Raws li kev ntim khoom siv feem ntau, cov thawv ntim khoom muaj cov txiaj ntsig zoo ntawm daim ntawv thov thiab lawv cov txheej txheem rov ua dua tshiab kuj tseem paub tab. Koj tuaj yeem tshawb xyuas cov lus qhia luv luv rau kev rov ua dua ntawm cov thawv ntim khoom (tonbag). General ton hnab / thawv ntim feem ntau yog ua los ntawm polypropylene (PP), thiab lawv qhov tsis zoo tshaj plaws yog qhov cuam tshuam tsis zoo rau ib puag ncig. Tshwj xeeb tshaj yog thaum nws tsuas yog siv ib zaug thiab tom qab ntawd raug kho raws li pov tseg thiab muab tso rau hauv qhov chaw pov tseg. Hauv kev lag luam nyob sab Europe thiab Asmeskas, raws li cov tuam txhab them nyiaj rau kev ruaj khov thiab kev tiv thaiv ib puag ncig, ntxiv rau kev rov ua dua tshiab raws li cov khoom siv rov ua dua tshiab, cov hnab ntim khoom hnyav / lub thawv ntim kuj tseem tuaj yeem tsim kho tshiab thiab rov siv dua thaum ua kom muaj kev ntseeg siab 5 -6 zaug thaum txo nqi rau lub lag luam, nws kuj tseem txo cov pa phem ib puag ncig.
Tam sim no cia peb saib seb yuav ua li cas cov hnab ntim ntim / thawv ntim tau siv dua thiab rov siv dua. Cia peb saib seb nws feem ntau ua haujlwm li cas hauv kev lag luam thoob ntiaj teb tsim. Cov ntsiab lus suav nrog cov txheej txheem hauv qab no:
1. Rov ua dua thiab teeb tsa lub hnab siv thiab thauj lawv rov qab mus rau qhov chaw tshiab tshiab kom zoo ib yam;
2. Luam theej duab thiab sau npe cov hnab ntim khoom siv rov ua dua tshiab thiab nkag mus rau hauv cov chaw muag khoom khaws cia los sau lawv cov kev siv lub neej;
3. Yog hais tias lub hnab yog lined, lub hauv ob sab phlu yuav tsum tau muab tshem tawm thiab yuav tsum tau ua raws li qhov tsim nyog conductivity kuaj kom paub tseeb tias tsis muaj kev puas tsuaj;
4. Xyuas seb cov hlua khi thiab cov hlua khi puas xoob.
