Core tips: the film-forming substances in the coating film mainly include powder, binder, etc., as well as solid components of additives The volume percentage of rigid pigment and filler particles in the whole coating film is the volume concentration of the paint The English name is: segment volume concentration, abbreviated as PVC PVC determines the cost of coating, and also involves the coating performance High PVC value, many rigid components in the film, brittle film, good stain resistance, good film permeability, low density; low PVC value, soft binder in the film Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: the film-forming substances in the coating film mainly include powder, binder, etc., as well as solid additives The volume percentage of rigid pigment and filler particles in the whole coating film is the volume concentration of the paint The English name is: segment volume concentration, or PVC for short PVC determines the cost of coating, and also involves the coating performance High PVC value, more rigid components in the film, brittle film, good stain resistance, good film permeability, low density; low PVC value, more soft binders in the film, good film sealing, poor stain resistance PVC calculation formula: PVC = 100 × [VP / (VP + VB)]; where: VP - volume of pigments and fillers, VB - volume of binder In the production process of coating, the weight is taken as the unit of calculation, but the performance of coating film is generally expressed by volume after drying, because the dry coating film is a multi-component structure composition, and the volume relationship between the various components plays an important role in the performance of coating film Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
