Ibakala lemihla ngemihla lemichiza ye-hydroxypropyl methyl cellulose

Ibakala lemihla ngemihla lemichiza ye-hydroxypropyl methyl cellulose yipolymer eyenziweyo elungiswe ngokuguqulwa kweekhemikhali zeselulosi yendalo njengemathiriyeli ekrwada.I-ether ye-cellulose iphuma kwi-cellulose yendalo, imveliso ye-cellulose ether kunye ne-polymer yokwenziwa yahlukile, eyona nto isisiseko yi-cellulose, i-polymer compound yendalo.Ngenxa yobungcali besakhiwo se-cellulose yendalo, i-cellulose ngokwayo ayinakukwazi ukusabela nge-etherifying agents.Nangona kunjalo, emva kokunyangwa kwe-ejenti yokudumba, iibhondi ze-hydrogen ezomeleleyo phakathi nangaphakathi kwamatyathanga emolekyuli ziyatshatyalaliswa, kwaye umsebenzi weqela le-hydroxyl ukhutshwa kwi-alkali cellulose enobuchule obusebenzayo.Emva kokusabela kwe-etherifying agent, i -OH iqela liguqulwa libe -OR iqela ukufumana i-ether cellulose.

Ibanga lemihla ngemihla lemichiza ekhethekileyo engama-200 amawaka e-viscosity ekhawulezayo i-hydroxypropyl methyl cellulose ngumgubo omhlophe okanye otyheli kancinane, kwaye awunavumba, awunancasa, awunatyhefu.Inyibilika kumxube wamanzi abandayo kunye nezinyibilikisi eziphilayo ukwenza isisombululo se-viscous esicacileyo.Isisombululo samanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinileyo, ukunyibilika kwamanzi akuchaphazeli i-pH.Ukuqina kunye nefuthe le-antifreeze kwi-shampoo kunye nokuhlamba umzimba, ukugcinwa kwamanzi kunye nokwakheka kakuhle kwefilimu yeenwele kunye nolusu.Ngokunyuka okukhulu kwezixhobo ezisisiseko, i-cellulose (i-antifreeze thickener) inokusetyenziswa kwishampu kunye nokuhlamba umzimba kunokunciphisa kakhulu iindleko kwaye kuzuze iziphumo ezifunwayo.

1. Iimpawu kunye noncedo lwemihla ngemihla ikhemikhali grade cellulose HPMC:

I-1, ukucaphuka okuphantsi, ukushisa okuphezulu kunye nesondo;

I-2, uluhlu olubanzi lwe-pH ukuzinza, kwixabiso le-pH le-3-11 uluhlu linokuqinisekisa ukuzinza kwalo;

3. Ukwandisa ugxininiso kwingqiqo;

4. Ukwandisa i-bubble, ukuzinzisa i-bubble, ukuphucula ukuvakalelwa kwesikhumba;

5. Ukuphucula ngokukuko amandla okuhlawula amatyala enkqubo.

2 imihla ngemihla ibakala lemichiza cellulose HPMC isicelo umda:

Isetyenziswa kwishampu, ukuhlamba umzimba, isicoci sobuso, i-lotion, i-cream, ijeli, i-toner, i-conditioner, iimveliso zokubumba, intlama yamazinyo, amanzi, amanzi okudlala.

3 Indima ye-HPMC yomgangatho wemichiza yemihla ngemihla:

Ekusetyenzisweni kwezithambiso, isetyenziselwa ukutyeba, ukugwebu, i-emulsification ezinzileyo, ukusasazwa, ukunamathela, ukwenziwa kwefilimu kunye nokuphuculwa kokugcinwa kwamanzi, iimveliso ze-viscosity ephezulu zisetyenziswa njengokujiya, iimveliso ze-viscosity ephantsi zisetyenziswa ikakhulu njengokunqunyanyiswa kunye nokwakhiwa kwefilimu. .

Itekhnoloji ye-HPMC yomgangatho wemichiza ye-4 yomgangatho we-cellulose:

I-Hydroxypropyl methyl fiber ukuziqhelanisa ne-viscosity yeshishini lemichiza ikakhulu i-100 lamawaka, i-150 lamawaka, i-200 lamawaka, ngokwefomula yabo yokukhetha inani elidityanisiweyo kwimveliso ngokubanzi isithathu ukuya kwamawaka amahlanu.
