Hydroxypropyl methylcellulose (HPMC), nk'imwe muri ethers z'ingenzi cyane za cellulose mu buryo bwa none bwa mortier yumye, igira uruhare rudasimburwa mu matiles ateye. Bitewe n'ubwinshi bw'amatiles bugenda bwiyongera, imiterere y'inyubako irushaho gukomera, ndetse no kunoza buri gihe amahame y'imbaraga zo gufatanya, imikorere ya HPMC mu buryo bwo gukora irushaho kuba ingenzi. Byaba ari amatiles yo mu bwoko bwa C1/C2 cyangwa sisitemu zo gufatanya zikora neza ku matiles aremereye, amatiles manini, n'amatiles adafata amazi menshi, HPMC igira uruhare runini mu kunoza ubushobozi bwo gukora, kongera igihe cyo kuramba, no kongera imbaraga zo gufatanya.
1. Kunoza uburyo amazi abikwa kugira ngo amazi abe meza
Kole zo mu mabati ni za mortilari ntoya, zifite ubugari busanzwe bwa mm 3–5. Zishobora gutakaza amazi vuba bitewe n’amazi yihuta anyurwa n’ubutaka, ubushyuhe bwinshi, cyangwa umuyaga utuma amazi yumuka.
HPMC ifunga amazi neza binyuze mu gukora urusobe rw'amazi menshi muri morti, bikongera cyane uburyo amazi abikwamo muri kole. Ubusanzwe, HPMC nziza ishobora kugera ku kigero cyo kubika amazi kingana na 90%–98%.
Ingaruka zo kubika amazi zirimo:
Kugabanya umuvuduko w'amazi muri sima, bikongera imbaraga zo gufatanya;
Gukumira ibura ry'amazi hakiri kare, kwangirika no gucikamo ibice;
Kunoza uburyo amatafari afatanye n'amatafari adafata amazi menshi (nk'amatafari ya porcelain n'amatafari afite glaze).
2. Kunoza imiterere y'indwara z'imitsi no kongera ubushobozi bwo gukora
Gukora neza ni ikimenyetso cy'ingenzi kigaragaza niba kole y'amatafari izemerwa n'amatsinda y'abubatsi. HPMC irushaho kunoza imiterere ya rheological ya sima, bigatuma kole y'amatafari ikwirakwira neza kandi ikagira thixotropy.
Ibimenyetso by'ingenzi by'imiterere y'amaraso mu maraso:
thixotropy nziza: Igabanya ubukana, yoroshye kuyikwirakwiza; ikira vuba nyuma yo guhagarara, nta kuremba.
Gushyira amavuta mu buryo bworoshye: Biroroshya gukoresha trowel, bikongera imikorere myiza mu bwubatsi.
Kunoza uburyo ibirungo bihurirana kandi bigakomera: Birinda ko ibirungo bitandukana, gutandukanya no kuva amaraso.
Ku matiles manini no kubaka amatiles menshi ku nkuta, imiterere ya thixotropic ya HPMC ni ingenzi cyane, ikarinda amatiles kunyerera no kunoza imikorere idaserera ku buso buhagaze.
3. Igihe cyo gufungura cyanogejwe n'igihe cyo kuvugurura
Mu bwubatsi bwa none bwo gufunga amatafari, kongera igihe cyo gufungura binongera imikorere myiza yo gushyiraho amatafari kandi bigabanya gusubiramo imirimo.
HPMC idindiza imyuka y'amazi ava ku buso bwa morti, bigatuma morti ikomeza gutoha kandi igaha abakozi umwanya uhagije wo kurangiza gushyiramo no gutunganya.
Ingaruka zisanzwe:
Igihe cyo gufungura gishobora kongerwa kugeza ku minota 20-30.
Kongera igihe cyo guhindura bifasha gushyira amatafari manini mu mwanya wayo.
HPMC ni inyongeramusaruro y'ingenzi kuri kole zo mu bwoko bwa C2 zikora neza cyane zikenera igihe kirekire cyo gufungura.
4. Ingufu zo kongera ubufatanye n'ubudahangarwa bw'imiterere
HPMC si "igifunga" mu buryo bwa shimi, ariko yongera cyane imbaraga zo gufatanya kw'amatafari binyuze mu kunoza uburyo bwo guhumeka sima, kunoza imiterere ya sima, no kongera ubucucike bwa sima.
Inyongera zirimo:
Kubika amazi bituma amazi arushaho kumera neza, bityo bigatuma habaho gel nyinshi za CSH.
Itunganya imiterere ya mortilage kandi ikongera ubushobozi bwo guhuza hagati y'urukuta.
Birinda icyuho cyo hagati y'urusobe rw'imbere kandi bikongera ireme ry'ubufatanye n'ubudahangarwa.
Ingaruka zabyo zigaragara cyane cyane mu guhuza amatafari afite vitrified n'amatafari adafata amazi menshi.
5. Kurwanya gutembera no kugwa kw'amazi byarushijeho kuba byiza
Ubudahangarwa bwo kunyerera mu gihe cyo gushyiraho amatafari ahagaze ni ikimenyetso cy'ingenzi ku mabati afashe.
Imiterere myinshi ya thixotropic ya HPMC ituma kole y'amatafari yongera gukomera vuba nyuma yo kuyikoresha, bikarinda amatafari kunyerera hasi bitewe n'uburemere bwayo.
Cyane cyane mu kubaka amatafari manini n'amatafari manini afite irangi, HPMC ifite ubukana bwinshi kandi yasimbuwe neza ni ingenzi cyane mu kurwanya kunyerera.
6. Ibyifuzo byo guhitamo igipimo cya HPMC n'uburyo bwo guhitamo ubukana bw'amazi
Mu miterere y’amatafari yo gufunga, ingano ya HPMC muri rusange iba ari nto, ariko ingaruka zayo ni nini.
Umubare usanzwe w'inyongera: 0.2%–0.4%
Ingano yihariye iterwa na: ubwoko bwa sima, igipimo cy'umunyururu, aho bubaka, n'ingano y'amatafari. Ibyifuzo ku bucucike (25°C, 2% by'umuti):
Kole isanzwe yo mu bwoko bwa C1: 40.000–60.000 mPa·s
Kole yo mu bwoko bwa C2 ifite imikorere myiza: 75,000–100,000 mPa·s cyangwa irenga
Kole y'amatafari ku matafari manini: ≥100.000 mPa·s, urwego rwo hejuru rwa thixotropic
HPMC, nk'igikoresho cy'ingenzi mu buryo bwo gufata amatafari, itanga inyungu nyinshi mu bya tekiniki mu kunoza uburyo amazi abikwamo, rheology, imbaraga zo gufatanya, no kudacika intege. Byaba ari ugushyiraho amatafari asanzwe yo ku rukuta no hasi cyangwa gukoresha amatafari manini, guhitamo no gukoresha HPMC nziza ni ingenzi cyane kugira ngo habeho imikorere ihamye yo gufata amatafari n'ubwiza bw'ubwubatsi bwizewe. Ku bakora amatafari bashaka gukora neza, guhitamo urwego rukwiye rwa HPMC ni ngombwa.
