Rabara ya silikoni yokhala ndi thovu ndi mtundu wazinthu za mphira za silikoni zomwe zimakhala ndi thovu.
Ili ndi ntchito zabwino kwambiri monga kutchinjiriza kutentha, kutsekereza madzi, mayamwidwe owopsa komanso kutsekereza mawu. Rabara ya silikoni yokhala ndi thovu, chifukwa cha mawonekedwe ake otayirira, kutsika kwambiri, kachulukidwe kakang'ono komanso kuyamwa bwino kwa mafunde, imagwiritsidwa ntchito kwambiri m'magawo monga zamagetsi, kupanga mafakitale, zakuthambo ndi zomangamanga.
Zimagawidwa ndi njira ya thovu:
01 Mfundo yotulutsa thovu:Kutulutsa thovu kumachitika poyambitsa mpweya kapena zinthu zamadzimadzi zomwe zimatha kutentha (monga CO₂ / N₂ kapena zosungunulira zosungunulira-zotentha-zocheperako), ndipo ntchitoyi simakhudzanso kusintha kwa mankhwala. Ubwino: yunifolomu thovu kapangidwe, chosinthika kuwira kukula, ndi chilengedwe wochezeka. Kugwiritsa ntchito: Zogulitsa zomwe zimafunikira kwambiri kuti{4}}ziyeretsedwe komanso zifanane, monga-zisindikizo zowoneka bwino komanso zopaka mafuta-zachipatala.
02 Chemical foaming mfundo:Mankhwala opangira thovu amawonjezeredwa, ndipo mpweya wopangidwa ndi kuwonongeka kwawo (monga N₂, CO₂) umapanga thovu mu rabala. Ubwino wake: Njira yosavuta, yotsika mtengo, komanso yogwirizana ndi mizere wamba yopangira. Kugwiritsa ntchito: Zotchinjiriza zotenthetsera, zotsekemera-zotengera zoyamwa ndi zinthu zina zatsiku ndi tsiku komanso zamakampani.
