Hydroxypropyl methyl cellulose, unozviziva here?

1.HPMCyakakamurwa kuva mhando yekukurumidza uye mhando yekukurumidza kupararira.

Rudzi rweHPMC fast dispersion rune bhii S, uye glyoxal inofanira kuwedzerwa panguva yekugadzira.

Rudzi rweHPMC instant haruwedzere mabhii, akadai sekuti “100000″ zvinoreva “100000 viscosity.”

2. Kana paine kana pasina S, hunhu hwacho hwakasiyana

HPMC inopararira nekukurumidza inopararira nekukurumidza kana yasangana nemvura inotonhora yobva yanyangarika mumvura. Panguva ino, mvura yacho haina viscosity, nekuti HPMC inongopararira mumvura isina kunyungudika chaiko. Mushure memaminitsi angangoita maviri, viscosity yemvura inowedzera zvishoma nezvishoma, zvichiita kuti ive colloid yakajeka ine viscosity.

HPMC inokurumidza inogona kuparadzirwa nekukurumidza mumvura inopisa panosvika 70°C. Kana tembiricha yadzikira kusvika patembiricha yakati, viscosity inoonekwa zvishoma nezvishoma kusvika yaumbwa colloid yakajeka ine viscous.

3. Chinangwa chakasiyana neS kana kuti kwete

HPMC Instant inogona kushandiswa chete muupfu hweputty nemortar. Muglue yemvura, pendi uye zvinhu zvekuwachisa, pachava nezviitiko zvekuisa mumapoka uye hazvigone kushandiswa.

Inopararira nekukurumidzaHPMCine mashandisirwo akasiyana-siyana uye inogona kushandiswa mupudhi yeputty, mortar, liquid glue, pendi, uye zvinhu zvekuwachisa pasina chero chipingamupinyi.

4. Nzira yekunyungudutsa

4-1. Tora huwandu hunodiwa hwemvura inopisa, uiise mumudziyo woipisa kusvika pamusoro pe80°C, wobva wawedzera chigadzirwa ichi zvishoma nezvishoma uchikurunga zvishoma nezvishoma. Cellulose inoyangarara pamusoro pemvura pakutanga, asi inopararira zvishoma nezvishoma kuti iite slurry yakafanana. Mushonga wacho waitonhodzwa uchikurunga.

4-2. Neimwe nzira, pisa 1/3 kana 2/3 yemvura inopisa kusvika pamusoro pe85°C, wedzera cellulose kuti uwane slurry yemvura inopisa, wobva wawedzera mvura inotonhora yasara, ramba uchikurunga, wotonhodza musanganiswa wacho.

4-3. Mesh ye cellulose yakanaka, uye inowanikwa sezvidimbu zvidiki zvakasiyana muupfu hwakasanganiswa zvakaenzana, uye inonyunguduka nekukurumidza kana yasangana nemvura kuti igadzire viscosity inodiwa.

4-4. Wedzera cellulose zvishoma nezvishoma patembiricha yemumba, woramba uchikurunga kusvika mvura yabuda pachena.

5. Ndezvipi zvinhu zvinokanganisa kuchengetwa kwemvura kwehydroxypropyl methyl cellulose?

5-1. Kuenzana kwe ether ye cellulose HPMC

HPMC, methoxyl nehydroxypropoxyl zvine reactive zvakaenzana zvakapararira zvakaenzana, uye mwero wekuchengetedza mvura wakakwira.

5-2. Tembiricha yemafuta emuchina weCellulose ether HPMC

Kana tembiricha yekupisa yegel yakakwira, mwero wekuchengetedza mvura wakakwira; zvikasadaro, mwero wekuchengetedza mvura wakaderera.

5-3. Cellulose Ether HPMC Viscosity

Kana viscosity yeHPMC ikawedzera, mwero wekuchengetedza mvura unowedzerawo; kana viscosity yasvika padanho rakati, kuwedzera kwemwero wekuchengetedza mvura kunowanzova kushoma.

6. Kuwedzera huwandu hwe cellulose ether HPMC

Huwandu hwe cellulose ether hwakakuraHPMCZvinowedzerwa kuti, mwero wekuchengetedza mvura wakakwira uye mhedzisiro yekuchengetedza mvura iri nani.

Pakati pe0.25-0.6%, mwero wekuchengetedza mvura wakawedzera nekukurumidza nekuwedzera kwehuwandu hwekuwedzera; apo huwandu hwekuwedzera hwakawedzera, mwero wekuwedzera kwehuwandu hwekuchengetedza mvura wakadzikira.
