I. Cov khoom siv 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) lub sijhawm pib: lub sijhawm luv luv, rau kev hloov kho cov khoom siv rau tib lub sijhawm ntawm lub tshuab ziab khaub ncaws. (2) lub sij hawm ceev ceev: qhov no yog qhov ziab ntawm lub sij hawm, cov khoom nto evaporation ntawm cov dej, sab hauv tsuas yog txaus los ntxiv, yog li qhov saum npoo ntawm cov yeeb yaj kiab dej tseem nyob hauv, thiab khaws cia ntawm qhov ntub dej kub. .

I. Tshuab ziab khaub ncaws kom qhuav tus nqi

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

2. Kev ua kom qhuav

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

(2) lub sij hawm ceev ceev: qhov no yog lub sij hawm kom qhuav ^ ib lub sij hawm loj, cov khoom nto evaporation ntawm cov dej, sab hauv tsuas yog txaus los ntxiv, yog li qhov saum npoo ntawm cov yeeb yaj kiab dej tseem nyob hauv, thiab khaws cia ntawm qhov ntub dej kub.

(3) Deceleration ntawm ib lub sij hawm ntawm lub sij hawm: lub sij hawm no lub evaporation ntawm dej, lub sab hauv yuav tsis tau tag nrho replenished, yog li ntawd lub nto dej zaj duab xis pib rupture, qhov ziab ntawm tus nqi kuj pib qeeb, cov khoom ntawm lub point no yog. hu ua qhov tseem ceeb, cov dej uas muaj nyob rau lub sijhawm no, hu ua cov dej tseem ceeb.

(4) Deceleration ntawm theem ob: tsuas yog cov ntaub ntawv ntom ntom hauv 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 feem ntau yog nqa tawm nyob rau saum npoo, thiab cov zaj duab xis dej ntawm lub nto yog kiag li ploj mus nyob rau hauv lub thib ob lub sij hawm, yog li cov dej diffuses rau saum npoo nyob rau hauv daim ntawv ntawm cov dej vapor.

II. Cov yam ntxwv cuam tshuam rau tus nqi ntawm qhov ceev kom qhuav

1. qhov kub ntawm huab cua: yog tias qhov kub thiab txias, qhov diffusion ntawm hws dej evaporation tus nqi yog nce. 2. cov av noo: ntawm cov av qis, cov dej evaporation yuav loj dua.

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: qhov nrawm dua, qhov zoo dua qhov cuam tshuam ntawm huab hwm coj thiab hloov tshav kub.

4. Lub shrinkage thiab deg hardening: ob qhov tshwm sim no yuav cuam tshuam rau ziab.

III. Kev faib cov khoom siv ziab khaub ncaws

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

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