Kodi ma cellose omwe amagwiritsidwa ntchito nthawi zambiri amagwiritsidwa ntchito ndi simenti?

Te cellulose eya amagwira ntchito yofunika kwambiri pantchito yomanga, makamaka kugwiritsa ntchito konkriti. Izi zowonjezerazi zimapangitsa magwiridwe ake ndi konkriti, kupereka mapindu monga moyenera monga kukonza bwino, kusungidwa kwamadzi ndi kutsatira. Zina mwa mitundu yosiyanasiyana ya cellulose et, ena ambiri amagwiritsidwa ntchito pamakonzedwe konkriti.

1.hydroxyethylmethycelulose (hemc):

Hydroxyethyl Methylcellulose, yomwe imadziwika kuti hemc, ndi cellulose yosungunuka yamadzi ether yogwiritsidwa ntchito kwambiri m'makampani omanga. Imapezeka ndi kusintha kwa mankhwala kwa cellulose. Hemc amadziwika kuti ndi madzi ake abwinobwino, ndikupangitsa kukhala zowonjezera mu zosakanikirana. Zimathandiza kupewa kuyanika kwa simenti, kuwonetsetsa bwino komanso kumaliza.

Kuphatikiza apo, hemac amachita ngati wokulirapo, kukulitsa maluso odziwa bwino. Katunduyu ndi wopindulitsa makamaka pakugwiritsa ntchito njira, monga kupaka ndikupanga ndikupereka, komwe kumapangitsa kuti zisungunuke ndikuchepetsa.

2.hydrocypropylmethylcellulose (hpmc):

Hydroxypypyl methylcellulose (hpmc) amagwiritsidwa ntchito mu celluuse yopezeka konkriti. Monga hemc, hpmc ndi polymer osungunuka madzi kuchokera ku cellulose. Imapereka maubwino osiyanasiyana kuphatikizapo kusungidwa kwamadzi, kugwiritsidwa ntchito ndi kutsatira.

Mukugwiritsa ntchito konkriti, HPMC imagwira ngati rhelology yosintha, ikukhudza mawonekedwe ndi kusinthika kwa osakaniza. Uku ndikofunikira kwambiri kuti mudzilowe nokha komanso mafoni owonda. Kuphatikiza apo, hpmc imathandizira kukonza cholumikizira cha osakaniza, potero onjezani mphamvu ndi kukhazikika kwa konkire.

3. Methyl cellulose (MC):

Methylcellulose (MC) ndi ether ether yochokera ku cellulose yachilengedwe kudzera njira zingapo zamankhwala. Amadziwika ndi kusungunuka madzi ndi katundu wamafilimu. Mukugwiritsa ntchito konkriti, MC nthawi zambiri imagwiritsidwa ntchito ngati thickiner ndi wogulitsa madzi.

Mc mwakusintha tsankho komanso magazi m'mabanja osakanikirana ndipo zimatsimikizira ngakhale kugawa anthu okalamba. Mphamvu yake yopanga mafilimu imathandiziranso kutsatira magawo osiyanasiyana. Kuphatikiza apo, MC imadziwika kuti imagwirizana ndi zinthu zina zomanga, zimapangitsa kukhala konkriti yosinthasintha.

4. Carboxymethylcellulose (CMC):

Carboxymethylcellulose (cmc) ndi ethel ether ndi ma carboxymethyl magulu omwe amaphatikizidwa ndi msana wa m'Chunji. Pomwe CMC siili monga momwe zimagwiritsidwira ntchito konkriti monga cellulose ina, imatha kupeza mapulogalamu omwe ali ndi zochitika zina.

Ku konkriti, CMC imagwiritsidwa ntchito posungira madzi ndi kukula kwake. Zimathandizira kukonza chipilala cha kusakaniza ndikuchepetsa kutsika chinyezi pakakhazikika. CMC imagwiritsidwa ntchito nthawi zambiri m'makona apadera, monga omwe amagwiritsidwa ntchito poizona.

5.thyyhydroxyelycellulose (Ehec):

Ethyl hydrothyl cellulose, yomwe imadziwika kuti Ehec, ndi ethel ethel ethel celluse ndi kuphatikiza kwa ethyl ndi hydroxyethyl magantimitalthl. Imakhala yamtengo wapatali chifukwa chosinthasintha pankhani zosiyanasiyana, kuphatikizapo zomanga.

Ku konkreti, anthu amagwira ngati wothandizira madzi, kuonetsetsa kuti osakaniza amakhalabe otalikirana kwakanthawi. Zimathandizanso kuti zizikhala ndi mphamvu komanso zimachepetsa mwayi wosokoneza. Ehec nthawi zambiri amagwiritsidwa ntchito mu malonda a Tile, mafayilo ndi zinthu zina zopangidwa.

Cellulose eds amagwira ntchito yofunika kwambiri pakuwongolera makona a konkriti pantchito zomangamanga. Cellulose yogwiritsidwa ntchito cell, monga hemoc, hpmc, mc, cmc, cmc, reaction yopindulitsa kuphatikizapo konkriti yolimba. Kumvetsetsa zomwe zili mu etherse iliyonse pa cellulose kungagwiritsidwe ntchito molondola mu ma concretiction osiyanasiyana kuti mukwaniritse zosowa zosiyanasiyana zomanga.
