Kwihlabathi lokwakha, ukubaluleka kwezixhobo zokuvala iintambo ezidibeneyo akunakugxininiswa kakhulu. Ezi zinto zidlala indima ebalulekileyo ekuqinisekiseni ukuthembeka kwesakhiwo kunye nobude bexesha lezinto ezahlukeneyo zokwakha, ingakumbi izixhobo zokuvala iintambo ezidityanisiweyo. Phakathi kweentlobo ezahlukeneyo zezixhobo zokuvala iintambo ezidityanisiweyo, izixhobo zokuvala iintambo ezidityanisiweyo ze-polyurethane zikhethwa kakhulu ngenxa yokusebenza kwazo okuphezulu kunye nokuguquguquka kwazo.
Uyilo lweNdawo yonke yeGP Construction Joint PU Adhesive Sealant
I-SV 811FC yinxalenye enye, yodidi lwesibhamu, yokuncamathelisa kunye nokutywina enokuqina okungapheliyo. Le nto inezinto ezimbini isekelwe kwi-polyurethane sealant ekhethekileyo eyomelezwa kumswakama.
Iimbonakalo
1. Ukunamathela okugqwesileyo kuzo zonke izinto ezisekwe kwisamente, izitena, iiseramikhi, iglasi, iintsimbi, umthi, i-epoxy, i-polyester kunye ne-acrylic resin.
2.Isantya sokuphiliswa esikhawulezayo.
3.Imozulu entle kunye nokumelana namanzi.
4. Ayibolisi. Ingapeyintwa ngamanzi, ioyile, kunye neepeyinti ezenziwe ngerabha.
(Kucetyiswa uvavanyo lokuqala).
5.Ukuqina okuphezulu.
6.Ingasetyenziswa kwiindawo ezichasene nokuxinana
Kwinqanaba elikhulu, izinto zokuvala ii-joint sealants zibalulekile ekuthinteleni amanzi, umoya, kunye nezinye izinto ezingqongileyo ukuba zingangeni kwizikhewu nakwiindawo ezidityanisiweyo zezinto zokwakha. Oku kubaluleke kakhulu kwizakhiwo zekhonkrithi, njengoko ukungena komswakama kunokukhokelela ekuboleni kwentsimbi, umonakalo wokuqandisa nokunyibilika komkhenkce kunye nokuwohloka kwekhonkrithi iyonke. Ngokuvala ii-joints ngempumelelo, izinto zokuvala ii-polyurethane zibonelela ngomqobo wokukhusela onceda ukugcina uzinzo lwesakhiwo kunye nokuqina kwaso.
Ngokukodwa, kubalulekile ukuqonda iimpawu ezikhethekileyo ze-polyurethane joint sealants ezenza ukuba zilungele ii-concrete joints. Ngokungafaniyo ne-polyurethane sealants zemveli, i-polyurethane sealants ziguquguquka kakhulu kwaye ziyakwazi ukuziqhelanisa nokuhamba kunye nokwandiswa kwezakhiwo ze-concrete. Oku kuguquguquka kubaluleke kakhulu kwiindawo apho utshintsho lobushushu kunye nokuhamba kwesakhiwo kuxhaphakile, njengoko kuthintela i-sealant ukuba ingaqhekeki okanye ilahlekelwe kukusebenza kwayo ngokuhamba kwexesha.
Ukongeza, izitywini ze-polyurethane zinamathela kakuhle kwiindawo zekhonkrithi, ziqinisekisa ukubopha okuqinileyo nokuhlala ixesha elide okuvala kakuhle amalungu. Olu kubopha lubalulekile ekugcineni ukuthembeka kwesitywini phantsi kweemeko ezahlukeneyo zendalo kunye noxinzelelo lwesakhiwo. Ukongeza, izitywini ze-polyurethane zinokumelana okukhulu nemozulu, iikhemikhali, kunye nokuvezwa yi-UV, nto leyo eyenza ukuba zifaneleke kwizicelo zokwakha zangaphakathi nangaphandle.
Kwizihlanganisi zekhonkrithi, izitywini ze-polyurethane zineempawu ezintle kakhulu zokwamkela iintshukumo zamalungu eziguquguqukayo nezinganyakaziyo. Oku kuluncedo ngakumbi kwizicelo ezifana nezihlanganisi zokwandisa, apho isitywini kufuneka sikwazi ukumelana nentshukumo enkulu ngaphandle kokuchaphazela iimpawu zaso zokutywina. Ngokusebenzisa izitywini ze-polyurethane kwizihlanganisi zekhonkrithi, iingcali zokwakha zinokuqinisekisa ukuba izihlanganisi zihlala zitywinwe ngokufanelekileyo ngelixa zibonelela ngokuguquguquka okufunekayo ukuze kuhlangatyezwane nentshukumo yesakhiwo.
Ngamafutshane, ukusetyenziswa kwezitywini ze-polyurethane ekwakhiweni, ingakumbi kwiindawo zokudibanisa zekhonkrithi, kubalulekile ukuqinisekisa ukuqina nokusebenza kwezakhiwo zokwakha ixesha elide. Ezi zitywini zibonelela ngomqobo othembekileyo kwimiphumo yokufuma, umoya, kunye nezinye izinto ezingqongileyo ngelixa zilungelelanisa iintshukumo eziguquguqukayo ezikwizakhiwo zekhonkrithi. Ngokuqonda ukubaluleka kunye neempawu ezizodwa zezitywini ze-polyurethane, iingcali zokwakha zinokwenza izigqibo ezinolwazi ezikhulisa umgangatho kunye nobude bemisebenzi yazo.
