Polyvinyl Sin (PVA) -Wanwei
Descriptio
Conspectus
Anhui Wanwei High-tech Materials Co., Ltd. producit series productorum "Wanwei" marcae polyvinyl alcoholis (PVA) per usum technologiae et artis praecipuae, unum ex acetato vinylis producto ex carbide calcis acetyleno et ethylene petroleo methodo ut materia prima, alterum ex ethylene producto ex biologico spiritu ut materia prima, methanol ut solvente, peroxide ut initiatore, per processus polymerizationis, alcoholysis et ceteros.
Producti Details
Nomen chimicum: Polyvinyl Alcohol (PVA)
Formula moleculare: -[CH2CH(OH)]n
Proprietates physicae:
Aspectus est albus lamina, granulosus vel pulverulentus solidus (processus low alkali alcoholysis) aut albus floccosus solidus (processus high alkali alcoholysis). Gravitas specifica: 1.19-1.31 g/cm 3, gravitas specifica laminae PVA: 0.42-0.52 g/cm 3, gravitas specifica flocculi: 0.20-0.27 g/cm 3.
Proprietates chimicae:
- Solubilis in aqua: Moleculae PVA facile solvuntur in aqua quia multas hydroxyl gruppos continent. Solubilitas eius aucta fit cum temperatura aquae crescit, tantum expanditur in aqua frigida (producta low alcoholysis lentissime dissolvuntur in aqua temperatura), et potest penitus dissolvi in aqua calida. Solutio eius in aqua bonam filmationem et cohaesionem habet.
- Stabilitas thermalis: Productum mollit quando calefit, non mutatur significanter infra 40℃, colorabitur paulatim si diu calefit ad 160℃, decompositio incipit super 220℃, producens aquam, aceticam acidum, acetaldehyde et butenal.
- Resistentia ad chimica: Productum vix affectatur ab acido vel base levi aut solvente organico, et altam resistenciam olei habet.
- Stabilitas in conservatione: Bonam stabilitatem producti habens, longa conservatio in statu arido naturali non putrescit, non deteriores, non humectat.
- PVA est polymerum cum hydroxylis secundariis. Hydroxyl secundarius in formula moleculae PVA habet altam activitatem et potest effectuare typicas reactiones chemicas similes ad alcoolum minus molare, sicut esterificatio, etherificatio, acetificatio, etc., et etiam reagere cum multis compositis inorganicis et organicis. Non venenum hominibus et animalibus, naturaliter degradabile, notum ut productum viride.
