warshad toosan oo Guilin Hongkaolin ah

Soo-saareyaasha qalabka shiidi ee Guilin HongchengWaxaan bartay in alaabada shiididda kaolin ee kalsiyum-ka ah inta badan loo isticmaalo warshadaha dahaarka, kaas oo loo isticmaalo buuxin rinjiga, dhinaca kalena uu door ka ciyaaro buuxinta jirka, dhanka kalena uu leeyahay awood dabool qalalan. Haddaba, waa maxay shuruudaha tusmada ee alaabada shiididda kaolin ee kalsiyum-ka ah?

Tusmooyinka wax soo saarka ee kaolin-ka calcined ee dahaarka waxaa inta badan ka mid ah caddaanka, cabbirka walxaha, xoogga daboolka, kala firdhinta, haraaga shaandhada 325 mesh, qiimaha nuugista saliidda, mugga dhigaalka, qiimaha pH, iska caabbinta cimilada iyo wixii la mid ah:

1. Shahaadada Cad

Caddaanku waa tusmada koowaad ee kaolin-ka kalsiyum-ka, marka uu sarreeyo ayaa ka sii fiican. Rinjiga midabka waxaa sidoo kale laga sameeyay rinji cad oo ah rinjiga salka iyo midabka hooyada. Caddaanku waa inuu ugu yaraan ka weynaadaa 90%, soosaarayaasha qaar xitaa waxay u baahan yihiin in ka badan 93%. Xasiloonida heerka cad aad ayey muhiim u tahay, haddii isbeddelka uu aad u weyn yahay si uu u saameeyo waxqabadka indhaha ee dahaarka, taasoo keenta kala duwanaanshaha midabka ee dufcadaha kala duwan ee alaabada oo hoos yimaada qaacidada isku midka ah.

2.Granularity

Cabbirka walxaha dhab ahaantii waa tusmada matalaadda, soosaarayaasha dahaarka leh si dhif ah ayay si toos ah u ogaadaan cabbirka walxaha. Si kastaba ha ahaatee, sababtoo ah tilmaamayaasha kale ee kaolin-ka kalsiyumku si toos ah ayay ula xiriiraan cabbirka walxaha, haddii cabbirka walxaha uusan ku filnayn, ama aan u qalmin, waxaa lagu muujin doonaa tilmaamayaal kale. Soo saaraha kaolin-ka kalsiyumku, tusmada kormeerka ee badeecada la dhammeeyay waa inay ahaataa -2 μm qiyaastii 80%. Dabcan, waxqabadka alaabada ay soo saaraan walxaha ceeriin ee kala duwan way kala duwanaan doonaan, haddii tilmaamayaasha kale ay u qalmaan, shuruudaha cabbirka walxaha ayaa sidoo kale la dhimi karaa.

Cabbirka walxaha waxaa inta badan saameeya xirashada macdanta ceeriin iyo heerkulka kaalshiyamka. Awoodda xirashada waxaa lagu go'aamiyaa tayada macdanta ceeriin, taas oo inta badan saameysa cabbirka walxaha marxaladda ceeriin, heerkulka kaalshiyamkana wuxuu inta badan saameeyaa cabbirka walxaha budada ka dib foornada. Si loogu dahaadho kaalshiyamka kaolin, kaalshiyamka heerkulka dhexdhexaadka ah (1000 ~ 1200℃), heerkulka kaalshiyamka ugu fiican waxaa lagu doortaa marxaladda aan qaab-dhismeedka lahayn oo hadda loo beddelay wejiga spinel aluminium silicon, kaas oo soo saara qaab-dhismeedka ballaarinta daloolada, taasoo keenta horumarinta daloolada, qiimaha xoqitaanka ee badeecadduna waa mid hooseeya.

3. Dabool xoog

Awoodda daboolku waa tusmada ugu muhiimsan ee kaolin-ka calcined. Inta uu budada khafiifsan yahay, ayaa isku-dhafka badan ee dahaarka ku samaysma, ayaa sii xoogaysanaya dib-u-soo-celinta iyo milicsiga iftiinka, gaar ahaan marka cabbirka walxaha uu la mid yahay hirarka iftiinka la arki karo, wuxuu leeyahay saameynta kala firdhinta ugu xooggan, wuxuuna soo saari karaa xoogga daboolida ugu weyn, marka qiimahan ka yar yahay, xoogga daboolida ayaa yaraan doona sababtoo ah kala-firdhinta iftiinka.

Kaolin aad u fiican, in si buuxda loogu kala firdhin karo dahaarka sidoo kale waa arrin muhiim ah oo saameysa awooddeeda daboolista. In kasta oo kaalshiyamku uu hagaajiyo awoodda daboolista ee kaolin ee dahaarka biyaha ku salaysan, haddana ma aha mid muhiim ah. Xaaladaha qaarkood, way fududahay in la sifeeyo oo la sameeyo walxo qallafsan, laakiin waxay ka dhigtaa xoogga daboolista mid yaraada, mana loo isticmaali karo dahaarka gabi ahaanba. Dhibaato kale ayaa ah in kaalshiyamku ka hooseeyo 1000℃ mararka qaarkood uu soo saaro marxalad casaan khafiif ah, taas oo aad ugu xun midabada cad. 1050℃ iyo budada superfine.

4. Kala firdhisnaanta

Warshadaha dahaarka gudaha ayaa sheegay kala firdhinta, fikradduna waa isku mid. Inkasta oo kaolin-ka calcined-ka lagu sameeyay uu mariyay budo aad u fiican, oo leh celcelis ahaan cabbirka walxaha 1 μm ama ka yar, rinjiga, khamriga waalidka ee viscosity-ga sareeya, walxaha ma kala soocaan laakiin waa la isku ururiyay. Awoodda kaolin-ka calcined-ka lagu sameeyay uu ku kala firdhi karo nidaamka dahaarka waxaa loo yaqaan kala firdhinta. Kala firdhinta kaolin-ka calcined-ka ah waa mid wanaagsan. Haddii heerka shiididdu uu buuxiyo shuruudaha kama dambaysta ah, waxaa lagu kala firdhi karaa nidaamka dahaarka.

Kala firdhinta kaolin-ka calcined waxay la xiriirtaa saameynta ugu dambeysa ee shiididda. Haddii 45 μm ama walxo ka weyn ay ku jiraan habka farsamaynta superfine, laguma kala firdhin doono nidaamka dahaarka. Shuruudaha loogu talagalay tusmadan waa ka yar yihiin 45 μm, kan yarna, wuu ka sii fiican yahay. Haddii kala firdhinta titanium dioxide ay gaari karto 25 μm, oo u dhiganta heerka shiididda waa in loo doortaa 4 ama ka badan.

5.325 haraaga shaandhada shaadhka

Hadhaaga shaandhada 325 mesh waa tusmo muhiim ah, shuruudaha lagu dahaadhay tusmadan waa <0.02%, kan yarna wuu ka sii fiican yahay. shaandhada 325 mesh sidoo kale waxay inta badan la xiriirtaa saameynta ugu dambeysa ee shiididda, iyadoo aan u baahnayn 45 μm ama walxo ka weyn inta lagu jiro farsamaynta ultrafine. Arrin kale oo saameyn leh waa wasakhda, oo lagu qasay wasakhda ayaa leh saameynta ugu cad ee ku saabsan waxa ku jira baaritaanka 325 mesh.

6. Qiimaha nuugista saliidda

Qiimaha nuugista saliidda ee kaolin-ka kalsiyumku waa 50g / 100g ~ 60g / 100g waa dhexdhexaad, xaddiga nuugista saliidda aad ayuu u sarreeyaa, dheellitirka dahaarka ee lagu sameeyay qaacidada isku midka ah waa weyn yahay, si loo yareeyo nuugista, xaddiga saldhigga rinjiga waa inuu kordhiyaa kharashka; qiimaha nuugista saliidda aad ayuu u hooseeyaa, dahaarka la sameeyay waa mid si fudud loo dejin karo, waxqabadka furitaankana ma fiicna. Qiimaha nuugista saliidda ee kaolin waa qaybinta cabbirka walxaha, daloolka, aagga dusha sare ee gaarka ah, iyo nooca badarka ee walxaha. Cabbirka walxaha waa yar yahay, aagga dusha sare ee gaarka ah waa ka weyn yahay, qiimaha nuugista saliiddana waa

7. Mugga dejinta

Qiimaha nuugista saliidda ee kaolin-ka kalsiyumku waa 50g / 100g ~ 60g / 100g waa dhexdhexaad, xaddiga nuugista saliidda aad ayuu u sarreeyaa, dheellitirka dahaarka ee lagu sameeyay qaacidada isku midka ah waa weyn yahay, si loo yareeyo dheellitirka, xaddiga saldhigga rinjiga waa inuu kordhiyaa kharashka; qiimaha nuugista saliidda aad ayuu u hooseeyaa, dahaarka la sameeyay waa mid si fudud loo dejin karo, waxqabadka furitaankana ma fiicna. Qiimaha nuugista saliidda ee kaolin waa qaybinta cabbirka walxaha, daloolka, aagga dusha sare ee gaarka ah, iyo nooca badarka ee walxaha. Cabbirka walxaha waa yar yahay, aagga dusha sare ee gaarka ah waa weyn yahay, qiimaha nuugista saliiddana waa ka sarreeyaa.

Qiimaha 8.pH

Qiimaha pH wuxuu ka tarjumayaa aashitada iyo alkalinity-ga kaolin-ka la qalajiyey, qiimaha pH-kuna waa inuu u dhexeeyaa 6 iyo 8, asal ahaanna wuxuu u dhow yahay dhexdhexaad. PH-ga kaolin-ka la qalajiyey laftiisu waa dhexdhexaad, sidaa darteed wax-ka-beddelka PH-ga looma baahna warshadaha dahaarka.

9. Iska caabbinta cimilada

Ka dib marka midabka laga sameeyo rinji iyo daub, rinjiga oo dhex mara qorraxda iyo roobka wuxuu isu beddeli doonaa jaalle, wuxuu lumin doonaa iftiinka iyo budada. Awoodda midabyada ay u leeyihiin inay iska caabiyaan isbeddelladan waxaa loo yaqaan iska caabbinta cimilada. Kaolin-ka Calcined ma laha firfircooni kiimiko oo xooggan oo ku saabsan iftiinka, sidaas darteed wuxuu leeyahay iska caabbinta cimilada oo wanaagsan.

10. Tilmaamayaal kale

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
