Pakati pesimba rehupfu hwetalc padhaka rekuvaka ndipo pane kugona kwayo kukuru kwekuwedzera kushanda zvakanaka, chinhu chakakosha chinokanganisa zvakananga nyore uye kushanda zvakanaka kwemaitiro ekuvaka. Kana zvabatanidzwa mumusanganiswa wedhaka, zvidimbu zvidiki-diki zvetalc powder, zvinowanzova nehukuru kubva pa1 kusvika ku10 micrometer, zvinoshanda semafuta madiki. Zvikamu izvi zvinopindirana pakati pezvidimbu zvikuru zvejecha nesimende, zvichideredza kukweshana kunoitika panguva yekusanganisa nekushandisa.

Kuderedzwa kwekukweshana kune simba guru pahunhu hwe rheological hwe mortar. Mortar yakasanganiswa ne talc powder inoratidza kuyerera kwakawedzerwa, zvichiita kuti ifambe zviri nyore mukati me formwork kana kutenderedza zvinhu zvinosimbisa. Kuwedzera uku kuyerera kunobatsira zvikuru mumamiriro ezvinhu akaoma ekuvaka, akadai sekuumbwa kwezvinhu zvakaoma kana kuzadza mipata midiki. Pamusoro pezvo, talc powder inovandudza plasticity yemortar, zvichiita kuti iumbwe uye iumbwe nemazvo. Hunhu uhwu hunokosha mukushandiswa uko nzvimbo dzakatsetseka uye dzakafanana dzinodiwa, senge pakupurasita kana kuisa mafinishe ekushongedza.

Zvinobatsira pakuvandudza mashandiro zvakanaka zvikuru. Vashandi vekuvaka vanowana kudzikira kukuru mukushanda nesimba kunodiwa pakusanganisa, kutakura, uye kuisa dhaka. Izvi hazvingowedzere kubudirira kwavo chete asi zvinoderedzawo njodzi yekukuvara kunokonzerwa nekuneta. Mumapurojekiti makuru ekuvaka, uko nguva iri chinhu chakakosha, kushandiswa kwehupfu hwetalc kunogona kutungamira mukuchengetedza nguva yakawanda, kukurumidzisa nguva yepurojekiti uye kuderedza mari yese. Semuenzaniso, mupurojekiti yekuvaka yakakwirira, kuwedzera kushanda kwedhaka rakagadziridzwa talc kunogona kurerutsa maitiro ekuvaka zvidhinha, zvichibvumira vemason kuisa zvidhinha zvakawanda paawa nekunyatsorongeka.

Kuchengetwa kwemvura chinhu chakakosha chedhaka rekuvaka, sezvo richikanganisa zvakananga maitiro ekunyorovesa simende uye kugara kwenguva refu kwechinhu chacho. Hupfu hwetalc hunoita basa rakakosha mukuwedzera kuchengetwa kwemvura nekugadzira network inodzivirira yakakomberedza mamorekuru emvura mukati medhaka. Maumbirwo elamellar ezvidimbu zvetalc anogadzira chipingamupinyi chinononotsa kubuda kwemvura, zvichidzivirira kuoma nguva isati yakwana uye zvichiita kuti dhaka rirambe richishanda kwenguva yakareba.

Hwindo iri rekushanda kwenguva refu rinopa vashandi vekuvaka mukana wekushanda zviri nyore. Vane nguva yakawanda yekugadzirisa nzvimbo yezvidhinha kana mataira, kugadzirisa zvikanganiso, uye kuona kuti dhaka rakarongeka zvakanaka risati raiswa. Pamusoro pekuvandudza mhando yebasa rapera, kuchengetedza huwandu hwemvura yakakwana panguva yekunyorovesa kwakakosha pakugadzira simba rakazara redhaka. Kunyorovesa simende inyaya yakaoma yemakemikari inoda huwandu hwakati hwemvura kuti ienderere mberi nemazvo. Kusakwana kwemvura kunogona kukonzera dhaka risina kusimba uye rine maburi, zvichikonzera dhaka risina simba uye rinobuda nepakati rine simba shoma rekudzvanya uye kugara kwenguva refu.

Hunhu hwekuchengetedza mvura hwehupfu hwetalc hunonyanya kubatsira munzvimbo dzinopisa uye dzakaoma, uko kupwa kwemvura nekukurumidza kunogona kukonzera matambudziko makuru pakushanda kwehupfu hwetalc. Munzvimbo dzakadaro, kushandiswa kwehupfu hwetalc kunogona kubatsira kudzivirira hupfu hwetalc kuti husaome nekukurumidza, zvichiita kuti hurambe huchishanda uye hune simba. Uyezve, nekuderedza njodzi yekuoma nguva isati yakwana, hupfu hwetalc hunobatsira kuderedza kuitika kwezvikanganiso pamusoro, zvakaita sekutsemuka nekukweva, izvo zvinogona kukanganisa runako uye kusimba kwechimiro chechivakwa chapera.

Kupwanyika kwevhu panguva yekuomesa inyaya yakajairika inogona kukanganisa kunaka kwechivako uye chitarisiko chacho. Sezvo vhudzi racho richirasikirwa nehunyoro, rinopwanyika, uye kana vhudzi racho rikasadzorwa zvakanaka, rinogona kukonzera kupwanyika. Kupwanyika uku hakungodzikisi runako rwechivako chete asiwo kunopa nzira dzekupinda kwehunyoro, izvo zvinogona kukonzera matambudziko akasiyana-siyana, kusanganisira kukura kwevhudzi, ngura yekusimbisa, uye kuora kwechivako.

Upfu hwetalc hunopa mhinduro inoshanda padambudziko rekupwanyika kwemortar. Zvidimbu zvayo zvakanaka zvinoshanda sezvizadza, zvichigara munzvimbo dzisina chinhu uye mumaburi ari mukati memortar matrix. Nekuzadza nzvimbo idzi, talc powder inoderedza kuchinja kwehuwandu kunoitika panguva yekuomeswa, zvichideredza njodzi yekutsemuka. Maumbirwo elamellar ezvidimbu zvetalc anobatsirawo mukudzivirira kupwanyika, sezvo zvikamu zvinogona kutsvedza zvichipfuura, zvichigamuchira kushushikana kwemukati kunokonzerwa panguva yekuomeswa pasina kukonzera kukuvara kwemortar matrix.

Pamusoro pekudzivirira kutsemuka, kuderedza kupwanyika kunovandudzawo kugadzikana kwesimbi. Izvi zvakakosha zvikuru mukushandiswa uko kunodiwa kunyatsoenderana uye kurongeka kwakakodzera, senge pakuisa zvinhu zvakagadziriswa kare kana kuisa mataira makuru. Nekuchengetedza chimiro nehukuru hwakafanana, simbi yakawedzerwa talc inovimbisa kubatana kwakachengeteka uye kwakasimba pakati pezvikamu zvechivako, zvichivandudza mashandiro echivako chose.

Simba rekubatana pakati pedhaka nemidziyo yekuvaka, zvakaita sezvidhinha, kongiri, kana matombo, chinhu chikuru chinoratidza kusimba kwechivako. Chisungo chakasimba chakakosha pakufambisa mitoro zvinobudirira pakati pezvikamu uye kuona kuti chivako chinogona kutsungirira simba remhepo, kudengenyeka kwenyika, uye kushandiswa kwezuva nezuva. Hupfu hwetalc hunosimbisa simba rekubatana kuburikidza nenzira dzakasiyana-siyana, zvichiita kuti ive chinhu chinobatsira pakuvandudza mashandiro edhaka rinonamira.

Imwe yenzira huru dzinoshandiswa pakuvandudza simba re talc powder ndeyekuwedzera kubatana kwemuchina pakati pemota ne substrate. Zvidimbu zvidiki zve talc powder zvinopinda mumaburi uye zvisina kurongeka pamusoro pe substrate, zvichigadzira magadzirirwo akaomarara anowedzera kuramba kukweshana pakati pezvinhu zviviri izvi. Kubatana uku kwemuchina kunoshanda zvakanyanya mu substrate dzine maburi, dzakadai sezvidhinha nemabhuroko ekongiri, uko zvidimbu zve talc zvinogona kuzadza maburi uye kugadzira kubatana kwakachengeteka.

Pamusoro pekuvharika kwemuchina, upfu hwetalc hunovandudzawo hunhu hwekunyorovesa hwemortar. Nekuderedza kusimba kwepamusoro pemortar, upfu hwetalc hunobvumira kuti hupararire zvakaenzana uye hupinde zvakadzika mumaburi esubstrate. Izvi zvinoita kuti pave nekubatana kwakakwana uye kwepedyo pakati pemortar nesubstrate, zvichigadzira chisungo chakasimba chemakemikari. Hunhu hwekunyorovesa hwakawedzerwa hwemortar yakawedzerwa talc hunonyanya kubatsira mukushandiswa uko kunodiwa kunamira kwakanyanya, senge pakuisa cladding yekunze kana kugadzirisa zvivakwa zvekongiri zvakakuvara.

Kubatanidzwa kwekubatana kwemakanika uye hunhu huri nani hwekunyorovesa hunoita kuti simba remabhondi riwedzere zvakanyanya. Zvidzidzo zvakaratidza kuti mabhondi ane upfu hwetalc anogona kuratidza simba remabhondi rakakwira kusvika 30% zvichienzaniswa nemabhondi ekare. Simba iri remabhondi haringogadzirisi kugadzikana kwechivako chete asiwo rinowedzera kuramba kwaro kuzvinhu zvakatipoteredza, zvakaita sekunyungudika kwechando uye kurwiswa nemakemikari. Nekuda kweizvozvo, zvivakwa zvakavakwa nebhondi rakasimudzirwa netalc zvinogara kwenguva refu uye zvinoda kugadziriswa kushoma muhupenyu hwazvo, zvichipa kukosha kwenguva refu kune varidzi vezvivakwa nevagadziri.

Mukupedzisa, upfu hwetalc chinhu chinoshandiswa zvakasiyana-siyana uye chinoshanda mukusanganisa dhaka rekuvaka, zvichipa mabhenefiti akasiyana-siyana anowedzera kushanda, kugara kwenguva refu, uye runako rwezvinhu zvekuvaka. Kugona kwayo kuvandudza kushanda zvakanaka, kugadzirisa kuchengetedza mvura, kuderedza kuderera, uye kusimbisa chisungo pakati pedhaka nemidziyo inoita kuti ive chinhu chakakosha mumabasa ekuvaka emazuva ano. Sezvo indasitiri yekuvaka ichiramba ichichinja, kushandiswa kwehupfu hwetalc kunogona kuwedzera, sezvo ichipa mhinduro inogara kwenguva refu uye isingadhuri yekusangana nezvinodiwa zviri kukura zvezvinhu zvekuvaka zvinoshanda zvakanyanya. Ingave mumapurojekiti ekugara, ebhizinesi, kana ezvivakwa, hupfu hwetalc hwakazviratidza kuva chinhu chinokosha, huchibatsira mukugadzira zvivakwa zvakasimba, zvinogara kwenguva refu, uye zvinofadza runako.
