Imwe muntandukanyirizo nini hagati ya minisiteri yumye ivanze na minisiteri gakondo ni uko minisiteri ivanze yumye ihindurwa hamwe na chimique yongeweho imiti. Ongeraho kimwe cyongewe kumashanyarazi yumye byitwa primaire primaire, kongeramo bibiri cyangwa byinshi byongeweho byitwa guhinduka kabiri. Ubwiza bwa poro yumye biterwa no guhitamo neza ibice no guhuza no guhuza ibice bitandukanye. Kuberako inyongeramusaruro yimiti ihenze cyane, kandi igira ingaruka zikomeye kumikorere ya poro yumye. Kubwibyo, mugihe uhitamo inyongeramusaruro, ingano yinyongera igomba guhabwa umwanya wambere. Ibikurikira nintangiriro ngufi kuburyo bwo gutoranya imiti yongera selile selile.
Cellulose ether nayo yitwa rheology modifier, imvange ikoreshwa muguhindura imiterere ya rheologiya ya minisiteri ivanze vuba, kandi ikoreshwa mubwoko bwa minisiteri. Imiterere ikurikira igomba kwitabwaho muguhitamo ubwoko bwayo na dosiye:
(1) Kubika amazi ku bushyuhe butandukanye;
(2) Ingaruka yibyibushye, ubukonje;
(3) Isano iri hagati yubushyuhe nubushyuhe, ningaruka zo guhora imbere ya electrolyte;
(4) Imiterere n'urwego rwa etherification;
.
(6) Umuvuduko wo gusenyuka, imiterere nuburyo bwuzuye bwo guseswa.
Usibye kongeramo ether ya selile (nka methyl selulose ether) kuri pompe yumye, aside polyvinyl vinyl ester irashobora kandi kongerwamo, ni ukuvuga guhindura kabiri. Imashini idahwitse (sima, gypsumu) muri minisiteri irashobora kwemeza imbaraga zo gukomeretsa cyane, ariko ntigire ingaruka nke kumbaraga zingutu n'imbaraga zoroshye. Polyvinyl acetate yubaka firime ya elastike mu byobo by'amabuye ya sima, bigatuma minisiteri ishobora kwihanganira imitwaro myinshi kandi igahindura imyambarire. Imyitozo yerekanye ko kongeramo urugero rutandukanye rwa methyl selulose ether na acide polyvinyl acide vinyl ester kumata yumye yumye bishobora gutegura minisiteri yoroheje yo gusiga isahani ihuza minisiteri, guhomesha minisiteri, gushushanya amarangi, hamwe na minisiteri yububiko bwa beto ya moteri hamwe na minisiteri yo kwisuzumisha kuri gusuka amagorofa, nibindi. Kuvanga byombi ntibishobora kuzamura ubwiza bwa minisiteri gusa, ahubwo binanoza cyane ubwubatsi.
Mubikorwa bifatika, kugirango tunoze imikorere rusange, birakenewe gukoresha inyongeramusaruro nyinshi mukomatanya. Hariho igipimo cyiza cyo guhuza mubyongeweho. Igihe cyose igipimo cya dosiye nigipimo gikwiye, birashobora kunoza imikorere ya minisiteri uhereye kubintu bitandukanye. Nyamara, iyo ikoreshejwe wenyine, ingaruka zo guhindura kuri minisiteri iba mike, ndetse rimwe na rimwe ndetse ningaruka mbi, nko kongeramo selile yonyine, mugihe wongeyeho ubumwe bwa minisiteri no kugabanya urugero rwa delamination, byongera cyane gukoresha amazi ya minisiteri kandi gumana imbere muri slurry, biganisha ku kugabanuka gukomeye kwingufu zo kwikuramo; Iyo bivanze nibintu byinjira mu kirere, nubwo urugero rwa stratifike ya minisiteri rushobora kugabanuka cyane, kandi n’amazi nayo akagabanuka cyane, ariko imbaraga zo kwikuramo za minisiteri zizagabanuka bitewe n’imyuka myinshi. Kugirango tunoze imikorere ya minisiteri yububoshyi ku rugero runini, kandi icyarimwe wirinde kugirira nabi indi mitungo ya minisiteri, ubudahwema, imiterere n'imbaraga za minisiteri yububiko bigomba kuba byujuje ibisabwa n'umushinga hamwe na tekiniki bijyanye. Ibisobanuro. Muri icyo gihe, nta paste ya lime ikoreshwa, kuzigama Kuri sima, kurengera ibidukikije, nibindi, birakenewe ko hafatwa ingamba zuzuye, guteza imbere no gukoresha ibivangavanze biva muburyo bwo kugabanya amazi, kwiyongera kwijimye, kubika amazi no kubyimba, kandi guhumeka ikirere.
