Inganda zubaka zateye intambwe igaragara mumyaka yashize, hibandwa cyane cyane kunoza imikorere, kuramba no kuramba kwibikoresho byubaka. Hydroxypropyl methylcellulose (HPMC) yahindutse inyongeramusaruro nyinshi mubikoresho byubwubatsi bushingiye kuri gypsumu, bitanga inyungu nyinshi zifasha kuzamura ubwiza rusange nubushobozi bwimishinga yubwubatsi.
1. Kunoza imikorere
Imwe mu nyungu zingenzi zo kongeramo HPMC mubwubatsi bwa plasta ni iterambere ryinshi mubikorwa. HPMC ikora nka moderi ihindura imvugo kugirango yongere ubushobozi bwo gufata amazi yimvange ya gypsumu. Ibi bivamo ibintu byoroshye, birashobora gucungwa neza byoroshye kubishyira mu bikorwa no kugabanya imirimo isabwa mugihe cyo kubaka.
2. Kongera imbaraga
HPMC ifasha kunoza imitekerereze ya gypsum ivanze, iteza imbere umubano mwiza hagati yibikoresho na substrate zitandukanye. Ibi nibyingenzi byingenzi muguhomesha no gutanga porogaramu aho gukomera gukomeye ningirakamaro kuramba no gutuza kwubuso bwuzuye. Inkunga yatunganijwe nayo igabanya ubushobozi bwo gucamo no gusiba.
3. Kubika amazi
Kubika amazi nikintu cyingenzi mubikoresho byubaka gypsumu. HPMC yongerera neza ubushobozi bwo gufata amazi yuruvange, ikumira vuba kandi ikanatanga inzira ihamye. Ibi ni ingirakamaro cyane cyane ahantu hahindagurika ikirere, kuko gitanga idirishya ryagutse ryo kubaka no kurangiza.
4. Kugenzura igihe coagulation
Ibikoresho bya Gypsumu akenshi bisaba ibihe byihariye byo gushiraho kugirango ugere ku mbaraga nziza kandi ziramba. HPMC ni retarder yizewe itanga uburyo bwiza bwo kugenzura igihe. Ibi ni ingirakamaro cyane kubikorwa binini byubwubatsi aho umwanya ariwo shingiro, utanga ibintu byoroshye kandi byoroshye kubishyira mubikorwa.
5. Kurwanya ibice
Kumena nikibazo gikunze kuboneka mubwubatsi kandi HPMC igira uruhare runini mugukemura iki kibazo. Mu kongera ubwuzuzanye muri rusange hamwe ningufu zingana za gypsumu ivanze, HPMC ifasha kugabanya imiterere yimvune, kwemeza kuramba nuburinganire bwububiko bwuzuye.
6. Kunoza kuramba
Kwinjiza HPMC muburyo bwa gypsum yifu yongerera cyane igihe kirekire cyibicuruzwa byanyuma. Kongera imbaraga zifatika, kugabanya gucikamo no kugenzura igihe cyo guhuza bihuza kugirango ibikoresho byubaka bihangane nibidukikije hamwe nihungabana ryimiterere, bivamo ubuzima burambye.
7. Gushyira mu bikorwa byinshi
Guhuza HPMC hamwe ninyongeramusaruro zitandukanye nibikoresho byubwubatsi bituma bihinduka cyane. Ihuza bidasubirwaho muburyo bushingiye kuri plaster kandi ifite uburyo bwinshi bwo gukoresha harimo guhomesha, gusimbuka, guhuza hamwe no kwishyiriraho ibiciro. Ubu buryo bwinshi butuma HPMC ihitamo bwa mbere kubasezeranye n'abubatsi bashaka ibisubizo byizewe, byoroshye.
8. Kuramba
Mugihe inganda zubwubatsi ziharanira kugera ku iterambere rirambye, gukoresha inyongeramusaruro zangiza ibidukikije byabaye ngombwa. HPMC ikomoka ku masoko ashobora kuvugururwa kandi igahuza n'intego zirambye z'inganda. Ibinyabuzima byangiza ibidukikije hamwe n’ingaruka nke z’ibidukikije bituma ihitamo ibidukikije byangiza ibidukikije mu mishinga yo kubaka igamije kugabanya ikirere cyazo.
9. Ubwiza buhamye
Imikoreshereze ya HPMC mubwubatsi bwa plaster itanga ubuziranenge buhoraho kandi buteganijwe kubicuruzwa byanyuma. Kugenzura igihe cyagenwe, kunoza imikorere no kongera imbaraga byorohereza porogaramu imwe, kugabanya ubushobozi bwinenge no kudahuza muburyo bwuzuye.
10. Gukoresha ikiguzi
Mugihe ikiguzi cyambere gishobora kwitabwaho, inyungu ndende zo gukoresha HPMC mubwubatsi bwa plasta akenshi ziruta ishoramari. Kongera igihe kirekire no kugabanya gukenera gusanwa cyangwa kubungabungwa bigira uruhare mu kuzigama igihe kirekire, bigatuma uhitamo ubushishozi bwamafaranga kubikorwa byubwubatsi aho kuramba ari ngombwa.
mu gusoza
Mu gusoza, kwinjiza hydroxypropyl methylcellulose (HPMC) mukubaka umukungugu wa gypsumu bizana inyungu nyinshi kugirango uhuze ibikenerwa n’inganda zubaka. Kuva ibikorwa byongerewe imbaraga no gukomera kugeza igihe cyagenwe no kunoza uburyo burambye, HPMC igira uruhare runini mugutezimbere imikorere nubuziranenge bwibikoresho byubaka gypsumu. Mu gihe inganda zikomeje kwakira udushya, HPMC igaragara nk'inyongera yizewe kandi itandukanye igira uruhare mu gutsinda kw'imishinga itandukanye y'ubwubatsi ku isi.
