Cellulose etherni polimeri idafite ionic igice cya synthique, ikaba ibora amazi kandi igashonga. Ifite ingaruka zitandukanye mubikorwa bitandukanye. Kurugero, mubikoresho byubaka imiti, bifite ingaruka zikurikira:
AgentIbikoresho bigumana amazi hInkoko eKugaragaza umutungo ilFilm ikora umutungo inderBinder
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 byibanze ku mikoreshereze n'imikorere ya selulose ether mubikoresho bitandukanye byubaka.
(1) Mu irangi rya latex:
I. Ongeraho mu buryo butaziguye mu musaruro: ubu buryo bugomba guhitamo hydroxyethyl selulose yatinze, na hydroxyethyl selulose hamwe nigihe cyo kumara iminota irenga 30, intambwe zayo zikoreshwa nizi zikurikira:
① Shyira umubare munini wamazi meza mubikoresho bifite imashini ivanze cyane
Tangira kubyutsa ubudahwema ku muvuduko muke, kandi icyarimwe wongereho buhoro buhoro hydroxyethyl kubisubizo bingana
OntinKomeza kuvanga kugeza granules zose zashizwemo
Ongeraho izindi nyongeramusaruro ninyongera shingiro, nibindi
⑤Komeza kugeza amatsinda yose ya hydroxyethyl yasheshwe burundu, hanyuma ongeramo ibindi bice muri formula, hanyuma usya kugeza ibicuruzwa byarangiye.
Ⅱ. Bifite inzoga za nyina kugirango zikoreshwe nyuma: Ubu buryo burashobora guhitamo selulose ihita, igira ingaruka zo kurwanya indwara. Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kongerwaho muburyo butaziguye. Uburyo bwo gutegura nuburyo bumwe nintambwe ①-④.
Ⅲ. Tegura igikoma kugirango gikoreshwe nyuma: Kubera ko ibishishwa kama ari ibishishwa bibi (bitavogerwa) kuri hydroxyethyl, iyi mashanyarazi irashobora gukoreshwa mugutegura igikoma. 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 gusiba urukuta:
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.
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 hydrata y'imbere iracyuzuye. Kubwibyo, igisubizo cyiki kibazo nukwongeramo ibintu umunani bigumana amazi kuri beto ya minisiteri. Mubisanzwe, hydroxypropyl methyl cyangwa methyl Cellulose, ibisobanuro bya viscosity biri hagati ya 20000-60000cps, kandi 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.

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 ari hagati ya 1.5% na 2%, kandi intandaro ya selile ni ukubika 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
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 hamwe nubwiza bwinshi (hafi 10000eps), dosiye iri hagati ya 2% -3%, kandi uburyo bwo gukoresha ni kuvanga ifu yumye.
(6) Intumwa
HitamoHPMC20000cps kuri agent ya interineti, hitamo 60000cps cyangwa irenga kuri tile yometse kuri tile, hanyuma wibande kumubyimba mwinshi mubikorwa bya interineti, bishobora kuzamura imbaraga zingutu nimbaraga zo kurwanya imyambi. Ikoreshwa nkibikoresho bigumana amazi muguhuza amabati kugirango wirinde amabati kutagira umwuma vuba no kugwa.
