Vaj huaim npawg rau kev tshuab ntxuav cov duab los ntawm PA66 | POLYWELL

Daim ntawv hlau rau kev tshuab hlau yog qhov tseem ceeb hauv kev tsav ntaus thiab kev tsav hlau ua rau, vim tias daim ntawv hlau yog qhov khoom siv los muab rau tus cwj mem rau cov khoom tshuab hlau. Kev xaiv daim ntawv hlau rau daim ntawv hlau yog txiav txim los ntawm cov lwm yam xav tau rau kev tiv thaiv kev siv, kev kho, kev nyab xeeb hauv zog tshaj plaws, thiab txawm tias kev tiv thaiv kev puas tsuaj. Rau kev tsav ntaus, tshpecially rau cov ntaus tshwj xeeb zoo li PA66 ntaus nrog cov ntaus hlau siv rau kev tiv thaiv kub, cov daim ntawv hlau feem ntau tsim los ntawm cov hlau siv khoom zoo. AISI P20 thiab H13 (hlau Chromium-Hot-Work) yog qhov feem ntau xaiv. H13 muaj qhov tseem ceeb heev rau nws cov kev nyab xeeb zoo, kev tiv thaiv kev siv, thiab kev nyab xeeb, uas yog qhov tseem ceeb rau kev tiv thaiv kev puas tsuaj ntawm cov khoom siv nrog cov ntaus hlau. Cov teeb meem thiab cov chaw tshuab hlau feem ntau yog txiav txim siab kom muaj qhov nyab xeeb siab, feem ntau ntawm 48-52 HRC. Tom qab khiav, cov chaw no yog kho kom ncua siab, feem ntau ncua siab 8-16 micro-inch, kom txo kev sib thaub thiab tiv thaiv kev puas tsuaj uas tuaj yeem cuam tshuam rau cov khoom tshuab hlau thiab cov chaw puas tsuaj. Rau kev tsav hlau, uas muaj ntau dua zog thiab kub dua, cov hlau uas muaj nitrogen zoo li H13 yog qhov feem ntau, thiab kev ntxig nitrogen yog qhov tsim qhov chaw nyab xeeb tshaj plaws thiab tiv thaiv kev siv. Qhov tseeb, qhov nyab xeeb hauv kub, thiab qhov chaw ncua siab ntawm daim ntawv hlau rau kev tsav hlau yog qhov tseem ceeb heev, vim tias txhua qhov siv lossis qhov poob yuav raug tshuab rau txhua meter ntawm daim tshuab hlau, cuam tshuam rau qhov ntev, qhov chaw ncua siab, thiab thaum kawg yog qhov kev ua haujlwm.
