Makhalidwe a Condensation-Cure Mold Silicone
M'dziko losinthasintha la kupanga nkhungu, kusankha kwa silikoni kumakhala ndi gawo lofunikira pozindikira mtundu, kulondola, komanso kusinthasintha kwa chinthu chomaliza.Silicone yochizira nkhungu yochiritsa, yosiyana ndi banja la silikoni, imapereka zinthu zingapo zomwe zimapangitsa kuti ikhale chisankho chokondedwa pamapulogalamu ambiri.Tiyeni tifufuze zapadera zomwe zimasiyanitsa silicone yochiritsa nkhungu.
1. Njira Yosakaniza Yosakaniza ndi Kuchiritsa: Silicone yochizira nkhungu ya condensation ndi zigawo ziwiri, zomwe zimakhala ndi silicone ndi mankhwala ochiritsira.Kusakaniza koyenera ndi magawo 100 a silicone kupita ku magawo awiri ochiritsa polemera.Kuphweka kwa ntchito kumapangitsa kusakaniza koyenera, ndi nthawi yovomerezeka yogwira ntchito ya mphindi 30.Kutsatira kusakaniza, silikoni imatenga nthawi yochiritsa kwa maola 2, ndipo nkhungu imakhala yokonzeka kugwetsedwa pakatha maola 8.Chofunika kwambiri, kuchiritsa kumachitika kutentha kwapakati, ndipo kutentha sikuvomerezeka.
2. Semi-Transparent and Milky White Variants: Silicone yochizira nkhungu ya condensation imapezeka m'mitundu iwiri - yowoneka bwino komanso yoyera yamkaka.Silicone yowoneka bwino imatulutsa nkhungu zokhala zosalala, pomwe zoyera zoyera zamkaka zimawonetsa kukana kutentha kopitilira 100 digiri Celsius.Kusinthasintha kumeneku kumapangitsa kusankha kwa mtundu wa silicone womwe umagwirizana bwino ndi zomwe mukufuna kugwiritsa ntchito.
3. Zosankha Zosiyanasiyana: Kuuma kwa silicone ya condensation-cure mold kumaperekedwa mu sipekitiramu kuyambira 10A mpaka 55A.Mtundu wa 40A/45A, wodziwika ndi mtundu wake woyera wamkaka, ndi silikoni yolimba kwambiri, pomwe mtundu wa 50A/55A umapangidwa mwapadera kuti upangire zitsulo zotsika zosungunuka ngati malata.Kuuma kosiyanasiyana kumeneku kumakwaniritsa zosowa zosiyanasiyana zomangira, kupereka kusinthasintha komanso kulondola.
4. Mawonekedwe Osinthika: Silicone yochiritsa nkhungu imawonetsa kutentha kwa chipinda kuyambira 20,000 mpaka 30,000.Nthawi zambiri, pamene kuuma kumawonjezeka, momwemonso mamasukidwe akayendedwe.Kutha kusintha mawonekedwe a viscosity kumatsimikizira kuti silikoni imatha kupangidwa kuti ikwaniritse zofunikira zenizeni, ndikupereka yankho lamitundu ingapo yamaumba.
5. Organic Tin Cure and Catalysis: Imadziwikanso kuti organic tini-cured silicone, silikoni yochiritsa nkhungu imakhala ndi sulfurization reaction yopangidwa ndi organic tini chothandizira pakuchiritsa.Chigawo cha wothandizira wochiritsa nthawi zambiri chimachokera ku 2% mpaka 3%.Njira yochiritsa ya tini iyi imathandizira kukhazikika ndi kudalirika kwa njira yochiritsa.
6. Transparent kapena Milky White Liquid Form: Silicone yochiritsa nkhungu ya condensation nthawi zambiri imakhala yoyera kapena yamkaka yoyera.Kusinthasintha kwa silikoni iyi kumafikira pakusintha mitundu, pomwe ma pigment amatha kuwonjezeredwa kuti apange nkhungu zamitundu yosiyanasiyana, ndikuwonjezera kukongola kwa chinthu chomaliza.
7. Ntchito Zopanda Poizoni ndi Zosiyanasiyana: Chochititsa chidwi ndi kawopsedwe kakang'ono ka silicone yochiritsa nkhungu, ndikupangitsa kuti ikhale yabwino kwa ogwiritsa ntchito.Zikhungu zopangidwa pogwiritsa ntchito silikoni iyi zitha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana, kuphatikiza gypsum, paraffin, epoxy resin, unsaturated resin, polyurethane AB resin, simenti, ndi konkriti.
Pomaliza, silikoni yochizira nkhungu imadziwika bwino kwambiri popanga nkhungu chifukwa chakusakanikirana kwake ndikuchiritsa, kuuma kwake, kusinthika kwa viscosity, makina ochizira organic tini, komanso kusinthasintha pamagwiritsidwe ntchito.Monga madzi owoneka bwino kapena amkaka oyera, silikoni iyi imapereka chinsalu chosinthira mwamakonda, kulola kuti pakhale zisankho zomwe zimakwaniritsa zokongoletsa komanso magwiridwe antchito.Ndi chikhalidwe chake chopanda poizoni, kugwiritsa ntchito mosavuta, komanso kugwirizanitsa ndi zipangizo zosiyanasiyana, silicone yochiritsira nkhungu ikupitiriza kukhala chisankho chodalirika kwa amisiri ndi opanga m'mafakitale osiyanasiyana.
