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; мочевиноформальдегидную смолу 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 снижении теплопроводности гипсовых плит, полученных из массы.The objective of the invention is to reduce the thermal conductivity 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 молотый известняк и суперпластификатор С-3 при следующем соотношении компонентов, мас.ч.: вода 680-720; макулатура 45-50; двуводный гипс или фосфогипс 50-55; мочевиноформальдегидная смола 4,8-5,2; крахмал 1,0-1,4; молотый известняк 5-6; суперпластификатор С-3 0,3-0,35.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 ground limestone and S-3 superplasticizer in the following ratio, wt.h .: 680-720 water ; waste paper 45-50; gypsum gypsum or phosphogypsum 50-55; urea-formaldehyde resin 4.8-5.2; starch 1.0-1.4; ground limestone 5-6; superplasticizer C-3 0.3-0.35.
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. Известняк размалывают до получения порошка с удельной поверхностью 3000-5000 см2/г и смешивают с двуводным гипсом или фосфогипсом. В процессе приготовления массы для производства гипсовых плит используют гидропушитель, в который подают воду, макулатуру, предварительно нарезанную на куски площадью 2-16 см2, и молотый известняк, смешанный с двуводным гипсом или фосфогипсом.The components are dosed in the required amounts. Limestone is ground to a powder with a specific surface area of 3000-5000 cm 2 / g and mixed with two-water gypsum or phosphogypsum. In the process of preparing the mass for the production of gypsum boards, a water extinguisher is used, into which water, waste paper, previously cut into pieces with an area of 2-16 cm 2 , and ground limestone mixed with two-water gypsum or phosphogypsum are used.
После распушивания макулатуры образовавшуюся массу перекачивают в емкость, где ее перемешивают в течение 10-15 мин с мочевиноформальдегидной смолой, суперпластификатором С-3 и крахмалом. Затем массу обезвоживают, формуют из нее плиты, которые сушат при температуре 70-75°С.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, C-3 superplasticizer and starch. Then the mass is dehydrated, plates are formed from it, which are dried at a temperature of 70-75 ° C.
Теплопроводность гипсовых плит, полученных из предложенной массы, снижается на 10-15% в сравнении с плитами, изготовленными с применением массы [1]. При этом утилизируется большое количество макулатуры.The thermal conductivity of gypsum boards obtained from the proposed mass is reduced by 10-15% in comparison with plates made with the use of mass [1]. At the same time, a large amount of waste paper is disposed of.
