Vim li cas kuv thiaj xav tau lub hauv paus?

Kev tsim kho ncej muaj ntau yam zoo dua lwm txoj kev tsim kho:

  • kwv nqi ntawm cov khoom siv hauv tsev;
  • nrawm ntawm kev tsim kho (koj tuaj yeem tsim lub tsev zoo puv hauv lub sijhawm luv tshaj plaws - hauv ib hlis nkaus xwb);
  • muaj peev xwm tsim kom tsis tu ncua, txawm hais tias huab cua zoo li cas, txawm tias nws los daus thiab los nag;
  • cov tsev zoo li no yog lub teeb yuag, yog li tsis muaj cov txheej txheem shrinkage ua rau tawg ntawm phab ntsa thiab partitions ntawm cov hlau ncej;
  • muaj sijhawm los tsim lub tsev ntawm koj tus kheej, rautsuas yog xav tau kev pab luv luv los ntawm ob peb tus neeg (tej zaum cov neeg hauv tsev neeg).

Main flaws

Ua ntej koj pib tsim, koj yuav tsum ntsuas txhua qhov zoo thiab qhov tsis zoo ntawm ib qho kev siv tshuab. Lub tsev thav duab muaj ntau qhov zoo, tab sis kuj muaj qhov tsis zoo. Yog li, nws tsim yog txuam nrog ib tug xov tooj ntawm complex xam uas yog heev nyuaj rau nqa tawm ntawm koj tus kheej, tsis yog ib tug pej xeem engineer thiab tsis muaj kev txawj ntse tshwj xeeb. Kev ua yuam kev hauv kev suav ntawm cov khoom thauj thiab kev xaiv tsis raug ntawm qhov profile lossis lub peev xwm ntawm kev txhawb nqa yog fraught nrog kev puas tsuaj loj.

Cov khoom siv profile yog, raws li txoj cai, zoo tib yam hlau, uas tsis muaj alloying ntsiab (chromium, nickel, thiab lwm yam). Cov khoom zoo li no yog qhov pheej yig tshaj. Tab sis ntawm qhov kub tsis zoo, lub peev xwm ntawm cov qauv no poob qis heev (ib qho khoom ntawm qhov hu ua txias brittleness). Yog li ntawd, nyob rau hauv tej yam kev mob ntawm huab cua txias, xws li ib tug ncej yuav tsum tsis txhob siv.

Qhov tsis zoo ntawm cov khoom siv no kuj cuam tshuam rau qhov kub thiab txias, uas tuaj yeem tshwm sim los ntawm hluav taws. Thaum tshav kub kub, cov hlau zoo tib yam poob nws elasticity thiab lub zog, thiab qhov no tuaj yeem ua rau lub tsev tawg.

Hlau, zoo li cov khoom siv hlau, muaj cov thermal conductivity zoo heev, yog li cov hlau ncej ntawm lub tsev absorbs thiab tshem tawm cov cua sov rau sab nraud. Yog li ntawd, kev rwb thaiv tsev ntawm cov qauv zoo li no yuav tsum tau them nqi siab rau cov khoom siv thiab kev ua haujlwm. Qhov no yog lwm qhov tsis zoo uas yuav tsum tau them sai sai rau, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntawm peb lub caij ntuj no hnyav thiab cov nqi siab raulub cev muaj zog.
