Mistoqsijiet riċenti tal-Klijent QA
Mar 10, 2022
Wara perjodu ta’ għażla, għal darb’oħra ġbarna xi feedback mingħand il-klijenti u għamilna artiklu biex jaqra kulħadd.
Q1: Għaliex iż-żirkonja tiegħek hija ħadra wara s-sinterizzazzjoni?
A1:It is because your finance has been polluted, different types of zirconia have different subsidiary substances during production. when sintering the substance will get rid of zirconia and come to the heart of finance, it made the heart of finance was polluted because the substance doesn't get rid of completely.
Pls, sinter the finance empty immediately to help the substance get rid of completely. Each time sintering the heating elements will have new crystalline film. It is better to change the sintering tray and beads as well.
Suġġerimenti biex tevita t-tniġġis:
1, M'għandekx sinter tipi differenti ta 'zirconia kontinwament.
Per eżempju, illum sinterizzazzjoni blokki bojod, jekk għada għandek bżonn sinter pre sfumaturi blokki, għandek sinterizzazzjoni tal-finanzi vojta wara blokki bojod imbagħad sinter pre sfumaturi.
2, Il-kuruni tal-blokki bojod kollha għandhom jinxfu 200 grad 30 minuta qabel is-sinterizzazzjoni
Q2: X'inhi d-differenza bejn SHT Multilayer u 3D-Plus Multilayer?
A2: SHT huwa gradjent tal-kulur. Is-saħħa hija 1200MPA u 45 fil-mija trasluċenza.
3D-Plus huwa kemm gradjent tal-kulur kif ukoll tas-saħħa. Qawwa minn 600MPA sa 900MPA, trasluċenza minn 43 fil-mija għal 49 fil-mija.
Sadanittant, Qed nittestjaw 3D ġdid E-Plus, Qawwa tista 'tkun Max 1100 u trasluċenza minn 47 fil-mija għal 49 fil-mija .
Q3: Ksur Pontine wara l-glazing?
A3: Hemm żewġ possibbiltajiet għal din il-problema:
1. The upper gingival porcelain requires repeated enamels, and the burned bridge undergoes multiple heating and cooling. Pulling and cracking are caused by the too fast cooling rate.
Suggestions: Lower the cooling rate and reduce the number of times porcelain loading
Porcelain furnace cooling program should be set a little slower, porcelain furnace cooling too fast will cause thermal stress, thermal shock, ceramics are most afraid of rapid cooling and heating, porcelain furnace cooling down a little bit, the lower temperature limit is set a little lower
This needs to be paid attention to in the porcelain furnace, the mouthful of rapid cold causes thermal stress cracking
Generally, the teeth in the porcelain furnace come out at 700 degree and come into contact with the air, and the teeth at 700 degree encounter the cold air at 25 degree , which causes cracking.
Easiest to break from the missing position, because the missing position is solid, accumulates more heat, and dissipates slowly
2. When the porcelain is cut, the teeth are cut vertically with fine slices. (In the past, metal teeth and porcelain teeth were cut in this way, so technicians are used to it).
Suggestion: When the car porcelain is cut between the teeth, it should be cut sideways in the direction of the teeth. However, this possibility is generally small.
