Iko kushandiswa kukuru uye kusiyana kwehydroxypropyl methylcellulose HPMC uye hydroxyethyl cellulose HEC

Carboxymethyl cellulose, hydroxypropyl methyl cellulose, uye hydroxyethyl cellulose ine maindasitiri monosodium glutamate anoshandiswa muhuwandu hukuru.Chinonyanya kuoma kusiyanisa pakati pemhando nhatu idzi dze cellulose ihydroxypropyl methylcellulose uye hydroxyethyl cellulose.Pazasi isu tichasiyanisa aya marudzi maviri e cellulose kuburikidza nekushandisa kwavo uye basa.

Senge isiri-ionic surfactant, hydroxyethyl cellulose ine zvinotevera zvivakwa mukuwedzera kune mabasa ekumisa, kukora, kuparadzira, kuyerera, kusungirira, kugadzira firimu, kuchengetedza mvura uye kupa inodzivirira colloid:

1. HEC pachayo haisi-ionic uye inogona kugarisana nemamwe akawanda-anonyungudika mapolymers, surfactants, uye munyu.Iyo yakanakisa colloidal thickener yemhinduro dzine high-concentration electrolytes.

2. Kuenzaniswa neyakazivikanwa methyl cellulose uye hydroxypropyl methyl cellulose, kukwanisa kuparadzira kweHEC ndiko kwakaipisisa, asi kukwanisa kwekudzivirira kwecolloid ndiyo yakasimba.

3. Kukwanisa kwekuchengetedza mvura kwakapetwa kaviri kune iyo yemethyl cellulose, uye ine zviri nani kuyerera kwemutemo.

4. HEC inonyungudika mumvura inopisa kana mvura inotonhora, uye hairegi pakupisa kwepamusoro kana kubikira, iyo inoita kuti ive nehuwandu hwekunyungudika uye viscosity maitiro, uye kwete-thermal gelation.

HEC kushandiswa: inowanzoshandiswa seyakakura, inodzivirira, inonamatira, stabilizer uye kugadzirira emulsion, jelly, mafuta, lotion, ziso rakajeka.

Hydroxypropyl methylcellulose (HPMC) sumo yekushandisa:

1. Indasitiri yekuputira: Inoshandiswa seyakakura, inoparadzanisa uye yakagadzikana mumhizha yekuputira, uye ine kuwirirana kwakanaka mumvura kana organic solvents.Sekubvisa pendi.

2. Ceramic kugadzira indasitiri: Inoshandiswa zvakanyanya sebhainda mukugadzira zvigadzirwa zveceramic.

3. Vamwe: Ichi chigadzirwa chinoshandiswawo zvakanyanya mumatehwe, zvigadzirwa zvemapepa, kuchengetedza michero nemiriwo uye maindasitiri emachira, nezvimwe.

4. Ink kudhindwa: Inoshandiswa seyakakora, dispersant uye stabilizer muindasitiri yeinki, uye ine kuenderana kwakanaka mumvura kana organic solvents.

5. Plastiki: inoshandiswa sekugadzira kuburitsa agent, softener, lubricant, nezvimwe.

6. Polyvinyl chloride: Inoshandiswa seanoparadzira mukugadzirwa kwepolyvinyl chloride, uye ndiyo inonyanya kubatsira mumiririri wekugadzira PVC nekumisa polymerization.the

7. Indasitiri yekuvaka: Semugadziri wekuchengetedza mvura uye retarder yesamende jecha slurry, inogona kuita kuti dhaka ripombike.Mupurasita, gypsum, putty poda kana zvimwe zvekuvaka sechibatiso chekuvandudza kupararira uye kurebesa nguva yebasa.Inogona kushandiswa sekuisa mataira, marble, kushongedzwa kwepurasitiki, paste yekusimbisa, uye inogona zvakare kuderedza huwandu hwesimende.Kuita kwekuchengetedza mvura kweHPMC kunodzivirira slurry kubva pakutsemuka nekuda kwekuoma nekukurumidza mushure mekushandisa, uye inowedzera simba mushure mekuoma.
