Uyini umehluko phakathi kwe-hydroxypropyllylylylylk methyl cellulose ne-methyl cellulose?

1.(HPMC) Izakhiwo Zomzimba Nezamakhemikhali:

1. Ukubukeka: I-MC imhlophe noma i-aff-white fibrous noma i-powder emhlophe, ye-odorless.

2 Ukuhlakazeka ngokushesha futhi kuvuvukala emanzini ashisayo ku-80 ~ 90 ° C, bese uncibilikisa ngokushesha ngemuva kokupholisa phansi. Isixazululo samanzi sizinzile kakhulu emazingeni okushisa asekamelweni, futhi singakwazi ukufundela okuphezulu, futhi ijeli lingashintsha nesixazululo ngokushisa. Inokukhula okuhle kakhulu, ukungafani, ukunamathela, ukuqina, ukuqina, ukugcinwa kwamanzi kanye nezakhiwo ezenziwe ngamafilimu, nokungapheli. Ifilimu eyakhekayo inobunzima obuhle kakhulu, ukuguquguquka nokusobala. Ngoba akuyona i-ionic, ingahambisana namanye ama-emulsifers, kepha kulula ukuphelelwa usawoti, futhi isixazululo sizinzile ngaphakathi kwe-PH2-12.

I-3. I-Afflent Density: 0.30-0.70g / CM³, CM³, Mayelana ne-1.3G / CM³.

2. Indlela yokuqeda:

Lapho imikhiqizo ye-MC inezelwa ngqo emanzini, izohlala bese ichithwa, kepha ukuchithwa kuhamba kancane futhi kunzima. Kunezindlela ezintathu zokuqothula eziphakanyisiwe ngezansi, futhi abasebenzisi bangakhetha indlela elula kakhulu ngokuya ngokusetshenziswa kwabo:

1. Indlela Eshisayo Yamanzi: Njengoba i-MC ayincibiliki emanzini ashisayo, i-MC ingahlakazeka ngokulinganayo emanzini ashisayo esiteji sokuqala, bese kuthi lapho sekupholile, izindlela ezimbili ezijwayelekile zichazwa ngale ndlela elandelayo:

1). Faka inani elidingekayo lamanzi ashisayo esitsheni bese usishisa cishe ku-70 ° C. I-MC yangezwa kancane kancane ngaphansi kokuvuselelwa kancane, ekuqaleni i-MC yantanta ebusweni bamanzi, bese kancane kancane yakha kancane kancane, eyayipholile ngaphansi kokuvusa.

2). Faka u-1/3 noma 2/3 wenani elidingekayo lamanzi esitsheni, bese usishisa ku-70 ° C. Ngokwendlela ka-1), hlakaza i-MC ukulungiselela ama-slurry amanzi ashisayo; Ngemuva kwalokho engeza inani elisele lamanzi abandayo noma amanzi eqhwa kumanzi ashisayo, ingxube ipholile ngemuva kokuvusa.

I-3. Indlela ye-Organic Solvent ye-Organic: isatshalaliswe ngaphambili noma i-WET MC enama-organic solvents, njenge-ethanol, i-ethylene glycol noma uwoyela, bese wengeza namanzi ukuze uncibilike, khona-ke i-MC nayo ingachithwa kahle ngalesi sikhathi.

3. Sebenzisa:

Lo mkhiqizo usetshenziswa kabanzi ekwakheni ukwakhiwa, izinto zokwakha, izimbobo ezihlakazekile, ama-papermerizall aids, ama-ejenti agcina amanzi, asetshenziswa i-ejenti yokunamathela, njenge-ejenti yokwakha I-Agent kanye nesikhumuli embonini ye-coating, futhi isetshenziswa kabanzi ekuvuthweni kwama-petroleum kanye nezimboni zamakhemikhali zansuku zonke.

I-methylcellulose (MC) Izakhiwo Zomzimba Nezinto Zamakhemikhali:

1. Ukubukeka: I-MC imhlophe noma i-aff-white fibrous noma i-powder emhlophe, ye-odorless.

2 Ukusabalalisa ngokushesha futhi kuvuvukala emanzini ashisayo ku-80 ~ 90> ℃, futhi kuncibilika ngokushesha ngemuva kokupholisa phansi. Isixazululo samanzi sizinzile kakhulu emazingeni okushisa asekamelweni, futhi singakwazi ukufundela okuphezulu, futhi ijeli lingashintsha nesixazululo ngokushisa. Inokukhula okuhle kakhulu, ukungafani, ukunamathela, ukuqina, ukuqina, ukugcinwa kwamanzi kanye nezakhiwo ezenziwe ngamafilimu, nokungapheli. Ifilimu eyakhekayo inobunzima obuhle kakhulu, ukuguquguquka nokusobala. Ngoba akuyona i-ionic, ingahambisana namanye ama-emulsifers, kepha kulula ukuphelelwa usawoti, futhi isixazululo sizinzile ngaphakathi kwe-PH2-12.

I-3. I-Afflent Density: 0.30-0.70g / CM³, CM³, Mayelana ne-1.3G / CM³.

4. Indlela yokuqothula:

I-MC> Lapho umkhiqizo ungezwe ngqo emanzini, uzobamba bese uncibilika, kepha ukuchithwa kuhamba kancane futhi kunzima. Kunezindlela ezintathu zokuqothula eziphakanyisiwe ngezansi, futhi abasebenzisi bangakhetha indlela elula kakhulu ngokuya ngokusetshenziswa kwabo:

1. Indlela Eshisayo Yamanzi: Njengoba i-MC ayincibiliki emanzini ashisayo, i-MC ingahlakazeka ngokulinganayo emanzini ashisayo esiteji sokuqala, bese kuthi lapho sekupholile, izindlela ezimbili ezijwayelekile zichazwa ngale ndlela elandelayo:

2). Faka u-1/3 noma 2/3 wenani elidingekayo lamanzi esitsheni, bese usishisa ku-70 ° C. Ngokwendlela ka-1), hlakaza i-MC ukulungiselela ama-slurry amanzi ashisayo; Ngemuva kwalokho engeza inani elisele lamanzi abandayo noma amanzi eqhwa kumanzi ashisayo, ingxube ipholile ngemuva kokuvusa.

I-3. Indlela ye-Organic Solvent ye-Organic: isatshalaliswe ngaphambili noma i-WET MC enama-organic solvents, njenge-ethanol, i-ethylene glycol noma uwoyela, bese wengeza namanzi ukuze uncibilike, khona-ke i-MC nayo ingachithwa kahle ngalesi sikhathi.

5. Sebenzisa:

Lo mkhiqizo usetshenziswa kabanzi ekwakheni ukwakhiwa, izinto zokwakha, izimbobo ezihlakazekile, ama-papermerizall aids, ama-ejenti agcina amanzi, asetshenziswa i-ejenti yokunamathela, njenge-ejenti yokwakha I-Agent kanye nesikhumuli embonini ye-coating, futhi isetshenziswa kabanzi ekuvuthweni kwama-petroleum kanye nezimboni zamakhemikhali zansuku zonke.
