I-HPMC (i-hydroxypropyl methyl seluplose) yi-selsulose esetyenzisiweyo esetyenziswa kakhulu esetyenziswa ngokubanzi kumasimi amaninzi amashishini, ngakumbi kulawulo lwe-viscosity kunye nezinto ezinamabala. Ngenxa yobume bayo obukhethekileyo kunye neepropathi zomzimba, i-HPMC inokuphucula i-viscofity, uzinzo kunye neepropathi zendaleko zeemveliso zemveliso. Ke ngoko, isetyenziswe ngokubanzi kwiingubo, zokwakha izinto, iziyobisi, iziyobisi, ukutya kunye namanye amasimi.
Iimpawu ezisisiseko ze-HPMC
I-HPMC yimpahla yePolymer eyenziwe kwi-cutose yendalo eguqulweyo. Ikhonkco layo le-molecular liqulathe amaqela e-hydrophilic kunye namaqela e-hydrophobic, ngoko inamandla amahle okuzola kwamanzi kunye nokuhambelana kwendalo. Inyibilikisa emanzini abandayo ukwenza isisombululo esibonakalayo okanye sokudumisa. Iimpawu eziphambili ze-HPMC zibandakanya:
Iipropathi ezihle kakhulu: I-HPMC inokunyusa kakhulu i-viscofity yezisombululo ngendlela ephantsi, ibonelela ngeziphumo eziphezulu zokuthambisa. Oku kwenza isithako esifanelekileyo kwiimveliso zemizi-mveliso njengokwakha izinto zokwakha kunye nekhredithi ukuphucula ukusebenza kwemveliso.
Ulawulo lwe-viscosity elungileyo: i-HPMC inokufikelela kulawulo lwe-viscofity echanekileyo ngokuhlengahlengisa ubunzima bayo kunye nesidanga sokufakwa endaweni (njengeeRhukulusi engenanto) ukuze uhlangatyezwane neemfuno zemo eyahlukileyo yesicelo. Umzekelo, kumzi-mveliso oqengqelekayo, i-HPMC ene-viscosis eyahlukileyo inokubonelela ngenqanaba elahlukileyo kunye nokusebenza kwengubo.
Uhlengahlengiso lwe-roheelogical egqwesileyo: Iipropathi ze-RIOOLOTER ze-HPMC zinokutshintsha ngotshintsho kwinqanaba le-Shear. Oku kuthetha ukuba xa i-static, yenza imeko ye-vikous eninzi, kwaye i-viscosity ihla ngemihla xa isetyenziselwa amandla okucheba (njengokuvuselela okanye ukutshiza), ukwenza ukuba imveliso ilula ukuyifaka. Phakathi kwezinto ezithile ezizezinye, ezi phawu lwe-HPMC zibaluleke kakhulu.
I-biocomatini elungileyo kunye netyhefu: i-HPMC isuselwa kwi-sellyulose yendalo, inetyhefu elungileyo, ayinatyhefu, ingacaphuki, kwaye ihlangabezana neemfuno zoKhuseleko lwezeNdalo. Ke ngoko, ineemfuno eziphezulu zokhuseleko kwi-cosmetics, iziyobisi, ukutya, njl njl. Ikwasetyenziswa ngokubanzi kwimimandla ephezulu.
Indlela yokuthambisa kwe-HPMC kwiimveliso zemizi-mveliso
Iipropathi ezinkulu ze-HPMC zibangelwa yindlela yayo yemolekyuli kunye nokunxibelelana kweemolekyuli kwisisombululo. Xa i-HPMC inyibilikisiwe emanzini okanye eminye imiqobo, imixokelelwane yayo ye-sucromolecular iya kuphinda ifumane kwaye yenze imikhosi eqinileyo ye-hydrogen kunye ne-van der imbonakalo yemolekyuli yeSolvent, ngaloo ndlela yandisa i-viscofity yenkqubo. Ukongeza, isakhiwo senethiwekhi esinemitha ezintathu ezenziweyo yi-HPMC kwisisombululo kukwayeyona nto iphambili kwintsebenzo yayo yokuthambisa. Imixokelelwane ye-molecular kwisisombululo se-HPMC ihambelana nokwakha ubume benethiwekhi, enciphisa ulwelo lwesisombululo kwaye ke ibonise i-viscofity ephezulu.
Kwimeko ezahlukeneyo zesicelo, i-viscosity ye-HPMC inokuhlengahlengiswa ngezi ndlela zilandelayo:
Uhlengahlengiso lobunzima bemolekyuli: i-viscosity ye-HPMC ihlala ihambelana nobunzima bemolekyuli. Ukukhululeka ubunzima bemolekyuli, ukuphakama kwe-viscosity yesisombululo. Ke ngoko, ngokukhetha iimveliso ze-HPMC ezinamatye ahlukeneyo eemolekyuli, izisombululo ezinokufunyanwa kwiimfuno ezahlukeneyo zokuhlangabezana neemveliso ezahlukeneyo zemizi-mveliso.
Ukulawulwa kwenqanaba lokufakwa endaweni: Isiphumo esihle se-HPMC sikwanxulumene ngokusondeleyo nesigaba salo sokufaka endaweni. Ukuphakama kwenqanaba lokufakwa endaweni, ukomelela kwe-hydrophility kunye nokubangcono isiphumo. Ngokulawula inqanaba lokufakwa endaweni ye-HPMC ye-HPMC kwaye amaqela e-hydroxypropy, iipropathi zayo zokubonisa zilawulwa ngokuchanekileyo.
Iziphumo ze-Constitotion yeSisombululo: Uxinzelelo lwe-HPMC ngesisombululo nako ukuchaphazela ngqo i-viscofity yayo. Ngokubanzi, ukugxininiswa okuphezulu kwesisombululo, kokukhona i-viscofity. Ke ngoko, ngokuhlengahlengisa uxinzelelo lwe-HPMC, ukulawulwa ngokuchanekileyo kwesisombululo sesisombululo kunokufezekiswa.
Iindawo zesicelo kunye neziphumo zokonwaba kwe-HPMC
Izinto zokwakha: I-HPMC ihlala isetyenziswa njenge-tickener kunye ne-vickosity yomlawuli kwizifakelo ezisekwe kwisamente, imikhono ye-tile, kunye nezixhobo zokuziqhelanisa nezinto zokwakha. Iziphumo zokonwaba kwayo kukhusela ukugcinwa kwamanzi kwezi zixhobo, kuphucula ukusebenza kwabo, kwaye kuthintela ukuqhekeza okanye i-shrinkige. Ingakumbi kumaqondo obushushu amaqondo obushushu, i-HPMC inokwandisa ixesha lokuvula lwezinto kwaye yandise uxanduva lwayo.
I-Coasthis kunye neepeyinti: Kwishishini lemali, i-HPMC isetyenziswa njenge-tickener kunye nearhente yokuphucula ukunamathela kwemali kunye nokuchasana ne-SAG ngexesha lokuqalisa. Kwangelo xesha, i-HPMC inokunceda ipeyinti ukugcina isabelo se-iyunifomu, thintela indawo yokuhlala ye-pigment, kwaye wenze ifilimu ehlekisayo kwaye iyunifomu ehlekisayo kunye neyunifomu yokuthambisa.
Iziyobisi kunye ne-cosmetics Iipropathi zayo ezilungileyo ezithandekayo zinceda ukuphucula uzinzo lwamachiza kwaye kwandise ixesha lesiphumo seziyobisi. Kwi-cosmetics, i-HPMC isetyenziswe ngokubanzi kwi-ichis, iikhrim, ii-copiratiors kunye nezinye iimveliso zokwandisa i-viscofity kunye nokuzinza kwemveliso ngelixa isetyenzisiwe.
Ishishini lokutya: I-HPMC isetyenziswa ngokusetyenziswa kwishishini lokutya njenge-thi chuker kunye nokuzinzisa, ngakumbi kwiimveliso zobisi, izicando, ii-jellies kunye neziselo. Iipropathi zayo ezingenatyhefu kwaye ezingenabungozi ziyenza iarhente ekhuselekileyo nenokuthenjwa ephucula ukuthungwa kunye nomlomo wokutya.
I-HPMC iye yaba yinto engenakuphikiswa imisebenzi engenakufumaneka kwiimveliso zanamhlanje zemizi-mveliso ngenxa yentsebenzo yayo ebalaseleyo yokusebenza kunye nokulawulwa kwe-viscosity. Ngokuhlengahlengisa ubunzima bayo, isidanga sokufana kunye nokusetyenziswa kwesisombululo, i-HPMC inokuhlangabezana neemfuno zokundwendwela iimveliso ezahlukeneyo zemizi-mveliso. Kwangelo xesha, izinto zayo ezingenabunzi, ezikhuselekileyo nezinobuhlobo zenze zasetyenziswa ngokubanzi ekutyeni, amayeza kunye nezixhobo kunye nezinye iinkalo. Kwixa elizayo, ngokuqhubela phambili phambili kwezenzululwazi netekhnoloji, imeko yesicelo ye-HPMC iya kuba nebanzi ngakumbi, kwaye izibonelelo zayo kulawulo lwe-Viscofity ziya kuphononongwa kwakhona kwaye zisetyenziswe.
