Mune yakaoma yakaoma, cellulose ether inonyanya kuwedzerwa iyo inogona kuvandudza zvakanyanya kuita kwekunyorova kwemutema uye kukanganisa kuita kwekuvaka kwemotokari. Methyl Cellulose ether inoda basa rekuchengeta mvura, kurerutsa, uye kuvandudzwa kwekuita kwekuvaka. Yakanaka mvura yekuchengetedza inovimbisa kuti motsi haizo kukonzera sanding, poda uye kuderedza simba nekuda kwekushomeka kwemvura uye isina kukwana yeComent hydration; Kuwedzera simba simba rekuumbwa kweiyo methyl inowedzera kwazvo, uye kuwedzera methyl Celler cell Mukuwedzera, basa rakasiyana nemheremello muzvigadzirwa zvakare zvakasiyana, semuenzaniso: Cellulose mumakakomberedzwa zvinoshongedzwa zvinogona kuwedzera nguva yekuvhura uye kugadzirisa nguva; cellulose mukusvava kwemauto anogona kuvandudza simba rerudzi remagetsi akanyorova; Mukuzvimirira, cellulose inotora chikamu mukudzivirira kugadzirisa, kusarongeka uye kuoma.
Kugadzirwa kweCellulose ether kunonyanya kugadzirwa mafambiro echisikigo kuburikidza neAlkali kupaza, kugadzira maitiro (ekushongedza), kugeza, kuomesa uye mamwe maitiro. Midziyo mikuru yemidziyo yemasango inogona kukamurwa mu: Cotton fiber, cedar fiber, beech fiber, etc. yavo degree yePolymerization yakasiyana, iyo ichakanganisa visikoka yekupedzisira yezvigadzirwa zvavo. Parizvino, major Cellulose Vagadziri vanoshandisa machira ekotoni (a-chigadzirwa che nitrocellose) seyakakura zvinhu zvekushandisa. Cellulose etana inogona kukamurwa kuita ionic uye isiri-ionic. Iyo Ionic mhando inonyanya kusanganisira Carboxymelm Cellbolose munyu, uye iyo is-ionic mhando inonyanya kusanganisira methyl Cellerethyl (methyl hydroxoseeth (proyl) cellulose, uye hydroxethyl cellulose. Su uye zvichingodaro. Mune yakaoma Powder Darare, nekuti Ionic Celleryl Cellemose Sky (haawanzo kushandiswa muzvivakwa zvePowder yakadai seyakagadziriswa lime seyakagadzirwa zvinhu.
Kuchengetwa kwemvura kwemasero zvakare kunoenderana ne tembiricha inoshandiswa. Kuchengeta kwemvura kweMethyl Cellulose theri kuderera nekuwedzera kwekushisa. Semuenzaniso, muzhizha, kana paine mwenje wezuva, iyo rusvingo rwekunze putty yakaiswa, iyo inowanzo atsa kurapa kwesimendi nemutya. Kuomerwa uye kuderera kwehuwandu hwekuchengetwa kwemvura kunotungamira kumanzwiro ari pachena kuti zvese zvinoitwa pakuvaka uye kuita kwekurwisa-kupaza kwakakanganiswa. Mune ino kesi, inonyanya kutsoropodza kuderedza pesvedzero yezvinhu zvekushisa. Dzimwe nguva hazvigone kusangana nezvinodiwa zvekushandisa. Mamwe marapirwo anoitwa pamaseru, akadai sekuwedzera mwero wekutsva, nezvimwewo, kuitira kuti mvura idzo dzive nemhedzisiro inogona kuramba ichirarama zviri nani pakupisa kwakanyanya.
Kuchengeta kwemvura kweCellulose: Zvinhu zvakakosha zvinokanganisa kuchengetwa kwemvura kwerufu zvinosanganisira huwandu hweCellulose zvakawedzerwa, iyo viscosity yemasero, iyo meso emherekuru, uye tembiricha yenzvimbo yekushandisa.
Viscosity of cellulose: Kazhinji, iyo yepamusoro yekuvimbika, iyo yakakwira iyo visikopo, iyo yakakwira iyo smeular huremu hwemasero, uye kuderera kunoenderana mukuita kwayo kwekushanda uye kusimba kwekuvaka uye kusimba kwemutya. Yakakwira iyo viscosity, zvakanyatsojeka zvinokanganisa mudhaka, asi haina hukama zvakananga. Iyo yepamusoro viscosity, iyo yakawanda viscous iyo dari yakanyorova ichave. Munguva yekuvakwa, ichanamatira kune iyo scraper uye ine yakanyanya kuomerera kune iyo substrate, asi haizobatsire zvakawanda kuwedzera simba rekusimba kwerufu, uye kuita kwekunyepedzera hakuzove pachena panguva yekuvaka.
Iyo yakajeka ye cellulose: Iyo yakanaka inokanganisa iyo solubility yemheremalose ether. Coarse cellalose inowanzo granular uye inopararira zviri nyore mumvura pasina anounganidzwa, asi iyo yekunyoroveswa inononoka. Izvo hazvina kukodzera kushandiswa mune yakaoma powder muhari. Zvipomeri mimwe mheremello celluclose, hazvisi nyore kuparadzira nekunyungudika mumvura, uye zviri nyore kuti uwedzere. Chete chete yakakwana poda inogona kudzivisa methyl cellulose ether agglomeration kana uchiwedzera mvura uye kumutsa. Asi iyo mheremhese cellulose ether haisati yapambadza asi zvakare inoderedza simba romunharaunda renzvimbo. Kana doro rakaoma kudaro roda rakavakwa munzvimbo yakakura, kurapa kwekumhanyisa kwerudzi rwemunharaunda zviri pachena kuderedzwa, uye marara nekuda kwenguva dzakasiyana dzekuporesa dzinoonekwa. Nekuda kwenguva pfupi yekusanganisa nguva, dhudzi nekuvaka michina kunoda mukurumbira wepamusoro.
