Methylcellulose (MC) ni inkomoko yabonetse muri selile binyuze mu kuvura methylation kandi ifite imiterere yihariye yumubiri na chimique. Nka nyongeramusaruro ikoreshwa cyane, igira uruhare runini mubikorwa bitandukanye byinganda, harimo ibikoresho byubaka, ibiryo, ubuvuzi, kwisiga no gutwikira, nibindi. ikintu cyingenzi mugutezimbere no kuzamura inganda.
1. Ingaruka mbi
Umubyimba wa methylcellulose uba inyongeramusaruro munganda zubaka no gutwikira. Mu nganda zubaka, cyane cyane muri sima ishingiye kuri sima na gypsumu, methylcellulose irashobora kongera cyane ubudahangarwa nubwiza bwa formula, bityo bikazamura imikorere yibikoresho. Kubitwikiriye no gusiga amarangi, kongeramo methylcellulose birashobora kubuza neza amazi gutemba cyane kandi bikongerera guhuza hamwe nuburinganire.
Uburyo bwo kubyimba ahanini binyuze muburyo bwo gushiraho imiyoboro y'urusobe mu gisubizo na methylcellulose. Iminyururu ya molekile ya methylcellulose ikorana binyuze mumigozi ya hydrogène mumazi kugirango ibe igisubizo hamwe nubwiza runaka. Uru rusobe rushobora gufata no gukosora molekile zamazi, bityo bikongerera ubwiza nuburinganire bwa sisitemu y'amazi.
Kubika amazi
Mubikoresho byubwubatsi nka sima ya sima na gypsum slurries, ibintu byo gufata amazi ya methylcellulose nibyingenzi. Ibikoresho byo kubaka bisaba ubwinshi bwamazi kugirango ugire uruhare mugihe cyo gukira. Gutakaza amazi imburagihe bizatera gukira bidahagije ibikoresho, kugabanuka kwingufu, cyangwa gucika hejuru. Methylcellulose ikora firime yoroheje hejuru yibikoresho kugirango irinde guhumeka cyane kwamazi kandi urebe ko sima, plaster nibindi bikoresho bifite ubushuhe buhagije mugihe cyo gukira, bityo bikongerera imbaraga nigihe kirekire.
Izi ngaruka zo gufata amazi ni ingenzi cyane cyane ahantu humye cyangwa ubushyuhe bwo hejuru, bituma methylcellulose ihindura imikorere yimikorere yinganda mubihe bidukikije bikabije.
3. Guhuza no kongera imbaraga zumubiri
Imiterere ya methylcellulose nayo ni nziza mubikorwa byinganda. Kurugero, mumatafari yubundi bwoko nubundi buryo bwo guhuza ibintu, methylcellulose irashobora kunoza imiterere yimikorere, bigatuma ibikoresho bihuza bikomera neza kumurimo. Imiterere miremire ya methylcellulose irashobora gukorana nibikoresho bya matrix kugirango byongere imbaraga zihuza, bityo bitezimbere muri rusange imbaraga zububiko.
Muri plastiki ikomezwa na fibre (FRP), methylcellulose irashobora kongera imbaraga nubukomezi bwibikoresho bikomatanyije binyuze mumiterere ya fibrous, bigaha ibikoresho imbaraga zikomeye kandi bikarwanya imbaraga, bityo bikazamura igihe kirekire mubikorwa byinganda. igitsina.
4. Gushiraho firime
Methylcellulose ifite ubushobozi bwiza bwo gukora firime mugukemura, kandi uyu mutungo wakoreshejwe cyane mubikorwa byinshi byinganda. Mu nganda zo gutwika no gusiga amarangi, methylcellulose irashobora gukora firime imwe yo gukingira yongerera amazi amazi hamwe n’imiti irwanya imiti.
Mu nganda zibiribwa, methylcellulose nayo ikoreshwa muburyo bwo gutwikira cyangwa gukora firime, cyane cyane mububiko bushya bwo kubika imbuto, imboga nibindi biribwa. Mugukora firime yoroheje, methylcellulose itinda gutakaza ubushuhe kandi ikarinda ibiryo ibidukikije.
5. Gutuza no kwigana
Methylcellulose irashobora gutanga igisubizo cyinshi-cyinshi iyo gishongeshejwe mumazi, gifite ingaruka zihamye kandi zitera imbaraga. Uyu mutungo ni ingenzi cyane mu nganda nko gutwika, gusiga amarangi, kwisiga no gutegura imiti. Mu gusiga amarangi, methylcellulose irashobora guhagarika ikwirakwizwa rya pigment, ikarinda gutura, kandi igateza imbere uburinganire nuburinganire bwacyo; muburyo bwo kwisiga, methylcellulose ikora nka emulisiferi kugirango ihagarike sisitemu ivanze namazi no gukumira Stratification ibaho.
Mu myiteguro ya farumasi, methylcellulose ikunze gukoreshwa mu kubyimba no guhagarika imyiteguro y’amazi yo mu kanwa kandi itwara ibiyobyabwenge. Ubwiza bwacyo hamwe nubushakashatsi bwa firime birashobora gufasha ibiyobyabwenge kurekurwa gahoro gahoro, kongera igihe cyibiyobyabwenge, no kunoza bioavailable yibiyobyabwenge.
6. Ibikoresho byo gutwika ubushyuhe
Umutungo wingenzi wa methylcellulose nigikorwa cyihariye cyogukoresha ubushyuhe bwumuriro, aho gihinduka gel iyo gishyushye. Ibiranga bituma bidasimburwa mubikorwa bimwe bidasanzwe byinganda. Kurugero, mubucuruzi bwibiribwa, methylcellulose ikoreshwa mugutunganya ibiryo birimo amavuta make. Gele ikozwe nyuma yo gushyushya ifite uburyohe busa nibinure, bigatuma ibiryo birimo amavuta make bigumana uburyohe nuburyo bwiza. Mu nganda zubwubatsi, uyu mutungo wa gelling wumuriro utezimbere kuramba no gutuza mubikoresho byubwubatsi mubushyuhe bwo hejuru.
7. Biocompatibilité no kubungabunga ibidukikije
Methylcellulose, nkibisanzwe biva mubisanzwe, bifite biocompatibilité nziza hamwe n’ibidukikije. Ibi bituma irushaho gukundwa mubikorwa byinganda bigezweho, cyane cyane mubice bisabwa cyane kurengera ibidukikije, nkinyubako zicyatsi, ibinyabuzima byangiza ibidukikije nibikoresho bipakira byangirika. Methylcellulose irashobora kwangirika bisanzwe, kugabanya umutwaro wibidukikije no guhuza ninganda ziterambere ryiterambere rirambye.
8. Kunoza imikorere yo gutunganya
Mu musaruro w’inganda, methylcellulose irashobora kunoza imikorere. Kurugero, mubikoresho byubwubatsi, methylcellulose irashobora kongera umuvuduko no gufata amazi yibikoresho, bityo bikazamura ubworoherane nubwubatsi; mu kwisiga no gutegura imiti, methylcellulose irashobora kunoza imiterere ya formula no kugabanya imvura. no gusibanganya, bityo ukongerera igihe cyibicuruzwa. Iyi mitungo ituma methylcellulose itezimbere cyane umusaruro mugihe uhindura inganda.
Nka nyongeramusaruro myinshi, methylcellulose ikoreshwa munganda nyinshi nkubwubatsi, ibiryo, ubuvuzi, kwisiga, gutwikira, nibindi bitewe nubwinshi bwayo nko kubyimba, kubika amazi, guhuza, gukora firime, gutuza, emulisation hamwe na gelling yumuriro. igira uruhare runini murwego. Ntishobora gusa kongera imiterere yumubiri yinganda, ahubwo inatezimbere umusaruro kandi ikenera inganda zitandukanye. Muri icyo gihe, ibinyabuzima no kubungabunga ibidukikije bya methylcellulose nabyo bigira ibikoresho byiza byujuje ibisabwa byiterambere rirambye. Mugukoresha mu buryo bushyize mu gaciro methylcellulose mubikorwa byinganda, ntibishobora kuzamura ubwiza bwibicuruzwa gusa, ahubwo binateza imbere iterambere niterambere ryikoranabuhanga ryinganda.
