Yog hais tias, thaum lub sij hawm machining txheej txheem, cov khoom tseem ceeb raug tshem tawm, annealing yog pom zoo kom txo tau machined-nyob rau hauv-kev nyuaj siab thiab txo qhov ua tau ntawm ua ntej ib feem tsis ua hauj lwm.

Yog vim li cas Annealing Plastics
Tag nrho cov khoom lag luam extruded yas yog compressed los ntawm qhov profile tuag thaum extruded. Lub compression uas tshwm sim nyob rau hauv cov khoom yog tsis relieved vim hais tias cov yas "tsim" sai li sai tau raws li nws tawm ntawm lub tuag thiab nws tseem nyob rau hauv no compressed los yog heev stressed lub xeev. Qhov kev ntxhov siab siab siab no yuav ua rau plaub qhov teeb meem yog tias tsis hais txog:
- Cov ntaub ntawv yuav zoo li warp los yog distort
- Lub cev lub cev yuav txawv dua li cov ntaub ntawv luam tawm (feem ntau qis dua)
- Cov khoom yuav tawg
- Ua tiav qhov loj me tuaj yeem hloov pauv
Yuav kom tshem tawm cov teeb meem no extruded khoom yog annealed. Annealing yog txheej txheem kev ntxhov siab, uas tshwm sim thaum cov khoom raug tshav kub (cua lossis kua) saum nws cov iav hloov pauv, uas tso cai rau cov khoom "decompress" rov qab mus rau lub xeev so. Annealing yog ib qho tseem ceeb yog tias koj xav tau qhov zoo, ua tiav ib feem ntawm koj cov khoom zoo.
Annealing/Stress Relieving Procedure rau Acetal
- Muab cov khoom tso rau hauv qhov cub cua uas cua tuaj yeem ncig lawv
- Kub qhov cub kom 300 degrees Fahrenheit ntawm qhov siab tshaj plaws ntawm 20 degrees Fahrenheit ib teev.
- Tuav qhov cub kub ntawm 300 degrees Fahrenheit 30 feeb ntxiv rau 15 feeb rau txhua 1/8 "ntawm ntu
- Txias qhov cub kom 150 degrees Fahrenheit tshaj 15 teev nrog qhov txias siab tshaj plaws ntawm 10 degrees Fahrenheit ib teev.
- Tua qhov cub thiab cia kom txias rau chav tsev kub ua ntej tshem cov khoom
