Ifu yifu ya putty mubisanzwe yerekeza kubintu byerekana ko hejuru yubuso bwa pouti ihinduka ifu hanyuma ikagwa nyuma yubwubatsi, ibyo bizagira ingaruka kumubano wa putty hamwe nigihe kirekire cyo gutwikira. Iyi poweri yibintu bifitanye isano nibintu byinshi, kimwe murimwe ni ugukoresha nubwiza bwa hydroxypropyl methylcellulose (HPMC) mu ifu yuzuye.
1. Uruhare rwa HPMC mu ifu yuzuye
HPMC, nk'inyongera ikoreshwa cyane, ikoreshwa cyane mubikoresho byo kubaka, harimo ifu ya putty, minisiteri, kole, nibindi. Ibikorwa byayo byingenzi birimo:
Ingaruka yibyibushye: HPMC irashobora kongera ubudahangarwa bwifu yifu, bigatuma ubwubatsi bugenda neza kandi birinda kunyerera cyangwa gutembera kwifu yifu mugihe cyo kubaka.
Kubika amazi: HPMC ifite amazi meza, ashobora kwagura imikorere yifu ya putty kandi ikabuza gushira gutakaza amazi vuba mugihe cyumye, bikaviramo gucika cyangwa kugabanuka.
Kunonosora neza: HPMC irashobora kongera ifu yifu ya putty, kugirango irusheho gukomera kurukuta cyangwa hejuru yubutaka, kugabanya ibibazo nkibibazo nko gutoboka no kugwa.
Kunoza imikorere yubwubatsi: Kongera HPMC kumafu yifu birashobora kunoza ubworoherane na plastike yubwubatsi, gukora ibikorwa byubwubatsi neza, no kugabanya imyanda.
2. Impamvu zo gushira ifu ya pulverisation
Ifu ya powder pulverisation nikibazo gisanzwe hamwe nimpamvu zitoroshye, zishobora kuba zifitanye isano nibi bikurikira:
Ikibazo cya Substrate: Kwinjiza amazi ya substrate birakomeye cyane, bigatuma putty itakaza amazi vuba kandi igakomera bituzuye, bikaviramo pulverisation.
Ikibazo cya formulaire: Ifu idakwiye yifu ya putty, nkigipimo kidafite ishingiro cyibikoresho bya sima (nka sima, gypsumu, nibindi), bizagira ingaruka kumbaraga no kuramba kwa putty.
Ikibazo cyubwubatsi: Kubaka bidasanzwe, ubushyuhe bwibidukikije cyangwa ubuhehere buke bishobora nanone gutuma ifu yimbuto ihinduka mugihe cyo kumisha.
Kubungabunga bidakwiye: Kunanirwa gukomeza gushira mugihe cyubwubatsi cyangwa gukomeza imburagihe mugihe gikurikira birashobora gutuma ifu yimbuto ihindagurika itumye.
3. Isano iri hagati ya HPMC na pulverisation
Nkumubyimba mwinshi kandi ugumana amazi, imikorere ya HPMC mumafu ya putty igira ingaruka itaziguye kumiterere ya putty. Ingaruka za HPMC kuri poro zigaragarira cyane cyane mubice bikurikira:
(1) Ingaruka zo gufata amazi
Ifu yifu ya putty akenshi ifitanye isano no guhumuka vuba kwamazi muri putty. Niba ingano ya HPMC yiyongereye idahagije, ifu ya putty itakaza amazi vuba mugihe cyo kumisha kandi ikananirwa gukomera neza, bikavamo ifu yubutaka. Umutungo wo kubika amazi ya HPMC ufasha putty kugumana ubuhehere bukwiye mugihe cyo kumisha, bigatuma ibishishwa bikomera buhoro buhoro kandi bikarinda ifu iterwa no gutakaza amazi vuba. Kubwibyo, kubika amazi ya HPMC ni ngombwa kugirango ugabanye ifu.
(2) Ingaruka zingaruka
HPMC irashobora kongera ubudahangarwa bwifu ya putty, kugirango putty irusheho guhuzwa na substrate. Niba ubwiza bwa HPMC ari bubi cyangwa bukoreshejwe nabi, bizagira ingaruka ku guhuza ifu ya putty, bigatuma amazi yayo arushaho kuba bibi, bikavamo ubusumbane nubunini butaringaniye mugihe cyubwubatsi, bishobora gutuma ifu yimbuto yumishwa vuba vuba, bityo gutera ifu. Byongeye kandi, gukoresha cyane HPMC bizanatera ubuso bwifu ya putty kuba yoroshye nyuma yubwubatsi, bigira ingaruka kumyifatire hamwe no gutera ifu yubutaka.
(3) Gukorana nibindi bikoresho
Mu ifu yuzuye, HPMC isanzwe ikoreshwa hamwe nibindi bikoresho bya sima (nka sima, gypsumu) hamwe nuwuzuza (nk'ifu ya calcium iremereye, ifu ya talcum). Ingano ya HPMC yakoreshejwe hamwe nubufatanye bwayo nibindi bikoresho bigira ingaruka zikomeye kumikorere rusange ya putty. Amata adafite ishingiro arashobora kuganisha ku mbaraga zidahagije zifu yifu hanyuma amaherezo iganisha ku ifu. Gukoresha neza HPMC birashobora gufasha kunoza imikorere ihuza imbaraga nimbaraga za putty no kugabanya ikibazo cyifu yatewe nibikoresho bidahagije cyangwa bingana.
4. Ibibazo byubuziranenge bwa HPMC biganisha ku ifu
Usibye ingano ya HPMC yakoreshejwe, ubwiza bwa HPMC ubwabwo bushobora no guhindura imikorere yifu ya putty. Niba ubwiza bwa HPMC butujuje ubuziranenge, nk'ubuziranenge bwa selile nkeya ndetse n’imikorere idahwitse y’amazi, bizagira ingaruka ku buryo butaziguye kubika amazi, imikorere yubwubatsi nimbaraga zifu yifu, kandi byongera ibyago byo kumena ifu. HPMC yo hasi ntabwo igoye gusa gutanga amazi meza hamwe ningaruka zibyibushye, ariko irashobora no gutera hejuru yubutaka, ifu nibindi bibazo mugihe cyumye cyo gushira. Kubwibyo, guhitamo ubuziranenge bwa HPMC ningirakamaro kugirango wirinde ibibazo byifu.
5. Ingaruka zindi mpamvu kuri poro
Nubwo HPMC igira uruhare runini mu ifu yuzuye, ifu isanzwe nigisubizo cyingaruka ziterwa nibintu byinshi. Ibintu bikurikira birashobora kandi gutera ifu:
Ibidukikije: Niba ubushyuhe nubushuhe bwibidukikije byubatswe ari hejuru cyane cyangwa biri hasi cyane, bizagira ingaruka kumuvuduko wumuti ningaruka zanyuma zo gukiza ifu yimbuto.
Kuvura insimburangingo idakwiye: Niba insimburangingo idafite isuku cyangwa ubuso bwa substrate bwinjiza amazi menshi, bizagira ingaruka kumyifatire yifu yifu kandi bitera ifu.
Ifu ya putty idafite ishingiro: HPMC irakoreshwa cyane cyangwa nto cyane, kandi igipimo cyibikoresho bya sima ntigikwiye, ibyo bigatuma habaho gufatana hamwe nimbaraga zifu yifu, bityo bigatera ifu.
Ifu yerekana ifu yifu ifitanye isano rya hafi no gukoresha HPMC. Igikorwa nyamukuru cya HPMC mumashanyarazi ni kubika amazi no kubyimba. Gukoresha neza birashobora gukumira neza ko habaho ifu. Ariko, kuba ifu ibaho ntibiterwa na HPMC gusa, ahubwo biterwa nibintu nka formula yifu yifu, kuvura insimburangingo, hamwe nubwubatsi. Kugirango wirinde ikibazo cyifu yifu, ni ngombwa kandi guhitamo HPMC yujuje ubuziranenge, igishushanyo mbonera cyiza, ikoranabuhanga ryubaka siyanse hamwe n’ibidukikije byiza byubaka.
