Ezweni lokwakha, ukubaluleka kwama-joint sealant akunakuphikiswana ngakho. Lezi zinto zidlala indima ebalulekile ekuqinisekiseni ubuqotho besakhiwo kanye nobude besikhathi sezingxenye ezahlukene zokwakha, ikakhulukazi ama-concrete joint. Phakathi kwezinhlobo ezahlukene zama-joint sealant, ama-polyurethane sealant ayisinqumo esithandwayo ngenxa yokusebenza kwawo okuphezulu kanye nokuguquguquka kwawo.
Isakhiwo Se-Universal GP Construction Joint PU Adhesive Sealant
I-SV 811FC iyinhlanganisela yesakhi esisodwa, esezingeni lesibhamu, enamathelayo futhi evalayo enokuqina okuhlala njalo. Le nto enezinjongo ezimbili isekelwe ku-polyurethane sealant ekhethekile ephulukiswa umswakama.
Izici
1. Ukunamathela okuhle kakhulu kuzo zonke izinto ezisekelwe kusimende, izitini, izinto zobumba, ingilazi, izinsimbi, ukhuni, i-epoxy, i-polyester kanye ne-acrylic resin.
2. Izinga lokuphulukisa okusheshayo.
3. Ukumelana nesimo sezulu okuhle nokumelana namanzi.
4. Ayiboli. Ingapendwa ngamanzi, uwoyela, kanye nopende olusekelwe ngerabha.
(Kunconywa ukuhlolwa kokuqala).
5. Ukuqina okuphezulu.
6. Ingasetshenziswa emalungeni amelana nokuphazanyiswa
Ezingeni elikhulu, ama-joint sealant abalulekile ekuvimbeleni amanzi, umoya, nezinye izinto zemvelo ukuthi zingangeni ezikhaleni nasezihlangwini zezinto zokwakha. Lokhu kubaluleke kakhulu ezakhiweni zekhonkrithi, njengoba ukungena komswakama kungaholela ekugqwaleni kwensimbi, ekulimaleni kokuqandisa kanye nokuwohloka kwekhonkrithi iyonke. Ngokuvala kahle ama-joints, ama-polyurethane sealant ahlinzeka ngesithiyo esivikelayo esiza ekugcineni ukuqina kwesakhiwo nokuqina kwaso.
Ngokuqondile, kubalulekile ukuqonda izakhiwo ezihlukile ze-polyurethane joint sealants ezenza zibe zilungele ukuhlangana kwekhonkrithi. Ngokungafani ne-sealants yendabuko, i-polyurethane sealants iguquguquka kakhulu futhi iyakwazi ukuzivumelanisa nokunyakaza nokwanda kwezakhiwo zekhonkrithi. Lokhu kuguquguquka kubalulekile ezindaweni lapho izinguquko zokushisa kanye nokunyakaza kwesakhiwo kuvame khona, njengoba kuvimbela i-sealant ukuthi iqhekeke noma ilahlekelwe ukusebenza kwayo ngokuhamba kwesikhathi.
Ngaphezu kwalokho, ama-polyurethane sealant anamathela kahle kakhulu ezindaweni ezikhonkolo, okuqinisekisa isibopho esiqinile nesihlala isikhathi eside esivala kahle amalunga. Lesi sibopho sibalulekile ekugcineni ubuqotho be-sealant ngaphansi kwezimo ezahlukahlukene zemvelo kanye nokucindezeleka kwesakhiwo. Ngaphezu kwalokho, ama-polyurethane sealant amelana kakhulu nesimo sezulu, amakhemikhali, kanye nokuchayeka kwe-UV, okwenza afaneleke ukusetshenziswa kokwakhiwa kwangaphakathi nangaphandle.
Ezingosini zekhonkrithi, izivalo ze-polyurethane zinezakhiwo ezinhle kakhulu zokwamukela ukunyakaza kwamalunga okuguquguqukayo nokungaguquki. Lokhu kuzuzisa kakhulu ukusetshenziswa okufana nokuhlanganiswa kokunwebeka, lapho isivalo kumele sikwazi ukumelana nokunyakaza okukhulu ngaphandle kokuthinta izakhiwo zaso zokuvala. Ngokusebenzisa izivalo ze-polyurethane ezingosini zekhonkrithi, ochwepheshe bokwakha bangaqinisekisa ukuthi amalunga ahlala evalwe ngempumelelo ngenkathi enikeza ukuguquguquka okudingekayo ukuze kuhlangatshezwane nokunyakaza kwesakhiwo.
Ngamafuphi, ukusetshenziswa kwezisekelo ze-polyurethane ekwakhiweni, ikakhulukazi ezisondweni zekhonkrithi, kubalulekile ekuqinisekiseni ukuqina kwesikhathi eside nokusebenza kwezakhiwo zokwakha. Lezi zisekelo zihlinzeka ngesithiyo esithembekile emiphumeleni yomswakama, umoya, nezinye izici zemvelo ngenkathi zihambisana nokunyakaza okuguquguqukayo okukhona ezakhiweni zekhonkrithi. Ngokuqonda ukubaluleka kanye nezakhiwo ezihlukile zezisekelo ze-polyurethane, ochwepheshe bezokwakha bangenza izinqumo ezinolwazi ezikhulisa ikhwalithi kanye nobude bemisebenzi yabo.
