Kodi Mafuta a Methyl Silicone Ndi Chiyani?
Kawirikawiri, methylmafuta a siliconendi madzi opanda mtundu, osakoma, opanda poizoni komanso osavunda.Sisungunuka m'madzi, methanol kapena ethylene glycol.Itha kusungunuka ndi benzene, dimethyl ether, carbon tetrachloride kapena palafini.Amasungunuka pang'ono mu acetone, dioxan, ethanol ndi butanol.Koma mafuta silikoni methyl, chifukwa mphamvu intermolecular ndi yaing'ono, unyolo maselo ndi ozungulira, ndipo magulu organic akhoza zimayenda momasuka, ali ndi makhalidwe abwino kufalitsa ntchito, lubricity, mkulu ndi otsika kutentha kukana, kukana nyengo, kukana ma radiation, High flash point, low surface tension and physiological inertia, etc. Amagwiritsidwa ntchito kwambiri m'mafakitale a tsiku ndi tsiku.mankhwala, makina, magetsi,nsalu, zokutira, mankhwala ndi chakudya, etc.
Tiye Makhalidwe aMafuta a Methyl Silicone
Mafuta a silicone a methyl ali ndi magwiridwe antchito apadera.
■ Kukana kutentha kwabwino
Mu molekyulu yamafuta a silicone, unyolo waukulu umapangidwa ndi -Si-O-Si-, womwe uli ndi mawonekedwe ofanana ndi ma polima opangidwa ndi inorganic ndipo uli ndi mphamvu zambiri zomangira.Chifukwa chake imakhala ndi ntchito yabwino kwambiri yolimbana ndi kutentha.
■ Kukana bwino kwa okosijeni ndi kukana nyengo
■ Kuchita bwino kwa insulating yamagetsi
Mafuta a silicone ali ndi mphamvu zabwino kwambiri za dielectric.Ndi kusintha kwa kutentha ndi nambala yozungulira, mawonekedwe ake amagetsi amasintha pang'ono.Dielectric nthawi zonse imachepa pamene kutentha kumawonjezeka, koma kusintha kumakhala kochepa kwambiri.Mphamvu yamafuta a silikoni ndi yotsika ndipo imawonjezeka ndi kutentha kumakwera, koma palibe malamulo afupipafupi.Voliyumu resistivity amachepetsa ndi kuwonjezeka kutentha.
■ Hydrophobicity yabwino kwambiri
Ngakhale unyolo waukulu wa silikoni mafuta wapangidwa ndi polar chomangira, Si-O, non-polar alkyl magulu pa unyolo mbali amayang'ana panja kuteteza mamolekyu madzi kulowa mkati ndi kuchita hydrophobic udindo.Kukangana kwapakati pakati pa mafuta a silicone ndi madzi ndi pafupifupi 42 dynes / cm.Ikafalikira pagalasi, chifukwa cha kuthamangitsa madzi, mafuta a silikoni amatha kupanga ngodya yolumikizana pafupifupi 103 °, yofanana ndi sera ya parafini.
■ Small mamasukidwe akayendedwe-kutentha koyenera
Kukhuthala kwa mafuta a silicone ndi otsika ndipo amasintha pang'ono ndi kutentha.Zimakhudzana ndi mawonekedwe ozungulira a mamolekyu amafuta a silicone.Mafuta a silicone ndi omwe ali ndi mawonekedwe abwino kwambiri a viscosity-kutentha pakati pa mitundu yonse yamafuta amadzimadzi.Chikhalidwe ichi chimamveka bwino pazida zotayira.
■ High kukana kukanika
Chifukwa cha mawonekedwe ake ozungulira komanso mtunda waukulu wa intermolecular, mafuta a silicone ali ndi kukana kwambiri.Pogwiritsa ntchito mawonekedwe a mafuta a silicone, amatha kugwiritsidwa ntchito ngati kasupe wamadzimadzi.Poyerekeza ndi makina masika, voliyumu akhoza kuchepetsedwa kwambiri.
■ Kuthamanga kwapansi pamtunda
Kutsika kwapansi pamtunda ndi khalidwe la mafuta a silicone.Kutsika kwapansi kumasonyeza ntchito yapamwamba.Chifukwa chake, mafuta a silicone ali ndi magwiridwe antchito abwino kwambiri ochotsera thovu ndi antifoaming, kudzipatula ndi zinthu zina komanso ntchito yopaka mafuta.
■ Non-toxic, non-volative and physiological inertia
Kuchokera pamalingaliro achilengedwe, siloxane polima ndi imodzi mwazinthu zomwe zimagwira ntchito kwambiri.Dimethyl silikoni mafuta ndi inert kwa zamoyo ndipo alibe zochita kukanidwa ndi nyama.Chifukwa chake chagwiritsidwa ntchito kwambiri mu dipatimenti ya opaleshoni ndi dipatimenti yamankhwala yamkati, mankhwala, chakudya ndi zodzoladzola, etc.
■ Mafuta abwino
Mafuta a silicone ali ndi zinthu zambiri zabwino kwambiri monga mafuta opangira mafuta, monga malo okwera kwambiri, malo otsika ozizira, kutentha kwa kutentha, kusintha kwa viscosity pang'ono ndi kutentha, kulibe chitsulo komanso kusokoneza mphira, pulasitiki, utoto ndi filimu ya utoto wa organic, kutsika pamwamba. mavuto, zosavuta kufalitsa pa zitsulo pamwamba ndi zina zotero.Pofuna kukonza zitsulo kuti zikhale zokometsera zazitsulo za silikoni, zowonjezera zowonjezera zomwe zingathe kusakanikirana ndi mafuta a silicone zikhoza kuwonjezeredwa.Mafuta opaka mafuta a silicone amatha kusintha kwambiri poyambitsa gulu la chlorophenyl mu unyolo wa siloxan kapena m'malo mwa gulu la dimethyl ndi gulu la trifluoropropyl methyl.
