УПРОЧНЕННЫЕ ВОЛОКНА ПОЛИМОЛОЧНОЙ КИСЛОТЫ

Изобретение относится к химической технологии полимерных волокон и касается упрочненных волокон полимолочной кислоты. Волокна из полимолочной кислоты получают из термопластической композиции, которая содержит полимолочную кислоту и полимерную упрочняющую добавку. Упрочняющая добавка может быть диспергирована в непрерывной фазе полимолочной кислоты в виде дискретных физических доменов. Эти домены имеют определенный размер, форму и распределение и при вытяжении волокон они поглощают энергию и принимают удлиненную форму. Это способствует получению композиции более пластичной и мягкой по сравнению с жесткой полимолочной кислотой, не содержащей таких доменов. Изобретение обеспечивает создание волокон из полимолочной кислоты, обладающих хорошими механическими свойствами - хорошими параметрами удлинения и высокой прочностью. 5 н. и 15 з.п. ф-лы, 8 ил., 8 табл., 18 пр.

ЦЕЛЛЮЛОЗНЫЕ НАНОФИЛАМЕНТЫ С ВЫСОКИМ КОЭФФИЦИЕНТОМ ВЫТЯЖКИ И СПОСОБЫ ИХ ПОЛУЧЕНИЯ

Раскрыт новый способ получения в промышленном масштабе целлюлозных нанофиламентов (ЦНФ, CNF) с высоким коэффициентом вытяжки из натуральных лигноцеллюлозных волокон. Способ состоит из многопроходного рафинирования при высокой консистенции (РВК, HCR) химических или механических волокон с использованием специфических комбинаций интенсивности рафинирования и энергии, затраченной на рафинирование единицы массы целлюлозы. ЦНФ, полученные с помощью настоящего изобретения, представляют собой смесь тонких филаментов с шириной в субмикронах и длиной от десятков микрометров до нескольких миллиметров. Полученный продукт образует совокупность свободных филаментов и филаментов, связанных с сердцевиной волокна, из которого они произведены. Пропорция свободных и связанных филаментов регулируется, по большей части, суммарной удельной энергией, приложенной к целлюлозной массе в рафинере. Такие ЦНФ отличаются от других целлюлозных материалов с фибриллярной структурой их высоким коэффициентом вытяжки и сохраненной ...

Between the base metal (e.g. tungsten) and the emissive layer an intermediate layer is provided consisting of a silicide of the base metal, to prevent the formation of undesirable reaction products and interface compounds between the base and emissive materials. In an example a tungsten coil is heated with powdered silicon in a stream of equal parts of hydrogen and hydrochloric acid gas at 700‹- 950‹-1400‹ C., to form the tungsten silicide or disilicide. Additionally metal grains which have been similarly coated with silicide are mixed with the emissive material. The cathodes are particularly useful in fluorescent mercury discharge lamps, where they reduce blackening.

Thermoset resin fibres used in composite materials

The invention relates to composite materials comprising curable thermoset resin fibre components (10) and reinforcing fibres (14). The thermoset resin fibre components (10) may comprise a single fibre or a plurality of fibres commingled together. The properties and characteristics of the thermoset resin are chosen according to the materials to be produced therefrom. The thermoset fibre components (10) may be woven into reinforcement fibres (14) to form prepregs. Non-reinforcing thermoplastic fibres may be commingled and co-woven with the thermoset fibre components, as may a curing agent fibre.

Fibre reinforced concrete

Fibre reinforced concrete comprises thin steel wire of diameter between 0.05 and 0.3 mm in quantities up to 2.5% density. At least 30% of the fibres have an l/d ratio of 150 or more. To avoid the problem of balling when mixing, two alternatives are suggested. The first consists of strands of fibre, cut from recycled vehicle tyres. The second consists of a mixture of fibre lengths and thicknesses, giving a wide distribution of l/d ratios, which has the effect of reducing balling tendancy so that densities up to 1.5% can be achieved.

[Also in Division D1] Tobacco smoke filters are formed from a filamentary material to produce a continuous mass of interconnected crimped filamentary-like ribbons of the type described in Specification 1,145,976, the ribbons being formed from a molecularly oriented film composed of 40-70% of polyolefin and of 30-60% of polystyrene. Polypropylene and polyethylene are the preferred polyolefins. Interconnection is effected by spraying the filamentary mass with a plasticizer for polystyrene such as diethyl, dibutyl and di-(2-ethylhexyl) phthalates.

Manufacture of silicon carbide fibres

Submicroscopic b -SiC fibres are made by mixing SiO2 and C in a molar ratio of 1:1 to 10 in a reaction chamber, reacting the mixture at 1375 DEG to 1575 DEG C. in the presence of a COcontaining atmosphere, the CO having a partial pressure of 5 to 500 mm. Hg, forming the fibres from the reaction product at 1050 DEG to 1380 DEG C. and cooling the fibres to room temp. The atmosphere may also contain at least one of H2, He, N, and Ar and have a sum of partial pressures of 760 mm. Hg. The time to form the fibres may be 2 to 24 hrs. The reaction chamber may be evacuated to an abs. pressure of not more than 5 mm. Hg and heated to 600 DEG C. after providing the SiO2 and C mixture so as to allow complete degassing. The fibres may be cooled by cooling the chamber to 600 DEG C., introducing air and cooling further to room temp. The fibres have an average diameter of 250 <\>rA, a length up to 100m , a length to diameter ratio of 40,000:1 and have a surface sheath of SiO2.

High aspect ratio cellulose nanofilaments and method for their production

A novel method is disclosed to produce on a commercial scale, high aspect ratio cellulose nanofilaments (CNF) from natural lignocellulosic fibers. The method consists of a multi-pass high consistency refining (HCR) of chemical or mechanical fibers using specific combinations of refining intensity and specific energy. The CNF produced by this invention represents a mixture of fine filaments with widths in the submicron and lengths from tens of micrometers to few millimeters. The resultant product is made of a population of free filaments and filaments bound to the fiber core from which they were produced. The proportion of free and bound filaments is governed in large part by total specific energy applied to the pulp in the refiner. These CNF products differ from other cellulose fibrillar materials by their higher aspect ratio and the preserved degree of polymerization (DP) of cellulose. The CNF products made by this invention are excellent additives for the reinforcement of paper, tissue ...
