Description
Во МНОГИХ случа х необходи1мо, чтобы клей после высыхани образовывал гибкую элас ичную пленку . В частности, это касаетс костного кле , примен емого дл заклейки корешков книжных блоков.In many cases, it is necessary that the glue, after drying, form a flexible elastic film. In particular, this concerns the bone glue used to glue the roots of book blocks.
Дл придани эластичности заклеенному корешку обычно к.тей готов т по следующей рецептуре: кле костного глицерина 7% и воды 50%.In order to give elasticity to a sealed root, usually the candies are prepared according to the following recipe: bone glycerin glue 7% and water 50%.
Однако глицерин в этой рецептуре вл етс лишь пластификатором . Глицерин оказывает на клеевую пленку лишь временное см гчающее действие; он постепенно испар етс и клеева пленка снова становитс хрупкой.However, glycerin in this formulation is only a plasticizer. Glycerin has only a temporary softening effect on the adhesive film; it gradually evaporates and the adhesive film again becomes brittle.
Предлагаемый способ приготовлени ГЛЮТИНОВОГО кле очличаетс тел1, что в состав клеющего раствора ввод т мочевину в соотношении примерно 1 части мочевины на 7 частей сухого животного кле .The proposed method for the preparation of GLUTIN glue is tel1, that urea is added to the adhesive solution in a ratio of about 1 part urea to 7 parts of dry animal glue.
Глютиновый клей готов т по следующей рецептуре: кле костного 35%, мочевины 5% и воды 60«/о.Glutinium glue is prepared according to the following recipe: bone adhesive 35%, urea 5% and water 60 "/ o.
Сначала костный клеи развод т в воде при температуре около 70, а затем добавл ют мочевину и размешивают.Bone adhesives are first diluted in water at a temperature of about 70, and then urea is added and stirred.
Применение мочевины взамен глицерина позвол ет получать более эластичнзю клеевую пленку, устойчивую к хранению и обладаюш;ую достаточной механической прочностью. Мочевлна при хранении CK.ieeiiHHX пpeд:v eтoв не испар етс и к.чеевой шов кл.ч клеевое покрытие все врем остаетс эласт 1чны .м. Кроме тою, клей с мочевино ; лучше проникает между тетрад ми к гижпого блока, благодар чему прочность скренлени корешков книг увеличиваетс .The use of urea instead of glycerol allows to obtain a more elastic adhesive film that is resistant to storage and has sufficient mechanical strength. Urea when storing CK.ieeiiHHX Prev: v The trees do not evaporate and the collar is cool and the adhesive coating remains elastic for 1 hour. M. In addition to this, glue with urea; it penetrates better between the notebooks to the gijp block, due to which the ridging strength of the book roots increases.
Предмет изобретени Subject invention
Способ при1-отовлени глютинового 1сле , о т л и ч а ю щ и .ч с тем, что, с целью улучшени эластических свойств клеевой пленки, в состав клеюптего раствора ввод т мочевину в соотношении примерно 1 части мочевины на 7 частей СУХОГО животного кле .The method of priming gluten by 1sl, ohl and h and y and h so that, in order to improve the elastic properties of the adhesive film, urea is introduced into the composition of the glue solution in a ratio of approximately 1 part urea to 7 parts of DRY animal glue .
