zazise
I-Selessulose eves zii-anionyic zamanzi asuka emanzini athathwe kwi-seluplose. Ezi polymers zinezicelo ezininzi kumashishini ahlukeneyo njengokutya, amayeza, amayeza, kunye nolwakhiwo ngenxa yepropathi yazo efana nokutyibilika kwefilimu, nokwenza ifilimu, kunye nokuqiniswa kwevidiyo, nokuxhasa ifilimu, nokwenza oko. Enye yezona ndawo zibalulekileyo zeselsulose ethsen ngamaqondo obushushu awo (TG), iqondo lobushushu apho i-polymer apho i-polymer isebenza khona i-SOS kwi-SOS. Le ndawo ibaluleke kakhulu ekumiseleni ukusebenza kwe-seluplose even kwizicelo ezahlukeneyo. Kweli nqaku, sixoxa ngeqondo lokuhlaselwa kwe-thermal ye-HydroxyPOpyl MethylcelceLcelose (i-HPMC), yenye yezona zisetyenziswayo zeselfowuni esetyenziswayo kwishishini.
Iqondo lokuhlanjwa kwe-HPMC
I-HPMC yi-Semi-synthetic ye-selupeculase i-Etely isetyenziswe ngokubanzi kwizicelo ezahlukeneyo ngenxa yepropathi eyahlukileyo. I-HPMC inyibilika emanzini, yenza isisombululo esicacileyo se-viscous ngendlela ephantsi. Kwiimeko eziphezulu, i-HPMC yee-gells eziguqukayo xa zishushu kwaye zipholise. Ukuhla kwe-HPMC ye-HPMC yinkqubo yamanyathelo amabini abandakanya ukumiselwa kweeMielles ezilandelwa ngokudityaniswa kwee-milines ukwenza inethiwekhi yejeyi (umzobo 1).
Ubushushu be-HPMC ye-HPMC buxhomekeke kwizinto ezininzi ezinje ngenqanaba lokufakwa endaweni (DS), ubunzima bemolekyuli, uxinzelelo kunye ne-PH yesisombululo. Ngokubanzi, ukuphakama kwe-DS kunye nobunzima bemolekyuli ye-HPMC, iqondo lobushushu be-thermal. Ukuxinezeleka kwe-HPMC kwi-SPMC kuchaphazela i-TG, ukuphakama okuphezulu, ukuphakama kwe-TG. I-PH yesisombululo ikwachaphazela i-TG, kunye nezisombululo ze-acidic ezikhokelela kwi-TG esezantsi.
Ukuhlaselwa kwe-HPMC ye-HPMC kuyaphindiswa kwaye kunokuchaphazeleka kwizinto ezahlukeneyo zangaphandle ezinjengamandla e-Shear, ubushushu, kunye netyuwa. I-Shear iqhekeza ubume bejeli kwaye iphantsi i-TG, ngelixa ishushu ibangela ijeli inyibilike kwaye ithole i-TG. Ukongeza ityiwa kwisisombululo kuchaphazela i-TG, kunye nobukho beendawo ezifana ne-calcium kunye ne-magnesium yonyusa i-TG.
Ukusetyenziswa kwe-HPMC eyahlukeneyo
Ukuziphatha kwe-thermogerage kunokulungelelaniswa ngezicelo ezahlukeneyo. Ii-HPMCs ezisezantsi ze-TG zisetyenziswa kwizicelo ezifuna ukuhla kwe-gesid, ezinje nge dessert kwangoko, i-sauce kunye neSopp. I-HPMC ene-TG ephezulu isetyenziswa kwizicelo ezifuna ukulibazisa okanye ukubhekiswa kwexesha elide, njengokuqulunqwa kweenkqubo zokuhambisa iziyobisi, iitafile zokukhuthaza iitafile, kunye nokunxiba.
Kushishino lokutya, i-HPMC isetyenziswa njenge-thi checker, i-stabilizer kunye nearhente yeGeling. I-TG ye-TG ye-TG isetyenziswa kwifomu ye-dessert yethutyana efuna ukuhla kwe-gefid ukubonelela ngolungelelwaniso olufunwayo kunye nomlomo. I-HPMC ene-TG ephezulu isetyenziselwa ukusasazeka kwamafutha asezantsi apho ukulibaziseka okanye ukuhluthwa ixesha elide kunqwenele ukuthintela i-syneresis kunye nokugcina isasaza.
Kumzi-mveliso wamachiza, i-HPMC isetyenziswa njenge-binder, i-irintedgranti kunye ne-Arhente yokukhutshwa kwe-inter I-HPMC ene-TG ephezulu isetyenziswa ekuqulunqweni kweetafile zokukhutshwa kwandiselweyo, apho kulibazisayo okanye ukudalwa kwexesha elide kuyafuneka ukukhupha ichiza ixesha elide. I-TG ye-TG ye-TG isetyenziswa ekuqulunqweni kweetafile zomlomo, apho ukwahlukana ngokukhawuleza kunye nokuhlutha kuyafuneka ukubonelela ngomlomo kunye nokukhululeka kokuginya.
ukuququmbela
Ubushushu be-HPMC ye-HPMC yipropathi ephambili echaza indlela aziphatha ngayo kwizicelo ezahlukeneyo. I-HPMC inokutshintsha i-TG yayo ngokusebenzisa inqanaba lokufakwa endaweni, ubunzima bomzimba, uxinzelelo kunye nexabiso le-ps lesisombululo ukuze zilungele izicelo ezahlukeneyo. I-HPMC ene-TG esezantsi isetyenziselwa izicelo ezifuna ukuhlutha ngokukhawuleza, ngelixa i-HPMC ene-TG ephezulu isetyenziselwa izicelo ezifuna ukulibazisa okanye ukuhlutha ixesha elide. I-HPMC yindawo eguquguqukayo kunye nokuguqulela i-ether edibeneyo kwizicelo ezininzi ezinokubakho kumashishini ahlukeneyo.
