Cov Yam Cuam Tshuam Rau Kev Ua Haujlwm ntawm UV Filters

Cov yam ntxwv ua tau zoo ntawm titanium dioxide thiab zinc oxide sib txawv ntau nyob ntawm cov khoom ntawm qib tshwj xeeb siv, piv txwv li txheej, daim ntawv lub cev (hmoov, roj-raws li dispersion, dej-raws li dispersion).Cov neeg siv yuav tsum sab laj nrog cov neeg muag khoom ua ntej xaiv qib tsim nyog tshaj plaws los ua kom tau raws li lawv cov hom phiaj kev ua tau zoo hauv lawv cov txheej txheem tsim cov tshuaj.

Qhov ua tau zoo ntawm cov lim dej organic UV uas yaj tau hauv roj yog cuam tshuam los ntawm lawv qhov kev yaj hauv cov tshuaj emollients siv hauv cov mis. Feem ntau, cov tshuaj polar emollients yog cov kuab tshuaj zoo tshaj plaws rau cov lim dej organic.

Qhov ua tau zoo ntawm txhua lub lim dej UV yog cuam tshuam los ntawm tus cwj pwm rheological ntawm cov mis thiab nws lub peev xwm los tsim ib daim zaj duab xis sib npaug, sib xws ntawm daim tawv nqaij. Kev siv cov zaj duab xis-formers thiab rheological additives feem ntau pab txhim kho qhov ua tau zoo ntawm cov lim dej.
Kev Sib Xyaws Ua Ke ntawm Cov Lim UV (kev sib koom ua ke)

Muaj ntau yam kev sib xyaw ua ke ntawm cov lim dej UV uas qhia txog kev sib koom ua ke. Cov txiaj ntsig zoo tshaj plaws feem ntau yog ua tiav los ntawm kev sib xyaw ua ke cov lim dej uas sib pab ua ke, piv txwv li:-
• Kev sib xyaw cov lim dej uas yaj tau roj (lossis cov roj uas tawg ua tej daim me me) nrog cov lim dej uas yaj tau dej (lossis cov dej uas tawg ua tej daim me me)
• Ua ke cov lim UVA nrog cov lim UVB
• Kev sib xyaw cov lim dej inorganic nrog cov lim dej organic

Kuj tseem muaj qee qhov kev sib xyaw ua ke uas tuaj yeem ua rau muaj lwm cov txiaj ntsig, piv txwv li nws paub zoo tias octocrylene pab ua kom cov duab ruaj khov qee cov ntxaij lim dej uas tsis yooj yim pom xws li butyl methoxydibenzoylmethane.

Txawm li cas los xij, ib tug yuav tsum nco ntsoov txog cov cuab yeej cuab tam ntawm kev txawj ntse hauv thaj chaw no. Muaj ntau daim ntawv pov thawj uas npog cov kev sib xyaw ua ke ntawm cov lim dej UV thiab cov neeg tsim cov qauv raug qhia kom ib txwm xyuas kom meej tias qhov kev sib xyaw ua ke uas lawv npaj siab siv tsis ua txhaum cov ntawv pov thawj thib peb.

Xaiv lub lim dej UV zoo rau koj cov tshuaj pleev ib ce

Cov kauj ruam hauv qab no yuav pab koj xaiv cov lim dej UV zoo rau koj cov tshuaj pleev ib ce:
1. Teem cov hom phiaj meej rau kev ua tau zoo, cov yam ntxwv zoo nkauj thiab cov lus thov rau cov qauv.
2. Xyuas seb cov lim dej twg raug tso cai rau lub khw uas xav tau.
3. Yog tias koj muaj lub chassis tshwj xeeb uas koj xav siv, xav txog seb cov lim dej twg yuav haum nrog lub chassis ntawd. Txawm li cas los xij, yog tias ua tau nws yog qhov zoo tshaj plaws los xaiv cov lim dej ua ntej thiab tsim cov qauv nyob ib puag ncig lawv. Qhov no muaj tseeb tshwj xeeb nrog cov lim dej inorganic lossis particulate organic.
4. Siv cov lus qhia los ntawm cov neeg muag khoom thiab/lossis cov cuab yeej kwv yees xws li BASF Sunscreen Simulator los txheeb xyuas cov kev sib xyaw ua ke uas yuav tsumua tiav qhov SPF uas xav tauthiab UVA lub hom phiaj.

Cov kev sib xyaw ua ke no ces tuaj yeem sim ua cov qauv. Cov txheej txheem kuaj SPF thiab UVA hauv vitro muaj txiaj ntsig zoo rau theem no los qhia tias cov kev sib xyaw ua ke twg muab cov txiaj ntsig zoo tshaj plaws hauv kev ua tau zoo - cov ntaub ntawv ntxiv txog kev siv, kev txhais lus thiab kev txwv ntawm cov kev xeem no tuaj yeem sau nrog SpecialChem e-kev cob qhia chav kawm:UVA/SPF: Kev Txhim Kho Koj Cov Txheej Txheem Kev Ntsuas

Cov txiaj ntsig ntawm kev xeem, nrog rau cov txiaj ntsig ntawm lwm yam kev xeem thiab kev ntsuam xyuas (piv txwv li kev ruaj khov, kev ua haujlwm ntawm cov tshuaj tiv thaiv, kev xav ntawm daim tawv nqaij), ua rau tus neeg tsim cov tshuaj xaiv tau qhov kev xaiv zoo tshaj plaws thiab coj kev txhim kho ntxiv ntawm cov tshuaj.
