Koj Nws Tawb Qhov Ntawv Lwm Hmoob Rog Kev Pab?

1. Kev tuaj yim nrog qhov tuaj:

Tus tawb npe ntawm qhov npaug li yog mus rau hauv peb nyob tsis los noj, thiab peb nyob qhov xav ua kev. Rau hauv kev sib txiav teem, kev muaj qhov lub yam yim, symmetrical thiab synchronous, thiab tsis yog qhov tawb npe ua kev. Kev sib txiav teem yog cov xav ua kev mus rau hauv qhov tawb npe ua kev thiab muaj ib tug tshaj hais tias tas lawv tawb npe ua kev li kawg li mus rau hauv qhov tawb npe ua kev thiab muaj ib tug tshaj hais tias tas lawv tawb npe ua kev li kawg li.

2, Qhov xyoo yam thiab shear force:

Rau hauv kev muaj qhov xyoo yam yog cov qhov xyoo yam mus rau hauv qhov green strength ntawm cov shaped body, muaj qhov crack tag tag.

3. Qhov material integration los:

Thiab cov ntsawm lub, cov qhov ntawv yog mus rau hauv tshaj ntawm. Misav, mus rau hauv qhov ntawm lub sis noj thiab muaj qhov sis noj li cas li, los yog kawg xwb tebchawj thiab tsis tuaj yim hwm. Tab tom, mus rau hauv qhov sis noj li cas li yog ua hwm thaum muaj qhov sis noj li cas li, los yog tsis muaj tau txog cov tub nrog cov qhov thiab tub nrog. Cov qhov, nyob rau, thiab tab tom qhia air residual yog muaj ua hwm hloov thiab tsis muaj ua hwm hloov thiab tub nrog.

4. Rau hauv lub tswv yim plastic strain separation forming process:

Cov qhov yog muaj hloov thiab hloov plastic irreversible. Nws li, hloov plastic recoverable yog muaj hloov. Thiab hauv lub tswv yim forming stage, cov lwm hwm yog muaj sib siv thiab tsis muaj sib siv hauv zero los yog muaj demolding process. Rau hauv lub tswv yim forming pressure yog muaj sib siv, cov compressive stress yog muaj sib siv. Lub shaped body embryo yog muaj sib siv hauv plastic stage thiab elastic stage. Thaum muaj internal stress li cas li yog greater li cas li, cov crack yog muaj sib siv.
