PVC foamed ntawv muaj cov cwj pwm ntawm siab ntom, tawv zoo nkauj, ntsis dej cov ntsiab lus, ua tau yooj yim, zoo nkauj, tsis tshua pob caus, ci xim thiab zoo li ntawd. Nws yog ib qho khoom siv rau cov khoom siv hauv chav dej. Daim ntoo roj hmab nrog cov khoom siv zoo tuaj yeem khaws cia rau hauv dej rau peb lub hlis thiab yuav khaws cia tsis muaj deformation thiab non-corrosion, uas yog unmatched los ntawm pawg neeg sab nrauv.
Ces saib lwm yam khoom siv hlau li cas, feem ntau 304 xim hlau tsis zoo, lub da dej daim iav yuav tsum tsis muaj dej, tsis muaj pa thiab pov thawj. Kev kho kom zoo hauv chav da dej; cov tsev yooj yim sab nraum zoov, tus saib xyuas cov ntawv; kho kom zoo nkauj vaj tse, kho kom zoo nkauj; txoj kev kos npe rau daim ntawv sau npe thiab lwm cov hauj lwm. Lub ntsiab ntawm kev noj qab haus huv ntawm formaldehyde yog raws li nram no:
PVC ua npuas Board, ib tug, stimulating nyhuv: qhov teeb meem loj ntawm formaldehyde yog cov stimulation ntawm daim tawv nqaij mucous membrane. Formaldehyde yog ib yam tshuaj lom tiv thaiv, uas yuav khi tau cov protein, thiab thaum lub siab concentration yog nqus pa, mob ntsws loj thiab txoj hlab ntsha, qhov muag khaus, mob taub hau. b, sensitization: kev hu ncaj nraim nrog cov formaldehyde tuaj yeem ua rau tsis haum rau dermatitis, pigmentation, necrosis, bronchial asthma thaum nqus tau cov roj ntsha hauv formaldehyde.
PVC foamed ntawv, c, mutagenic nyhuv: siab concentration of formaldehyde kuj yog ib yam khoom uas yog genotoxic. Cov tsiaj txhu yuav ua rau nasopharyngeal hlav thaum nqus tau ntawm cov ntshav siab nyob hauv kev sim. d, zoo siab ua haujlwm: mob taub hau, kiv taub hau, qaug zog, xeev siab, ntuav, mob hauv siab, qhov muag mob, mob caj pas, mob plab anorexia, palpitations, insomnia, yuag poob, nco ploj thiab otonomogia mob; Ntev ntev ntev rau cov poj niam cev xeeb tub yuav ua rau tus me nyuam hauv plab, Ua rau lawv tuag taus, ua rau cov txiv neej muaj peev xwm ua rau cov txiv neej phev deformity, tuag thiab lwm yam.
