Ifu yuzuye ni ibikoresho byubaka bikoreshwa cyane cyane bikozwe muri gypsumu nibindi byongerwaho. Ikoreshwa mukuzuza icyuho, ikidodo hamwe nibisakara murukuta no hejuru. Hydroxypropylmethylcellulose (HPMC) ni imwe mu nyongeramusaruro ikoreshwa cyane mu ifu ya putty. Ifite uburyo bwiza bwo gufata amazi no gufatana neza, bishobora kuzamura imikorere n'imbaraga za putty. Nyamara, ubwiza bwa selile ya HPMC bushobora guterwa nimpamvu zitandukanye, nko guhagarika umutima no guhindagurika.
Gukangura ni intambwe yingenzi mugutegura ifu yuzuye. Iremeza ko ibiyigize byose bigabanijwe neza kandi ko ibicuruzwa byanyuma bitarimo ibibyimba nibindi bidasanzwe. Ariko, imyigaragambyo ikabije irashobora gutuma habaho selile mbi ya HPMC. Imyivumbagatanyo ikabije irashobora gutuma selile isenyuka, bikagabanya gufata amazi hamwe nibiranga. Nkigisubizo, putty ntishobora kwizirika neza kurukuta kandi irashobora gucika cyangwa gukuramo nyuma yo kubisaba.
Kugira ngo wirinde iki kibazo, ni ngombwa cyane gukurikiza amabwiriza yabakozwe yo kuvanga ifu yuzuye. Mubisanzwe, amabwiriza azagaragaza umubare wamazi ukwiye nigihe cyo guhagarika umutima. Byiza, putty igomba gukangurwa neza kugirango ibone uburyo bworoshye kandi buhoraho utabanje kumena selile.
Kunanuka ni ikindi kintu cyingenzi kigira ingaruka kumiterere ya selile ya HPMC muri poro. Gukoresha bivuga kongeramo amazi cyangwa andi mashanyarazi kuri putty kugirango byoroshye gukwirakwira no kubaka. Ariko, kongeramo amazi menshi bizagabanya selile kandi bigabanye uburyo bwo kubika amazi. Ibi birashobora gutuma ibishishwa byuma vuba, bigatera gucika no kugabanuka.
Kugira ngo wirinde iki kibazo, ni ngombwa gukurikiza amabwiriza yakozwe nuwagabanije ifu ya putty. Mubisanzwe, amabwiriza azagaragaza umubare ukwiye wamazi cyangwa umusemburo wo gukoresha nigihe cyo kuvanga. Birasabwa kongeramo amazi make gahoro gahoro hanyuma ukavanga neza mbere yo kongeramo. Ibi bizemeza ko selile ikwirakwizwa neza muri putty kandi ikagumana imiterere yabyo.
Kurangiza, gukurura no kuyungurura bizagira ingaruka kumiterere ya selile ya HPMC mumashanyarazi. Ni ngombwa gukurikiza amabwiriza yakozwe nuwabikoze yitonze kugirango selile igumane amazi kandi agumya. Mugukora ibi, umuntu arashobora kubona ubuziranenge bwo hejuru buzatanga ibisubizo byiza kandi byemeza igihe kirekire kandi gihamye.
