Ulwakhiwo lwe-Selese

Izakhiwo eziqhelekileyo zeZibiniI-seluplosezinikwe ngemifanekiso 1.1 kunye ne-1.2. Idiliya ye-β-d-de-defrayim ye-molecule

Iyunithi yeswekile (iyunithi ephindaphindayo yeselselose) ithenjwe kwiqela elinye le-Ether nganye kwi-C (2), c (3) kunye ne-C (ie ukuya kuthi ga kwi-3

iqela le-ether. Ngenxa yobukho bamaqela e-hydroxyl, i-sellulose macromolecules ineebhondi ze-hydromolecular kunye ne-intermolecular ye-hydrogen ye-hydrogen, ekunzima ukuyinyibilikisa emanzini.

Kwaye kunzima ukunyibilikisa zonke izinyibilikisi eziphilayo. Nangona kunjalo, emva kokuthengiswa kwe-seluplose, amaqela ee-ERE azaziswa kwi-molecular thein,

Ngale ndlela, iimbophelelo ze-hydrogen ngaphakathi nangaphakathi kweemolekyuli zeselphulose zitshatyalalisiwe, kwaye i-hydrophility iphuculwe, ukuze i-sotaity yayo ingaphuculwa.

iphuculwe kakhulu. Phakathi kwazo, umzobo 1.1 Ngaba ubume ngokubanzi beeyunithi ezimbini ze-anhydroglucose zeselfowuni molecular cein, i-R1-R6 = h

okanye izinto eziphilayo. 1.2 sisiqwenga sebhokisi ye-carboxymethyl hydroxyyl seluplose chain, inqanaba lokufaka endaweni yebhokisi ye-carboxymethyl yi-0.5,4

Inqanaba lokufaka endaweni ye-hydroxyylyl yi-2.0, kwaye isidanga sokufaka endaweni ye-Molar siyi-3.0.

Kwisithuba ngasinye se-seluplose, inani lilonke le-etherhesition linokubonakaliswa njengenqanaba lokufaka endaweni (DS). yenziwe ngeentsinga

Ingabonwa ukusuka kwisakhiwo semolekyuli eyintloko esikuyo isidanga sokufaka endaweni ye-0-3. Oko kukuthi, i-anhhydroglucose ye-anhydroglucose ye-seluplose

, Inani eliphakathi lamaqela e-hydroxyl lithathwe ngamaqela okuqinisekisa amaqela earhente yokuthetha. Ngenxa yeqela le-hydroxalkyl ye-sellyulose, intembeko

I-etherhest kufuneka iqalwe kwiqela elitsha le-hydroxyl yasimahla. Ke ngoko, inqanaba lokufakwa endaweni yolu hlobo lwe-ether eselfowuni inokubonakaliswa kwi-moles.

isidanga sokufakwa endaweni (ms). I-SORE-EYENZIWEYO YOKWENZA UMSEBENZI WOKUGQIBELA Ibonisa ubungakanani bearhente yokuthambisa yongezwa kwicandelo ngalinye le-anhydroglsucose ye-seluplose

Ubunzima obuqhelekileyo beendawo eziphila ngokutsha.

1.2.2 Ukwahlulahlula kweeselwase

Nokuba i-Seulsulose i-Telulose Tost i-ewethu okanye ixutywe, iipropathi zabo zahlukile. I-selsulose macromoleules

Ukuba iqela le-hydroxyl ye-ring yamacandelo lithathwe liqela le-hydrophilic, imveliso inokuba nenqanaba eliphantsi lokufaka endaweni yemeko yenqanaba lokufakelwa.

Inokuqina okuthile kwamanzi; Ukuba ithathelwe indawo yeqela le-hydrophobic, imveliso inenqanaba elithile lokufakelwa kuphela xa inqanaba lokufaka endaweni yokongamela.

Imveliso enyibilikayo yamanzi, engafakwanga abathathe indawo ye-Elesuplose ye-Selelise inokuntywila emanzini, okanye inyibilikiswe kwizisombululo ze-alkali ezijolise kuzo

embindini.

Ngokweentlobo zezicelo ezithengisa izinto, ii-seluplose iiringi zinokwahlulwa zangamacandelo amathathu: amaqela e-alkyl, anjenge-Methyl Sellulose;

I-HYDROXBYKKSLs, ezinjenge hydroxyyl seluplose, hydroxypropyl sellulose; abanye, njenge-carboxymethyl sellyulose, njl njl.

Ukuhlelwa, Selese Sethen anokwahlulwa kwi: ionic, njenge carboxymethyl sellyulose; I-no-Ionic, enjenge-hydroxyylyl sellyulose; ixutywe

Uhlobo, njenge-hydroxyyl carboxethmethyl sellyulose. Ngokutsho kokuhlelwa kwe-solidality, isellulose inokohlulwa ibe: inyibilika amanzi, efana ne-carboxymethyl seluplose,

I-Hydroxyylyl sellulose; I-infolling-insozime, efana neMethyl Selelise, njl njl.

1.2.3 Iipropathi kunye nokusetyenziswa kweselselese

I-Teluplose Ether luhlobo lwemveliso emva kokulungiswa kwe-elsurise, kwaye i-Selesese I-Ether ineempawu ezininzi ezibaluleke kakhulu. njenge

Inepropathi yokwakha ifilimu; Njengomshicileli wokuprinta, inamandla amahle okuzola kwamanzi, iipropathi ezinkulu, ukugcinwa kwamanzi kunye nokuzinza kwamanzi;

5

I-ether ecacileyo yi-odorght, engenatyhefu, kwaye inetyhefu elungileyo. Phakathi kwabo, i-carboxeymethyl seluplose (CMC) ine "i-curimid monosodium glutamate"

igama lesidlaliso.

1.2.3.1 Ukuqulunqwa kwefilimu

Inqanaba lokuthengiswa kwe-elsulose i-Ether linempembelelo enkulu kwipropathi yayo yokwenza ifilimu efana nokwenza ubuchule bokwenza ifilimu kunye namandla aphezulu. I-Selersese Ether

Ngenxa yamandla akhe amahle kunye nokuhambelana okuhle kunye nokubuya kwawo, kunokusetyenziswa kwiifilimu zeplastiki, iifilimu kunye nezinye izinto.

ukulungiselela izinto ezibonakalayo.

1.2.3.2 Ukuzalwa

Ngenxa yobukho bamaqela amaninzi e-hydroxyl kwi-ring yeyunithi ye-telucose, i-selupelose ees ineempawu ezingcono kakhulu. kwaye

Kuxhomekeka kwi-Setesuse Ether endaweni yokufaka endaweni kunye nenqanaba lokufakwa endaweni, kukho ukukhetha okwahlukileyo kwezinyibilikisi zezinto eziphilayo.

1.2.3.3 Ukuthambisa

I-Telupelose Ether inyibilikisiwe kwisisombululo se-ACLAID ngohlobo lwe-colloid, apho inqanaba le-polymerization ye-Selelose ether ichaza i-selsulose

I-viscosity yesisombululo se-ether. Ngokungafaniyo nolwelo lweNewtonian, i-viscosity yesisombululo se-seluplose iguquka ngemisebenzi yeShear, kwaye

Ngenxa yolu lwakhiwo lweMacromolecules, i-viscosity yesisombululo iya kunyuka ngokukhawuleza kunye nokunyuka komxholo oqinileyo we-selsulose ether, nangona kunjalo isisombululo se-viscofity

I-Viskosity ikwancipha ngokukhawuleza nangokwandisa ubushushu [33].

1.2.3.4 ukonakaliswa

Isisombululo se-selsulose i-selselose i-Seles sichithwe emanzini kangangexesha elithile siya kukhulisa iintsholongwane, ngaloo ndlela ukuvelisa intsholongwane ye-enzyme kunye nokutshabalalisa iSigaba se-Selese.

I-Glucose ye-Glucose ye-Glucose i-Glucose Bonds, ngaloo ndlela kuncitshiswa ubunzima bemolekyuli ye-macromoleule. Ke ngoko, iseluplose ehafu

Ukulondolozwa kwezisombululo ezinamandla kufuna ukongezwa kwenani elithile lezinto ezigciniweyo.

Ukongeza, i-Selesese ineempawu ezininzi ezizodwa ezinje ngemisebenzi engaphezulu, umsebenzi we-Ionic, uzinzo olunamafutha kunye nokongezwa

isenzo se-gel. Ngenxa yezi propati, i-seluplose ehafu zisetyenziswa kwii-skict, i-papermang, i-synticitiction, cosmetic, ukutya, iyeza,

Isetyenziswe ngokubanzi kumasimi amaninzi.

1.3 INTSHAYELELO YOKUGQIBELA EZIQHELEKILEYO

Ukusuka kwisishwankathelo sika-1.2 seluplose Ether, sinokubonwa ukuba izinto ezingafunekiyo zokulungiselela i-Ether ye-Teluplose yi-Cotton Selelise, kunye nomxholo wale ntloko

Kukusebenzisa i-selulose ekhutshwe kwizityalo eziluhlaza okwesityalo ukutshintsha i-cotton sellulose ukulungiselela i-selsese. Oku kulandelayo yintshayelelo emfutshane kwisityalo

isixhobo.

Njengezixhobo eziqhelekileyo ezinjengeoyile, amalahle kunye negesi yendalo zinciphise, ukuphuculwa kweemveliso ezahlukeneyo ezisekwe kuzo, ezinje ngeefilimu ze-fiber kunye neefilimu zefibres, ziya kuthi zithintelwe ngakumbi. Ngophuhliso oluqhubekayo loluntu kunye namazwe kwihlabathi liphela (ngakumbi

Lilizwe eliphuhlisiweyo) elinikela ingqalelo kwingxaki yokungcoliseka kwendalo. I-Selelose yendalo inolungelelaniso lwe-biodegradiance kunye nolungelelaniso lwendalo esingqongileyo.

Ngokuthe ngcembe iya kuba yeyona nto iphambili kwizixhobo zefibber.
