Silifiyodenomerndi emulsion yoyera. Yagwiritsidwa ntchito m'minda yosiyanasiyana ya mafakitale kuyambira 1960s, koma akulu ndi akulu ndikukula bwino kwambiri adayamba m'ma 1980s. Monga chilengedwedenomer, minda yake yofunsira ilinso lalikulu kwambiri, yokopa kwambiri kuchokera kwa onse oyenda moyo. Mu mankhwala, pepala, zokutira, chakudya, kapangidwe ka mankhwala ogulitsa ndi magawo ena a mafakitale, siliconedenomerndizowonjezera zomwe zingachitike pakupanga. Sizingachotse chithovu pamadzimadzi pang'onopang'ono pakupanga, potengera kuwongolera, kuthira, ndi madzi osokoneza bongo, kuwuma ndi mapangidwe ena aukadaulo onetsetsani kuti kuthekera kwa zinthu zosiyanasiyana zosungira ndi kukonza zonyamula.

Zabwino zaDeforcoams:
1. Maupangiri osiyanasiyana: Chifukwa cha kapangidwe kake ka mankhwala a silika, sikugwirizana ndi madzi kapena zinthu zomwe zimakhala ndi magulu polar, kapena ndi ma hydrocarbons kapena zilombo zomwe zimakhala ndi magulu a hydrocarbon. Chifukwa cha kusungunuka kwa mafuta a silicane ku zinthu zosiyanasiyana, ali ndi mapulogalamu angapo. Itha kugwiritsidwa ntchito popewa m'madzi amadzi komanso m'mafuta amafuta.
2. Matenda otsika mtengo: Mafuta a silika nthawi zambiri amakhala 20-25 dy dm / cm, yomwe ndi yaying'ono kuposa yamadzi (72 dyne / cm) ndi magwiridwe antchito.
3. Izi zimatsimikizira kutiSicnone decomeritha kugwiritsidwa ntchito pamtunda wambiri.
4. Chifukwa chake, bola ngati kutupa kuli koyenera,decomes a silinayiamaloledwa kugwiritsidwa ntchito mu machitidwe okhala ndi acid, alkali, ndi mchere.
5. Chonchodecomes a silinayi.
6.Sicnone decomersangathe kuthyola chithovu chomwe chapangidwa, komanso chitha kulepheretsa chithovu ndikuletsa mapangidwe a chithovu. Kugwiritsa ntchito kwake ndi kochepa kwambiri, bola ngati kuwonjezera gawo limodzi pamiliyoni (1ppm) ya kulemera kwa sing'anga ya thovu, imatha kubweretsa kusintha. Mtundu wake womwe umagwiritsidwa ntchito ndi 1 mpaka 100 ppm. Osangokhala otsika mtengo, komanso samadetsa vuto lomwe limasokonekera.

Zovuta zadecomes a silinayi:
a. Polysiloxane ndiwovuta kubala: Polysiloxane ndiwovuta kusungunuka m'madzi, omwe amalepheretsa kubalaku m'madzi. Wothandizira wobalalika ayenera kuwonjezeredwa. Ngati obalirawo amawonjezeredwa, emulsion idzakhala yokhazikika ndipo kusokonekera kudzasintha. Osauka, ndikofunikira kugwiritsa ntchito emulsilifer pang'ono kuti musinthe bwino komanso zokhazikika.
b. Silicone akusungunuka mafuta mafuta, zomwe zimachepetsa mphamvu zake mu dongosolo lamafuta.
c. Kutalika kwakutali kukana ndi osauka alkali kukana.
