Powty hmoov yog siv dav siv hauv kev tsim kho thiab kho cov haujlwm rau kev kho cov kab nrib pleb, sau qhov, thiab smoothing thaj chaw. Cov neeg hais txog cellulose feem ntau siv raws li kev khi rau cov hmoov txhuv nplej siab vim lawv lub peev xwm los txhim kho kev ua haujlwm, adhesion, thiab dej khaws cia. Txawm li cas los xij, xaiv qhov tseeb ntawm cellulose rau putty hmoov tuaj yeem nyuaj vim muaj ntau txoj kev xaiv muaj nyob hauv kev ua lag luam. Hauv tsab xov xwm no, peb yuav tham txog yuav ua li cas xaiv cov kev ua kom raug rau cov neeg ua haujlwm kom raug rau patty hmoov.

Dab tsi yog cov kws qhia cellulose?

Cov neeg hais ua haujlwm ntawm cellulose yog tsev neeg ntawm polymers uas tau muab los ntawm cellulose, uas yog lub ntuj polymer pom hauv cov nroj tsuag. Lawv yog cov dej-soluble thiab muaj cov yeeb yaj kiab zoo tshaj plaws, uas ua rau lawv muaj kev sib dhos zoo tshaj plaws rau patty fws. Muaj ntau hom kev hais uas muaj kev pab muaj, txhua tus nrog nws cov yam ntxwv thiab cov txiaj ntsig zoo.

Hom ntawm cov cellulose neeg muaj kev pab

1. Methyl Cellulose (MC)

Methyl cellulose yog cov tsis-ionic cellulose cellulose ether uas tau siv dav hauv cov hmoov txhuas putty vim nws cov khoom siv dej zoo. Nws tuaj yeem txhim kho kev ua haujlwm ntawm putty hmoov, ua rau lawv yooj yim rau kev thov thiab kis. Methyl cellulose kuj tseem tiv taus kab mob kab mob kev loj hlob, ua rau nws zoo tagnrho rau kev siv hauv noo noo.

2. Hydroxypropyl Methyl Cellulose (HPMC)

HydroxyPropy cellulose yog hloov kho cellulose hloov kho ether yog ib txwm siv hauv putty hmoov vim nws cov khoom nplaum zoo tshaj plaws. Nws tseem tuaj yeem txhim kho cov dej tuav thiab ua haujlwm ntawm putty hmoov, ua rau lawv yooj yim rau kev thov thiab kis. HPMC kuj tseem tiv taus kab mob kab mob thiab muaj qhov zoo thermal stability.

3. Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose yog cov tsis-ionic cellulose ether uas nquag siv rau hauv pattty hmoov vim nws cov khoom siv thicking zoo heev. Nws tseem tuaj yeem txhim kho cov dej tuav thiab ua haujlwm ntawm putty hmoov, ua rau lawv yooj yim rau kev thov thiab kis. HEC kuj tseem tiv taus kab mob kev loj hlob thiab muaj qhov zoo thermal stability.

4. Carboxymethyl Cellulose (CMC)

Carboxymethyl cellulose yog hloov kho cellulose hloov kho uas siv tau hauv cov hmoov txhuv nplej siab vim nws cov khoom siv dej zoo. Nws tseem tuaj yeem txhim kho kev ua haujlwm ntawm putty hmoov, ua rau lawv yooj yim rau kev thov thiab kis. CMC kuj tseem tiv taus cov kab mob kev loj hlob thiab muaj kev lom zem ua kom ruaj khov.

Xaiv cov cellulose dogy rau cov hmoov txhuv nplej siab

Thaum xaiv cov cellulose dog dig rau cov hmoov txhuv nplej siab rau cov hmoov txhuv nplej siab, muaj ntau yam uas koj yuav tsum xav txog. Cov no suav nrog:

1. Daim ntawv thov txoj kev

Daim ntawv thov txheej txheem uas koj yuav siv rau cov hmoov puty yuav txiav txim seb hom cellulose ether ether tias koj yuav tsum siv. Piv txwv li, yog tias koj yuav muab tshuaj txau ua hmoov, ces koj yuav tsum siv lub cellulose ether tias muaj cov khoom siv tau zoo, xws li methyl cellulose. Yog tias koj yuav raug txiav tawm cov hmoov puty, tom qab ntawd koj yuav tsum siv lub cellulose ethere uas muaj cov nplaum nplaum zoo tshaj plaws, xws li HPMC.

2. Hom ntawm substrate

Hom ntawm substrate uas koj yuav thov cov hmoov puty los tseem yuav txiav txim siab hom cellulose ether ether tias koj yuav tsum siv. Piv txwv li, yog tias koj yuav thov cov hmoov porty, xws li pob zeb ether tias muaj cov khoom siv hluav taws xob zoo, xws li methyl cellulose. Yog tias koj yuav thov cov hmoov puTty rau qhov chaw tsis-ntxeem tau, xws li hlau lossis iav, koj yuav tsum siv cov nplaum nplaum zoo heev, xws li HPMC.

3. Cov Khoom Siv Xav Tau

Cov khoom xav tau ntawm cov hmoov putty tseem yuav tseem txiav txim siab txog hom cellulose ether tias koj yuav tsum siv. Piv txwv li, yog tias koj xav tau cov hmoov uas muaj sia muaj sia kom muaj cov khoom siv hluav taws xob zoo, tom qab ntawd muaj cov khoom siv tshuaj tua me me, xws li methyl cellulose. Yog tias koj xav tau cov hmoov nplaum ua kom muaj cov nplaum nplaum uas koj yuav tsum siv lub cellulose ethere uas muaj cov nplaum nplaum zoo tshaj plaws, xws li HPMC.

4. Ib puag ncig tej yam kev mob

Yuav siv cov hmoov ib puag ncig uas muaj cov hmoov txhuas uas muaj zaub mov rau ib qho tseem yuav txiav txim siab hom cellulose ether ether tias koj yuav tsum siv. Piv txwv li, yog tias cov hmoov putty yuav siv rau hauv ib puag ncig huab cua, ces koj yuav tsum tau tiv thaiv kab mob methyl, xws li methyl cellulose lossis hpmc. Yog tias cov hmoov putty yuav siv rau hauv qhov chaw kub, tom qab ntawd koj yuav tsum siv lub cellulose ether uas muaj cov zoo thermal stability, xws li HEC lossis CMC.

Xaus

Xaiv lub cellulose dogy rau cov hmoov txhuv nplej siab rau cov hmoov txhuv nplej siab yog qhov tseem ceeb rau kev ua tiav cov khoom uas xav tau thiab ua tau zoo ntawm cov khoom. Thaum xaiv cov cell dogy ether, koj yuav tsum xav txog cov txheej txheem ntawm cov ntawv thov, hom substrate, yam khoom xav tau, thiab ib puag ncig. Los ntawm kev xaiv cellulose tsim nyog ether, koj tuaj yeem ntseeg tau tias koj cov khoom siv uas muaj zog muaj zog, ua kom zoo rau kev kho cov kab nrib pleb, kev ua kom zoo nkauj, thiab cov chaw ua haujlwm smoothing hauv kev tsim kho thiab kho cov haujlwm.
