Praecipuae factores quae calorem signantes robur aluminii ffoyle medicamentis packaging affectantes sunt:
1. Rudis et auxilia materiae
Aluminium originale ffoyle est gerulus tenaces iacuit, et ejus qualitas magnam vim habet in vi sigilli caloris producti. Praesertim, maculas olei in superficie aluminii originalis foil, adhaesionem inter tenaces et aluminium ffoyle hebetabit.. If the surface of the original aluminum foil is oily and the surface tension is lower than 31×10-3μm, difficile est consequi exemplar vires sigillum calor, so the quality of the original aluminum foil must be strictly controlled.
Insuper, during the production process, it was discovered that certain batches of original aluminum foil with all technical indicators meeting the requirements were coated with adhesives under all process conditions, but the heat seal strength of the final product could not reach The reason is that the metal composition and surface brightness of the original aluminum foil are not enough. The research results show that by changing a special link to make full use of the original aluminum foil, the product reaches the ideal heat-seal strength.
2. Adhesives
Tenaces est substantia specialis continens solvendo. IIT est adoperta (aut lenis) of the original aluminium ffoyle under certain process conditions, et siccatur in sicco cuniculo ad formam tenaces iacuit, which is decisive for the heat seal strength of the product effect. Adhesives can be divided into colorless, transparent, golden and colored series in color, which can be selected according to the needs of users. Adhesives of different components have different heat seal strengths in the final product. Most domestic manufacturers use imported raw materials to prepare adhesives, and the products can achieve high heat seal strength. tamen, rudis materiae pretium importari nimis pretiosa. Ad obtinendum magna fructus fructus, quidam artifices cum validis facultatibus investigationis scientificae inceperunt investigare et similes materiae rudis domesticas evolvere. This kind of research direction is very tempting, if it can be successful, it will bring huge benefits to the enterprise. It is understood that due to the limited process of domestic raw material manufacturers, domestic raw materials cannot replace imported raw materials to a large extent. If used improperly, it will seriously affect the heat seal strength of the product.
3. Processus productio
Sub ambitu parametri cuiusdam, tenaces in superficie originali aluminium ffoyle obductis ad formare film. The quality of the film will directly affect the heat seal strength of the product. Inter parametri maioris momenti celeritatem membranam includunt, articulata temperatus de siccitate cuniculi, figura, profundum, linearum numerus, et situs et angulus laminae efficiens cylindro.
Celeritas efficiens determinat desictionem temporis in siccitate cuniculi. Si celeritas efficiens nimis celeriter et siccitates cuniculi caliditas nimis alta est, the solvent on the surface of the coating film will evaporate too fast, resulting in solvent residues in the film, et membrana membrana satis arida non erit, et siccum erit difficile formare, fortis tenaces accumsan. It will affect the heat sealing strength and degree of the product, and cause adhesion between the product layers.
Anilox figura, profundum, numerus linearum et situs et angulus medici laminae crassitudinem et uniformitatem membranae membranae determinant. Si lectio vel temperatio est inconveniens, the adhesive cannot be evenly coated on the surface of the original aluminum foil, inde in inaequale film formation, and the heat sealing effect of the product will not be good, et vis etiam affici. According to the national standard adhesive layer coating, the difference should be less than ± 12.5%. Ergo, the process of coating the adhesive layer into a film must be completed in strict accordance with the parameters specified by the process to ensure the uniformity and firmness of the film.
4. Æstus signantes temperatus
Calor-signatio temperatus magni momenti est quod vim caloris signandi afficit. Si temperatus nimis, ad tenaces iacuit non potest esse calor-signata cum PVC film bene, et vinculum inter stratum tenticum et PVC pellicula non est fortis. Si temperatus est nimis alta, in medicina voluntas affectus. Ergo, rationabilem caloris signationem temperatus plerumque inter CL ° C et CLX ° C *.
5. Æstus signantes pressura
Ad consequi exemplar roboris æstus signantes, quaedam calor signationem pressura esse debet. Si pressura est insufficiens, non solum iacuit tenaces producti et pelliculae PVC non possunt plene religata et obsignata calori, but also air bubbles will remain between the two, failing to achieve a good heat sealing effect. Ergo, the national standard stipulates that the heat sealing pressure is 0.2×10Pa.
6. Æstus signare tempus
Tempus caloris signandi etiam afficit caloris signandi robur producti. In rebus communibus, sub eodem calore signantes temperatus et pressura, calor enim longiori signandi temporis potest facere partem caloris signatam firmius et perfectius obsignari, et melius potest consequi spem caloris signandi vires. tamen, the technological conditions of modern high-speed medicine packaging machines cannot provide a long time for heat sealing. Si calor signationem tempus angustum est, aestus obsignatio inter stratum tenticum et PVC cinematographicum insufficiens erit. quamobrem, vexillum nationale statuit quod scientificum caloris signationem tempus sit 1s.
