Yakajairika uye yakapusa nzira dzekusiyanisa mhando yeHPMC cellulose

Yakajairika uye yakapusa nzira dzekusiyanisa mhando yeHPMC cellulose:

1. Mamiriro ekuona akachena HPMC cellulose ane fluffy, uye kuwanda kwehuwandu hudiki, hune huwandu hwe 0.3-0.4g / ml; Adlterated HPMC cellulose ine fluidity iri nani uye inorema ruoko inonzwa, iyo yakasiyana zvakanyanya nekuonekwa kwechokwadi zvigadzirwa.

2. Iko kuchena kweiyo yakachena HPMC cellulose yakanaka, zvinoreva kuti zvigadzirwa zvinoshandiswa mukugadzira zvakachena uye mabatiro acho anowedzera pasina tsvina. Zvichienzaniswa neakakodzera ekunze cellulose ether zvigadzirwa, zvinogona kuoneka kuti kuchena kweyakanaka cellulose ether chigadzirwa kunogara kuri nani pane iyo yepamba yechipiri-mutsara zvigadzirwa.

3. Pure HPMC cellulose aqueous solution yakajeka, ine high light transmittance, uye water retention rate ≥ 97%; Iyo yakasvibiswa HPMC cellulose aqueous solution ine turbid, uye mwero wekuchengetedza mvura unonetsa kuzadzisa zvinodiwa. Chiedza chekufambisa chemushonga wemvura wakanaka, izvo zvinoratidza kuti chigadzirwa chacho chine zvinhu zvisinganyanyi kunyungudika uye zvakakwirira zvezvinhu zvinoshanda.

4. Yakachena HPMC cellulose haifaniri kunhuwa ammonia, starch uye doro; Yakasvibiswa HPMC cellulose inogona kazhinji kunhuhwirira marudzi ese ekunaka. Kunyange kana isina kunaka, inonzwa ichirema.

5. Pure HPMC cellulose powder is fibrous under microscope kana magnifying glass; Iyo yakacheneswa HPMC cellulose inogona kucherechedzwa seyakaomarara kana kristaro pasi pemaikorosikopu kana girazi rinokudza.

6. Nzira yakapfava yekuedza yemadota e-cellulose ether: kuyera magiramu maviri e-cellulose ether, kuibatidza nechiedza, kuyera madota akasara akasiyiwa nekupisa kwe cellulose ether, uye kana madota asara / cellulose ether iri ≥ 5 %, mhando ye cellulose ether haina kukwana. (pane dzimwe nguva zvikanganiso munzira iyi. Chekutanga, mugadziri akawedzera zvigadzirwa zvakakodzera vatengi chaivo vasati vabva mufekitari; chechipiri, vamiririri kana vagadziri vakawedzera zvinhu zvinopfuta zvine madota mashoma pakusvibisa)

7. Mamwe mafekitari nedzimba dzinoshandisa shoma shoma yeC cellulose yakasanganiswa mu hydroxypropyl methyl cellulose ether, uye kana iyo aqueous solution yeC cellulose inosangana netin, sirivheri, aluminium, lead, iron, mhangura uye mamwe masimbi anorema, kunaya kwemvura kuchaitika; Kana c-cellulose aqueous solution ikabatana necalcium, magnesium nemunyu, haizobudisi kunaya, asi inoderedza viscosity ye c-cellulose aqueous solution.

8. Kana mamiriro ezvinhu achibvumidza, edza zvakananga viscosity yeaqueous solution ye cellulose ether uye enzanisa mwero wekuchengetedza mvura we low content cellulose ether mortar.

Senyanzvi yekugadzira cellulose ether, Youngcel cellulose ichapa nemoyo wese vatengi zvigadzirwa zvemhando yepamusoro uye masevhisi
