Nyob rau hauv xyoo tas los no, nrog txoj kev loj hlob sai ntawm kev lag luam e-lag luam, ntau thiab ntau cov ntawv sau tuaj txawv teb chaws tshwm sim hauv peb lub laub yuav khoom. Yuav muaj qhov sib txawv ntawm cov qauv lossis cov kev qhia tshwj xeeb rau cov ntawv sau txog qhov zoo, kev nyab xeeb, kev noj qab haus huv, kev tiv thaiv ib puag ncig, kos npe, thiab lwm yam ntawm cov teb chaws, uas yuav ua rau qee cov khoom ua tau raws li cov kev cai ntawm cov qauv tsim lossis cov kev qhia tshwj xeeb ntawm lub tebchaws. keeb kwm, tab sis tej zaum yuav tsis tau raws li cov qauv ntawm Tuam Tshoj.
Niaj hnub no, peb yuav sib piv qee qhov sib txawv ntawm Suav thiab txawv teb chaws cov qauv sau ntawv los ntawm kev xav ntawm cov ntawv sau zoo thiab kev pheej hmoo ntawm kev nyab xeeb.
Phthalate plasticizer hauv roj hmab
Ntawm cov ntawv sau tuaj txawv teb chaws, Japanese ntawv sau tau ntes lub siab ntawm ntau tus neeg sau ntawv los ntawm kev tsim txiaj ntawm nws qhov zoo nkauj zoo nkauj. Nws humanized tsim thiab nruam innovation muab cov neeg siv khoom zoo dua.
Ua ntej, cia peb sib piv qhov sib txawv ntawm tus qauv Japanese ntawv sau JIS S 6050: 2002 Yas Eraser thiab cov qauv kev lag luam QB/T 2309-2020 Eraser siv xyoo no hauv Suav teb. Tus txheej txheem Japanese tsis muaj kev txwv rau phthalates.
Txhawm rau ua kom cov khoom muag muag ntau dua, cov roj hmab yas yuav ntxiv cov yas yas hauv cov khoom, thiab phthalate yog cov khoom siv plasticizer feem ntau hauv cov khoom yas. Phthalates muaj mutagenic, carcinogenic, kev ua me nyuam toxicity thiab lwm yam kev phom sij. Ntev ntev raug cov tub ntxhais hluas thiab cov menyuam yaus tuaj yeem ua rau muaj kab mob endocrine thiab ua rau lub cev xeeb tub. Nyob rau hauv xyoo tas los no, nws tau pom tias phthalates tau ntxiv rau qee cov roj hmab ua cov yas yas. Tom qab kev hloov kho ntawm Eraser (QB/T 2309-2020), qhov kev txwv ntawm rau qhov teeb meem phthalates xws li di (2-} ethyl) hexyl phthalate tau ntxiv, tab sis tus qauv Japanese tsis tau hloov kho.
Ua zoo ceeb toom:
Thaum yuav cov roj hmab, xyuam xim rau cov khoom lag luam daim ntawv lo, muab qhov tseem ceeb rau cov roj hmab cim nrog "kev tiv thaiv ib puag ncig", "tsis muaj plasticizer" thiab lwm cov lus qhia, thiab ceev faj nrog cov roj hmab nrog cov duab ntxim hlub thiab cov tshuaj tsw qab raws li qhov muag.
Cov organic teeb meem hauv cov kua nplaum
Kev siv cov ntaub ntawv tshiab thiab thev naus laus zis tsis yog tsuas yog ua rau cov khoom siv sau ntawv hauv kev ua lag luam zoo nkauj dua thiab ua kom zoo dua qub, tab sis kuj coj qee qhov kev pheej hmoo zoo tshiab. Piv txwv li, kua nplaum, los ntawm cov kua nplaum ua kua thiab cov kua nplaum ua kua nplaum rau cov kua nplaum nplaum, cov kua nplaum nplaum, cov kua nplaum hloov xim thiab cov kua nplaum kom qhuav sai hauv kev ua lag luam niaj hnub no, muaj ntau yam khoom thiab cov duab, thiab ntau hom khoom sib txawv.
Piv nrog rau cov qauv ntawm cov ntawv sau cov kua nplaum, Nyiv JIS S 6023: 1992 Cov kua nplaum thiab cov qauv kev lag luam hauv Suav teb QB / T 1961-2011 Cov kua nplaum ua haujlwm tsuas muaj ib qho kev txwv rau cov khoom tsis zoo: dawb formaldehyde, benzene, toluene ntxiv rau xylene, tag nrho cov volatile tshuaj thiab acrylamide, GB 21027 2020 ntxiv cov kev txwv ntawm acrylamide hauv kua gel.
Formaldehyde, benzene thiab acrylamide nyob rau hauv cov kua nplaum yuav muaj nyob rau hauv daim ntawv ntawm adhesives, preservatives, solvents thiab residual monomers, tab sis cov tshuaj no yog volatile toxic tshuaj, uas yuav ua rau muaj kev phom sij rau tib neeg lub cev thaum nqus tau ntau tshaj ib qho concentration.
Ua zoo ceeb toom:
Tam sim no, PVA / PVAL (polyvinyl cawv lossis nws qhov hloov pauv), PVP (polyvinylpyrrolidone) thiab lwm yam dej-raws li cov nplaum nplaum feem ntau yog siv rau hauv cov ntawv sau cov kua nplaum ntawm lub khw. Thaum xaiv cov kua nplaum, cov neeg siv khoom yuav tsum tau them sai sai rau seb cov khoom xyaw tseem ceeb ntawm cov kua nplaum yog cim rau ntawm daim ntawv lo, thiab sim xaiv cov kua nplaum nrog cov khoom siv hauv ib puag ncig.
