Примен емое до насто щего времени определение степени распушки асбеста но объему осадка 0,5% асбестовой суспенвни, образующегос Б литровом цилиндре после 30-минутного отстаиваНИ , отличаетс продолжительностью процесса измерени практически исключающей оперативное вмешательство в технологию обработки асбеста, а также илохо воспроизводимостью Показаний, завпс п1ей от субъективных cpaiKTOpoB (ручное взбалтьжание ),.от наличи воздущных пузырьков в воде . KpOiMe того, метод непригоден дл асбестов н:екоторых ,местО(рожде№ий.The determination of the degree of asbestos fuzz but up to a sediment volume of 0.5% asbestos suspension, which forms a B liter cylinder after 30 minutes of settling, used up to the present, differs in the duration of the measurement process, which practically excludes surgical intervention in the technology of asbestos treatment, as well as the reproducibility of indications, and from subjective cpaiKtopoB (manual agitation), from the presence of air bubbles in the water.

|Предлагаетс слособ определени степени раопущки волокнистого материала, например асбеста, отличающийс тем, что измер ют предельное напр жение сдвига волокнистоводной суспензии.A method is proposed for determining the degree of filament of a fibrous material, such as asbestos, characterized in that the shear stress of the fibrous suspension is measured.
Реализаци способа по сн етс схемой.The implementation of the method is illustrated by the scheme.
Дл воспроиЗБОДИмости условий измерений задают определенные по значению концентрацию и объем суспензии.For reproducibility of the measurement conditions, the concentration and volume of the suspension determined by value are set.
Жидкую суспензию контролируемого волокна заливают в V-образную стекл нную трубку / через BOipoHKy 2.The liquid suspension of the controlled fiber is poured into a V-shaped glass tube / via BOipoHKy 2.
Одно колено V-образной трубки соедин ют с вентилем 3 и резиновой грушей 4 при помо2One knee of the V-shaped tube is connected to the valve 3 and the rubber bulb 4 with help
щи резинового шланга 5. Второе колено открыто и сообщаетс с атмосферой. С по.мощью резиновой груши создают давление, которое поднимает суспензию в другом ко.тене, затем, открыв вентиль 4, снижают давление до атмосферного.rubber hose 5. The second knee is open and communicates with the atmosphere. With the help of a rubber pear, they create pressure, which raises the suspension in another co-ring, then, by opening valve 4, reduce the pressure to atmospheric.
Суспензи пр.и этом медленно перемещаетс , опуска сь не до нулевой отметки, как это было бы при ньютоновской жидкости по закону сообщающихс сосудов, а до определенного уровн , образу перепад Н. величина которого пропорциональна статическому предельному нанр жению сдвига 0.The suspension is then slowly moving, dropping not to the zero mark, as would be the case with Newtonian fluid according to the law of communicating vessels, but to a certain level, to form the H drop, the value of which is proportional to the static limiting shift of 0.
:Показа 1:и прибора по линейной шкале (в сантиметрах) служат мерой предельного напр жени сдвига суспензии и лропор.циоиальпы дисперсности волокна или степени оасплшки.: Display 1: and the instrument on a linear scale (in centimeters) serves as a measure of the ultimate shear stress of the suspension and of the dispersion of the fiber or the degree of dispersion of the fiber.
