Ikhoza hydroxypropyl methyl cellulose akumanga guluu

Mulingo womanga guluu ndi vuto kwa makasitomala. Choyamba, kuchuluka kwa gululo kuyenera kuganizira zinthu zosaphika. Chifukwa chachikulu chopangira zigawo zomatira ndi kusagwirizana pakati pa acrylic emulsion ndi hydroxypropyl no meth methylcellulose (hpmc). Chachiwiri, chifukwa cha nthawi yosakanikirana; Palinso malo owoneka bwino opangira guluu. Pomanga guluu, ndikofunikira kugwiritsa ntchito khofi wa nthawi yomweyo hydroxpyll methylcellulose (hpmc), chifukwa HPMC imangomwazika m'madzi, sizingasungunuka. Patatha pafupifupi mphindi ziwiri, mawike amadzimadzi amawonjezeka pang'onopang'ono, ndikupanga yankho lowoneka bwino la colloidal. Malo otentha osungunuka, akumakumana ndi kuzizira, amatha kusulitsidwa mwachangu m'madzi otentha, m'madzi otentha adachepera. Kutentha kwatsikira mpaka kutentha kwinakwake, kubwereza kwa ma vickotion kumachitika mpaka yankho lowoneka bwino la colloidal limapangidwa. Kumanga Buy Hydroxpyl Meth Celyose (HPMC) kugwiritsidwa ntchito kwambiri kwa 2-4 kg.

Hydroxypropyl me cellulose (hpmc) mu gululo lomanga munthawi yokhazikika, sangakhalepo bwino posintha ndi 200,000 S cefc. Ma IscCon'ness ndi omwe ali ophatikizika ndi mphamvu zomatira. Maonekedwe a mafakiti, m'munsi mwamphamvu. General akuwoneka 100,000 s ndi yoyenera.

Tsopano zokongoletsera, hydroxypropyl methyl cellulose ntchito ndizokhazikika.

Kodi kuchuluka kumeneku kungayesedwe bwanji? Kukutengerani:

Nthawi yomweyo sakanizani cmc ndi madzi kuti mupange matope osungira matope. Mukakhazikitsa cmc phala, madzi ozizira amawonjezeredwa mumphika wokutira ndi makina osangalatsa. Makina osangalatsa atayamba, carboxymethyl cellulose pang'onopang'ono kwambiri mwachangu mu thanki, ndikusakaniza, ndikupanga madzi boxymethyl cellose bwino. Mukatha kulowa mu komiti yoyang'anira, nthawi zambiri ndikofunikira kuti muthe kufalitsa komanso kusakanikirana, kuti muchepetse makomidwe ndi mapangidwe a komiti yoyang'anira "ndikusintha kuchuluka kwa komiti yoyang'anira.

Nthawi yosakanikirana ndiyosiyana ndi nthawi ya masentimita kuti isungunuke kwathunthu. Ndi matanthauzidwe awiri. Nthawi zambiri, nthawi yosakanikirana ndi yofupikira kwambiri kuposa nthawi yoti masentimita asungunuke kwathunthu, kutengera tsatanetsatane. Kutsimikiza kwa nthawi yosakanikirana ndi kutengera kusakanikirana pomwe masentimita amabalalika m'madzi popanda ma cmcs, kulola masentimita ndi madzi kuti adzilowe muyezo wa data. Kuthetsa nthawi yofunikira kwa CMC kuti musungunuke kwathunthu pazifukwa zingapo:

(1) CMC ndi madzi zimasuliridwa kwathunthu, ndipo palibe zida zolekanitsa zamadzimadzi pakati;

.

(3) Pambuyo posakaniza, phala lilibe utoto ndipo limawonekeratu, ndipo palibe nkhani ya tinthu. Kuchokera ku CMC Thumba Zosakaniza ndi thanki ndi kusakaniza kwamadzi kuti mudzathe kuwonongeka kuyenera kukhala 10 ~ 20 maola.
