Sima ivanze n'amazi bivuga ibikoresho bivangwa n'isima, ibintu bito, imvange, amazi n'ibindi bikoresho bitandukanye bigenwa hakurikijwe imikorere. Dukurikije igipimo runaka, nyuma yo gupimwa no kuvangwa mu cyumba cyo kuvanga, ijyanwa aho ikoreshwa n'ikamyo ivangavanga. Bika imvange y'isima mu gikoresho cyihariye hanyuma uyikoreshe mu gihe cyagenwe. Ihame ry'imikorere y'isima ivanze n'amazi risa na sima ikoreshwa mu bucuruzi, kandi ahantu ho kuvanga sima ikoreshwa mu bucuruzi hashobora gukora sima ivanze n'amazi icyarimwe.
1. Ibyiza byo gukoresha sima ivanze n'amazi
1) Imvange y'amazi ishobora gukoreshwa nyuma yo kujyanwa aho ikorerwa idatunganyijwe, ariko imvange igomba kubikwa mu kintu gifunze neza;
2) Sima ivanze n'amazi itegurwa mu ruganda rw'umwuga, ibyo bikaba byiza mu kugenzura no kugenzura ubwiza bwa sima;
3) Amahitamo y'ibikoresho fatizo byo gukoresha sima ivanze n'amazi ni menshi. Ingano ishobora kuba yumye cyangwa itose, kandi ntabwo ari ngombwa ko yumisha, bityo ikiguzi gishobora kugabanuka. Byongeye kandi, umucanga munini w'imashini z'ubukorano ukorwa n'imyanda y'inganda nk'ivu ry'ibihu n'imyanda ikomeye y'inganda nk'ivu ry'icyuma n'imyanda y'inganda ishobora kuvangwa, ibyo bikaba bidakiza gusa umutungo, ahubwo binagabanya ikiguzi cya sima.
4) Ahantu ho kubakwa hari ibidukikije byiza kandi umwanda ugabanuka.
2. Ingaruka mbi zo gukoresha sima ivanze n'amazi
1) Kubera ko imvange y’amazi ivanze n’amazi mu ruganda rw’umwuga, kandi ingano y’ubwikorezi ikaba ari nini icyarimwe, ntishobora kugenzurwa mu buryo bworoshye hakurikijwe aho imirimo y’ubwubatsi igeze n’uko ikoreshwa. Byongeye kandi, imvange y’amazi ivanze n’amazi igomba kubikwa mu gikoresho gifunguye umwuka nyuma yo kujyanwa aho imirimo y’ubwubatsi ibera, bityo ikidendezi cy’ivu kigomba gushyirwa aho hantu;
2) Igihe cyo gutwara abantu kigenwa n'imiterere y'imodoka;
3) Kubera ko sima ivanze n'amazi ibikwa aho bubaka igihe kirekire, hari ibisabwa kugira ngo sima ikore neza, ishyireho igihe n'imikorere ihamye y'iyi sima.
Hydroxypropyl methylcellulose ikoreshwa nk'ikintu gifata amazi kandi kigabanya sima kugira ngo ikoreshwe mu gupompa. Ikoreshwa nk'igikoresho cyo gufunga mu gusigwa, irushaho gukwirakwira no kongera igihe cyo gukora. Imikorere ya hydroxypropyl methylcellulose HPMC irinda amazi gucika bitewe no kuma vuba cyane nyuma yo kuyikoresha, kandi yongera imbaraga nyuma yo gukomera. Kugumana amazi ni imikorere y'ingenzi ya hydroxypropyl methylcellulose HPMC, kandi ni imikorere abakora imashini nyinshi zo mu rugo zivanga amazi bitaho. Ibintu bigira ingaruka ku ngaruka za sima zivanga amazi zirimo ingano ya HPMC yongewemo, ubukana bwa HPMC, ubuto bw'uduce duto, n'ubushyuhe bw'aho ikoreshwa.
Nyuma y’uko imvange y’amazi ivanzwe ijyanwa aho iherereye, igomba kubikwa mu gikoresho kidahumeka. Iyo uhisemo icyuma, ingaruka zo kubika ni nziza, ariko ishoramari ni rinini cyane, ibyo bikaba bidatuma abantu benshi bakwirakwira kandi bagakoresha; ushobora gukoresha amatafari cyangwa ibiti mu kubaka ikigega cy’ivu, hanyuma ugakoresha imvange idahumeka (igipimo cyo kwinjiza amazi kiri munsi ya 5%) kugira ngo ushyireho ibumba, kandi ishoramari ni ryo rito cyane. Ariko, gusiga ibumba ry’ibumba ridahumeka ni ingenzi cyane, kandi ubwiza bw’ibumba ridahumeka rigomba kwemezwa. Ni byiza kongeramo ibikoresho bya hydroxypropyl methylcellulose HPMC kuri icyo gikoresho kugira ngo ugabanye icyuho cyacyo. Ahantu hasi h’ikigega cy’ivu hagomba kuba hari uburebure runaka kugira ngo byoroshye gusukura. Ikigega cy’ivu kigomba kuba gifite igisenge gifite ubuso buhagije bwo kurinda imvura n’izuba. Ibumba ribikwa mu kigega cy’ivu, kandi ubuso bw’ikigega cy’ivu bugomba gupfukwaho igitambaro cya pulasitiki kugira ngo ibumba ribe rifunze neza.
Uruhare rw'ingenzi rwa hydroxypropyl methylcellulose HPMC muri mortilage ivanze amazi rufite ahanini ibintu bitatu, kimwe ni ubushobozi bwiza bwo kubika amazi, ikindi ni ingaruka ku buryo ibintu bihurirana kandi bigahinduka thixotropy ya mortilage ivanze amazi, naho icya gatatu ni uburyo sima ikorana. Ingaruka zo kubika amazi ya eteri ya cellulose ziterwa n'uburyo amazi yinjiye mu gice cy'ibanze, imiterere ya mortilage, ubunini bw'igice cy'urukuta, gukenera amazi kwa mortilage, n'igihe ibikoresho bishyirwa. Uko hydroxypropyl methylcellulose igaragara cyane, ni ko amazi abikwa neza.
Ibintu bigira ingaruka ku kubika amazi kwa mortilage ivanze n’amazi birimo ubushyuhe bwa cellulose ether, ingano y’inyongera, ubushyuhe bw’uduce duto n’ubushyuhe bw’ikoreshwa. Uko ubushyuhe bwa cellulose ether burushaho kuba bwinshi, ni ko imikorere myiza yo kubika amazi. Ubushyuhe ni igipimo cy’ingenzi cy’imikorere ya HPMC. Ku gicuruzwa kimwe, ibisubizo bya viscosity bipimwe hakoreshejwe uburyo butandukanye biratandukanye cyane, ndetse bimwe bifite itandukaniro rya kabiri. Kubwibyo, iyo ugereranije ubushyuhe, bigomba gukorwa hagati y’uburyo bumwe bwo gupima, harimo ubushyuhe, rotor, nibindi.
Muri rusange, uko amazi arushaho kuba menshi, ni ko ingaruka zo kubika amazi ziba nziza. Ariko, uko amazi arushaho kuba menshi kandi uburemere bwa molekile ya HPMC bukarushaho kuba bwinshi, kugabanuka kw'uburyo ishonga bizagira ingaruka mbi ku mbaraga n'imikorere y'ubwubatsi bwa mortika. Uko amazi arushaho kuba menshi, ni ko ingaruka zo gushonga zigaragara ku mortika, ariko ntabwo bingana neza. Uko amazi arushaho kuba menshi, mortika irushaho kuba ndende, ni ukuvuga ko mu gihe cyo kubaka, igaragara nk'aho ifata ku gikoresho gikurura no gufatana cyane n'ubutaka. Ariko ntabwo ari byiza kongera imbaraga z'ubwubatsi bwa mortika itose ubwayo. Mu gihe cyo kubaka, imikorere yo kurwanya gucika ntigaragara. Ahubwo, hydroxypropyl methylcellulose yahinduwe ifite viscosity iri hagati n'iciriritse ifite imikorere myiza mu kunoza imbaraga z'ubwubatsi bwa mortika itose.
Muri mortilla ivanze n'amazi, ingano y'inyongera ya cellulose ether HPMC ni nto cyane, ariko ishobora kunoza cyane imikorere y'ubwubatsi bwa mortilla ivanze n'amazi, kandi ni inyongera nyamukuru igira ingaruka ku mikorere y'ubwubatsi bwa mortilla. Guhitamo neza hydroxypropyl methylcellulose ikwiye bigira ingaruka zikomeye ku kunoza imikorere ya mortilla ivanze n'amazi.
