...в спирте 96% который хранился в ПЭТ от биолы есть белесая взвесь.Я не знаю что это но лучше в спирт горелке это сожгу
Причем хочу обратить внимание что цифра которая внутри треугольника .. отличается.
Специально просмотрел бутылки - фирменные из-под масла имеют также значек "пищевой"
НО! Бутылки в которых производитель продает щелочные или кислотные растворы на вид изготовлены из другого материала с маркировкой PE-HD и цифрой 2 в треугольнике
Хм... Не могло быть так, что спирт был налит не тщательно вымытую от остатков напитка "Биолу" (т.е. была ли эта баклажка из-под напитка с ароматизаторами и красителями или из-под минеральной воды)?
А цифры внутри треугольника, как выяснилось - это "Международные универсальные коды переработки":
- #1 PET(E) Полиэтилентерефталат
- #2 PEHD (HDPE) Полиэтилен высокой плотности (ПЭВП)
- #3 PVC Поливинилхлорид (ПВХ)
- #4 PELD (LDPE) Полиэтилен низкой плотности (ПЭНП)
- #5 PP Полипропилен
- #6 PS Полистирол
- #7 O(ther) Прочие пластмассы

High Density Polyethylene: HDPE is the most widely used resin for plastic bottles. This material is economical, impact resistant, and provides a good moisture barrier. HDPE is compatible with a wide range of products including acids and caustics but is not compatible with solvents. It is supplied in FDA approved food grade. HDPE is naturally translucent and flexible. The addition of color will make HDPE opaque although not glossy. HDPE lends itself readily to silk screen decoration. While HDPE provides good protection at below freezing temperatures, it cannot be used with products filled at over 160 °F (71.1 °C) or products requiring a hermetic (vacuum) seal.
Low Density Polyethylene: LDPE is similar to HDPE in composition. It is less rigid and generally less chemically resistant than HDPE, but is more translucent. LDPE is used primarily for squeeze applications. LDPE is significantly more expensive than HDPE.
Polyethylene Terephthalate: Polyethylene Terephthalate (PET, PETE or polyester) is commonly used for carbonated beverage and water bottles. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetones and ketones will attack PET) and a high degree of impact resistance and tensile strength. The orienting process serves to improve gas and moisture barrier properties and impact strength. This material does not provide resistance to high temperature applications—max. temp. 160 °F (71.1 °C).
Polyvinyl Chloride: PVC is naturally clear, has extremely good resistance to oils, and has very low oxygen transmission. It provides an excellent barrier to most gases and its drop impact resistance is also very good. This material is chemically resistant, but it is vulnerable to solvents. PVC is an excellent choice for salad oil, mineral oil, and vinegar. It is also commonly used for shampoos and cosmetic products. PVC exhibits poor resistance to high temperatures and will distort at 160 °F (71.1 °C), making it incompatible with hot filled products
Polypropylene: Polypropylene(PP) is used primarily for jars and closures and provides a rigid package with excellent moisture barrier. One major advantage of polypropylene is its stability at high temperatures, up to 200 °F. Polypropylene is autoclavable and offers the potential for steam sterilization. The compatibility of PP with high filling temperatures is responsible for its use with hot fill products such as pancake syrup. PP has excellent chemical resistance, but provides poor impact resistance in cold temperatures
Polystyrene (PS): Styrene offers excellent clarity and stiffness at an economical cost. It is commonly used with dry products including vitamins, petroleum jellies, and spices. Styrene does not provide good barrier properties, and exhibits poor impact resistance.
Fluorine Treated HDPE: Bottles are exposed to fluorine gas in a secondary operation, are similar in appearance to HDPE and have exceptional barrier properties to hydrocarbons and aromatic solvents. Fluorine treated bottles are excellent for use with insecticides, pesticides, herbicides, photographic chemicals, agricultural chemicals, household and industrial cleaners, electronic chemicals, medical cleaners and solvents, citrus products, d-limone, flavors, fragrances, essential oils, surfactants, polishes, additives, graffiti cleaning products, pre-emergents, stone and tile care products, waxes, paint thinner, gasoline, biodiesel, xylene, acetone, kerosene and more.
For non-bottle applications, fluorination of plastic can provide compliance with state and federal regulations. An example would be fluorination plastic fuel tanks used for lawn and garden equipment, automobiles, etc.
Post Consumer Resin (PCR): PCR is a blend of reclaimed natural HDPE (primarily from milk and water containers) and virgin resin. The recycled material is cleaned, ground and recompounded into uniform pellets along with prime virgin material especially designed to build up environmental stress crack resistance. PCR has no odor but exhibits a slight yellow tint in its natural state. This tint can be hidden by the addition of color. PCR is easily processed and inexpensive. However, it cannot come into direct contact with food or pharmaceutical products. PCR can be produced in a variety of recycled content percentages up to 100%.
K-Resin SBC: K-resin is ideally suited to a wide variety of packaging applications by virtue of its sparkling clarity, high gloss, and impact resistance. K-Resin, a styrene derivative, is easily processed on polyethylene equipment. It is suitable for packaging many products but is specifically incompatible with fats and unsaturated oils or solvents. This material is frequently used for display and point-of-purchase packaging.
P.S. Просто у меня неоднократно спирт хранился в самых разнообразных баклажках (из-под минералок и "крашеных" напитков, но никакого осадка ни разу не наблюдал...) Спирт хранился длительное время
P.P.S. А вообще то, может модераторам стоит переместить эти наши посты (по обсуждению столь актуальной темы) в отдельный топик? А то, вроде как, не самое подходящее место для подобной дискуссии в теме "Пеший маршрут Ангарский перевал-Солнечногорское"?

, оказывается,можно водку из ПЭТ пить.А я ему тогда на слово поверил
