Chii mhedzisiro yeSodium Carboxymeythyl Cellulose paMota

Sodium carboxymethyl cellulose (CMC) ndeyekuwedzera kune zvakasiyana-siyana iyo inowana mashandisirwo mumaindasitiri akasiyana siyana, kusanganisira kuvaka. Munzvimbo yezvigadzirwa zvekuvaka, CMC inoita basa rakakosha mukuvandudza zvivakwa uye kuita kwedhaka, chinhu chakakosha chinoshandiswa mukugadzira masonry, plastering, uye mamwe mabasa ekuvaka. Ichi chinyorwa chinoongorora mhedzisiro ye sodium carboxymethyl cellulose padhaka, ichirondedzera mabasa ayo, mabhenefiti, uye mashandisiro muindasitiri yekuvaka.

Nhanganyaya kune Mortar:

Doka chinhu chakaita senamira chinoumbwa nemasungiro esimende, akaunganidza, mvura, uye zvakasiyana-siyana zvinowedzera. Inoshanda sechisungo chekubatanidza kune masonry units, sezvidhinha, matombo, kana kongiri zvidhinha, zvichipa kubatana, simba, uye kusimba kune zvinoguma zvivakwa. Doka rakakosha pakuvaka madziro, migwagwa, uye zvimwe zvinhu zvekuvaka, zvichigadzira musana wezvimiro zvezvirongwa zvakawanda zvekuvaka.

Sodium Carboxymethyl Cellulose (CMC):

Sodium carboxymethyl cellulose (CMC) i polymer inonyungudika nemvura inotorwa kubva ku cellulose, yakasikwa polysaccharide inowanikwa muchirimwa sero madziro. CMC inogadzirwa nekurapa cellulose ine sodium hydroxide uye monochloroacetic acid, zvichikonzera musanganiswa wemakemikari une zvimiro zvakasiyana. CMC inoshandiswa zvakanyanya seyakakora, stabilizer, binder, uye mumiriri wekuchengetedza mvura mune akasiyana maindasitiri ekushandisa, kusanganisira chikafu, mishonga, zvizorwa, uye zvekuvakisa.

Mhedzisiro yeCMC pamatope:

1. Kuchengeta Mvura:
   • CMC inoshanda semumiriri wekuchengetedza mvura mumatope maumbirwo, ichibatsira kuchengetedza yakaringana mwando panguva yekusanganisa, kushandisa, uye kurapa matanho.
   • Nekutora uye kubata mamorekuru emvura, CMC inodzivirira kukurumidza kubuda uye kupera simba kwedhaka, kuve nechokwadi chekuti hydration yakakwana yemasimende uye kusimudzira kurapa kwayo.
   • Uku kukwidziridzwa kwekugona kuchengetedza mvura kunovandudza kushanda, kunoderedza shrinkage, uye kuderedza kuputika mudhaka rakaporeswa, zvichitungamira kukubatana kuri nani uye kusimba kwenguva refu kwezvivakwa zvemasonry.
2. Kuvandudzwa Kwekushanda:
   • Kuwedzerwa kweCMC kune dhaka kunowedzera kushanda kwayo uye mapurasitiki, zvichiita kuti zvive nyore kusanganisa, kupararira, uye kushandisa panzvimbo dzekuvaka.
   • CMC inoshanda senge viscosity modifier uye rheology control agent, ichipa yakatsetseka uye ine cream kuenderana kumusanganiswa wedhaka.
   • Izvi zvakavandudzwa kushanda zvinogonesa kunamira kuri nani uye kufukidzwa kwemayuniti emasoni, zvichikonzera mabhondi akasimba uye mamwe majoini edhaka akaenzana.
3. Enhanced Adhesion:
   • CMC inoshanda sebhainda uye inonamira mumatope maumbirwo, inosimudzira kunamatira pakati pesimende zvinhu uye aggregates.
   • Nekugadzira firimu rakatetepa pamusoro pezvimedu, CMC inowedzera iyo inopindirana yekubatana simba uye kubatana mukati medhaka matrix.
   • Kunamira uku kunoderedza njodzi yeku delamination, spalling, uye kusungirirwa kwematanho edhaka, kunyanya mumhepo kana pamusoro pekushandisa.
4. Kuderedza Kudonha uye Kudonha:
   • Kuwedzerwa kweCMC kunobatsira kudzivirira kudonha uye kudonha kwedhaka panguva yekushandiswa panzvimbo dzakamira kana dzakarerekera.
   • CMC inopa thixotropic zvivakwa kumusanganiswa wedhaka, zvichireva kuti inova isina viscous pasi pekuveura kushushikana (senge panguva yekusanganiswa kana kupararira) uye inodzokera kune yayo yekutanga viscosity kana yazorora.
   • Iyi thixotropic maitiro inodzivirira kuyerera kwakanyanya kana deformation yedhaka, kuchengetedza chimiro chayo uye kurongeka kwechimiro kusvika yagadzika uye yapora.
5. Kuwedzera Kubatana uye Kuchinjika:
   • CMC inokwidziridza kubatana uye kuchinjika kwedhaka, zvichikonzera kuvandudzwa kwekutsemuka uye kukanganisa kunyura zvivakwa.
   • Iko kubatanidzwa kweCMC kunovandudza homogeneity uye kuwirirana kwematope matrix, kuderedza mukana wekuparadzanisa kana kupatsanurwa kwezvikamu.
   • Izvi zvakawedzera kubatana uye kushanduka-shanduka zvinobvumira dhaka kuti rigadzirire kufamba kudiki uye kudedera muchivako chekuvaka, kuderedza njodzi yekutsemuka uye kukuvadzwa kwechimiro nekufamba kwenguva.
6. Inodzorwa Kuseta Nguva:
   • CMC inogona kubatsira kudzora nguva yekumisikidza yedhaka, ichikurudzira chiyero chainoomesa uye kuwana simba.
   • Nekudzoreredza kana kumhanyisa iyo hydration process ye simende zvinhu, CMC inobvumira kudzora zvirinani pamusoro penguva yekushanda uye kuseta maitiro edhaka.
   • Iyi inodzorwa nguva yekumisikidza inovimbisa yakakwana nguva yakavhurika yekushandisa dhaka uye kugadzirisa uku uchidzivirira kuseta nguva isati yakwana kana kunonoka zvakanyanya mumabasa ekuvaka.
7. Yakavandudzwa Kusimba uye Kuramba Kwemamiriro ekunze:
   • CMC inosimudzira kusimba uye kuramba kwemamiriro ekunze kwedhaka, ichipa dziviriro kubva mukunyorova ingress, kutonhora-kunyorova kutenderera, uye kuparara kwemakemikari.
   • Iyo yakagadziridzwa yekuchengetedza mvura uye yekunamatira zvivakwa zveCMC zvinobatsira mukudzivirira mvura zvirinani uye kuvharika kwezvivakwa zvemasoni, kuderedza njodzi yekukuvadzwa kwemvura uye efflorescence.
   • Pamusoro pezvo, CMC inobatsira kudzikisira mhedzisiro yekushanduka kwekushisa uye kuratidzwa kwezvakatipoteredza, kuwedzera hupenyu hwesevhisi uye kuita kwedhaka munzvimbo dzakasiyana dzemamiriro ekunze.

Zvikumbiro zveCMC muMortar:

1. General Masonry Kuvaka:
   • CMC-inokwidziridzwa dhaka inoshandiswa zvakanyanya mukuvaka masonry, kusanganisira kuvaka zvidhinha, kuvharira, uye kugadzira matombo.
   • Inopa hukama hwepamusoro, kushanda, uye kusimba, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa mukugara, kutengeserana, uye maindasitiri ekuvaka mapurojekiti.
2. Kuisa Tile:

Mhedziso:

Sodium carboxymethyl cellulose (CMC) inoita basa rakakosha mukusimudzira zvivakwa uye kuita kwedhaka mumashandisirwo ekuvaka. Semumiriri wekuchengetedza mvura, binder, rheology modifier, uye adhesion kukurudzira, CMC inovandudza kushanda, kunamatira, kusimba, uye kuramba kwemamiriro ekunze kwedhaka, zvichikonzera kusimba, kusimba, uye kwenguva refu-yakareba masonry zvimiro. Nemabhenefiti ayo akasiyana uye mashandisirwo, CMC inoramba ichiwedzera yakakosha muindasitiri yekuvaka, ichibatsira mukufambisira mberi kwezvinhu zvekuvaka uye zvivakwa pasi rese.
