Hydroxyprupyl methylcellose (HPMC)inhengo-yakadzvanywa yemvura inotorwa kubva ku cellulose, yakasikwa biopolymer.KunetsekaHPMC inoshandiswa zvakanyanya mune yekuvaka indasitiri, kunyanya mudhiri uye plaster mafomu. Basa rayo rekutanga mukuvandudza mari yekuchengetwa kwemvura yevhu, izvo zvakakosha kuti uwane kuita kwakakwana panguva yese yekusanganisa uye yekushandisa maitiro.
Basa rekuchengetwa kwemvura mumutumbi
Kuchengetwa kwemvura muMoter kunoreva kugona kwemusanganiswa kuti uchengete mvura mushure mekunge yaiswa kune nzvimbo, ichibvumira kuti irambe yakashanda uye iri hydrate panguva yekuisa uye kuporesa maitiro. Kugadziridza kwemvura kwakakodzera kunoita kuti durari inogona kuumba chisungo chakasimba neye substrate uye chinodzivirira nyaya dzakadai sekupaza, shringerge, kana kushamwaridzana. Kuchengetwa kwemvura kwakakwana kunogona kuguma nekuporesa kusingaenzaniswi, zvichitungamira kune asina kusimba majoini, akaderedza simba rekubatanidza, kana kuomesa musoro.
Kuchengetwa kwemvura kunonyanya kukosha kune yakaoma-kusanganisa mongwe, iyo yakatanga kubhadharwa kusvibiswa kwesimendi, jecha, uye vanowedzera. Kana ikasanganiswa nemvura panzvimbo yebasa, aya motsi anofanira kuchengeta huwandu hwakakwana hwekunyorova kuti uve nechokwadi che hydration yakakwana yeiyo simende, nekudaro kuwana simba rizere uye kusimba kwakazara. Mundima iyi, HPMC inoita basa rakakosha mukudzora kuchengetwa kwemvura uye nekuvandudza basa rekushanda uye kuita kwevhu.
Hovmc inowedzera sei kuchengetwa kwemvura
Mvura-solubility uye gel kuumbwa. Iyi gel chimiro inogona kusimbisa mamorekuru emvura uye kuderedza kubuda, nekudaro uchiwedzera kuchengetedza kwemvura yekuchengetwa kwemvura. Iyo gel inodzivirira dhudzi kubva pakuomesa kunze kwekukurumidza, uchichengetedza iyo nhanho yakakodzera yemunyoro panguva yekuporesa.
Viscosity Kudzora. Nekuwedzera iyo visikoka, HPMC inovimbisa kuti mvura yacho yakagoverwa zvakanyanya mumusanganiswa murefu uye inobatsira kudzivirira kusarudzika kwemvura uye zvimedu zvakasimbiswa. Uku kudzorwa kwekutongwa kusingavandisiravira kuchengetwa kwemvura muchivande asi kunowedzera basa rayo, zvichiita kuti zvive nyore kushandisa nekupararira.
Kudzivirira kwekutanga kuomesa: Munguva yekushandiswa kwemutumbi, kuomarara kwepamberi kunogona kuitika nekuda kwekukurumidza kurasikirwa kwemvura. HPMC inobatsira kudzora maitiro aya nekuita seyemvura-yekuchengetedza mumiririri. Izvi zvinovimbisa kuti duri rinoramba ririmo kwenguva yakareba, kubvumira kushamwaridzana kuri nani kune nzvimbo uye kudzivirira marara izvo zvinogona kuumba hydration isina kufanana.
Yakavandudzwa Adhisheni. Izvi zvakavandudzwa hydration zvinoguma neusungo wakasimba pakati pehudyu uye substrate, kuvandudza kudenha uye kuita kwese kuita. Izvo zvinonyanya kubatsira kana uchishanda nemidziyo yemufuta, yakadai sezvidhina kana kongiri, iyo inowanzo nyauka nekukurumidza.
Zvakanakira HPMC muMoter

| Yakawedzera nguva yakavhurika | Mota ine HPMC inoramba ichishanda kwenguva yakareba, ichibvumira nguva yakawanda yekugadziriswa uye kururamisa panguva yekushandisa. |
| Kugadziridzwa kwekuita mumamiriro ekunze akaoma | Munzvimbo dzine nzvimbo dzakakwirira dzekubereka dzimba, kugona kweHPMC kuchengetedza mvura inovimbisa kuti duri rinoramba riripo rinoshanda uye harina kuoma zvachose. |
Zvikumbiro zveHPMC muMoter
HPMC inowanzoshandiswa mumhando dzakasiyana-siyana dzevhudzi, kusanganisira:
Tile anomirira.
Mutete-murefu motsi.
Gadzirisa motsa.
Plaster uye stucco.
Yakaoma-musanganiswa motsi.
Zvinhu zvinokanganisa kushanda kweHPMC muMoter
Nepo HPMC inopa zvakaringana, kushanda kwayo mukuvandudza kuchengetedzwa kwemvura kunogona kukurudzirwa nezvikamu zvinoverengeka:
Kusvinura kweHPMC: Huwandu hweKunetsekaHPMC inoshandiswa mumusanganiswa wedhaka zvakananga zvinokanganisa zvakananga zvemvura yayo yekuchengetwa kwemvura. Kunyanya HPMC inogona kusapa mari yakakwana yekuchengetwa, nepo huwandu hwakawanda hwaigona kukanganisa hutongi hwehudyu uye kushanda.
Type uye giredhi reHPMC. Kusarudza mhando yakakodzera yeHPMC yeiyo chaiyo application inokosha yekuzadzisa iyo inodiwa mvura yekuchengetwa uye kuita kwemota.
Mamiriro ekunze: Mother inosanganisa neHPMC inogona kuzvibata zvakasiyana mumamiriro akasiyana emamiriro ekunze. Tembiricha yakakwirira kana kuti yakanyorova inowedzera inogona kuwedzera huwandu hwekubereka, zvinogona kuderedza kushanda kweHPMC mukuchengetwa kwemvura. Mumamiriro ezvinhu akadaro, matanho ekuwedzera anogona kunge ari madikanwa kuti ave nechokwadi chekuti hydration chaiyo.
Kuwirirana nevamwe vanowedzera. Kubatanidzwa pakati peHPMC uye zvimwe zvinongedzo zvinofanirwa kufungwa nekuona kuti vanoshanda kuti vashande synergistically kusimudzira kuita kwemutya.
Hpcinhaka yakaoma mune motoro maumbirwo, kunyanya nekuda kwekugona kwayo kuvandudza kuchengetwa kwemvura. Nekuumba chimiro cheGel chinobatsira mamorekuru vemanyorero, HPMC inobatsira kudzivirira nguva yekuomesa, inokwidziridza kushanda kwemusanganiswa, uye inovimbisa hydration iri nani yeiyo simenti. Izvi zvivakwa zvinopa kuvandudza kudedera, kuderedza shrinkage, uye kuvandudza kusimba kwerudzi. Kushandiswa kwe KunetsekaHPMC inonyanya kubatsira munzvimbo dzine nharaunda dzakakwirira dzekubuda kana kuti zvikumbiro zvinoda yakawedzerwa nguva yakavhurika. Kunzwisisa zvinhu zvinokonzeresa kuita kweHPMC uye kusarudza iyo chaiyo yekukasira uye mhando yechero imwe neimwe application yakakosha kune inokonzeresa kuita kwemota.
