Kodi mitundu yosiyanasiyana ya cellose yomwe yapezeka konkriti ndi iti?

Cellulose ether ndiowonjezera owonjezera owonjezera omwe amagwiritsidwa ntchito kwambiri ku konkriti ndi matope kuti athe kusintha zinthu zawo. Ntchito zazikuluzikulu za cellulose ethertete zimaphatikizapo kukula, kusungunuka kwamadzi, kuchedwa kukhazikika, kukonzanso kugwirira ntchito, etc.

1. Methyl cellulose (MC, Methyl Cellulose)
Methylcellulose ndiye mtundu wofala kwambiri wa ethel ether, yomwe imapangidwa ndi magulu ena a hydroxyl mu cellulose ndi magulu a methoxy (-Och3). Methylcellulose makamaka imatenga gawo la kukhazikika kwamphamvu ndi madzi osungirako ma conrete. Imatha kusintha kwambiri kuwoloka konkriti, kuwonjezera chipilala cha konkriti, kuchepetsa magazi, potero kukonza magazi ndi kulimba kwa konkriti. Kuphatikiza apo, methylcelluloser ilinso ndi katundu wabwino wopanga mawonekedwe, omwe amatha kusintha bwino kusalala ndi kufanana kwa konkriti.

2. Hydroxypropyl Meth Celyose (HPMC, Hydroxypropyl Methyl Celyose)
Hydroxypropyll methylcellulose imapangidwa poyambitsa hydroxypropyl (-ch2chohch3pkyl (-ch2chohch3ppyl (-ch2chohch3) pamaziko a methylcellulose. HPMC ili ndi madzi abwino osasungidwa komanso zipatso zokumba, choncho zimawonetsa kulimba mwamphamvu komanso katundu wa sag-sagrete. Imatha kukhalabe ndi magwiridwe abwino amadzi otentha kwambiri ndikuletsa madzi ku konkriti kuti asakuphe msanga, motero kuchepetsa kupezeka kwa ming'alu. Kuphatikiza apo, hpmc amathanso kuchedwetsa kuthamanga kwa simenti hydrate, kulola konkriti kukhala ndi nthawi yayitali ndikuwongolera zomanga.

3. Hydroxethyl cellulose (Hec, Hydroxethyl Cellose)
Hydroxyethyl cellulose imapangidwa poyambitsa magulu a hydroxyethyl (-ch2ch2oh) mu mamolekyulu. Ntchito yayikulu ya Hec mu konkriti ikukula ndikuwongolera zomangira zogwiritsira ntchito konkriti. Poyerekeza ndi cellulose ina, hec imakhala yokhazikika mu mikhalidwe ya alkalinine, motero imagwiritsidwa ntchito kwambiri ku konkriti. Zimatha kukonza magwiridwe antchito a konkriti ndikuwonjezera mphamvu ya konkriti. Makamaka pamalo osakanizidwa-osakanizika omwe amafunikira kusungidwa kwakanthawi kapena mayendedwe, fulu amatha kupewa kuchepetsedwa ndi magazi.

4. Hydroxypropyl Cellulose (HPC, Hydroxypropyl Cellose)
Hydroxypyl cellulose imapangidwa ndikuyambitsa gulu la hydroxypyl (-ch2choch3) mu cellulose molekyulu. Zofanana ndi hpmc, hpc zimakula bwino komanso zosafunikira zamadzi. Kuphatikiza apo, HPC imakhalanso ndi kukhazikika kwa matenthedwe ndi mawonekedwe a filimu, omwe amatha kukonza zovuta komanso kulimba kwa konkriti. Pansi pa kutentha kwambiri, hpc imatha kuchepetsa kwambiri madzi ku konkriti, potero kupewa kuwonongeka kwa konkriti.

5. Hydroxyethyl Methyl Cellose (hemc, hydroxyethyl methl cellouse)
Hydroxyathylmethylcellulose imapangidwa poyambitsa magulu a hydroxyethyl mu methylcellulose. Hemc amaphatikiza mawonekedwe a Hec ndi MC, ali ndi madzi abwino osakhazikika, ndipo amathanso kukonzanso kugwirira ntchito ndi kukhazikika kwa konkriti. Amagwiritsidwa ntchito kwambiri ku konkriti, makamaka pamatoto odzilimbitsa okha matope komanso matope. Hemc imatha kukonza bwino ntchito zomanga, kuchepetsa kuchepa chinyezi mu matope, ndikuletsa minyewa mutayanika.

6. Ethyl cellulose (ECYYL Cellose)
Ethylcellulose imapangidwa ndikusintha magulu a hydroxyl mu molekyulu ya cellulose ndi magulu a ethoxy (-OC2h5). EC siigwiritsa konkriti koyambirira, koma imagwira konkriti yapadera kwambiri monga konkriti wa konkriti waluso komanso wokha. EC ili ndi mphamvu yolumikizira komanso yolumikizira ndipo imatha kusintha nyonga ndi kupindika konkriti. Kuphatikiza apo, ECnso ilinso ndi mankhwala osokoneza bongo komanso kukhazikika kwa matenthedwe, motero imatha kugwiritsidwa ntchito bwino m'malo ena.

7. Methyl hydrothyl cellulose (mhec, methyl hydrothyl cellulose)
Methyl hydrothyl cellulose imapanga mawonekedwe a MC ndi Hec ndipo ali ndi kukula kwabwino, kusungidwa kwa madzi ndi kuwunikira madzi. Udindo waukulu wa manc mu konkriti ndikuwongolera katundu wogwiritsira ntchito komanso kuphwanya konkriti. Zimagwiritsidwa ntchito kwambiri pakudzilimbitsa konkriti ndikukonza matope.

Cellulose eders amagwiritsidwa ntchito kwambiri ku konkriti ndipo ndi mitundu yosiyanasiyana. Mitundu yosiyanasiyana ya cellulose imakhala ndi mitundu yosiyanasiyana ya mankhwala ndi katundu wa mankhwala ndipo amatha kukwaniritsa zosowa zosiyanasiyana. Kusankha mtundu wa extheuse woyenera kumatha kukonza kwambiri kugwiritsidwa ntchito, nyonga ndi kukhazikika kwa konkriti, potengera kudalirika ndi kudalirika kwa ntchito zomanga. Pogwiritsa ntchito, ndikofunikira kusankha mtundu ndi mlingo wa etheluse ether zofunikira pazachilengedwe komanso malo omanga kuti akwaniritse bwino kwambiri.
