Ucwaningo lokuqala ngokugcinwa kwamanzi kwamakhemikhali we-hydroxypropylllllm methylcellulose

I-Hydroxypropyl methylcellulose (HPMC)Ingabe impahla ene-polymer enencibilikayo esetshenziswa kabanzi emikhakheni yokwakha, umuthi, ukudla kwamakhemikhali kanye nemboni yamakhemikhali. Ukusebenza kwayo okuhle kakhulu kokugcina amanzi kwenza kube nendima ebalulekile ezihlolweni eziningi zezimboni.

I-HPMC iyi-ether engekho i-ether ether etholwe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo efana ne-alkalization kanye nokuthezeka. Ngenxa yokuqina kwayo okuhle, ukwakhiwa kwamafilimu, ukugcinwa kwamanzi kanye nokuthambisa okufuhlayo, kusetshenziswa kabanzi ku-cunmer udaka, izimbobo, amaphilisi wezokwelapha kanye nezinye izinkambu. Ezintweni zokwakha, umthamo wokugcina amanzi weKimacell®HPMC ngqo uthinta kahle ikhwalithi yokwakha nokusebenza komkhiqizo okuqediwe, ngakho-ke kubaluleke kakhulu ukutadisha indlela yayo yokugcina amanzi.

1. Isakhiwo samangqamuzana kanye nendlela yokugcinwa kwamanzi ye-HPMC

Isikhumba esiyisisekelo se-HPMC siyi-cellulose, futhi ingxenye yayo ye-hydroxyl ithathelwe indawo yi-hydroxypropyl kanye ne-methyl, okwenza kube ne-solubity enhle yokuhlaselwa kwamanzi nokugcinwa kwamanzi. Indlela yokugcina amanzi ye-HPMC ikakhulukazi ifaka phakathi kwezici ezilandelayo:

I-Hydrogen Bonding: Ama-molecule we-HPMC aqukethe inani elikhulu lamaqembu ama-hydroxyl, angakha ama-hydrogen bond ngama-molecule wamanzi, i-adsorb kanye nokugcina amanzi okugcinwa kwamanzi okuqukethwe.

Umphumela wokuqina kwesisombululo

I-GEL Effect: Isixazululo se-HPMC sizobhekana nokushisa okushisayo endaweni yokushisa ethile ukuze wakhe isakhiwo senethiwekhi, esiza ukugcina amanzi.

2. Izici ezithinta ukusebenza kokugcinwa kwamanzi kwe-HPMC

Ukusebenza kokugcinwa kwamanzi kwe-HPMC kuthintwa yizici eziningi, kufaka phakathi isisindo samangqamuzana, izinga lokufaka esikhundleni, ukugxilisa izixazululo nezici zemvelo zangaphandle.

Isisindo se-Molecular: I-HPMC ngesisindo esikhulu samangqamuzana inomphumela wokuqina onamandla, ngaleyo ndlela yenza ngcono umthamo wokugcina amanzi, kepha izinga lokuchithwa lihamba kancane.

I-degree yokufakwa esikhundleni Izinga elifanele lokufaka esikhundleni lisiza ukuthuthukisa ukusebenza kwalo kokugcina amanzi.

Ukuhlushwa kwesixazululo: Ukuphakamisa okuphezulu kwe-HPMC, kukhuphuka kakhulu isixazululo, futhi kukhudlwana izithiyo ezinkulu ekuphaphemeni kwamanzi, ngaleyo ndlela kuthuthukise umphumela wokugcinwa kwamanzi.

Izici zezemvelo: izimo zangaphandle ezifana nezinga lokushisa kanye nomswakama zinomthelela omkhulu ekutholeni indawo yokugcinwa kwamanzi ye-HPMC. Imvelo yokushisa ephezulu ingasheshisa ukuhwamuka kwamanzi, kepha izakhiwo ze-gel ezishisayo ze-HPMC zingadambisa lo mphumela ngezinga elithile.

I-3. Ukugcinwa kwamanzi kwe-HPMC kwizimo ezihlukile zohlelo lokusebenza

Izinto zokwakha: Ezintweni ezisuselwa kukhonkolo kanye nezinto zodaka ze-gypsum, i-kimacell®hpmc ingavimba ngempumelelo ukulahleka kwamanzi ngokushesha okukhulu, ngcono ukusebenza kokwakha, ukunciphisa imifantu, futhi kwandise amandla.

Amalungiselelo emithi emithi: Kumathebulethi wezemithi, i-HPMC ingasetshenziswa njengezinto zokukhishwa okuqhubekayo ukulawula isilinganiso sokukhishwa kwamanzi nokwenza ngcono ukuqina kwezidakamizwa.

Imboni yokudla: I-HPMC isetshenziswa njengomuntu omkhulu wokudla kanye ne-moisturizer ukwenza ngcono ukunambitheka nokulondolozwa kokudla.

Ngesakhiwo sayo samakhemikhali esiyingqayizivele,I-HPMCInenani elibanzi lesicelo emikhakheni yokwakha, umuthi, ukudla, njll. Ucwaningo lwesikhathi esizayo lungaphinde lusebenzise ukwakheka kwe-HPMC ukuthuthukisa ukusebenza kwalo kokugcina amanzi futhi wandise uhla lwayo lokugcina amanzi futhi wandise.
