Selile ether muri tile

1 IRIBURIRO

Sima ishingiye ku buryo bushingiye kuri sile ifata minisiteri idasanzwe ya minisiteri ivanze yumye, zigizwe na sima nkuru imvange. Mubisanzwe, bigomba gusa kuvangwa namazi mugihe ukoreshejwe. Ugereranije na pertable isanzwe, irashobora kunoza imbaraga zingana hagati yibikoresho hamwe na sustrate, kandi bifite isura nziza kandi ifite amazi meza namazi meza. Irakoreshwa cyane kugirango yambure ibikoresho byo gushushanya nko kubaka amabati yimbere kandi yo hanze, amabati, nibindi birakoreshwa cyane muburi bwimbere kandi bwinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa yinyuma, amagorofa, amagorofa, ibikoni nibindi biterana ahantu h'imitako. Kugeza ubu nicyo cyakoreshejwe cyane cyane ibikoresho.

Mubisanzwe iyo duciriye urubanza imikorere yubukorikori, ntitwitaye gusa kumikorere yacyo nubushobozi bwo kurwanya, ariko kandi bwitondera imbaraga zacyo no gufungura igihe. Cellulose Ether muri Tile akigira ingaruka gusa kumiterere yuburyo bwamajipo, nko gukora neza, guhirika icyuma, nibindi, ariko nanone bifite ingaruka zikomeye kumiterere ya mashini

2. Ingaruka mugihe cyo gufungura cyo gutwikira

Iyo ifu ya rubber na selile ether co-minisiteri itose, uburyo bwamakuru amwe bwerekana ko ingufu za rubber zifite imbaraga za kinetic, kandi ether ya selile ibaho mu mazi yinyamanswa kandi igira ibihe. Impagarara zo hejuru ya selile zirarenze iy'ifu ya rubber, kandi na selile ya ether ether ikungahaza imigaragarire ya mirtar izagirira akamaro ko ishingwa rya hydrogen hagati yifatizo hamwe na selile.

Mu mirima itose, amazi yo muri minisiteri arahumeka, kandi ether ya selile irakungahaza hejuru, kandi izaba ishyirwa hejuru ya minisiteri muminota 5, izagabanya umubare wakurikiyeho, nkuko amazi menshi ari Yakuwe mu gice cya minisiteri yimuka ku kimenyetso cyoroheje, kandi filime yakozwe mu ntangiriro irashonga igice, kandi kwimuka kw'amazi bizazana selile ya selile ikungahaza hejuru ya minisiteri.

Kubwibyo, gushiraho filime ya selile ether hejuru ya minisiteri igira uruhare runini mumikorere ya minisiteri. 1) Filime yashyizweho ni inanutse kandi izashonga kabiri, idashobora kugabanya guhumeka no kugabanya imbaraga. 2) Filime yashizweho ni ndende cyane, kwibanda kuri selile ether mumazi yamazi ya minisiteri ni menshi, kandi virusi ni ndende, ntabwo byoroshye gucamo firime yubuso mugihe amabati. Birashobora kugaragara ko imitungo yo gukora film ya selile ether ifite ingaruka zikomeye mugihe cyo gufungura. Ubwoko bwa selile (HPMC, HPMC, MC, nibindi) hamwe nurwego rworoshye (impamyabumenyi) bigira ingaruka kumiterere ya selile ya selile, nubukomere bwa firime.

3. Ingaruka ku mbaraga zo gushushanya

Usibye gutanga imitungo ifatika yavuzwe haruguru kuri minisiteri, ether ether kandi itinda hydration kinetics ya sima. Ingaruka zidindiza cyane biterwa ahanini na adsorpription ya selile etherkiles ku byiciro bitandukanye muri siteli, ariko muri rusange, muri rusange, muri rusange, muri kadamu na Calcium hydroxide. Ku bicuruzwa bya shimi, ntibikunze kwishyurwa ku cyiciro cya mbere cya clinker. Byongeye kandi, ether ether igabanya kugenda kwa ion (ca2 +, bityo rero

Ibyatsi ni ikindi gipimo cyingenzi, kigereranya ibiranga imiti ya selile. Nkuko byavuzwe haruguru, viscozetity igira ingaruka ahanini ku bushobozi bwo kugumana amazi kandi kandi igira ingaruka zikomeye ku gikorwa cya minisiteri nshya. Icyakora, ubushakashatsi bwageragejwe bwasanze ubukuru bwa selile ether nta ngaruka bufite muri sima hydration hydration mometics. Uburemere bwa molekile bufite ingaruka nke kuri hydration, kandi itandukaniro rinini hagati yuburemere butandukanye bwa molekile ni 10min. Kubwibyo, uburemere bwa molekiri ntabwo aribwo buryo bwingenzi bwo kugenzura smant hydration.

Ubucuruzi bwa selile yaka biterwa n'imiterere yacyo, kandi inzira rusange yanzuye ivuga ko, kuri Mhec urwego rwo hejuru, ingaruka nke cyane za selile. Byongeye kandi, ingaruka zidindiza zisimbuye hydrophilique (nko gusimbuza HEC) irakomeye kurenza iy'isi (nko gusimburwa na MH, MHPS, MHPC). Ingaruka zidindiza za selile ziragira ingaruka cyane cyane ibipimo bibiri, ubwoko nubunini bwitsinda risimbutse.

Ubushakashatsi bwacu bwacu bwanasanze ibikubiye mu basimbuye bigira uruhare runini mu mbaraga zubukanishi. Twasuzumye imikorere ya HPMC dufite impamyabumenyi zitandukanye zo gusimburwa muri Tile kumeneka, kandi tugerageza ingaruka za elegike zirimo amatsinda atandukanye ku ngaruka ku ngaruka ku mitungo yakanishi.

Mu kizamini, dusuzuma HPMC, nikintu cya ethend, bityo tugomba gushyira hamwe amashusho yombi. Kuri HPMC, ikeneye urwego runaka rwo kwinjiza kugirango amazi akemure kandi akemuke. Tuzi ibikubiye mu gusimburwa nabyo bigena ubushyuhe bwa Gel bwa HPMC, bugena kandi gukoresha ibidukikije bya HPMC. Muri ubu buryo, itsinda ryibanze rya HPMC risanzwe rikoreshwa naryo ryakozwe murwego. Muri uru rwego, uburyo bwo guhuza uburyo na hydroxypropoxy kugirango tugere ku ngaruka nziza nibiri mubushakashatsi bwacu. Igishushanyo 2 cyerekana ko murwego runaka, kwiyongera kubikubiye mu matsinda bizaganisha ku buryo bwo kumanuka mu mbaraga zikurura, mu gihe kwiyongera kw'ibikubiye mu matsinda ya hydroxyle . Hariho ingaruka nkizo zo gufungura amasaha.

Guhindura inzira yubufatanye bwa mashini munsi yigihe cyuzuye kijyanye nibyo munsi yubushyuhe busanzwe. HPMC ifite uburyo bwimbitse (DS) ibirimo na hydroxyproxyl (ms) birimo gukomera kwa firime, ariko bizagira ingaruka kuri minisiteri itose uko binyuranye. imitungo itose.
