Isifundo sokuqala sokugcinwa kwamanzi amachiza eHydroxypropyl Methylcelcelce

Hydroxypropyl methylcelculose (hpmc)Ngaba i-polly ye-polymer ye-polymer yasetyenziswa ngokubanzi kwicandelo lolwakhiwo, amayeza, ukutya kunye nemveliso yekhemikhali. Umsebenzi wayo ofanelekileyo wokugcina amanzi wenza ukuba idlale indima ebalulekileyo kwizicelo ezininzi zemveliso.

I-HPMC yi-ionic ye-ionsulose ether efunyenwe ngokutshintsha kweekhemikhali ye-seluplose yendalo enjengokuthintela kunye nokuthengisa. Ngenxa yokusekwa kwayo kakuhle, ukwenza ifilimu, ukugcinwa kwamanzi kunye neepropathi ze-qubric, isetyenziswa ngokubanzi kwisamente, iingubo, amacwecwe echiza kunye namanye amasimi. Kwizinto zokwakha, umthamo wokugcina amanzi eKimocell®HPMC uchaphazela ngokuthe ngqo umsebenzi wokwakha kunye nokugqitywa kwemveliso yokusebenza, ngoko ke kubaluleke kakhulu ukufundisisa ngendlela yokugcina amanzi.

I-1. Ulwakhiwo lweMolekyuli kunye nendlela yokugcina amanzi ye-HPMC

I-skeleton esisiseko ye-HPMC yi-Selelulose, kwaye inxalenye yayo ye-hydroxyl ithathelwe indawo yi-hydroxylypropy ye-hydroxyl kunye ne-methyl, eyenza ukuba igcinwe kakuhle amanzi kunye nokugcinwa kwamanzi. Indlela yokugcina amanzi ye-HPMC ikakhulu ibandakanya le miba ilandelayo:

I-Hydrogen Bonding: I-HPMC Molecules iqukethe inani elikhulu lamaqela e-hydroxyl, enokwenza iimolethi ze-hydrogen ngeemolekyuli zamanzi, i-adsorb kwaye ichonge amanzi, ngaloo ndlela ukuphuculwa komthamo wokugcina amanzi.

Isiphumo sesisombululo: i-HPMC ivele emanzini ukwenza isisombululo se-viscofity ephezulu, enciphisa izinga lemilinganiselo yamanzi, licothisa ukuvela kwamanzi, kwaye kuphucula ukugcinwa kwamanzi kwenkqubo.

Isiphumo seGal: Isisombululo se-HPMC siya kufikelela kubushushu obuthile kubushushu obuthile ukwenza isakhiwo senethiwekhi, esinceda ukugcina amanzi.

I-2. IZINTO EBUCHULE UKUSETYENZISWA KOMSEBENZI WOKUGQIBELA KWE-HPMC

Umsebenzi wokugcinwa kwamanzi we-HPMC uchatshazelwa zizinto ezininzi, kubandakanya ubunzima bemolekyuli, isidanga sokufakwa endaweni, isisombululo sobuchule kunye nezinto zangaphandle zokusingqongileyo.

Ubunzima bemolekyuli: i-HPMC enemilinganiselo enkulu yemolekyuli inefuthe elinamandla lokugcina amanzi, kodwa ireyithi yokuchithelwa kwexabiso ihamba kancinci.

Isidanga sokufakwa endaweni: I-Mazantsi kunye ne-hydroxypropy ye-HPMC ichaphazela ukubenzela amanzi kunye nokugcinwa kwamanzi. Inqanaba elifanelekileyo lokufaka endaweni linceda ukuphucula ukusebenza kwalo lokugcina amanzi.

I-Sombulelo: Ukuphakathi kwe-HPMC, okukhulu isisombululo isisombululo, kunye nokukhulula isithintelo kumanzi ahlutha amanzi, ngaloo ndlela ukuphuculwa komsebenzi wokugcina amanzi.

Izinto zokusingqongileyo: Iimeko zangaphandle ezinje ngobushushu kunye nokufuma zibe nefuthe elibonakalayo kwifuthe lokugcina amanzi kwi-HPMC. Imeko yobushushu ephezulu inokukhawulezisa ukuphuma kwamanzi, kodwa i-thermalgert yejeli ye-HPMC inokuphelisa le mpembelelo ukuya kuthi ga.

I-3. Ukugcinwa kwamanzi kwi-HPMC kwimo eyahlukileyo yesicelo

Izinto zokwakha: Kwizixhobo zesamente esine-gyppum kunye ne-kimbacell®hpmc ngokukuko ukuphulukana namanzi ngokukhawuleza, ukuphucula ukusebenza, kunye nokwandisa amandla, kwaye unciphise amandla, kwaye unciphise amandla, kwaye unciphise amandla.

Amalungiselelo amachiza amayeza: kwiitafile zamachiza, i-HPMC inokusetyenziswa njengezinto zokukhutshwa ezinzileyo ukulawula izinga lokukhutshwa kwamanzi kunye nokuphucula uzinzo lwamayeza.

Umzi-mveliso wokutya: i-HPMC isetyenziswa njengendawo yokutya kunye ne-moisturizer yokuphucula incasa kunye nokulondolozwa kokutya.

Ngesakhiwo sayo esahlukileyo,I-HPMCUnoluhlu olubanzi lwexabiso lesicelo kwimimandla yokwakha, amayeza, ukutya, njl njl.
