Imboni yokubeka phansi ichitha cishe amaRandi ayizigidi eziyizinkulungwane ezingu-2.4 ngonyaka ukulungisa ukwehluleka okuhlobene nomswakama. Noma kunjalo, amakhambi amaningi angabhekana kuphela nezimpawu zokwehluleka okuhlobene nomswakama, hhayi imbangela eyinhloko.
Isizathu esiyinhloko sokwehluleka phansi umswakama ophuma kukhonkolo. Nakuba imboni yezokwakha ibone umswakama ongaphezulu njengembangela yokuhluleka kwephansi, empeleni kuwuphawu lwenkinga ejulile. Ngokubhekana nalesi sibonakaliso ngaphandle kokubhekana nembangela, ababambiqhaza babhekana nengozi yokuqhubeka nokwehluleka kwephansi. Emashumini ambalwa eminyaka adlule, imboni yezokwakha yenze imizamo eminingi yokuxazulula le nkinga, kodwa yaba impumelelo encane. Izinga lamanje lokulungisa lokumboza i-slab nge-adhesive ekhethekile noma i-epoxy resin ixazulula kuphela inkinga yomswakama ongaphezulu futhi indiva imbangela eyinhloko yokungena kwekhonkrithi.
Ukuze uqonde lo mqondo ngokugcwele, kufanele uqale uqonde isayensi eyisisekelo yekhonkrithi ngokwayo. Ukhonkolo iyinhlanganisela eguquguqukayo yezingxenye ezihlanganayo zakhe inhlanganisela ye-catalytic. Lena indlela eyodwa yokusabela kwamakhemikhali elandelanayo eqala lapho amanzi engezwa ezithakweni ezomile. Ukusabela kwenzeka kancane kancane futhi kungashintshwa amathonya angaphandle (njengezimo zomkhathi nezindlela zokuqeda) nganoma yisiphi isikhathi enqubweni yokusabela. Ushintsho ngalunye lungaba nomthelela omubi, ongathathi hlangothi noma omuhle ekungeneni. Ukuze uvimbele lezi zimo ukuthi zingaphumeleli, ukusabela kwamakhemikhali okuyindlela eyodwa yokwelapha ukhonkolo kufanele kulawulwe. Imikhiqizo ekwazi ukulawula lokhu kusabela kwamakhemikhali, ithuthukise ukungeneka kukakhonkolo, futhi iqede ukugoqa phansi kanye nokuqhekeka okuhlobene nokwelapha.
Ngokusekelwe kulokhu okutholakele, i-MasterSpec ne-BSD SpecLink idale ukuhlukaniswa okusha eNgxenyeni 3, ekhonjwe njengokulapha nokuvala uphawu, enciphisa ukukhishwa komswakama, nokungena. Lesi sigaba esisha sesigaba sesi-3 singatholakala ku-MasterSpec isigaba 2.7 kanye ne-BSD SpecLink eku-inthanethi. Ukuze ufanelekele lesi sigaba, imikhiqizo kufanele ihlolwe ilabhorethri ezimele evela eceleni ngokuhambisana nezindlela zokuhlola ze-ASTM C39. Lesi sigaba akufanele siphanjaniswe nanoma iyiphi inhlanganisela yokunciphisa ukukhishwa komswakama okwakhiwa ifilimu, esethula imigqa yokubopha eyengeziwe futhi engahlangabezani namazinga aphezulu okusebenza okuhlukaniswa kwe-permeation.
Imikhiqizo yalesi sigaba esisha ayilandeli inqubo yokulungisa evamile. (Izindleko ezimaphakathi zangaphambilini okungenani bezingu-$4.50/square foot.) Esikhundleni salokho, ngokufaka isifutho esilula, lezi zinhlelo zingangena ukhonkolo, zinciphise i-capillary matrix, futhi zinciphise ukungena. Ukungeneka okuncishisiwe kuphazamisa indlela evumela umswakama, umswakama, kanye ne-alkalinity ukuthi ihanjiswe phezulu kwe-slab noma isendlalelo sokubopha. Ngokumane uqede ukwehluleka phansi ngokuphelele, kungakhathaliseki uhlobo lwephansi noma ukunamathela, lokhu kuqeda izindleko eziphakeme zokulungiswa okuhlobene nomswakama ngenxa yokuhluleka phansi.
Umkhiqizo owodwa kulesi sigaba esisha i-VC-5 ye-SINAK, elawula ukungeneka futhi iqede ukwehluleka phansi okubangelwa umswakama, umswakama, kanye ne-alkalinity ekhishwa ukhonkolo. I-VC-5 ihlinzeka ngokuvikeleka okuhlala njalo ngosuku lokubekwa kukakhonkolo, iqeda izindleko zokulungisa, nokufaka esikhundleni sokuphulukisa, ukuvala uphawu, nezinhlelo zokulawula umswakama. Ngaphansi kuka-1 USD/m². Uma kuqhathaniswa nezindleko zokulungisa ezijwayelekile, i-VC-5 ingonga ngaphezu kuka-78% wezindleko. Ngokuxhumanisa isabelomali seSigaba 3 kanye neSigaba 9, uhlelo luqeda izibopho ngokwenza ngcono ukuxhumana kwephrojekthi kanye nokuhlela okuyimpumelelo. Kuze kube manje, i-SIAK ukuphela kwenkampani esithuthukise ubuchwepheshe obudlula izindinganiso eziphakeme kakhulu zemboni kulo mkhakha.
Ukuze uthole ulwazi olwengeziwe mayelana nendlela yokuvimbela izinkinga zomswakama we-slab nokuqeda amaphutha okuchichima, sicela uvakashele ku-www.sinak.com.
Okuqukethwe okuxhasiwe yingxenye ekhokhelwayo ekhethekile lapho izinkampani zomkhakha zihlinzeka ngokuqukethwe okungekona okokuthengisa kwekhwalithi ephezulu, okunenjongo okuzungeze izihloko ezithakaselwa izethameli zamarekhodi ezakhiwo. Konke okuqukethwe okuxhasiwe kunikezwa izinkampani zokukhangisa. Unentshisekelo yokubamba iqhaza esigabeni sethu sokuqukethwe esixhasiwe? Sicela uthinte omele indawo yangakini.
