Kev tsim cov hnab yog qhov zoo vim tias nws tsis tas yuav siv cov khoom kim txawv teb - qhov tsim nyog ntawm kev tsim khoom hauv tsev yuav tsis raug nqi ntau. Thiab tseem coj mus rau hauv tus account qhov tseeb tias koj feem ntau yuav tsum tau xaj cov khoom nyoos rau kev tsim cov khoom lag luam polyethylene txawv teb chaws, peb tuaj yeem hais tias nws nyuaj rau nrhiav cov khoom pheej yig hom kev lag luam niaj hnub no.
Nws yog qhov tsim nyog
- - kev tso cai los ntawm thawj tswj hwm hauv cheeb tsam, tshuaj ntsuam hluav taws, Rospotrebnadzor thiab kev pabcuam ib puag ncig;
- - txheej txheej khoom (extrusion thiab flexographic);
- - thaj chaw hauv cheeb tsam kev lag luam hauv nroog txij li 100 square metres hauv cheeb tsam;
- - sib cog lus rau kev muab cov khoom raw rau polyethylene ntau lawm.
Cov Lus Qhia

Tau txais cov ntawv tso cai rau kev teeb tsa polyethylene ntau lawm - koom tes nrog txoj haujlwm nrog lub tuam tsev kev tsim kho vaj tsev thiab kev npaj hauv nroog ntawm cov thawj coj hauv zos, tau txais kev tso cai los ntawm Rospotrebnadzor, tshuaj xyuas hluav taws thiab kev pabcuam ib puag ncig. Qhov kev tso cai ua ntej ntawm txhua tus neeg tswj hwm muab rau "lub teeb ntsuab" tsuas yog thaum pib ua haujlwm ntawm cov khoom siv ntau lawm - kev kuaj xyuas ntau dhau los lawm yav tom ntej. Koj yuav tsum ua tib zoo saib xyuas qhov teeb meem ntawm kev rov ua dua tshiab pov tseg - yog tias koj tsis tuaj yeem ua tiav ntawm txoj haujlwm no, koj tuaj yeem tau txais "tsis tsim nyog" los ntawm ntau cov kev pabcuam kev tshuaj xyuas ib zaug.

Tshawb xyuas kev ua lag luam rau cov khoom siv extrusion koj xav tau thiab ntsuas ntau yam kev xav. Cov khoom siv hauv tsev tshiab tuaj yeem sib npaug nrog cov khoom siv txawv teb chaws - ob qho tib si ntawm kev ua haujlwm thiab ntawm tus nqi. Qhov twg nres yog nyob ntawm koj, txoj kev xaiv nrog cov khoom siv txawv teb tshiab txawv ntawm tus nqi los ntawm thawj ob zaug ob peb zaug, thiab tsis yog txhua tus neeg tuaj yeem them taus qhov khoom kim heev no thaum pib.

Nrhiav qhov chaw kom deb ntawm thaj chaw nyob hauv nroog, tab sis tsis muaj teeb meem nrog txoj kev nkag mus (suav nrog rau cov tsheb thauj khoom). Lub koom haum ntawm polyethylene ntau lawm yuav tsum muaj thaj chaw loj - kev xaiv los ntawm 100 square metres thiab 8 metres hauv qhov siab yuav tau txiav txim siab. Nws tseem yog qhov yuav tsum tau muab thaj chaw rau lub tsev rau khoom - cov khoom tiav, thiab tshwj xeeb tshaj yog cov ntaub ntawv raw khoom, yuav siv ntau qhov chaw.

Kos npe rau daim ntawv cog lus rau kev muab cov khoom lag luam polyethylene ntawm ntau hom - nws yuav yog qhov khoom lag luam tseem ceeb rau kev tsim cov hnab. Ntau lub tsev lag luam polyethylene yuav cov khoom siv sab nraum zoov dhau ntawm USSR thiab tau tsim kev sib raug zoo mus ntev nrog cov neeg muab khoom txawv teb chaws. Nws yog qhov tau hais tias tam sim no muaj twb tau qee qhov kev pom zoo los ntawm cov neeg xa khoom polyethylene hauv Lavxias thiab Ukraine uas tau txais txiaj ntsig hauv txhua txoj haujlwm, tab sis nyob rau hauv rooj plaub no koj yuav tau ua rau qee lub sijhawm los ntawm kev sim thiab kev ua yuam kev kom txog thaum muaj kev xaiv tau pom.
