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.
