Cellulose Ether Inkunga ni icyiciro cya kamere yahinduwe na selile. Bitewe n'amazi yabo meza cyane, imikorere yo guhinduranya ubushishozi no kwiyumvisha imiterere yo hanze nkubushyuhe na PH, bikoreshwa cyane mubikoresho byo kubaka, aho bihurira, imiti, ibiryo no kwisiga. Igikorwa cyo kurwanya virusi ya selile ether ni kimwe mu biranga ishingiro rya porogaramu yagutse mu masomo menshi yinganda na buri munsi.
1. Imiterere n'ibyiciro bya elerale
Ubugari bwa Centreulose bakomoka kuri selile biteguye kuva kuri selile karemano binyuze mubyahuye. Cellulose ni ikigo cya polymer cyakozwe na glucose monomers ifitanye isano na β-1,4-glycosic. Inzira yo gutegura ya selile ubusanzwe ikubiyemo gufata hydroxyl (-Oh) igice cya selile hamwe numukozi wabuze kugirango ubyarebwe na selile yo kubyara ibidukikije bitandukanye nabasimburana, HydroxyIjorol, HydroxyPropyl, nibindi).
Ukurikije abasimbuye, abasivili basanzwe barimo ibitero birimo methyl Methoulose (HPMXYethyl Methyl Methyl Methys yo guhinduranya hamwe na vino. Umubare n'umwanya w'abasimbuye ntabwo bigira ingaruka gusa ku gukira kwamazi gusa, ariko kandi bifitanye isano nabyo mu buryo butaziguye viscosity yo gukora ubushobozi mu bisubizo bitangaje.
2. Uburyo bwo gushinga vino
Ubukwasi bugenga ingaruka za bahanga ba selile zituruka ku iseswa ryabo mu mazi no mu myitwarire yo kwagura iminyururu ya molekile. Iyo etage ya selile yasheshwe mumazi, imitwe ya polar igira isuku ya hydrogen hamwe na molekile yamazi, bituma "molekile zamazi" zigenda ziyongera mumazi imbere, bityo wongere ubukandara imbere, bityo wongere ubukangurambaga bwimbere, bityo wongere ubutwari bwimbere bwigisubizo.
Ubunini bwa vinolity bufitanye isano rya bugufi nuburemere bwa molekile, ubwoko bwasimbuwe, urwego rwo gusimbuza (DS) nurwego rwa polymerizira (DP) ya elegiteri. Mubisanzwe, nini nini yuburemere bwa moleki zubugari bwa selile kandi ndende urunigi rwa molekile, hejuru ya virusire yumuti. Muri icyo gihe, abasimbuye batandukanye bigira ingaruka kuri hydrophilition ya selile ether molekile, bityo bikagira ingaruka ku bukenguzi bwabo no gusya mumazi. Kurugero, HPMC ifite amazi meza yoroheje nubukungu bwa viscosity bitewe na hydroxy opesippopyle na methyl. CMC, ariko, ifite ubushishozi bwo hejuru kuko itangiza amatsinda ya Carboxyyy yashizwemo, ashobora gusabana cyane na molekile y'amazi mu gisubizo cy'amazi.
3. Ingaruka zintura hanze kuri viscosity
Ibyatsi bya selile ether biterwa nimiterere yacyo gusa, ariko no ku bintu byo hanze gusa, harimo n'ubushyuhe, agaciro ka PH, Ion Mentration, n'ibindi.
3.1 Ubushyuhe
Ubushyuhe nikintu cyingenzi kigira ingaruka kuri viscolity ya selile ether igisubizo. Mubisanzwe, viscosiya yubukorikori bwamateka igabanuka hamwe nubushyuhe. Ibi ni ukubera ko kwiyongera kwihuta kwihutisha MoleCure ya molekile, igabanya imikoranire iri hagati ya molekile mumazi kugirango yiyongere, bigabanye ingaruka zamazi, bigabanya ubukuru. Ariko, bahanganye na seliki, nka HPMC) bagaragaza imiterere yubushyuhe mubushyuhe bwihariye, nibyo, nkuko ubushyuhe bwiyongera, ibiti byiyongera, amaherezo yumuti wiyongera kandi amaherezo bigizwe na gel.
3.2 PH agaciro
Agaciro PH karimo ingaruka zikomeye kuri viscolity ya selile. Kuri enerel bahanganye na selile bafite abasimbuye Ionic (nka CMC), agaciro ka PH bigira ingaruka kubiremwa birebire mubisubizo biri hagati ya molekile hamwe na viscosiya. Ku ndangagaciro zirenga, itsinda rya kanseri ni ionized, bikaviramo kwanga gukomera electrostatike, bigatuma urunigi rufite imbaraga zoroshya rudashoboka kandi rwongera viscosiya; Mugihe ku ndangagaciro zo hasi ya PH
3.3 ion kwibanda
Ingaruka za ion kwibanda kuri viscosity ya selile biragaragara cyane. Ubugari bwa selile hamwe na ionic abasimbuye bizaterwa ningaruka zikingira ion yo hanze. Nkuko ion yibanda kubisubizo byiyongera, ion yo hanze izaca intege ingwate ya electrostatike hagati ya selile, bityo bigatuma urunigi rwa molekile rufata neza, bityo bigabanya urunigi rwibisubizo. Cyane cyane mubidukikije, viscosiya za CMC izagabanuka cyane, ifite akamaro gakomeye kubishushanyo mbonera.
4. Kugenzurwa na vino muburyo bwo gusaba
Ubugari bwa Cellulose bwakoreshwaga cyane mumirima myinshi kubera imikorere myiza ya virusi nziza.
4.1 Ibikoresho byo kubaka
Mu bikoresho byo kubaka, ether ether (nka hpmc) ikunze gukoreshwa mu miterere yumye, ifu ivanze hamwe n'ibindi bicuruzwa kugirango uhindure amazi kuvange kandi uzamure imitungo no kurwara mugihe cyo kubaka. Muri icyo gihe, birashobora kandi gutinza guhumeka, kunoza uburyo bwo kugumana amazi, bityo bikanoza imbaraga nimbaro yibicuruzwa byanyuma.
4.2 IHURIRO N'IBIKORWA
EXESUUGARA ENLONS ikora nk'abarimbyi n'intangarugero mu mavuta ashingiye ku mazi na wino. Muguhindura viscosity, baremeza ko aringaniye no gupfukaho mu gihe cyo kubaka. Byongeye kandi, irashobora kandi kunoza induru yo kurwanya ipfunyika, kugabanya kunyeganyega, no gukora kimwe nubwubatsi.
4.3 Ubuvuzi n'ibiryo
Mu rwego rw'ubuvuzi n'ibiryo, abashiraho selile (nka HPMC, CMC) bakunze gukoreshwa nk'abarimbyi, emalifiers cyangwa intandaro. Kurugero, HPMC, nkibikoresho byo gupfukira ibisate, birashobora kugera ku ngaruka zikomeje kureka ibiyobyabwenge ugenzura igipimo cy'ibisebe. Mu biryo, CMC ikoreshwa mu kongera viscosity, kunoza uburyohe, no kwagura ubuzima bw'ibiryo.
4.4 Amavuta yo kwisiga
Gushyira mu bikorwa abakoresha selile muri kwisiga bibanze cyane mu bicuruzwa nko kumarana, gels na masike yo mumaso. By adjusting the viscosity, cellulose ethers can give the product appropriate fluidity and texture, and form a moisturizing film on the skin to increase comfort during use.
Ubugari bwa Cellus bakomoka kuri selile birashobora kugenzura neza viscosity yibisubizo binyuze muburyo bwabo bwihariye bwa molecular hamwe nibidukikije byo hanze. Ibi byatumye basaba mu mirima myinshi nko kubaka, imiti, ibiryo, no kwisiga. Hamwe no guteza imbere ubumenyi n'ikoranabuhanga mu ikoranabuhanga, imirimo ya selile izagukwa kurushaho gukemura ibisubizo byumvikana neza kubijyanye n'imirima myinshi.
