Cov cuab yeej ziab kom qhuav qhov ntsuas qhov cuam tshuam cuam tshuam thiab kev faib cov cuab yeej ziab khaub ncaws

I. Cov cuab yeej ziab kom qhuav tus nqi 1. Cov khoom siv ziab kom qhuav tus nqi

1. Chav tsev lub sij hawm thiab chav tsev, qhov hnyav ntawm cov khoom poob, hu ua tus nqi ziab.

2. txheej txheem ziab

(1) thaum pib ntawm lub sijhawm: lub sijhawm luv luv, rau cov khoom siv yuav raug hloov kho rau tib lub sijhawm nrog lub tshuab ziab khaub ncaws.

(2) Lub sijhawm ceev ceev: qhov no yog qhov ziab ntawm lub sijhawm, cov khoom siv evaporation ntawm cov dej, sab hauv tsuas yog txaus los ntxiv, yog li cov dej saum npoo av.

(3) Deceleration ntawm ib lub sij hawm: nyob rau lub sij hawm no ntawm evaporation ntawm dej, lub internal tsis tuaj yeem rov qab tag nrho, yog li qhov saum npoo ntawm cov yeeb yaj kiab dej pib tawg, qhov ziab pib qeeb, cov khoom hu ua qhov pib ntawm qhov taw tes, cov dej muaj nyob rau ntawm qhov chaw no, hu ua cov dej tseem ceeb.

(4) Deceleration ntawm theem ob: tsuas yog cov ntaub ntawv ntom ntom nyob rau theem no, vim tias cov dej tsis yooj yim tuaj; tab sis cov khoom ntxeem tau tsis yog. Cov evaporation ntawm cov dej nyob rau hauv thawj lub sij hawm yog feem ntau yog nqa tawm nyob rau hauv lub nto, dej zaj duab xis nyob rau saum npoo ntawm lub thib ob lub sij hawm yog kiag li ploj mus, yog li cov dej yog diffused rau saum npoo nyob rau hauv daim ntawv ntawm dej vapor.

II. Yam cuam tshuam rau tus nqi ntawm qhov ceev kom qhuav

1. Huab cua kub: Yog tias qhov kub thiab txias nce, tus nqi diffusion thiab tus nqi ntawm evaporation ntawm cov dej yog nce. 2.

2. Cov av noo: ntawm cov av noo qis, qhov evaporation ntawm cov dej yuav loj dua. 3.

3. Kev tshaj tawm ntawm huab cua khiav: qhov nrawm dua, qhov zoo dua qhov cuam tshuam ntawm huab cua thiab cua sov hloov.

4. shrinkage thiab deg hardening: ob qho tib si phenomena cuam tshuam rau ziab.

III. Kev faib cov khoom siv ziab khaub ncaws

Cov dej ntau dhau yuav tsum tau muab tshem tawm kom deb li deb tau ua ntej cov khoom nkag mus rau hauv cov khoom siv.

1. Cov tshuab ziab khaub ncaws rau cov khib nyiab thiab pastes

(1) Phaj tshuab ziab khaub ncaws

(2) Sieve thauj tshuab ziab khaub ncaws

(3) Rotary tshuab ziab khaub ncaws

(4) Screw transporter tshuab ziab khaub ncaws

(5) Lub tshuab ziab khaub ncaws

(6) Lub tshuab ziab khaub ncaws

(7) Lub tshuab ziab khaub ncaws nrawm nrawm

(8) Lub tog raj kheej tshuab ziab khaub ncaws

2. Kev daws thiab dej slurry siv thermal evaporation kom tiav ziab

(1) Lub tshuab ziab khaub ncaws

(2) Lub tshuab ziab khaub ncaws
