Kwishyira hamwe-ibice (SLC) ni byumye-byumye kandi bihindagurika ibikoresho byo hasi bigenda byamamara cyane kubera uburebure budasanzwe n'ubuso bworoshye.Zikoreshwa cyane mubikorwa byo guturamo nubucuruzi kugirango binganize hejuru ya beto mbere yo gushyira itapi, vinyl, ibiti cyangwa amagorofa.Nyamara, imikorere ya SLCs irashobora guterwa nibintu bitandukanye bidukikije nkubushyuhe, ubushuhe, hamwe na substrate adhesion.Kugirango uzamure imikorere yikomatanya-urwego, abayikora batangiye kongeramo hydroxypropylmethylcellulose (HPMC) na hydroxyethylmethylcellulose (HEMC) nkibibyimbye.
HPMC ni polymer yamazi ashonga ikora gel ihamye iyo ikwirakwijwe mumazi.Bikunze gukoreshwa mubikorwa byububiko bitewe nuburyo bwiza bwo kubika amazi hamwe nibintu bifatika.Iyo wongeyeho kwishyira hamwe, HPMC itezimbere urujya n'uruza rw'imvange.Igabanya kandi amazi akenewe kugirango ugere kubyo wifuza, birinda kugabanuka no guturika mugihe cyo gukira.Byongeye kandi, HPMC irashobora kongera imbaraga zifatika za SLC, bityo igahindura imyambarire yayo.
HEMC nubundi buryo bwo gushonga amazi polymer bukoreshwa cyane mubikorwa byubwubatsi nkumukozi wibyimbye na rheologiya.Irashobora kunonosora, guhuza hamwe no guhuza ibikoresho byubwubatsi, bigatuma iba inyongera ikunzwe muri SLC.Iyo wongeyeho muri SLC, HEMC yongerera ubwiza bwuruvange, ikemerera gukwirakwira cyane kandi ikomera neza kuri substrate.Itezimbere kandi imiterere-yimiterere yikomatanya, igabanya amahirwe yo kutagira ubuso nka pinholes hamwe nu mwuka mwinshi.Mubyongeyeho, HEMC yongerera imbaraga muri rusange imbaraga za SLC, bigatuma iramba kandi ntishobora kwangirika.
Imwe mu nyungu zingenzi zo gukoresha HPMC na HEMC murwego rwo kwishyira hamwe ni uko batezimbere imikorere yuruvange.Ibi bivuze ko abashoramari bashobora gusuka no gukwirakwiza SLC byoroshye, bikagabanya akazi gakenewe kumurimo.Kandi, kongeramo HPMC na HEMC muri SLC bifasha kugabanya igihe cyo gukama kivanze.Ni ukubera ko babuza amazi muruvange guhumeka, bikavamo inzira irenze kandi ihamye yo gukira.
Iyindi nyungu yo gukoresha HPMC na HEMC murwego rwo kwishyira hamwe ni uko bazamura ubwiza rusange muri etage yarangiye.Iyo wongeyeho kuvanga, izi polymers zongera guhuza SLC kuri substrate, bikagabanya amahirwe yo gutsindwa.Ibi byemeza ko ijambo rizaramba kandi rikagumaho neza no mumodoka iremereye.Byongeye kandi, gukoresha HPMC na HEMC birema ubuso bworoshye, buringaniza byoroshye gushyira ibindi bikoresho byo hasi hejuru.
Kubijyanye nigiciro, kongeramo HPMC na HEMC murwego rwo kwishyiriraho ibiciro birahendutse.Iyi polymers iraboneka byoroshye kumasoko kandi irashobora kwinjizwa muburyo bworoshye bwa SLC mugihe cyo gukora.Mubisanzwe, umubare muto gusa wa HPMC na HEMC urakenewe kugirango ugere kumurongo hamwe nibikorwa bisabwa kuri SLC, ifasha kugumya ibiciro byumusaruro muke.
Icya nyuma ariko ntabwo ari gito, ikoreshwa rya HPMC na HEMC murwego rwo kwishyira hamwe ni igisubizo cyangiza ibidukikije.Izi polymers zirashobora kwangirika kandi ntizirimo ibintu byangiza, bivuze ko nta ngaruka zibangamira ubuzima bwabantu cyangwa ibidukikije.Imikoreshereze yabo muri SLC ifasha guteza imbere iterambere rirambye mubikorwa byubwubatsi, ikintu cyingenzi mubitekerezo byisi.
Ongeraho HPMC na HEMC murwego rwo kwishyiriraho ibice bifite ibyiza byinshi, bituma biba igisubizo cyiza kubasezeranye nababikora.Izi polymers zitezimbere uburyo bwo kuvanga, kugabanya igihe cyo kumisha, kuzamura ubwiza bwubutaka bwuzuye, kugumya ibiciro byumusaruro muke no guteza imbere kuramba.Mugihe inganda zubwubatsi zikomeje gushakisha ibisubizo bishya kugirango tunoze imikorere, ireme kandi rirambye ryibicuruzwa byayo, birashoboka ko tuzabona gukoresha HPMC na HEMC muri SLC mugihe kiri imbere.
