1. Cov khoom siv tshuaj lom neeg thiab lub cev ntawm cov khoom siv
Random sampling thiab tshuaj xyuas yuav tsum tau ua raws li cov kev sim dav dav rau cov ntoo -raws li panels thiab surfaced wood-raws li panels.
Kev ntsuas qib yuav tsum tau ua nrog 45 yam ntawm cov kua qaub muaj zog thiab muaj zog alkaline tshuaj reagents, suav nrog sulfuric acid, acetic acid, nitric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, formaldehyde tov, sodium hypochlorite, hydrogen peroxide, ethyl acetate, magnesium oxide, ammonium potassium hydroxide, thiab lwm yam.
2. Lub cev ua tau zoo ntawm lub cev
Kev sim ua raws li tus qauv rau siab -siab zoo nkauj laminates impregnated nrog thermosetting resin ntawv, tag nrho cov khoom ntawm lub cev yuav tsum tau raws li tus qauv yuav tsum tau:
Kev tiv thaiv rau cov dej kub npau npau, qhuav kub tsis kam, tiv thaiv kab mob tiv thaiv sodium hydroxide thiab hydrogen peroxide, thiab luam yeeb kub hnyiab tau mus txog qib 5 uas tsis muaj qhov hloov pauv;
Crack resistance test (70 degree, 24 teev): Qib 5 tsis muaj qhov tawg;
Impact resistance (324g poob ntawm 1m qhov siab): Tsis muaj qhov tawg;
Qhov hnav tsis kam: Ntau dua lossis sib npaug rau 760 kiv puag ncig;
Tensile zog: 95.9 MPa;
Scratch kuj: Qib 1, tsis muaj qhov nruam ncig khawb hauv qab 1.5N load.
Ua raws li kev cai lij choj thoob ntiaj teb kev nyab xeeb hauv hiav txwv; Qhov siab tshaj plaws tag nrho cov nqi calorific ntawm cov khoom Tsawg dua los yog sib npaug rau 45MJ / m², nrog rau kev tsim nyog cov nplaim hluav taws xob kis tau zoo.
Kuaj ib tug universal vaj huam sib luag kev ua tau zoo xeem qauv; ntim kuj nce mus txog 9.8 × 10⁸ Ω, nrog zoo heev antistatic kev ua tau zoo.
Kev tshuaj xyuas thiab pom zoo los ntawm kev tso cai hlau tshuaj ntsuam xyuas cov koom haum raws li cov khoom siv tsheb ciav hlau thoob ntiaj teb kev tiv thaiv ib puag ncig thiab cov qauv kev nyab xeeb.
3. Kev tiv thaiv ib puag ncig
Cov ntsiab lus txhuas ua raws li thoob ntiaj teb cov khoom siv kev nyab xeeb kuaj cov qauv:
Lead cov ntsiab lus ntawm tus number case: 0.002%;
Cov ntsiab lus ntawm cov ntaub ntawv laminated: 0.002% (tus qauv txwv Tsawg dua lossis sib npaug rau 0.01% W / W).
Formaldehyde emission ntawm ntoo-raws li cov ntaub ntawv vaj huam sib luag raws li cov khoom siv kho kom zoo nkauj sab hauv tsev E1-theem ib puag ncig tiv thaiv tus qauv.
Volatile organic compound test indicators:
VOC concentration Tsawg dua lossis sib npaug ntawm 0.004mg / m³;
Formaldehyde concentration Tsawg dua lossis sib npaug ntawm 0.004ppm;
Tag nrho aldehyde concentration Tsawg dua lossis sib npaug ntawm 0.004ppm;
Phenylcyclohexene <0.001mg/m³;
Tsis pom cov monomer uas tsis yog{0}}methane hydrocarbons.
Txhua qhov ntsuas tau dhau los ntawm kev soj ntsuam ntawm cov chaw tso cai thoob ntiaj teb, nrog cov ntawv tshaj tawm kev xeem muaj.
Kuaj raws li kev ceev ceev thoob ntiaj teb thiab kev tiv thaiv ib puag ncig cov ntsiab lus: lub teeb nrawm Qib 4-5; formaldehyde emission Tsawg dua lossis sib npaug ntawm 0.005mg / m³; TVOC Tsawg dua lossis sib npaug li 0.09mg/m²·h. Tag nrho cov ntawv xeem tau lees paub los ntawm CMA thiab CNAS cov ntawv pov thawj lub cev.
4. Antibacterial Performance
Kev ntsuam xyuas los ntawm SGS raws li ISO 22196: 2011 thoob ntiaj teb tshuaj tua kab mob tus qauv, cov khoom xa tawm cov nyhuv antibacterial zoo:
Antibacterial kev ua ub no tus nqi tiv thaiv Escherichia coli: 6.6
Antibacterial kev ua ub no tus nqi tiv thaiv Staphylococcus aureus: 6.2
5. Tom qab-Kev Pabcuam Muag Khoom Muag
Thawj tom qab- tsab ntawv cog lus rau kev muag khoom thiab ua tiav cov ntaub ntawv xeem raug cai yuav tsum tau muab los lav qhov zoo ntawm cov ntaub ntawv tseem ceeb rau kev siv mus ntev -.
