1. Txheeb xyuas cov khoom siv: Ua ntej lub ntuj tsim lossis cov khoom siv rov ua dua tshiab.
Cov ntaub ntawv pom zoo: Cov ntaub ntawv ntuj xws li kraft ntawv, ntawv ntshiab, thiab tsis yog - woven fabric yog ib puag ncig tus phooj ywg thiab biodegradable.
Kev xaiv thib ob: PET (polyester zaj duab xis) muaj cov tshuaj lom neeg ruaj khov, tuaj yeem rov ua dua tshiab, thiab tsim nyog rau chav ua noj thiab cov khoom siv hluav taws xob.
Xaiv nrog ceev faj: Cov khoom siv PVC zoo ib yam yuav muaj cov yas chloride thiab hnyav hlau stabilizers thaum lub sij hawm tsim khoom, yog qhov nyuaj rau degrade, thiab yooj yim tso tawm cov pa phem thaum kub kub.
Nyiam hloov kho ib puag ncig tus phooj ywg PVC: Qee lub npe tau txais halogen-dawb thiab qis-VOC cov qauv; xyuas cov khoom qhia.
✅ Tswv yim: Ntim cov ntawv sau tias "biodegradable," "halogen{0}}dawb," thiab "qis-VOC" yog kev ntseeg siab dua.
2. Tsis hnov tsw: Tsis muaj pungent tshuaj tsw qab yog ib qho yooj yim yuav tsum tau. Tom qab qhib lub ntim ntawv, siab - cov ntawv nplaum zoo ib puag ncig yuav luag tsis muaj ntxhiab tsw lossis tsuas yog kua nplaum me ntsis.
Yog tias muaj cov ntxhiab tsw tsw phem (xws li cov yas hlawv lossis xim tsis hnov tsw), nws yuav muaj cov kuab tshuaj benzene, formaldehyde, los yog ink inferior; txiav kev siv tam sim ntawd. Kev Ceeb Toom Tshwj Xeeb: Cov menyuam yaus cov ntawv nplaum thiab cov tattoo ib ntus tuaj rau hauv cov tawv nqaij ncaj qha; tej yam tsw txawv txawv warrants ceev faj.
3. Tshawb xyuas Cov Ntawv Pov Thawj: Nrhiav Cov Ntawv Tso Cai Rau Ib puag ncig. Cov ntawv nplaum uas tau dhau qhov kev xeem thib peb - yog qhov muaj kev ntseeg siab dua. Ua tib zoo saib xyuas cov ntawv pov thawj hauv qab no:
Tuam Tshoj Environmental Labeling (Tuam Tshoj Kaum-Nplhaib Certification): Lub teb chaws - theem ib puag ncig tus qauv npog txwv formaldehyde, hnyav hlau, VOCs, thiab lwm yam.
SGS Environmental Certification: Kev ntsuam xyuas rau polycyclic aromatic hydrocarbons (PAHs), phthalates, lead, cadmium, thiab lwm yam teeb meem tshuaj; cov ntaub ntawv qhia tau tseeb.
EN 71-3 (EU Toy Standard): nruj me ntsis txwv cov ntsiab lus ntawm migratable cov khoom, muaj feem xyuam rau cov me nyuam cov khoom.
GREENGUARD (Tebchaws Asmeskas): Cov kev xav tau siab heev rau VOC emissions, haum rau ib puag ncig rhiab heev.
🔍 Thaum yuav khoom, thov tus neeg muag khoom muab cov ntaub ntawv xeem, tsom rau formaldehyde emissions (tsawg dua lossis sib npaug li 0.05mg / m³) thiab PAH cov ntsiab lus.
4. Kev txheeb xyuas tus cwj mem thiab kua nplaum: Kev nyab xeeb yog qhov tseem ceeb hauv kev sib cuag ncaj qha
Ink: Xaiv cov dej-raws li lossis ib puag ncig tus phooj ywg inks, zam cov xim uas muaj cov hlau hnyav xws li txhuas, cadmium, thiab naphthalene, tshwj xeeb tshaj yog rau daim tawv nqaij -hu rau cov ntawv nplaum (xws li tattoos ib ntus).
Glue: Ua ntej formaldehyde-dawb, siab-sensitive, lossis tshem tau cov nplaum, zam cov kuab tshuaj organic-raws li cov kua nplaum los txo cov formaldehyde thiab VOC emissions.
5. Kev sim hauv tsev yooj yim
Water Immersion Test: Muab daim nplaum rau 12 teev. Ib puag ncig tus phooj ywg cov ntawv nplaum uas tsis ploj, delaminate, lossis tev qhia cov xim ruaj khov thiab cov nplaum nplaum.
Hlawv Test: Ignite ib daim me me. Cov ntaub ntawv ntuj tsim ib qho me me, greyish - nplaim dawb uas tsis muaj pa taws dub; PVC kub hnyiab nrog cov pa luam yeeb dub thiab tsw ntxhiab tsw, ua rau muaj kev pheej hmoo siab.
Kev kuaj tawv nqaij: Siv rau sab hauv ntawm lub dab teg rau 2 teev. Tsis muaj qhov liab los yog khaus qhia tias nws haum rau cov menyuam yaus lossis cov neeg uas muaj tawv nqaij rhiab heev. ⚠️ Kev ceeb toom tshwj xeeb: Thaum xaiv cov ntawv nplaum lossis cov tattoo ib ntus rau cov menyuam yaus, nco ntsoov xaiv cov npe nrov thiab zam "peb-tsis" cov khoom (cov khoom lag luam tsis muaj npe, chaw nyob, lossis hnub tsim khoom) los tiv thaiv kev nqus ntawm cov carcinogens xws li polycyclic aromatic hydrocarbons los ntawm daim tawv nqaij.
