Gushyira mu bikorwa hydroxyyethyl selile muri coatings

HydroxyAythyl Cellulose (HEC) ni ukomoka kuri churigisi ya selile bikoreshwa cyane mu nganda zo gupfuka kandi bifite imirimo myinshi nko kubyimba, gutuza, kugumana amazi, no gutaha. Birakunzwe cyane mumavuta ashingiye kumazi kuko umubiri wacyo udasanzwe wumubiri na shimi ushobora kunoza cyane imikorere yikintu.

1. Ingaruka zijimye
Imwe mukoresha igaragara ya hydroxyyethyl selile muri coatings ni ibintu byiza cyane bibyimbye. Nkikigo cya polymer gifata amazi, HEC irashobora gukuramo amazi muri sisitemu yo kuroga kandi igakora igisubizo gihamye, bityo yongera vicosiya. Ibi ntibifasha gusa kunoza imikorere yimikorere, ariko kandi yemerera irangi kubungabunga urwego rwiza kandi ruhagaritse mugihe cyubwubatsi, kugabanya kugabanuka. Imbaraga zubushobozi bwayo bwimbitse rifitanye isano rya bugufi nibintu nka uburemere bwa molecular nurwego rwo gusimbuza. Ibicuruzwa bitandukanye bya HEC birashobora guhitamo imiterere ikwiye ukurikije ibikenewe byihariye.

2. Imikorere yo kugumana amazi
Ibikoresho by'amazi ya hec bituma bigira akamaro cyane mu bice, cyane cyane mu matwi yubatswe no gutara. Mugihe cyubwubatsi bwirashe, amazi arashira vuba, ashobora kuganisha kubibazo nko gutinda kwa firime yindege kandi yagabanutse. HEC irashobora gukuramo ubushuhe kandi ikatinda guhumeka, bigatuma ipfundo rikomeza ubuswa bukwiye kandi tugarinda ibibazo byiza biterwa no kubura amazi byihuse mugihe cyo kubaka. Iyi mikorere ni ngombwa cyane mubidukikije hamwe nibidukikije byumye.

3. Gutura no kugenzura no kugenzurwa
HEC ifite kandi ubushobozi buhebuje bwo guhindura abantu muri sisitemu yo kwihitiramo. Irashobora guhindura thixotropy ya pariki kugirango igumane viscosi yisumbuye mugihe irangi rihagaze kandi rikarinda gutura hamwe numwuka; Mugihe mugihe cyo kubaka, birashobora kugabanya viscosiya kandi bizangerera amazi kandi byuzura irangi. Iyi thixotropy ifite akamaro gakomeye kugirango atezimbere ububiko bwo kubika no gukora imirimo. Muri icyo gihe, HEC itezimbere cyane imbaraga zo guturana hakonje, kubyemerera gukomeza umutekano mwiza munsi yubushyuhe bwo hasi no gukumira ifatwa cyangwa gucika intege.

4. Ingaruka zo kumera Emulizer
Mu mashusho ya emulsion nka latex irangi, hydroxyyeryl selile kandi ikora nk'intandaro ya emulizer. HEC irashobora guhuza neza icyiciro cyarambitse hamwe nigiciro kama kugirango ikore sisitemu ihamye kandi ikumira ibipimo bya Emilsion cyangwa gukusanya. Mugihe kimwe, irashobora kandi kuzamura uburinganire bwirangi, yemerera pigment hamwe nuzuzanya kugirango bigabanywa cyane muburambe kugirango wirinde ibice cyangwa amabara. Ibi biteza imbere cyane isura, kubaka no kuramba byo kwingita.

5. Gutezimbere imikorere yubwubatsi
HEC irashobora kunoza cyane imikorere yo gusaba, cyane cyane koroshya kwoza cyangwa gutera. Mugihe cyo gushushanya, HEC irashobora kugabanya ibicuruzwa no gukora filime yoroheje kandi yambaye imyenda. Byongeye kandi, bigabanya gusana, byongera amarangi, kandi bigatuma imashini yishyure kandi yoroshye, bityo yongerera ubuzima rusange. Uku kunoza imikorere yubwubatsi bifite akamaro gakomeye kubibazo no gushyira mu bikorwa amabara ashingiye ku mazi.

6.. Kurwanya n'imiterere n'imikorere y'ibidukikije
Ikindi nyungu zikomeye za hydroxyyerthyl selile ni imikorere y'ibidukikije. HEC ni ko selile isanzwe ikomoka kuri biodegrafiya myiza kandi ntabwo izatera umwanda zirambye kubidukikije. Byongeye kandi, uburozi buke butuma bikoreshwa mumababi ashingiye ku mazi ari urugwiro n'ibidukikije n'umubiri w'umuntu, kubahiriza ibyatsi n'ibidukikije bisabwa mu nganda zigezweho.

Muri icyo gihe, Hec afite imiti ikomeye yimiti kandi irashobora guhuza na aside hamwe nibidukikije bya alkali, bituma byerekana guhuza neza muri sisitemu zitandukanye zo guhiga. Yaba ipaki yatinze, irangi ryubwubatsi, cyangwa amarangi ashingiye kuri peteroli, HEC ikora neza nibindi bintu bidatera ingaruka cyangwa kwangiza imikorere ya parike.

7. Ibyiringerora ibintu n'amahitamo
Mubikorwa byo kubyara, ni ngombwa cyane guhitamo hydroxyyerthyl ibicuruzwa bya selile. Uburemere bwa molekile, urwego rwo gusimbuza, guke cyane nimiterere ya HEC byose bizagira ingaruka ku ngaruka zanyuma zo gutwikira. Muri rusange, uburemere bukomeye bwa molekelar hec ifite ingaruka zikomeye, mugihe uburemere buke bwa molecular hec bukwiriye nkintandaro cyangwa ikwirakwizwa. Byongeye kandi, umuvuduko wo gusenyuka wa Hec hamwe no gukorera mu mucyo bituma bigira ingaruka ku isura no gukora imirimo yo kubaka. Kubwibyo, muburyo butandukanye bwa porogaramu, birakenewe guhitamo ibicuruzwa bikwiye bya hec ukurikije ibikenewe byihariye.

HydroxyAythyl selile irakoreshwa cyane mu nganda zo gupfuka. Kwiyongera kwayo, kugumana amazi, gutuza no gutatanya imitungo birashobora kunoza uburyo bwiza n'imikorere ya coato. Muri icyo gihe, imikorere yo kurinda ibidukikije ya Hec nayo ibivuga bijyanye n'iterambere ry'inganda zigezweho. Mu bihe biri imbere, hamwe no gutera imbere guhora cyo gutwikira ikoranabuhanga n'impinduka ku gipimo cy'isoko, ikoreshwa rya hydroxyyethyl selile muri churlilose muri coatings bizahinduka byinshi kandi byimbitse.
