Cellulose ether ni ubwoko bwa ionic semi-synthique polimerike ya polymer. Ifite ubwoko bubiri bwamazi-ashonga kandi ashingiye kumashanyarazi. Ifite ingaruka zitandukanye mubikorwa bitandukanye. Kurugero, mubikoresho byubaka imiti, bifite ingaruka zikurikira: agent Umukozi ugumana amazi hThickener ③Gukunda ④ Gukora firime ⑤Binder; mu nganda za PVC, ni emulisiferi kandi ikwirakwiza; mu nganda zimiti, ni binder kandi Kuberako selile ifite ingaruka zitandukanye zingirakamaro, nayo ikoreshwa cyane. Hasi nzibanda kumikoreshereze n'imikorere ya selile ya selile mubikoresho byubaka 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 nukubyibuha, gukumira ingirabuzimafatizo, gufasha gutatanya pigment, latex, no gutuza, kandi birashobora kunoza ubwiza bwibigize kandi bikagira uruhare mubikorwa byo kubaka: 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 bukurikira:
I. Ongeraho muburyo butaziguye:
Ubu buryo bugomba guhitamo hydroxyethyl selulose yatinze - hydroxyethyl selulose hamwe nigihe cyo kumara iminota irenga 30. Intambwe zo gukoresha nizi zikurikira: ① Ongeramo umubare munini wamazi meza kubintu hamwe na agiteri-yogosha cyane ② Tangira kubyutsa ubudahwema kumuvuduko muke, kandi icyarimwe buhoro buhoro kandi binganya kongeramo hydroxyethyl mumuti ③ Komeza ubyutsa kugeza ibikoresho byose bya granulaire byashizwemo ④ Ongeramo izindi nyongeramusaruro ninyongeramusaruro za alkaline, nibindi. gusya kugeza birangiye.
Ⅱ. Bafite inzoga za nyina:
Ubu buryo burashobora guhitamo ubwoko bwihuse, kandi bufite ingaruka za anti-mildew selile. Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kongerwaho muburyo butaziguye irangi rya latex. Uburyo bwo kwitegura ni kimwe n'intambwe za ① - ④.
Ⅲ. Mugutegura imitungo isa na poroji:
Kubera ko ibishishwa kama ari ibishashara bikennye (bidashobora gukemuka) kumatsinda ya hydroxyethyl, porojeri irashobora gutegurwa hamwe nuyu muti. Amashanyarazi akoreshwa cyane ni amavuta kama mumavuta ya latx, nka Ethylene glycol, propylene glycol hamwe nabakora firime (nka diethylene glycol butyl acetate). Porridge hydroxyethyl selulose irashobora kongerwaho muburyo butaziguye. Komeza kubyutsa kugeza bishonge burundu.
2, gusiba urukuta
Kugeza ubu, ibidukikije byangiza ibidukikije birwanya amazi kandi birwanya scrub mu mijyi myinshi yo mu gihugu cyanjye byahawe agaciro n’abantu. Mu myaka mike ishize, kubera ko putty ikozwe muri kole yubaka isohora gaze ya formaldehyde kandi ikangiza ubuzima bwabantu, kole yubaka ikozwe muri polymer Yateguwe na acetal reaction ya vinyl alcool na formaldehyde. Kubwibyo, ibi bikoresho bigenda bikurwaho buhoro buhoro nabantu, kandi ibicuruzwa bya selile ya ether byasimbuwe nibi bikoresho, ni ukuvuga ko iterambere ryibikoresho byubaka ibidukikije bitangiza ibidukikije, selile nicyo kintu cyonyine muri iki gihe.
Muri putty idashobora kwihanganira amazi, igabanyijemo ifu yumye na paste. Muri ubu bwoko bubiri bwa putty, yahinduwe methyl selulose na hydroxypropyl methyl muri rusange byatoranijwe. 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 zinyuranye zitandukanye, zimwe ni calcium yumukara, calcium yumucyo, sima yera, nibindi, nibindi, ni ifu ya gypsumu, calcium yumukara, calcium yumucyo, nibindi, bityo rero formula zombi zihitamo selile ya selile, viscosity no kwinjira. . Amafaranga yiyongereyeho agera kuri 2 ‰ -3 ‰.
Mu iyubakwa ry'urukuta rusakaye, kubera ko hejuru y'urukuta rufite amazi runaka (igipimo cyo gufata amazi y'urukuta rw'amatafari ni 13%, naho igipimo cyo gufata amazi ya beto ni 3-5%), hamwe na guhumeka kwisi, niba putty yatakaje amazi byihuse, bizatera kuvunika cyangwa kuvanaho ifu nibindi bintu, bityo bigabanye imbaraga za putty. Kubera iyo mpamvu, kongeramo selile ether bizakemura iki kibazo. Ariko ubwiza bwuzuza, cyane cyane ubwiza bwa calcium ya lime, nabwo ni ngombwa cyane. Kuberako selile ifite ubukonje bwinshi, nayo yongerera imbaraga za putty, ikirinda kugabanuka mugihe cyubwubatsi, kandi ikoroha kandi igakoresha imirimo nyuma yo gusiba.
3. Amabuye ya beto
Muri minisiteri ya beto, kugirango rwose igere ku mbaraga zanyuma, sima igomba kuba yuzuye neza cyane cyane mubwubatsi bwimpeshyi, minisiteri ya beto itakaza amazi byihuse, kandi hafatwa ingamba zo gufata amazi yuzuye kugirango babungabunge kandi baminjagire amazi. Gupfusha ubusa umutungo no gukora nabi, urufunguzo ni uko amazi ari hejuru gusa, kandi hydrata y'imbere ikaba ituzuye, igisubizo cyiki kibazo rero ni ukongera hydroxypropyl methyl selulose cyangwa methyl selulose kuri beto ya minisiteri. Ibisobanuro bya viscosity biri hagati ya 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 ukuvanga ifu yumye neza hanyuma ukongeramo amazi.
4. Mu guhomesha plaster, guhuza plaster na plaque
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 gypsum bikunze kugaragara ni uguhomesha gypsumu, guhuza gypsumu, gushiramo gypsumu, gufatira tile n'ibindi.
Stucco plaster ni ubwoko bwibikoresho byo mu rwego rwo hejuru byo guhomesha inkuta zimbere no hejuru. Inkuta zometseho ni nziza kandi yoroshye, ntugabanye ifu, uhambire neza kuri substrate, ntugacika kandi ugwa, kandi ufite kurwanya umuriro; guhuza plaster ni ubwoko bwa plaster. Ubwoko bushya bwo kubaka urumuri rufata neza ni ibikoresho bifatanye bikozwe muri gypsumu nkibikoresho fatizo no kongeramo inyongeramusaruro zitandukanye. Birakwiriye guhuza ibikoresho bitandukanye byubaka inyubako. Ntabwo ari uburozi, butaryoshye, Ifite ibiranga imbaraga hakiri kare, gushiraho byihuse no guhuza bikomeye, kandi nibikoresho bifasha kubaka imbaho zubatswe;
Ibicuruzwa bya gypsumu bifite urukurikirane rwibikorwa bitandukanye, usibye uruhare rwa gypsumu hamwe nuwuzuza bifitanye isano, ikibazo cyingenzi nuko infashanyo ya selile yongeyeho uruhare runini. Kubera ko gypsumu igabanyijemo gypsumu ya anhydrite na hemihydrate, gypsumu itandukanye igira ingaruka zitandukanye kumikorere yibicuruzwa, bityo kubyimba, kubika amazi no kudindiza bigena ubwiza bwibikoresho byubaka gypsumu. Ikibazo rusange cyibi bikoresho ni ugusenyuka, kandi imbaraga zambere ntizishobora kugerwaho. Kugira ngo iki kibazo gikemuke, nikibazo cyo guhitamo ubwoko bwa selile hamwe nuburyo bwo gukoresha uburyo bwa retarder. Ni muri urwo rwego, methyl cyangwa hydroxypropyl methyl 30000 muri rusange byatoranijwe. –60000cps, amafaranga yiyongereye ari hagati ya 1.5 ‰ –2 ‰, intumbero ya selile ni ukubika amazi, kudindiza no gusiga.
Ariko rero, ntibishoboka kwishingikiriza kuri selile ya selile nka retarder, kandi birakenewe ko wongera aside citric retarder kugirango uyivange kandi uyikoreshe kugirango imbaraga zambere zitazagira ingaruka.
Igipimo cyo gufata amazi muri rusange bivuga gutakaza bisanzwe kwamazi mugihe habuze amazi yo hanze. Niba urukuta rwumye cyane, kwinjiza amazi no guhumeka bisanzwe hejuru yubutaka bizatera ibikoresho gutakaza amazi vuba, kandi gutobora no guturika nabyo bizabaho.
Ubu buryo bwo gukoresha buvanze nifu yumye. Niba igisubizo cyateguwe, nyamuneka reba uburyo bwo gutegura igisubizo.
5
Amashanyarazi yubushyuhe nubwoko bushya bwurukuta rwimbere ibikoresho byo kubika ubushyuhe mu karere ka majyaruguru. Nibikoresho byurukuta rugizwe nubushyuhe bwumuriro, 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 nuburyo bwo kuvanga ifu yumye.
6. Umukozi wa interineti
Imigaragarire ya interineti ni HPNC20000cps, kandi ifata ya tile irenga 60000cps. Mubikorwa byimbere, bikoreshwa cyane nkibyimbye, bishobora kuzamura imbaraga zingutu no kurwanya imyambi.
