Parafini isina kuchena inonyanya kushandiswa mukugadzira machisi, fiberboard uye canvas nekuda kwehuwandu hwakawanda hwemafuta ayo. Mushure mekuwedzera POLYOLEFIN ADDITIVE kuPARAFFIN, kunyunguduka kwayo kunowedzera, kunamira kwayo uye kuchinjika kwayo kunowedzera, uye inoshandiswa zvakanyanya mukugadzira bepa rekuputira rinodzivirira hunyoro uye mvura, kadhibhodhi, kufukidza pamusoro pemamwe machira nemakenduru.
Pepa rakanyikwa muparafini wakisi rinogona kugadzirwa nekushanda zvakanaka kwepepa rewakisi rakasiyana-siyana risingapindi mvura, rinogona kushandiswa mukudya, mishonga nezvimwe zvinhu zvekurongedza, ngura yesimbi uye indasitiri yekudhinda; Parafini painowedzerwa mushinda yedonje, inogona kuita kuti machira ave akapfava, akapfava uye anonamira. Parafini inogonawo kugadzirwa sipo, emulsifier, dispersant, plasticizer, grisi, nezvimwewo.
Parafini yakanyatsocheneswa uye parafini yakacheneswa zvishoma zvinoshandiswa zvakanyanya, kunyanya sezvinhu zvinoumba uye zvinhu zvekurongedza zvekudya, mishonga yemuromo nezvimwe zvinhu (zvakaita sepepa rewakisi, makrayoni, makenduru nepepa rekabhoni), sezvinhu zvekushongedza mumidziyo yekubikira, zvekuchengetedza michero [3], zvekudzivirira kupisa kwezvikamu zvemagetsi, uye zvekuvandudza kudzivirira kukwegura uye kuchinjika kwerabha [4]. Inogona zvakare kushandiswa mukugadzira oxidation kugadzira synthetic fatty acids.
Semhando yezvinhu zvinochengetedza simba rekupisa rakavanzika, parafini ine zvakanakira zvekupisa kukuru kwakavanzika kwekuchinja kwechikamu, kuchinja kudiki kwehuwandu panguva yekuchinja kwechikamu chakasimba-chemvura, kugadzikana kwakanaka kwekupisa, kusatonhora kwakanyanya, mutengo wakaderera nezvimwewo. Pamusoro pezvo, kuvandudzwa kwetekinoroji yendege, yendege, yemagetsi madiki uye ye optoelectronics kunowanzoda kuti huwandu hwakawanda hwekupisa kwakapararira hunogadzirwa panguva yekushanda kwezvikamu zvine simba guru hugone kungopararira munzvimbo shoma yekupisa uye kwenguva pfupi kwazvo, nepo zvinhu zvinoshandura nhanho diki zvinogona kusvika nekukurumidza pakunyunguduka zvichienzaniswa nezvinhu zvinoshandura nhanho diki, uye kushandisa zvizere kupisa kwakavanzika kuti uwane kudzora tembiricha. Nguva pfupi yekupindura kwekupisa yeparafini yakashandiswa zvakanyanya munzvimbo dzakasiyana-siyana dzakadai sendege, yendege, yemagetsi madiki nedzimwe nzira dzepamusoro-soro pamwe nekuchengetedza simba redzimba.

GB 2760-96 inobvumira kushandiswa kweshuga yegum, muganho wayo i50.0g/kg. Kunze kwenyika kunoshandiswawo pakugadzira mapepa emupunga anonamira, chiyero che6g/kg. Pamusoro pezvo, inoshandiswawo zvakanyanya muzvinhu zvekurongedza chikafu, zvakaita sekusanyorova, kusanamatira uye kusaomera mafuta. Yakakodzera chewing gum yechikafu, bubblegum uye medicine positive gold oil nezvimwe zvinhu pamwe nekupisa, kubvisa, kudzvanya mapiritsi, kupukuta uye mamwe wax anosangana zvakananga nechikafu nemushonga (akagadzirwa nemafuta ane wax kana shale oil nekudzvanya kunotonhora nedzimwe nzira).
