Description
Изобретение относитс к способам получени веществ, обладающих кле щими свойствами на основе технических лигносульфонатов, вл ющихс основной частью отработанных суль- фитных Е1;елоков, дл использовани в нроизводстве древесно-волокнистых ШП1Т (ДВП) .The invention relates to methods for producing substances with adhesive properties based on technical lignosulphonates, which are the main part of spent E1 sulphate esters, for use in the manufacture of fiberboard SHP1T (DVP).
Цель изобретени - повышение физико-механических показателей дре- весно-волокнистьк плит.The purpose of the invention is to improve the physico-mechanical properties of wood-fibering plates.
Пример (по известному способу). К сульфитному отработанному щелоку добавл ют, %: щелок 6 (от сухого вещества); бихромат кали 5; хлорное железо 5; бура 2. После пер меш1 ванн щелока хлорируют до содержани хлора 4%. Прочность полученного продукта 7,0 кг/см . Показател плит, полученных с применением дан- иого. св зующего: сопротивление изгибу 10,0 1 Ша; водопоглощение 45%; набухание 42%.Example (by a known method). To the sulphite waste liquor is added,%: liquor 6 (from dry matter); potassium dichromate 5; ferric chloride 5; borax 2. After the permeable bath liquor is chlorinated to a chlorine content of 4%. The strength of the obtained product is 7.0 kg / cm. The index of the plates obtained using this data. binder: bending resistance 10.0 1 Sha; water absorption 45%; swelling of 42%.
П р II м е р 2. Концентрат сульфитно-дрожжевой бражки подогревают до 40°С, ввод т при перемешиварши 0,5% соды и 2,5% буры и продолл ают перемешивание при данной темнератур 80 мин. Через 20 ч продукт испытывают на прочность, котора равна 5,5 кг/сы. Показатели плит, полученых с применением данного св зующег сопротивление изгибу плит 260 кг/см водопоглощепие 38%; набухание 35%.Example II The sulphite-yeast brewer's concentrate is heated to 40 ° C, 0.5% soda and 2.5% borax are added with mixing, and the mixing is continued at this temperature for 80 minutes. After 20 hours, the product is tested for strength, which is 5.5 kg / sy. The performance of the plates obtained using this binder bending resistance of the plates 260 kg / cm water absorption 38%; swelling of 35%.
П р II е р 3. Концентрат сульфи но-дролсжевой бражки подогревают до 100 С и ввод т в пего при перемешивании 2,5% соды и 0,5% буры. Перемешивание при данной температуре про- доллсают 20 мин. Прочность получен- ного св зующего 6,4 кг/см. Показатели плит, полученных с применением данного св зующего: сопротивление изгибу 240 кг/см ; водопоглощение 37%; набухание 38%.PR II e p 3. The sulfide concentrate concentrate is heated to 100 ° C and, with stirring, 2.5% soda and 0.5% borax are added to it. Stir at this temperature for 20 minutes. The strength of the binder obtained is 6.4 kg / cm. The performance of the plates obtained with the use of this binder: bending resistance 240 kg / cm; water absorption 37%; swelling of 38%.
