Gushyira ifu mu ifu ya putty akenshi bivuga ko ubuso bw'ipfundo rya putty buhinduka ifu hanyuma bukagwa nyuma yo kubaka, ibyo bizagira ingaruka ku mbaraga z'ipfundo ndetse no ku kuramba kwa putty. Iki gikorwa cyo gushyira ifu gifitanye isano n'ibintu byinshi, kimwe muri byo ni ikoreshwa n'ubwiza bwa hydroxypropyl methylcellulose (HPMC) mu ifu ya putty.
1. Uruhare rwa HPMC mu ifu ya putty
HPMC, nk'inyongera ikoreshwa cyane, ikoreshwa cyane mu bikoresho by'ubwubatsi, harimo ifu ya putty, mortier, kole, nibindi. Imirimo yayo y'ingenzi irimo:
Ingaruka zo gukomera: HPMC ishobora kongera imiterere y'ifu ya putty, bigatuma inyubako irushaho kuba nziza kandi ikirinda kunyerera cyangwa gutemba kw'ifu ya putty mu gihe cyo kubaka.
Kubika amazi: HPMC ifite ubushobozi bwo kubika amazi neza, bishobora kongera ubushobozi bwo gukora kw'ifu ya putty no gukumira putty kubura amazi vuba cyane mu gihe cyo kuma, bigatuma icika cyangwa igacika.
Gufata neza: HPMC ishobora kongera uburyo ifu ya putty ifatana, ku buryo ishobora gufatana neza n'urukuta cyangwa ikindi gice cy'ubutaka, bigabanye ibibazo nko gupfuka no kugwa.
Kunoza imikorere y'ubwubatsi: Kongera HPMC mu ifu ya putty bishobora kongera ubushyuhe n'ubukonje bw'ubwubatsi, bigatuma imirimo y'ubwubatsi irushaho kuba myiza, kandi bikagabanya imyanda.
2. Impamvu zo gusya ifu ya putty
Gusya ifu ya putty ni ikibazo gikunze kubaho bitewe n'impamvu zikomeye, zishobora kuba zifitanye isano n'ibintu bikurikira:
Ikibazo cy’ubutaka: Amazi anyurwa n’ubutaka aba akomeye cyane, bigatuma icyuma gitakaza ubushuhe vuba cyane kandi kigakomera ku buryo budahagije, bigatuma gishonga.
Ikibazo cya formula ya putty: Formula idakwiye ya putty, urugero nk'ingano idasanzwe y'ibikoresho bikoresha sima (nka sima, gypsum, nibindi), izagira ingaruka ku bukomezi no kuramba kwa putty.
Ikibazo cy’inyubako: Kubaka ibintu mu buryo butari bwiza, ubushyuhe bwinshi cyangwa ubushuhe buke bishobora gutuma ifu ya putty ishonga mu gihe cyo kumisha.
Kutabungabunga neza: Kutabungabunga putty ku gihe nyuma yo kubaka cyangwa gukomeza igikorwa gikurikira mbere y'igihe bishobora gutuma ifu ya putty ishonga itaranutse burundu.
3. Isano iri hagati ya HPMC no gusya
Nk'ikintu gikomeza ubushyuhe n'amazi, imikorere ya HPMC mu ifu ya putty igira ingaruka zitaziguye ku bwiza bwa putty. Ingaruka za HPMC ku ifu zigaragarira ahanini muri ibi bikurikira:
(1) Ingaruka zo kubika amazi
Gushyira ifu y'ifu ya putty akenshi bifitanye isano no guhumeka kw'amazi mu ifu. Iyo ingano ya HPMC yongewemo idahagije, ifu ya putty itakaza amazi vuba cyane mu gihe cyo kumisha kandi ntiyongere gukomera, bigatuma ifu yo hejuru ikomeza kuba ifu. Imiterere y'amazi ya HPMC ifasha putty kugumana ubushuhe bukwiye mu gihe cyo kumisha, bigatuma putty ikomeza gukomera buhoro buhoro no gukumira ifu iterwa no kubura amazi vuba. Kubwibyo, kubika amazi kwa HPMC ni ingenzi mu kugabanya ifu.
(2) Ingaruka z'ingaruka zo gukuba
HPMC ishobora kongera imiterere y'ifu ya putty, ku buryo putty ishobora gufatanywa neza n'umubumbe. Iyo ubwiza bwa HPMC ari bubi cyangwa ikoreshejwe nabi, bigira ingaruka ku miterere y'ifu ya putty, bigatuma amazi yayo arushaho kuba mabi, bigatuma ubugari bwayo bugabanuka kandi bugatandukana mu gihe cyo kubaka, ibyo bikaba byatuma ifu ya putty yumuka vuba cyane aho iherereye, bityo bigatera ifu. Byongeye kandi, gukoresha HPMC cyane bizatuma ubuso bw'ifu ya putty burushaho kuba bwiza nyuma yo kubaka, bigira ingaruka ku gufatana kw'igitambaro no gutera ifu ku buso.
(3) Guhuza ibikoresho n'ibindi bikoresho
Mu ifu ya putty, HPMC ikoreshwa hamwe n'ibindi bikoresho bikoresha sima (nka sima, gypsum) n'ibirungo (nk'ifu ya kalisiyumu nyinshi, ifu ya talcum). Ingano ya HPMC ikoreshwa hamwe n'imikoranire yayo n'ibindi bikoresho bigira ingaruka zikomeye ku mikorere rusange ya putty. Ifuru idakwiye ishobora gutuma ifu ya putty itagira imbaraga zihagije ndetse amaherezo igatera ifu. Gukoresha HPMC neza bishobora gufasha kunoza imikorere n'imbaraga bya putty no kugabanya ikibazo cyo gukurura ifu giterwa n'ibikoresho bidahagije cyangwa bidafite sima.
4. Ibibazo by'ubuziranenge bwa HPMC bituma habaho ifu
Uretse ingano ya HPMC ikoreshwa, ubwiza bwa HPMC ubwayo bushobora no kugira ingaruka ku mikorere y'ifu ya putty. Niba ubwiza bwa HPMC butari ku rwego rwo hejuru, nko kuba selulose nkeya kandi amazi akaba make, bizagira ingaruka zitaziguye ku mikorere y'amazi, imikorere y'ubwubatsi n'imbaraga z'ifu ya putty, kandi byongera ibyago byo gukururwa n'ifu. HPMC iri hasi ntabwo igoye gusa gutanga ingaruka nziza zo kugumana amazi no gukomera, ahubwo ishobora no gutera gucika kw'ubuso, gukururwa n'ibindi bibazo mu gihe cyo kumisha putty. Kubwibyo, guhitamo HPMC nziza ni ingenzi kugira ngo wirinde ibibazo byo gukururwa n'ifu.
5. Ingaruka z'ibindi bintu ku ifu
Nubwo HPMC igira uruhare runini mu ifu ya putty, ifu ikunze kuba ingaruka z'ibintu byinshi. Ibintu bikurikira nabyo bishobora gutera ifu:
Imiterere y'ibidukikije: Iyo ubushyuhe n'ubushuhe by'aho bubaka biri hejuru cyane cyangwa hasi cyane, bizagira ingaruka ku muvuduko w'umuvuduko w'ifu ya putty ndetse n'ingaruka za nyuma zo kuyikuraho.
Gutunganya ibintu mu buryo budakwiye: Iyo ibintu bidasukuye cyangwa ubuso bw'ibintu bugafata amazi menshi, bizagira ingaruka ku buryo ifu ya putty ifatana kandi bigatera ifu.
Ifu ya putty idafite ishingiro: Hakoreshwa HPMC nyinshi cyane cyangwa nke cyane, kandi ikigereranyo cy'ibikoresho bitera sima ntigikwiye, ibyo bigatuma ifu ya putty idafata neza kandi ikagira imbaraga nke, bityo bigatuma ifu ihinduka.
Uburyo ifu ya putty ikoreshwa mu gusya ifu ifitanye isano rya bugufi n'ikoreshwa rya HPMC. Akamaro nyamukuru ka HPMC mu ifu ya putty ni ukubika amazi no kuyagwingira. Gukoresha neza bishobora gukumira ifu. Ariko, ifu ikoreshwa mu gusya ntiterwa gusa na HPMC, ahubwo iterwa n'ibintu nk'uburyo ifu ya putty ikoreshwa mu gusya ifu, uburyo ikoreshwa mu gutunganya ifu, n'aho ikoreshwa mu kubaka. Kugira ngo hirindwe ikibazo cyo gusya ifu, ni ngombwa kandi guhitamo HPMC nziza, igishushanyo mbonera cy'ifu gikwiye, ikoranabuhanga rya siyansi mu bwubatsi n'ahantu heza ho kubaka.
