polyvinyl alcohol (pva) -wanwei
description
overview
anhui wanwei summus tech materiae co., ltd. "wanwei" notam polyvinyli alcohole (pva) seriei productorum utendo technologiam et technologiam provectam, unum est acetas vinyl ex calcii carbide acetylenae methodo producta et petrolei methodo ethylene ut materia rudis, altera ethylene producta ab alcohole biologico ut materia rudis, methanolum ut solvendo, peroxide ut initiator, per polymerizationem, alcoholysim et alios processus.
Product Details
eget nomen: polyvinyl alcohol (pva)
formula hypothetica: -[ch2ch(oh)]n
corporis proprietates;
species est lanula alba, solida granula vel pulverulenta (processus alcoholysis alcali humilis) vel solidus flocculentus albus (processus alcoholysis altae alcali). gravitatis specificae: 1.19-1.31 g/cm3, lanula pva gravitatis specificae implens: 0.42-0.52 g/cm3, flocculenta gravitatis specificae implens: 0.20-0.27 g/cm3.
proprietatibus chemicis:
- aqua solutum: pva moleculae facile sunt in aqua solubiles, quia magnum numerum hydroxyli continent. Solubilitas eius cum augmento temperaturae aquae augetur, solum in aqua frigida dilatatur (accepta alcoholysis humilis in aqua temperata normali lente dissolvi potest), et in aqua calida perfecte dissolvi potest. eius solutio aquea bonas proprietates cinematographicas et cohaerentias habet.
- scelerisque stabilitas: productum mollit cum calefactum, signanter non mutat infra 40℃, 160℃ diu calefactio paulatim coloratur, dissolutio fit supra 220℃, ex aqua, acido acetico, acetaldehyde et butenali.
- resistentia chemica: productum vix acido infirmo, basi debili vel organico solvendo afficitur, et oleum excelsum habet resistentiam.
- stabilitatem repono: bonum productum stabilitatis, diu terminus repono in statu naturali sicco non fingit, non corrumpit, non absorbet humorem.
- pva est polymerus cum hydroxylo secundario. secundaria coetus hydroxyli in pva formulae hypothetica altam reactivity habet, et chemicae reactiones typicas efficere potest similes alcoholicis humilibus hypotheticis, sicut esterificatio, eterificatio, acetalization, etc., ac etiam cum multis compositis inorganicis et organicis compositionibus agere. hominibus et animalibus non noxia, naturaliter turpia, quae fructus virides cognoscuntur.
