Gushyira mu bikorwa hydroxyyeryl selile (hec) mu nganda zifata

1. IRIBURIRO

HydroxyAythyl Cellulose (HEC) ni ether ya selile itana yabonetse mu gufata selile kamere na Ethylene okide nyuma yo kuvura alkali. HEC ikoreshwa cyane mu nganda zifata kubera imitungo idasanzwe yumubiri na shimi, nkamazi menshi yonyine, ubushobozi bwiza bwo guhinduranya ububasha nibikorwa byo hejuru.

2. Ibiranga ishingiro rya hec

Hec ifite ibintu bikurikira bikurikira, bigatuma ibaha cyane mu nganda zo kurera:
Amazi yonyine: HEC irashobora gushonga rwose mumazi akonje kugirango akore igisubizo gisobanutse cyangwa cya microemulsion, kibafasha guhindura neza vicosiya.
Ingaruka zijimye: HEC ifite imitungo myiza yijimye kandi irashobora kongera ubukwe bwigisubizo mugihe gito, bityo ikagira imbere imikorere na filmée yimpumba.
Guhagarara gushikama: HEC irashobora guhagarika ihagarikwa no gukumira imyanda ya pigment cyangwa kuzungura mu gupfunga, bityo bigatuma uburinganire no gutuza.
Thixotropy: Hec itanga sisitemu yo gupfukirana neza thixotropy nziza, ni ukuvuga mubikorwa byimbaraga zububasha, ubushyuhe bwimiterere iragabanuka, buroroshye kubaka; Iyo imbaraga zo gufata ingufu zirekuwe, ipati yahise isubiza viscosi yumwimerere, kugabanya guseba no kumeneka.
Gurinda DOLLOID ingaruka: HEC irashobora gukora inkomoko yo kurinda kugirango irinde gusenya polymery polymery no kunoza igihangano.

3. Gushyira mu bikorwa hitagaciro

3.1 Irangi ryatinze

Gusaba hec irangi ryatinze bigaragarira cyane cyane mubahozeho, abigatanya no kugumana amazi:

Thickener: Hec irashobora kongera ubushishozi bwirangi ya latex, bityo itezimbere amazi no kubaka irangi. Muguhindura kwibanda kuri Hec, viscometike ikwiye isabwa muburyo butandukanye bwubwubatsi (nko gukaza, kuzunguruka, no gutera imbaraga) birashobora kuboneka.
Stabilizer: HEC irashobora kubuza neza imyanda hamwe nisoni mumashusho ya latex, kandi utezimbere uburinganire nububiko bwububiko.
Umukozi ugumana amazi: Hec ifite ubushuhe bwiza. Mugihe cyubwubatsi, irashobora kwirinda amazi hejuru irangi kuva kubyutsa vuba, bityo wirinze guca impinja nifu ya firime yo gusiga irangi kandi utezimbere igorofa nubuzima bwa firime irangi.

3.2 Irangi ryamazi

Mu mbuto ishingiye ku muyaga, HEC ikoreshwa cyane nk'umukozi ushinzwe kugenzura kandi ya SAG igenzura:

Kuringaniza urwego: Hec itanga amabara ashingiye kumazi aranga imitungo myiza, ifasha gukora firime imwe kandi yoroshye iyo ifunze ibiti, bigabanya ibimenyetso bya Brush hamwe na orange.

Igenzura rya SAG: Mugutezimbere thuxotropi ishingiye ku mwobo ushingiye ku mazi, HEC irashobora kugenzura neza sag y'amarangi iyo ikoreshejwe ku buso buhagaze, kunoza imikorere yubwubatsi na film nziza.

3.3 IHURIRO RY'INGENZI

Mububiko bwubwubatsi (nk'urukuta rwo hanze n'urukuta rw'imbere), HEC ifite uruhare runini nk'umunyego w'igituba, abatatanye kandi akora imyitozo ngororamubiri kandi ishyiraho film:

Thickener: Hec yongerera vicosity yo mu mateka y'ubwubatsi, bigatuma ifite imitungo myiza yo kubaka mugihe cyubatswe, ikagabanya SAG no gutonyanga, no kwemeza umubyimba n'umwenda wo gutwikira.
Gutabara: HEC irashobora gutatanya no guhagarika uduce twigipfu, kubabuza gutongana no gutura, no kunoza gutatanya no guhuriza hamwe no guhuriza hamwe.
Imfashanyo ya Filime: HEC irashobora kunoza imitungo yo gukora kuri firime yo gutwikira, itezimbere ishyirwaho no gukama film ya paye, kandi itezimbere imitungo hamwe na mashini ya firime ya barangi.

3.4 IHURIRO RIDASANZWE

Mu makota adasanzwe (nko mu mavuta yo kurwanya ruswa, gusohora umuriro, hamwe no gutura mu bushyuhe), HEC yongera ibikorwa bidasanzwe by'imikorere yacyo, igahaza, n'amashanyarazi,

Ipantaro yo kurwanya ruswa: Hec itezimbere urukwavu no guhagarikwa gushikama no guhindagurika kwagandumirwa, bifasha kuba ikoti kandi bikaba bigize urwego rwinshi.
IHURIRO RY'UMUKARA: IYI GIKORWA BY'INGENZI N'IMBERE CY'IMIKORESHEREZO YA HEC BUFASHA IHURIRO RY'INGENZI IFITE UMURIMO UFITE UBURENGANZIRA BW'INGENZI MU BIKURIKIRA
Amazu y'isuku: Hec itanga aho ihurira mu bushyuhe bwo guhagarikwa no gukorana ibikorwa, bigatuma ifuro ritangwa cyane mugihe cyo gukwirakwiza no kuzamura imiti yubushyuhe.

4. Guhitamo Hec no Gukoresha ingamba

Mugihe uhisemo no gukoresha Hec, ingingo zikurikira zigomba kwitonderwa:

Guhitamo vicosity: Hitamo amanota ya Hec Stand Subcosity ukurikije sisitemu zitandukanye zo kwisiga. Kurugero, hescosity-viccosity hec irakwiriye kwihindamo sisitemu ndende cyangwa viso ndende, mugihe heccosity hec ibereye sisitemu ifite ibintu bike cyangwa ubuyobe buke.
Uburyo bwo kongereranyo: Kugirango wirinde gushiraho ibibyimba mugihe hec yashonga mumazi, uburyo bwo kwiyongera buhoro buhoro, kandi ubushyuhe bwiyongereye cyane kandi igihe gishimishije cyongerewe mugihe cyo kuvugurura.
Guhuza: Iyo Hec ihuye nizindi nguzanyo (nko gutandukana nabatanyutse), kwitabwaho kugirango bishyuwe imikoranire yabo kugirango birinde ibibazo byo guhuza no kugira ingaruka kumikorere yimpute.

5. Iterambere rizaza

Hamwe no guteza imbere inganda zo gupfukirana, ibisabwa kugirango ukore imikorere igenda yiyongera umunsi kumunsi. Nkibikorwa byingenzi byongeraho, Hec ifite ibyifuzo byinshi. Mu bihe biri imbere, ikoreshwa rya HEC mu bice birashobora gutera imbere mu byerekezo bikurikira:

Ikirere kibisi no mu bidukikije: Gutezimbere ibicuruzwa bike-by'ubusa kugirango uhuze ibisabwa byo kurengera ibidukikije no gukenera isoko.
Guhindura imikorere: Binyuze mu guhindura imiti cyangwa guhindura umubiri, HEC ihabwa imitungo mishya, nka antibacterial, antimarling, kwisukura, nibindi.
Amavuta menshi: Gutezimbere ibicuruzwa bikwiranye no guhuza imikorere yo hejuru kugirango ubone ibintu byihariye byo kubaka imirima, imodoka, amato, nibindi
Hydroxyyeryl selile (HEC), nkuko inyongeramurwa rusange, igira uruhare runini mu nganda zo kurema. Ubwinshi bwayo buhebuje, guhagarikwa, Thixotropic ingaruka za Colloid zikoreshwa cyane mu gishushanyo cyatinze, amarangi ashingiye ku gihuru, amarangi ashingiye ku muyaga, amarangi ashingiye ku bubiko. Hamwe niterambere rihoraho ryinganda zikora, ibyifuzo bya HEC bizagukwirakwiza. Mugihe kizaza, mugutezimbere imikorere y'ibidukikije n'imikorere mikorere ya Hec, agaciro ka porogaramu mu bijyanye no kurera bizarushaho kwiyongera.
