Ndeipi basa rehekisi mumakonzo?

Iyo HEC (HydroxyTHETH Cellelose) inoita basa rakakosha muzviyo, vachishandira mabasa akasiyana siyana vanobatsira mukuita kwakazara uye kunaka kwechigadzirwa chinobatanidza.

Nhanganyaya yeHEC mumakonzo:
HydroxytHyl Cellulose (Hek) is is is is is is is is is-ionic mvura-yakasarudzika polymer yakawanikwa kubva ku cellulose. Zvivakwa zvaro zvakasarudzika zvinoita kuti ive inoshanda zvinoshandiswa mumasango akasiyana siyana, kusanganisira majasi. Mujasi, hec anoshanda seanodayera modifier, akasangana, stabilizer, uye firimu raimbova, pakati pemamwe mabasa. Yayo moleky chimiro, icho chinoratidza mapoka ehydrophic, inobvumira kuti iite kupindirana nemvura uye zvimwe zvikamu mukuumbwa kwehukama.

Rheology Kugadziridzwa:
Imwe yemabasa ekutanga ehec mumakonzo ndeye rheology shanduko. Rheology inoreva kudzidza kwekuti zvinhu zvinoyerera sei uye deform, uye zvinotora basa rakakosha mukutsanangura zvivakwa zvekushandisa uye kutaridzika kwekupedzisira kwejasi. Hec inobatsira kudzora iyo visikopa uye kuyerera maitiro ezvipfeko, kunoita kuti application chaiyo, kukwirira, uye kuumbwa kwefirimu. Nekugadzirisa kusungwa kwehwanda mune fomu, vagadziri vanogona kugadzirisa zvivakwa zvetsiva kuti zvisangane zvakananga application zvinodiwa.

Akakora Agent:
Hec inoshanda seyekubudirira mumiririri akakora mujasi mafomu. Kugona kwayo kuwedzera viscosity kunobvumira kumiswa kuri nani kwezvidimbu zvakasimba, kudzivirira kugadzirisa uye kuona yunifomu kugoverwa mukati meiyo coating. Ichi chivakwa chinonyanya kukosha mukuumbwa chine pigment, mafirita, kana zvimwe zvinowedzera zvinowedzera. Pamusoro pezvo, chiito chakakora chehec chinobatsira kuvandudza kuvaka uye kufukidzwa kwekucheka, zvichikonzera kupedzisa, kwakanyanya kupedzisa.

Stabilization:
Mune majasi ejasi emvura, kugadzikana kwakakosha kudzivirira kuparadzaniswa kweheti, kuumbwa, kana zvimwe zvinoshamisa kuchinja nekufamba kwenguva. HEC inoita seStabilizer nekuumba iyo collive collid yakatenderedza zvikamu, ichivadzivirira kubva mukuwedzera kana kugadzirisa kunze kwemhinduro. Izvi zvinowedzera hupenyu hwesherufu uye kuchengetwa kugadzikana kwechigadzirwa chinobatanidza, kuvimba nekusaenderana kwekuita kubva kubhoki kuti batch.

Film Ford:
HEC inopa kune iyo firimu-inoumba zvivakwa zvejasi, kutamba chikamu mukuumbwa kweiyo inoenderera uye yunifomu firimu pane iyo substrate. Sezvo inovhara madhiri, hec mamorekuru anozvironga pachavo kuti vagadzire network inosunga zvimwe zvikamu pamwechete. Iyi dhizaini network inobatsira kuvandudza kudiwa, kusimba, uye kuramba kunyengedzwa uye zvimwe zvinhu zvemunharaunda. Iyo firimu yakaumbwa nehec zvakare inokwidziridza kutaridzika kwekucheka, kupa zvakapfava uye kupedzisa kupedzisa.

Kuchengeta mvura:
Coatings dzinowanzo pukuta kana kurapa maitiro ekuumba firimu rakasimba pane substrate. Munguva yezviitiko izvi, mvura inobuda kubva mukuvhara, inotungamira kuchinja muViscosity uye maitiro eRheological. Hec inobatsira kuchengetedza kudzokorora kwemvura muCoating kuumbwa, kusimbirira nguva yekuomesa uye kubvumira kuyerera kuri nani uye kuyerera. Izvi zvinonyanya kubatsira pakushandisa nguva dzakatambanudzwa nguva yekuvhurika kana kuvandudzwa basa rinodiwa, sekukosheswa kwekushongedza kana kuti makatumbha.

Kuenderana:
HEC inoratidza yakanyanya kuwirirana nehuremu hwakawanda hweimwe hungwaru hunoshandiswa, kusanganisira zvisungo, solvent, pigments, uye zvinowedzera. Yayo isiri-ionic nature inovimbisa kuwirirana neese catic uye anionic zvikamu, zvichiita kuti zviite kuti zvive kushandiswa mukushandiswa kwakasiyana siyana. Izvi zvinoshanda zvinobvumirana zvinobvumidza maFlogulators kuti uwane zvaunoda maitiro maitiro pasina kubayira kuenderana kana kugadzikana.

Zvemamiriro ekunze uye hutano kufunga:
HEC inoonekwa seyakachengeteka uye yakatipoteredza inoshatiswa mune majasi ejasi. Iyo inotorwa kubva kune imwe nzvimbo yekuvandudza cellulose maseru uye haina kuisa huwandu hwehutano hwehutano kana ichishandiswa sezvakarairwa. Pamusoro pezvo, hec iri biohandura, zvinoreva kuti inokatyora zvakasikwa nekufamba kwenguva pasina kuunganidza nharaunda. Izvi zvinhu zvinobatsira kugamuchirwa kwaro uye kushandiswa mumatanda ekunyorera, kunyanya mumaindasitiri emaindasitiri ekuchengetedza uye ekuzvinyudza kutevedzera zvinhu zvekutanga.

HydroxytHyl Cellulose (HEC) inoita basa rakawanda muzviyo, kushanda se rheology modifier, mumiririri wakakora, stabilizer, firimu raimbova mumiririri. Yayo yakasarudzika yemidziyo inoita kuti ive yakakosha musanganiswa mune dzakasiyana-siyana yekubatanidza mafambiro, kuita seyekudzora maitiro ekuita, senge viscosity kudzora, kugadzikana, kuumbwa kwefirimu, uye kuenderana kwezvakatipoteredza. Sezvo maCoatings indasitiri inoenderera mberi nekuchinja, hec inotarisirwa kuramba iri chinhu chakakosha mukuvandudzwa kwemhando yepamusoro uye inogara inovhara zvigadzirwa.
