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 zo gusiga amarangi ya latex, kugirango uhitemo hydroxyethyl selulose, ibisobanuro rusange byubwiza bungana ni RT30000-50000cps, 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 ubwubatsi: 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:
(1) 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 ④ Ongeraho izindi nyongeramusaruro ninyongera shingiro, nibindi. ibicuruzwa byarangiye.
(2) 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.
(3), yiswe igikoma kugirango ikoreshwe 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.
2. Mu rukuta rwo gusiba
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. Ibikorwa byingenzi bya selile muri putty 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 ‰.
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.
Nibyiza cyane kongeramo selulose ether muri powder putty. Umusaruro wacyo no gukoresha biroroshye. Uzuza hamwe ninyongeramusaruro zirashobora kuvangwa neza muri poro yumye.
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 hydrated y'imbere ikaba ituzuye, bityo igisubizo cyiki kibazo nukwongerera ibikoresho umunani bigumana amazi kuri beto ya minisiteri, muri rusange hitamo hydroxypropyl methyl cyangwa methyl Cellulose, ibisobanuro bya viscosity biri hagati ya 20000-60000cps, naho amafaranga yongeyeho ni 2% -3%. Igipimo cyo gufata amazi kirashobora kwiyongera kugera kuri 85%. Uburyo bwo gukoresha muri beto ya minisiteri ni ukuvanga ifu yumye neza hanyuma ukayisuka mumazi.
4. Mu guhomesha gypsumu, guhuza gypsumu, gypsumu
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. Ibikoresho bishya byubaka amatara yometseho ni ibikoresho bifatanye bikozwe muri gypsumu nkibikoresho fatizo hamwe ninyongera zitandukanye. Birakwiriye guhuza ibikoresho bitandukanye byubaka inyubako. Ntabwo ari uburozi, Impumuro nziza, imbaraga za kare no gushiraho byihuse, guhuza bikomeye nibindi biranga, ni ibikoresho bifasha imbaho zubaka no kubaka kubaka; gypsum caulking agent ni icyuho cyuzuza imbaho za gypsumu nuwuzuza gusana inkuta.
Ibicuruzwa bya gypsumu bifite urukurikirane rwimirimo itandukanye. Usibye uruhare rwa gypsumu hamwe nuwuzuza, ikibazo cyingenzi nuko inyongeramusaruro ya selile yongeyeho uruhare runini. Kubera ko 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 ni 1.5% –2%. Muri byo, selile yibanda ku 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 yumuriro
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
Hitamo HPNC 20000cps kubakozi ba interineti, hitamo 60000cps cyangwa irenga kuri tile yometse kuri tile, hanyuma wibande kubyimbye muri agent ya interineti, bishobora kuzamura imbaraga zingutu nimbaraga zo kurwanya imyambi.
