Isu tinoziva kuti hyaluronic acid, sechigadzirwa cherunako, ine moisturizing uye moisturizing mhedzisiro uye inoshandiswa zvakanyanya mumhando dzakasiyana dzekuchengetedza ganda zvigadzirwa senge kumeso mask, face cream uye moisturizers. Nekuvandudzwa kwesainzi uye tekinoroji uye kuvandudzwa kwemararamiro, kutsvaga kwevanhu zvipfeko hakusi kungonaka uye kudziya chete, asiwo kugadzikana, kushamwaridzana kwezvakatipoteredza uye hutano. Sechipfeko chinoshanda chine kukosha kwekuwedzera, inowedzera uye yakakurumbira. Kana hyaluronic acid ikasangana nemicheka, inoburitsa zvipi zvipfukuto?
Chii chinonzi hyaluronic acid uye chii chinoita?
Hyaluronic acid, inozivikanwawo se hyaluronic acid, ihombe yepolysaccharide inoumbwa nezvikamu zviviri zve disaccharide, D-glucuronic acid uye N-acetylglucosamine. Hyaluronic acid chinhu chakakosha chekubatanidza tishu senge munhu intercellular substance, vitreous body, joint synovial fluid, uye inoita basa rinokosha remuviri mukuchengetedza mvura, kuchengetedza nzvimbo yeextracellular, kudzora osmotic pressure, lubricating, nekusimudzira kugadzirisa masero.
Chii chinonzi hyaluronic acid textiles? Ndezvipi zvinobatsira?
Hyaluronic acid textiles inoreva machira ane hyaluronic acid nekubatanidza hyaluronic acid mamorekuru kune fiber kuburikidza nekupedza-kupedza maitiro. Kuenzaniswa nezvizoro, nguva yekubatana pakati pemachira nemuviri wemunhu yakareba uye nzvimbo yekubata yakakura. Hyaluronic acid, chikamu chinoshanda chakawedzerwa mumucheka, chinogona kuwana hutano hwehutano hweganda kusvika pamwero mukuru. Naizvozvo, hyaluronic acid machira anofarirwa nevatengi. Hyaluronic acid molecule ine nhamba huru yemapoka ehydroxyl uye mamwe mapoka epolar, ayo anogona kuumba inoenderera-dimensional mizinga yehuchi network payakadzika, zvichiita kuti Hyaluronic acid, se "molecular sponge", inogona kutora uye kuchengetedza 1000 nguva yayo. uremu hwemvura, nokudaro kuita kuti jira rive nyoro uye rakasununguka, uye kuchengetedza ganda rakanyorova uye risina kuoma. Hyaluronic acid inozivikanwa pasi rese seyakanakisa humectant, ine zita rekurumbidza re "natural moisturizing factor", uye zvakare iri glycosaminoglycan, isina hunhu hwemhando, kugarisana kwakanaka, uye haizokonzeredze kusawirirana uye matambudziko ekuchengetedza.
Ko hyaluronic acid machira anogadzirwa uye anogadziriswa sei?
Parizvino, pane nzira ina huru dzekugadzirira machira ane hyaluronic acid: dip rolling method, microcapsule method, coating method uye fiber method. Dipping nzira imhando yekugadzira nzira inoshandisa iyo yekupedzisa mumiriri ine hyaluronic acid kurapa jira nenzira yekunyudza. Iyi nzira iri nyore, yakanakira uye inoshanda, uye inoshandiswa zvakanyanya parizvino. Microcapsule nzira inzira inoshandisa firimu-kugadzira zvinhu kuputira hyaluronic acid mu microcapsules, uye wozogadzirisa microcapsules pamucheka fibers. Iyi nzira inokwanisa kuwana machira ane hunogara hunyoro kuchengetedza. Nzira yekuputira inowanzoisa hyaluronic acid pafiber pamusoro kuburikidza ne electrostatic self-assembly tekinoroji, iyo yakanyanya kuoma uye kushomeka kushandiswa. Iyo faibha nzira inzira yekuwedzera hyaluronic acid mu spinning stock solution uyezve kutenderera. Iyi nzira inogona kuwana machira e hyaluronic acid ane kusimba kwepamusoro, uye zvakare kutungamira kwehukuru-hukuru hwekugadzirisa hyaluronic acid machira mune ramangwana.
Nzira yekuziva sei kana pane hyaluronic acid mumachira?
Kazhinji, machira ane hyaluronic acid haagone kusiyaniswa nekutarisa kwekuona, uye zvakare zvakaoma kusiyanisa nemaoko maitiro ekunzwa. Naizvozvo, zvinodikanwa kuongorora kana machira ane zvakasikwa moisturizing factor hyaluronic acid nerubatsiro rwezviridzwa zvine hunyanzvi. Parizvino, pane nzira nhatu huru dzekuona zvirimo muhyaluronic acid: colorimetry, vhoriyamu kusabatanidzwa yakakwirira performance liquid chromatography uye high performance liquid chromatography. Iyo colorimetric nzira ine humbowo husina kunaka uye iri nyore kukanganiswa, izvo zvinogona kutungamirira kune zvisiri izvo bvunzo mhinduro uye nhema mhedzisiro. Iyo vhoriyamu yekusabvisa yakakwira performance liquid chromatography kazhinji ine yakakwira yekuona muganho, iyo inoshanda kune zvizorwa zvine yakakwira yehyaluronic acid, asi kwete kumachira ane zvishoma zvemukati. High performance liquid chromatography parizvino yakakamurwa kuita acidolysis - precolumn derivatization-yakakwirira performance liquid chromatography uye enzymolysis - high performance liquid chromatography. Pakati pavo, acidolysis - precolumn derivatization-test oparesheni nhanho dzinorema, uye kuberekazve kwebvunzo mhinduro kunoda kuvandudzwa, saka iyi nzira haishandiswe zvishoma; Nekuda kwekunaka kweiyo enzyme uye imwe chete enzymolysis chigadzirwa, iyo enzymolysis ine yakasimba chaiyo uye yakanyanya kurongeka, uye yakashandiswa zvishoma nezvishoma pakuongororwa kweiyo hyaluronic acid zvirimo mumasampuli akaomarara.
