Imikorere nogukoresha selulose ether mubikoresho byubaka ibidukikije
Cellulose etherni polimeri idafite ionic igice cya sintetike, gushonga amazi no gushonga kabiri, mubikorwa bitandukanye biterwa ninshingano biratandukanye, nko mubikoresho byubaka imiti, bifite ingaruka:
Agent igumana amazi
Agent umubyimba
Kuringaniza
Forming Gukora firime
Inder binder;
Mu nganda za PVC, ni emulifier, ikwirakwiza; Mu nganda zimiti, ni ubwoko bwo guhuza no gusohora buhoro buhoro ibikoresho bya skeleton, kubera ko selile ifite ingaruka zitandukanye, bityo rero niwo murima ukoreshwa cyane. Hasi ndibanda kumikoreshereze ya selulose ether mubikoresho byubaka ibidukikije no kubigiramo uruhare.
1. irangi
Mumurongo wamabara ya latex, kugirango uhitemo hydroxyethyl selulose, ibisobanuro rusange byijimye ni RT3000-50000cps, dosiye ikoreshwa ni 1.5 ‰ -2 ‰. Uruhare rwibanze rwa hydroxyethyl mu irangi rya latex ni ukubyimba, gukumira ingirabuzimafatizo, kugira uruhare mu gukwirakwiza pigment, latex, ituze, kandi birashobora kunoza ubwiza bwibigize, bigira uruhare mu mikorere iringaniza yubwubatsi: Hydroxyethyl selulose iroroshye gukoresha, irashobora gushonga mumazi akonje kandi ashyushye, kandi ntabwo ihindurwa nagaciro ka PH, irashobora gukoreshwa hagati ya PH agaciro ka 2 na 12, gukoresha uburyo butatu bukurikira:

I. Ongeraho mu buryo butaziguye:
Kuri ubu buryo, hydroxyethyl selulose yatinze ubwoko - hydroxyethyl selulose hamwe nigihe cyo kumara iminota irenga 30 igomba guhitamo. Uburyo bukurikira: ibikoresho bitose bya granulaire (4) kugirango bifatanye nibindi byongeweho ninyongeramusaruro ya alkaline (5) kubyutsa kugeza hydroxyethyl yose yashonze burundu, ongeramo ibindi bice bigize formula, gusya kubicuruzwa byarangiye.

Ⅱ. Bafite inzoga za nyina:
Ubu buryo burashobora guhitamo byihuse - gushonga selile, kandi bifite mildew - ingaruka zerekana. Ibyiza byubu buryo ni ukugira ihinduka rinini, rishobora guhuza irangi rya emulsioni mu buryo butaziguye, gukora uburyo ni kimwe na ① - ④ intambwe ni imwe.

, Hamwe na poroji yo gukoresha:
Kubera ko ibishishwa kama ari ibishishwa bikennye (bidashobora gushonga) kuri hydroxyethyl, birashobora gukoreshwa mugutegura igikoma. Amashanyarazi akoreshwa cyane ni amavuta kama mumyanda ya latx, nka Ethylene glycol, propylene glycol hamwe na firime ikora (nka diethylene glycol butyl acetate), hydroxyethyl selulose ya porojora irashobora kwongerwaho irangi, nyuma yo kongeramo, komeza kubyutsa kugeza bishonge burundu.
2. Gukuraho urukuta
Kugeza ubu, Ubushinwa buri mu turere twinshi two kurwanya amazi mu mujyi, kurwanya abantu benshi mu rwego rwo kurengera ibidukikije byafatanywe uburemere n’abantu, mu myaka mike ishize, kubera ko ibishishwa bikozwe mu kashe byerekana imyuka yangiza ubuzima bwa muntu, inyubako kole ikozwe muri alcool ya polyvinyl na reaction ya formaldehyde. Ibi bikoresho rero bigenda bikurwaho buhoro buhoro nabantu, kandi gusimbuza ibi bikoresho ni selulose ether yuruhererekane rwibicuruzwa, bivuze ko guteza imbere ibikoresho byubaka ibidukikije, selile ni ubwoko bwonyine bwibikoresho muri iki gihe.
Mu mazi adashobora kwihanganira amazi agabanijwemo ifu yumye na putty paste ubwoko bubiri, ubwoko bubiri bwa putty muri rusange hitamo methyl selulose yahinduwe na hydroxypropyl methyl ubwoko bubiri, ibisobanuro bya viscosity mubisanzwe muri 3000-60000cps hagati yabikwiye, muruhare runini rwa selile muri putty ni ukubika amazi, guhuza, gusiga, nibindi ..
Kuberako amata ya putty ya buriwukora atameze kimwe, amwe ni calcium yumukara, calcium yumucyo, sima yera, bimwe ni ifu ya gypsumu, calcium yumukara, calcium yumucyo, nibindi, bityo rero ibisobanuro byijimye hamwe nubucengezi bwa selile ya formula zombi. ntabwo arimwe, umubare rusange wongeyeho ni 2 ‰ -3 ‰ cyangwa.
Urukuta rwo kurambirwa no kurambirwa no kubaka abana, urukuta rufite urukuta runaka (urukuta rw'amatafari rw'igipimo cya Bibiliya rwari 13%, beto ni 3-5%), hamwe no guhumeka kw'isi, bityo niba urambiwe umwana gutakaza amazi byihuse, byaviramo gucika cyangwa ibintu nkibimera, kugirango imbaraga za putty zigabanuke, kubwibyo, nyuma yo kwinjira muri selile ya ether izakemura iki kibazo. Ariko ubwiza bwo kuzuza ibikoresho, cyane cyane ubwiza bwa calcium yumukara nabwo ni ngombwa cyane. Kubera ubukonje bwinshi bwa selile, binongera imbaraga zo gushira, kandi birinda ibintu bitemba bimanikwa mubwubatsi, kandi biroroshye kandi bizigama imirimo nyuma yo gusiba.
3. amabuye ya beto
Muri minisiteri ya beto, rwose igere ku mbaraga zanyuma, igomba gutuma hydrata hydrata reaction rwose, cyane cyane mugihe cyizuba, mukubaka amazi ya beto yatakaje byihuse, ingamba zuzuye zuzuye mugukiza amazi, ubu buryo ni uguta umutungo wamazi kandi imikorere idahwitse, urufunguzo ruri hejuru yubuso, amazi na hydratiya biracyari byuzuye, kuburyo rero inzira zo gukemura iki kibazo, Muri beto ya minisiteri muri rusange hitamo kongeramo hydroxypropyl methyl selulose cyangwa methyl selulose, ibisobanuro bya viscosity hagati ya 20000–60000cps, wongeyeho amafaranga ya 2 ‰ –3 ‰ cyangwa irenga, igipimo cyo gufata amazi gishobora kwiyongera kugera kuri 85%, muburyo bwo gukoresha beto ya minisiteri yo gukoresha ifu yumye ivanze neza nyuma yo kongeramo amazi.

Iterambere ryihuse ry’inganda z’ubwubatsi, abantu bakeneye ibikoresho bishya by’ubwubatsi na bo bagenda biyongera umunsi ku munsi, kubera ko abantu barushaho gukangurira abantu kurengera ibidukikije ndetse no kurushaho kunoza imikorere y’ubwubatsi, ibicuruzwa bya gypsumu ya simaitima byateye imbere byihuse. Kugeza ubu ibicuruzwa bisanzwe bya gesso bifite stucco gesso, cake gesso, shiraho gesso, umukozi wa tile caking kugirango utegereze.
Plaster ni ubwoko bwiza cyane bwurukuta rwimbere hamwe nibikoresho byo guhomesha ibisenge, hamwe no guhanagura urukuta biroroshye kandi byoroshye, ntugabanye ifu, kandi umurunga fatizo ushikamye, nta guca ibintu, kandi ufite ibikorwa byo gukumira umuriro; Gypsum yometseho ni ubwoko bushya bwo kubaka ikibaho cyumucyo gifata neza, gypsumu nkibikoresho fatizo, hiyongereyeho inyongeramusaruro zitandukanye kandi bikozwe mubikoresho bifatanye, birakwiriye kubwoko bwose bwibikoresho byububiko byububiko budahuza, hamwe nuburozi, butaryoshye, kare imbaraga no gushiraho byihuse, guhuza ni ikibaho cyubaka, guhagarika ibikoresho byubaka; Gypsum seam yuzuza ibikoresho ni isahani ya gypsum hagati yikuzuza ibikoresho nu rukuta, gusana ibyuzuye.
Ibicuruzwa bya gypsumu bifite urutonde rwimirimo itandukanye, usibye gypsumu hamwe nuwuzuza bifitanye isano kugirango bigire uruhare, ikibazo cyingenzi ninyongera selile yongeyeho selile igira uruhare runini. Nkibisubizo bya gesso cent idafite amazi ya gesso hamwe nijanisha rya kimwe cya kabiri cyamazi gesso, gesso itandukanye niyindi mikorere yibicuruzwa, kwiyongera cyane, kurinda amazi, gutinda buhoro buhoro ubuziranenge bugena ibikoresho byubaka gesso. Ikibazo gikunze kugaragara muri ibyo bikoresho ni kuvunika ingoma, imbaraga zambere ntabwo ziri hejuru, kugirango iki kibazo gikemuke, ni uguhitamo ubwoko bwa selile na retarding agent compound use method method, muriki gice, guhitamo rusange methyl cyangwa hydroxypropyl methyl 30000–60000cps, wongeyeho amafaranga ni 1.5 ‰ –2 ‰ hagati, intego ya selile ni ukubika amazi no kudasiga amavuta.
Nyamara, muribi kugirango wishingikirize kuri selile ya selile nkuko retarder itageze, igomba no kongeramo aside citric retarder nyuma yo kuyivanga ntibizahindura imbaraga zambere.
Igipimo cyo gufata amazi muri rusange bivuga ubwinshi bwamazi yatakaye mugihe habuze amazi yo hanze. Niba urukuta rwumye, ubuso bwibanze bukurura amazi no guhumeka bisanzwe bituma ibintu bitakaza amazi byihuse, kandi hazabaho n'ingoma yubusa hamwe no guturika.
Ubu buryo bwo gukoresha ni ukuvanga ifu yumye, niba gutegura igisubizo bishobora kwerekeza kuburyo bwo gutegura igisubizo.

Ubushyuhe bwa termal nubwoko bushya bwurukuta rwimbere ibikoresho byo kubika ubushyuhe mu majyaruguru yUbushinwa. Nibikoresho byurukuta byashizwemo nubushyuhe bwumuriro, minisiteri na binder. Muri ibi bikoresho, selile igira uruhare runini muguhuza no kongera imbaraga. Mubisanzwe, methyl selulose ifite ubukonje bwinshi (hafi 10000eps) iratoranijwe, kandi dosiye iri hagati ya 2 ‰ na 3 ‰. Uburyo bwo gukoresha ni kuvanga ifu yumye.
6. Umukozi wa interineti
Imigaragarire ya interineti ni HPMC20000cps, umurongo wa tile urenga 60000cps, kandi umukozi wa interineti akoreshwa cyane cyane mubyimbye, bishobora kuzamura imbaraga zingutu nimbaraga zumwambi
