Polyvinyl Alcohol (PVA) -Wanwei
Piav qhia
Saib xyuas
Cia siab Wanwei High-tech Materials Co., Ltd. mus txog "Wanwei" yog cov tsis ntawm peb nyob rau hauv tswj kev polyvinyl alcohol (PVA) series products thiab ua kev tshaj npawm thiab tshaj, npe yog vinyl acetate mus txog calcium carbide acetylene method thiab petroleum ethylene method los noj raws, npe yog ethylene mus txog biological alcohol los noj raws, methanol los noj raws, peroxide los noj raws, kawg yuav tsum polymerization, alcoholysis thiab ib qab kev.
Txhais Nploog
Cov tsis: Polyvinyl Alcohol (PVA)
Tawj hauv kawm: -[CH2CH(OH)]n
Cov tsis muaj rau hwm:
Rau txhua yog hauj siab, xym ntawm lub tshaj rau thiab lub tshaj npawd (rooj cas lwm qhov cas) thib yog rau txhua flocculent tshaj (rooj cas lwm qhov cas). Tsawg ntsiav: 1.19-1.31 g/cm 3, xym PVA tsis tsawg ntsiav: 0.42-0.52 g/cm 3, flocculent tsis tsawg ntsiav: 0.20-0.27 g/cm 3.
Tswv teem kawm nyob
- Tsis muaj nyob rau hais: Molecules PVA li muaj yuav tsum nyob rau hais los yog pom no yog cov duab hydroxyl. Nws muaj yooj ib tug hais tswv ntawv yug li cas hais, muaj yooj ua hais thiab cas hais, los yog cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais thiab cas hais.
- Cas tias: Lub tshaj muaj yooj tias cas, muaj yooj cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas thiab cas.
- Tsis mus rau ndawg: Txhais yog kawg tias tau ntawm lub npe tsis, npe tsis, los yog hwm thiab muaj yim thiav thiab, thiab muaj tsis npaug lwm thiab tsis muaj qhua.
- Stability thiaj txog: Lub txhais yog hais tias lawv, thiaj txog ua kev pib twb nyob rau hauv lub sis tsis hluas, tsis hlub, thiab tsis muaj qhua.
- PVA yog cov polymer qhov secondary hydroxyl groups. Lub secondary hydroxyl group nyob rau PVA molecular formula muaj hais tias hloov reactivity, thiab muaj ua kev tsis tuaj yeej sib nrhoos thiab low molecular alcohol, los yog esterification, etherification, acetalization, thiab muaj ua kev rau hauv ib tug inorganic compounds thiab organic compounds. Tsuas tsis muaj tox thiab animals, muaj ua kev natural degradation, thiab yog hais tias green products.
