Crude parafini inonyanya kushandiswa mukugadzira machisi, fiberboard uye canvas nekuda kwekuwanda kwemafuta.Mushure meKUWEDZERA POLYOLEFIN ADDITIVE KUPARAFFIN, nzvimbo yaYO yekunyunguduka inowedzera, kunamira kwayo uye kuchinjika kunowedzera, uye inoshandiswa zvakanyanya mukugadzira mapepa ekuputira-unyoro uye asingapindi mvura, makadhibhodi, kupeta pamusoro pemamwe machira nemakenduru.
Iro bepa rakanyudzwa muparafini wakisi rinogona kugadzirirwa nekushanda kwakanaka kwemvura kwemapepa akasiyana-siyana, inogona kushandiswa muzvokudya, mishonga uye mamwe mapeji, simbi yesimbi uye kudhinda indasitiri;Kana parafini yaiswa pashinda yedonje, inogona kuita kuti machira acho apfave, atsvedzerere uye atete.Parafini inogona zvakare kugadzirwa detergent, emulsifier, dispersant, plasticizer, girisi, nezvimwe.
Parafini yakacheneswa zvizere uye semi-yakakwenenzverwa parafini inoshandiswa zvakanyanya, kunyanya sezvikamu uye zvekurongedza zvechikafu, mushonga wemuromo uye zvimwe zvinhu (senge bepa rewakisi, crayoni, makenduru uye carbon paper), semidziyo yekupfekedza yemidziyo yekubikira, kuchengetedza michero. [3], yekuvharisa zvinhu zvemagetsi, uye yekuvandudza anti-kuchembera uye kuchinjika kwerabha [4].Inogona zvakare kushandiswa kune oxidation kugadzira synthetic fatty acids.
Semhando yeyakavimbika kupisa kwesimba rekuchengetedza zvinhu, parafini ine zvakanakira hombe yakadzika kupisa kwechikamu chekuchinja, vhoriyamu diki shanduko panguva yakasimba-yemvura chikamu shanduko, yakanaka yekupisa kugadzikana, hapana undercooling chiitiko, yakaderera mutengo uye zvichingodaro.Pamusoro pezvo, kuvandudzwa kweaviation, aerospace, microelectronics uye optoelectronics tekinoroji inowanzoda kuti huwandu hukuru hwekupisa hunoburitswa panguva yekushanda kwezvikamu zvine simba repamusoro-soro hunogona kungobviswa munzvimbo shoma yekupisa kupisa uye nguva pfupi kwazvo, nepo yakaderera. melting point phase shanduko zvinhu zvinogona kukurumidza kusvika pakunyungudika zvichienzaniswa nepamusoro melting point phase shanduko zvinhu, uye shandisa zvizere kupisa kwakadzika kuti uwane tembiricha kutonga.Iyo ipfupi yekupisa yekupindura nguva yeparafini yakashandiswa zvakanyanya munzvimbo dzakasiyana siyana dzakadai sendege, aerospace, microelectronics uye mamwe masisitimu epamusoro-soro pamwe nekuchengetedza simba redzimba.[5]
GB 2760-96 inobvumira kushandiswa kwegamu shuga base agent, muganho ndeye 50.0g/kg.Kune dzimwe nyika zvakare inoshandiswa kugadzira mapepa emupunga anonamira, iyo dosage ye6g/kg.Uye zvakare, inoshandiswa zvakanyanya mumidziyo yekurongedza chikafu, senge mwando-uchapupu, anti-kunamatira uye mafuta-uchapupu.Inokodzera chikafu chekucheka chingamu, bubblegum uye mushonga mafuta akanaka egoridhe uye zvimwe zvikamu pamwe nekutakura kupisa, kudhiza, kudzvanya piritsi, kupukuta uye imwe wakisi yakanangana nechikafu uye mushonga (yakagadzirwa kubva kune waxy zvikamu zvemafuta kana shale mafuta. kudzvanya kutonhora nedzimwe nzira).

C. Chengetedza chakavharwa munzvimbo inotonhorera, yakaoma uye inofefetera mukati memba.Midziyo inofanira kuvharwa zvakasimba mushure mekushandiswa kwega kwega isati yashandiswa.
D. Ichi chigadzirwa chinofanira kuiswa chisimbiso zvakanaka panguva yekufambisa kudzivirira unyoro, alkali yakasimba uye asidi, mvura uye zvimwe tsvina kubva pakusanganiswa.
