Hpmc mumabhonzo anoshanda sei?

HPMC (hydroxyprEpropyl methylcellose) inguva yakakosha hafu-synthetic polymer zvinhu zvinoshandiswa zvakanyanya mumunda wekubatanidza. Iyo ndiyo mvura- uye organic solvent-solule cellows defivative inotora akasiyana siyana maviri makuru ezvakakosha muzvipfeko zvakakonzerwa nemakemikari akasarudzika uye emakemikari.

1. Firimu-kugadzira zvivakwa
Imwe yemabasa makuru eHPMC yakafanana nemumiriri wefirimu. Mushure mekunge yanyungudutswa mumvura kana organic solvent, inogona kuumba mhinduro yunifomu, uye mushure mekunge solvent kuputika, inoumba dense uye yunifomu firimu. Iyi firimu ine yakanaka michina simba uye kushanduka uku uchigovera dziviriro kune iyo substrate. Semuenzaniso, mumheni yezvinodhaka, HPMC inopa mabasa akadai sekunyorova kuramba uye kuzviparadzaniswa kwechiedza, ayo anowedzera kusimba kwezvinodhaka.

2. Adhisheni
Iyo yakakwira viscosity yeHPMC inogonesa kuita senge binder, ichibatsira kuunganidza zvinhu zvine chekuita nekujeka kumusoro. Mushure mekurapa, inogona kusimudzira simba rekubatanidza pakati pekuvhara uye substrate, kudzivirira kubatirira kubva pakubata kana kupaza.

3. Kukakavara uye kusimbisa mhedzisiro
HPMC ine kugona kwakanaka uye kunogona kuwedzera zvakanyanya zvikwangwani zvekuvhara masisitimu kunyangwe pakadzika pakatarisana. Hunhu uhwu hunogona kugadzirisa rheology yezvinyorwa zvekuvhara, zvichikupa zvakanaka thkXotropy uye mukushandiswa panguva yekuvaka. Uye zvakare, iyo inoshamisa mhedzisiro yeHPMC inodzivirira kugadziriswa kwemifananidzo kana mafirita muCoating, ichivimbisa kufanana kwekuumbwa.

4. Mvura uye moisturizing
Mapoka eHydrophobic (methyl uye hydroxypruppropyl) yeHPMC inopa zvimwe zvinhu-zvinodzokorora zvemvura uye zvinogona kupa imwe mwero wekudzikama kwemvura mumarara. Panguva imwecheteyo, HPMC inogona kuita zvinobudirira kudzora huwandu hwemvura, nekudaro nekuwedzera nguva yekuomesa yekuvhara nekuvandudza kudzvanywa kwekuvaka. Mukuwedzera, mune zvimwe zviitiko zvakakosha (zvakadai sekurova kwehmc), iyo moisturizing mhedzisiro yeHPMC inogona kubatsira kudzivisa kurasikirwa kwakanyanya kwemvura, nekudaro kugadzirisa simba rekubatanidza rechinyorwa.

5. Kumiswa uye kusimbisa maitiro
Muzviyo-zvakavakirwa mvura, HPMC zviito zvekumisikidza nekuwedzera kuwanda kweiyo iyo yemvura system, iyo inogona kudzivirira zvakanyatsoita zvimedu zvakasikwa (zvakadai semafashoni kana kuti mafirita) kubva mukunyura nekuda kwesimba. Yayo yakanaka yekuparadzira zvivakwa zvinoita kuti ruvara uye ruvara rwevakakomberedza yunifomu, ichivandudza iyo yakazara aesthetics uye mashandiro.

6. Rongedza nguva yekuoma
Iyo yakanyorova yekudzora zvivakwa zveHPMC inogonesa kufuratira nguva yekuomesa yejasi. Nekuderedza chiyero chekubuda kwemvura, zvinobatsira kudzora nguva yekuparadzira kwekusagadzikana kwepamusoro uye zvakazara kurapa kwekucheka, kudzivirira kupaza matambudziko kunokonzerwa nekumhanyisa kukurumidza kuomesa kumhanya.

7. Kubata Kwemamiriro ekunze uye Kudzivirirwa
Iyo yekubatanidza firimu yakaumbwa neHPMC ine imwe UV kuramba uye makemikari kuramba, izvo zvinogona kuchengetedza substrate kubva kune zvinokuvadza zvinhu mumamiriro ekunze. Semuenzaniso, mukudzivirira kwehuni dzehuni kana simbi, hpm inogona kusimudzira kusimba kwekuchera uye kuwedzera hupenyu hwaro hwebasa.

8. Kudzivirirwa kwezvakatipoteredza uye kuchengetedzwa
Semunhu asiri-ane chepfu uye zvakatipoteredza hushamwari zvinhu, HPMC inosangana nezvinodiwa zvakasvibirira zvejasi razvino yejasi. Mune akawanda emvura-yakavakirwa mvura, inogona kutsiva tsika organic sol sol sol sol sol talatipi compic makomputa (voc), uye kugadzirisa nzvimbo yekuvaka.

HPMC inoita basa rakasiyana uye rakaoma basa mumakonzo. Yayo firimu-yekuumba, inoshamisira, inoshamisira, inodzokorora mvura uye moisturizing zvivakwa zvinoita kuti ive isina kukosha mubatanidzwa mafambiro ekubatanidza. Nekutsiva mariri ayo anoshamisa, degree rekutsiva uye kuwedzera huwandu, izvo zvinodikanwa zvekubatanidza muminda dzakasiyana zvinogona kusangana, zvakadai zvekuvaka mishonga, zvekuvakira uye zvekuvakira midziyo uye maindasitiri. Naizvozvo, HPMC munhu anobatsira mukusimudzira kwehunyanzvi hwazvino hwekubatanidza tekinoroji.
