Ingaruka ya selile ya ether kuri tile yometse

Isima ishingiye kuri ceramic tile yometse kuri ubu ni yo nini ikoreshwa cyane mu kuvanga amavuta yihariye yumye, akaba ari ubwoko bwa sima nkibikoresho nyamukuru bya sima kandi byuzuzwa no gutondekanya igiteranyo rusange, kubika amazi, imbaraga za kare, ifu ya latex nibindi binyabuzima cyangwa bidafite ingufu imvange.Mubisanzwe bikoreshwa gusa kuvanga amazi, ugereranije na minisiteri isanzwe ya sima, birashobora kunoza cyane imbaraga zihuza hagati yibikoresho birangira nibikoresho fatizo, bifite anti-kunyerera kandi bifite amazi meza cyane, birwanya ubushyuhe hamwe nibyiza byo gukonjesha, cyane cyane bikoreshwa mugushiraho inyubako yimbere ninyuma yinyuma, amabati hasi nibindi bikoresho byo gushushanya, Irakoreshwa cyane mugushushanya inkuta, amagorofa, ubwiherero, igikoni nizindi nyubako.Nibikoresho bikoreshwa cyane muri ceramic tile ihuza ibikoresho.

Mubisanzwe iyo dusuzumye imikorere ya ceramic tile yometseho, usibye kwitondera imikorere yayo, ubushobozi bwo kurwanya kunyerera, ariko tunitondera imbaraga zumukanishi nigihe cyo gufungura.Cellulose ether kuri ceramic tile yometseho usibye kugira ingaruka kumiterere ya rheologiya ya kole ya farashi, nko gukora neza, imikorere yicyuma, ariko no kumiterere yubukorikori bwa ceramic tile yifata ifite imbaraga zikomeye

1. Funguraigihe

Iyo ifu ya reberi na selulose ether bibana hamwe na minisiteri itose, moderi zimwe zerekana ko ifu ya reberi ifite imbaraga za kinetic kugirango zubahirize ibicuruzwa bivamo sima, kandi ether ya selile ibaho cyane mumazi yo mu cyuho, bigira ingaruka kumyuka no kugena igihe cya minisiteri. byinshi.Ubusumbane bwubuso bwa selile ya selile nini kuruta iy'ifu ya reberi, kandi gutunganyiriza ether nyinshi ya selile kuri interineti ya minisiteri ni ingirakamaro mu gushiraho imigozi ya hydrogène hagati yindege shingiro na selile.

Guhumeka neza biva mu butaka butose, minisiteri, selile ya ether mu gutunganya ubutaka, iminota 5 irashobora gukora ururenda hejuru ya minisiteri, bizagabanya umuvuduko wo guhumeka kubikurikirana, hamwe n’amazi menshi ava mu gice cyinshi cya kwimukira kumurongo wa minisiteri yoroheje, ingingo zifunguye igice zishonga mugihe habayeho gutangira kwambere, kwimuka kwamazi birashobora kuzana ubutunzi bwinshi bwa selile ya ether muri minisiteri hejuru.

Imiterere ya firime ya selile ether hejuru ya minisiteri igira uruhare runini kumiterere ya minisiteri:

Ubwa mbere, firime yakozwe ni ntoya cyane, izashonga kabiri, idashobora kugabanya ihinduka ryamazi, kugabanya imbaraga.

Icya kabiri, ishingwa rya firime irabyimbye cyane, selile ya ether mumyanya ya minisiteri ya minisiteri yibintu byinshi, viscosity, mugihe ceramic tile paste ntabwo byoroshye kumena hejuru ya firime.

Birashobora kugaragara ko firime ikora imikorere ya selile ether igira uruhare runini mugihe cyo gufungura.Ubwoko bwa selulose ether (HPMC, HEMC, MC, nibindi) hamwe nurwego rwa etherification (urwego rwo gusimbuza) bigira ingaruka kuburyo butaziguye muri firime ikora imikorere ya selile, kugeza gukomera no gukomera kwa firime.

2, gushushanya imbaraga

Cellulose ether ntabwo itanga minisiteri gusa nibintu byose byavuzwe haruguru bifite akamaro, ahubwo binadindiza hydrated kinetics ya sima.Izi ngaruka zidindiza ahanini ziterwa na adsorption ya molekile ya selile ya selile ku byiciro bitandukanye byamabuye y'agaciro muri sisitemu ya sima ihindurwamo amazi, ariko muri rusange hemejwe ko molekile ya selulose yanduzwa cyane cyane ku bicuruzwa bitanga amazi nka CSH na hydroxide ya calcium, kandi ntibikunze kwandikwa kuri icyiciro cyambere cyamabuye ya clinker.Byongeye kandi, selile ether igabanya ion (Ca2 +, SO42-,…) kubera kwiyongera kwinshi kwumuti wa pore.Igikorwa mubisubizo bya pore, bikomeza kudindiza inzira ya hydration.

Viscosity ni ikindi kintu cyingenzi, kigaragaza imiterere yimiti ya selile.Nkuko byavuzwe haruguru, ubukonje bugira ingaruka cyane cyane kubushobozi bwo gufata amazi, kandi bukagira n'ingaruka zikomeye kumikorere ya minisiteri nshya.Nyamara, ubushakashatsi bwakozwe bwerekanye ko ubwiza bwa selile ya selile nta ngaruka byagize kuri hydrata kinetics ya sima.Uburemere bwa molekuline ntabwo bugira uruhare runini kuri hydration, kandi itandukaniro rinini hagati yuburemere butandukanye bwa molekile ni 10min gusa.Kubwibyo, uburemere bwa molekile ntabwo aribintu byingenzi bigenzura kugenzura sima.

“Cellulose ether muri sima ishingiye ku byumye bivanze na minisiteri ikoreshwa” yerekanye neza ko gutinda kwa selile biterwa na chimique.Icyerekezo rusange nuko kuri MHEC, urwego rwo hejuru rwa methylation, niko ingaruka mbi zo kudindiza selile.Byongeye kandi, gusimbuza hydrophilique (nko gusimbuza HEC) bigira ingaruka zikomeye zo gusimbuza hydrophobique (nko gusimbuza MH, MHEC na MHPC).Ingaruka zo kudindiza selireose ether yibasiwe cyane nibintu bibiri byubwoko numubare witsinda ryasimbuwe.

Ubushakashatsi bwacu butunganijwe kandi bwagaragaje ko ibikubiye mu nsimburangingo bigira uruhare runini mu mbaraga za mashini za ceramic tile adhesive.Twasuzumye imikorere ya HPMC hamwe ninzego zitandukanye zo gusimburana muri ceramic tile yometseho, kandi twagerageje ingaruka za ether ya selile irimo amatsinda atandukanye mubihe bitandukanye byo gukiza kumiterere yubukorikori bwa ceramic tile.Ingaruka yibiri muri DS na MS ku gushushanya imbaraga za ceramic tile yometse ku bushyuhe bwicyumba.

HPMC ni ether ikomatanya, kugirango dushyire hamwe imibare yombi, kuri HPMC, hagomba kubaho urwego rwo gutanga, kugirango tumenye neza ko amazi ashobora gukemuka no kohereza, tuzi ko ibikubiye mubisimburanya nabyo bigena ubushyuhe bwa gel bwa HPMC , aribyo kumenya ikoreshwa ryibidukikije bya HPMC, Muri ubu buryo, ibikubiye mu matsinda ya HPMC byakozwe mu ntera.Muri uru rwego, uburyo bwo guhuza imikorere na hydroxypropoxy kugirango tugere ku ngaruka nziza ni ibikubiye mu bushakashatsi bwacu.Mu ntera runaka, kwiyongera kwibintu bya mikorerexy bizaganisha kumurongo wo hasi wo gushushanya imbaraga, mugihe kwiyongera kwibintu bya hydroxypropoxy bizaganisha kumurongo wo gushushanya imbaraga.Hariho ingaruka zisa nigihe cyo gufungura.
