Ukukhetha isitywini esifanelekileyo solwandle ngo-2025 kuthetha ukuba kufuneka udibanise isitywini nezinto zenqanawa yakho kunye nendawo yokusetyenziswa. Izitywini zolwandle zePolyurethane zisebenza kakuhle kwimithi, ifiberglass, ialuminium, kunye nentsimbi kuba ziyamelana ne-UV, amanzi anetyuwa, kunye nemozulu. Iimpawu ezithembekileyo ezifana neJunbond Marine Sealant zibonelela ngeendlela eziphambili ezihlangabezana nemigangatho engqongqo yokusingqongileyo.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
- Tshatisa eyakhoisitywini saselwandlekwimpahla yesikhephe sakho nakwindawo ofuna ukuyivala ukuze ukhuseleke ngokuqinileyo nangokuhlala ixesha elide.
- Lungisa iindawo ngononophelo kwaye ulandele amanyathelo okufaka ukuze uphephe ukuvuza kwaye uqinisekise ukuba isitywini sisebenza kakuhle.
- Khethaiimpawu ezithembekileyo zesitywinakunye neentlobo ezifanela iimfuno zesikhephe sakho kunye nokusingqongileyo ukunciphisa ukugcinwa nokuphucula ukuqina.
Iimfuno zeSikhephe
Iintlobo zeenqanawa
Okokuqala kufuneka uchonge izinto zokwakha isikhephe sakho. Uninzi lwezikhephe luwela kolunye lwezi ndidi:
- Iinqanawa ezenziwe ngomthi okanye ngomthi
- Iinqanawa ze-fiberglass
- Iinqanawa zesinyithi (i-aluminium okanye intsimbi)
- Iinqanawa ezidityanisiweyo okanye zeplastiki
Uhlobo ngalunye luneemfuno ezizodwaizinto zokuvala zaselwandleUmzekelo, iinqanawa ezenziwe ngomthi zihlala zifuna izitywini eziguquguqukayo ukuze zikwazi ukusingatha ukuhamba komthi, ngelixa iinqanawa zefiberglass zixhamla kwizincamathelisi eziqinileyo zokudibanisa ihashe kunye needekhi. Iinqanawa zesinyithi zifuna iimveliso ezimelana nokugqwala. Ukukhethwa kwezitywini zaselwandle kuxhomekeke kakhulu kwizinto kunye nendawo ethile ofuna ukuyivala kunohlobo lwenqanawa iyonke.

Izicelo zeSealant yoLwandle
Uza kufumana izitywini zaselwandle ezisetyenziswa kwiindawo ezininzi kwisikhephe sakho. Ukusetyenziswa kwezitywini eziqhelekileyo kuquka:
- Ukutywina imithungo phakathi kweeplanga zedekhi okanye iiphaneli zehall
- Izixhobo zokulala ezifana nezikrufu kunye neebholiti ukuthintela ukuvuza
- Ukuvala ujikeleze iindawo zokungena, ii-portholes, kunye nezixhobo zokufaka i-through-hull
- Ukubopha ii-hulls kwizakhelo okanye kwizakhi zesakhiwo
Ezinye izitywini zaselwandle zisebenza kakuhle ngaphezulu okanye ngaphantsi komda wamanzi, ngoko ke soloko ujonga ilebhile yemveliso. Izitywini zepolyurethane, umzekelo, zincamathela ngokuqinileyo kwi-deck kunye ne-hull seams, ngelixa iintlobo ze-silicone zibalasele ekutywineni nasekuvaleni.
Izinto eziphathelele indalo
Ukuvezwa kwendalo kudlala indima enkulu ekusebenzeni nasekuphileni kwexesha lezinto ezitywinayo zaselwandle. Amanzi anetyuwa akhawulezisa ukugqwala kwaye anokuqhekeza imiqobo yokukhusela. Imisebe ye-UV evela elangeni ibangela ukufiphala kwaye yenze buthathaka into etywinayo ngokuhamba kwexesha. Ukutshintsha kobushushu kukhokelela ekwandeni nasekuncipheni, okunokubangela ukuqhekeka. Iinqanawa ezigcinwe kwiindawo eziselunxwemeni okanye ezisetyenziswa rhoqo kwiimeko ezinzima zifuna ukuphinda zisetyenziswe rhoqo, ngamanye amaxesha minyaka le. Kufuneka uhlale ulungelelanisa ukhetho lwakho lwento etywinayo nendawo elindelekileyo, nokuba isikhephe sakho sisebenza ngaphezulu okanye ngaphantsi komlambo, emanzini anetyuwa, okanye emanzini acocekileyo. Le ndlela ikunceda ugcine ukhuseleko oluhlala ixesha elide kwaye inciphisa iimfuno zokugcinwa.
Iintlobo zeMarine Sealant
Ukukhetha isitywini esifanelekileyo solwandle kuqala ngokuqonda iintlobo eziphambili zezitywini zolwandle ezifumanekayo ngo-2025. Uhlobo ngalunye luneempawu ezizodwa zesitywini solwandle kwaye lusebenza kakuhle kwizicelo ezithile.
