Uphuhliso kunye nosetyenziso lweCellulose Ether

I-Cellulose ethers iqhubekile nophuhliso olubalulekileyo kwaye yafumana usetyenziso olubanzi kuwo wonke amashishini awohlukeneyo ngenxa yeepropathi zazo ezizodwa kunye nendalo eguquguqukayo. Nantsi isishwankathelo sophuhliso kunye nokusetyenziswa kwe-cellulose ethers:

1. Uphuhliso lwezeMbali: Uphuhliso lwe-cellulose ethers lubuyela ekupheleni kwekhulu le-19, kunye nokufunyanwa kweenkqubo zokuguqula iikhemikhali ze-cellulose. Iinzame zakwangoko zigxile kubuchule bokuphuma kwezinto ukwazisa amaqela e-hydroxyalkyl, afana ne-hydroxypropyl kunye ne-hydroxyethyl, kumqolo we-cellulose.
2. Ukuguqulwa kweMichiza: I-ethers ye-cellulose idityaniswe ngokuguqulwa kweekhemikhali zeselulosi, ngokuyinhloko nge-etherification okanye i-esterification reactions. I-Etherification ibandakanya ukutshintshwa kwamaqela e-hydroxyl ye-cellulose kunye namaqela e-ether, ngelixa i-esterification ithatha indawo yamaqela e-ester. Olu hlengahlengiso lunikezela ngeempawu ezahlukeneyo kwi-cellulose ethers, njengokunyibilika emanzini okanye kwi-organic solvents, isakhono sokwenza ifilimu, kunye nolawulo lwe-viscosity.
3. Iindidi ze-Cellulose Ethers: Ii-ether ze-cellulose eziqhelekileyo ziquka i-methyl cellulose (MC), i-hydroxypropyl cellulose (HPC), i-hydroxyethyl cellulose (HEC), i-carboxymethyl cellulose (CMC), kunye ne-hydroxypropyl methyl cellulose (HPMC). Uhlobo ngalunye luneempawu ezizodwa kwaye lufanelekile kwizicelo ezithile.
4. Izicelo kuLwakhiwo: I-Cellulose ethers isetyenziswa kakhulu kushishino lokwakha njengezongezo kwimathiriyeli yesamente, njengodaka, i-grouts, kunye neemveliso ezisekwe kwigypsum. Baphucula ukusebenza, ukugcinwa kwamanzi, ukubambelela, kunye nokusebenza ngokubanzi kwezi zixhobo. I-HPMC, ngokukodwa, iqeshwe kakhulu kwii-adhesives ze-tile, i-renders, kunye ne-self-leveling compounds.
5. Ukusetyenziswa kuMachiza: I-ethers ye-Cellulose idlala indima ebalulekileyo ekuxutyweni kwamayeza njengezibophelelo, ii-disintegrants, ii-film-formers, kunye nezilungisi ze-viscosity. Ngokuqhelekileyo zisetyenziselwa ukugqoka iipilisi, iifomyula ezilawulwayo, ukumiswa, kunye nezisombululo ze-ophthalmic ngenxa ye-biocompatibility yazo, ukuzinza, kunye neeprofayili zokhuseleko.
6. Ukusetyenziswa koKutya kunye noNyango loBuqu: Kushishino lokutya, i-cellulose ethers isetyenziswa njengezinto ezityebisayo, izizinzisi, kunye neziminyinyili kwiimveliso ezininzi, ezibandakanya iisosi, iilokhwe, iimveliso zobisi, kunye nezinto ezibhakiweyo. Kwiimveliso zokhathalelo lomntu, zifumaneka kwintlama yamazinyo, ishampu, iiloshini, kunye nezithambiso zokuqina kwazo kunye neempawu zokuthambisa.
7. Iingqwalasela zokusiNgqongileyo: Iellulosi ethers ngokuqhelekileyo zithathwa njengezinto ezikhuselekileyo nezinobuhlobo nokusingqongileyo. Ziyakwazi ukubola, zivuseleleke, kwaye azinatyhefu, zizenza zibe nomtsalane kwiipolymers zokwenziwa kwizicelo ezininzi.
8. UPhando oluqhubekayo kunye noTshintsho: Uphando kwi-cellulose ethers luqhubela phambili, lugxininise ekuphuhliseni izinto eziphuma kwinoveli ezineempawu eziphuculweyo, ezifana nobuntununtunu bobushushu, ukuphendula kwe-stimuli, kunye ne-bioactivity. Ukongeza, iinzame ziyaqhubeka zokuphucula iinkqubo zemveliso, ukuphucula ukuzinza, kunye nokuphonononga usetyenziso olutsha kwiinkalo ezivelayo.

I-cellulose ethers imele udidi oluguquguqukayo lweepolima ezinoluhlu olubanzi lwezicelo kuwo wonke amashishini. Uphuhliso kunye nokusetyenziswa kwabo kuqhutywe luphando oluqhubekayo, ukuqhubela phambili kwezobuchwepheshe, kunye nesidingo sezinto ezizinzileyo nezisebenzayo kumacandelo ahlukeneyo.
