Cellulose anainininikama vanoita basa rakakosha muboka rekuvaka, kunyanya mukushandisa kongiri. Izvi zvinowedzera zvinowedzera kuita uye hunhu hwekongiri, kupa zvinobatsira sekuvandudza kushanda, kudzokorora kwemvura uye kuderedza. Pakati pemhando dzakasiyana-siyana dze cellulose avaneta, vamwe vanowanzoshandiswa mukuumbwa kongororo.
1.hydroxyTrylmethylcellose (HEMC):
HydroxytHyl methylcellose, inowanzozivikanwa seHemc, inguva yemvura-sollo cellulose ther yakashandiswa zvakanyanya mune yekuvaka indasitiri. Inowanikwa nemakemikari kugadziridzwa kwemheremalose. Hemc inozivikanwa nekuda kweiyo yakanakisa mvura yekuchengetwa kwemvura, ichiita kuti ive inoshanda mukuratidzira mumusanganiswa wekongiri. Iyo inobatsira kudzivirira kuoma kwekupedza kongiri, ichiratidza kuti kushanda kwakanaka uye kupedzisa.
Uye zvakare, hemc zviito seanotenda, inowedzera iyo visikopo yemusanganiswa wekongiri. Ichi chivakwa chinonyanya kubatsira mukushandisa vertical, sekuparadza uye kushandurwa, uko kwakavandudzwa kuderedza uye kuderedza kudedera kunodiwa.
2.Hydroxypronylmethylcellose (HPMC):
HydroxyPropyl methylcellose (HPMC) ndeimwe yakashandiswa zvakanyanya cellulose ether in concrete mafomu. Sa hemc, hpmc ipurusi remvura rinodzungudzwa rinotorwa kubva ku cellulose. Iyo inopa huwandu hwakawanda hwezvakanaka zvinosanganisira zvakavandudza kuchengetedza kwemvura, kushanda uye kuderedza.
Muchirongwa chekongiri, HPMC zviito senge rheology modifier, ichikanganisa kuyerera uye deformation maitiro emusanganiswa. Izvi zvinonyanya kukosha pakuzviisa wega uye zvakaonda-jasi motsi. Pamusoro pezvo, HPMC inobatsira kuvandudza kuderedza musanganiswa, nekudaro zvichikura simba uye kusimba kweakarapwa kongiri.
3. Methyl Cellulose (MC):
MetHylcellose (MC) ndeye cellulose ether inotorwa kubva kune yakasikwa cellulose kuburikidza neyekutevedzana kwemakemikari maitiro. Iyo inoratidzirwa neyakagadziriswa mvura uye mafirimu-ekuumba midziyo. MuConcrete Zvikumbiro, MC inowanzoshandiswa seanotenderedza uye mvura inochengetedza mumiriri.
MC inoshanda zvinodzivirira kusaririra uye kubuda ropa mumidziyo yemakonzo uye inovimbisa kunyange kugovera kwekuunganidzwa. Zvivakwa zvemufirimu-zvemufirimu zvinogadzira zvakare zvinovandudza kudengenyeka kune dzakasiyana siyana. Pamusoro pezvo, mc inozivikanwa nekuenderana kwayo nezvimwe zvinhu zvekuvaka, zvichiita kuti zviite zvakawandisa muzvimiro zvekongiri.
4. CarboxyMethylcellose (cmc):
CarboxyMethylcellose (CMC) is cellulose ether ne carboxymethyl mapoka akasungirirwa kune cellulose backbone. Ipo CMC isiri inowanzo shandiswa mukongiri seimwe cellulose anaitani, inogona kuwana maficha mune mamwe mamiriro ezvinhu.
Mukongiri, cmc inoshandiswa pakuchengetwa kwemvura kwayo uye inokakavara. Iyo inobatsira kuvandudza kubatana kwemusanganiswa uye kuderedza kurasikirwa kwekunyorova panguva yekuisa. CMC inowanzoshandiswa mune inokosha kongiri mafambiro, yakadai seiya inoshandiswa mukushandisa mafomu ekuramba.
5.thylhydroxylcelcellose (ehec):
Etirayl hydroxyll cellever, inozivikanwa seEHEC, ndeye cellen ether ine musanganiswa weEthayl uye hydroxytethsl subsituets. Iyo inokosheswa kuti isingaenzaniswi mune dzakasiyana siyana dzekushandisa, kusanganisira kuvaka.
Mu kongiri, ehec zviito seyemumiriri wekuchengetedza mvura, anoona kuti musanganiswa unoramba wakasununguka kwenguva yakareba. Izvo zvinobatsirawo kuvandudza chisungo simba uye zvinoderedza mukana wekupaza. Ehec inowanzo shandiswa mumatanda anomhara, mongwe uye zvimwe zvigadzirwa zvekumisikidzwa.
Cellulose eterolose vater vanoita basa rakakosha mukuvandudza mashandiro ekongiri mune zvekuvaka maapplication. Kazhinji washandiswa cellulose ana mherem cell, selmc, hpmc, mc, cmc uye ehec, ipa mhando yezvakanaka zvinosanganisira kudzora kudzorera, kudzokorora kwemvura, kujaira uye kusimba kwakazara kwekongiri yemakongiri. Kunzwisisa zvakananga zvivakwa zvega ega cellulose ether chinogona kushandiswa zvinobudirira mune dzakasiyana kongiri concrete mafomu ekusangana nezvakaringana zvido zveindasitiri yekuvaka.
