Cellulose ether ni ubwoko bwa polymeric non-ionic semi-synthique polymer, hamwe no gukemura amazi no gukemurwa kwubwoko bubiri, mu nganda zitandukanye zatewe ninshingano ziratandukanye, nko mubikoresho byubaka imiti, bifite ingaruka zikurikira: retain kubika amazi umukozi ② umubyimba ③ kuringaniza formation gushiraho firime ⑤ binder;Mu nganda za polyvinyl chloride, ni emulisiferi, ikwirakwiza;Mu nganda zimiti, ni ubwoko bwa binder kandi buhoro kandi bugenzurwa kurekura skeleton, kubera ko selile ifite ingaruka zitandukanye, bityo rero niwo murima ukoreshwa cyane.Hano ndibanda ku mikoreshereze ya selile ya selile mubikoresho byubaka ibidukikije no kubigiramo uruhare.
1, irangi
Mumurongo wamabara ya LATEX, ushaka GUHITAMO hydroxyethyl selulose, ibisobanuro rusange byijimye ni RT30000- 50000CPS, umubare wibisobanuro ni 1.5 ‰ -2 ‰ ibumoso niburyo.Uruhare runini rwa hydroxyethyl mu irangi rya latex ni ukubyimbye, gukumira ihindagurika ry’ibara, kugira uruhare mu gukwirakwiza pigment, latex, gutuza, kandi birashobora kunoza ubwiza bwibigize, bigira uruhare mu mikorere iringaniza yubwubatsi: Hydroxyethyl selulose iroroshye gukoresha, ubukonje n'amazi ashyushye arashobora gushonga, kandi ntibiterwa nagaciro ka PH, hagati ya PH 2 na 12 arashobora gukoreshwa, gukoresha uburyo butatu bukurikira:
I. Ongeraho mu buryo butaziguye:
Ubu buryo bugomba guhitamo hydroxyethyl selulose yatinze ubwoko - igihe cyasheshwe cyiminota irenga 30 ya hydroxyethyl selulose, intambwe yo gukoresha niyi ikurikira: , icyarimwe, kongeramo buhoro buhoro hydroxyethyl kuringaniza igisubizo cya (3) komeza kubyutsa kugeza ibikoresho byose bitose (4) kugirango uhuze nibindi byongewe hamwe ninyongeramusaruro ya alkaline (5) bikurura kugeza bishonge burundu hydroxyethyl, ongeramo ibindi bigize formulaire , gusya ku bicuruzwa byarangiye.
, Bifite ibikoresho byababyeyi bategereje:
Ubu buryo burashobora guhitamo ubwoko bwihuse, kandi bufite mildew - ingaruka zerekana selile.Ubu buryo bufite inyungu zo guhinduka cyane, burashobora kongerwaho muburyo butaziguye irangi rya latex, uburyo bwo gutegura ni kimwe na ①- ④ intambwe.
Ⅲ.Gukora hamwe na poroji:
Kuberako ibishishwa kama bitifuzwa (bitavogerwa) kuri hydroxyethyl, birashobora gukoreshwa mugukora poroje.BIKORESHEJWE CYANE ORGANIC SOLVENT NI LIQUID YO MURI ORGANIQUE MURI LATEX PAINT FORMULA, KUBA NKA GLYCOL, PROPYLENE GLYCOL NA FILM (LIKE DIETHYLENE glycol butyl acetic acide GREASE) MUBIKORWA BIKURIKIRA, NYUMA YO GUHUZA BIRACYAKOMEZA GUKORA GUKEMURA CYANE CYANE.
2, gusiba urukuta
Kugeza ubu, ubwoko bw’ibidukikije bwo kurengera ibidukikije, butarwanya amazi kandi bwangiza amazi mu mijyi myinshi, bwitabiriwe n’abantu muri rusange.Mu myaka mike ishize, kubera ko putty yakozwe mubwubatsi bwa kole irasa gaze ya formaldehyde kugirango yangize ubuzima bwabantu, kole yinyubako ikozwe muri alcool ya polyvinyl na formaldehyde kugirango acetal reaction.Kubwibyo, ibi bikoresho bigenda bikurwaho buhoro buhoro nabantu, kandi gusimbuza ibi bikoresho nibicuruzwa bya selulose ether, bivuze ko guteza imbere ibikoresho byubaka ibidukikije, selile ni ubwoko bwonyine bwibikoresho.
Mu mazi adashobora kwihanganira amazi agabanijwemo ubwoko bubiri bwifu yumye na putty paste, ubu bwoko bubiri bwa putty mubusanzwe bifuza guhitamo methyl selulose yahinduwe na hydroxypropyl methyl ubwoko bubiri, ibisobanuro bya viscosity biri hagati ya 3000-60000CPS bikenewe cyane, nyamukuru Uruhare 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, bityo rero ibisobanuro byijimye hamwe no kwinjira muri selile ya formula zombi ntabwo ari kimwe , umubare rusange wongeyeho ni 2 ‰ -3 ‰.
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 bwuzuza, cyane cyane ivu rya calcium, nabyo ni ngombwa cyane.Kubera ubukonje bwinshi bwa selile, binongera imbaraga zireremba za putty, kandi birinda ibintu byimigezi 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, ongeraho hafi 2 ‰ –3 ‰, igipimo cyo gufata amazi gishobora kwiyongera kugera kuri 85%, gukoresha beto ya minisiteri yifu yumye ivanze neza nyuma yo kongeramo amazi birashobora.
4, irangi rya gypsumu, gypsum yifata, gypsum ya caulking
Iterambere ryihuse ry’inganda z’ubwubatsi, abantu bakeneye ibikoresho bishya by’ubwubatsi na bo bagenda biyongera umunsi ku munsi, kubera ko abantu barushijeho gukangurira abantu kurengera ibidukikije ndetse no kurushaho kunoza imikorere y’ubwubatsi, ibikoresho bya sima ya gypsumu byatejwe imbere byihuse.Kugeza ubu ibicuruzwa bisanzwe bya gypsumu bifite gypsumu ya stucco, gypsumu ihujwe, gypsumu yashyizwemo, tile binder.
Stucco plaster ni ubwoko bwiza bwurukuta rwimbere hamwe nibikoresho byo guhomeka hejuru yinzu, hamwe no guhanagura urukuta biroroshye kandi byoroshye, ntabwo ari ifu, umurunga ukomeye hamwe nifatizo, nta gucamo ibintu, kandi bifite umurimo wo kurinda umuriro;Gypsum ya Adhesive ni ubwoko bushya bwo kubaka plaque yamashanyarazi, ni gypsumu nkibikoresho fatizo, ukongeramo inyongeramusaruro zitandukanye kandi bikozwe mubikoresho bifata neza, birakwiriye kubwoko bwose bwibikoresho byubaka byubatswe hagati yububiko, hamwe nuburozi, uburyohe, imbaraga zambere gushiraho byihuse, guhuza nibindi biranga, ni ikibaho cyubaka, guhagarika ibikoresho bifasha kubaka;Gypsum kashe niyuzuza icyuho kiri hagati yamasahani ya gypsumu no gusana urukuta nibice.
Ibicuruzwa bya gypsumu bifite urutonde rwimirimo itandukanye, usibye gypsumu hamwe nuwuzuza bifitanye isano bigira uruhare, ikibazo cyingenzi nuko inyongeramusaruro ya selile yongeyeho uruhare runini.Kuberako GESSO YATANDUKANYE MU GIHUGU CYA GESSO NA HEMIHYDRATE GESSO, INGARUKA ZITANDUKANYE ZA GESSO ZITANDUKANYE N'IMIKORESHEREZE Y'IBICURUZWA, BIKORESHEJE AMAZI, BIKORESHEJWE BIKURIKIRA.Ikibazo rusange cyibi bikoresho ni ingoma yubusa, imbaraga zambere ntabwo zireba iki kibazo, kugirango iki kibazo gikemuke, ni uguhitamo ubwoko bwa selile na retarder compound ikoreshwa ryuburyo, muriki gice, guhitamo rusange kwa methyl cyangwa hydroxypropyl methyl selulose HPMC 30000– 60000CPS, ongeramo hagati ya 1.5 ‰ –2 ‰, selile kuva yibanze ni kubika amazi bidindiza amavuta.
Nyamara, muriki gikorwa, ntibishoboka kwishingikiriza kuri selile ya selile nka retarder, kandi aside citric retarder igomba kongerwaho kuvangwa kugirango imbaraga zambere zitazagira ingaruka.
Igipimo cyo gufata amazi muri rusange bivuga ubwinshi bwamazi yatakaye atiriwe yinjira hanze.Niba urukuta rwumye, amazi yibanze yo kwinjiza hamwe no guhumeka bisanzwe bituma ibintu bitakaza amazi byihuse, kandi hazabaho n'ingoma yubusa hamwe no guturika.
Ubu buryo bwo gukoresha ifu yumye ivanze ikoreshwa, niba igisubizo gishobora kwerekeza kuburyo bwo gutegura igisubizo.
5. Amashanyarazi yubushyuhe
Ubushyuhe bwa termal ni ibikoresho bishya byo kubika urukuta 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 10000cps) iratoranijwe, kandi dosiye iri hagati ya 2 ‰ na 3 ‰.Uburyo ni uburyo bwo kuvanga ifu yumye.
6, umukozi wa interineti
Guhitamo intumwa ya interineti HPMC20000cps, guhitamo tile guhuza ibirenga 60000CPS, mubakozi ba interineti byibanda kumubyimba, birashobora kunoza imbaraga zingutu nimbaraga zimyambi nizindi ngaruka.
