Imyenda yo hanze igira uruhare runini mukurinda inyubako ibidukikije, gutanga ubwiza bwubwiza no kwemeza kuramba. Twinjiye mumiterere ya selile ya selile, uruhare rwabo nkibibyimbye hamwe na rheologiya ihindura, hamwe ningaruka zinyongeramusaruro kumitungo nka adhesion, ikirere, hamwe nuburambe muri rusange. Kubashinzwe gukora nababikora bagamije guteza imbere ubuziranenge bwo hanze, gusobanukirwa neza nibi bikoresho nibyingenzi.
kumenyekanisha:
Imyenda yo hanze irakomeye mukurinda inyubako ikirere kibi, imirasire ya UV, umwanda nibindi bidukikije. Ether ya selile ikomoka kumasoko ya selile isanzwe hamwe ninyongeramusaruro nyinshi bigira uruhare runini mukuzamura iyi myenda.
Ether ya selulose mu rukuta rwo hanze:
2.1. Incamake ya selile ya selile:
Ethers ya selile irimo methylcellulose (MC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), nibindi bikoreshwa cyane mubikorwa byo hanze kubera imiterere yihariye. Irangi. Iyi polymers ikora nkibibyimbye, ibifunga, hamwe na rheologiya ihindura, itanga impuzu ibintu byingenzi.
2.2. Umubyimba:
Ether ya selile ikora neza cyane yongerera ubwiza bwimyenda, igatera imbere kandi igabanya kugabanuka. Imiterere ya molekulire ya selile ya selile ni amazi-adasubira inyuma, yemeza neza neza kandi neza.
2.3. Guhindura imvugo:
Kugenzura imyitwarire ya rheologiya yimyenda yo hanze ningirakamaro kugirango ugere kubintu byifuzwa. Ethers ya selile igira uruhare runini muguhindura rheologiya yimyenda, kunoza imigendekere yimiterere. Ibi byongera ubworoherane bwibikorwa kandi bivamo ubunini bumwe.
Inyongera zo kunoza irangi ryo hanze:
3.1. Umujyanama wa Adhesion:
Adhesion nikintu cyingenzi kigira ingaruka kumikorere yurukuta rwinyuma. Inyongeramusaruro zitandukanye, nka silanes na polymers ya acrylic, byongera gufatana mugutezimbere ubumwe bukomeye hagati yigitereko na substrate. Ibi byemeza igihe kirekire kandi kirwanya gukuramo ibisebe.
3.2. Ikirere cyiyongera:
Irangi ryo hanze rihura nikirere gitandukanye, harimo urumuri rwizuba, imvura, nihindagurika ryubushyuhe. UV stabilisateur, ibangamira urumuri rwa amine (HALS), nibindi byongeweho ikirere birinda impuzu kwangirika guterwa nimirasire ya UV hamwe na okiside, bityo bikongera ubuzima bwabo.
3.3. Imiti igabanya ubukana na mikorobe:
Ubuso bw'inyuma bushobora gukura ku binyabuzima, harimo ibumba na algae. Kwiyongera kwa antifungal na antibacterial agent (nka biocide) birinda imikurire ya mikorobe kandi bikomeza kugaragara no kuramba.
3.4. Umukozi utarinda amazi:
Ibikoresho bitarinda amazi ni ngombwa mu gusiga amarangi hanze kugirango birinde amazi kwinjira, bishobora gutuma imikorere yangirika no gutakaza. Silicone, silanes hamwe n’ibintu bya fluor bikoreshwa cyane mu kwangiza amazi bitera inzitizi ya hydrophobique kandi bikongera imbaraga zo kurwanya amazi.
3.5. Ingaruka zo kurwanya imbaraga:
Ubuso bw'inyuma bushobora kwibasirwa n’ibyangiritse biva ahantu hatandukanye, harimo urubura cyangwa guhuza umubiri. Kwiyongera kwingaruka-zirwanya imbaraga, nka elastomeric polymers cyangwa microsperes, birashobora kunoza ubushobozi bwikibiriti cyo guhangana nihungabana ryimashini no gukomeza kurinda.
Imikoranire hagati ya selile ethers ninyongera:
Ihuriro rya selile ethers hamwe ninyongera mumarangi yo hanze akenshi bitera imbaraga zo guhuza ibikorwa bitezimbere imikorere rusange. Imiterere ya thixotropique ya selulose ethers yuzuza gukwirakwiza no gutuza ibintu bimwe byongeweho, kunoza imikoreshereze no gukora firime.
Inyigo n'ingero:
Iki gice gitanga ingero-zifatika zerekana amarangi yo hanze asize amarangi ahuza selile ethers hamwe ninyongera zitandukanye. Ubushakashatsi bwakozwe bwerekana ibibazo byihariye byakemuwe, iterambere ryagezweho, hamwe nitsinzi rusange ryakozwe mugihe cyibidukikije bitandukanye.
Ibizaza hamwe nudushya:
Mugihe icyifuzo cyo kwambara neza cyane cyimbere gikomeje kwiyongera, inganda zirimo kubona ubushakashatsi niterambere. Ibizaza ejo hazaza hashobora kuba harimo guhuza ibifuniko byubwenge, nanomateriali yateye imbere hamwe ninyongeramusaruro zirambye kugirango turusheho kunoza igihe kirekire, kubungabunga ibidukikije no gukoresha ingufu.
mu gusoza:
Cellulose ethers ninyongera bigira uruhare runini mugutezimbere imikorere yimyenda yo hanze. Gusobanukirwa neza imiterere n'imikoranire yabo nibyingenzi kubashinzwe gukora no gukora ibicuruzwa bashaka guteza imbere ibifuniko hamwe nigihe kirekire, gufatana, ikirere hamwe nubuziranenge muri rusange. Iterambere rikomeje mu bikoresho n’ikoranabuhanga muri uru rwego bitanga ibyiringiro byo gukomeza gutera imbere mu myenda yo hanze y’inganda zubaka.
