Hydroxy ethyl methyl cellulose

Hydroxy ethyl methyl cellulose (HEMC), inozivikanwawo semethyl hydroxy ethyl cellulose (MHEC), i polymer inoshanda zvakasiyana-siyana inotorwa kubva muselulosi.Iyo inogadzirwa kuburikidza nekugadziriswa kwekemikari ye cellulose, zvichikonzera komboni ine yakasarudzika zvivakwa inokodzera akasiyana maindasitiri ekushandisa.HEMC inhengo yemhuri yecellulose ether uye inogovana zvakafanana nezvimwe zvinobva semethyl cellulose (MC) uye hydroxypropyl methyl cellulose (HPMC).

Zvinhu Zvinokosha zveHydroxy ethyl Methyl Cellulose (HEMC):

1.Water Solubility: HEMC inonyungudika mumvura, ichiita mhinduro dzakajeka uye dzakajeka.Ichi chivakwa chinobvumira kubata nyore uye kubatanidzwa mune aqueous masisitimu, zvichiita kuti ive yakakodzera kushandiswa mumhando dzakasiyana dzemagadzirirwo.

2.Thickening Agent: HEMC inoshanda sechinhu chinobudirira thickening agent mumvura-based formulations.Kana yanyungudutswa mumvura, macheni epolymer eHEMC anonamira uye anoumba network network, kuwedzera viscosity yemhinduro.Ichi chivakwa chakakosha pakudzora rheology uye kuyerera zvimiro zvependi, zvinonamira, uye zvimwe zvigadzirwa zvemvura.

3.Film-Forming Ability: HEMC ine simba rekugadzira mafirimu kana yakashandiswa panzvimbo uye inobvumirwa kuoma.Aya mafirimu akajeka, anochinjika, uye anoratidza kunamatira kwakanaka kune akasiyana substrates.HEMC mafirimu anoshandiswa mukushandisa senge machira, zvinonamira, uye zvekuvaka.

4.Enhanced Water Retention: HEMC inozivikanwa nokuda kwekuchengetedza mvura, iyo inobatsira kudzivirira kurasikirwa kwemvura uye kuchengetedza kudiwa kwekugadzirisa kwekugadzirisa kwenguva.Ichi chivakwa chinonyanya kubatsira mukuvaka senge madhaka, grouts, uye mataira anonamira, uko kushanda kwenguva refu kunodiwa.

5.Improved Workability and Adhesion: Kuwedzerwa kweHEMC kune zvinyorwa zvinogona kuvandudza kushanda nekusimudzira kuyerera uye kupararira kwezvinhu.Inosimudzirawo kunamatira kune substrates, zvichitungamira kune zvirinani kubatana uye kuita kwechigadzirwa chekupedzisira.

6.Kugadzikana kweEmulsions uye Suspensions: HEMC inoshanda seyakagadzikana mu emulsions uye suspensions, kudzivirira kuparadzaniswa kwechikamu uye kugadzirisa zvikamu.Ichi chivakwa chinobatsira kuchengetedza homogeneity uye kugadzikana kwezvigadziriso, kuve nechokwadi chinowirirana chigadzirwa mhando.

7.Kuenderana nemamwe maAdditives: HEMC inowirirana nehuwandu hwemamwe makemikari uye zvinowedzera, kusanganisira pigments, fillers, uye rheology modifiers.Inogona kuiswa nyore nyore mumagadzirirwo akaomarara kuti uwane inodiwa maitiro ekuita.

Zvishandiso zveHydroxy ethyl Methyl Cellulose (HEMC):

1.Kuvaka Zvishandiso: HEMC inoshandiswa zvakanyanya muindasitiri yekuvaka seyakakora, mumiriri wekuchengetedza mvura, uye binder mune samende-based mortars, plasters, uye tile adhesives.Inonatsiridza kushanda, kunamatira, uye sag kuramba kwezvinhu izvi, zvichiita kuti iwedzere kuita uye kusimba.

2.Paints uye Coatings: HEMC inoshandiswa se rheology modifier, thickener, uye stabilizer mumvura-based paints, coatings, uye ingi.Inokwidziridza kupararira kwepigment, inodzivirira kusagika, uye inovandudza mashandisirwo ezvimiro zveiyi magadzirirwo.

3.Adhesives uye Sealants: HEMC inoshandiswa mukunamatira uye sealants kuvandudza simba rekubatanidza, tack, uye nguva yakazaruka.Iyo inoshandawo seyakakora mumiriri uye rheology modifier, ichipa inodiwa viscosity uye kuyerera zvivakwa zvekushandisa.

4.Personal Care Products: HEMC inowana zvikumbiro muzvigadzirwa zvekutarisira zvemunhu zvakadai semafuta, lotions, uye shampoos semukobvu, stabilizer, uye firimu yekare.Inopa inodiwa manyorerwo, kuenderana, uye rheological zvimiro kune aya magadzirirwo.

5.Pharmaceuticals: Mukugadzirwa kwemishonga, HEMC inoshanda sebhainda, disintegrant, uye inodzorwa-inosunungura mumiririri mumapiritsi, capsules, uye mafuta.Iyo biocompatibility uye kunyungudika kwemvura kunoita kuti ive yakakodzera kumuromo uye wepamusoro kunyorera.

6.Indasitiri Yezvekudya: Kunyange isingawanzowanzi, HEMC inoshandiswawo muindasitiri yezvekudya seyakakora, stabilizer, uye emulsifier mune zvimwe zvigadzirwa senge sosi, madhirezi, uye madhiri.

Hydroxy ethyl Methyl Cellulose (HEMC) i polymer inoshanda zvakasiyana-siyana ine akasiyana maapplication mumaindasitiri akati wandei.Kunyungudika kwayo kwemvura, kukora zvivakwa, kugona kugadzira firimu, uye kuenderana nezvimwe zvinowedzera zvinoita kuti ive yakakosha mukuvaka, pendi uye machira, zvinonamira, zvigadzirwa zvekuchengeta munhu, mishonga, uye kugadzira chikafu.Sezvo kutsvagisa nekusimudzira kuedza kuri kuenderera mberi, HEMC inotarisirwa kuita basa rinowedzera kukosha mumaitiro emazuva ano maindasitiri.
