Abstract
Description
Изобретение относится к области производства строительных материалов на основе гипсового вяжущего.The invention relates to the production of building materials based on a gypsum binder.
Известен способ производства плит из дигидрата сульфата кальция, предполагающий использование сырьевой смеси, включающей, мас.ч.: вода 700; макулатура 15; фосфогипс 85; мочевиноформальдегидная смола 5; крахмал 2,5 [1].A known method of production of plates from calcium sulfate dihydrate, involving the use of a raw mixture, including, parts by weight: water 700; waste paper 15; phosphogypsum 85; urea-formaldehyde resin 5; starch 2.5 [1].
Задача изобретения состоит в повышении прочности плит, полученных из сырьевой смеси.The objective of the invention is to increase the strength of the plates obtained from the raw mix.
Технический результат достигается тем, что сырьевая смесь для производства гипсовых плит, включающая воду, макулатуру, фосфогипс, мочевиноформальдегидную смолу, крахмал, дополнительно содержит молотое до удельной поверхности 4000-5000 см2/г стекло и капроновое волокно, нарезанное на отрезки 3-15 мм, при следующем соотношении компонентов, мас.ч.: вода 700-730; макулатура 25-30; фосфогипс 83-87; мочевиноформальдегидная смола 2,5-3; крахмал 1-1,5; молотое стекло 3-5; капроновое волокно 0,2-0,4.The technical result is achieved in that the raw material mixture for the production of gypsum boards, including water, waste paper, phosphogypsum, urea-formaldehyde resin, starch, additionally contains ground glass to a specific surface of 4000-5000 cm 2 / g and nylon fiber cut into 3-15 mm segments , in the following ratio of components, parts by weight: water 700-730; waste paper 25-30; phosphogypsum 83-87; urea-formaldehyde resin 2.5-3; starch 1-1.5; ground glass 3-5; nylon fiber 0.2-0.4.
В таблице приведены составы сырьевой смеси.The table shows the composition of the raw mix.
Сырьевую смесь получают следующим образом.The raw material mixture is prepared as follows.
1. Компоненты сырьевой смеси дозируют в требуемых количествах. В гидропушитель подают воду, макулатуру (предварительно нарезанную на куски площадью 2-16 см2), молотое до удельной поверхности 4000 см2/г тарное стекло, капроновое волокно, нарезанное на отрезки 15 мм, фосфогипс. После распушивания макулатуры образовавшуюся массу перекачивают в емкость, где ее перемешивают в течение 10-15 мин с мочевиноформальдегидной смолой и крахмалом. Затем массу обезвоживают, формуют из нее плиты, которые сушат при температуре 70-75°С.1. The components of the raw mix are dosed in the required quantities. Water, waste paper (pre-cut into pieces of 2-16 cm 2 ), ground glass to a specific surface of 4000 cm 2 / g container glass, nylon fiber, cut into 15 mm segments, phosphogypsum are supplied to the hydraulics dryer. After fluffing up the waste paper, the resulting mass is pumped into a container, where it is mixed for 10-15 minutes with urea-formaldehyde resin and starch. Then the mass is dehydrated, plates are formed from it, which are dried at a temperature of 70-75 ° C.
2. Компоненты сырьевой смеси дозируют в требуемых количествах. В гидропушитель подают воду, макулатуру (предварительно нарезанную на куски площадью 2-16 см2), молотое до удельной поверхности 5000 см2/г листовое стекло, капроновое волокно, нарезанное на отрезки 3 мм, фосфогипс. После распушивания макулатуры образовавшуюся массу перекачивают в емкость, где ее перемешивают в течение 10-15 мин с мочевиноформальдегидной смолой и крахмалом. Затем массу обезвоживают, формуют из нее плиты, которые сушат при температуре 70-75°С.2. The components of the raw material mixture are dosed in the required quantities. Water, waste paper (pre-cut into pieces with an area of 2-16 cm 2 ), ground glass to a specific surface of 5000 cm 2 / g sheet glass, nylon fiber, cut into 3 mm segments, phosphogypsum are supplied to the hydraulics. After fluffing up the waste paper, the resulting mass is pumped into a container, where it is mixed for 10-15 minutes with urea-formaldehyde resin and starch. Then the mass is dehydrated, plates are formed from it, which are dried at a temperature of 70-75 ° C.
