TiO2 efficiency in coatings : products and techniques for opacity optimisation / Paul Dietz in SURFACE COATINGS INTERNATIONAL, Vol. 100.1 (02-03/2017)  

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 100.1 (02-03/2017) . - p. 35-40 Titre : TiO2 efficiency in coatings : products and techniques for opacity optimisation Type de document : texte imprimé Auteurs : Paul Dietz, Auteur Année de publication : 2017 Article en page(s) : p. 35-40 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dioxyde de titane Opacité (optique) Pigments inorganiques Revêtements:Peinture Index. décimale : 667.2 Colorants et pigments Résumé : For those who have been in the coatings industry long enough, the rollercoaster ride of TiO2 price comes as no surprise. That said, the days of an even 10-year cycle in price have changed to shorter periods of high price (often painfully high) followed by longer periods of relatively low price (painful for the suppliers). Even when relatively "cheap", TiO2 continues to be one of the most expensive raw materials in a coating, so ensuring that the pigments is used correctly and efficiently remains a crucial business objective.

The Constitution of the Republic of South Africa provides for the sustainable management of the environment and pollution through the application of Section 24 in the Bill of Rights - the right to an environment that is protected. The right provides for a protected environment, reinforced by the right to information, locus standi and the opportunity to apply international law in the interpretation and enforcement process.

Understanding paint recycling and the barriers to it in SURFACE COATINGS INTERNATIONAL, Vol. 100.1 (02-03/2017)  

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 100.1 (02-03/2017) . - p. 50-52 Titre : Understanding paint recycling and the barriers to it Type de document : texte imprimé Année de publication : 2017 Article en page(s) : p. 50-52 Langues : Anglais (eng) Catégories : Déchets -- Elimination Peinture -- Recyclage Revêtements -- Aspect de l'environnement:Peinture -- Aspect de l'environnement Royaume-Uni Index. décimale : 667.9 Revêtements et enduits Résumé : In 2015, the BCF commissioned a leftover paint survey, distributed to a nationally representative sample of adults and established that on average, each household in the UK has six cans of unused paint in their sheds or garages. What may seem like a minor inconvenience in household storage amounts to a serious environmental challenge, with a total of 55 million litre or 71500 tonnes of paint leftover each year which when disposed, 98% ends, up in landfill or is incinerated. Note de contenu : - Question 1. Does your HWRC accept liquid paint ? - Question 2.1. How do you store paint at your HWRC ? - Question 2.2. Do you pre-sort paint to separate SB paint from WB paint ? - Question 2.3. What is th edestination of the SB paint, once sorted ? - Question 2.4. What is the destination of the WB paint, once sorted ? - Question 2.5. If you send to a paint recycler, why do you use this route ? - Question 2.6 Provide an average cost/tonne to send for paint disposal - Question 3.1. What advice do you give to the public if they ask about paint disposal - Question 3.2. Why does your HWRC not accept liquid paint ? - Question 3.3. What would have to change for your HWRCs to accept liquid paint ?
