I-Selessulose ebhaka i-sellue luhlobo lwe-orlmeric Polymer Poinds iguqulwe ngokucothayo kwi-seluplose yendalo. Ziqhelekile kwizinto zokwakha, ngakumbi kwizixhobo ezisekwe kwimo yesamente. Impembelelo ye-Ether Sether kwi-Teluped kwiNkqubo yokuHlawula ikakhulu iboniswa ikakhulu kule miba ilandelayo: Ukusasazwa kwamasuntswana kwamanzi, isiphumo se-cenphology, kunye nokuphuhliswa kwamandla e-quance shydrations.
1. Intshayelelo
Inkqubo ye-hydration yesamente luluhlu lwezinto ezintsonkothileyo ngokwasemzimbeni kunye nekhemikhali phakathi kwesamente kunye namanzi. Oku kuphendula kubangela ukuba isamente icocwe ngokuthe ngcembe ukwenza isakhiwo esiqinileyo, ekugqibeleni ukuvelisa iimveliso ze-hydimes ezifana ne-calcium hydrate (csh) kunye ne-calcium hydroxide (Ch). Ngeli xesha le nkqubo, inqanaba lokuphendula lomlongo wesamente, ulwelo kunye nokugcinwa kwamanzi kunye nokugcinwa kwamanzi kwi-slicry, kunye nokwenziwa kweemveliso ze-hydration kuchaphazela ngqo amandla kunye nokuqina kwekhonkrithi yekhonkrithi.
2. Inyathelo lesenzo seSeluplose
Indima yesellulose idlala indima ebalulekileyo yomzimba kunye nekhemikhali yenkqubo ye-qumedy. I-Seley Sethel ichaphazela ikakhulu inkqubo ye-qumed ngeendlela ezimbini: enye kukuchaphazela ukusasazwa kunye nokuphuma kwamanzi kwi-cerry; Okunye kukuchaphazela ukusasazeka kunye nokuhla kwe-subsoclessus.
Ukulawula umswakama kunye nokugcinwa kwamanzi
I-Selerise i-Seuni zinokuphucula kakhulu ukugcinwa kwamanzi kwezinto ezisekwe. Ngenxa ye-hydrophicity eyomeleleyo, i-seluplose i-Ether inokwenza isisombululo esizinzileyo emanzini, esinokufumana nokugcina umswakama. Esi sibonelelo sokubamba samanzi kubalulekile ekunciphiseni izicwisiweyo ezibangelwe kukuphulukana namanzi ngokukhawuleza kwikhonkrithi ngexesha lokuhamba kwexesha. Ingakumbi kwiimeko ezomileyo okanye iimeko zokwakha amaqondo obushushu, i-Selesese I-Ether inokuthintela ngokufanelekileyo amanzi ekuphumezeni ngokukhawuleza kwaye aqinisekise ukuba isixa samanzi esimenqwa anele ukuxhasa impendulo yomhlukumelo.
I-RUOOLOLOGY NOKUFUNDA
I-Selerise ethen inokuphucula i-RUOOOOOOOOOOOOOOLOOLOGRE yesamente ityhila. Emva kokongeza i-Selersese Ether, ukungqinelana kwesamente i-slidery kuya kwanda kakhulu. Le phenomeno ichazwa ikakhulu kwisakhiwo se-chain ende eyenziweyo yi-selsulose ether molekyuli emanzini. Le molekyuli ende ende inokubuthintela intshukumo yamasuntswana yesamente, ngaloo ndlela yandisa ukubonwa kunye nokungqinelana kwesilayidi. Le ndawo ibaluleke ngokukhethekileyo kwizicelo ezifana nokuhlambela kunye neefowuni, njengoko zithintela udaka lokuhamba ngokukhawuleza ngelixa lusebenza ngokukhawuleza xa ubonelela ngokusebenza okukhulu.
Ukulibazisa i-hydration kunye nokulungelelanisa ixesha
I-Telupelose Ether inokulibazisa indlela yokusebenza ye-cememes kwaye yonyuse indawo yokuqala kunye nokusetshwa kwexesha lokugqibela lesamente. Oku kwenzeka kuba iimolekyuli ze-ertulose i-ertulose i-ersed i-arthed kumphezulu wesamente, ukwenza umqobo othintela unxibelelwano oluthe ngqo phakathi kwamanzi kunye nesamente, ngaloo ndlela ethoba i-hydrations yokuphendula. Ngokulibaziseka ukubeka ixesha, i-seluplose enene inokuphucula ukwenziwa kokwakha, ukunika abasebenzi bokwakha ixesha elingakumbi lokwenza uhlengahlengiso kunye nolungiso.
3. Impembelelo kuhlobo lweemveliso ze-hydration
Ubukho be-seluplose echwase echaphazela ubume bemveliso ye-ceng hydication. Izifundo zibonakalise ukuba i-morphology ye-calcoum hydrate (csh) ijeli iya kutshintsha emva kongeza i-selsese. I-seluplose i-ether Molekyule zinokuchaphazela ubume bekristali ye-CSH, iyenza ikhulule ngakumbi. Esi sakhiwo sikhululekileyo sinokunciphisa amandla kwangoko, kodwa ikwanceda ukuphucula ubunzima bezinto ezibonakalayo.
I-Selerise ethen inokunciphisa ukwakhiwa kwe-ettriririte ngexesha lenkqubo ye-hydrate. Kuba i-Seruplose Ether igcina izinga lokusabela kwe-hydration, inqanaba lokwenza i-ettrierite kwisamente lincitshisiwe, ngaloo ndlela kuncitshiswa uxinzelelo lwangaphakathi olubangelwa kukwandiswa kwequmrhu ngexesha lokunyanga.
4. Impembelelo kuPhuculo lweMandla
I-Seleose Teluplose ineempembelelo ezibonakalayo kumandla ophuculo lwezixhobo ezisekwe kwimo yesamente. Ngenxa yokuba i-seluplose eabo ibuyisa i-hydration yenqanaba lesamente, ukuphuculwa kwamandla okuqala kwesamente kuya kuhlala kuhamba kancinci. Nangona kunjalo, njengoko impendulo ye-hydration ye-Ether i-Sersulose Other Ands kunye neMveliso ye-Hydration I-Morphology inokuphuma ngokuthe ngcembe, eya kuthi incede ukuphucula amandla emva kwexesha elizayo.
Kuya kufuneka kuqatshelwe ukuba imali eyongeziweyo kunye nohlobo lwe-ether ese seluplose inefuthe elincinci lamandla. Isixa esifanelekileyo se-selsulose estulose sinokuphucula ukusebenza nokwanda kwamandla amathathu, kodwa ukusetyenziswa kakhulu kunokukhokelela ekuncipheni kwezinto ezisisiseko zesamente kwaye zichaphazele iipropathi zomsebenzi wokugqibela. Ke ngoko, kwizicelo ezenziwayo, uhlobo kunye nomphumo we-seluplose ether kufuneka ufaneleke kwaye zenziwe ngokweemfuno zobunjineli.
I-Selsulose Ether ichaphazela inkqubo ye-hydration kunye neepropathi zesamente ngokuphucula ukugcinwa kwamanzi kwezinto ezisekwe ngamanzi, ukuhlengahlengisa i-hydimetionrey, kwaye ichaphazele uhlobo lweemveliso ze-hydime. Nangona i-Seleswese inokubangela ukuphulukana namandla angaphambili, banokuphucula ukuqina kunye nobunzima bekhonkrithi kwixesha elide. Ukongezwa kwe-ETE Selesese I-Ete Inokuphucula kakhulu ukusebenza, ngakumbi kwimeko yesicelo efuna amaxesha abekiweyo kunye neemfuno eziphezulu zokugcina amanzi. Inezibonelelo ezingenakufikelelwa. Kwizicelo zokwenyani zobunjineli, ukhetho olufanelekileyo lohlobo kunye nedosi ye-ilese ye-selselose inokulinganisa amandla, ukusebenza kunye neemfuno zomoya.
