Siyaqonda ukuba ulwelo lokusika luneempawu ezibalulekileyo ezifana nokupholisa, ukuthambisa, ukuthintela umhlwa, ukucoca, njl. Ezinye izongezo zibonelela nge-lubrication, ezinye zithintela ukugqwala, ngelixa ezinye zineempembelelo ze-bactericidal kunye ne-inhibitory. Ezinye izongezo ziluncedo ekupheliseni amagwebu, nto leyo eyimfuneko ukunqanda isixhobo sakho somatshini ekubeni sihlambe iqamza yonke imihla. Kukho nezinye izongezo, kodwa andizukwazisa apha ngabanye.
Ngelishwa, nangona ezi zongezo zingentla zibaluleke kakhulu, uninzi lwazo zikwinqanaba le-oyile kwaye zifuna ukucaphuka okungcono. Ezinye azihambelani, kwaye ezinye azinyibiliki emanzini. Ulwelo olusanda kuthengwa lokusika lulwelo olugxininisiweyo kwaye kufuneka luxutywe namanzi ngaphambi kokusetyenziswa.
Sifuna ukwazisa ezinye izongezo eziyimfuneko kwi-emulsion-type concentrates ukuze i-emulsify ngamanzi kwi-stable cutting fluid. Ngaphandle kwezi zongezo, iipropathi zolwelo lokusika ziya kuncitshiswa zibe ngamafu. Ezi zongezo zibizwa ngokuba “zi-emulsifiers”. Umsebenzi wabo kukwenza izithako ezinganyibilikiyo emanzini okanye enye kwenye “ixubene,” kufana nobisi. Oku kubangela ukusasazwa okulinganayo kunye nozinzo lwezongezo ezahlukeneyo kulwelo lokusika, ukwenza ulwelo lokusika olunokuthi luhlanjululwe ngokungenasizathu ngokwemfuno.
Ngoku makhe sithethe malunga neoyile yesikhokelo somatshini kaloliwe. I-oyile yesikhokelo kufuneka ibe nokusebenza kakuhle kokuthambisa, ukusebenza okuchasene nomhlwa, kunye nokusebenza okuchasene nokunxiba (oko kukuthi, ukukwazi kwefilimu yeoli yokuthambisa ukuze imelane nemithwalo enzima ngaphandle kokucudiswa komile kwaye kutyunyuzwe). Enye into ebalulekileyo kukusebenza kwe-anti-emulsification. Siyazi ukuba ulwelo lokusika luqulethe i-emulsifiers ukuze i-emulsifying izithako ezahlukeneyo, kodwa i-oyile yesikhokelo sikaloliwe kufuneka ibe neempawu ezichasayo zokuthintela ukunyuswa kwe-emulsification.
Siza kuxoxa ngemiba emibini namhlanje: i-emulsification kunye ne-anti-emulsification. Xa ukusika i-fluid kunye ne-oyile yesikhokelo sikaloliwe idibana, i-emulsifier kwi-cutting fluid idibanisa kunye nezithako ezisebenzayo kwi-oyile yesikhokelo, ekhokelela ekubeni umzila wesikhokelo ushiywe ungakhuselekanga, ungaxutywanga kwaye ulungele ukugqwala. Ukuthintela oku, kubalulekile ukuthatha amanyathelo afanelekileyo. Kuyafaneleka ukuba uqaphele ukuba i-emulsifier kumanzi okusika ayichaphazeli nje kuphela i-oyile yesikhokelo kodwa kunye nezinye ioyile kwisixhobo somatshini, njengeoyile ye-hydraulic kunye nendawo epeyintiweyo. Ukusetyenziswa kwe-emulsifiers kunokubangela ukuguga, umhlwa, ukulahleka kokuchaneka, kunye nomonakalo kwizixhobo ezininzi zoomatshini.
