Kemikali ojoojumọ pataki hydroxypropyl methylcellulose!

Omi tutu ese hydroxypropyl methylcellulose (HPMC) English Name: Hydroxypropyl methyl cellulose (HPMC) Awọn inagijẹ ti o wọpọ: thickener ese, thickener idurosinsin, emulsion stabilizer, disperssion thickener, antifreeze thickener, Lẹsẹkẹsẹ cellulose.

Awọn paati akọkọ ati ilana kemikali: ether cellulose ti kii ṣe ionic ti a ṣe lati inu cellulose polymer adayeba.

Iṣafihan Ọja: Chuangyao Hydroxypropyl Methyl Cellulose (HPMC) jẹ polima ti kii-ionic, ether cellulose ti kii ṣe ionic ti a ṣe lati inu ohun elo polima adayeba ti cellulose. Ọja naa jẹ alaiwu, ti ko ni itọwo, lulú awọ ti ara ẹni ti kii ṣe majele, eyiti o le tuka ninu omi tutu lati ṣe ojutu viscous ti o han gbangba pẹlu didan, mimu, pipinka, emulsifying, ṣiṣẹda fiimu, suspending, adsorbing, gelling, and dada ti nṣiṣe lọwọ , Idaduro ọrinrin ati awọn ohun-ini colloid aabo.

Ipele kemikali ojoojumọ lẹsẹkẹsẹ hydroxypropyl methylcellulose HPMC jẹ lilo ni pataki ninu awọn kemikali asọ, awọn ọja mimọ kemikali ojoojumọ, awọn ohun ikunra ati awọn aaye miiran; gẹgẹbi shampulu, fifọ ara, fifọ oju, ipara, ipara, gel, toner, itọju awọ ara Irun kondisona, awọn ọja iselona, ​​toothpaste, itọ, omi ti nkuta isere, ati bẹbẹ lọ.

Awọn abuda ọja ti ipele kemikali lojumọ lẹsẹkẹsẹ hydroxypropyl methylcellulose HPMC:

1. Awọn ohun elo aise adayeba, irritation kekere, iṣẹ kekere, ailewu ati aabo ayika;

2. Omi solubility ati ohun-ini ti o nipọn: o le wa ni tituka ni omi tutu, tituka ni diẹ ninu awọn ohun elo ti o wa ni erupẹ ati idapọ ti omi ati awọn ohun elo ti o ni imọran;

3. Sisanra ati viscosity-npo: ilosoke kekere kan yoo ṣe itusilẹ viscous ti o han gbangba lẹhin itusilẹ, iṣipaya giga, iṣẹ iduroṣinṣin, awọn iyipada solubility pẹlu viscosity, isalẹ viscosity, ti o tobi ni solubility; ni imunadoko mu iduroṣinṣin sisan ti eto naa;

4. Iyọ resistance: HPMC ni a ti kii-ionic polima, jo idurosinsin ni olomi solusan ti irin iyọ tabi Organic electrolytes;

5. Iṣẹ-ṣiṣe oju-aye: ojutu olomi ti ọja naa ni iṣẹ-ṣiṣe dada, o si ni awọn iṣẹ ati awọn ohun-ini ti emulsification, colloid aabo ati iduroṣinṣin ibatan; ẹdọfu dada jẹ: 2% ojutu olomi jẹ 42 ~ 56dyn / cm;

6. PH iduroṣinṣin: iki ti ojutu olomi jẹ iduroṣinṣin laarin ibiti PH3.0-11.0;

7. Ipa idaduro omi: ohun-ini hydrophilic ti HPMC ni a le fi kun si slurry, lẹẹ ati awọn ọja pasty lati ṣetọju ipa-idaduro omi giga;

8. Thermal gelation: Nigbati awọn olomi ojutu ti wa ni kikan si kan awọn iwọn otutu, o di akomo titi ti o fọọmu a (poly) flocculation ipinle, ki ojutu npadanu iki. Ṣugbọn lẹhin itutu agbaiye, yoo yipada si ipo ojutu atilẹba lẹẹkansi. Iwọn otutu ninu eyiti iṣẹlẹ gel waye da lori iru ọja, ifọkansi ti ojutu ati oṣuwọn alapapo;

9. Awọn abuda miiran: awọn ohun-ini iṣelọpọ fiimu ti o dara julọ, bakannaa jakejado ibiti o ti ni resistance enzymu, dispersibility ati isomọra;

10. Ibẹrẹ akoko iki ti kemikali ojoojumọ hydroxypropyl methylcellulose ni omi tẹ ni kia kia ni iwọn otutu deede jẹ iṣẹju 3, ati pe akoko ibẹrẹ iki ni omi mimọ yoo lọra, nipa awọn iṣẹju 30, nitorinaa akoko iṣẹ to to, rọrun lati ṣakoso viscosity , rọrun lati lo.
