Ntchito ndi kugwiritsa ntchito cellulose ether mumatope osakaniza okonzeka

Ma cellulose ether ali ndi ntchito zitatu izi:

1) Ikhoza kulimbitsa matope atsopano kuti ateteze tsankho ndikupeza thupi lapulasitiki lofanana;

2) Imakhala ndi mphamvu yolowera mpweya, ndipo imathanso kukhazikika yunifolomu ndi ma thovu abwino a mpweya omwe amalowetsedwa mumatope;

3) Monga chosungira madzi, chimathandiza kusunga madzi (madzi aulere) mumtondo wochepa thupi, kotero kuti simenti ikhoza kukhala ndi nthawi yochuluka ya hydrate pambuyo pomanga matope.

Mumatope osakanizika owuma, methyl cellulose ether imagwira ntchito yosunga madzi, kukulitsa komanso kukonza ntchito yomanga.Kuchita bwino kosungirako madzi kumatsimikizira kuti matopewo sangapangitse mchenga, ufa ndi kuchepetsa mphamvu chifukwa cha kusowa kwa madzi ndi hydration yosakwanira simenti;kukhuthala kumawonjezera mphamvu zamapangidwe a dothi lonyowa, ndipo luso loletsa kugwedezeka kwa zomatira matailosi ndi chitsanzo;Kuphatikiza kwa maziko a cellulose ether kumatha kusintha kwambiri kukhathamiritsa konyowa kwa matope onyowa, ndipo kumakhala ndi kukhuthala kwabwino ku magawo osiyanasiyana, potero kuwongolera magwiridwe antchito a matope onyowa ndikuchepetsa zinyalala.

Mukamagwiritsa ntchito cellulose ether, ziyenera kukumbukiridwa kuti ngati mlingo uli wochuluka kwambiri kapena kukhuthala kwake ndikwambiri, kufunikira kwa madzi kumawonjezeka, ndipo zomangamanga zidzamva zolemetsa (zomata zomata) ndikugwira ntchito kudzachepa.Cellulose ether idzachedwetsa nthawi yoyika simenti, makamaka pamene zomwe zili pamwambazi, kuchedwetsa kumakhala kofunika kwambiri.Kuphatikiza apo, ether ya cellulose idzakhudzanso nthawi yotseguka, kukana kwa sag ndi mphamvu ya mgwirizano wamatope.

Ether yoyenera ya cellulose iyenera kusankhidwa muzinthu zosiyanasiyana, ndipo ntchito zake zimakhalanso zosiyana.Mwachitsanzo, ndi bwino kusankha MC yokhala ndi mamasukidwe apamwamba pamamatira a matailosi, omwe amatha kutalikitsa nthawi yotsegulira ndi nthawi yosinthika, ndikuwongolera magwiridwe antchito a anti-slip;mumatope odzipangira okha, ndibwino kuti musankhe MC yokhala ndi kukhuthala kochepa kuti musunge madzi a matope, ndipo nthawi yomweyo Imachitanso kuti muteteze stratification ndi kusunga madzi.Ma ether a cellulose oyenerera ayenera kutsimikiziridwa molingana ndi malingaliro a wopanga ndi zotsatira zofananira zoyesa.

Kuphatikiza apo, ether ya cellulose imakhala ndi chithovu chokhazikika, ndipo chifukwa cha kupanga filimu koyambirira, imayambitsa khungu mumatope.Mafilimu a cellulose ether angakhale atapangidwa panthawi kapena atangoyamba kumene, ufa wa rabara usanayambe kupanga filimu.Chofunikira pa izi ndi ntchito yapamtunda ya cellulose ethers.Popeza thovu la mpweya limabweretsedwa ndi agitator, cellulose ether imatenga mawonekedwe pakati pa thovu la mpweya ndi matope a simenti kuti apange filimu.Ma nembanembawo anali akadali onyowa ndipo motero amasinthasintha kwambiri komanso okhazikika, koma zotsatira za polarization zimatsimikizira momveka bwino dongosolo ladongosolo la mamolekyu awo.

Popeza cellulose ether ndi polima wosungunuka m'madzi, imasamukira pamwamba pa matope omwe amalumikizana ndi mpweya ndi kutuluka kwa madzi mumtondo watsopano kuti apange kulimbikitsana, motero kuchititsa khungu la cellulose ether pamwamba pa matope atsopano.Chifukwa cha khungu, filimu yowonongeka imapangidwa pamwamba pa matope, omwe amafupikitsa nthawi yotseguka ya matope.Ngati matailosi amaikidwa pamwamba pa matope nthawi ino, wosanjikiza wa filimuyi adzagawidwanso mkati mwa matope ndi mawonekedwe pakati pa matailosi ndi matope, potero kuchepetsa mphamvu yogwirizanitsa.Khungu la cellulose ether lingathe kuchepetsedwa mwa kusintha ndondomekoyi, kusankha ether yoyenera ya cellulose ndi kuwonjezera zina zowonjezera.
