Kho lub taub hau tuag ntawm lub tshuab cua tshuab extrusion yog ib kauj ruam tseem ceeb hauv kev ua kom cov khoom zoo ntawm - cov yas yeeb yaj kiab zoo. Mastering qee qhov kev hloov kho tuaj yeem tsis tsuas yog txhim kho kev tsim khoom tab sis kuj ua kom cov khoom zoo. Nov yog qee cov tswv yim qhia txog kev kho lub taub hau tuag ntawm lub tshuab cua tshuab extrusion:
1. Temperature Control: Qhov kub thiab txias ntawm lub taub hau tuag yog qhov tseem ceeb. Nws yuav tsum tau teem raws li hom thiab thickness ntawm cov yas raw khoom siv thiab cov khoom xav tau kev ua tau zoo. Qhov kub ntau dhau yuav ua rau cov yas yaj sai heev, ua npuas dej; thaum qhov kub tsis txaus yuav ua rau cov yas tsis sib xws, cuam tshuam rau qhov sib xws thiab pob tshab ntawm zaj duab xis.
2. Cua Ceev thiab Airflow Kho: Cov huab cua ceev thiab airflow nyob rau hauv lub tshuab cua tshuab extrusion yog ib qho tseem ceeb rau kev tsim zaj duab xis thiab zoo. Tsim nyog huab cua ceev kom zoo ib yam stretching ntawm cov yas zaj duab xis, thaum airflow txiav txim lub thickness thiab stability. Kev hloov kho yuav tsum tau ua kom zoo-tuned raws li lub xeev molten ntawm cov yas thiab cov yeeb yaj kiab uas xav tau.
3. Die Head Gap Adjustment: Qhov luaj li cas ntawm lub taub hau tuag qhov sib txawv ncaj qha cuam tshuam rau cov yeeb yaj kiab tuab. Qhov sib txawv loj heev tuaj yeem ua rau cov yeeb yaj kiab uas nyias dhau, thaum qhov sib txawv me me yuav ua rau cov yeeb yaj kiab tuab dhau los yog ua rau txhaws. Qhov sib txawv yuav tsum tau kho kom haum raws li qhov xav tau ntawm zaj duab xis thickness thiab hnav lub taub hau tuag.
4. Kev tu thiab tu: tsis tu ncua ntxuav lub taub hau tuag kom tshem tawm cov khoom seem ntawm cov yas thiab cov impurities, ua kom nws flatness thiab thermal conductivity. Nyob rau tib lub sijhawm, tshawb xyuas lub taub hau tuag rau kev hnav thiab hloov cov khoom hnav hnyav sai sai kom ntseeg tau tias cov yeeb yaj kiab ruaj khov.
5. Cov txheej txheem kev khiav hauj lwm: Thaum lub sij hawm hloov kho, ua tib zoo saib cov kev hloov ntawm cov yeeb yaj kiab thiab kev ntxhib los mos, kho qhov cuam tshuam raws li qhov xav tau. Cov neeg ua haujlwm yuav tsum paub txog cov yam ntxwv ntawm kev ua haujlwm ntawm lub tshuab cua tshuab thiab ua raws li cov txheej txheem ua haujlwm kom ntseeg tau tias kev ruaj ntseg thiab kev nyab xeeb ntawm cov txheej txheem tsim khoom.
Los ntawm kev paub txog cov tshuab tshuab zaj duab xis tuag lub taub hau hloov cov lus qhia thiab sib txuas nrog cov kev ua haujlwm zoo, kev tsim khoom thiab cov khoom zoo ntawm lub tshuab cua tshuab tuaj yeem txhim kho tsis tu ncua, ua tau raws li kev xav tau ntawm kev lag luam.
