Ububiko bwa Cellulose (nka HPMC, HYDROXYPropyl methylcellse) na MHEC (methyl hydroxyithyyl selile Bagira uruhare runini mugutezimbere imbaraga za minisiteri, kunoza imikorere yubwubatsi no kwagura igihe cyimisozi.
1. Imiterere y'ibanze ya HPMC na MHEC
HPMC ni compound ya polymer yabonetse kubishushanyo mbonera bya selile karemano. Molekile yayo irimo amatsinda ya hydroxyle na methyl, ituma ifite amazi meza, kubyimba no gutuza. MHEC isa na HPMC, ariko ifite amatsinda menshi ya hydroxyeryethyty mumiterere yacyo, bityo amazi yo kwikebana no guturika kwa MHEC atandukanye. Bombi barashobora gushiraho imiterere yumuyoboro muri minisiteri kandi bazamura imitungo yumubiri ya minisiteri.
2. Uburyo bwibikorwa bya selile ether muri minisiteri
Nyuma yo kongeraho HPMC cyangwa MHEC kuri minisiteri, ether ether molecules ikora sisitemu ihamye yakozwe binyuze mumazi, ibindi bice bigize imiti. Sisitemu irashobora kunoza cyane imitungo ya minisiteri.
Ingaruka zijimye: HPMC na MHEC barashobora kongera ubudabubasha bwa minisiteri, byoroshye gukora mugihe cyo kubaka. Iyi ngaruka mbi kandi ifasha kugabanya amazi ya sima Paste, kunoza amahano ya minisiteri, bityo akazamura imbaraga za minisiteri.
Ingaruka yo kugumana amazi: Imiterere ya HPMC na MHEC irimo amatsinda ya hydrophilic, ashobora kurengana buhoro, bityo ukinga umwanya wa minisiteri kandi wirinde gucikamo amazi cyangwa ubukene bukabije kubera guhina amazi byihuse.
Gutezimbere amazi hamwe nubwubatsi: ether ether ifasha kunoza amazi ya minisiteri, bigatuma bigenwa neza hejuru yishingiro, bifasha kugabana kimwe cyo kugabana imbaraga zubuhinzi.
3. Ingaruka za selile ether ku mbaraga za mirtar
Ongeraho selile ether kuri minisiteri mubisanzwe bigira ingaruka kuburyo butaziguye imbaraga za minisiteri. By'umwihariko, ingaruka za HPMC na MHEC ku mbaraga za mirtar zihindagurika zigaragarira mu ngingo zikurikira:
3.1 Ingaruka ku mbaraga zambere zimbaza za minisiteri
HPMC na MHEC barashobora kunoza imikorere ifatanye hagati ya minisiteri. Iyo iyubakwa irangiye, imbaraga zo guhuriza hamwe hagati yubutaka kandi umutwe uraterana cyane kuko ether ya selile irashobora kugumana amazi no kugabanya gukama imburagihe cya sima. Ibi ni ukubera ko sima yamahoro murashobora gukomeza neza, itera imbere igeragezwa rya minisiteri.
3.2 Ingaruka ku mbaraga z'igihe kirekire za minisiteri
Uko ibihe bigenda bisimburana, ibice bya cement bigize gahunda ikomeza, kandi imbaraga za burundu zizakomeza kwiyongera. Imikorere yo kugumana amazi ether iracyafite uruhare runini muriki gikorwa, yirinde gukoraho amazi muri minisiteri, bityo bigabanya imbaraga ziterwa namazi adahagije.
3.3 Kunoza imitako ya minisiteri
HPMC na MHEC barashobora kandi kuzamura indwara ya minisiteri. Uburyo bwacyo bwo gukora ahanini kugirango butezimbere imiterere yimbere ya minisiteri kandi itinda igipimo cyuzuye cyamazi hejuru ya minisiteri, bityo bikagabanya ikibazo cyacitse byatewe no guhumeka amazi yihuta. Byongeye kandi, imiterere ya colloidal yakozwe na selile ether muri minisiteri irashobora kunoza ubukana rusange bwa minisiteri, bikaba bidashoboka ko bicika mugihe bakorewe imbaraga zo hanze.
3.4 Ingaruka ku mbaraga zo kunoza minisiteri
Ubushakashatsi bwerekanye ko yongeramo amafaranga akwiye ya HPMC cyangwa MHEC birashobora kunoza imbaraga za minisiteri nta buryo bugoye cyane uburemere bwa minisiteri. Mubisanzwe, dosiye nziza ya selile ether ni 0.5% -1.5%. Inyongera rikabije rirashobora gutera minisiteri kugira amazi arenze, nayo igira ingaruka kumiterere yacyo. Kubwibyo, umubare wuzuye wa selile yongeyeho ningirakamaro kugirango ateze imbaraga za minisiteri.
4. Kugereranya ubwoko butandukanye bwa bahanga muri selire
Nubwo HPMC na MHEC bisa muburyo bwabo bwibikorwa, ingaruka zabo ku mbaraga zibangamira minisiteri ziratandukanye muburyo bufatika. MHEC ni hydrophilic kuruta HPMC, kuburyo muburyo buhebuje, MHEC irashobora kugira ingaruka zikomeye mukuzamura imbaraga. HPMC, kurundi ruhande, irahamye ubushyuhe busanzwe nubushuhe, kandi ikwiranye cyane cyane niterambere rya minisiteri gakondo.
Abahanga muri Celefoni (HPMC na MHEC) bakunze gukoreshwa inyongeramusaruro ku misozi, kunoza imbaraga za minite, bafunzwe cyane na minisiteri binyuze mu kubyimba, kugumana amazi, no kunoza amazi y'amazi. Gukoresha neza Uburenganzira bwa Cellulose ntibishobora kuzamura gusa amarangamutima hagati ya minisiteri no gusimburana, ahubwo anatezimbere kurwanya minisiteri, kandi akagura ubuzima bwa minisiteri. Ubwoko butandukanye bwa selile bafite ubushobozi butandukanye, no guhitamo ibicuruzwa nuburyo bukwiye ni ngombwa kugirango utezimbere imikorere ya mirtar.
