Silicone roj yog cov khoom muaj nyob hauv cov tshuaj pleev ib ce thiab cov khoom lag luam. Ntau tus neeg yuav xav tias lawv zoo ib yam, thiab qee tus txawm siv cov roj silicone hauv kev kho tawv nqaij thiab kev tu plaub hau, ua rau muaj kev phom sij rau kev noj qab haus huv. Qhov tseeb, txawm hais tias muaj cov qauv tshuaj zoo sib xws, lawv sib txawv hauv kev purity, kev nyab xeeb, thiab daim ntawv thov, zoo li qhov sib txawv ntawm "lub rooj ntsev" thiab "kev lag luam ntsev."
Ib. Lub hauv paus chiv keeb: Silicone Roj yog dab tsi?
Silicone roj, tshuaj hu ua polysiloxane, yog ib chav kawm ntawm polymers nrog silicon -oxygen (Si-O) bonds raws li cov saw tseem ceeb thiab cov organic pawg (xws li methyl pawg) txuas rau sab chains. Cov qauv tshwj xeeb no ua rau nws muaj ntau yam zoo heev physicochemical zog:
Tsis tshua muaj qhov nro: Ib qho yooj yim rau kev sib kis, ua rau muaj kev sib tw, velvety zoo rau ntawm daim tawv nqaij.
Chemically inert: ruaj khov thiab tsis nkag siab nrog lwm yam tshuaj.
Qhov kub thiab txias tsis kam: tseem nyob ruaj khov tshaj qhov kub ntau yam.
Hydrophobicity: Kev ua tau zoo ntawm cov dej tsis zoo.
Kev ua pa siab: Tsis cuam tshuam rau daim tawv nqaij ua pa tom qab tsim cov yeeb yaj kiab.
Cov kev sib txawv no tau ua rau cov roj silicone kom pom cov ntawv thov hauv ntau qhov chaw, los ntawm cov tshuaj niaj hnub mus rau kev lag luam. Txawm li cas los xij, nws yog qhov tseeb los ntawm qhov kev sib koom kawg no uas cov roj pleev xim silicone thiab cov roj silicone roj sib txawv, mus rau hauv ob qho kev qhia sib txawv.
Ob. Txoj kev sib txawv: Hauv -Kev sib piv qhov tob ntawm qhov sib txawv
1. Qhov txawv ntawm qhov: Purity and Safety Standards
Qhov no yog qhov tseem ceeb tshaj plaws thiab tsis muaj qhov sib txawv ntawm ob.
Cosmetic Silicone Roj - "Kev zoo nkauj ntawm purity"
Qib: Yuav tsum ua kom tau raws li cov qauv tshuaj pleev ib ce lossis tshuaj.
Purity: Ua kom muaj kev purity siab heev los ntawm ntau yam kev sib cais, kev ua kom huv, thiab cov txheej txheem pom.
Kev Tswj Xyuas Kev Nyab Xeeb:
Hnyav Hlau txwv: nruj me ntsis tswj cov ntsiab lus ntawm cov hlau hnyav xws li txhuas, arsenic, thiab mercury, ua raws li cov txheej txheem kev nyab xeeb kev nyab xeeb ntawm ntau lub teb chaws.
Kev tshem tawm impurity: Tshwj xeeb tshem tawm lossis nruj me ntsis tswj qis -molecular- hnyav cyclic siloxanes (tshwj xeeb yog D4, D5, thiab D6) los ntawm cov txheej txheem tshwj xeeb. D4 tau raug txheeb xyuas tias yog tshuaj tua kab mob los ntawm EU thiab nruj me ntsis txwv hauv cov tshuaj pleev ib ce.
Kev Ntsuam Xyuas Kab Mob: Yuav tsum dhau tag nrho cov kev ntsuas kev nyab xeeb, suav nrog cov tawv nqaij khaus, khaus qhov muag, ua xua, thiab kuaj tshuaj toxicology.
Muaj Silicone Roj - "Kev Ua Haujlwm Ua Ntej"
Qib: Qib Industrial nkaus xwb.
Purity: Tsawg purity yuav tsum tau; Lub hom phiaj tseem ceeb ntawm lub cev (piv txwv li, viscosity, flash point).
Residual Impurities: Feem ntau muaj cov catalyst residues, incompletely reacted intermediates, thiab siab concentrations ntawm qis-molecular- hnyav cyclic siloxanes. Cov impurities no muaj feem cuam tshuam rau ntawm daim tawv nqaij thiab cov mucous daim nyias nyias thiab tej zaum yuav nyob rau hauv ib puag ncig.
Tsis Muaj Kev Nyab Xeeb Kev Nyab Xeeb: Tsis muaj kev ntsuam xyuas tib neeg kev nyab xeeb lossis kev ntsuam xyuas.
2. Qhov txawv ntawm Lub Hom Phiaj: Cov cheeb tsam thov
Cov qauv sib txawv ncaj qha txiav txim siab lawv qhov sib txawv ntawm daim ntawv thov scenarios.
Cosmetic Silicone Oils: Dedicated los txhim kho daim tawv nqaij xav thiab pleev nyhuv.
Cov khoom siv tawv nqaij: Hauv cov tshuaj pleev, tshuaj pleev, thiab tshuaj pleev thaiv hnub, muab qhov ua kom zoo dua qub, tsis yog -greasy moisturizing xav thiab txo cov nplaum.
Cov Khoom Siv Kho Cov Plaub Hau: Hauv cov tshuaj zawv plaub hau, tshuaj kho mob, thiab lub ntsej muag plaub hau, kho cov plaub hau cuticles thiab muab cov plaub hau smoothness, ci, thiab tiv thaiv - muaj peev xwm tangling.
Cov khoom pleev xim: Hauv cov hauv paus thiab primers, muab kev sib kis zoo thiab ua tiav ntev - cov teebmeem pleev xim ntev.
Industrial Silicone Roj: Pab kev lag luam thiab kev tsim khoom.
Lubrication: Raws li qhov siab -kub, dav-kub- ntau yam tshuab lubricant.
Defoaming: Raws li cov defoamer zoo heev hauv roj av, papermaking, thiab dej khib nyiab.
Pwm Tso Tawm: Siv rau pwm tso tawm hauv cov yas, roj hmab, thiab hlau casting.
Waterproofing: Siv rau waterproofing hauv kev tsim kho thiab textiles.
3. Qhov txawv ntawm qhov sib txawv: qhov tshwm sim thiab daim ntawv
Txawm nyob rau hauv tsos, ua tib zoo soj ntsuam yuav qhia tau qhov sib txawv.
Tshuaj pleev ib ce silicone roj: Feem ntau tsis muaj xim, tsis muaj ntxhiab, thiab pob tshab oily kua, nws zoo nkaus li huv thiab ntshiab.
Cov roj silicone muaj roj: Tej zaum yuav muaj cov xim daj me ntsis vim yog impurities thiab tej zaum yuav muaj cov tshuaj tsw qab tshwj xeeb.
Peb. Lub tswv yim yuam kev uas yuav tsum tau qhia meej thiab ceeb toom hnyav: Cov roj silicone yuav tsum tsis txhob siv rau tib neeg lub cev!
Qhov li-hu ua "kev tu tawv nqaij thiab plaub hau" kev kho mob hauv online siv cov roj silicone muaj kev phom sij heev thiab tsis muaj lub luag haujlwm. Qhov kev coj ua no sib npaug rau kev sib cuag ncaj qha rau cov khoom siv raw khoom uas tsis paub txog cov hlau hnyav, acidic impurities, thiab irritating compounds nrog daim tawv nqaij thiab cov hauv paus hniav, uas yuav ua rau:
Kev mob hnyav: tawv nqaij ua xua, liab thiab o, folliculitis, mob qhov muag hnyav.
Kev pheej hmoo mob ntev: Cov tshuaj phem tau nqus los ntawm daim tawv nqaij thiab sib sau ua ke hauv lub cev, ua rau ntev - kev puas tsuaj rau kev noj qab haus huv.
Plaub. Kev lag luam Outlook thiab Summary
Raws li cov neeg siv khoom tau nce qhov tseem ceeb ntawm kev nyab xeeb, kev ua tau zoo, thiab cov neeg siv kev paub dhau los, cov roj silicone kom zoo nkauj tau hloov mus tas li. Kev lag luam tab tom hloov mus rau kev tsim cov roj silicone tshiab uas yog ib puag ncig zoo, ntau biodegradable (xws li alkyl- hloov cov roj silicone), thiab ua haujlwm tshwj xeeb.
Hauv cov ntsiab lus, thaum cov tshuaj pleev ib ce thiab kev lag luam silicone roj los ntawm tib qhov chaw, lawv tau sib txawv heev vim qhov tseem ceeb ntawm "purity" thiab "kev nyab xeeb." Lub qub yog ib qho pov thawj thiab txhim khu kev qha kev zoo nkauj, thaum lub tom kawg yog ib qho khoom siv siab -kev ua haujlwm. Rau cov kws tshaj lij kev lag luam, kev ua raws li kev ua raws cai thiab kev nyab xeeb ntawm cov khoom siv raw yog lub luag haujlwm tsis lees paub; rau cov neeg siv khoom, paub txog qhov sib txawv yog qhov tseem ceeb rau kev ua kom lawv txoj kev noj qab haus huv thiab koom nrog kev tshawb fawb thiab kev xav txog kev tu tawv nqaij thiab kev tu plaub hau.
