Kushandisa hydroxypropyl methylcellulose (HPMC) mukunamira mafomu kune akawanda mabhenefiti. HPMC ndeye semi-synthetic, isiri-ionic, yakakwira molecular huremu polymer iyo inowanzoshandiswa seyakakora, stabilizer, firimu rekare, uye retainer yemvura. Hunhu hwayo hwakasiyana hunoita kuti ishandiswe zvakanyanya mukunamira mafomu, kunyanya mukuvaka, kugadzira mapepa, kudhinda machira uye dhayi, zvizorwa, uye mushonga.
1. Yakanakisa kuchengetedza mvura kuita
Chinhu chakakosha cheHPMC ndechekuchengetedza kwayo mvura kwakanakisa. Mumvura-yakavakirwa zvinonamira, HPMC inokwanisa kuchengetedza hunyoro mune glue, nekudaro ichiwedzera nguva yekuvaka uye nekuona kuti inonamira haiome nekukurumidza mushure mekuputira. Izvi zvinonyanya kukosha kune zviitiko zvinoda maawa ekushanda kwenguva refu kana kuvakwa kwakapfava, sekunamira kwematairi, kupurasita zvinhu, etc. Kuchengeta mvura kunogonawo kuvandudza hukama pakati pe substrate neadhesive, uye kuderedza kutsemuka uye shrinkage yeadhesive layer inokodzera. kurasikirwa nemvura.
2. Kukora uye rheological properties kugadzirisa
HPMC inogona kuwedzera zvakanyanya viscosity yekunamatira, nekudaro ichiwedzera kunamatira kwayo uye kugadzikana. Inoshandura rheological properties yekunamatira, zvichiita kuti zvive nyore kushandisa panguva yekuvaka uye kuva nekupararira kwakanaka. Iko kukora mhedzisiro yeHPMC inobatsira kudzora kuyerera kwakamira kweanonamira uye kudzivirira kuyerera uye kudonha kweglue panguva yekuvaka. Inonyanya kukodzera kushandiswa panzvimbo dzakamira, dzakadai sekushongedza madziro uye tileing.
3. Firimu-kugadzira pfuma
HPMC inogona kugadzira firimu rakajeka mushure mekunge mvura yaputika. Iyi firimu-inogadzira pfuma inoita basa rakakosha mukunamira. Kune rumwe rutivi, iyo firimu yakaumbwa neHPMC inogona kuvandudza kusimba kwepamusoro uye kusimba kwekunamatira, kuderedza kuvhuvhuta kwemvura yepamusoro, uye nekudaro kunonoka kuoma kwekunamatira. Kune rumwe rutivi, iyo firimu inogonawo kupa imwe chiyero chedziviriro, kuderedza kukanganiswa kwekunze kwemamiriro ekunze pane yakanamatira layer, uye kunatsiridza kupikisa kwemamiriro ekunze uye kudzivirira hunyoro.
4. Kuvandudza kushanda kwekunamatira
Kuvapo kweHPMC kunonatsiridza zvakanyanya kuita kwekuvaka kwekunamatira. Semuenzaniso, inogona kuvandudza kutsvedza uye kushanda kwekunamira, zvichiita kuti kuvaka kuve nyore. Uye zvakare, HPMC inogona kuderedza mabhuru anogadzirwa neanonamira panguva yekuvaka, ichiita iyo yakapedzwa nzvimbo yakapfava uye yakapfava. Kunyanya mukuvaka kuvaka, kuderedza chizvarwa chebhururu kunobatsira kuvandudza aesthetics uye huwandu hwemhando yemadziro.
5. Kuvandudza kugadzikana kwezvinyorwa
Sekudzikamisa, HPMC inogona kudzivirira zvinonamira kubva pakudzika kana kugadzika panguva yekuchengetedza nekufambisa. HPMC mamorekuru anogona kuparadzirwa zvakaenzana mukunamira kuti aite yakagadzikana matatu-dimensional network chimiro, nekudaro ichivandudza kugadzikana kwenguva refu kweanonamatira. Iyi pfuma inonyanya kukosha mune zvakawanda zvinonamatira zvigadzirwa zvinoda kuchengetwa kana kutakurwa kwenguva yakareba.
6. Kuvandudza chisungo simba
Kunyangwe HPMC pachayo isiri yekunamira, inogona zvisina kunanga kunatsiridza simba rayo rechisungo nekuvandudza chimiro chemuviri cheanonamatira. Nekugadzirisa iyo rheology uye kuchengetwa kwemvura kwekunamatira, HPMC inogona kuve nechokwadi chekuti dhizaini yekunamatira yakanyatso kusungirirwa pamusoro peiyo substrate, nekudaro ichivandudza iyo yese yekubatanidza mhedzisiro yekunamatira. Uye zvakare, HPMC inogona zvakare kuwiriranisa nezvimwe zvinongedzo (senge emulsions, plasticizers, nezvimwewo) kuti iwedzere kusimudzira zvisungo zvinonamira.
7. Kuenderana uye kuchengetedzwa kwezvakatipoteredza
HPMC ndeye isiri-ionic cellulose kubva kune yakanaka makemikari inertness uye kuenderana kwakanaka neakasiyana-siyana emvura-based uye solvent-based adhesive system. Pamusoro pezvo, HPMC ndeyechisikigo uye inoora, iyo inosangana nezvinodiwa zvemazuva ano kuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba. Kuenzaniswa nemamwe masimbi ekugadzira, HPMC haiburitse zvinhu zvinokuvadza panguva yekuora, saka ine hushamwari kwezvakatipoteredza uye inokodzera maapplication ane yakakwirira yekuchengetedzwa kwezvakatipoteredza zvinodiwa, senge chikafu kurongedza, zvekurapa zvishandiso, nezvimwe.
8. Tembiricha uye asidhi uye alkali kuramba
HPMC ine kuchinjika kwakasimba kune shanduko yekushisa uye pH kukosha uye inogona kuchengetedza kuita kwayo kugadzikana mukati meimwe siyana. Izvi zvinoreva kuti HPMC inogona kuchengetedza kunaka kukora uye kuchengetedza kwemvura mhedzisiro kunyangwe pakupisa kwepamusoro kana mune isina kusimba asidhi kana isina simba alkaline nharaunda. Ichi chimiro chinochipa mukana mune mamwe akakosha ekushandisa nharaunda, senge anonamira maumbirwo anoshandiswa pasi petembiricha yakakwira kana akasimba ekuora kwemakemikari.
9. Anti-mildew kuita
HPMC ine mamwe anti-mildew uye antibacterial properties, izvo zvinoita kuti iwedzere kugadzikana kushandiswa mune dzimwe nzvimbo dzakakosha. Kune zvigadzirwa zvekunamira senge zvivakwa zvekuvaka izvo zvinoratidzwa kune hunyoro nharaunda kwenguva yakareba, anti-mildew zvivakwa zvinogona kuwedzera hupenyu hwesevhisi yechigadzirwa uye kuderedza kukukurwa kwema microorganisms pane inonamira layer.
Iko kushandiswa kweHPMC mune anonamira maumbirwo anogona kuvandudza zvakanyanya kuita kwese kwechigadzirwa. Haisi kungovandudza kuchengetedza kwemvura, kukora uye kugadzikana kwekunamatira, asiwo kunovandudza kushanda kwekuvaka uye kunowedzera simba rekubatanidza. Uye zvakare, kuchengetedza kwezvakatipoteredza kweHPMC, kuenderana kwemakemikari kwakakura, uye tembiricha uye asidhi uye alkali kuramba kunowedzera kuwedzera kushanda kwayo mune dzakasiyana siyana dzekushandisa. Nekuenderera mberi kwekufambira mberi kwetekinoroji, tarisiro yekushandiswa kweHPMC mumunda wekunamatira ichave yakakura.
