I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo ngoluhlu olubanzi lwezicelo kumashishini ahlukeneyo, kubandakanya amayeza, ukutya, ukwakhiwa kunye ne-cosmetics. Xa ujonga iipropathi zayo ze-thermal, kubalulekile ukuba ubeke ekuziphatheni kwayo malunga notshintsho lobushushu, uzinzo lobushushu, kunye nayiphi na into enxulumene noko.
Uzinzo lwe-shirm: i-HPMC ibonakalisa uzinzo lwe-thermal elungileyo kuluhlu lobushushu olubanzi. Ngokuqhelekileyo ibola kubushushu obuphakamileyo, ngokufuthi i-200 ° C, kuxhomekeke kubunzima bemolekyuli, isidanga sokufaka kunye nezinye izinto. Inkqubo yokonakaliswa ibandakanya ukucoceka kwe-selsebose yeselfowuni kunye nokukhutshwa kweemveliso zokungalunganga.
Iqondo lobushushu beglasi I-TG ye-HPMC iyahluka ngokuxhomekeke kwinqanaba layo lokufakwa endaweni, isisindo semolekyuli, kunye nomswakama. Ngokubanzi, i-IT isukela kwi-50 ° C ukuya kwi-190 ° C. Ngasentla i-TG, i-HPMC iba bhetyebhetye kwaye imiboniso eyandayo yokuhamba kwemolekyuli.
Inqaku lokunyibilika: I-HPMC ecocekileyo ayinayo indawo enyibilikayo yenyibilika kuba yipolymer ye-amormius. Nangona kunjalo, iqaqamba kwaye inokuhamba ngamaqondo obushushu aphakamileyo. Ubukho bezongezo okanye ukungcola kunokuchaphazela indlela yokudlala yayo.
Ukuqhutywa kwe-thermal: I-HPMC inengxaki yokuqhutywa komhlaba ephantsi xa kuthelekiswa neentsimbi kunye nezinye iipolimers. Le ndawo iyenza ifanelekile ukusetyenziswa kwezicelo ezifuna ukufudumala kwe-thermal, ezinje kwiitafile zamachiza okanye izinto zokwakha.
Ukwanda kwe-shirmal: Njengee-polymers ezininzi, i-HPMC yandiswa xa ishushu kwaye izivumelwano xa zipholile. Ukusebenza kolwandiso lwe-shirmal (i-CTE) ye-HPMC kuxhomekeke kwizinto ezifana nokuqulunqwa kweekhemikhali kunye neemeko zokulungisa. Ngokubanzi, ine-CTE kuluhlu lwe-100 ukuya kwi-300 PPM / ° C.
Umthamo wobushushu: Umthamo wobushushu we-HPMC uphoxwa yinto yayo yemolekyuli, inqanaba lokufaka endaweni, kunye nomswakama. Ngokwesiqhelo isusela kwi-1.5 ukuya kwi-2.5 j / g ° C. Iidigri eziphezulu zokufaka endaweni kunye nomswakama komswakama zihlala zinyusa amandla obushushu.
Ukonakaliswa kwe-thermal: Xa kutyhilwe amaqondo obushushu aphezulu ngamaxesha okuphezulu, i-HPMC inokwenza ukonakaliswa kwenkcitho. Le nkqubo inokubangela utshintsho kwisakhiwo sayo sekhemikhali, esikhokelela kwilahleko yepropathi efana nokufakwa kwe-viscofity kunye namandla oomatshini.
Ukuphuculwa kweMvumelwano ye-Hermal Merication: I-HPMC inokuguqulwa ukuphucula ukuqhutywa kwenkqubo ye-thermal yezinto ezithile. Ukubandakanya i-fillers okanye i-onsortives, ezinje ngamasuntswana okanye iikhabhoni zekhabhoni, unokuphucula iipropathi zokudluliselwa kobushushu, owenza ilungele izicelo zolawulo lobushushu.
Izicelo: Ukuqonda iipropathi ze-irmal ye-HPMC kubalulekile ukuze kusetyenziswe ukusetyenziswa kwazo kwizicelo ezahlukeneyo. Kwimigangatho yamayeza, isetyenziswa njenge-binder, ifilimu yangaphambili, kunye ne-arhente yokukhutshwa-khupha i-arhente yokukhutshwa kwetafile. Ngokwakha, kuqeshwa kwizixhobo ezisekwe kwizimbo zokuphucula ukusebenza, ukunamathela, kunye nokugcinwa kwamanzi. Ukutya kunye ne-cosmetics, isebenza njenge-thi chorner, i-stabilizer, kunye ne-mulssifier.
I-HydroxyPOpyl Methylcelceltulose ibonisa uluhlu lweepropathi ze-thermal eyenza ilungele izicelo ezahlukeneyo kumashishini ahlukeneyo. Uzinzo lwayo lobushushu, ubushushu benguqu yeglasi, ukuqhubela kwengqondo, kunye nezinye iimpawu zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kwawo kwiindawo ezithile nakwizicelo. Ukuqonda ezi mpahla kubalulekile ekusebenziseni kakuhle kwe-HPMC kwiimveliso kunye neenkqubo ezahlukeneyo.
