Umatshini wokuthambisa kwendlela yeselselee kwi-Ether kwizicelo ezahlukeneyo

I-Telupelose Ether yiklasi yezixhobo ezinyibilikayo zamanzi ezifunyenwe ngokutshintsha kweekhemikhali zeselutali yendalo. I-Selesupilose eqhelekileyo i-methyl seluplose (MC), i-HydroxyEtheetheethy (Hec), i-Hydroxdpropyl Methyl Selelose (HPMC), njl. Njl.), Njl. Njl. Eyona ndlela iphambili njenge-thi coker iquka iipropathi zomzimba kunye nekhemikhali yentsebenzo phakathi kwemo yemolekyuli kunye nesisombululo.

1. Ubume bemolekyuli ye-seluplose ether
I-Telupelose Ether isenziwa ngokwazisa ngezinto ezahlukeneyo (ezinjenge-methyl, i-ethyl, hydroxypropy, njl.) Kwi-chain yendalo. Le nkqubo igcina ubume belayini yeselselose kodwa utshintsha isoba kunye nokuziphatha kwesisombululo. Ukuqaliswa kwezinto ezithatha izinto kwenza ukuba iSelecelise inomoya olungileyo emanzini kwaye unokwakha inkqubo yokuziqhelanisa nesisombululo, esibalulekileyo kwintsebenzo yayo.

2. Ukuziphatha kwemolekyuli kwisisombululo
Isiphumo sokuqaqamba kwe-tartulose Ether emanzini ikakhulu ivela kwi-viscofity yenethiwekhi ephezulu ye-viscovity eyenziwa ziimolekyuli zayo kwisisombululo. Iindlela ezithile zibandakanya:

2.1 ukudumba kunye nokuzolula imixokelelwane yemolekyuli
Xa i-ersesese i-Ether inyibilikisiwe emanzini, imixokelelwane yayo ye-macromolecular iya kudumba ngenxa ye-hydration. Ezi zinto zidumbileyo zidumbile ziya kunxunguphalo kwaye zinevolumu enkulu, enyusa kakhulu i-viscomosity yesisombululo. Oku kusolula kwaye ukudumba kuxhomekeke kudidi kunye nenqanaba lokufakwa endaweni ye-Selese i-selsulose ether, kunye nexabiso lobushushu kunye nexabiso le-pH lesisombululo.

2.2 I-Intermolecular Hydrogen Bonds kunye nokudibana kwe-hydrophobic
I-selsulose ether molecular iqhinga elininzi lamaqela amakhulu e-hydroxyl kunye nezinye ii-hydrophilic, ezinokwenza iimolekyuli ezinamandla ngeemolekyuli zamanzi nge-hydrogen. Ukongeza, izinto zokuthabatha i-etelulose i-ether zihlala zinenqanaba elithile le-hydrophobic, kwaye la maqela e-hydrophobic angenza i-hydrophotic axhase amanzi emanzini, ngaloo ndlela aphucule i-viscosity yesisombululo. Iziphumo ezidityanisiweyo ze-hydrogen bonds kunye nokudibana kwe-hydrophobic kuvumela isisombululo se-Seles sese ukuze senze isimo se-viscofity ephezulu.

2.3 Ukuncoma kunye nokuncoma komzimba phakathi kweemolekyuli
I-selsulose ether molecular i-molecular iyobuza i-pertsunts yomzimba kwisisombululo ngenxa yentshukumo ye-thermal kunye nemikhosi ye-intermolecular, kwaye ezi zingenayo zinyusa i-viscosity yesisombululo. Ukongeza, ngamacala aphezulu, iimolekyuli ze-ertulose e-Ether zinokwenza isakhiwo esifanayo sokunxibelelanisa ngokwasemzimbeni, okuqhubekayo luhlobo lwesisombululo.

I-3. Iindlela zokonwaba kwizicelo ezithile

3.1 Izinto zokwakha
Kwizinto zokwakha, isellulose ehafu zihlala zisetyenziswa njengamanzi amakhulu esifakiweyo kunye nekhredithi. Banokwandisa ukusebenza kwendlela yokwakha kunye nokugcinwa kwamanzi, ngaloo ndlela ukuphucula indawo yokwakha kunye nomgangatho wokugqibela wezakhiwo. Isiphumo sokuqaqamba kwe-seluplose ethse kwezi zicelo kusetyenziswa izisombululo ze-viscofity ephezulu, ukwandisa imfuyo ye-adhes kunye ne-anti-i-anting yezinto.

3.2 Ishishini lokutya
Kumzi-mveliso wokutya, isellulose ehafu njenge-hydroxylcell methylcelceli (i-HPMC) kunye ne-hpmcroxyytethl seluplose (hec) isetyenziswa njenge-thissulose (hec) isetyenziswa njenge-eulsiber. Izisombululo ze-viscofity eziphezulu abazenzayo ekutyeni zinokongeza intshukumo kunye nokuthungwa kokutya, ngelixa uzinzisa inkqubo ekusasaziweyo ekutyeni nokwahlukana.

3.3 amayeza kunye ne-cosmetics
Kwintsimi yamayeza kunye ne-cosmetics, i-seluplose ehafu zisetyenziswa njengearhente zokulungisa kunye neebhulethi zokulungiselela iimveliso ezinjengee-geses, ii-sures kunye neekhrim. I-curing swiceting ixhomekeke ekuphenduleni kwayo emanzini nasemagqabini enethiwekhi yenethiwekhi ye-viscofity eyenziweyo, ukubonelela ngozinzo kunye nokuzinza okufunwa yimveliso.

I-4. Impembelelo yezinto zokusingqongileyo kwifuthe lokutyibilika
Isiphumo esihle se-Ether se Selese sichaphazeleka ziintlobo ezahlukeneyo zendalo esingqongileyo, kubandakanya neqondo lobushushu, ixabiso le-pH kunye ne-Ionic yesisombululo. Ezi zinto zinokutshintsha isidanga sokudumba kunye nokunxibelelana kwe-intermolecular ye-selsulose ether molecular, ngaloo ndlela ichaphazela uVekyuli wesisombululo. Umzekelo, ubushushu obuphezulu buhlala bunciphisa isisombululo se-Selese i-selsulose ye-selselose, ngelixa utshintsho kwixabiso le-pH lunokutshintsha imeko ye-bin ye-molecular, ngaloo ndlela ichaphazela i-vickosity.

Ukusetyenziswa ngokubanzi kwe-ilsulose ether njenge-thi chorner kungenxa yesakhiwo sayo semolekyuli eyahlukileyo kunye nobume benethiwekhi ephezulu kakhulu eyenziwe emanzini. Ngokuqonda indlela yalo yokuqaqamba kwizicelo ezahlukeneyo, ukusebenza kwesicelo kwimimandla eyahlukeneyo yeshishini kunokuba ngcono. Kwixesha elizayo, kunye nophando olunzulu lolwalamano phakathi kwesakhiwo se-Ether ye-Ether kunye nokuSebenza, kulindeleke ukuba i-Selese isete ye-Eler Intuthuko engcono iya kuphuhliswa ukuze ifezekise iimfuno ezahlukeneyo.
