Cellulose ether ni ionic igice cya sintetike yo hejuru ya molekile ya polymer, ikabura amazi kandi igashonga. Ifite ingaruka zitandukanye mubikorwa bitandukanye. Kurugero, mubikoresho byubaka imiti, bifite ingaruka zikurikira:
Umukozi ugumana amazi
Ink Inkoko
Gukunda
FormationFilime
⑤ Binder
Mu nganda za polyvinyl chloride, ni emulisiferi kandi ikwirakwiza; mu nganda zimiti, ni binder kandi itinda kandi igenzurwa nibikoresho byo kurekura, nibindi. Kubera ko selile ifite ingaruka zitandukanye zingirakamaro, kuyikoresha Umwanya nawo ni mwinshi cyane. Ibikurikira, nzibanda kumikoreshereze n'imikorere ya selile ether mubikoresho bitandukanye byubaka.
1. Mu irangi rya latex
Mu nganda zo gusiga amarangi ya latex, guhitamo hydroxyethyl selulose, ibisobanuro rusange byubwiza bungana ni 30000-50000cps, bihuye nibisobanuro bya HBR250, kandi dosiye ikoreshwa muri rusange ni 1.5 ‰ -2 ‰. Igikorwa nyamukuru cya hydroxyethyl mumarangi ya latex nukubyimbye, gukumira gelation ya pigment, gufasha gutatanya pigment, gutuza kwa latex, no kongera ububobere bwibigize, bigira uruhare mubikorwa byo kuringaniza ibyubaka: Hydroxyethyl selulose iroroshye gukoresha. Irashobora gushonga mumazi akonje namazi ashyushye, kandi ntabwo ihindurwa nagaciro ka pH. Irashobora gukoreshwa neza hagati ya PI agaciro 2 na 12. Uburyo bwo gukoresha nuburyo bukurikira:
I. Ongeraho muburyo butaziguye
Kuri ubu buryo, hydroxyethyl selulose yatinze ubwoko bugomba gutoranywa, kandi hydroxyethyl selulose hamwe nigihe cyo kumara iminota irenga 30 ikoreshwa. Intambwe nizi zikurikira: ① Shyira umubare munini wamazi meza muri kontineri ifite ibikoresho byogosha cyane ② Tangira kubyutsa ubudahwema kumuvuduko muke, kandi icyarimwe wongere buhoro buhoro itsinda rya hydroxyethyl mubisubizo bingana ③Komeza kubyutsa kugeza ibikoresho byose bya granular byashizwemo dd Ongeraho izindi nyongeramusaruro ninyongera shingiro, nibindi.
Ⅱ. Bifite inzoga za nyina kugirango zikoreshwe nyuma
Ubu buryo burashobora guhitamo ubwoko bwihuse, kandi bufite anti-mildew selile. Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kongerwaho muburyo butaziguye. Uburyo bwo kwitegura ni kimwe nintambwe ①-④.
Ⅲ. Kora igikoma kugirango ukoreshwe nyuma
Kubera ko ibishishwa kama ari ibishishwa bikennye (bidashobora gushonga) kuri hydroxyethyl, iyi mashanyarazi irashobora gukoreshwa mugukora poroje. Amashanyarazi akoreshwa cyane ni amavuta kama mumavuta ya latx, nka Ethylene glycol, propylene glycol, hamwe nogukora firime (nka diethylene glycol butyl acetate). Porridge hydroxyethyl selulose irashobora kongerwaho muburyo butaziguye. Komeza kubyutsa kugeza bishonge burundu.
Icya kabiri, murukuta gusiba putty
Kugeza ubu, mu mijyi myinshi yo mu gihugu cyanjye, ibidukikije byangiza amazi kandi byangiza ibidukikije byangiza ibidukikije. Ikorwa na acetal reaction ya vinyl alcool na formaldehyde. Kubwibyo, ibi bikoresho bigenda bikurwaho buhoro buhoro nabantu, kandi ibicuruzwa bya selile ya selile ikoreshwa mugusimbuza ibi bikoresho. Nukuvuga ko, mugutezimbere ibikoresho byubaka bitangiza ibidukikije, selile ni ibikoresho byonyine.
Muri putty idashobora kwihanganira amazi, igabanijwemo ubwoko bubiri: ifu yumye yumye na paste. Muri ubu bwoko bubiri bwa putty, methyl selulose na hydroxypropyl methyl bigomba guhitamo. Ibisobanuro bya viscosity muri rusange biri hagati ya 40000-75000cps. Ibikorwa nyamukuru bya selile ni ukubika amazi, guhuza no gusiga.
Kubera ko formulaire ya putty yinganda zitandukanye zitandukanye, zimwe ni calcium yumukara, calcium yumucyo, sima yera, nibindi, nibindi, ni ifu ya gypsumu, calcium yumukara, calcium yumucyo, nibindi, bityo rero ibisobanuro, viscosity no kwinjira muri selile muri formula ebyiri nazo ziratandukanye. Amafaranga yongeweho ni 2 ‰ -3 ‰.
