The preparation method of glass enamel for above-mentioned leadless environment-friendly easy cut ampule, comprises the following steps:
(1) according to the component of base glaze, quartz sand, sodium carbonate, borax, calcium carbonate, zinc oxide, barium carbonate and aluminium hydroxide are mixed in mixing equipment, obtain admixtion;
(2) admixtion is founded in resistance furnace at 1260 ℃, made the complete melting of admixtion, obtain glass metal;
(3) glass metal is carried out to shrend and obtain glass frit;
(4) glass frit is put in fire ball grinding jar, and added a certain amount of water and ball to carry out wet-milling 35min, obtain glass paste;
(5) in baking oven, dry after glass paste is crossed to 250 mesh sieves, obtain glass powder, glass powder is put into the fire ball grinding jar 20min that dry grinds again, the powder obtaining after dry grinding is base glaze;
(6) base glaze and particle diameter are less than to the additional opacifying agent of 250 object and mix in mixer, obtain leadless environment-friendly easy cut ampule glass enamel; Wherein, the add-on of opacifying agent is 3% of base glaze quality.
During use, the glass enamel of preparation is mixed with Terpineol 350, obtain glaze slip, by scraper plate, on ampoule glass matrix, carry out glazing, be dried afterwards; By sending into glaze firing stove with the glass basis of glaze after dry, at 620 ℃, burn till.
The glass enamel performance comparison that embodiment of the present invention 1-7 is prepared:
The glaze firing result of table 1 embodiment 1-7
As can be seen from the above table, whiteness, the glossiness of the glass enamel of embodiment 5 preparations are all fine.
The invention provides a kind of can being applied in and on medical ampoule, play the technology that makes the easy to break and decoration functions of ampoule, on bent neck ampoule neck surface, be coated with one deck color glaze as thin as a wafer, owing to there being the difference of the coefficient of expansion between color glaze and ampoule, just can at the recess of ampoule neck, form concentrated stress, make ampoule be easy to fracture.This characteristic makes glass ampoule both easy to use, safety and sanitation again; Also can be used for preparing colored glazed glass.
If add 0～5%SnO of base glaze quality by a large amount of only experimental studies have found that with molten addition in base glaze system
2, 0～10%TiO
2time, opaque effect is not obvious; And by 2%～12%TiO of mill addition method additional base glaze quality in above-mentioned base glaze glass powder
2time, opaque effect is good.So the present invention adopts two additions, first melts and adds base glaze quality 5%TiO
2(or SnO
2) in base glaze, for improving specific refractory power and the glossiness of color glaze, regrinding, add the 10%TiO of base glaze quality
2opaque effect is best, and final temperature of glaze firing scope, between 580～660 ℃, meets the requirements.By whiteness instrument, to color glaze measuring brightness, can reach more than 75%.
