Isihloko Sokufundisa: Ukuhlukaniswa Nokwabelana Kwamakethe Kwamafutha Okupholisa

I-Base oil ye-refrigeration oil iyimathiriyeli eyinhloko ethinta ukusebenza kwayo. Okwamanje, emakethe ye-refrigeration yomhlaba, ama-base oils e-refrigeration oil ahlukaniswe ngama-4, ngamaphesenti abo emakethe nezici zabo ezilandelayo: 1. I-Mineral Oil: Iphakathi nendawo ingama-65% emakethe, futhi iyona ebanzi kakhulu esetshenziswa njengama-base oils e-refrigeration oil okwamanje. Ihlanzwa kusuka ekudlulisweni kwe-petroleum, inenani eliphansi, ifanele ama-refrigerants angapheli, futhi ingahlangabezana nezidingo zama-compressors e-refrigeration ajwayelekile anemithwalo ephakathi nendawo kanye ne-low 2. I-Polyalphaolefin (PAO): Iphakathi nendawo ingama-22% emakethe. Njengoba i-base oil eyenziwe, inezinga elingcono lokuhamba kwe-low-temperature kanye nokuzinza kwe-high-temperature uma kuqhathaniswa ne-mineral oil. Ifanele ama-refrigerants angapheli/aphansi kancane futhi ivamise ukusetshenziswa kuma-compressors e-refrigeration anemithwalo ephezulu 3. I-Ester Oil (ikakhulukazi i-POE polyester): Iphakathi nendawo ingama-10% emakethe. Iyi-base oil eyenziwe, enokuhlangana okuhle kakhulu nama-refrigerants aphelele afana ne-R32 ne-R410A, futhi ivamise ukusetshenziswa ezinhlelweni ze-refrigeration zokuguqulwa kwemvamisa nezokugcina imvelo 4. Izinhlobo Ezinye (njenge-PVE ether oil): Iphakathi nendawo ingama-3% emakethe. Le ndlela ye-base oil inezici ezihlanganisiwe ezinamandla kakhulu, inokuhamba okuhle kwe-low-temperature kanye nokuzinza kwe-hydrolysis, kodwa inani layo liphakeme, futhi ivamise ukusetshenziswa ezimeni ezikhethekile zokusebenza ze-refrigeration ezine-high temperature noma i-ultra-low temperature. Isifinyezo Sokufundisa Uhlanga lwezi-4 lwezinhlobo zama-base oils lukhombisa nezidingo zamanje zezimboni ze-refrigeration: uhlanga oluphezulu lwe-mineral oil lukhombisa ukuthandwa kwezimo ze-refrigeration ezijwayelekile, kanti uhlanga lwe-base oils ezakhiwe lukhula unyaka nonyaka, okukhombisa ukuthi izidingo zezimboni ze-refrigeration ezilungele imvelo nezimfuno eziphezulu zikhula.
