I-1: Iimpawu zemibhobho yentsimbi yomthungo echanekileyo inenkqubo yokuvelisa elula, ukusebenza kakuhle kokuvelisa, ixabiso eliphantsi, uphuhliso olukhawulezayo, kunye nokuqina okulungileyo. Umgangatho weemveliso zemibhobho yentsimbi edityanisiweyo inokuthelekiswa nemibhobho yentsimbi engenamthungo, indlela yokuvelisa ilula, kwaye kulula ukutshintsha ukucaciswa kwemveliso kunye nemveliso. Iindleko ziphantsi kunezo zemibhobho yensimbi engenamthungo, ngoko ke ukusetyenziswa kwayo kuyanda unyaka nonyaka kwaye usetyenziso lwayo luba lukhulu ngakumbi.

2: Iimpawu ze-epoxy resin: Ifilimu yepeyinti emva kokuphiliswa yi-epoxy resin iqinile kwaye ayinamanzi, ayinayo ityhefu, kwaye ayingcolisi amanzi. Ukubambelela okuqinileyo, ukubambelela kakuhle phakathi kweefilimu zepeyinti. Ineempawu ezibalaseleyo zokuchasa umhlwa kunye nokumelana namanzi kwaye isebenzisa izixhobo ezibalaseleyo zokuchasa umhlwa ukuqinisekisa ukusebenza kwayo kokuchasana nomhlwa. Inamandla omatshini alungileyo, ifilimu yepeyinti eyomeleleyo, ukuxhathisa ukunxiba, kunye nokumelana nefuthe. Umxholo oqinileyo uphezulu kwaye ifilimu yokugqoka inzima. Ukunyanga kwiqondo lokushisa kwegumbi ukwenza ifilimu. Akukho mfuneko yezixhobo zokomisa ezinkulu. Iingubo ze-epoxy nazo aziyityhefu, ziqinisekisa ukhuseleko lokunikezelwa kwamanzi.
