Isitywini segaraji yokupaka se-phezuluukuqina
Iigaraji zokupaka zihlala zinezakhiwo zekhonkrithi ezinemigangatho yekhonkrithi, ezibandakanya ulawulo kunye neendawo zokwahlukanisa ezifuna isitywini segaraji yokupaka esikhethekileyo. Ezi zitywini zidlala indima ebalulekileyo ekuqiniseni ixesha elide lezakhiwo zekhonkrithi, ngaloo ndlela ziphucula ukuqina kwegaraji iyonke.
Ngenxa yokuba iigaraji zokupaka zichatshazelwa kukutshintshatshintsha kobushushu, ukuchitheka kwepetroli kunye neekhemikhali ngamanye amaxesha, imithwalo enzima yoomatshini, kunye nokuhamba kwezithuthi, kubalulekile ukuba isitywini sesakhiwo sokupaka singachaphazeleki zezi zinto.
Iimpawu ezinqwenelekayo zesitywina sesakhiwo sokupaka
Iinkqubo zokutywina iigaraji zokupaka zenzelwe ukuvala iijoyinti kwikhonkrithi entsha nokulungisa ikhonkrithi eyonakeleyo okanye eqhekekileyo okanye i-asphalt. Zombini izicelo zifuna iimpawu ezithile, kuquka oku kulandelayo:
- Ukuguquguquka: Ukuvala nokuvala igaraji yokupaka kufuneka kuhlale kuguquguqukayo nokuba kuphantsi kotshintsho lobushushu ukuze kulungiselelwe ukuhamba kweendawo zekhonkrithi kunye namalungu ngaphandle kokuqhekeka okanye ukukrazuka.
- Ukumelana neekhemikhali: I-sealant kufuneka imelane namafutha, ioyile, kunye nezinye iikhemikhali ezichithekileyo, kunye nolwelo lwe-coolant, ityuwa yendlela, kunye nokuchitheka kwamafutha, ngelixa igcina amandla ayo kunye neempawu zokutywina.
- Umthamo wokuthwala umthwalo onzima: Isitywini akufuneki sichaphazeleke bubunzima bezithuthi ezipakiweyo, kwaye isitywini esinamandla sinokufuneka kwiindawo ezinezithuthi ezinzima ezifana neebhasi kunye neelori.
- Ukumelana nokurhawuzelelwa: Ngenxa yokuba kukho izithuthi ezininzi kwiindawo zokupaka, isitywini kufuneka sibonakalise ukumelana nokukrweleka okuphezulu ukuze sikwazi ukumelana nokuhamba rhoqo kwesithuthi.
3 Iintlobo zeenkqubo zokutywina igaraji yokupaka
Ukuze kuhlangatyezwane neemfuno ezahlukeneyo zeegaraji zokupaka, iintlobo ezahlukeneyo zezitywini zifanelekile. Ezi zilandelayo ziinkqubo ezintathu eziqhelekileyo zokutywina izakhiwo zokupaka:
1. I-PolysulfideEzi zitywini ziqinileyo zinika ukumelana okuphezulu neekhemikhali, ingakumbi amafutha kunye neoyile yemoto, kwaye zihlala zisetyenziswa kwizikhululo zepetroli. I-epoxy ingongezwa kwifomyula ukuze kubekho inkqubo eqinileyo neqinileyo xa kuyimfuneko.
2. I-Polyurethane: Eyaziwa ngokuguquguquka kwayo, izitywini ze-polyurethane zisetyenziswa kakhulu kwiinkqubo zokutywina izakhiwo zokupaka, nangona zisenokungabi nakumelana okuphezulu kweekhemikhali.
3. I-polymer ye-silane eguquliweyoEzi zitywini zibonelela ngokumelana neekhemikhali ezifana neenkqubo ze-silicone sealant eziqhelekileyo, kunye nokumelana okongezelelweyo nokukrala kunye noxinzelelo loomatshini, ngelixa zikwaguquguquka njenge-polyurethane.
Izinto ezichaphazela ukhetho lwesixhobo sokutywina isakhiwo sokupaka
Ukukhethwa kwesitywini segaraji yokupaka akuxhomekanga kuphela kuhlobo lwemveliso kunye neempawu zayo zomzimba, kodwa nakwizinto ezinokwenziwa. Xa ukhetha isitywini segaraji yokupaka, kubalulekile ukuqwalasela ixesha lokusetyenziswa kunye nexesha lokusilungisa, kunye nokuqina kwayo iyonke.
Indlela kunye nexesha lokufaka isicelo: Nokuba isitywini se-caulking segaraji yokupaka sifakwe kwikhonkrithi entsha okanye sisetyenziselwa ukulungiswa, kubalulekile ukuqwalasela ixesha elithathayo kunye nendlela yokufaka isicelo. Iindlela zokufaka izicelo ezintsonkothileyo kunye namaxesha amade okufaka isicelo zihlala zibangela ukuba kubekho ixesha elingakumbi lokungasebenzi.
Ixesha lokunyanga: Ingakumbi xa kulungiswa ikhonkrithi, kunokuba luncedo ukufaka nokulungisa isitywina sendawo yokupaka ngokukhawuleza kangangoko ukuze kuvulwe indawo yezithuthi emva nje kokufaka.
Imfuneko yokulungiswa: Kwikhonkrithi entsha, kuyacetyiswa ukuba ukhethe isitywini sesakhiwo sokupaka esihlala ixesha elide ngaphandle kokufuna ukulungiswa. Nangona ukusetyenziswa kunye namaxesha okunyanga ezi mveliso kungathatha ixesha elide, igaraji akunakwenzeka ukuba ingasebenzi emva kokwakhiwa. Ukulungiswa okuncinci kubalulekile nakwii-port sealants.
Xa ukhetha isitywini segaraji yokupaka, kufuneka kuqwalaselwe ixesha lokusetyenziswa kunye nexesha lokusila kunye nokuqina kwayo yonke into.
