Amashanyarazi avanze yerekana ibintu bya sima, igiteranyo cyiza, ivangwa, amazi nibindi bice byagenwe ukurikije imikorere. Ukurikije igipimo runaka, nyuma yo gupimwa no kuvangwa muri sitasiyo ivanga, ijyanwa aho ikoreshwa n'ikamyo ivanga. Bika imvange ya minisiteri mu kintu cyihariye kandi uyikoreshe mugihe cyagenwe. Ihame ryakazi rya minisiteri ivanze-isa na beto yubucuruzi, kandi sitasiyo yubucuruzi ivanze irashobora icyarimwe kubyara minisiteri ivanze.
1. Ibyiza bya minisiteri ivanze
1) Amabuye avanze n’amazi arashobora gukoreshwa mu buryo butaziguye nyuma yo kujyanwa aho atabanje gutunganyirizwa, ariko minisiteri igomba kubikwa mu kintu cyangiza ikirere;
2) Amabuye avanze n’amazi ategurwa mu ruganda rwumwuga, rufasha kugenzura no kugenzura ubwiza bwa minisiteri;
3) Guhitamo ibikoresho fatizo bya minisiteri ivanze ni nini. Igiteranyo gishobora kuba cyumye cyangwa gitose, kandi ntigikeneye gukama, bityo igiciro gishobora kugabanuka. Byongeye kandi, umubare munini wumucanga wimashini yubukorikori ikorwa n’imyanda yo mu nganda nk ivu ry’isazi n’imyanda ikomeye y’inganda nkibyuma by’icyuma n’umurizo w’inganda birashobora kuvangwa, ntibizigama umutungo gusa, ahubwo binagabanya igiciro cya minisiteri.
4) Ahantu hubatswe hafite ibidukikije byiza kandi bitanduye cyane.
2. Ingaruka za minisiteri ivanze
1) Kubera ko minisiteri ivanze n’amazi ivanze n’amazi mu ruganda rutanga umusaruro wabigize umwuga, kandi ubwikorezi ni bunini icyarimwe, ntibushobora kugenzurwa mu buryo bworoshye ukurikije aho ubwubatsi bukoreshwa n’imikoreshereze. Byongeye kandi, minisiteri ivanze n’amazi igomba kubikwa mu kintu cyumuyaga nyuma yo kujyanwa ahazubakwa, bityo hagomba gushyirwaho icyuzi cy’ivu;
2) Igihe cyo gutwara kibujijwe nuburyo bwimodoka;
3) Kubera ko minisiteri ivanze itose ibitswe ahazubakwa umwanya muremure ugereranije, haribisabwa bimwe mubikorwa, gushiraho igihe no gutuza kumikorere ya minisiteri.
Hydroxypropyl methylcellulose ikoreshwa nkigikoresho cyo kubika amazi no kubika minisiteri ya sima kugirango minomeri ishoboke. Ikoreshwa nka binder mugupompa plaster, itezimbere ikwirakwizwa kandi ikongerera igihe cyakazi. Imikorere yo gufata amazi ya hydroxypropyl methylcellulose HPMC irinda guturika guturika bitewe no gukama vuba nyuma yo kuyisaba, kandi ikongerera imbaraga nyuma yo gukomera. Kubika amazi nigikorwa cyingenzi cya hydroxypropyl methylcellulose HPMC, kandi nigikorwa kandi benshi mubakora uruganda rukora amavuta avanze na minisiteri. Ibintu bigira ingaruka ku gufata amazi ya minisiteri ivanze n’amazi arimo ingano ya HPMC yongeyeho, ubwiza bwa HPMC, ubwiza bw’ibice, hamwe nubushyuhe bw’ibidukikije.
Nyuma ya minisiteri ivanze n’amazi ajyanwa ku rubuga, igomba kubikwa mu kintu kitarimo umwuka. Niba uhisemo icyuma, ingaruka zo kubika ninziza, ariko ishoramari ni ryinshi cyane, ridafasha kumenyekanisha no kubishyira mubikorwa; urashobora gukoresha amatafari cyangwa amabuye kugirango wubake ikidendezi cyivu, hanyuma ukoreshe minisiteri idafite amazi (igipimo cyo gufata amazi kiri munsi ya 5%) kugirango uhomye hejuru, kandi ishoramari ni rito. Ariko rero, guhomesha minisiteri idafite amazi ni ngombwa cyane, kandi hagomba kubahirizwa ubwiza bw’ubwubatsi bw’amazi adafite amazi. Nibyiza kongeramo hydroxypropyl methylcellulose ibikoresho bya HPMC kuri minisiteri kugirango bigabanye ibisasu bya minisiteri. Icyuzi cya ivu kigomba kugira ahantu hahanamye kugirango hasukure byoroshye. Icyuzi cy'ivu kigomba kugira igisenge gifite ahantu hahagije kugirango kirinde imvura n'izuba. Iyo minisiteri ibitswe muri pisine, kandi hejuru yikidendezi cy ivu hagomba gutwikirizwa imyenda ya pulasitike kugirango barebe ko iyo minisiteri ifunze.
Uruhare rukomeye rwa hydroxypropyl methylcellulose HPMC muri minisiteri ivanze cyane cyane ifite ibintu bitatu, kimwe nubushobozi buhebuje bwo gufata amazi, ikindi ni ingaruka ku guhuza hamwe na thixotropy ya minisiteri ivanze, naho icya gatatu ni imikoranire na sima. Ingaruka yo gufata amazi ya selile ya selile biterwa no kwinjiza amazi kurwego rwibanze, imiterere ya minisiteri, ubunini bwikigero cya minisiteri, amazi akenerwa na minisiteri, nigihe cyo kugenera ibikoresho. Iyo hejuru ya hydroxypropyl methylcellulose, niko gufata amazi neza.
Ibintu bigira ingaruka ku kugumana amazi ya minisiteri ivanze harimo selile ya ether viscosity, umubare wongeyeho, ubwiza bwibice no gukoresha ubushyuhe. Ninini cyane ya selulose ether, niko gukora neza amazi. Viscosity nikintu cyingenzi cyimikorere ya HPMC. Kubicuruzwa bimwe, ibisubizo bya viscosity byapimwe nuburyo butandukanye biratandukanye cyane, ndetse bimwe byikubye kabiri itandukaniro. Kubwibyo, mugihe ugereranije viscosity, bigomba gukorwa hagati yuburyo bumwe bwo gupima, harimo ubushyuhe, rotor, nibindi.
Muri rusange, uko ubukonje buri hejuru, ningaruka nziza yo gufata amazi. Nyamara, uko hejuru yubukonje nuburemere bwa molekuline ya HPMC, kugabanuka gukwiranye kwayo bizagira ingaruka mbi kumbaraga no mumikorere yubwubatsi. Iyo hejuru yubukonje, niko bigaragara ingaruka zo kubyimba kuri minisiteri, ariko ntabwo ihwanye neza. Iyo hejuru yubusembwa, niko amabuye atose azarushaho kuba meza, ni ukuvuga mugihe cyubwubatsi, bigaragarira nko kwizirika kuri scraper no gufatira hejuru kuri substrate. Ariko ntabwo ari byiza kongera imbaraga zimiterere ya minisiteri yonyine. Mugihe cyo kubaka, imikorere irwanya sag ntabwo igaragara. Ibinyuranye na byo, hydroxypropyl methylcellulose yahinduwe hamwe na viscosity yo hagati kandi ntoya ifite imikorere myiza mugutezimbere imbaraga zububiko bwa minisiteri.
Muri minisiteri ivanze neza, ingano ya selile ya ether HPMC ni mike cyane, ariko irashobora kunoza cyane imikorere yubwubatsi bwa minisiteri ivanze, kandi ninyongera nyamukuru igira ingaruka kumyubakire ya minisiteri. Guhitamo neza hydroxypropyl methylcellulose ifite uruhare runini mugutezimbere imikorere ya minisiteri ivanze.
