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 гипсовых плит, предполагающий использование массы, включающей, мас.ч.: воду 700; макулатуру 15; двуводный гипс или фосфогипс 85; мочевиноформальдегидная смола 5; крахмал 2,5 [1].A known method of producing gypsum boards, involving the use of mass, including, parts by weight: water 700; waste paper 15; gypsum gypsum or phosphogypsum 85; urea-formaldehyde resin 5; starch 2.5 [1].
Задача изобретения состоит в повышении прочности гипсовых плит, полученных из массы.The objective of the invention is to increase the strength of gypsum boards obtained from the mass.
Технический результат достигается тем, что масса для производства гипсовых плит, включающая воду, макулатуру, двуводный гипс или фосфогипс, мочевиноформальдегидную смолу, крахмал, дополнительно содержит распушеное асбестовое волокно при следующем соотношении компонентов, мас.ч.: вода 680-720; макулатура 20-25; двуводный гипс или фосфогипс 83-87; мочевиноформальдегидная смола 4-4,4; крахмал 1-1,4; распушеное асбестовое волокно 2-2,5.The technical result is achieved in that the mass for the production of gypsum boards, including water, waste paper, two-water gypsum or phosphogypsum, urea-formaldehyde resin, starch, additionally contains fluffy asbestos fiber in the following ratio of components, parts by weight: water 680-720; waste paper 20-25; gypsum gypsum or phosphogypsum 83-87; urea-formaldehyde resin 4-4.4; starch 1-1.4; fluffed asbestos fiber 2-2.5.
В таблице приведены составы массы для производства гипсовых плит.The table shows the composition of the mass for the production of gypsum boards.
Компоненты дозируют в требуемых количествах. В процессе приготовления массы для производства гипсовых плит используют гидропушитель, в который подают воду, макулатуру, предварительно нарезанную на куски площадью 2-16 см2. После распушивания макулатуры образовавшуюся массу перекачивают в емкость, где ее перемешивают в течение 10-15 мин с распушеным асбестовым волокном (5, 6 сорт), двуводным гипсом или фосфогипсом, мочевиноформальдегидной смолой и крахмалом. Затем массу обезвоживают, формуют из нее плиты, которые сушат при температуре 70-75°С.The components are dosed in the required amounts. In the process of preparing the mass for the production of gypsum boards, a hydrofoil is used, into which water, waste paper, previously cut into pieces with an area of 2-16 cm 2 , is supplied. After fluffing up the waste paper, the resulting mass is pumped into a container, where it is mixed for 10-15 minutes with fluffed asbestos fiber (5, 6 grades), two-water gypsum or phosphogypsum, 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.
Прочность гипсовых плит, полученных из предложенной массы, повышается на 10-15% в сравнении с плитами, изготовленными с применением массы [1].The strength of gypsum boards obtained from the proposed mass is increased by 10-15% in comparison with plates made with the use of mass [1].
