Chii chaunoziva nezve cellulose ther?

1. Iko kushandiswa kukuru kwe cellulose ether hpmc?

HPMC inoshandiswa zvakanyanya mukuvaka, pendi-yakavakirwa mvura, ceramices, ceramics, mushonga, chikafu, zvidhori, fodya, uye mamwe maindasitiri. Iyo yakakamurwa kuita giredhi rekuvaka, giredhi rekudya, pharmaceutical giredhi, PVC Indasitiri giredhi uye zuva nezuva Chemical giredhi.

2. Ndezvipi zvirongwa zve cellulose?

Commen celluloses ari mc, hpmc, mhec, cmc, hec, ec

Pakati pavo, hec uye cmc vanonyanya kushandiswa mumvura yakavakirwa mvura;

CMC inogona zvakare kushandiswa mumakaramu, minda yemafuta, chikafu nedzimwe minda;

EC inonyanya kushandiswa mumushonga, sirivha yesirivha yesirivha uye imwe minda;

HPMC yakakamurwa kuita zvakasiyana siyana uye inoshandiswa mudhaka, mushonga, chikafu, pvc indasitiri, zvigadzirwa zveMitambo zveMakemikari uye mamwe maindasitiri.

3. Ndeupi musiyano uripo pakati peHPMC uye MHEC mukushandisa?

Zvivakwa zvemhando mbiri dzemasero zvakanyatsofanana, asi iyo yakanyanya kupisa tembiricha iri nani, kunyanya muzhizha apo tembiricha yakakwirira, uye yekuchengetwa kwemvura yeMheC iri nani pane iyo yeHPMC iri pasi pemamiriro ekunze ekushisa .

4. Sei kungotonga kunaka kweHPMC?

2) Kuputika kwechiedza: Mushure mekunyungudika HPMC mumvura kuti ugadzire yakajeka colod coloid, tarisa kujekesa kwayo. Zviri nani kupanduka kwechiedza, iyo isinganyanye kusagadzikana nyaya iripo, uye kunaka kuri kwakanaka.

Kana iwe uchida kutonga chaizvo mhando ye cellulose, iyo nzira yakavimbika kwazvo ndeye kushandisa nyanzvi yemidziyo mune nyanzvi yehunyanzvi hwekuongororwa kwekuedza. Iyo huru yekuyedza zviratidzo zvinosanganisira viscosity, kudzokorora kwemvura, uye kugutsikana kwechiSH.

5. Maitiro ekuyera vhiza ye cellulose?

Iyo yakajairika viscomerer mumusika weCellulose mudzimba ndi NDJ, asi mumusika wepasi rose, vagadziri vepasi rose vanowanzo shandisa nzira dzakasiyana dzekuona viscosity. Izvo zvinozivikanwa ndiBrookfild RV, Hopler, uye kune zvakare mhinduro dzakasiyana dzekuona, dzidzo dzakakamurwa kuita 1% mhinduro uye 2% mhinduro. Vakasiyana vhiza uye nzira dzakasiyana dzekuona dzinowanzoguma nemusiyano kakawanda kana kunyange kazhinji nguva dzakawanda mumhedzisiro yemisangano.

6. Ndeupi musiyano uripo pakati peHPMC Instant Type uye Hot Melt Type?

Hpmc's Zvigadzirwa Zvekushandisa zvinoreva zvigadzirwa zvinokurumidza kupararira mumvura inotonhora, asi inofanira kucherechedzwa kuti kupararira hazvireve kupaza. Zvigadzirwa zvekunze zvinobatwa neGlyoxal pamusoro uye akapararira mumvura inotonhora, asi ivo havatangi kunyungudika nekukurumidza. , saka viscosity haina kuburitswa pakarepo mushure mekupararira. Iyo yakakura kwazvo huwandu hwenyika yeGyoxal pamusoro pekurapwa, inokurumidza kupararira, asi inononoka zvisizvo, idiki huwandu hweGlyoxal, uye zvinopesana.

7. Compound Celleulose uye yakagadziridzwa cellulose

Ikozvino kune yakawanda yakagadziridzwa cellulose Cellulose uye cellow cellulose pamusika, saka kugadziridzwa uye kuumbwa?

Rudzi urwu rwemasero runowanzove nezvivakwa zvekuti mafuro ekutanga asina kana kuwedzeredza zvimwe zvezvivakwa zvaro, zvakadai: SHANDISA SEI SEAP COLCEULOSE IYO IZVO ZVINOGONESESA KUTI VADZIDZE MAHARA inonzi Consuund Cellulose kana yakagadziridzwa cellulose. Semutengi, edza kusiyanisa uye kusanyengedzwa. Zvakanaka kusarudza zvigadzirwa zvakavimbika kubva kune hombe mabhurawu uye mafekitori makuru.
