Selirulose ya Hydroxyethyl

Hydroxyethyl cellulose (HEC) ni ether ya cellulose idafite ionic isombaibikomoka ku bikomoka ku bimeraishobora kubana n'izindi polymer nyinshi zishobora gushonga mu mazi, surfactants, n'imyunyu. HEC ifite imiterere yo gukomera, gusunika, gufatana, emulsification, imiterere ihamye ya firime, gukwirakwira, kubika amazi, kurinda mikorobe no kurinda colloidal. Ishobora gukoreshwa cyane mu gusiga, kwisiga, gucukura peteroli n'izindi nganda.

Imiterere y'ingenzi yaHselulose ya ydroxyethyl(HEC)Ni uko ishobora gushonga mu mazi akonje n'amazi ashyushye, kandi nta miterere ya gel ifite. Ifite uburyo bwinshi bwo gusimbuza, gushonga no kuba mu buryo butandukanye. Ifite ubushyuhe bwiza (munsi ya 140°C) kandi ntitanga umusaruro mu gihe cy'imvura. Umuti wa hydroxyethyl cellulose ushobora gukora agahu kabonerana, gafite imiterere itari iyoni idakorana na iyoni kandi gafite imikoranire myiza.

Cibimenyetso bya HEC

1.Ubunini

HEC ni uburyo bwiza bwo gukurura irangi no kwisiga. Mu buryo bufatika, guhuza ubunini n'ubugari, umutekano, gukwirakwira no kubika amazi bizatanga umusaruro mwiza kurushaho.

2.Ubusembwa bw'ibishushanyo mbonera

Ibara rya Pseudoplasticity risobanura imiterere y'uko ubushyuhe bw'umuti bugabanuka uko umuvuduko wiyongera. Irangi rya latex ririmo HEC ryoroshye kurishyira hamwe n'uburoso cyangwa imipira kandi rishobora kongera uburyohe bw'ubuso, ibyo bikaba byanatuma akazi gakorwa neza; shampoo zirimo HEC zifite ubushyuhe bwiza kandi zirakomeye cyane, zoroshye kuzigabanya, kandi zoroshye kuzikwirakwiza.

3.Kwihanganira umunyu

HEC irahamye cyane mu bisubizo by'umunyu mwinshi kandi ntabwo ibora ngo ibe iyonic. Iyo ikoreshejwe mu gushushanya, ubuso bw'ibice byayo bushobora kuba bwuzuye kandi bukarabagirana. Igishimishije kurushaho ni uko igifite ubukana bwiza iyo ikoreshejwe mu irangi rya latex ririmo borate, silicate na karubone.

4.Gukora filime

Imiterere ya HEC mu gukora filime irashobora gukoreshwa mu nganda nyinshi. Mu gukora impapuro, gusiga irangi rigizwe na HEC bishobora kubuza amavuta kwinjira, kandi bishobora gukoreshwa mu gutegura ibisubizo byo gukora izindi mpapuro; mu gukora irangi, HEC ishobora kongera uburibwe bw'imigozi no kugabanya kwangirika kwayo. Mu gukora ingano, irangi no kurangiza umwenda, HEC ishobora gukora nk'ifiriti y'agateganyo irinda. Iyo uburinzi bwayo budakenewe, ishobora gukurwa kuri fibre n'amazi.

5.Kubika amazi

HEC ifasha mu gutuma ubushuhe bw'iyi sisitemu buguma mu buryo bwiza. Kubera ko HEC nke mu gikoresho cy'amazi ishobora kugira ingaruka nziza zo kubika amazi, bityo sisitemu ikagabanya ikiguzi cy'amazi mu gihe cyo kuyashyira mu byiciro. Iyo amazi adakomeje kugumana no gufatana, sima izagabanya imbaraga zayo n'uburyo ifatana, kandi ibumba naryo rigabanya ubushyuhe bwayo mu gihe cy'igitutu runaka.

Porogaramu

1.Irangi rya latex

Hydroxyethyl cellulose ni yo ikoreshwa cyane mu gukurura latex. Uretse gukurura latex, ishobora no gukurura, gukwirakwiza, gutuza no kubika amazi. Irangwa n'ingaruka zikomeye zo gukurura, gutera neza amabara, imiterere yo gukora filime no kugumana ubuziranenge. Hydroxyethyl cellulose ni ikomoka kuri cellulose itari ionic kandi ishobora gukoreshwa mu rugero rwa pH runini. Ifite ubushobozi bwo guhuza neza n'ibindi bikoresho biri muri iyo migabane (nk'amabara, inyongeramusaruro, ibintu byuzuza n'umunyu). Gukurura hydroxyethyl cellulose bifite rheology nziza na pseudoplasticity ku gipimo gitandukanye cyo gukata. Uburyo bwo kubaka nko koza, gukurura no gutera imiti burashobora gukoreshwa. Imiterere ni myiza, ntiyoroshye kuyitonyanga, kuyitemba no kuyisiga, kandi ubushobozi bwo kuyipima nabwo ni bwiza.

2.Ubwikorezi bwa polimeri

Hydroxyethyl cellulose ifite inshingano zo gukwirakwiza, gukurura, guhagarika no gushimangira igice cya polymerization cyangwa copolymerization cya resin ya synthetic, kandi ishobora gukoreshwa nk'itsinda ririnda. Irangwa n'ubushobozi bukomeye bwo gukwirakwiza, umusaruro uvamo ufite "film" ntoya, ingano nto y'uduce, imiterere imwe y'uduce, imiterere idasobanutse, amazi meza, ubwiza bw'umusaruro buri hejuru, kandi byoroshye gutunganya. Kubera ko hydroxyethyl cellulose ishobora gushonga mu mazi akonje n'amazi ashyushye kandi idafite ubushyuhe bwa gelation, ikwiriye cyane mu buryo butandukanye bwo gukwirakwiza polymerization.

Imiterere y'ingenzi y'ikinyabiziga gikwirakwiza amazi ni uburyo uburebure bw'ubuso (cyangwa imiterere y'ubuso), imbaraga z'ubuso hamwe n'ubushyuhe bw'amazi yacyo. Iyi miterere ya hydroxyethyl cellulose ikwiriye gukoreshwa mu gupolima cyangwa gupolima bya resins za sintetike.

Hydroxyethyl cellulose ihura neza n'izindi ether za cellulose zishonga mu mazi na PVA. Sisitemu igizwe n'ibi ishobora kugira ingaruka nziza zo kuzuza intege nke z'ibindi. Umusaruro wa resin ukorwa nyuma yo kuvanga ntugira ubuziranenge bwiza gusa, ahubwo unagabanya igihombo cy'ibikoresho.

3.Gucukura amavuta

Mu gucukura no gukora peteroli, hydroxyethyl cellulose ifite umuvuduko mwinshi ikoreshwa cyane cyane nk'umuvuduko wo gukora ibinyobwa byo kurangiza no kurangiza ibinyobwa. hydroxyethyl cellulose ifite umuvuduko muto ikoreshwa nk'umuvuduko wo gutakaza amazi. Mu byondo bitandukanye bikenewe mu gucukura, kurangiza, gusima no gucikamo ibice, hydroxyethyl cellulose ikoreshwa nk'umuvuduko wo gukurura kugira ngo ibyondo bigire umuvuduko mwiza kandi bihamye. Mu gucukura, ubushobozi bwo gutwara ibyondo bushobora kunozwa, kandi igihe cyo gukora cy'agace k'imashini gishobora kongerwa. Mu byondo byo kurangiza no gusima bifite umuvuduko muto, hydroxyethyl cellulose igabanya umuvuduko w'amazi ishobora kubuza amazi menshi kwinjira mu gishishwa cy'amavuta ava mu gishishwa no kunoza ubushobozi bwo gukora icyo gishishwa cy'amavuta.

4.Inganda zikora imiti ya buri munsi

Hydroxyethyl cellulose ni igikoresho cyiza cyo gushushanya, gufunga, gukurura, gusiga neza no gukwirakwiza mu shampoo, spray y'umusatsi, neutralizers, conditioner y'umusatsi n'amavuta yo kwisiga; mu ifu y'isabune. Medium ni igikoresho cyo kongera gushyiramo umwanda. Hydroxyethyl cellulose ishonga vuba iyo hari ubushyuhe bwinshi, ibi bikaba bishobora kwihutisha igikorwa no kunoza imikorere myiza y'umusaruro. Ikigaragara ku isabune irimo hydroxyethyl cellulose ni uko ishobora kunoza uburyo imyenda itunganywa neza kandi ikagira ubuziranenge.

Inyubako ya 5

Hydroxyethyl cellulose ishobora gukoreshwa mu bwubatsi nk'imvange ya sima, sima nshya ivanze, plaster ya gypsum cyangwa izindi sima, nibindi, kugira ngo igumane amazi mu gihe cy'ubwubatsi mbere yuko ikomera kandi ikomera. Uretse kunoza uburyo amazi abikwa mu bwubatsi, hydroxyethyl cellulose ishobora no kongera igihe cyo gukosora no gufungura sima cyangwa sima. Ishobora kugabanya uruhu, kunyerera no kugwa. Ibi bishobora kunoza imikorere y'ubwubatsi, kongera imikorere myiza, kuzigama igihe, kandi icyarimwe bikongera ubushobozi bwo kongera umuvuduko wa sima, bityo bikagabanya ibikoresho fatizo.

6 Ubuhinzi

Hydroxyethyl cellulose ikoreshwa mu gushonga no mu gutera imiti yica udukoko, nk'ikintu gikomeza imiti cyangwa imiti itera imiti. Ishobora kugabanya uburyo umuti utemba kandi igafata neza ku buso bw'ikimera, bityo ikongera ingaruka zo gutera imiti ku biti. Hydroxyethyl cellulose ishobora kandi gukoreshwa nk'ikintu gitera imiti mu gusiga imbuto; nk'ikintu gifunga kandi gitera imiti mu kongera gukoresha amababi y'itabi.

7 Impapuro n'iwino

Hydroxyethyl cellulose ishobora gukoreshwa nk'ikintu gipima ingano ku mpapuro no ku ikarito, ndetse n'ikintu gikomeza no gufunga wino ishingiye ku mazi. Mu gukora impapuro, imiterere myiza ya hydroxyethyl cellulose irimo guhuza ishinya nyinshi, resins n'imyunyu ngugu, ifuro rike, ogisijeni nke ikoreshwa n'ubushobozi bwo gukora firime yoroshye. Iyi firime ifite ubushobozi buke bwo kwinjira ku buso kandi irabagirana cyane, kandi ishobora no kugabanya ikiguzi. Impapuro zometseho hydroxyethyl cellulose zishobora gukoreshwa mu gucapa amashusho meza. Mu gukora wino ishingiye ku mazi, wino ishingiye ku mazi irakomera na hydroxyethyl cellulose yumuka vuba, ikagira amabara meza kandi ntitera gufatana.

Igitambaro 8

Ishobora gukoreshwa nk'igikoresho cyo gufatanya no gupima ingano mu gucapa no gusiga irangi ku myenda no gusiga irangi rya latex; ikintu cyo gukurura ibikoresho inyuma ya tapi. Mu byuma by'ikirahure, ishobora gukoreshwa nk'igikoresho cyo gukora no gusiga; mu ruhu, ishobora gukoreshwa nk'igikoresho cyo guhindura no gusiga. Itanga ubwoko bwinshi bw'ubukorikori kuri izi myenda cyangwa kole, ituma irangi rirushaho kuba rimwe kandi ryihuse, kandi ishobora kunoza uburyo icapiro n'irangi birushaho kuba byiza.

9 Ibumba

Ishobora gukoreshwa mu gukora kole ikomeye cyane ikoreshwa mu byuma bya ceramic.

10.umuti w'amenyo

Ishobora gukoreshwa nk'umuti wongera ubushyuhe mu gukora amenyo.

Gupfunyika: 

Imifuka y'impapuro ifite ibiro 25 imbere irimo imifuka ya PE.
