Taura nezve cellulose ethers

01. Iko kushandiswa kukuru kwe cellulose ether HPMC?

HPMC inoshandiswa zvakanyanya mukuvaka dhaka, pendi yemvura, resin yekugadzira, ceramics, mushonga, chikafu, machira, zvizorwa, fodya, uye mamwe maindasitiri. Yakakamurwa kuita giredhi rekuvaka, giredhi rekudya, giredhi remishonga, PVC giredhi reindasitiri uye giredhi remakemikari zuva nezuva.

02. Ndezvipi zvikamu zve cellulose?

Maselulosi akajairika ndiwo MC, HPMC, MHEC, CMC, HEC, EC
Pakati pavo, HEC neCMC inonyanya kushandiswa mumvura-based coatings,
CMC inogona zvakare kushandiswa mumakeramiki, munda wemafuta, chikafu uye mamwe minda
EC inonyanya kushandiswa mukurapa, zvemagetsi sirivheri paste uye mamwe minda
HPMC rakakamurwa siyana nokurondedzerwa nokuda dhaka, mushonga, zvokudya, PVC indasitiri, zuva nezuva makemikari zvigadzirwa uye mamwe maindasitiri.

03. Ndeupi musiyano uripo pakati peHPMC neMHEC mukushandisa?

Zvimiro zvemhando mbiri dze cellulose zvakangofanana, asi kugadzikana kwekushisa kweMHEC kuri nani, kunyanya muzhizha kana tembiricha yemadziro yakakwira, uye kuchengetedza kwemvura kweMHEC kuri nani pane kweHPMC pasi pemamiriro ekushisa kwakanyanya. .

04. Nzira yekungotonga sei kunaka kweHPMC?

1) Kunyangwe kuchena kusingakwanise kuona kana HPMC iri nyore kushandisa, uye kana maajenti ekuchena akawedzerwa mukuita kwekugadzira, mhando ichakanganiswa, asi mazhinji ezvigadzirwa zvakanaka zvine kuchena kwakanaka, izvo zvinogona kutongwa zvishoma kubva pakuonekwa.
2) Chiedza chekufambisa: Mushure mekunyungudutsa HPMC mumvura kuti iite yakajeka colloid, tarisa kune yayo mwenje transmittance. Iyo iri nani iyo mwenje wekufambisa, iyo isinganyunguke chinhu chiripo, uye mhando yacho yakanaka.
Kana iwe uchida kutonga nemazvo kunaka kwe cellulose, nzira yakavimbika ndeye kushandisa michina yehunyanzvi murabhoritari yehunyanzvi yekuongorora. Iwo makuru ekuyedza zviratidzo anosanganisira viscosity, chiyero chekuchengetedza mvura, uye madota.

05. Kuyera seiviscosity ye cellulose ether?

Iyo yakajairwa viscometer mumusika we cellulose wepamba iNDJ, asi mumusika wepasi rose, vagadziri vakasiyana vanowanzo shandisa nzira dzakasiyana dzekuyedza viscosity. Izvo zvakajairika ndezve Brookfeild RV, Hoppler, uye kune zvakare akasiyana ekuona mhinduro, ayo akakamurwa kuita 1% mhinduro uye 2% mhinduro. Akasiyana maviscometers uye akasiyana nzira dzekuona dzinowanzo konzera mutsauko wekakati wandei kana kunyange makumi enguva mumhedzisiro yeviscosity.

06. Ndeupi musiyano uripo pakati peHPMC instant type uye inopisa melt type?

HPMC's instant products zvinoreva zvigadzirwa zvinokurumidza kupararira mumvura inotonhora, asi zvinofanirwa kucherechedzwa kuti kupararira hakureve kuparara. Zvigadzirwa zvepakarepo zvinobatwa ne glyoxal pamusoro uye zvakaparadzirwa mumvura inotonhora, asi hazvitangi kunyungudika pakarepo. , saka viscosity haina kugadzirwa pakarepo mushure mekupararira. Iyo yakakura kuwanda kweiyo glyoxal pamusoro pekurapa, kukurumidza kupararira, asi kunononoka viscosity, kudiki kuwanda kweglyoxal, uye zvinopesana.

07. Compound cellulose uye yakagadziridzwa cellulose
Ikozvino kune akawanda akagadziridzwa cellulose uye akakoniwa cellulose pamusika, saka chii chinonzi kugadziridzwa uye komputa?

Rudzi urwu rwe cellulose kazhinji rune zvimiro izvo cellulose yepakutanga haina kana kuwedzera zvimwe zvezvinhu zvayo, zvakadai se: anti-slip, yakasimbiswa nguva yakazaruka, yakawedzera nzvimbo yekukwenya kuvandudza kuvaka, etc. Zvisinei, zvinofanira kuonekwa kuti makambani mazhinji. shandisawo Iyo yakachipa cellulose yainosvibisa kuitira kuderedza mutengo inonzi kompani cellulose kana yakagadziridzwa cellulose.
