Hlau nruas yog ib lub hnab ntim thiab khoom siv thauj khoom. Cov hlau nruas yog siv los tuav ntau yam dej. Txhawm rau kom muaj kev nyab xeeb hauv tsheb thauj mus los, yuav tsum tau ua raws li qhov yuav tsum tau ua kom zoo. Thaum lub sealing tsis nruj, nws yuav ua rau peb cov khoom. Poob, yog li nws tseem ceeb kom nkag siab txog yam uas cuam tshuam rau qhov ceev ntawm qhov siab, uas tuaj yeem pab peb kom tsis txhob muaj cov teeb meem no. Qhov tseeb, thaum muaj ib qho teeb meem nrog lub nrig ntawm cov hlau nruas, peb yuav tsum xub paub qhov ua txhaum lawm, xws li: muaj ib qho teeb meem nrog lub sealing ntawm tej yam hlau nruas, los yog muaj teeb meem nrog sealing ntawm tag nrho cov khoom ntawm cov khoom, thiab yam tseem ceeb ntawm txoj kev sib tw ntawm cov hlau nruas yog cov nram qab no:
1. Cov hlau thooj tsis zoo. Feem ntau, qee cov lag luam tsis muab cov khoom siv khib nyiab pov tseg kom txo tau cov nqi ntawm cov khoom, uas ua rau poob qis rau qhov zoo ntawm raw cov ntaub ntawv, uas cuam tshuam qhov ceev nrig ntawm cov hlau nruas;
2, cov hlau phom khoom mis tsis yog kev ua haujlwm. Muaj ntau hom khoom siv los ua cov tshuaj muaj hlau nruas. Feem ntau cov ntaub ntawv siv tshuaj yog polyethylene thiab polypropylene. Cov ntaub ntawv thiab cov khoom siv ntxiv hauv cov khoom siv hlau cov yeeb nkab yog txawv, thiab cov khoom sib txawv ntawm cov khoom raw nyias txawv nyias. Qee cov ntaub ntawv muaj zog, qee cov ntaub ntawv Nws yog softer, thiab los txhim kho qhov nruj ntawm cov hlau nruas, nws yog qhov yuav tsum tau nkag siab txog cov khoom siv thiab muab kev ua si kom zoo. Cov kev faib ua feem thiab kev tsim ntawm cov ntaub ntawv tseem ceeb heev, uas yog ib qho tseem ceeb tshaj uas cuam tshuam txog qhov ceev nrig ntawm cov hlau nruas;
3. Cov hlau nrig yog tsis txaus. Qhov tsis muaj qhov tseeb ntawm cov pwm yuav cuam tshuam qhov haum ntawm lub hau hau thiab lub thoob. Lub precision ntawm lub puab kuj yog ib qho tseem ceeb heev uas cuam tshuam rau kev sib tsoo ntawm tshuaj yeeb tshuaj.
4. Cov khoom tsis tau poob deb. Nws yog feem ntau tsim nyog los ua haujlwm rau cov cuab yeej ua ntej yuav tsim khoom. Cov txom nyem commissioning tseem yuav cuam tshuam cov sealing ntawm cov hlau hlau nruas.
