Kev xaiv pwm

Kev xaiv ntawm cov pwm xav tau kom tau raws li peb lub hauv paus. Cov pwm ua tau raws li kev ua haujlwm ntawm kev ua haujlwm ntawm kev hnav tsis kam, tawv tawv, thiab lwm yam.

Folding mob yuav tsum
1, hnav tsis kam

Thaum cov voos voos yog plastically denatured hauv cov pwm kab noj hniav, nws ntws thiab swb raws cov kab noj hniav, ua rau muaj kev sib txhuam hnyav ntawm qhov chaw kab noj hniav thiab qhov chaw khoob, uas ua rau kom lub pwm tsis tuaj yeem vim hnav. Yog li ntawd, cov hnav tsis kam ntawm cov khoom yog ib qho ntawm cov yooj yim thiab tseem ceeb ntawm cov pwm.

Hardness yog qhov tseem ceeb cuam tshuam rau hnav tsis kam. Feem ntau, qhov hnyav dua ntawm cov pwm ua ib feem, hnav me dua, thiab qhov zoo dua qhov hnav tsis kam. Ntxiv rau, cov hnav tsis kam kuj tseem muaj feem xyuam rau hom, qhov ntau, cov qauv, qhov loj me thiab kev faib tawm ntawm carbides hauv cov khoom siv.

2. Lub zog tawv

Feem ntau ntawm cov haujlwm ua haujlwm ntawm cov pwm yog qhov tsis zoo, thiab qee qhov feem ntau cuam tshuam los ntawm qhov kev cuam tshuam loj, uas ua rau muaj pob tawg. Txhawm rau tiv thaiv cov pwm ntu ntawm kev tawg tam sim ntawd thaum ua haujlwm, lub pwm yuav tsum muaj qhov muaj zog thiab tawv.

Lub zog hnyav ntawm cov pwm nyob ntawm lub ntsiab lus carbon ntau, qhov loj me thiab microstructure ntawm cov khoom.

3. Lub cev qia tawv dhau kev ua rau zoo

Thaum lub sijhawm ua haujlwm ntawm cov pwm, nyob rau hauv cov txiaj ntsig ntev ntev ntawm kev cuam tshuam ntawm cyclic, nkees nkees feem ntau ua rau. Daim ntawv muaj lub zog me ntau qhov kev cuam tshuam kev nkees pob txha, lub cev nyhav ua rau qaug zog tuaj yeem tiv thaiv kev nkees nkees thiab ua rau lub cev puas tsuaj.

Lub zog qia ntawm cov pwm ua feem ntau nyob ntawm nws lub zog, tawv, tawv, thiab cov nqi ntawm cov lus qhia hauv cov khoom siv.

4. Kev ua haujlwm kub

Thaum ua haujlwm kub ntawm pwm pwm siab dua, lub hardness thiab lub zog qis dua, uas ua rau kev hnav thaum ntxov ua pwm lossis yas deformation thiab tsis ua haujlwm. Yog li ntawd, cov khoom siv pwm yuav tsum muaj qhov siab los tiv thaiv kev kub ntxhov kom paub meej tias lub pwm muaj lub siab tawv thiab lub zog ntawm qhov kub ua haujlwm.

5. Kev tiv thaiv rau qhov txias txias thiab kub ua kom zoo siab

Qee qhov pwm nyob hauv lub xeev ntawm kev rov ua kom sov thiab cua txias thaum lub sijhawm ua haujlwm, ua rau lub ntsej muag ntawm cov kab noj hniav ua rau lub luag haujlwm thiab lub siab ua kom muaj kev ntxhov siab, ua rau muaj kev tawg thiab ua kom lub ntsej muag, ua kom muaj kev sib txhuam, ua rau cov yas tsis zoo, thiab txo qhov tseeb , dhau li ntawd ua rau cov pwm tsis ua haujlwm. Nkees kub thiab txias yog ib qho ntawm cov qauv tseem ceeb ntawm kev ua haujlwm kub tuag tsis ua haujlwm. Nws yuav tsum muaj qhov ua tau zoo rau qhov txias txias thiab kub nkees.

6. Corrosion tsis kam

Qee yam pwm, xws li yas pwm, thaum ua haujlwm, vim tias muaj cov tshuaj chlorine, fluorine thiab lwm yam khoom nyob hauv cov yas, tom qab tshav kub, HCI, HF thiab lwm cov roj ntsha muaj zog raug daws teeb meem, yaig ntawm qhov pwm ntawm cov kab noj hniav, nce nws saum npoo roughness thiab aggravating hnav thiab kua muag.
