HEC ya Detergent

HEC Hydroxyethyl selulose ni umweru wijimye wijimye cyangwa ifu ikomeye. Ntabwo ari uburozi, uburyohe. Ni ether ya selulose ether, ishonga mumazi akonje kandi ashyushye bitewe na hydrophilique hydroxyethyl muri molekile. Igisubizo cyacyo cyamazi gifite pH agaciro ka 6.5 ~ 8.5 kandi gihamye kugirango ubushyuhe. HEC ifite ibisubizo bitandukanye ukurikije urwego rwo gusimbuza (DS). Kudashonga mumashanyarazi menshi. Ifite imiterere yo kubyimba, guhagarikwa, gufatira, emulisile, gutatanya no kugumana ubushuhe, nibindi, kandi irashobora gutegura ibisubizo hamwe nuburinganire butandukanye. Ifite umunyu mwiza udasanzwe kuri dielectric, kandi igisubizo cyamazi cyemerewe kuba kirimo imyunyu myinshi kandi ntigikomeze.

Hydroxyethyl selile HECkubyara ibikoresho fatizo

Ibikoresho fatizo byingenzi: Umujyi wa selile (pamba staple cyangwa pulp nkeya), alkali yamazi, okiside ya Ethylene, diron ya Ethylene (40%)

Sisitemu ya fibre ya fibre ni polymer karemano, buri mpeta ya fibre irimo amatsinda atatu ya hydroxyl, reaction ya hydroxyl ikora cyane kugirango ikore hydroxyethyl selile. Shira ipamba mbisi cyangwa ifunguro ryuzuye muri 30% ya alkali yamazi mugihe cyigice cyisaha hanyuma ukande. Kumenagura kugeza 1: 2.8 byamazi ya alkaline, hanyuma ujanjagure. Selulose ya alkali yajanjaguwe ishyirwa mu isafuriya ya reaction, igafungwa, ikangurwa, ikuzuzwa azote, ikongera ikazunguruka kandi ikuzuzwa azote kugira ngo isimbuze umwuka muri urwo rubanza. Amazi ya Ethylene yabanje gukonjeshwa yashyizwe mu ikoti ya reaktor n'amazi akonje, kandi reaction yagenzuwe nka 25C kuri 2h kugirango ibone ibicuruzwa bya hydroxyethyl fibre fibre. Ibicuruzwa bitarimo inzoga zo gukaraba, ongeramo aside ya acetike muri VLL 46, jean ongeramo glyoxal crosslinking gusaza. Noneho oza n'amazi, centrifugal dehydrasi, yumisha, usya, hydroxyethyl selulose.

1.1 alkali

Ibicuruzwa byera ni ibara ritagira ibara. Ubucucike bugereranijwe 2. 130, gushonga 318.4C, ingingo itetse 1390C. Soda ya Caustic ku isoko ifite imiterere yizunguruka. Kandi amazi yubwoko bubiri: soda ikomeye ya caustic soda yera, flake, blok, imiterere ya granular ninkoni, cytoplazme: soda yamazi ya caustic soda yitwa alkali yamazi, idafite ibara ritagaragara. Ibicuruzwa bikomoka mu nganda birimo umwanda, cyane cyane sodium chloride na sodium ya karubone, ndetse rimwe na rimwe bike bya okiside ya fer.

1.2 okiside ya Ethylene

Okiside ya Ethylene ni ifumbire mvaruganda, imiti ya C2H40, ni kanseri yuburozi. Epoxy inkoni irashya kandi iraturika, ntabwo byoroshye gutwara kure cyane, kuburyo hariho akarere gakomeye. Ikoreshwa cyane mu gukaraba, gukora imiti, gucapa no gusiga amarangi. 3 oxyethane (E0) ni ether yoroshye yimpeta, ni iyimvange ya heterocyclic, nibicuruzwa byingenzi bya peteroli. Oxide ya Ethylene ni ibara ritagira ibara rifite ubushyuhe buke na gaze itagira ibara ifite impumuro nziza yamaguru kubushyuhe bwicyumba. Umuvuduko wumwuka wa gaze ni mwinshi kandi urashobora kugera kuri 141kPa kuri 30C. Umuvuduko mwinshi wumuyaga ugena kwinjirira gukomeye kwa epoxy z.alkane mugihe ugenda. Ingingo yo gushonga (C): -112.2. Ubucucike bugereranijwe (amazi -1): 0.8711

1.3 glyoxal

Urubavu rw'umuhondo cyangwa rudasanzwe, ruhinduka umweru ku gukonja.

Shyiraipamba cyangwa ipamba inoze muri 30% lye. Kuraho hanyuma ukande. Icyo gihe irajanjagurwa hanyuma igasubizwa hamwe na okiside ya Ethylene yabanje gukonjeshwa kugirango itange hydroxyethyl selile. Noneho kwoza n'inzoga hanyuma ushyiremo aside acike kugirango ukarabe kandi utabogamye. Noneho shyiramo glyoxal crosslinking gusaza, gukaraba vuba n'amazi. Hanyuma, nyuma ya centrifugation dehydrasiyo, kumisha no gusya, byarangiyeHECibicuruzwa byabonetse.

Uburyo bwo kubyara ivu ritoHEChydroxyethyl selulose mugukomeza gukaraba ni murwego rwa tekiniki yibikoresho. Ikibazo cya tekiniki kigomba gukemurwa ni ugutanga uburyo bukomeza bwo gukaraba hamwe nubushobozi buhanitse, igihombo gito cyo gukaraba hamwe nibikoresho hamwe nigiciro gito kugirango bitange ivu ritoHEChydroxyethyl selile. Uburyo bwo gukomeza gukaraba kugirango butange ivu rikeHEChydroxyethyl selulose irangwa mu ntambwe zikurikira: A, hydroxyethyl selulose itavanze hamwe na agent ihuza imiti ivanze, kuvura guhuza kugirango ubone A; B. Ongeraho gukaraba kumashanyarazi A wabonye muntambwe A kugirango ubone B; C. Ongeramo ibishishwa C byabonetse mu ntambwe B muri centrifuge yumuvuduko hanyuma ubone hydroxyethyl selulose ivu nkeya nyuma yo gukaraba. Uburyo burashobora kunoza cyane imikorere yakazi, kunoza cyane igihombo cyo gukaraba hamwe nibikoresho, kandi bikagabanya cyane ivu ryibicuruzwa, bikwiye kwamamara no kubishyira mubikorwa.
