Kushandiswa kwehydroxyprishlpyl methyl cellelose muzvivakwa zvekuvaka

Hydroxypruppyl methyl cellulose (HPMC)Inosimudziro yakati wandei inowana mashandiro akawanda muindasitiri akasiyana-siyana, kusanganisira iyo yekuzvidza coatings chikamu. Muzvivakwa zvezvivakwa, HPMC inoshandisa zvinangwa zvakawanda, zvichikonzera kugadzikana kweiyo fomu yekuumbwa, kuita uye hunhu hwese.

1. Rheology shanduko:
Imwe yemabasa ekutanga eHPMC muzvivakwa zvezvivakwa ndeye rheology shanduko. HPMC inoita seyekuita mumiririri, uchivandudza zvevishuwa zvechikanda. Nekugadzirisa iyo viscosity, HPMC inobatsira mukudzora kuyerera uye huwandu hwezvivakwa zvekuvhara panguva yekushandisa. Izvi zvinovimbisa kufukidzwa kwunifomu, kuderedza kudonha, uye kunowedzera kufadza kwekunyepedzera kweiyo yakafukidzwa.

2. Kuchengeta mvura:
HPMC ine simba rakanakisa kuchengetedza kwemvura, izvo zvinonyanya kubatsira pakuvaka marara. Nekuchengetedza mvura mukati meiyo fomu, HPMC inowedzera nguva yakavhurika yekubatanidza, kubvumira kushanda zviri nani uye zvakavandudzwa zvinyorwa zvekushandisa. Izvi zvinonyanya kukosha mune mamiriro ezvinhu apo iyo inokwereta inoda nguva yakakwana yekukwana kana kuzvimiririra usati waoma.

3. Film Ford:
Muzvakagadzirwa zvezvivakwa, kuumbwa kweyunifomu uye firimu rakasimba kunokosha pakuita kwenguva refu. HPMC AIDS muFirimu kuumbwa nekusimudzira iyo coallescence yePolymer zvikamu mukati merating matrix. Izvi zvinoguma nefirimu rakatsetseka uye rinowedzera, rinowedzera kusimba, kuderedza, uye kuramba kurwisa kuungana.

4. Sag Kudzivisa:
Sag kupokana inzvimbo yakaoma yezvivakwa mune yekuvaka yejasi, kunyanya kune nzvimbo dzakarongedzwa.HpcInoridza anti-sag-sag yekuvhara, ichidzivirira kubva mukutsvaira kana kudonha zvakanyanya panguva yekushandisa. Izvi zvinovimbisa kuti kuunganidza kunokwana kwunifomu pamusoro pevatikisi nzvimbo, kudzivisa mitsipa isina kunaka kana kumhanya.

5. STabilization:
HPMC inoshanda seyekutsvaira mumakororo ekuvaka, kudzivirira chikamu chekuparadzaniswa, kugadzirisa, kana kugera kwemaficha uye zvimwe zvinowedzera mukati meiyo tsika. Izvi zvinobatsira kuchengetedza iyo homogeneity uye kusawirirana kwekubatanidza, kunoita kuti kuonekera kwemari uye kutaridzika kwematanho akasiyana.

6. Kuvandudza Dhizimusi:
ADhemon ari paramount muzvivakwa zvekuvaka kuti ave nechokwadi chekusingaperi-kusingaperi kushungurudzika kune akasiyana substrates. HPMC inovandudza iyo yekunamatira zvivakwa zvejasi nekuumba chisungo chakasimba pakati pekucheka uye nzvimbo yepamusoro. Izvi zvinosimudzira kushamisika kuri nani, kunoderedza mukana wekugadzikana kana kupfava, uye unowedzera kujairwa kwakazara kweiyo yekubatanidza system.

7. Kufungisisa kwekutsigira:
HPMC inozivikanwa nekuda kwehunhu hwayo hwehukama hunhu, uchiita sarudzo inokwezva yezvivakwa zvekugadzira mafambiro ekugadzira. Iyo biodegradable, isiri-ine chepfu, uye haina kukuvadza kuzivikanwa kweiyo organic compound (VERCS). Sezvinoratidzwa nemitemo yezvakatipoteredza inowedzera kukosha muCatings Indasitiri, kushandiswa kweHPMC inoenderana nemaindasitiri ekuedza kugadzira eco-hushamwari zvigadzirwa.

HydroxyPropyl methyl cellel Cellelose (HPMC) inoita basa rekuvaka, kugovera kwakasiyana siyana kusanganisira renhema Kuedza kwaro uye kushanda kunoita kuti ive sarudzo yaunosarudza kune vagadziri kutsvaga kuti vagadzirise mashandiro, kusimba, uye kusimba kwekuzvidzivirira kwemakosi ezvivakwa. Sezvo maCoatings indasitiri inoshanduka-shanduka, HPMC inogona kuramba iri yakakosha musanganiswa mukuvandudzwa kwemhando yepamusoro uye zvakatipoteredza zvine mutoro wekubatanidza mafambiro ekubatanidza.
