Hnav cov kev daws teeb meem rau loj extruders

Vim hais tias lub extruder yog ua los ntawm cov hlau thiab muaj hardness siab, nws yuav raug kev co, kev cuam tshuam thiab lwm yam sib xyaw zog thaum lub sij hawm tsim khoom thiab kev khiav hauj lwm, ua rau muaj qhov sib txawv ntawm cov khoom thiab ua rau hnav. Cov kev kho ib txwm muaj xws li surfacing, thermal spraying, txhuam vuam, thiab lwm yam, tab sis ob peb txoj kev muaj qee qhov tsis zoo: surfacing yuav ua rau saum npoo mus txog qhov kub thiab txias, ua rau deformation lossis tawg ntawm qhov, cuam tshuam qhov tseeb thiab qhov qub. siv. Thaum mob hnyav, nws yuav ua rau tawg; Txawm hais tias kev hloov pauv ntawm txhuam tsis muaj qhov cuam tshuam thermal, lub thickness ntawm cov txheej txheem hloov tsis tuaj yeem tuab heev, ua rau muaj kuab paug loj heev thiab txwv nws daim ntawv thov.
Nws txoj kev ua tau zoo thiab muaj peev xwm ua tau txhua lub sijhawm tuaj yeem ua tau raws li qhov xav tau ntawm kev siv thiab raug tom qab kho. Nws tseem tuaj yeem txo qhov cuam tshuam thiab kev vibration cov cuab yeej siv tau thaum lub sijhawm ua haujlwm thiab txuas ntxiv nws lub neej kev pabcuam. Vim tias cov khoom siv yog qhov kev sib raug zoo, thaum lub zog sab nraud cuam tshuam rau cov khoom siv, cov khoom yuav deform kom nqus cov quab yuam sab nraud, thiab nthuav dav thiab cog lus nrog kev nthuav dav thiab kev cog lus ntawm cov kabmob lossis lwm yam khoom, ib txwm tswj kom nruj nruj nrog. cov khoom siv, txo txoj kev hnav.
Raws li kev hnav thiab tsim kua muag ntawm cov extruders loj, "moulds" lossis "fitting parts" kuj tuaj yeem siv los kho cov khoom puas ntawm qhov chaw, zam qhov kev tshem tawm tag nrho ntawm cov cuab yeej, kom ntseeg tau qhov sib txuam ntawm qhov chaw mus rau qhov siab tshaj plaws, thiab ua tau raws li kev tsim khoom thiab kev ua haujlwm ntawm cov khoom siv.
