Imikorere nogukoresha selulose ether

Imikorere nogukoresha selulose ether

Cellulose etherni polimeri idafite ionic igice cya sintetike, gushonga amazi no gushonga kabiri, munganda zitandukanye zatewe ninshingano ziratandukanye, nko mubikoresho byubaka imiti, bifite ingaruka zifatika: agent ibikoresho bigumana amazi agent umubyimba ③ kuringaniza ④ firime ikora ⑤ 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 bitandukanye byubaka ninshingano.

1, irangi rya latex:

Mumurongo wamabara ya latex, guhitamohydroxyethyl selile, ibisobanuro rusange byubwiza ni RT3000-50000cps, bihuye nibisobanuro bya HBR250, 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, amazi akonje kandi ashyushye arashobora gushonga, kandi ntabwo ahindurwa nagaciro ka PH. Irashobora gukoreshwa neza hagati ya PI agaciro 2 na 12. Uburyo bwo gukoresha nuburyo bukurikira:

I. Ongeraho mu buryo butaziguye:

Kuri ubu buryo, hydroxyethyl selulose yatinze hamwe nigihe cyo gusesa iminota irenga 30 igomba guhitamo. Uburyo bukurikira: komeza kubyutsa kugeza ibikoresho byose bitose (4) kugirango wifatanye nibindi byongeweho ninyongeramusaruro ya alkaline (5) kubyutsa kugeza hydroxyethyl yose yashonze burundu, ongeramo ibindi bigize formulaire, usya kubicuruzwa byarangiye.

Ⅱ. Bafite inzoga za nyina:

Ubu buryo burashobora guhitamo byihuse - gushonga selile, kandi bifite mildew - ingaruka zerekana. Ibyiza byubu buryo nuko bifite ihinduka ryinshi kandi birashobora kwongerwaho muburyo butagaragara mu irangi rya latex, uburyo bwo gutegura ni bumwe na ① - ④ intambwe.

, 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, gusiba urukuta muri putty:

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 hamwe nizindi ngaruka.

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.

Mu ifu ya poro, selile ya selile igomba kongerwaho muburyo bwuruganda, umusaruro wabyo, gukoresha biroroshye, kuzuza ibikoresho hamwe nifu yumye ifasha irashobora kuvangwa neza, kubaka biroroshye, gukwirakwiza amazi yikibanza, uko bingana nangahe. 

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 gusa, amazi na hydrasiya ntabwo biracyari byuzuye, kuburyo rero inzira zo gukemura iki kibazo, Ongeramo umunani selile igumana amazi selile muri beto ya minisiteri kugirango uhitemo hydroxypropyl methyl cyangwa methyl selulose, ibisobanuro bya viscosity muri 20000– 60000cps hagati, ongeramo 2% –3%. Hafi, igipimo cyo gufata amazi kirashobora kwiyongera kugera kuri 85%, muburyo bwa beto ya minisiteri yo gukoresha ifu yumye iringaniye ivanze nyuma yiminwa mumazi.

4, irangi rya gypsumu, guhuza gypsumu, gypsumu ya caulking:

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.

Guhomesha plaster ni ubwoko bwiza bwurukuta rwimbere hamwe nibikoresho byo guhomeka hejuru yinzu, hamwe no guhanagura urukuta rworoshye kandi rworoshye, ntugabanye ifu nububiko bwibanze, nta guca ibintu, kandi bifite ibikorwa byo gukumira umuriro; Gypsum yometseho ni ubwoko bushya bwo kubaka urumuri ruto rwometseho, gypsumu nkibikoresho fatizo, hiyongereyeho uburyo butandukanye bwo kongeramo imbaraga umunwa wakozwe mubikoresho bifata neza, birakwiriye kubwoko bwose bwibikoresho byubaka byubatswe hagati yububiko, hamwe nuburozi. , uburyohe, imbaraga zambere 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. Kuberako gesso igabanijwe ifite nta gesso yamazi hamwe na cent ya kimwe cya kabiri cyamazi ya gesso, gesso itandukanye niyindi mikorere yibicuruzwa, kwiyongera cyane, kurinda amazi, gutinda 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 retarder compound ikoreshwa ryuburyo bukoreshwa, muriki gice, guhitamo rusange methyl cyangwa hydroxypropyl methyl 30000–60000cps, wongeyeho amafaranga ni 1.5% - 2%. Hagati aho, intumbero ya selile ni ukubika amazi no gusiga buhoro buhoro.

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 10,000 CPS) iratoranijwe, kandi dosiye iri hagati ya 2 ‰ na 3 ‰. Uburyo bwo kuvanga ifu yumye irakoreshwa.

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.
