Te whakataki me ngā āhuatanga o te hua
Ko te ware parafini, e mōhiotia ana ko te ware karaihe, he momo wairewa i roto i te penehīni, te waro disulfide, te xylene, te ether, te benzene, te chloroform, te waro tetrachloride, te naphtha me ētahi atu whakarewa kore-polar, kāore e wairewa i roto i te wai, te methanol me ētahi atu whakarewa polar.
whakamahi
Ko te paraffin mata e whakamahia nuitia ana i roto i te hanga i ngā mati, te papa muka me te kānawehi nā te mea he nui te hinu kei roto. I muri i te tāpiri i te tāpiringa polyolefin ki te paraffin, ka piki ake tōna ira rewa, ka piki ake tōna piri me tōna ngāwari, ā, he whānuitia te whakamahinga i roto i te hanga pepa takai ātete-makuku me te ātete-wai, te kāri, te paninga mata o ētahi kakahu me ngā rama.
Ka taea te whakarite i te pepa kua rumakina ki te ware piro me te mahi ātete wai pai o ngā momo pepa ware piro, ka taea te whakamahi i roto i te kai, te rongoā me ētahi atu tākai, te waikura whakarewa me te umanga tā; ina tāpirihia te ware piro ki te miro miro, ka taea te whakangawari, te maeneene me te ngāwari o te kakahu. Ka taea hoki te hanga ware piro hei hopi horoi, hei emulsifier, hei dispersant, hei plasticizer, hei hinu, me ētahi atu.
He whānuitia te whakamahinga o te parafini kua oti te whakapai me te parafini kua oti te whakapai, te nuinga hei wāhanga me ngā rauemi takai mō te kai, te rongoā ā-waha me ētahi taonga (pēnei i te pepa ware pi, ngā pene rākau, ngā kānara me te pepa waro), hei rauemi whakakakahu mō ngā ipu tunu, hei tiaki hua [3], hei whakamahana i ngā wāhanga hiko, me te whakapai ake i te ārai-pakeketanga me te ngāwari o te rapa [4]. Ka taea hoki te whakamahi mō te waikura hei whakaputa waikawa ngako hangai.
Hei momo rauemi rokiroki wera huna, he pai ngā painga o te paraffin, arā, he nui te wera huna o te whakawhiti āhuahanga, he iti te huringa rōrahi i te wā o te whakawhiti āhuahanga totoka-wai, he pai te pumau o te wera, kāore he āhuatanga whakamatao, he iti te utu me ētahi atu. Hei tāpiri, ko te whanaketanga o te rererangi, te rererangi, te hikohiko iti me te hangarau optoelectronics e hiahia ana kia nui te wera kua memeha i puta i te wā e whakahaerehia ana ngā wāhanga mana-nui ka taea anake te memeha i roto i te rohe whakamarara wera iti me te wā poto rawa, ko ngā rauemi huringa āhuahanga iti te ira rewa ka taea te tere te tae ki te ira rewa ki te whakataurite ki ngā rauemi huringa āhuahanga teitei te ira rewa, me te whakamahi katoa i te wera huna hei whakatutuki i te whakahaere pāmahana. Ko te wā urupare wera poto o te paraffin kua whakamahia whānuitia i roto i ngā momo mara pēnei i te rererangi, te rererangi, te hikohiko iti me ētahi atu pūnaha hangarau teitei me te penapena pūngao whare.

E whakaaetia ana te whakamahinga o te kapia huka taketake e te GB 2760-96, ko te rohenga he 50.0g/kg. E whakamahia ana hoki i tāwāhi mō te hanga pepa raihi piri, ko te inenga he 6g/kg. Hei tāpiri, he whānuitia hoki te whakamahinga i roto i ngā rauemi takai kai, pērā i te ātete makuku, te ātete piri me te ātete hinu. He pai mō te kapia ngaungau kai, te kapia mirumiru me te hinu koura rongoā me ētahi atu wāhanga, tae atu ki te kawe wera, te tango i te whakarewa, te pēhi papa, te whakakanapa me ētahi atu ware pi e pā tika ana ki te kai me te rongoā (i hangaia mai i ngā wāhanga ware pi o te hinu, te hinu kirikiri rānei mā te pēhi makariri me ētahi atu tikanga).
mōkihi me te kawe
B. Ka taea te whakamahi i tēnei hua, 25KG, 200KG, 1000KGBAERRLS.
C. Penapenahia kia hiri ki roto i te wāhi hauhautanga, maroke, me te hauhautanga. Me hiri rawa ngā ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me hiri pai tēnei hua i te wā e kawe ana kia kore ai e uru te makuku, te kawakore me te waikawa kaha, te ua me ētahi atu poke.
