Elona mpahla libalulekileyo leSoftware ye-Selesese i-Ether ipropathi yayo ye-rohemoe. Iipropathi ezikhethekileyo zeRhemolocal zeSelulose eSelethuase Eona zizenza zisetyenziswe ngokubanzi kwiindawo ezahlukeneyo, kwaye ukufundisisa iipropathi ze-RIology kuluncedo kuphuhliso lwemihlaba entsha yesicelo okanye ukuphuculwa kwezinye iindawo zesicelo. I-LI jing evela kwi-Shanghai Jiao Tonk yase-Tonk ye-Candelo lenkqubo ye-RHIOOOORTERTEREI-carboxeymethylcelose (cmc), kubandakanya nempembelelo yeeparamitha ze-CMC ze-CMC (ubunzima bemoyarcular kunye nenqanaba lokufakelwa), uxinaniso PH, kunye namandla e-Ionic. Iziphumo zophando zibonisa ukuba uqhawulo-mvume lwe-zero lonyuka ngokunyuka kobunzima bemolekyuli kunye nenqanaba lokufaka endaweni. Ukunyuka kobunzima bemolekyuli kuthetha ukukhula kwe-molecular thein, kwaye intelekelelo elula phakathi kweemolekyuli inyusa ukufakwa kwesisombululo; Umgangatho omkhulu wokufaka endaweni yenza iimolekyuli zizolula ngakumbi kwisisombululo. Urhulumente ukhona, ivolumu ye-hydrodynamic inkulu, kwaye i-vickosity iba sisikhulu. Uhlobo lwecombululo lweCMC AMAULYO OKUQHUTYWA NOKUKHUSELEKO OLUFANELEKILEYO, OYA KUDLULEKILE. UVenkile wesisombululo uyancipha ngexabiso le-pH, kwaye xa liphantsi kunexabiso elithile, i-viscosity inyuka kancinane, kwaye ekugqibeleni i-acid yasimahla yenziwa kwaye icacisiwe. I-CMC yi-polymer polymer, xa iyongeza ityuwa enesisu, i-ion, i-k + inkulu, i-vickosity iya kuncipha ngokufanelekileyo. Ukongezwa kwe-caz ye-caz edivation + kubangela ukumiswa kwesisombululo ukuncipha kuqala kwaye emva koko unyuke. Xa uxinzelelo lwe-ca2 + liphezulu kunendawo yesifuba, iimolekyuli ze-CMC inxibelelana ne-CA2 +, kunye nomsebenzi obekhona kwisisombululo. I-Liang yaqin, iYunivesithi yaseNyakatho yaseTshayina, njl. Iziphumo zophando zifumanise ukuba: (1) I-HydroxyEtheetheethyl sellulose ineendlela eziqhelekileyo zokuziphatha kumanzi acocekileyo, kwaye ukuncitshiswa kokuncitshiswa konyukayo. I-viscosity ye-intrinsic ye-chydroxythyl seluplose enenqanaba eliphezulu lokufaka endaweni ye-cudroxyyethyl ye-chydroxythl yeselcelote. . Kugxininiswa okuthile kwesisombululo setyuwa, ukubonakala okubonakalayo kwe-chec kunciphisa ukonyuka kwesongezwe ekongezweni. Ngaphantsi kwenqanaba le-Shoiar efanayo, ukubonakala okuqinisekileyo kwe-chec kwiNkqubo yeSisombululo seCacl2 iphakamile kakhulu kune-chec kwinkqubo yesisombululo se-NAACL.
Ngokwanda okuqhubekayo kophando kunye nokwandiswa okuqhubekayo kweendawo zokwenza isicelo, iipropathi zezisombululo zenkqubo ezixubileyo ezithathwe ziiSeleses ezahlukeneyo zeSelecelie yafumana ingqalelo yabantu. Umzekelo, i-Sodium Carboxymethyl Selelose (I-NACMC) kunye ne-HydroxyEtheetheethl seluplose (Hec) isetyenziswa njengeearhente ze-oyile ezihlangeneyo, kodwa ifuthe lokusebenzisa lodwa alilungile. Nangona yayikukuba yi-viskosity elungileyo, ichaphazeleka ngokulula kubushushu be-reservoir kunye netyuwa; Nangona le yokugqibela inobushushu obulungileyo kunye nokungaxhathisi ityuwa, amandla awo aqaqambileyo ahlutha kwaye umthamo mkhulu. Abaphandi baxube izisombululo ezibini kwaye bafumanisa ukuba uVeksity wesisombululo esiyintloko saya kukhulu, ukunganyange kobushushu kunye nokuxhathisa ityuwa kuphuculwe kwinqanaba elithile, kwaye iSiphumo seSicelo saphuculwa. I-vorica sovilj et al. Sele wafunda indlela yokuziphatha kakuhle kwesisombululo senkqubo yomxube equlunqwe nge-HPMC kunye ne-NACMC kunye ne-Aneion Surfloudment enombala ojikelezayo. Ukuziphatha kakuhle kwenkqubo yenkqubo kuxhomekeke kwi-HPMC-NCMC, i-HPMC-SDS kunye ne-NPMC- (i-HPMPMC- (i-HPMCMC) Iziphumo ezahlukeneyo zenzeka phakathi.
Ipropathi ye-RIOOOOS ye-EEE SELTOS SOSOSOSS SOSOSTS ikwachaphazeleka ngezinto ezahlukeneyo, ezinjengeongezelelo, amandla omatshini angaphandle kunye neqondo lobushushu. UThamyoki Hino et al. ifundwe impembelelo yokongezwa kweNicotine kwi-RIOTIONGERRTUSTER ye-Hydroxypropyl Methylceluplose. Kwi-25c kunye ne-querication engaphantsi kwe-3%, i-HPMC eboniswe neNewnia. Xa kwakongezwa i-nitine, i-viscofity yanda, eyathi i-nicotine yandise ilungelo lokungenaI-HPMCIimolekyuli. I-Nikotine apha ibonisa ifuthe lokutola iphakamisa i-gel point kunye nendawo ye-HPMC. Amandla omatshini anjengamandla eShear aya kuba nefuthe elithile kwipropathi ye-ithewose ether Atheeus. Usebenzisa i-rucimimer ye-rumological kunye nesixhobo esincinci sokutyibilikisa, sifunyaniswe ukuba kwisisombululo se-semi-dilute, ngenxa yokuxhuzula ishera, ngenxa yokuxutywa kwe-Shear, ubushushu be-FOG POP buya kunyuka.
