Isiphumo sokuthambisaI-Selersese EtherKuxhomekeka kwi: Inqanaba le-polymerization ye-seluplose ether, isisombululo sesombululo, inqanaba le-Shear, iqondo lobushushu kunye nezinye iimeko. Ipropathi yegengi yesisombululo yahlukile kwi-alkyl sellulose kunye nokuguqulwa kwayo. Ipropathi yokurhafiswa ihambelana nenqanaba lokufaka endaweni, isisombululo kunye nokongezwa. I-HydroXlekyl Derivatives, iipropathi zejeli zikwahambelana nenqanaba lokuguqula kwe-hydroxayl. I-VICOSITY MC kunye ne-HPMC, i-HPMC, i-10% -15% ye-MC kunye ne-HPMMC inokulungiswa nge-5% -10% ye-MC kunye ne-HPMC inokulungiselela kuphela i-2% yesisombululo kuphela Ukuhlelwa kwe-viscofity ye-ether seluplose ikhutshelwe kunye ne-1% yesisombululo se-1%.
I-ethectur-moleculase-molecul-mollulose i-ertulose inesidima esinempumelelo kakhulu, kwaye i-polymers enemilinganiselo yemolekyuli eyahlukileyo inee-viscofis ezahlukeneyo kwisisombululo soxinaniso. UVenkile ekujoliswe kuyo unokufezekiswa kuphela ngokongeza isixa esikhulu se-moleculase esineselula. I-viscosity yayo ayinamsebenzi mncinci kwixabiso le-Shear, kwaye i-viscofity ephezulu ifikelela kwithagethi yethagethi, efuna ukongeza kancinci, kwaye i-vickosity ixhomekeke ekusebenzeni kakuhle. Ke ngoko, ukufezekisa ukungqinelana okuthile, isixa esithile se-ether sether (uxinzelelo lwesisombululo) kunye ne-vissosity yesisombululo kufuneka iqinisekiswe. Iqondo lobushushu le-gene lesisombululo likwancipha ngocoselelo ngokunyuka kwengxaki yesisombululo, kunye ne-gels kubushushu begumbi emva kokufikelela uxinzelelo oluthile. Ukugxininiswa kwe-HPMC iphakame kakhulu kubushushu begumbi.
Ukungqinelana kunokulungiswa ngokukhetha ubungakanani be-paulticle kwaye ukhethe iiselwase Ukulungiswa okubizwa ngokuba kukwazisa inqanaba elithile lokufakwa endaweni yamaqela e-hydroxaskyl kwisakhiwo seSkeleton ye-MC. Ngokutshintsha amaxabiso okufana nabantu ababini, oko kukuthi, i-DS kunye ne-DS kunye neMimandla yeMigangatho ye-Manages Iimfuneko ezahlukeneyo zomsebenzi we-Teluplose Ethely inokufunyanwa ngokutshintsha amaxabiso okuqala atshintshiwe kwezinto ezimbini.
Isisombululo se-vissosity se-ethe molous ye-etheeus atheeus i-ThixitRopy ephezulu, ekwangumlinganiswa omkhulu we-ether yeseluplose. Izisombululo ze-ACTEACE ze-MC Polymers zihlala zine-pseudoplastic kunye ne-non-th-th-th-th-thyropic fluity ngaphantsi kweqondo lokushisa layo, kodwa iNewtonian Sperties ngamaxabiso asezantsi asezantsi. I-pseudoplasticimostity inyuka ngobunzima bemolekyuli okanye uxinzelelo lwe-ether sether, ngaphandle kohlobo lokuthatha indawo kunye nenqanaba lokufaka endaweni. Ke ngoko, i-selupelose esuka kwiBanga le-viscosity efanayo, i-MC, i-HPMC, i-HMC, iya kuhlala ibonisa iipropathi ezifanayo ze-rheocical logama nje ukuba uxinzelelo kunye nobushushu zigcinwe rhoqo. I-Gels zesakhiwo isenziwa xa iqondo liphakanyisiwe, kwaye ihamba kakhulu i-Thixitropic. Uxinzelelo oluphezulu kunye ne-viscofity ephantsi yeselula i-Show Thrixotdropy naphantsi kweqondo lobushushu. Le ndawo yepropathi ixhamla kuhlengahlengiso lwenqanaba kunye nokungena ekwakhiweni kokwakha umdaka.
Kufuneka ichazwe apha ukuba iphezulu i-viscosity yeI-Selersese Ether, Kungcono ukugcinwa kwamanzi, kodwa okuphezulu kwe-viscofity, ukuphakama kwe-molecular moley ye-ether, kunye nokupheliswa okuhambelanayo ekuzenisweni, okunefuthe elibi kuxinzelelo lwe-Commarmas kunye nokuSebenza okubi. Ukuphakama kwe-viscofity, eyona nto icacileyo yokutyibilika kodaka, kodwa ayingqinelani ngokupheleleyo. Uhlobo oluthile oluPhakathi, oluPhakathi oluPhakamileyo, kodwa i-imeyile eguqulweyo i-Ether isebenza kakuhle ekuphuculeni amandla olwakhiwo lodaka lwamanzi. Ngokunyuka kwe-viscofity, ukugcinwa kwamanzi kwi-ether
