Guilin Hongkaolin injin niƙa mai tsayi

Masu kera kayan aikin niƙa na Guilin HongchengAn gano cewa ana amfani da kayayyakin niƙa na kaolin da aka yi da calcined a masana'antar shafa fenti, wanda ake amfani da shi azaman cika fenti, a gefe guda yana taka rawar cika jiki, a gefe guda kuma yana da wani ƙarfin rufewa. To, menene buƙatun ma'aunin samfuran niƙa na kaolin da aka yi da calcined?

Fihirisar samfurin kaolin da aka yi wa calcined don shafa sun haɗa da fari, girman barbashi, ƙarfin rufewa, watsawa, ragowar sieve na raga 325, ƙimar shan mai, girman ajiya, ƙimar pH, juriya ga yanayi da sauransu:

1. Digiri na fari

Fari shine babban ma'aunin kaolin da aka yi da calcined, mafi girma shine mafi kyau. An kuma yi fenti mai launi da farin fenti a matsayin fenti na tushe kuma launin uwar. Farin ya kamata ya zama aƙalla fiye da 90%, wasu masana'antun ma suna buƙatar fiye da 93%. Kwanciyar hankali na fari yana da matuƙar mahimmanci, idan canjin ya yi yawa don ya shafi aikin gani na murfin, wanda ke haifar da bambancin launi na nau'ikan samfura daban-daban a ƙarƙashin dabara ɗaya.

2. Girman kai

Girman barbashi a zahiri ma'aunin wakilci ne, masana'antun rufewa ba kasafai suke gano girman barbashi kai tsaye ba. Duk da haka, saboda sauran alamun kaolin da aka yi da calcined suna da alaƙa kai tsaye da girman barbashi, idan girman barbashi bai isa ba, ko kuma bai cancanta ba, za a nuna shi ta wasu alamomi. Ga masana'antar kaolin da aka yi da calcined, ma'aunin dubawa na samfurin da aka gama ya kamata ya zama -2 μm a kusan 80%. Tabbas, aikin samfuran da aka samar da kayan masarufi daban-daban zai bambanta, kuma idan sauran ma'auni sun cancanta, ana iya rage buƙatun girman barbashi.

Girman barbashi yana da matuƙar tasiri ne sakamakon lalacewar ma'adinan danye da zafin calcination. Ƙarfin lalacewa yana da alaƙa da ingancin ma'adinan danye, wanda galibi yana shafar girman barbashi na matakin kayan, kuma zafin calcination galibi yana shafar girman barbashi na foda bayan murhu. Don shafa calcination kaolin, matsakaicin zafin calcination (1000 ~ 1200℃), ana zaɓar mafi kyawun zafin calcination a cikin matakin amorphous wanda aka canza zuwa matakin silicon aluminum spinel, wanda ke samar da tsarin faɗaɗa ramuka, wanda ke haifar da haɓakar ramuka, kuma ƙimar gogewar samfurin tana da ƙasa kaɗan.

3. Ƙarfin rufewa

Ƙarfin rufewa shine mafi mahimmancin ma'aunin kaolin da aka yi da calcined. Mafi ƙarancin foda, mafi girman haɗin da aka samar a cikin murfin, haka nan ƙarfin refraction da haskakawar haske, musamman lokacin da girman barbashi yayi daidai da tsawon hasken da ake iya gani, yana da tasirin warwatsewa mafi ƙarfi, zai iya samar da mafi girman ƙarfin rufewa, idan ƙasa da wannan ƙimar, ƙarfin rufewa zai zama ƙarami saboda bambancin hasken.

Ga kaolin mai laushi sosai, ko za a iya warwatse shi gaba ɗaya a cikin murfin shi ma muhimmin abu ne da ke shafar ƙarfin rufe shi. Duk da cewa calcination yana inganta ƙarfin rufe kaolin a cikin murfin da aka yi da ruwa, ba shi da mahimmanci. A wasu lokuta, yana da sauƙin narkewa da samar da ƙananan ƙwayoyin cuta, amma yana sa ƙarfin rufewa ya ragu, kuma ba za a iya amfani da shi don rufewa kwata-kwata ba. Wata matsala ita ce calcination ƙasa da 1000℃ wani lokacin yana haifar da yanayin ja mai haske, wanda yake da matukar muni ga fararen launuka. 1050℃ da foda mai kyau.

4. Yaɗuwa

Masana'antar rufe fuska ta gida ta ce warwatsewa, kuma manufar iri ɗaya ce. Duk da cewa kaolin da aka yi wa calcined ya sha foda mai kyau, tare da matsakaicin girman barbashi na 1 μ m ko ƙasa da haka, a cikin fenti, a cikin ruwan inabi mai yawan danko, barbashin ba a raba su ba amma an haɗa su wuri ɗaya. Ikon kaolin da aka yi wa calcined don warwatsewa a cikin tsarin rufewa ana kiransa warwatsewa. Warwatsewar kaolin da aka yi wa calcined yana da kyau. Idan matakin niƙa ya cika buƙatun ƙarshe, ana iya warwatse shi a cikin tsarin rufewa.

Yaɗuwar kaolin mai ƙamshi yana da alaƙa da tasirin ƙarshe na niƙa. Idan akwai ƙwayoyin cuta 45 μm ko mafi girma a cikin tsarin sarrafa superfine, ba za a watsa su a cikin tsarin shafa ba. Bukatar wannan ma'aunin bai kai 45 μm ba, kuma ƙarami, mafi kyau. Idan yaɗuwar titanium dioxide zai iya kaiwa 25 μm, ya kamata a zaɓi wanda ya dace da matakin niƙa a matsayin 4 ko fiye.

Ragowar raga mai ratsa 5.325

Ragowar sieve mai kauri 325 muhimmin ma'auni ne, buƙatar shafa wannan ma'aunin shine <0.02%, kuma ƙaramin ya fi kyau. Sieve mai kauri 325 shima yana da alaƙa da tasirin ƙarshe na niƙa, ba ya buƙatar 45 μm ko manyan barbashi yayin sarrafa ultrafine. Wani abin da ke tasiri shine ƙazanta, haɗe da ƙazanta suna da tasiri mafi bayyana akan abun da ke cikin simintin 325.

6. Darajar shan mai

Darajar shan mai na kaolin mai ƙamshi shine 50g / 100g ~ 60g / 100g matsakaici ne, adadin shan mai ya yi yawa, ɗanɗanon rufewa da aka yi da wannan dabarar yana da girma, domin rage ɗanɗanon, adadin tushen fenti dole ne ya ƙara farashi; ƙimar shan mai ya yi ƙasa sosai, rufin da aka yi yana da sauƙin daidaitawa, kuma aikin buɗewa ba shi da kyau. Darajar shan mai na kaolin shine rarraba girman barbashi, porosity, takamaiman yankin saman, da nau'in barbashi. Girman barbashi ƙarami ne, takamaiman yankin saman ya fi girma, kuma ƙimar shan mai shine

7. Yawan yarjejeniyar

Darajar shan mai na kaolin mai ƙamshi shine 50g / 100g ~ 60g / 100g matsakaici ne, adadin shan mai ya yi yawa, ɗanɗanon shafa mai da aka yi da irin wannan dabarar yana da girma, domin rage ɗanɗanon, adadin tushen fenti dole ne ya ƙara farashi; ƙimar shan mai ya yi ƙasa sosai, rufin da aka yi yana da sauƙin daidaitawa, kuma aikin buɗewa ba shi da kyau. Darajar shan mai na kaolin shine rarraba girman barbashi, porosity, takamaiman yankin saman, da nau'in barbashi. Girman barbashi ƙarami ne, takamaiman yankin saman ya fi girma, kuma ƙimar shan mai ya fi girma.

8.pH ƙimar

Darajar pH tana nuna acid da alkalinity na kaolin da aka yi da calcine, kuma ƙimar pH ya kamata ta kasance tsakanin 6 da 8, kusan kusa da tsaka tsaki. PH na kaolin da aka yi da calcine da kansa tsaka tsaki ne, don haka ba a buƙatar gyaran PH a masana'antar rufewa.

9. Juriyar Yanayi

Bayan an yi fenti da fenti da kuma shafa fenti, fentin da ke cikin rana da ruwan sama zai canza launin rawaya, ya rasa haske da foda. Ikon pigments na tsayayya da waɗannan canje-canje ana kiransa juriyar yanayi. Kaolin da aka yi da calcined ba shi da wani ƙarfi na sinadarai a kan haske, don haka yana da kyakkyawan juriyar yanayi.

10. Sauran alamomi

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
