Silikoni mafuta: makhalidwe ndi ntchito

Silikoni mafuta amatanthauza gulu lonse la zinthu zimene ntchito muzochitika zosiyanasiyana za ntchito. Mawu akuti "silikoni" amatchedwa kuti gulu la mankhwala organosilicon. Iwo anachokera ku mayina a pakachitsulo mu tebulo nthawi ya zinthu ( «Silicium»).

Silikoni mafuta amatanthauza gulu la madzi silikoni ndi a mitundu yosiyanasiyana, amene kukhuthala osiyana, mpaka madzi kuundana ndi kuwira. mankhwala Amenewa alibe fungo ndi mtundu, kugonjetsedwa ndi madzi ambiri aukali zinthu thupi ndi mankhwala zosalemekeza zipangizo zina za chiyambi organic. Silikoni mafuta kutentha kugonjetsedwa ndi pafupifupi kupsereza. Iwo sizitithandiza kapena kusokoneza kwenikweni zipangizo monga pulasitiki, utoto, labala, zamoyo ndi zimakhala. Silikoni madzi ndi kwambiri magetsi zokutira zitsulo ndi katundu hydrophobic.

kuphatikiza katundu opindulitsa physicochemical chosowa kwambiri. Ichi ndi chifukwa kuti silikoni mafuta ndi zina zochokera mankhwala organosilicon ndi wa ukulu ngati waukulu.

ntchito zawo kuti yopanga: phula, yosiyanasiyana lubricants ndi zina kwa mafuta osiyana damper ndi madzi hayidiroliki ndi osiyanasiyana zinthu kutentha. Pophikira ndi makampani chakudya iwo ntchito popewa thobvu la sachedwa chifukwa ndi umatetezera.

Kwambiri woyeretsedwa wosabala silikoni mafuta chimagwiritsidwa ntchito mankhwala. Silikoni madzi amagwiritsidwa ntchito kwa impregnation nsalu ndi zovala zipangizo mwatsatanetsatane zida zosiyanasiyana, komanso mafilimu amene amafotokoza pamalo nsupa kwa kusungiramo mankhwala amene amazindikira kukhudzana ndi galasi. The mafuta silikoni ndi mbali ya zodzoladzola zambiri, penti ndi vanishi, magalimoto ndi mipando polishes. kuchuluka onse mndandanda mankhwala ndi zovuta.

Pambuyo mankhwala a pamalo osiyanasiyana polishes organosilicon woonda filimu aumbike pa iwo, ali kwambiri water- ndi fumbi katundu. Pambuyo kukhudzana pamwamba mosavuta kuchotsa litsiro.

Chimodzi mwa zinthu yotchuka kwambiri ya silikoni ndi silikoni mafuta PMS-200 (polymethylsiloxane). Izo ntchito monga nthumwi kumasulidwa, antifoaming wothandizira, lubricant zowonjezera ku mapulasitiki ndi surfactants. PMS-200 amagwiritsidwanso ntchito ngati insulator zipangizo zamagetsi, kwa kupanga zodzoladzola ndi zolinga zina. Mankhwala umodzi - osiyanasiyana yaikulu.

Kwambiri mwayeretsa mafuta silikoni komanso anthu akhala mantha-kungolandira madzimadzi zipangizo tcheru kuti kusintha molondola. mankhwala loyenera kumatha kudumpha ndi kugwirana manja, ngakhale zida umamumvera kugwedera. Zithandizanso kuchepetsa kugwedera flywheels mu osiyanasiyana injini.
