Isima nimwe mubikoresho byubaka bikoreshwa cyane mubwubatsi, kandi imikorere ya sima nikintu gikomeye kigira ingaruka mubikorwa byubwubatsi, inzira nibikorwa byanyuma. Kugirango tunoze imikorere ya sima, imvange zitandukanye zongerwaho kenshi kuri sima. Muri bo,hydroxypropyl methylcellulose (HPMC), nkibisanzwe bikoreshwa muri sima, bigira uruhare runini.
(1) Ibintu shingiro bya HPMC
HPMC (Hydroxypropyl Methylcellulose)ni amazi ya elegitoronike ya polymer ikoreshwa cyane mubwubatsi, gutwikira, imiti, ibiryo nizindi nganda. Muri sima, HPMC isanzwe ikoreshwa nkibibyimbye, bigumana amazi hamwe noguhindura rheologiya kugirango iteze imbere amazi ya sima, gutinda gushiraho sima no kunoza imikorere ya sima. Binyuze mu miterere yihariye ya HPMC, HPMC irashobora gukorana na molekile zamazi nuduce twinshi muri sima, bityo bikazamura imikorere ya sima.
(2) Ingaruka za HPMC kubikorwa bya sima
Imikorere ya sima ikubiyemo ibintu byinshi, icyingenzi muri byo ni amazi, guhindagurika no gukora bya sima ya sima mugihe cyo kubaka. HPMC irashobora kunoza cyane imikorere ya sima mubice byinshi.
1. Kunoza amazi ya sima
Amazi ya sima bivuga ubushobozi bwa paste ya sima itemba mubwisanzure mugihe cyo kubaka. Isima ya sima ifite amazi mabi bizatera ibibazo nkingorabahizi zo kuvanga no gukoreshwa muburyo butandukanye mugihe cyubwubatsi, bizagira ingaruka kumyubakire ningaruka. HPMC ifite umubyimba mwiza cyane kandi irashobora kongera neza ububobere bwa sima. Imiterere y'urunigi rwa molekile irashobora gukorana na molekile y'amazi hamwe na sima kugirango ibe imiterere y'urusobekerane rwiza cyane, bityo itume amazi atemba.
Muguhindura ingano ya HPMC yongeweho, amazi ya sima ya sima arashobora kugenzurwa kuburyo bworoshye, ntibishobora gusa kunoza amazi, ariko kandi birinda gutandukana gutinda no gutuzwa biterwa no gutemba gukabije. Kubwibyo, gukoresha HPMC birashobora gufasha kubona ibintu bihamye kandi bihamye mugihe cyo kubaka sima, bityo ubwiza bwubwubatsi.
2. Gutinza igihe cyambere cyo gushiraho sima
Igihe cyambere cyo gushiraho sima bivuga igihe sima itangiye gukomera. Niba igihe cyambere cyo gushiraho ari gito cyane, bizatuma sima igora gukora mugihe cyubwubatsi kandi bigira ingaruka kumyubakire; niba igihe cyambere cyo gushiraho ari kirekire cyane, birashobora gutera gutakaza amazi no kugabanya imbaraga za sima. Nkumubyimba mwinshi kandi ugumana amazi, HPMC irashobora gutinza gahunda yo gufata amazi ya sima muguhuza nubushyuhe buri muri sima, bityo bikongerera igihe cyambere cyo gushiraho. Mugucunga umubare wa HPMC wongeyeho, igihe cyambere cyo gushiraho sima irashobora guhinduka neza kugirango harebwe imikorere ihagije ya sima mugihe cyubwubatsi.
3. Kunoza uburyo bwo gufata amazi ya sima
Isima ikeneye kugumana urugero runaka rwubushuhe mugihe cyubwubatsi kugirango habeho iterambere ryimyitwarire myiza. Iyo gufata amazi ya sima ari bibi, amazi azashira vuba, biganisha ku bibazo nko guturika no kugabanya imbaraga za paste ya sima. Nka polymer, HPMC irashobora gukora imiyoboro ya "hydrogel" imeze nkurusobekerane rwa sima kugirango rushobore gutunganya neza amazi mumashanyarazi, bityo bigatezimbere neza amazi ya sima. Mugihe amazi meza yatunganijwe neza, sima ya sima irahagaze neza mugihe cyubwubatsi, bikagabanya kugabanuka kwa sima, gucamo nibindi bibazo.
4. Kunoza imvugo ya sima
Rheologiya bivuga ibiranga ibikoresho bigenda bihindagurika mukibazo, mubisanzwe birimo ubukonje, amazi, nibindi. Muri sima ya sima, imiterere myiza ya rheologiya ifasha kunoza imikorere yubwubatsi bwa sima.HPMCihindura imiterere ya rheologiya ya sima ya sima kugirango slurry igire amazi meza kandi irwanya umuvuduko muke. Ibi ntibifasha gusa kunoza imikorere no gutwikira sima gusa, ahubwo bifasha no kugabanya igihombo cyibikoresho biterwa nubukonje bukabije bwibishishwa mugihe cyubwubatsi.
5. Kunoza uburyo bwo guhangana na sima
Kwiyongera kwa HPMC birashobora kunoza imbaraga zo guhuza no kurwanya sima. Nyuma yo gukomera kwa sima, imiterere ya fibrous yakozwe na HPMC irashobora kugabanya ibice biterwa nibintu nko kugabanuka kwumye hamwe nubushyuhe bwubushyuhe muri sima kurwego runaka, bityo bikazamura ubukana bwa sima. Cyane cyane iyo wubatse mubidukikije bigoye nkubushyuhe bwo hejuru nubushuhe bwinshi, ikoreshwa rya HPMC rirashobora kugabanya cyane kugaragara kwimvune, bityo bikazamura ubwiza rusange bwimiterere.
(3) Gukoresha ingero za HPMC muri sima
Amashanyarazi yumye: HPMC ikoreshwa cyane muri minisiteri yumye. Irashobora kunoza cyane imikorere ya minisiteri, kongera gufata amazi no gutinza igihe cyambere cyo gushiraho. Mu bikoresho byo kubaka nk'urukuta rwo hanze, ibifata neza, hamwe na pompe ya pompe, umubare wa HPMC wongeyeho ni hagati ya 0.1% na 0.3%. Irashobora kwemeza ko minisiteri itoroshye gukama mugihe cyubwubatsi kandi ikubaka neza.
Kwisunga-sima: Kwisunga-sima ni ibikoresho bya sima bifite amazi meza kandi yuzuye. Bikunze gukoreshwa muburinganire bwubutaka, gusana nindi mishinga. Nkumubyimba mwinshi kandi ugumana amazi, HPMC irashobora kunonosora rheologiya ya sima iringaniza, bigatuma byoroha gukora kandi bigahinduka kimwe mugihe cyo kubaka.
Gusana sima: Mubikoresho byo gusana sima, HPMC irashobora kunoza imiterere no gutuza kwibikoresho, ikabuza ibikoresho gukama vuba kandi byongera imikorere yibikoresho byo gusana.
Nka sima yingenzi ivangwa na sima, HPMC itezimbere cyane imikorere ya sima kandi ikazamura imikorere yubwubatsi nubwiza bwumushinga binyuze mumirimo myinshi nko kubyimba, gufata amazi, no kudindiza gushiraho. Gukoresha muri sima ya sima ntibitezimbere gusa kandi byongerera igihe cyambere cyo gushiraho, ariko kandi byongera gufata amazi, kurwanya ibimeneka hamwe nimiterere ya rheologiya. Mugihe inganda zubwubatsi zikomeje kunoza ibyo zisabwa kugirango ubwubatsi bunoze kandi bunoze, HPMC, nk’inyongeramusaruro y’ubukungu n’ibidukikije, izakoreshwa cyane muri sima nibindi bikoresho byubaka.
