CMC inoshandisa muPaints uye Coatings Indasitiri

Paint giredhi carboxymethyl cellulose sodiumane kukora kwakanaka, kupararira uye kugadzikana, kunogona kuvandudza viscosity uye rheology yezvipfeko, saka inoshandiswa zvakanyanya mumhando dzakasiyana-siyana, latex coatings, mvura-based exterio uye mukati mukati, kukanda machira uye zvichingodaro.

Kushandisa pakarepopendi giredhi carboxymethyl cellulose:

Iyo inonzi instant solution inoreva kuti CMC poda inogona kuparadzirwa uye kunyungudutswa nekukurumidza mumvura ine mvura patembiricha yekamuri, iyo yakasiyana neyakajairwa mhando yeCMC inonyungudika zvishoma nezvishoma (iyo yakajairika mhando yeCMC inoda kanenge 2-3 maawa epamusoro- kukurumidza kubvongodza kunyungudika zvachose). Iyo viscosity yegiredhi rekuvhara ipapo carboxymethyl cellulose CMC haizongosvika pakuona kwayo chaiko nekukurumidza kupera kwehupfu, uye ichave mumaminitsi gumi-15 mushure mekupera kweiyo viscosity, kuumbwa kweiyo viscosity chaiyo inogona kuwana colloid. . Pamusoro pezvo, iyo colloid kugadzikana kweCMC yekukurumidza iri nani pane iyo yeyakajairwa CMC ine zvakafanana zvakatemwa.

Instantsolublecarboxymethyl cellulose CMC inoshandiswa zvakanyanya mumhando dzese dzemvura-based coatings, senge chena latex, latex pendi, putty, pendi yekuyamura, pendi yematombo echisikigo, nezvimwe.

Zvakanakira zvependi giredhi carboxymethyl cellulose:

A) Kupfekedza hakuna kuiswa uye kunogona kuchengetedzwa kwenguva yakareba;

B) Inogona kupa inokurumidza-kunyungudika yakakosha zvigadzirwa zvekuputira maapplication muminda yakakosha;

C) Kunyatso gadzirisa rheology ye glaze slurry, fambisa glaze application, uye ita iyo glaze slurry munzvimbo yakagadzikana yekupararira;

D) Kunyatso vandudza glaze simba uye kutsvedzerera kudzivirira deglazing;

E) Iva nechokwadi chekudhinda mukugadzirwa kwekudhinda glaze, uye maitiro akadhindwa akajeka uye akanaka;

F) Pachave pasina chinovharira mukudhinda glaze kudhinda maitiro, CMC ine yakanaka solubility yemvura uye inenge isina zvisinganyunguriki zvinhu zvakaita sefiber tsvina;

Paint giredhiCMCcarboxymethyl cellulose dissolution nzira:

Thependi giredhi carboxymethyl cellulose inosanganiswa yakanangana nemvura uye inogadzirirwa mune paste glue kuti ishandiswe gare gare. Chiyero mukugadzirisa coating carboxymethyl cellulose paste adhesive, kutanga nekusanganisa zvinorimwa mucylinder kuti ubatanidze imwe huwandu hwemvura yakachena, pachena pasi pemamiriro ekugadzirisa mudziyo, iyo yekuputira yecarboxymethyl cellulose zvishoma nezvishoma uye zvakaenzana kune zvinongedzo mucylinder. , kurudzira nguva dzose, gadzira pendi carboxymethyl cellulose uye fusion yemvura level, carboxymethyl cellulose inogona kunyunguduka zvakakwana coating level. Pakunyunguduka pendigiredhi carboxymethyl cellulose, chikonzero chekupararira zvakaenzana, uye nguva dzose ichikurudzira, chinangwa "kudzivirira pendi giredhi carboxymethyl fiber uye mvura kusangana, agglomeration, agglomeration, kuderedza pendi giredhi carboxymethyl cellulose solubility dambudziko", uye kunatsiridza kunyungudika mwero wependi giredhi carboxymethyl. cellulose. Kukurudzira nguva uye pendi giredhi carboxymethyl cellulose yakakwana kupera nguva haienderane, ipfungwa mbiri, kazhinji kutaura, kubvongodza nguva ipfupi kwazvo pane pendi giredhi carboxymethyl cellulose yakazara kupera nguva, nguva inodiwa zvinoenderana nemamiriro chaiwo.

Sarudza nguva inokurudzira pamusana pe: kana carboxymethyl cellulose mumvura yakapararira zvakaenzana, hapana chinhu chakakura chebundu chiri pachena, iwe unogona kurega kubvongodza, kuitira kuti carboxymethyl cellulose uye mvura igare yakagadzikana yekupindirana, mutual fusion.

Sarudza iyo carboxymethyl cellulose kupera kwakazara kwenguva inodiwa pahwaro hwezvinotevera zvinhu:

(1) pendi giredhiCMCcarboxymethyl cellulose uye mvura zvakabatanidzwa zvachose, uye hapana kupatsanurwa kwakasimba-mvura pakati pavo;

(2) Mushonga wakavhenganiswa uri muchimiro chakafanana, uye pamusoro pacho pakatsetseka;

(3) Ruvara rwemusanganiswa wealeurone uri pedyo nekusina ruvara uye pachena, uye hapana chinhu chegranular mu aleurone. Kubva pagiredhi rependeCMCcarboxymethyl cellulose inoiswa musanganiswa tangi nemvura, kune pendi giredhiCMCcarboxymethyl cellulose yakanyungudika zvachose, nguva inodiwa pakati pegumi kusvika maawa makumi maviri.
