Description
Technical field
The present invention relates to belong to infant's series feeding bottle and glassware manufacturing technology field, mainly is a kind of making method of borosilicate glass auto-mechanism series feeding bottle.
Background technology
Existing feeding bottle major part is plastics feeding bottle and glass feeding bottle two big classes;
The plastics feeding bottle belongs to organic polymer material, can not stand high temperature for a long time, so the unsuitable boiling high-temperature sterilization of this feeding bottle; Life-time service material itself is prone to aging and discharges harmful material; This material adds softening agent (fluidizer) during fabrication, and because of softening agent contains phthalate fluidizer composition, its composition effect is similar to artificial hormone; Can endanger male reproductive function and impel women's sexual prematurity, long-term huge uptake can cause liver cancer.Because the child is in the endocrine system reproductive system growth period, the potential hazard that DEHP brings the child can be bigger; This feeding bottle poor transparency is unfavorable for cleaning and observes in addition.
The glass feeding bottle has soda-lime glass feeding bottle and borosilicate glass feeding bottle at present; Soda-lime glass feeding bottle feeding bottle poor chemical stability; Life-time service can produce flake; Can be absorbed by the body gets into blood and forms thrombus, also has lime glass emergency heat and cooling property resistance chilling ability, can not the high temperature steaming sterilization or meet cold and hot water and be used alternatingly easy explosion; The borosilicate glass feeding bottle all uses the borosilicate glass tube secondary processing to process at present, and repeatedly repeated heating is to 800-1100 ℃ when secondary processing for Glass tubing, and this temperature is phase-splitting, the crystallization point of this material; Change so arrange, chemistry, the physicals of its material itself are changed and reduce its use properties greatly, and approach the soda-lime glass performance at the microcosmic molecular structure of course of processing glass material itself; This feeding bottle uses Glass tubing secondary bottom sealing method to make bottle end, and the feeding bottle bottle base thickness degree that this method is made is less than 0.5mm, bottle end bad mechanical strength; Use is prone to explosion; Potential safety hazard is big, and this method all uses efficient hand-manipulated extremely low, basically all adopts the Glass tubing of market circulation in addition at present; The Glass tubing quality is mixed the genuine with the fictitious, and causes the feeding bottle difficult quality guarantee.
Summary of the invention
The object of the invention will overcome the deficiency of above-mentioned technology just, and the disposal molding method of manufacture that provides the making method, particularly borosilicate glass of a kind of borosilicate glass auto-mechanism series feeding bottle to found feeding bottle from raw material.
The present invention solves the technical scheme that its technical problem adopts: the making method of this borosilicate glass auto-mechanism series feeding bottle steps of the method are:
(1), according to the various raw materials of the accurate weighing of borosilicate glass composition requirement (can adopt conventional formulation), pour mixer successively into and mix, it is 95% subsequent use that mixture homogeneity arrives;
(2), borosilicate glass found, and the even constant speed of frit that weighing accurately mixes is put into high temperature melting in the all-electrical glass melting kiln, temperature of fusion 1550-1600 ℃, fusing time 14-24 hour; Through clarification, remove the bubble that raw material produced in the pyroreaction stage, 1600-1670 ℃ of clarification zone temperatures, settling time 8-12 hour; To not have bubble glass liquid and carry out homogenizing at the homogenizing layer, this zone temperatures is 1500-1580 ℃, 3-5 hour homogenizing time;
(3), glass metal temperature adjustment feed; The glass metal that fusing is qualified carries out the temperature adjustment to reach the temperature that the feeding bottle moulding needs at the glass supply channel; The feeding bottle mold temperature is 1200-1250 ℃, by the automatic feeding machine of glass metal glass metal is processed regulation shape and predetermined weight;
(4), the feeding bottle moulding is made; With glass gob automatic disposal molding on shaper of feeding machine supply is the feeding bottle shape; Glass is separated by water vapour air cushion and mould in mould, and cushion depth remains on 0.1mm, and makes glass constantly rotation in mould; Feeding bottle moulding speed of rotation is 5-8r/min, keeps the surface-brightening of feeding bottle not have mould trace and the bad mold joint vestige of eliminating mould;
(5), the smart circle of contact mouth of feeding bottle, with the feeding bottle blank after the moulding on cold quick-fried machine feeding bottle more than glass cut away, make bottleneck smooth, smooth, mellow and full;
(6), feeding bottle anneal; In the airtight dustless continuous annealing furnace of hot air circulation, feeding bottle is carried out anneal, eliminate the glass feeding bottle, make the stress of feeding bottle even in the thermal stresses that production process produces; This feeding bottle annealing temperature was 600-650 ℃, through annealing in 120 minutes.
As preferably, hundred kilograms of glass metal composition of raw materials are following: silica sand 70-80 KG, white lake 4.0-5.5 KG; BORAX PENTAHYDRATE-99.9MIN 18-25 KG, boric acid 8-10 KG, refined salt 4-5 KG; BORAX PENTAHYDRATE-99.9MIN and BORAX DECHYDRATE 99.5Min are the benchmark introducing that can convert each other with the introducing amount of B2O3; Aluminum oxide and white lake are the benchmark introducing that converts each other with the introducing amount of AL2O3, and the introducing ratio is that a BORAX PENTAHYDRATE-99.9MIN is equal to 1.31 parts of BORAX DECHYDRATE 99.5Mins, and a aluminum oxide is equal to and 1.53 parts of white lakes.
The effect that the present invention is useful is: the some serial feeding bottle glass transparent degree of the present invention are good, the appearance light, and no match mark is easy to clean inspection; But the high temperature steaming sterilization is not also broken with cold water cooling use immediately, can in microwave oven, heat use yet; Chemicalstability is good, and life-time service can not have any reaction with water, acid, alkaloid substance.
