Daim ntawv thov ntawm polydimethylsiloxane hauv lub neej
cosmetic
Polydimethylsiloxane muaj lubric lubrication zoo thiab muaj peev xwm tsim tau ib cov xim tsis muaj kev tiv thaiv waterproofing tom qab siv daim tawv nqaij, tab sis nws tsis muaj nplaum thiab greasy siab thiab muaj zoo gloss.
Zoo anti-ultraviolet radiation: nws tsis oxidize thiab deteriorate hauv ultraviolet teeb, ua rau ntawm daim tawv nqaij voos.
Kev ua zoo antistatic: Qhov kev ntsuam xyuas pom tau hais tias hluav taws xob ntawm daim tawv nqaij uas muaj cov tawv nqaij uas muaj silicone nplaum yog tshem tawm, thiab cov av zoo tsis zoo.
Cov kab mob roj zoo: Txawm hais tias muaj yeeb yaj kiab los ntawm daim tawv nqaij, nws tsis zoo rau cov hws tawm.
Nws muaj qeeb tso thiab aroma-kho cov nyhuv ntawm qhov tsw thiab ntxhiab tsw, yog li cov ntxhiab ntev sij hawm ntev ntev thiab ruaj khov, sib cav sib luag, thiab tsis muaj kev phom sij rau lwm yam khoom ntawm lub cosmetic, tshwj xeeb tshaj yog cov khoom sib txuam.
Nws yog non-toxic, odorless, tasteless, tsis ua tsiv thiab ua xua rau ntawm daim tawv nqaij, muaj kev nyab xeeb siab, thiab muaj tej yam teeb meem curative rau ntawm tej tawv nqaij, xws li sweaty neuropathic dermatitis thiab cov hauj lwm dermatitis.
Cov khoom hluav taws xob
Polydimethylsiloxane, uas yuav siv tau rau hauv cov khoom sib txuas rau hluav taws xob thiab hluav taws xob.
Tawv khoom
Polydimethylsiloxane yuav siv tau rau fiber ntau, tawv: tshuaj pleev dej, softener, tes xav zoo, ntxias tau rau kev lag luam dyeing, lubrication ntawm kev xaws. Cov emulsion yuav siv rau lub fatliquoring ntawm tawv los txhim khu lub hydrophobicity, softness thiab comfort ntawm tawv. Nws tuaj yeem siv los kho cov tawv nqaij los txhawm rau txhawm rau ua haujlwm, dej tshuaj thiab kev pwm tawm.
Brightener
Polydimethylsiloxane, tsim rau siv los ua ib qho khoom ci zoo nkauj hauv tsheb, rooj tog zaum, khau khoom, cement khoom, thiab lwm yam, xws li automotive brighteners, cov tshuaj ntxuav cov rooj tog zaum, cov ntaub qhwv vov tsev, cov ntaub ntawv zoo tshaj plaws tuaj yeem ua tiav nrog tsawg tshaj ntawm kev siv.
Tso Tawm Tsam
Polydimethylsiloxane tuaj yeem raug siv los ua tus neeg sawv cev tso rau roj hmab lossis khoom yas (lub tais daim phiaj, lub hau hau, lub hau, thiab lwm yam) thiab EVA khau. Nws tuaj yeem siv ncaj qha los sis diluted nrog cov dej tsis tshua muaj zog rau 10-200 zaug. Ruaj thiab muaj ntau yam.
Roj nplua nyeem
Polydimethylsiloxane yuav siv los ua lub roj nplua rau cov roj hmab extruding khoom xws li cov khoom siv thauj khoom siv. Nws tuaj yeem siv ua lub roj nplaum rau cov qauv hauv qab no: piam, pauv cov xov ntxiv, kev tsim khoom thom khwm thiab ris tsho hauv qab, lubrication ntawm stitches, thiab iav fiber ntau mesh.
Lwm qhov chaw
Polydimethylsiloxane yog hom zaub mov-qib defoamer uas tuaj yeem siv rau hauv cov tshuaj tua kab mob thiab cov khoom noj, thiab nyob rau hauv qhov defoaming ntawm fermentation lub sijhawm. Vim hais tias nws tsis yog ib qho tshuaj lom thiab tsis ua rau lub cev tsis muaj zog, nws kuj yog siv los kho tus kab mob ntsig txog kev kho mob ntsig txog kev mob ntsws thiab kab ntsig. Cov khoom uas muaj lub npe hu ua siloxane (Silicones, los yog silicone oil) yog lub ntsiab lus tseem ceeb rau ib chav silicone oxidized polymers. Dimethicone tsuas yog ib qho ntawm cov neeg siv feem ntau. Ntxiv mus, muaj ethyl silicone roj, methyl phenyl silicone roj, waxy silicone roj thiab cov zoo li. Nyob rau hauv cov ntsiav tshuaj polishing tus neeg ua hauj lwm wax, ib tug me me ntawm cov khoom no feem ntau ntxiv rau txhim khu lub ci ci thiab noo noo ntawm ib sab ntawm ib sab. Nyob rau hauv ointment, cov khoom no yog qhov zoo tshaj plaws hydrophobic matrix vim nws zoo lubricity, daim ntawv thov yooj yim, uas tsis yog-khi ntawm cov khaub ncaws, thiab tsis muaj hindrance rau lub cev ua haujlwm ntawm daim tawv nqaij. Nws feem ntau siv nrog ib lub hnab ntim roj los ua ib qho tshuaj pleev tiv thaiv rau kev tiv thaiv kev ua kom lub cev muaj dej thiab cov dej kua qaub, acids, thiab lwm yam zoo li.
