Mpira wa Tin Silicone wa Utomoni Wopanga Zojambula Kupanga Zithunzi Zowoneka

Mpira wa Tin Silicone Wopanga Utomoni Wopanga Ma Molds

Kufotokozera mwachidule:

Njira zopangira zojambulajambula za pulasitala ndi silicone yamadzimadzi nkhungu ndi izi:

Tsukani nkhungu zazikulu ndikupoperapo zotulutsa kuti zisamamatire.
Gwiritsani ntchito zomangira kuti muzungulire chimango molingana ndi kukula kwa nkhunguyo.Nthawi zambiri, ndi 1 mpaka 2 centimita wamkulu kuposa nkhungu.Kwa nkhungu zopepuka komanso zazing'ono, guluu liyenera kugwiritsidwa ntchito kuti liwakonzere kuti apewe manyazi a nkhungu yoyandama atadzaza ndi guluu.
Yezerani kuchuluka koyenera kwa nkhungu yamadzimadzi a silicone molingana ndi kukula kwa nkhungu, onjezerani mankhwala ochiritsa moyenerera, ndiyeno gwedezani bwino.
Thirani madzi osakaniza a silicone mu nkhungu, makamaka kuphimba kutalika kwa nkhungu ndi 1 mpaka 2 cm.
Pambuyo podzaza guluu, ikani pamalo okhazikika ndikudikirira kuti ikhale yolimba.
pulasitala ikalimba, chotsani zomangira ndikuzitulutsa.

Mawonekedwe a silicone mold condensation

1. Gelisi wa silika wa condensation amagawidwa m'magawo awiri: gel osakaniza ndi machiritso.Pa ntchito, sakanizani ziwiri molingana ndi kulemera kwa chiŵerengero cha silika gel osakaniza ndi kuchiritsa wothandizila 100:2 ndi kusonkhezera wogawana.Nthawi yogwiritsira ntchito ndi mphindi 30 ndipo nthawi yochiritsa ndi maola a 2, imatha kugwetsedwa pambuyo pa maola 8 ndipo imatha kuchiritsidwa kutentha popanda kutentha.

2. Silicone ya condensation imagawidwa m'magulu awiri: yoyera komanso yoyera yamkaka: nkhungu yopangidwa ndi silikoni yowonongeka imakhala yosalala, ndipo nkhungu yoyera yamkaka imatha kupirira kutentha kwambiri kuposa madigiri 100 Celsius.

3. Kuuma kwa gel osakaniza silika ndi 10A/15A/20A/25A/30A/35A, 40A/45A ndi mkaka woyera high-hard silika gelisi, ndipo 50A/55A ndi super-hard silika gel, amene makamaka ntchito nkhungu. kutembenuka kwa malata, lead ndi zitsulo zina zotsika zosungunuka.

4. Yachibadwa kutentha mamasukidwe akayendedwe a condensation silika gel osakaniza ndi 20000-30000.Nthawi zambiri, kuuma kwapamwamba, kumapangitsanso kukhuthala kwamphamvu.Ikhozanso kusinthidwa makonda.

5. Condensation silika gel amatchedwanso organotin kuchiritsa silica gel.Panthawi yogwira ntchito, vulcanization imachitika kudzera mu chothandizira cha organotin.Chiŵerengero cha machiritso ndi 2% -3%.

6. Gelisi ya silika ya condensation ndi madzi owonekera kapena madzi oyera amkaka.Nkhumba zimatha kuwonjezeredwa kuti mupange mtundu uliwonse.

7. Condensation silika gel osakaniza si sachedwa poyizoni zochita, ndipo zisamere pachakudya zopangidwa angagwiritsidwe ntchito kupanga zinthu monga gypsum, parafini, epoxy utomoni, unsaturated utomoni, polyurethane AB utomoni, simenti konkire, etc.
