdụ akọrọ mkpuchi ike.Yabụ, kedu ihe ndeksi chọrọ nke ngwaahịa kaolin egweri calcined?

Ndekọ ngwaahịa nke calcined kaolin maka mkpuchi na-agụnyekarị ọcha, nha urughuru, ike mkpuchi, mgbasa, 325 mesh sieve residue, uru nnabata mmanụ, ntinye ego, uru pH, nguzogide ihu igwe na ihe ndị ọzọ:

1.White ogo

Ọcha bụ isi index nke calcined kaolin, nke dị elu ka mma.A na-ejikwa agba agba agba agba na-acha ọcha dị ka isi agba na agba nne. ọcha kwesịrị ịbụ ma ọ dịkarịa ala karịa 90%, ụfọdụ ndị na-emepụta ihe na-achọ ọbụna karịa 93%.Nkwụsi ike nke ogo ọcha dị ezigbo mkpa, ma ọ bụrụ na mgbanwe ahụ dị oke ibu iji metụta arụmọrụ anya nke mkpuchi ahụ, na-eme ka ọdịiche dị iche iche nke agba dị iche iche nke ngwaahịa dị n'okpuru otu usoro.

2.Granularity

urughuru size bụ n'ezie ihe index nke onodi, mkpuchi emepụta adịkarịghị ozugbo ịchọpụta urughuru size.Otú ọ dị, n'ihi na ndị ọzọ na-egosi nke calcined kaolin na-metụtara kpọmkwem urughuru size, ma ọ bụrụ na urughuru size adịghị mma zuru oke, ma ọ bụ na-erughị eru, ọ ga-egosipụta site ndị ọzọ egosi.Maka onye na-emepụta kaolin calcined, ndepụta nyocha nke ngwaahịa emechara kwesịrị ịbụ-2 μm na ihe dịka 80%.N'ezie, arụmọrụ nke ngwaahịa ndị dị iche iche na-emepụta ga-adị iche, ma ọ bụrụ na ndị ọzọ na-egosi na-ruru eru, urughuru size chọrọ nwekwara ike ibelata.

The urughuru size na-tumadi emetụta site yi nke raw ore na okpomọkụ nke calcination.The eyi ike kpebisiri ike site àgwà nke raw ore, nke tumadi emetụta urughuru size nke akụrụngwa ogbo, na calcination okpomọkụ tumadi emetụta urughuru size nke ntụ ntụ mgbe kiln.Maka mkpuchi calcination kaolin, calcination nke ọkara okpomọkụ (1000 ~ 1200 ℃), a na-ahọrọ okpomọkụ calcination kacha mma na usoro amorphous gbanwere ka ọ bụrụ silicon aluminum spinel frasi, nke na-emepụta usoro mgbasawanye porous, na-ebute mmepe pore, na uru abrasion nke ngwaahịa dịtụ ala.

3.Ikpuchi ike

Ike mkpuchi bụ ndepụta kachasị mkpa nke kaolin calcined.The finer na ntụ ntụ, ndị ọzọ interface kpụrụ na mkpuchi, ike refraction na echiche nke ìhè, karịsịa mgbe urughuru size hà na wavelength nke ìhè a na-ahụ anya, nwere ike ịgbasa mmetụta, nwere ike na-emepụta kasị ukwuu mkpuchi ike. mgbe ihe na-erughị uru a, ike mkpuchi ga-adị ntakịrị n'ihi ọdịiche nke ìhè.

Maka ezigbo kaolin, ma ọ nwere ike gbasaa kpamkpam na mkpuchi ahụ bụkwa ihe dị mkpa na-emetụta ike mkpuchi ya.Ọ bụ ezie na calcination na-eme ka ike mkpuchi nke kaolin dịkwuo mma na mkpuchi mmiri, ọ dịghị mkpa.N'ọnọdụ ụfọdụ, ọ dị mfe sintering na-etolite keadighi rarii ahụ, ma na-eme ka mkpuchi ike ibelata, na ọ na-apụghị iji maka mkpuchi ma ọlị. Nsogbu ọzọ bụ na calcination n'okpuru 1000 ℃ mgbe ụfọdụ na-emepụta a ìhè red agba, nke dị nnọọ njọ. maka ọcha pigmenti.1050℃ na superfine ntụ ntụ.

4.Dissiveness

Ụlọ ọrụ mkpuchi ụlọ kwuru mgbasa, na echiche ahụ bụ otu.Ọ bụ ezie na kaolin calcined abanyela ntụ ntụ ultrafine, nke nwere nkezi urughuru nke 1 μ m ma ọ bụ ihe na-erughị ya, na agba, na nnukwu viscosity nne na nna mmanya, ihe ndị ahụ anaghị ekewa ma chịkọta ọnụ.A na-akpọ ike nke kaolin calcined ịgbasa na usoro mkpuchi.Mgbasa nke kaolin calcined dị mma.Ọ bụrụ na ọkwa egweri na-ezute ihe ikpeazụ a chọrọ, enwere ike ịgbasa ya n'ime usoro mkpuchi.

Mgbasa nke kaolin calcined metụtara mmetụta ikpeazụ nke igweri.Ọ bụrụ na 45 μ m ma ọ bụ ihe buru ibu dị n'ime usoro nhazi superfine, ọ gaghị agbasasị na usoro mkpuchi.Ihe achọrọ maka ndeksi a bụ ihe na-erughị 45 μm, na nke nta, ka mma.Ọ bụrụ na mgbasa nke titanium dioxide nwere ike iru 25 μm, kwekọrọ na ọkwa egweri kwesịrị ịhọrọ 4 ma ọ bụ karịa.

5.325 ntupu sieve fọdụrụ

325 mesh sieve residue bụ ihe dị mkpa index, ihe a chọrọ nke mkpuchi na nke a index bụ <0.02%, na nta nke ọma. nhazi ultrafine.Ihe ọzọ na-emetụta ya bụ adịghị ọcha, agwakọta ya na adịghị ọcha nwere mmetụta doro anya na ọdịnaya nyocha nke ntupu 325.

6.Oil absorption uru

The mmanụ absorption uru nke calcined kaolin bụ 50g / 100g ~ 60g / 100g bụ agafeghị oke, mmanụ absorption ego dị oke elu, mkpuchi viscosity mere na otu usoro bụ nnukwu, iji belata viscosity, ego nke agba isi ga- mụbaa ọnụ ahịa;uru ntinye mmanụ dị oke ala, mkpuchi e mere dị mfe iji dozie, na mmeghe nke mmeghe adịghị mma.The mmanụ absorption uru nke kaolin bụ urughuru size nkesa, porosity, kpọmkwem elu ebe, na ọka ụdị irighiri.The urughuru size bụ obere, kpọmkwem n'elu ebe bụ ibu, na mmanụ absorption uru bụ

7.Settlement olu

The mmanụ absorption uru nke calcined kaolin bụ 50g / 100g ~ 60g / 100g bụ agafeghị oke, mmanụ absorption ego dị oke elu, mkpuchi viscosity mere na otu usoro bụ nnukwu, iji belata viscosity, ego nke agba isi ga- mụbaa ọnụ ahịa;uru ntinye mmanụ dị oke ala, mkpuchi e mere dị mfe iji dozie, na mmeghe nke mmeghe adịghị mma.The mmanụ absorption uru nke kaolin bụ urughuru size nkesa, porosity, kpọmkwem elu ebe, na ọka ụdị irighiri.The urughuru size bụ obere, kpọmkwem n'elu ebe bụ ibu, na mmanụ absorption uru bụ elu.

8.pH uru

Uru pH na-egosipụta acid na alkalinity nke kaolin calcined, yana uru pH kwesịrị ịdị n'etiti 6 na 8, n'ụzọ dị nso na nnọpụiche.PH nke calcined kaolin n'onwe ya na-anọpụ iche, ya mere a chọghị mgbanwe PH na ụlọ ọrụ mkpuchi.

9.Weather iguzogide

Mgbe a na-eji agba na agba agba agba, ihe nkiri agba site na anyanwụ na mmiri ozuzo, ga-atụgharị edo edo, hapụ ìhè na ntụ ntụ.Ike nke pigmenti iguzogide mgbanwe ndị a ka a na-akpọ nguzogide ihu igwe.Calcined kaolin enweghị ọrụ kemịkalụ siri ike na ọkụ, yabụ ọ nwere ezigbo nguzogide ihu igwe.

10.Ndị ọzọ egosi

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
