Iintswelo ze-tender ye-rateber ityhefu

Xa kungena kwihlabathi leI-Whouleale Rageber Petals, kulula ukuba ingoyiki ngeendlela zokukhetha kunye nezinto ekufuneka ziqwalaselwe. Uninzi lwabafikayo lucinga ukuba lunokufumana umboneleli we-bulkstst, kodwa kuninzi kakhulu ekudlaleni. Iimpazamo zinokukhokelela kwiimpazamo ezixabisayo, zenza ukuba kubaluleke kakhulu ukuqonde isigebenga.

Ukuqonda ukukhetha izinto

I-gesibe yerabha iza ngezinto ezahlukeneyo, nganye inezixhobo ezahlukeneyo. Awungekhe ukhethe nje nayiphi na impahla ngaphandle kokujonga iimfuno ezithile zesicelo. I-Nitrley kunye ne-EPDM (E-Ithone proplene Diene Monomer) ihlala isetyenziswa ngenxa yokomelela kwayo, kodwa basebenzela iinjongo ezahlukeneyo. I-nitrile ithanda ukumelana kweoyile, ngelixa i-EPDM igqwesa kwimozulu kunye nokunganyangeki kwe-ozone. Ngesinye isihlandlo, xa wayebhengeza i-odolo yeprojekthi yokwakha, umntu osebenza ngempazamo ukhethe izinto ezingahambelaniyo, ezikhokelela ekungaphumli ngaphambi kwexesha - ukongamela kakhulu
