Taw qhia:
Plastics yog dav siv nyob rau hauv ntau yam lag luam vim lawv versatility thiab nqi-zoo.Txawm li cas los xij, lawv cov flammability ua rau muaj kev phom sij, ua rau cov nplaim hluav taws kub hnyiab yog qhov tseem ceeb ntawm kev tshawb fawb.Qhov kev sim no tsom mus tshawb xyuas qhov ua tau zoo ntawm cov nplaim hluav taws sib txawv hauv kev txhim kho hluav taws kub ntawm cov yas.
Txoj kev:
Hauv txoj kev tshawb no, peb xaiv peb hom yas uas siv ntau: polyethylene (PE), polypropylene (PP), thiab polyvinyl chloride (PVC).Txhua hom yas tau kho nrog peb cov nplaim hluav taws sib txawv, thiab lawv cov khoom tiv thaiv hluav taws tau muab piv nrog cov qauv tsis kho.Cov nplaim retardants suav nrog ammonium polyphosphate (APP), aluminium hydroxide (ATH), thiab melamine cyanurate (MC).
Cov txheej txheem sim:
1. Kev Npaj Qauv: Cov qauv ntawm txhua hom yas tau npaj raws li tus qauv qhov ntev.
2. Kev kho nplaim hluav taws kub: Cov nplaim hluav taws uas xaiv tau (APP, ATH, thiab MC) tau sib xyaw nrog txhua hom yas raws li qhov pom zoo.
3. Kev Ntsuas Hluav Taws Xob: Cov qauv yas kho thiab tsis kho tau raug tswj kom muaj hluav taws kub hnyiab siv lub tshuab hluav taws xob Bunsen.Lub sij hawm ignition, nplaim taws, thiab cov pa luam yeeb tsim tau raug soj ntsuam thiab kaw.
4. Kev Sau Cov Ntaub Ntawv: Kev ntsuas suav nrog lub sijhawm rau qhov hluav taws kub, nplaim hluav taws kub hnyiab, thiab kev ntsuam xyuas pom ntawm cov pa luam yeeb.
Cov txiaj ntsig:
Cov txiaj ntsig ua ntej qhia tau hais tias tag nrho peb cov nplaim hluav taws kub hnyiab tau txhim kho qhov hluav taws kub ntawm cov yas.Cov qauv kho tau nthuav tawm lub sijhawm hluav taws xob ntev dua thiab cov nplaim taws qeeb dua piv rau cov qauv tsis kho.Ntawm cov retardants, APP tau pom qhov ua tau zoo tshaj plaws rau PE thiab PVC, thaum ATH pom tau zoo heev rau PP.Cov pa luam yeeb tsawg kawg nkaus tau pom nyob rau hauv cov qauv kho thoob plaws txhua yam yas.
Kev sib tham:
Cov kev pom zoo txhim kho hauv kev tiv thaiv hluav taws qhia txog qhov muaj peev xwm ntawm cov nplaim hluav taws no los txhim kho kev nyab xeeb ntawm cov ntaub ntawv yas.Qhov sib txawv ntawm kev ua tau zoo ntawm cov yas hom thiab cov nplaim hluav taws xob tuaj yeem raug ntaus nqi los ntawm kev hloov pauv hauv cov tshuaj muaj pes tsawg leeg thiab cov khoom siv.Kev tshuaj xyuas ntxiv yog xav tau kom nkag siab txog cov txheej txheem hauv qab lub luag haujlwm rau cov txiaj ntsig tau pom.
Xaus:
Qhov kev sim no qhia txog qhov tseem ceeb ntawm cov nplaim hluav taws kub nyhiab hauv cov yas thiab qhia txog cov txiaj ntsig zoo ntawm ammonium polyphosphate, aluminium hydroxide, thiab melamine cyanurate ua cov nplaim hluav taws zoo.Cov kev tshawb pom no pab txhawb rau kev txhim kho cov ntaub ntawv yas zoo dua rau kev siv ntau yam, los ntawm kev tsim kho mus rau cov khoom siv.
Kev tshawb fawb ntxiv:
Kev tshawb fawb yav tom ntej tuaj yeem nkag mus rau hauv kev ua kom zoo ntawm cov nplaim hluav taws xob sib piv, kev ruaj ntseg ntev ntawm cov yas kho, thiab kev cuam tshuam ib puag ncig ntawm cov nplaim hluav taws.
Los ntawm kev ua qhov kev tshawb fawb no, peb lub hom phiaj los muab kev nkag siab zoo rau kev nce qib ntawm cov nplaim hluav taws kub nyhiab, txhawb cov ntaub ntawv muaj kev nyab xeeb thiab txo cov kev pheej hmoo cuam tshuam nrog cov yas tawg.
