Imikorere nogukoresha hydroxyethyl selulose

Ibyiza bya Hydroxyethyl Cellulose

Ibintu nyamukuru biranga hydroxyethyl selulose ni uko ibora mumazi akonje ndetse namazi ashyushye, kandi ikaba idafite imiterere ya gel. Ifite intera nini yo gusimbuza, gukomera no kwiyegeranya, guhagarara neza k'ubushyuhe (munsi ya 140 ° C), kandi ntabwo itanga gelatine mubihe bya aside. imvura. Hydroxyethyl selulose yumuti irashobora gukora firime ibonerana, kandi ifite ibiranga ubwoko butari ionic budahuza na ion kandi bufite ubwuzuzanye bwiza.

Temperature Ubushyuhe bwo hejuru hamwe no gukomera kwamazi: Ugereranije na methyl selulose (MC) ikemuka gusa mumazi akonje, hydroxyethyl selulose irashobora gushonga mumazi ashyushye cyangwa mumazi akonje, kandi ntigwa kugwa mubushyuhe bwinshi cyangwa kubira, bigatuma ifite intera nini ya solubilité hamwe nibiranga viscosity, hamwe nibintu bitari thermogelling.

Erance Kwihanganira umunyu: Kubera ko itari ionic, irashobora kubana hamwe nandi moko menshi yandi mavuta ya elegitoronike ashonga, surfactants, nu munyu. Kubwibyo, ugereranije na ionic carboxymethyl selulose (CMC), hydroxyethyl selile ifite imbaraga zo kurwanya umunyu.

Ret Kubika amazi, kuringaniza, no gukora firime: ubushobozi bwayo bwo kubika amazi bwikubye kabiri ubw'ubwa methyl selulose, kandi bufite uburyo bwiza bwo gutembera neza, ibintu byiza byerekana firime, kugenzura gutakaza amazi, kutabeshya, no guhuza ibitsina bikingira.

Gukoresha hydroxyethyl selulose

Hydroxyethyl selulose nigicuruzwa kitari ionic cyamazi ya elegitoronike ya ether, ikoreshwa cyane mububiko bwububiko, peteroli, polymer polymerisation, ubuvuzi, imikoreshereze ya buri munsi, impapuro na wino, imyenda, ububumbyi, ubwubatsi, ubuhinzi nizindi nganda. Ifite imirimo yo kubyimba, guhuza, kwigana, gukwirakwiza no gutuza, kandi irashobora kubungabunga amazi, gukora firime no gutanga ingaruka zo gukingira. Irashobora gushonga byoroshye mumazi akonje namazi ashyushye, kandi irashobora gutanga igisubizo hamwe nubwinshi bwubwiza. Niterambere mumyaka yashize. Imwe muma selile yihuta.

1. Irangi rya Latex

Hydroxyethyl selulose niyo ikoreshwa cyane mubyimbye mumarangi ya latex. Usibye kubyimba irangi rya latex, irashobora kandi kwigana, gutatanya, gutuza no kugumana amazi. Irangwa ningaruka zidasanzwe zo kubyimba, iterambere ryiza ryamabara, gukora firime no kubika neza. Hydroxyethyl selile ni inkomoko ya ionic selulose ishobora gukoreshwa muburyo bugari bwa pH. Ifite guhuza neza nibindi bikoresho mubice (nka pigment, inyongeramusaruro, uwuzuza umunyu). Ipitingi yuzuye hamwe na hydroxyethyl selulose ifite rheologiya nziza kubiciro bitandukanye byogosha kandi ni pseudoplastique. Uburyo bwubwubatsi nka brush coating, roller coating and spray coating irashobora gukoreshwa. Ubwubatsi bwiza, ntabwo byoroshye gutonyanga, sag no kumenagura, hamwe nibintu byiza byo kuringaniza.

2. Polymerisation

Hydroxyethyl selulose ifite imirimo yo gukwirakwiza, kwigana, guhagarika no guhagarika muri polymerisation cyangwa copolymerisation yibigize insimburangingo, kandi birashobora gukoreshwa nka colloid ikingira. Irangwa nubushobozi bukomeye bwo gukwirakwiza, uduce duto duto "firime", ingano nziza yingirakamaro, imiterere yingingo imwe, ubwoko bworoshye, amazi meza, ibicuruzwa byinshi bibonerana kandi bitunganijwe byoroshye. Kubera ko hydroxyethyl selulose ishobora gushonga mumazi akonje namazi ashyushye, kandi ikaba idafite aho ihurira nubushyuhe, irakwiriye muburyo butandukanye bwa polymerisiyasi.

Ibintu byingenzi bifatika kugirango ukore iperereza ku bwiza bwikwirakwizwa ni ubuso (cyangwa intera) impagarara, imbaraga zidasanzwe hamwe nubushyuhe bwa gelation yumuti wacyo wamazi. Iyi miterere ya hydroxyethyl selulose ikwiranye na polymerisation cyangwa copolymerisation ya sintetike. Hydroxyethyl selulose ifite ubwuzuzanye bwiza nandi mazi ya elegitoronike ya elegitoronike na PVA. Sisitemu igizwe rero irashobora kubona ingaruka zuzuye zo kwigira kubandi. Ibicuruzwa bya resin bikozwe nyuma yo guteranya ntabwo bifite ireme ryiza gusa, ahubwo binagabanya gutakaza ibintu.

3. Gucukura amavuta

Mu gucukura amavuta no kuyibyaza umusaruro, hydroxyethyl selulose ikoreshwa cyane cyane nkibyimbye kugirango amazi arangire kandi arangize amazi. Hydroxyethyl selulose nkeya ya viscosity ikoreshwa nkigabanuka ryamazi. Mu byondo bitandukanye bisabwa mu gucukura, kurangiza neza, gukora sima no kuvunika, hydroxyethyl selulose ikoreshwa nkibyimbye kugirango ibone amazi meza kandi ituze neza. Mugihe cyo gucukura, irashobora kunoza ubushobozi bwo gutwara umusenyi wibyondo kandi ikongerera igihe cyumurimo wa biti. Mugihe gito cyo kurangiza icyiciro cya flux hamwe na sima ya sima, gutakaza amazi meza kugabanya imikorere ya hydroxyethyl selulose irashobora kubuza amazi menshi kwinjira murwego rwamavuta avuye mucyondo, kandi birashobora kuzamura ubushobozi bwumusaruro wamavuta.

4. Imiti ya buri munsi

Hydroxyethyl selulose nigikorwa cyiza cyo gukora firime, guhuza, kubyimbye, stabilisateur no gukwirakwiza muri shampo, imisatsi yimisatsi, kutabogama, gutunganya imisatsi no kwisiga; mu gukaraba ifu Nibikoresho byo kugarura ubutaka. Hydroxyethyl selulose ishonga vuba ku bushyuhe bwinshi, bushobora kwihutisha umusaruro no kunoza umusaruro. Ikintu kigaragara cyimyenda irimo hydroxyethyl selulose ni uko ishobora kunoza ubwiza nubudodo bwimyenda.

5. Ubwubatsi

Hydroxyethyl selulose irashobora gukoreshwa mubicuruzwa byubwubatsi nko kuvanga beto, minisiteri nshya, plaque gypsumu cyangwa izindi sima, nibindi, kugirango bigumane amazi mugihe cyo kubaka mbere yo gushiraho no gukomera. Usibye kunoza uburyo bwo gufata amazi yibicuruzwa byubaka, hydroxyethyl selulose inongerera ubugororangingo nigihe cyo gufungura plaster cyangwa mastique. Irashobora kugabanya uruhu, kunyerera no kugabanuka. Rero, imikorere yubwubatsi irashobora kunozwa, imikorere yakazi irashobora kwiyongera, kandi umwanya urashobora gukizwa. Muri icyo gihe, umuvuduko wo kwagura ubushobozi bwa stucco urashobora kunozwa, bityo ukazigama ibikoresho bibisi.

6. Ubuhinzi

Hydroxyethyl selulose ikoreshwa mugutegura imiti yica udukoko no guhagarika, nkikibyimbye cyo gutera imiti cyangwa guhagarika. Irashobora kugabanya umuvuduko wimiti kandi ikayihuza cyane namababi yibimera, bityo bikongera ingaruka zo gutera amababi. Hydroxyethyl selulose irashobora kandi gukoreshwa nkigikoresho cyo gukora firime mubikoresho byo gutera imbuto; nk'umushinga uhuza kandi ukora firime mugutunganya amababi y'itabi.

7. Gukora impapuro no gucapa wino

Hydroxyethyl selulose irashobora gukoreshwa nkigikoresho kinini cyimpapuro nimbaho ​​kandi nkigikoresho cyo kubyimba no guhagarika inkwa zishingiye kumazi. Mubikorwa byo gukora impapuro, ibintu bisumba byose bya hydroxyethyl selulose harimo guhuza amenyo menshi, resin hamwe nu munyu wa organic organique, ifuro rito, gukoresha ogisijeni nkeya hamwe nubushobozi bwo gukora firime nziza. Filime ifite ubushobozi buke bwo hejuru hamwe nuburabyo bwinshi, bushobora no kugabanya ibiciro. Impapuro zingana na hydroxyethyl selulose, zishobora gukoreshwa mugucapa amashusho meza. Mugukora wino ishingiye kumazi, wino ishingiye kumazi yuzuye hamwe na hydroxyethyl selulose yumye vuba, ifite amabara meza, kandi ntabwo itera gukomera.

8. Imyenda

Irashobora gukoreshwa nka binder na sizing agent mugucapa imyenda no gusiga amarangi hamwe na latx irangi; nkikibyimbye cyo gupima ibikoresho inyuma yigitambara. Muri fibre yibirahure, ikoreshwa nkibikoresho bikora na binder; muri paste y'uruhu, irashobora gukoreshwa nka modifier na binder. Tanga ubunini bwagutse kuri iyi myenda cyangwa ibifatika, kora igifuniko kimwe kandi cyihuse, kandi unoze neza gucapa no gusiga irangi.

9. Ceramics

Irashobora gukoreshwa mugutegura imbaraga-zihuza imbaraga zubutaka.

10. Amenyo

Irashobora gukoreshwa nkibyimbye mugukora amenyo.
