Patinoshandisa michina ine mabhesi esimbi, kuchengetedza mugwagwa ukuwo tichichengetedza kugona kwenzira dzesimbi kutakura mutoro, tinowanzo sarudza kuisa shangu dzerabha kana mapedhi erabha panjanji. Nhasi, tichasarudza zvichibva pane zvakagadzirwa nemapedhi erabha chete.
Parizvino, zvinhu zvinoshandiswa mumachira erabha zvinoshandiswa kugadzira mabhesi enzira pamusika zvinowanzo sanganisira rabha nepolyurethane. Saka chinhu chikuru chekusarudza pakati pezviviri izvi chiri nyore: mumamiriro ezvinhu akaoma ekushanda, tinovavarira kugara kwenguva refu, uye tinoda polyurethane; panzvimbo inotsvedza yekushanda, tinoda kudhonzwa kwakanyanya, tobva tasarudza rabha kutanga.
※ Kana uchitsvaga nguva yakareba yekushanda uye inodzivirira kupfekwa zvakanyanya: sarudza polyurethane (PU)
· Kusapera kwepolyurethane kunopfuura raba ka3 kusvika ku10, uye hupenyu hwayo hwekushanda hunogona kupetwa kaviri kusvika katatu kupfuura raba.
· Haigoni kubvaruka kana kucheka, ine simba guru rekutakura zvinhu, uye yakasimba zvakapetwa kaviri kupfuura rabha. Yakakodzera michina yekugadzira mill yemumugwagwa nemidziyo yekuchera migodhi mumamiriro ekushanda akaomarara.
· Haina mafuta uye hainyungudike, haikurumidzi kuchembera kana kutsemuka, uye ine tembiricha yakakura yekushanda (-30°C kusvika 80°C).
※Kana nzvimbo yekushandira ichitsvedza kana kuti panodiwa dziviriro yemugwagwa: sarudza rabha
· Ine magadzirirwo akapfava uye inogona kubata zvakasimba pamawere akanyorova kana kuti ane mvura yakawanda.
· Ine kutwasuka kuri nani uye inogona kunyatsobata kuvhunduka kuti idzivirire sisitimu yechasi.
· Hazvikanganisi nzira yekufamba nayo uye zvakakodzera kune vanogadzira mapaipi vanoshanda pamugwagwa weasphalt, simende kana wezvidhinha.
※Kufunga nezvemutengo
· Mutengo wekutanga wekutenga: Rabha inowanzo dhura ne25% pane polyurethane.
· Mari yekushandisa yakakwana: Kunyangwe polyurethane ichishandiswa zvakanyanya pakutanga (30% - 50%), hupenyu hwayo hwekushanda hunogona kuderedza kuwanda kwekuitsiva uye nguva yekuidzima, uye nekufamba kwenguva, inogona kunge iine mutengo wakakwira.
Heino imwe nzira yekutora nzira pfupi: Unogona kutanga waongorora mamiriro ekushanda emidziyo.
· Pakushanda kwakaoma semigodhi, matuneri, materu, kana michina ine zvinhu zvinorema, polyurethane (PU) ndiyo sarudzo inosarudzwa.
· Kune michina inoda kubata nzvimbo dzinotsvedza dzakadai semigwagwa yakanyorova kana nzvimbo dzakadzika, kana kuti kune michina inoshanda pamugwagwa weasphalt senge mapavers, rabha ndiyo sarudzo inosarudzwa.
Muchidimbu, nekuona kana uchikoshesa hurefu hwebasa (kusarudza polyurethane) kana kuti kubata (kusarudza rabha), uye kufunga nezvekusarudza zvinhu zvezvikamu zvese zvechassis yese, unogona kuwana mhinduro inonyatsokodzera zvaunoda pakushanda!
