Guhitamo neza hydroxyethyl selulose (HEC) kubyimbye kugirango irangi rya latex bikubiyemo gusuzuma ibintu bitandukanye, harimo imiterere ya rheologiya yifuzwa, guhuza nibindi bice bigize irangi, nibisabwa byihariye mubisabwa. Aka gatabo gakubiyemo ibintu byose bizagufasha gufata icyemezo cyuzuye cyo guhitamo umubyimba mwiza wa HEC kugirango ushushanye irangi rya latex.
1. Intangiriro kuri Latex Irangi Irangi:
1.1 Ibisabwa Rheologiya:
Irangi rya Latex rikeneye guhindura imvugo kugirango igere kubyo wifuza bihamye, bihamye, hamwe nibisabwa. HEC ni amahitamo asanzwe bitewe nubushobozi bwayo mukubyimba amazi ashingiye.
1.2 Akamaro ko kubyimba:
Ibikoresho byibyimbye byongera irangi ryijimye, birinda kugabanuka, kunoza brush / roller, no gutanga ihagarikwa ryiza ryibintu byuzuza.
2. Gusobanukirwa Hydroxyethyl Cellulose (HEC):
2.1 Imiterere yimiti nibyiza:
HEC ni polymer yamashanyarazi ikomoka kuri selile. Imiterere yacyo idasanzwe itanga umubyimba no gutuza kurangi irangi.
2.2 Ibyiciro bya HEC:
Ibyiciro bitandukanye bya HEC birahari, bitandukanye muburemere bwa molekuline no kurwego rwo gusimbuza. Uburemere buke bwa molekuline no kuyisimbuza birashobora gutuma umusaruro wiyongera.
3. Ibintu bigira uruhare mu guhitamo HEC:
3.1 Irangi rya Latex:
Reba muri rusange, harimo ubwoko bwa latex, pigment, ibyuzuza, ninyongeramusaruro, kugirango umenye guhuza HEC yahisemo.
3.2 Umwirondoro wifuzwa:
Sobanura ibyifuzo byihariye bya rheologiya kubirangi byawe bya latex, nko kunanagura umusatsi, kuringaniza, no kurwanya spatter.
4. Ibyingenzi byingenzi muguhitamo HEC:
4.1 Ubusabane:
Hitamo icyiciro cya HEC gitanga ubwiza bwifuzwa muburyo bwa nyuma bwo gusiga irangi. Kora ibipimo bya viscosity mugihe gikurikizwa.
4.2 Kwiyogosheshaimyitwarire:
Suzuma imyitwarire yogosha, igira uruhare muburyo bworoshye bwo gushyira mu bikorwa, kuringaniza, no kubaka film.
5.Kudahuza no gushikama:
5.1 Guhuza Latex:
Menya neza ko HEC ihujwe na latex polymer kugirango wirinde ibibazo nko gutandukanya icyiciro cyangwa gutakaza umutekano.
5.2 pH Ibyiyumvo:
Reba pH ibyiyumvo bya HEC n'ingaruka zabyo kumutekano. Hitamo urwego rukwiranye na pH urwego rwa latex yawe.
6.Ubuhanga bwo gusaba:
6.1 Gusaba Brush na Roller Porogaramu:
Niba brush na roller ikoreshwa nibisanzwe, hitamo urwego rwa HEC rutanga brush / roller gukurura no kurwanya spatter.
6.2 Gusaba Gusaba:
Kuri spray progaramu, hitamo urwego rwa HEC rugumana ituze mugihe cya atomisation kandi ikemeza no gutwikira.
7. Kwipimisha no kugenzura ubuziranenge:
7.1 Isuzuma rya Laboratoire:
Kora ibizamini bya laboratoire neza kugirango usuzume imikorere yamanota atandukanye ya HEC mubihe bigereranya isi-nyayo.
7.2 Ibigeragezo byo mu murima:
Kora ibizamini byo murwego kugirango wemeze ibyavuye muri laboratoire kandi urebe imikorere ya HEC yatoranijwe muburyo bwo gusiga amarangi.
8.Ibitekerezo byo kugenzura no kubungabunga ibidukikije:
8.1 Kubahiriza amabwiriza:
Menya neza ko HEC yatoranijwe yujuje ibyangombwa bisabwa kugira ngo usige amarangi, urebye ibintu nka VOC (ibinyabuzima bihindagurika).
8.2 Ingaruka ku bidukikije:
Suzuma ingaruka ku bidukikije bya HEC hanyuma uhitemo amanota hamwe ningaruka nke z’ibidukikije.
9. Ibitekerezo byubucuruzi:
9.1 Igiciro:
Suzuma ikiguzi-cyiza cyamanota atandukanye ya HEC, urebye imikorere n'ingaruka zabyo muri rusange.
9.2 Gutanga Urunigi no Kuboneka:
Reba kuboneka no kwizerwa kumurongo wo gutanga HEC yatoranijwe, urebe neza ireme.
10.Umwanzuro:
guhitamo iburyo bwa HEC kubyibara rya latex bikubiyemo gusuzuma byimazeyo ibisabwa bya rheologiya, guhuza, tekinoroji yo gukoresha, hamwe nibitekerezo. Urebye ibi bintu, urashobora guhitamo icyiciro cya HEC cyujuje ibyifuzo bikenewe kugirango ushushanye irangi rya latex, urebe imikorere ihamye hamwe nubuziranenge mubihe bitandukanye byo gusaba.
