HydroxyPropyl methylcellose (HPMC) ishandara yemuviri yakashandiswa zvakanyanya mune zvekuvaka, kunyanya mumuchina wakaputika. Zvivakwa zvaro zvakasarudzika zvinosimudzira kuita uye kushanda kwemauto, zvichiita kuti zvive zvakakosha mumanyorero akasiyana siyana.
Chemical Properties uye Inoshanda Zvakanakira HPMC
HPMC ndeye isiri-ionic cellulose ether inotorwa kubva kune yakasikwa celloulose kuburikidza neyekutevedzana kwemakemikari maitiro. Inoratidza zvivakwa zvinobatsira, kusanganisira:
Kudzokorora kwemvura: HPMC inogona kuchengetedza mvura zvinobudirira, iyo inokosha mumadongo kuti isingadzivise kuomesa uye kuve nechokwadi che hydration yakakwana yezvishandiso zvekushandisa.
Rheology Shiology: Inoita seyekuita mumiririri, achivandudza vhiza uye kusawirirana kwemugadziri.
ADHesion: HPMC inosimudzira iyo inonamatira zvivakwa zvemutumbi, kubatsira mukushandisa pane zvimisikidzwa uye zvakananga nzvimbo.
Kushanda: Iyo Polymer inovandudza iyo EasE yekushandisa uye kupararira kweura.
Sag Kudzvinyirira: Inopa SAG Rwisa, kudzivirira iyo duri kubva mukutsvedza kana kusekerera panguva yekushandisa.
Mhepo inokwikwidza: HPMC inogona kumuka mhepo mumusanganiswa wemba, ichivandudza kupokana kwayo nechando uye kuderedza density.
Zvikumbiro mumuchina-wakaputika mongwe
Muchina-wakaputika muridzo, wakashandiswa zvakanyanya zvekushandura uye kupururudza nzvimbo huru, zvakanaka kubva mukubatanidzwa kweHPMC. Heino mafungu ekutanga:
1. Sprayable plaster uye kupa
HPMC inowedzera kuita kwespraable plasters uye majecha, ayo anoshandiswa achishandisa mashini ekupuruzira ekunyora nzvimbo dzakakura dzenzvimbo dzakakura. Maitiro ayo akakosha anosanganisira:
Kuvandudza Kusimbisirwa: HPMC inovimbisa kuti motwe inogona kuputirwa kuburikidza neyekuputira muchina pasina kuvhara kana kupfeka zvakawandisa pamidziyo.
Yunifomu yekushandisa: Inobatsira mukuzadzisa jasi remuoni, yakakosha kuti uwedzere kupedza uye kudzivirirwa.
Yakaderedzwa Rosha Kurasikirwa: Nekuvandudza kuderedza uye kuderedza Rebound, HPMC inosimbisa zvimwe zvinhu zvinogara pamadziro, kuderedza marara.
2. Kuzvibatanidza makomendi
Mukuzvimirira mauto, ayo akagadzirirwa kuyerera uye kugara mufurati, yakatsiga isina kudiwa kwekutsika-tsika, HPMC inotora basa rakakosha ne:
Kuvandudza Fluidity: Inoshandura iyo rheology, inoverengera iyo mongwe inoyerera zvakanaka uye ichizadza mapundu uye kushungurudzika.
Kudzora Kugara Nguva: HPMC inobatsira mukugadzirisa nguva yekugara, ichipa nguva yakakwana yekushanda ichiri kuita nguva nenguva.
Kudzivirira kusarongeka: Iyo inovimbisa kuti zvikamu zvemusanganiswa zvichagara zvakagoverwa zvakagoverwa, zvichidzivirira kupatsanurana.
3. Kunamatira Moriri
HPMC inoshandiswa mune inonamatira madhiri nemabhodhi ekusimbisa, kupa:
Yakavandudzwa ADHesion: Inosimbisa zvakanyanya bond Simba pakati pehudyu uye substrate kana tile.
Slump Rishance: Kuona mataira anogara munzvimbo pasina kutsvedza panguva yekuporesa.
Kushanda uye kusvinura nguva: Kuwedzera nguva yakavhurika (iyo nguva iyo matiles inogona kugadziriswa mushure mekushandisa), kuita iyo application maitiro anokanganwira uye anochinja-chinja.
4. Thermal insolation motsi
Kune motars inoshandiswa mune inopisa masisitimu masisitimu, HPMC inobatsira ne:
Kufambisa application: Kugadzira zviri nyore kushandisa mapuranga ekusimbisa kana machira akafanana.
Kuvandudza Chossion: Kuverengera kuti iyo yekunzvera zvinhu zvinoshatisa zvakanaka kune nzvimbo uye inopa isingadzivisike inosimbisa.
Kudzokorora kwemvura: Kuvandudza kurapa uye kuderedza njodzi yekukanganisa nekuda kwekukurumidza kurasikirwa kwemvura.
5. Kugadziriswa motsa
MuMartars inoshandiswa pakugadzirisa zvivakwa zvekongiri, HPMC AIDS ne:
Kuvandudza Kurovedzera: Kuverengera iyo yekugadzirisa iyo motsi inogona kuiswa mushe uye nenzira kwayo, kuzadza makatsemuka uye voids zvinobudirira.
Yakavandudzwa Adhisheni: Kupa kusungwa kwakasimba kune iripo kongiri, iyo yakakosha yekugadziriswa kwakasimba.
Kudzikira kuderedza: kuderedza kudzikira pakurapa, nekudaro kudzora njodzi yekuumbwa kwekupaza.
Zvinokosha Zvinofungidzirwa
Paunenge uchishandisa HPMC mumutengo wakaputirwa-muchina, zvimwe zvinonyatsofungidzirwa kuti zvinofanirwa kuchengetwa mupfungwa:
Dosage: huwandu hwakakodzera hweHPMC hunofanira kushandiswa kuzadzisa zvaunoda zvisina kufanira pasina kukanganisa simba nekuvimbika kwemutya.
Kuenderana: Izvo zvakakosha kuti uve nechokwadi chekuti HPMC inoenderana nezvimwe zvinowedzera uye zvikamu mumusanganiswa weimba.
Kusanganisa: Maitiro akakodzera ekusanganisa anofanira kuteverwa kuti atevedze zvizere iyo HPMC uye anozviparadzira zvakafanana mumusanganiswa mumusanganiswa wega wega.
Basa reHPMC mumutengo wakaputirwa nemabhinja unowedzera, uchisimudzira maitiro uye mashandiro emhando dzakasiyana dzemhando dzakasiyana dzemota. Kunyangwe nekuda kwekushandura, kupururudza, kuzvimiririra, kana kugadziriswa, HPMC inovimbisa kuti motokari inogona kuiswa zvakanaka uye zvinobudirira, ichipa nguva refu-refu uye migumisiro yemhando yepamusoro. Kugona kwayo kuvandudza kudzokorora kwemvura, kushandira, kuderedza, uye rheology kunoita kuti ive yakavanzika maitiro mune dzazvino maitiro, inovimbisa kuti zviyero zvakakura zvekushandisa zvinogona kuzadzikiswa uye kune chiyero chakakwirira. Semunhu matekinoroji anochinja, kushandiswa kweHPMC kunogona kuwedzera kuenderera mberi, kutungamirirwa nekuenderera mberi kwekutsvaga nekuvandudza mukugona kwayo uye mabhenefiti.
