Cellulose ether ni polimeri idafite ionic igice cya sintetike, ikabura amazi kandi igashonga.Ifite ingaruka zitandukanye mubikorwa bitandukanye.Kurugero, mubikoresho byubaka imiti, bifite ingaruka zikurikira: agent umukozi wo kubika amazi ② umubyimba ③ kuringaniza umutungo property umutungo ukora firime ⑤ binder;mu nganda za polyvinyl chloride, ni emulisiferi kandi ikwirakwiza;mu nganda zimiti, ni binder na buffering agent Kurekura ibikoresho bya skeleton, nibindi, kuko selile ifite ingaruka zitandukanye zingirakamaro, bityo imirima yabyo nayo ni nini cyane.Ibikurikira, nzibanda ku mikoreshereze n'imikorere ya selulose ether mubikoresho byo kubaka ibidukikije.
1. Mu irangi rya latex
Mu nganda za latex, hydroxyethyl selulose igomba guhitamo.Ibisobanuro rusange byijimye ni RT30000-50000cps, naho dosiye ikoreshwa ni 1.5 ‰ -2 ‰.Igikorwa nyamukuru cya hydroxyethyl mumarangi ya latex nukubyimbye, gukumira gelation ya pigment, gufasha gutatanya, latex, hamwe no gutuza kwa pigment, no kongera ububobere bwibigize, bifasha mumikorere iringaniza yubwubatsi: hydroxyethyl Ethyl selulose iroroshye gukoresha.Irashobora gushonga mumazi akonje namazi ashyushye, kandi ntabwo ihindurwa nagaciro ka pH.Irashobora gukoreshwa hagati ya pH agaciro ka 2 na 12. Hariho uburyo butatu bwo gukoresha:
I. Ongeraho muburyo butaziguye:
Ubu buryo bugomba guhitamo hydroxyethyl selulose yatinze - hydroxyethyl selulose hamwe nigihe cyo kumara iminota irenga 30.Intambwe nizi zikurikira: ① Ongeramo umubare munini wamazi meza mubikoresho bifite 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 granulaire byashizwemo dd Ongeraho izindi mfashanyo 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 gutegura nuburyo bumwe nintambwe ①-④.
Ⅲ.Witegure muri poroji 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.
2. Mu rukuta rusiba
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, yahinduwe methyl selulose na hydroxypropyl methyl igomba guhitamo.Ibisobanuro bya viscosity mubisanzwe biri hagati ya 30000-60000cps.Igikorwa nyamukuru cya selile muri putty ni ukubika amazi, guhuza, gusiga amavuta nibindi.
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 ‰.
Mu iyubakwa ry'urukuta rusakaye, kubera ko hejuru y'urukuta rufite urugero runaka rwo kwinjiza amazi (igipimo cyo gufata amazi y'urukuta rw'amatafari ni 13%, naho igipimo cyo gufata amazi ya beto ni 3-5%), ufatanije no guhumeka kwisi, niba putty itakaza amazi vuba, Bizagushikana kumeneka cyangwa kuvanaho ifu, bizagabanya imbaraga za putty.Kubwibyo, kongeramo selile ether bizakemura iki kibazo.Ariko ubwiza bwuzuza, cyane cyane ubwiza bwa calcium yivu nayo ni ngombwa cyane.Bitewe n'ubukonje bwinshi bwa selile, ubwinshi bwa putty nabwo bwiyongera, kandi ibintu byo kugabanuka mugihe cyubwubatsi nabyo biririndwa, kandi biroroshye kandi bizigama imirimo nyuma yo kubisiba.
3. Amabuye ya beto
Muri beto ya beto, kugirango igere ku mbaraga zanyuma, sima igomba kuba yuzuye neza.Cyane cyane mubwubatsi, icyuma cya beto gitakaza amazi vuba, kandi ingamba zo gufata neza zikoreshwa mukubungabunga no kuminjagira amazi.Gupfusha ubusa umutungo no gukora nabi, urufunguzo ni uko amazi ari hejuru gusa, kandi hydrata y'imbere ikaba ituzuye, bityo igisubizo cyiki kibazo nukwongeramo hydroxypropyl methylcellulose cyangwa methylcellulose kuri beto ya minisiteri, Ibisobanuro bya viscosity biri hagati 20000–60000cps, amafaranga yiyongereyeho agera kuri 2 ‰ –3 and, kandi igipimo cyo gufata amazi gishobora kwiyongera kugera kuri 85%.Uburyo bwo gukoresha muri beto ya minisiteri ni ukongeramo amazi nyuma yifu yumye ivanze neza.
4. Mu guhomesha gypsumu, guhuza gypsumu, gypsum ya caulking
Hamwe niterambere ryihuse ryinganda zubaka, abantu bakeneye ibikoresho byubaka nabyo biriyongera umunsi kumunsi.Bitewe no kongera ubumenyi bw’abantu ku bijyanye no kurengera ibidukikije no gukomeza kunoza imikorere y’ubwubatsi, ibicuruzwa bya gypsumu ya sima byateye imbere byihuse.Kugeza ubu, ibicuruzwa bya gypsumu bikunze kugaragara ni ugupompa gypsumu, gypsumu ihujwe, gypsumu yometseho, hamwe na tile yometse.
Gutera gypsumu ni ibikoresho byo mu rwego rwo hejuru byo guhomesha inkuta zimbere no hejuru.Ubuso bwurukuta rwometseho ni byiza kandi byoroshye, ntibuterera ifu, ihambiriye ku musingi, nta gucika no kugwa, kandi ifite imikorere idacana umuriro;gypsum ihujwe nubwoko bushya bwo kubaka urumuri rwumucyo ni ibikoresho bifatanye bikozwe muri gypsumu nkibikoresho fatizo no kongeramo inyongeramusaruro zitandukanye.Birakwiriye guhuza ibikoresho bitandukanye byubaka inyubako.Ntabwo ari uburozi, butaryoshye, Ibiranga nkimbaraga hakiri kare, gushiraho byihuse, no guhuza gukomeye, ni ibikoresho bifasha kubaka panne no kubaka kubaka;gypsum caulking agent ni icyuho cyuzuza hagati ya panne ya gypsum nuwuzuza gusana inkuta n'ibisate.
Ibicuruzwa bya gypsumu bifite urukurikirane rwimirimo itandukanye.Usibye uruhare rwa gypsumu hamwe nuwuzuza, ikibazo cyingenzi nuko inyongeramusaruro ya selile yongeyeho uruhare runini.Kuberako gypsumu igabanyijemo gypsumu ya anhydrous na gypsum ya hemihydrate, gypsumu itandukanye igira ingaruka zitandukanye kumikorere yibicuruzwa, bityo kubyimba, kubika amazi no kudindiza bigena ubwiza bwibikoresho byubaka gypsumu.Ikibazo gisanzwe cyibi bikoresho ni ugutobora no guturika, kandi imbaraga zambere ntizishobora kugerwaho.Kugira ngo iki kibazo gikemuke, ni uguhitamo ubwoko bwa selile hamwe nuburyo bwo gukoresha imikoreshereze ya retarder.Ni muri urwo rwego, methyl cyangwa hydroxypropyl methyl 30000 muri rusange byatoranijwe.–60000cps, amafaranga yiyongereye ari hagati ya 1.5 ‰ –2 ‰, selile ikoreshwa cyane cyane mu gufata amazi no kudasiga amavuta.
Ariko rero, ntibishoboka kwishingikiriza kuri selile ya selile nka retarder, kandi birakenewe kongeramo aside citric retarder kugirango ivange kandi ikoreshe bitagize ingaruka kumbaraga zambere.
Kugumana amazi muri rusange bivuga umubare w'amazi azabura bisanzwe bitarimo amazi yo hanze.Niba urukuta rwumye cyane, kwinjiza amazi no guhumeka bisanzwe hejuru yubutaka bizatuma ibikoresho bitakaza amazi vuba, kandi gutobora no guturika nabyo bizabaho.
Ubu buryo bwo gukoresha buvanze nifu yumye.Niba utegura igisubizo, nyamuneka reba uburyo bwo gutegura igisubizo.
5. Amashanyarazi yubushyuhe
Imisemburo ya insulire ni ubwoko bushya bwibikoresho byo gukingira imbere mu majyaruguru.Nibikoresho byurukuta byashizwemo nibikoresho byo kubika, minisiteri na binder.Muri ibi bikoresho, selile igira uruhare runini muguhuza no kongera imbaraga.Mubisanzwe hitamo methyl selulose ifite ubukonje bwinshi (hafi 10000eps), dosiye iri hagati ya 2 ‰ -3 ‰), kandi uburyo bwo gukoresha ni kuvanga ifu yumye.
6. Umukozi wa interineti
Amatafari ya tile agomba kuba hejuru ya 60.000cps, kandi agomba gukoreshwa nkibyimbye mumikorere ya interineti, bishobora kuzamura imbaraga zingutu nimbaraga zo kurwanya imyambi.
