Seimwe chinhu chakakosha kuvaka zvinhu zvinowedzera, cellulose ether inoshandiswa zvakanyanya muindasitiri yekuvaka, kunyanya muPutties uye maCoatings. Izvo zvakasarudzika zvemakemikari zvivakwa uye mabasa zvinoita kuti ive yakakosha musanganiswa mukuvandudza iyo yekushambadzira kwekutyisa kune akasiyana substrates. Mabasa makuru e cellulose aungana anosanganisira kurerutsa, kuchengetwa kwemvura, kumiswa uye kusimudzira kuderera. Kuwedzera cellulose etty kune iyo putty formula kunogona kugadzirisa zvakanyanya kushanda kwekushanda kwekutyisa uye kusimudzira kuderedza kwayo kune iyo substrate.
1. Hunhu hwe cellulose ether uye mechanism yemutoro chiito
Cellulose ether rudzi rwekutsamwa kwechisikigo cellulose inoumbwa methyl cellulose (hpmc), hpmxeththyl cellulose (hec), nezvimwe. Cellulose ether mamorekuru vane yakanaka mvura solubility uye yakakora midziyo, uye inogona kuumba yakagadzikana colodal mhinduro kana yakasanganiswa nemvura. Sezvo cellulose ether mamorekuru ane hydrophilic uye hydrophobic mapoka, yavo solubility uye viscosity mumvura inogona kuvandudza zvinobudirira kuita kwekuvaka.
Chiitiko chechiitiko chemhereme ye cellulose ether mune putty inonyanya kuratidzwa mune zvinotevera zvinhu:
Kudzokorora kwemvura: Cellulose ether kunogona kuridza yakanakisa mvura yekuchengetedza mune iyo putty formula uye kudzivirira mvura kubva mukubuda nekukurumidza mushure mekuvaka. Izvi zvinobvumira iyo putty kugovera kunyorova zvakanyanyisa panguva yekuomesa procing, nekudaro kuderedza kupaza uye kubatsira kuvandudza kudengenyeka kweiyo putty kune substrate.
Kukakavara: Iko kukonzeresa kwemheremellose ether kunogona kuwedzera kuwirirana kweiyo putty kuitira kuti irege kusvetuka panguva yekuvakwa pamadziro emadziro kana kuti masheya. Ichi chiitiko chakakosha kune kunyange kunyatsoita uye kuvaka kuvaka kwekutyisa.
Lubricose ether inogona kuvandudza iyo lubricity yePutty, ichiita kuti zvivakwa zvakatsetseka, kuderedza kuramba panguva yekuvaka, uye nekudaro zvakakodzera zvinhu zvacho.
Anti-sag: cellulose ether ane mhedzisiro yekuvandudza kudengenyeka kwekutyisa, kuita kuti putty isingasviki pamadziro, uye inogona kuramba yakabata zvakanaka kunyangwe mune yakanyanya kupisa, yakakwirira-yakakwirira nzvimbo dzekuvaka. Adhishing Eress.
2. Mhedzisiro ye cellulose ether pane putty ADHesion
Kudonhedza kwePutty chinhu chakakosha chinokanganisa maitiro ake ekuvaka uye hupenyu hwebasa. Kuwedzerwa kwe cellulose ether kunopa putty inotevera yakanakira zvakanakira:
Kuvandudza iyo yakanyorova yeiyo substrate pamusoro: cellulose ether mamorekuru anoparadzaniswa mune iyo putty, iyo inogona kunyatso kuderedza kusawirirana pakati peiyo putty uye nekukasira, nekudaro zvichikura mhedzisiro yeiyo putty pane subty. Iyi yekunyorova inosimbisa kugona kwekupinzwa kwekutyisa, zvichiita kuti zvive nyore kune iyo fungidziro yekupinda mumatikiti madiki ezvipfuyo, achivandudza kudenha.
Kuvandudzwa kuDhipatimendi Remanyama: Iyo inokonzeresa uye yemvura-yekuchengetedza madhara e cellulose inogonesa iyo putty kuumba yunifomu yekuvhara pamusoro peiyo substrate, nekudaro ichisimudzira kudedera kwepanyama. Iri basa harungagone kudzivirira iyo kuderera kubva pakuporesa panguva yekuporesa, asi zvakare kudzivirira kuumbwa kwemapundu pakati peiyo putty uye zvigadziko zvemukati, zvichiratidza kusungwa.
Yakavandudzwa kupaza kupokana: Cellulose ether inogona kuvandudza kuchinjika kwekutyisa uye kuderedza kushushikana pane iyo putty layer inokonzerwa nekuchinja mukushisa uye nekunyorova, nekudaro kudzivirira kupaza. Uku kushanduka kunobvumira kushushikana kwemukati kunogadzirwa neyekukutu panguva yekuomesa kuti ibatwe uye kuparadzira, nekukasira kugadzirisa kudenha pakati peiyo putty uye substrate.
Kuvandudza kudzikisira kwezano Pasi pemamiriro ezvinhu akaomarara senge tembiricha uye humbowo hwakareba, mwero wekuyerera kwemvura mune putty layer anodzikira, achivimbisa kudedera kwekutyisa.
3. Kushandiswa kwe cellulose ana vana pane akasiyana substrates
Substrate dzakasiyana ine zvakasiyana kuderedza zvinodiwa putty. Kuwedzerwa kwe cellulose ether kunogona kugadzirisa zvakanyanya kuderedza kwekutyisa kune zvinotevera kufanana.
SEment Base zvinhu: Iyo pamusoro peiyo yemadziro emadziro haina kunaka uye inobata zvakanyanya. Cellulose ether inogona kuwedzera kudengenyeka kweiyo denty kune iyo siment base zvinhu uye kugadzirisa iyo yekuvhara mhedzisiro yeiyo putty pane simenti yemadziro.
Gypsum Base Zvinyorwa: Kumusoro kweGypsum Base zvinhu kunotsvedza, uye kuremerwa uye kwemvura zvinokonzeresa cellulose inogona kubatsira iyo yunifomu yekuvhara zvinyorwa zveGypsum kuti ubvise putty kubva pakudonha kana kupaza.
Wood Supptrate: Wood ine mvura yakasimba yekukanda uye shrinkage zvivakwa. Kuwedzera kwe cellulose ether kunogona kuwedzera kuchinjika uye kuchengetwa kwemvura kwekutyisa uye kudzivirira iyo putty layer kubva pakudonha nekuda kwehuni yekushongedza kwehuni.
Substrate Substrate: Iyo Simbi Yakatsiga inotsvedza uye isingaiti
Kuwedzerwa kwemaserulose ether kunovandudza kudenha kweiyo putty, ichiita kuti ive yakakodzera kune dzakasiyana siyana substrates. Kuburikidza nemabasa akawanda akadai sekuremerwa, kudzokorora kwemvura, kuiswa kwemvura uye kugadzirisa manyorerwo, cell. Naizvozvo, cellulose ether yave yakakosha kiyi yekuvakwa kwekuvaka, kupa zvinhu zvekutamba zvine simba uye kusimba kwakasimba uye kusimba.
