Ndezvipi zvinhu zvema cellulose etana?

Cellulose ersana boka renhengo dzemvura-dzinotsemuka dzemvura dzakatorwa kubva kuCellulose, polymer yakasikwa inowanikwa mumasero emaruva ezvirimwa. Aya ma cellulose ana avanoshandurwa kuburikidza nemakemikari maitiro ekupa chaiyo zvinhu zvinovaita kuti vabatsire muzvishandiso zvakasiyana siyana zveindasitiri. Mamwe ma cellulose etherulose ethyl celllose (mc), hydroxyprosl cellulose (HPC), hydroxytl cellulose (Hec), uye hydroxyprosl methelose (HPMC). Zvivakwa zveCellulose anaiters zvinokonzerwa nemakemikari mavo emakemikari uye degree rekutsiva. Heano mamwe general general midziyo ye cellulose etana:

1. Soluby mvura:

• Cellulose eter inoratidza yakanakisa mvura salubility, ichiita kuti vakwanise kushandisa kushandiswa mumvura-yakavakirwa mvura. Ichi chivakwa chinobvumidza kupererwa kuri nyore kuita masisitimu akasiyana siyana, akadai sekupenda, anoshambidza, uye mafomu ezvimedu.

2. Firimu-kugadzira kugona:

• Vazhinji cellulose vainaro vanokwanisa kuumba mafirimu kana mhinduro yePolymer yaoma. Ichi chivakwa chinonyanya kubatsira mukushandisa zvakadai sejasi, uko kuumbwa kwefirimu rekudzivirira kunodiwa.

3. Kukoshesa uye rheology shanduko:

• Cellulose ana vana vanoshanda zvakanaka uye rheology modifiers. Vanogona kuwedzera iyo visikopa yemhinduro uye kupa kutonga pamusoro peiyo inoyerera zvivakwa zvemvura mafomu. Ichi chivakwa chakakosha muzvigadzirwa senge pendi, zvinonamatira, uye zvinhu zvega zvega.

4. Kunamatira uye kusunga:

• Cellulose ana ana anaita kuti avandudze kuderedza mumamiriro ezvinhu, achiwedzeredza zvivakwa zvinosunga. Izvi zvakakosha mukushandisa kunge Wallpaper paste, uko kushamwaridzana kunzvimbo dzakasiyana siyana kwakakosha.

5. Kuvhara kwekunetseka kwekudzikiswa:

• Mimwe mheremalo cellaulose vaitherya kugona kuderedza nzvimbo yekunetsana kwemvura mumvura-yakavakirwa mvura. Ichi chivakwa chinobatsira mukushandisa senge magetsi, uko kwakavandudzwa kunyorodza uye kupararira kunodiwa.

6. Thermal Glation:

• Mamwe mheremalolose eters oterbit thermal emagetsi. Izvi zvinoreva kuti ivo vanogona kuumba maGels kana kuremerwa kana vachipisa pasi pekupisa, kupa tembiricha-inotsamira viscossity kudzora mukugadzirisa.

7. Kugadzikana mumhinduro:

• Cellulose ana vana kazhinji vanoratidza kugadzikana kwakanaka mumhinduro, vachichengetedza zvivakwa zvavo nekufamba kwenguva. Uku kugadzikana kwakakosha pakuita kwenguva refu kwezvigadzirwa zvavanoshandiswa.

8. Kuenderana nezvimwe zvinoshandiswa:

• Cellulose ana vana vanoenderana neakasiyana-siyana ezvinyorwa zvinowanzoshandiswa mune zvekuumbwa, kusanganisira munyu, surfacts, uye vamwe polymers. Kuenderana uku kunobvumira kune zviitiko zvevedzimwe mumasango akasiyana siyana.

9. Biodegradability:

• Cellulose ana anaiters inotorwa kubva kune inovandudza zviwanikwa uye inoonekwa seyakavapo bioderable. Iyi mamiriro ekunze yakakoshesa mukushandisa iyo biodegradability is a kiyi yekufunga.

10. Kwete-chepfu uye akachengeteka:

11. PH Simba:

12. Pseudoplasticsity:

13. Kushivirira Munyu:

Izvo zvakakosha kuti zviitike kuti zvinhu zvakananga zve cellulose etana zvinogona kusiyana zvichienderana nerudzi rwechinguvana ether uye degree rayo rekutsiva. Vagadziri vanopa zvakadzama technical yehunyanzvi kune yega yega cellulose etera chigadzirwa, kubatsira mafomu ekugadzira sarudza zvakanyanyisa kusiyana kwakakodzera kune yavo chaiyo yekushandisa.
