Kwinkqubo yokuvelisa izixhobo zesinyithi, ii-lubricants zizinto zokuthambisa ezisetyenziselwa ukunciphisa ukumelana nokungqubana kwee-frocchining pairs kunye nokucothisa ukuguguleka kwazo. Ii-lubricants zidlala indima efana nokupholisa, ukucoca, kunye nokuthintela ungcoliseko lwee-frocchining pairs. Nangona kunjalo, ukusetyenziswa kwee-lubricants kunokubangela amabala okugqwala, amabala amdaka namhlophe ongcoliseko kumphezulu wemveliso, okungenciphisi nje kuphela umgangatho wembonakalo yemveliso, kodwa kwandisa nobunzima bokucubungula okulandelayo, kwaye kuchaphazela nokusebenza kwemveliso.
Ukuze kuphuculwe umgangatho wemveliso kwaye kususwe amabala, kuyimfuneko ukufunda iinkqubo zokususa amafutha kumphezulu kunye nokucoca. Ulwakhiwo kunye neempawu zezithambiso zibaluleke kakhulu ekususeni amafutha kumphezulu kunye nokucoca. Amabala okungcola akhiwe kumphezulu wesinyithi anokwahlulwa abe ngamacandelo amathathu ngokwezinto ezibangela ungcoliseko:
(1)Ungcoliseko lweoyile – iigrisi kunye nee-fatty acids;
(2)Ungcoliseko olunyibilikayo emanzini – ii-asidi ze-organic kunye nee-asidi ezingaphiliyo;
(3) Ungcoliseko oluqinileyo – ii-oxides, amasuntswana, uthuli, njl.njl.
Iindlela eziqhelekileyo zokususa amafutha nokucoca imiphezulu yesinyithi zezi zilandelayo:
1. Indlela yokusula: Isetyenziswa ngesandla ngokubanzi, ifanelekile ukucoca iindawo ezintsonkothileyo kunye nemveliso encinci.
2. Indlela yokukhuhla: Ingacoca ukungcola okunamathele kancinci phezu komphezulu, okufanelekileyo kwimveliso encinci.
3. Indlela yokuqhola: Ingacoca izikali ze-oxide, izinto eziphilayo, iifilimu ze-alkali kunye namabala okugqwala kwiindawo zesinyithi, kodwa inefuthe lokukhuhla kumphezulu.
4. Indlela yokucoca isisombululo se-alkali: Isebenzisa isiphumo se-saponification sesisombululo se-alkali ukususa ungcoliseko olunokucocwa.
5. Indlela yokucoca i-organic solvent: Isebenzisa amandla okunyibilikisa i-organic solvents kwioyile kunye neegrisi ukususa ukungcola, ngexesha elifutshane lokucoca kwaye akukho mhlwa kwisinyithi, kodwa uninzi lwe-organic solvents luyingozi.
6. Indlela yokucoca nge-ultrasonic: Iguqula amandla esandi somthombo wokungcangcazela nge-ultrasonic abe kukungcangcazela koomatshini nge-transducer, ikhupha amaza e-ultrasonic kulwelo lokucoca olusetankini ngodonga lwetanki yokucoca, ukuze amaqamza amancinci kulwelo olusetankini akwazi ukugcina ukungcangcazela phantsi kwesenzo samaza esandi, nto leyo ebangela umonakalo wokudinwa kumaleko wothuli kwaye ngaloo ndlela iwukhuphe.
7. Indlela yokucoca i-emulsification, indlela yokucoca nge-electrolytic, njl.
Iindlela Eziqhelekileyo Zokusetyenziswa Kweearhente Zokucoca Imizi-mveliso Zokukhusela Okusingqongileyo
1. Ukucoca okanye ukubhobhoza ubushushu begumbi: Yandisa ixesha lokucoca ngokufanelekileyo, shukumisa kancinci isakhelo sokucoca ngexesha lokucoca ukuqinisekisa ukuba unxibelelwano olupheleleyo phakathi kwesixhobo somsebenzi kunye nolwelo lokucoca. Emva kokucoca, hlambulula kakuhle ngamanzi epompo uze womise.
2. Ukutshiza: Lungisa isixhobo sokucoca ngokwezinga elifunekayo, uze ubeke izinto eziza kucocwa kumatshini wokutshiza.
3. Ukufunxa ngobushushu: Fudumeza isixhobo sokucoca esilungiselelwe ngamanzi ngoxinzelelo oluthile ukuya kuthi ga kwi-70-80°C ngokwemeko yokwenyani. Emva kokucoca imizuzu emi-5-15 (ukushukumisa kakuhle isixhobo sokusebenza ngexesha lokucoca kunokufezekisa isiphumo esingcono sokucoca), hlambulula kakuhle ngamanzi epompo uze womise.
4. Ukusula ngesandla: Ngokubanzi, nciphisa isisombululo sokuqala ukuya kuthi ga kwi-10-20 (kuxhomekeke kwiimeko ezithile), uze usebenzise ilaphu elifakwe kwisixhobo sokucoca esixutyiweyo xa usula. Kungcono ukunxiba iiglavu xa usula. Xa kuthelekiswa nokucoca ngokuzenzekelayo ngumatshini wokucoca, ukusula ngesandla kufuna uxinzelelo oluphezulu lwesixhobo sokucoca.
5. Ukucoca nge-ultrasonic: Fudumeza i-arhente yokucoca exutyiweyo ukuya kuma-55-65°C usebenzisa umatshini we-ultrasonic, coca imizuzu emi-3 ukuya kweli-10, uze uhlambe kakuhle ngamanzi epompo uze womise.
