Zvisiri-shrink grouting zvinhu zvakakosha mukuvaka kwekuzadza mapundu uye voids pasina yakakosha shanduko yevhoriyamu, kuve nechokwadi chekugadzikana kwechimiro uye kusimba. Chinhu chakakosha muzvinhu izvi Hydroxypropyl Methylcellulose (HPMC), cellulose ether derivative iyo inosimudzira maitiro egrout.
Kuchengetedzwa Kwemvura Kwakawedzerwa
Imwe yemabhenefiti ekutanga eHPMC mune zvisiri-shrink grouting zvinhu kugona kwayo kuvandudza zvakanyanya kuchengetwa kwemvura. HPMC inoumba firimu pamusoro pezvimedu zvesimende, izvo zvinobatsira kuderedza kubuda kwemvura. Iyi mvura yakachengetwa yakakosha kune iyo hydration process ye simenti, kuve nechokwadi yakakwana uye yakafanana hydration. Nekuchengetedza hunyoro hwemukati, HPMC inoderedza njodzi yekudonha uye kutsemuka, izvo zvinogona kukanganisa kutendeseka kwegrout. Uyezve, kuchengetedzwa kwemvura kwakagadziridzwa kunowedzera nguva yekushanda yegrout, zvichibvumira kushandiswa kuri nani uye kupedza.
Kuvandudzwa Kwekushanda
HPMC inosimudzira kushanda kwezvinhu zvisiri-kudonha grouting, zvichiita kuti zvive nyore kusanganisa, kuisa, uye chimiro. Yayo yakasiyana-siyana rheological properties inoshandura viscosity ye grout, ichipa musanganiswa unogadziriswa uye wakabatana. Iyi yakawedzera viscosity inobatsira mukugovera kwakafanana kwemasimende masimende uye mafirita, zvichitungamira kune homogenous uye yakatsetseka grout. Pamusoro pezvo, HPMC inoderedza kupatsanurwa uye kubuda ropa, kuve nechokwadi chekuti grout inochengetedza chimiro chakafanana mukati mekushandisa kwayo uye maitiro ekurapa. Kuvandudzwa kwekushanda kunoderedzawo kushanda nesimba uye kunowedzera kushanda kwegrout application.
Kuwedzera Kunamatira
Iwo adhesion zvimiro zveasina-shrink grouting zvinhu zvinowedzerwa zvakanyanya neHPMC. Izvi zvinonyanya kukosha mumashandisirwo apo grout inofanirwa kubatana kune akasiyana substrates senge kongiri, simbi, kana masonry. HPMC inovandudza kugona kwekunyorova kwegrout, kukurudzira zvirinani kusangana neiyo substrate uye kuwedzera chisungo chesimba. Kuwedzeredzwa kunamatira kunodzivirira kusungirirwa uye kunovimbisa kuti grout inoramba yakasimba munzvimbo, ichibatsira kugadzikana kwese uye kusimba kwekuvaka.
Yakaderedzwa Shrinkage uye Kutsemuka
Shrinkage uye kupaza inyaya dzakajairika mune zvechinyakare grouting zvinhu, izvo zvinogona kutungamira kune kusasimba kwechimiro uye kutadza. HPMC inoita basa rakakosha kudzikamisa matambudziko aya nekudzikamisa hydration maitiro uye kuchengetedza hunyoro. Nekudzora chiyero chemvura-simende uye kuderedza kurasikirwa kwemvura, HPMC inoderedza njodzi yekuderera panguva yekurapa chikamu. Uku kugadzikana kwakakosha pakuchengetedza kutendeseka kweiyo grout, kuve nechokwadi chekuti inozadza mavhodhi uye mapeji zvinobudirira pasina kukanganisa kana kuderera nekufamba kwenguva.
Yakavandudzwa Kusimba
Iko kubatanidzwa kweHPMC mune zvisiri-shrink grouting zvinhu zvinowedzera kusimba kwavo nekuvandudza kuramba kune zvakatipoteredza zvinhu zvakadai sekuchinja kwekushisa, kushanduka kwehunyoro, uye kuratidzwa kwemakemikari. HPMC inoumba firimu rinodzivirira mukati megrout matrix, iyo inoshanda sechipingamupinyi kurwisa zvinhu zvekunze. Iyi nhanho yekudzivirira inobatsira kudzivirira kupinda kwezvinhu zvinokuvadza, kuderedza njodzi yekuora uye kuora. Kuwedzerwa kusimba kunovimbisa kuti grout inochengetedza kushanda kwayo uye kutendeseka kwemaitiro kwenguva yakareba, kuderedza mari yekugadzirisa uye kuwedzera hupenyu hwekuvaka.
Hydroxypropyl Methylcellulose (HPMC) inopa akawanda mabhenefiti muzvinhu zvisiri-shrink grouting, zvichiita kuti ive yekuwedzera yakakosha mukuvaka kwemazuva ano. Kugona kwayo kukwidziridza kuchengetwa kwemvura, kunatsiridza kushanda, kuwedzera kunamatira, kuderedza shrinkage, uye kugadzirisa kusimba kunobatsira pakuita kwese uye kuvimbika kwegrouts. Nekugadzirisa zvinhu zvakajairika senge shrinkage uye kutsemuka, HPMC inova nechokwadi chekuti zvisiri-shrink grouting zvinhu zvinopa zvinogara kwenguva refu, zvakatsiga, uye zvinoshanda mhinduro dzekuzadza mapundu uye voids mune akasiyana mafomu ekuvaka. Sezvo zvinodiwa zvekuvaka zvichiramba zvichishanduka, basa reHPMC mukugadzirisa zvinhu zvekugadzira grouting richaramba rakakosha, richitsigira kuvandudzwa kwemaitiro ekuvaka akasimba uye akasimba.
