Kubukhoboka obugqibeleleyo obugqibeleleyo, inani elongezelelekileyo le-hydroxypropyl methyl sellise i-HPMC iphantsi kakhulu, kodwa inokuyiphucula kakhulu intsebenzo yodaka olumanzi, olu lubaluleke kakhulu olwakhiwo. I-seluplose en-viscofity eyahlukileyo kwaye yeyangezwe inesiphumo esihle ekuphuculeni ukusebenza kodaka olwamileyo. Okwangoku, uninzi lwamanzi kunye nokufakelwa kwezifakiweyo kunezixhobo ezibi zamanzi, kunye nokwahlukana kwamanzi okwethutyana kwenzeka emva kwemizuzu embalwa yokuma. Ukugcinwa kwamanzi yintsebenzo ebaluleke kakhulu ye-methyl sether, kwaye kukwayindlela yokusebenza kwabantu abafakelweyo basekhaya, ngakumbi ezo ndawo zinamaqondo obushushu asezantsi, anikele ingqalelo. Izinto ezichaphazela ukusebenza kwamanzi kudaka olongezelelekileyo lwe-HPMC longezwe, i-viscosity ye-HPMC, ukulunga kwamasuntswana kunye neqondo lobushushu elisetyenziswa kulo.
I-1. Umxholo: I-Teluplose Ether yi-Synthetic Polymer ePhezulu esekwe kwi-selsulose yeNdalo ngokuguqula iikhemikhali. I-SelerUlose Ether yindawo yokukhutshwa kwendalo. Ukuveliswa kwe-ether yeselselose yahlukile kwi-polymers yokwenziwa. Eyona nto iphambili kuyo esisiseko yi-sellulose, i-polymer yendalo. Ngenxa yolwakhiwo olukhethekileyo lwe-seluplose yendalo, i-seluplose ge ayinasakhono sokusabela ngeearhente eziqinisekisiweyo. Kodwa emva kokuba iarhente yokudumba inyangwa, imibhobho eqinileyo ye-hydrogen phakathi kweemolekyuli kwaye ngaphakathi kwe-chain zitshatyalalisiwe, kwaye ukukhutshwa kweqela elisebenzayo kwi-Alkali Sekel. Emva kokuba i-arhente yokwakhiwa kwe-imeyile, iqela le-chie -oh liguqulwa kwiqela. Fumana i-sell sether. Uhlobo lwe-seluplose ether ixhomekeke kuhlobo, ubungakanani kunye nokuhanjiswa kwezinto. Ukwahlula-hlula kwe-Selese talsulose eTonis kukwasekelwa kwiindidi zokuthathela izinto, inqanaba lesiseko, ukonakala kunye nezicelo ezinxulumene noko. Ngokutsho kohlobo lokuthathela izinto kwi-molecular thein, inokwahlulwa ibe yi-monotere kunye ne-ether exubeneyo. I-HPMC sihlala sisebenzisa i-ether exutywe. I-HydroxyPOpyl Methyl Selel Iser HPMC yimveliso apho iqela leqela le-hydroxyl kwiCandelo lithathelwe indawo yeqela le-Fydroxypropy. I-HPMC isetyenziswa ikakhulu kwizinto zokwakha, i-Latex Ingubo, amayeza, i-chemistry yemihla ngemihla, isetyenziswa njengearhente ye-gickener, iarhente yokugcina amanzi, i-stailing, i-stander, kunye nearhente yefilimu.
2.Wayisela i-Telulose Ether: Kwimveliso yezinto zokwakha, ngakumbi i-Sete erys idlala indima engekhoyo, ngakumbi kwimveliso yodaka olukhethekileyo (uHlolo oluhlelweyo), lubalulekile. icandelo. Indima ebalulekileyo ye-Seley-inyibiliki ye-ether eseludaka ikakhulu kwiinkalo ezintathu. Inye imigudu yokugcina amanzi afanelekileyo, enye inempembelelo ekungangqiqweni kunye ne-ThixitRopy yodaka, kwaye owesithathu kukunxibelelana nesamente. Inkqubo yokugcina amanzi ye-selsulose ether ixhomekeke ekufungeni lwamanzi kwi-Cocier, ukwakhiwa kodaka, umthwalo wodaka, kunye nexesha lezinto ezibonakalayo. Ukugcinwa kwamanzi kwe-Selese I-Ertulose Ewe ivela ku-Solubase kwaye inomzimba onesithukuthezi e-Seleese uqobo.
I-thring kunye ne-Thiyotropy ye-Ether Sether: Indima yesibini ye-Telulose Ether-Stark ixhomekeke: Inqanaba le-Polymerization ixhomekeke: inqanaba le-polymering exhomekeke kwi-Telupelose Ethel, ukugxila kwesisombululo, ubushushu kunye nezinye iimeko. Ipropathi yokuhlutha yesisombululo ziimpawu ezizodwa ze-alkyl selliase kunye neziganeko zayo eziguqulweyo. Iimpawu zecandelo zihambelana nenqanaba lokufaka endaweni, isisombululo kunye nokongezwa.
Umthamo ofanelekileyo wokugcina amanzi wenza ukuba i-hydration igqitywe ngakumbi, inokuphucula ubugqwirha omanzi wodaka olumanzi, lunyusa amandla aphezulu kodaka, kwaye ixesha linokuhlengahlengiswa. Ukongezwa kwe-etelUlose Ether kwi-Traise Spraight Storser kunokuphucula ukutshiza okanye ukupeyinta komngxunya wodaka, kunye namandla olwakhiwo. Ke ngoko, i-Ethersese Ether isetyenziswa ngokubanzi njengesongezo elibalulekileyo kubukhoboka obuxubeneyo.
