Ukuphuculwa kwezibuko kuneempembelelo ezahlukeneyo. Okwangoku, uninzi lwamanzi kunye nokufakelwa kwezinto ezingekhoyo kunendlela yokugcina amanzi, kwaye amanzi olwelo ayahlukanisa emva kwemizuzu embalwa yokuma. Ke kubaluleke kakhulu ukongeza i-Sell Sether ecekeceke.
Makhe sihlolisise ubuchule obunzima be-seluplose eterase ecemeni.
I-selsulose ether-ukugcinwa kwamanzi
Ukugcinwa kwamanzi yintsebenzo ebalulekileyo ye-methyl seler ither, kwaye kukwayindlela yokusebenza kwabantu abanodaka basekhaya, ngakumbi abo bakwimimandla esemazantsi ngamaqondo obushushu aphezulu, anikele ingqalelo.
Kwimveliso yezinto zokwakha, ngakumbi ipoder yodaka, i-Sether Ether idlala indima engenakufikelelwa, ngakumbi kwimveliso yodaka olukhethekileyo (udaka oluhleweyo), lubaluleke kakhulu kwaye lubalulekile.
I-viscosity, umthamo, ubushushu obunobushushu kunye nemo yemolekyuli ye-etelulose i-ether ineempembelelo enkulu ekusebenzeni kwayo amanzi. Phantsi kweemeko ezifanayo, kokukhona i-viscosity ye-selupelose ether, engcono ukugcinwa kwamanzi; Idosi ephezulu, eyona ilungileyo yokugcinwa kwamanzi. Ngokwesiqhelo, isixa esincinci se-ether eselsese sinokuluphucula kakhulu ukugcinwa kwamanzi. Xa idosi ifikelela kwiqondo lokugcina amanzi olonyukayo, imeko yeqondo lokugcina amanzi liyacothisa; Xa iqondo lobushushu liphuma, ukugcinwa kwamanzi kwe-tarculose ether kuhlala kuncipha, kodwa ezinye ii-selsulose eziguqulweyo zikwanokugcinwa okungcono kubenzi bokushisa amanzi; Iintsinga ezinamanqanaba asezantsi okufaka i-vegan vegan ineendlela ezingcono zokugcina amanzi.
Iqela le-hydroxyl kwi-selsulose ether molecule kunye ne-oxygen atom kwi-ethe phelelo lwe-ether iya kunxulumana ne-hidrogen bond, ngaloo ndlela idlala indima elungileyo ekugcinweni kwamanzi; Imolekyuli yamanzi kunye ne-Itelulose Etherular Chain kuvumela iimolekyuli zamanzi ukungena ngaphakathi kwe-secromoles ye-taceromolecular kwaye ixhomekeke ekugcinweni kwamanzi e-slantery; I-Selsulose Ether iphucula i-cemes entsha ihambisa iipropathi ze-riheoology, ubume beNethiwekhi yeNethiwekhi kunye noxinzelelo lwe-OSMOICS okanye iipropathi zefilimu zefilimu ze-ether yeselselose ethintela ukungafani kwamanzi.
I-SelesUlose Even - Ukuqina kunye neThixotdOpy
I-selsulose ether i-Ethew i-Eathers i-Earnes emanzi ngohlobo oluhle kakhulu, olunokunyusa kakhulu ubuchule obuphakathi phakathi kodaka olumanzi kunye nolusu olusisiseko lokwenza udaka. Isetyenziswe ngokubanzi kwi-Plaphu, i-Brick Boohs Eader kunye neNkqubo yokuThenga yangaphandle. Isiphumo sokuqaqamba kwe-ether eseSelese sinokwandisa amandla okulwa okuchasene nokuchasene nezinto ezixubeneyo, thintela ukulibaziseka kwezinto, kwaye kungasetyenziswa kwikhonkrithi ye-fible, kwaye kungasetyenziswa kwikhonkrithi.
Isiphumo sokuqaqamba kwe-ether yeselselose e-Setheges kwizixhobo ezisekwe kwi-viscosity yesisombululo se-Selese. Phantsi kweemeko ezifanayo, ukuphakama kwe-viscosity ye-Teluplose Ether, kungcono uVeksini oLungelelaniso olusekwe kwiSamente, kodwa ukuba i-viscosity iphezulu kakhulu, iya kuchaphazela i-fluids kwaye iyakuchaphazela i-strodis kwaye iyakubeka isikhunta (njengokunamathela kwi-faksing). Ukufakwa kwenqanaba lokuzimela kunye nokuzimela ikhonkrithi, nto leyo ifuna ulwelo oluphezulu, lifuna uVeksi ophantsi lwe-Teluplose Ether. Ukongeza, isiphumo esihlekisayo se-ether eseSelese, siya kwandisa iimfuno zamanzi ezinto ezisisiseko zesamente kunye nokukhulisa isivuno sodaka.
Isisombululo se-vissosity se-ethe molous ye-etheeus atheeus i-ThixitRopy ephezulu, ekwangumlinganiswa omkhulu we-ether yeseluplose. Izisombululo ze-ACTYL Selelise zihlala zine-pseudoplastic kunye ne-non-th-th-th-thyropic fluity ngaphantsi kweqondo lokushisa layo, kodwa bonisa iipropathi ze-Newtonian kwiindawo ezinamaxabiso asezantsi asezantsi. I-pseudoplasticimostity inyuka ngobunzima bemolekyuli okanye uxinzelelo lwe-ether sether, ngaphandle kohlobo lokuthatha indawo kunye nenqanaba lokufaka endaweni. Ke ngoko, iseluplose esuka kwiBanga le-viscosity efanayo, nokuba yeyiphi na i-MC, i-HPMC, i-HMC, iya kuhlala ibonisa iipropathi ze-rheeology enye okoko uguquko 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 ichongwe apha ukuba i-viscosity yeselsese i-ether, ilunge ngakumbi ekugcinweni kwamanzi, kodwa iphakamile i-vissosity ye-felulose ye-ether, kunye nefuthe elilinganayo kuxinzelelo lwe-Colmar.
I-Sersulose Ether-Isiphumo sokungena komoya
I-Teluplose Ether inomphumo ongenamsebenzi ongenamsebenzi wesamente. I-Teluplose Ether inee-hydrophilic zamaqela (amaqela e-hydroxyl, amaqela e-ERE) kunye namaqela e-hydrophobic (amaqela e-methyl, amakhonkco e-gethyl, amakhonkco e-glucose), kwaye ungumphumo womzimba, ngaloo ndlela enefuthe lomoya.
Isiphumo sokungenela i-Teluplose I-Ether iya kuvelisa isiphumo se- "Ibhola", enokuphucula ukusebenza kwezinto ezixubileyo ezixubileyo, njengokusasazeka kwepluri ngexesha lodaka; Iya kwandisa imveliso yodaka, inciphise iindleko zodaka; Kodwa iya kukhulisa ukutyeba kwezinto ezilukhuni kwaye inciphise iipropathi zayo zobuchwephesha ezinje ngamandla kunye namandla e-elastic.
Njenge-surticament, i-Selersese Ether ikwanomsebenzi omanzi okanye onyibilikayo kwii-clesments ezikhoyo, owonyusa ulwalamano lwezinto ezingenamsebenzi, kodwa isiphumo sayo sokungena simahla. Iziphumo zolwelo yindibaniselwano yokufaka iplastiki kunye neziphumo zokonwaba. Ngokubanzi, xa umxholo we-Teluplose Ether iphantsi kakhulu, ukusebenza okuphambili kukuncitshiswa kweplastiki okanye ukuncitshiswa kwamanzi; Xa umxholo uphakame, isiphumo esihle sokutshutshiswa kwe-seluplose enyuka ngokukhawuleza, kwaye ifuthe laso elingena moya lidla ngokugcwaliswa. Ke ibonisa njengesiphumo sokwahlula okanye ukwanda kwemfuno yamanzi.
I-Selersese Ether-Ukubuyiselwa
I-Teluplose Ether iyakwandisa ixesha lokuseta i-qumes, kwaye lilibazise ii-fitity kinetics zesamente, ephuculayo ukuphucula ububele, kodwa kunokubangela ukulibazisa inkqubela phambili yokwakha.
