Ukusetyenziswa kwe-hydroxythyl seluplose (hec) kwishishini lemali

1. Intshayelelo

I-HydroxyEtheetheethy yeselutase (Hec) i-Inseulose Ether ifunyenwe ngokuphendula ngokuphendula ngendalo kunye ne-Ethylene oxide emva konyango lwaseAlkali. I-HEC isetyenziswe ngokubanzi kwimveliso yempahla ngenxa yepropathi yayo eyodwa yomzimba kunye neekhemikhali, ezinje ngomhlaba ophezulu wamanzi, uhlengahlengiso lohlengahlengiso oluhle kunye nomsebenzi womphezulu.

2. Iimpawu ezisisiseko ze-hec

I-HEC inezi mpawu zibalulekileyo zilandelayo, zenza ukuba ibe yinto ebalulekileyo kwishishini lempahla:
Ukuzola kwamanzi: I-HEC inokutshitshiswa ngokupheleleyo kumanzi abandayo ukwenza isisombululo esicacileyo okanye se-microulsion, esenza ukuba ilungelelanise i-viscosity ye-viscosity.
Isiphumo sokuqaqamba: I-HEC inepropathi egqwesileyo kwaye inokunyusa ukubonwa kwesisombululo kwindawo ephantsi, ngaloo ndlela iphucule ukusebenza kunye neempawu zefilimu zokudibana.
Ukunqunyanyiswa kozinzo: UHec unokuzinzisa ukunqunyanyiswa kwaye kuthintele i-sediment ye-pigment okanye i-firlers kwi-coyid, ngaloo ndlela iphucule ukufana kunye nokuzinza.
I-ThixotRopy: Hec inika inkqubo yokudibana kwe-Thixotropy, oko kukuthi, phantsi kwesenzo samandla eShear, i-viscosity yeCoid, ilungele ukwakhiwa; Xa umqobo weshera khulu ukhululwe, ukungqengqeleka ngokukhawuleza ngokukhawuleza, ukunciphisa ukuqhwanyaza nokutshiza.
Isiphumo sokukhusela i-colloid: hec inokwenza iicolloids ezikhuselayo ukuthintela ukubhalwa kwee-polymers ze-Latex kwaye kuphuculwe ukuzinza kwengqumbo.

3. Ukusetyenziswa okuthile kwe-hec kwingubo

3.1 Ipeyinti ye-testx

Ukusetyenziswa kwe-hec kwipeyinti ye-latex kuboniswa ikakhulu kwii-thi chuishers, izilotha kunye nabagcini bamanzi:

I-tickener: hec inokunyusa kakhulu i-viscofity yepeyinti ye-Latex, ngaloo ndlela iphucule ulwelo nolwakhiwo lwepeyinti. Ngokuhlengahlengiswa koxinzelelo lwe-HEC, uVenkile olufanelekileyo olufunekayo ngeendlela ezahlukeneyo zokwakha (njengokubrasha, ukuntywila, kunye nokutshiza) kunokufunyanwa.
I-Stbiblizer: I-HEC inokuthintela ngokufanelekileyo i-sediment ye-pigments kunye neefilitha kwiipeyinti ze-Latex, kunye nokuphucula ukufana nokugcinwa kokugcinwa kwepeyinti.
Iarhente yokugcina amanzi: i-hec inyanzelekile. Ngexesha lenkqubo yokwakha, inokunqanda amanzi kwindawo yokupeyinta ukusuka ekufundeni ngokukhawuleza, ngaloo ndlela kukuthintela ukuqhekeza kunye nemifanekiso yefilimu yepeyinti kunye nokuphucula ifilimu yepeyinti.

3.2 Ipeyinti yenkuni esekwe emanzini

Kwipende esekwe emanzini, i-HEC isetyenziswa ikakhulu njengearhente yearhente kunye nearhente yolawulo lwe-SAG:

Iarhente yokuQalisa: I-HEC inika iinkuni ezisekwe emanzini, ezinceda ekwenzeni i-filimu ye-pilisi kunye nepeyinti egudileyo xa ithatha indawo yokuthintela umphezulu weenkuni, ukunciphisa uphawu lwegazi kunye ne-orenji.

Ulawulo lwe-SAG: ngokuphucula i-Thupotropy yepeyinti esekwe emanzini, i-HEC inokulawula ngempumelelo i-SAG yepeyinti xa isetyenziswa kumgangatho wokwakha, ukuphucula umgangatho wokwakha kunye nepeyinti yefilimu.

I-3.3 ye-Offatings

Kwindlela yokuyila yoyilo (enjengeengubo zangaphandle zangaphandle kunye nengubo yangaphakathi yodonga), i-HEC idlala indima ebalulekileyo njenge-thi chopokener, isisasazo kunye noncedo lokwenza ifilimu:

I-Thickener: I-HEC inyusa i-viscosity yewotshi yoyilo, esenza ineepropathi ezifanelekileyo zokwakha ngexesha lokwakha, ukunciphisa i-SAG kwaye ilahle, kwaye iqinisekisa ubukhulu becala.
Ukusasazeka: I-hec inokusasaza kwaye ikwazi ukuzinzisa amasuntswana, ukubathintela ekuphelisweni nasekuhlalukeni, kwaye uphucule ukusasazeka kunye nokufakwa kwe-diadermity.
Uncedo lokwenza ifilimu: I-HEC inokuphucula iipropathi zokwenza ifilimu zokudibana, ukukhuthaza ukumiliselwa kunye nokomisa ifilimu yepeyinti, kunye nokuphucula iipropathi zoomatshini kunye nokuqhekeka kwefilimu yepeyinti.

3.4 Iingubo ezikhethekileyo

Kumanye amagqume ekhethekileyo (ezinjengeengubo ezithambileyo zokunyanzelwa, impahla yokuhlawula umlilo, kunye ne-inshurensi yokufakelwa kwe-thermal), i-HEC iphucula iimfuno zentsebenzo ezizodwa zendlela yokuthuka, ukuzinza kwayo:

I-Anti-Corrosion CoatIngs: I-HEC iphucula ukuthandwa kunye nokunqunyanyiswa kokuzimela kwengubo yokulwa i-anti-corasion, enceda ekubekweni kwengubo yokunga ngokulinganayo kwaye yenze ungqilelo oluninzi olude.
Ingubo yokuhlawula umlilo: I-viscofity ephezulu kunye neempawu zokwenza ifilimu ze-HEC ukunceda ukuhlawula i-HECIDS yendlela yokukhusela kubushushu obuphakamileyo kunye nokuphucula ukunyangwa komlilo.
Imali yokufakelwa kwe-Hermal inika i-intermating thessels elungileyo yokuzinquma kunye nokusebenza, ukuvumela ukuba umbilini usasazwe ngokulinganayo ngexesha lenkqubo yokufunyanwa kwengozi kunye nokuphucula ifuthe lokutshekisha.

I-4. Ukukhetha i-hec kunye nokusebenzisa izilumkiso

Xa ukhetha kwaye usebenzisa i-hec, la manqaku alandelayo makaqatshelwe:

Ukukhetha i-Viscofity: Khetha iBanga elifanelekileyo le-HEC le-hec ngokwenkqubo ezahlukeneyo zokuhamba. Umzekelo, i-hec ephezulu ye-hec ilungele iinkqubo zokuthinta kunye nomxholo omkhulu oqinileyo okanye i-viscosity ephezulu, ngelixa i-hec ye-hec ephantsi ilungele iinkqubo ezinomxholo ophantsi okanye i-viscofity ephantsi.
Indlela yongezelelo: Ukwenzela ukuthintela ukwenziwa kweendlela xa i-HCC ichithwe emanzini, indlela yokudibanisa kancinci kwaye ishukumisa itshatisiwe, kwaye ixesha lobushushu lisongele ngokufanelekileyo ngexesha lenkqubo yokupheliswa.

I-5. Imeko yophuhliso lwexesha elizayo

Ngokuphuhliswa okuqhubekayo kwemveliso ehlekisayo, iimfuno zokusebenza okuphathekayo ziyanda imihla ngemihla. Njengesonga ibalulekileyo esebenzayo, i-HEC inamathuba okusebenza. Kwixa elizayo, ukusetyenziswa kwe-hec kwi-carengs kunokuphuhliswa kwezi zikhokelo zilandelayo:

Ukukhuliswa eluhlaza kunye nokusiNgqongileyo: Ukuphuhliswa kwe-VOC ephantsi, i-HOC engaphantsi ye-HEC yokufezekisa iimfuno zoKhuseleko lweNkcubeko kunye neBango leNtengiso.
Ukulungiswa kokuSebenza: Ngokuguqulwa kwekhemikhali okanye ukulungiswa komzimba, i-HEC inikwa iipropathi ezintsha zomsebenzi, ezinje ngokuchasene ne-antibactering, i-anting, ukuzicoca, njl njl.
I-POARING ERODS: Phuhlisa iimveliso zehekc ezifanelekileyo kwiimali ezisebenza kakhulu zokuhlangabezana neemfuno ezizodwa zokusebenza, iimoto, iinqanawa, njl njl.
I-HYDROXYETHTHleTELL seluplose (Hec), njengokutshixiza kwezinto ezininzi, idlala indima ebalulekileyo kwishishini lempahla. Ukuqaqanjelwa kwayo ngokusemagqabini, ukunqunyanyiswa, i-Thizotropic kunye ne-TIXLODPIC ye-Colloid yenza ukuba i-HEC isetyenziswe ngokubanzi kwipeyinti ye-Lacex, iipeyinti ezisekwe emanzini, iipayikhi zenkuni kunye neengubo ezizodwa. Ngokuphuhliswa okuqhubekayo kwemveliso yempahla, ithemba lesicelo le-hec liya kubanzi. Kwixesha elizayo, ngokuphucula ukusebenza kwendalo kunye neempawu ezisebenzayo ze-HeC, ixabiso layo lesicelo kwiingubo ziya kuphuculwa ngakumbi.
