He maha ngā painga o te tāpiri i ngā pīrere karāhe tuwhera ki ngā hua rapa:
1. Te whakaiti i te taumaha
Ko ngā hua rapa hoki e anga atu ana ki te huarahi māmā, pakari, inā koa ko te whakamahinga pakeke o ngā kapu rapa piripiri moroiti, mai i te kiato tikanga o te 1.15g/cm³ pea, tāpirihia he 5-8 wāhanga o ngā piripiri moroiti, ka whakaitihia ki te 1.0g/cm³ (e mōhiotia whānuitia ana ko te "tere i runga i te wai"), he taumata motuhake o te kaha R&D o ngā kiritaki mā te tāpiri i ngā piripiri moroiti ka eke ki te kiato o te 0.9, tae atu rānei ki te 0.85g/cm³, ka tino whakaitihia te kiato o te rapa, ngā hu me te āhua ōrite i mua i te whakahekenga taumaha o te 20%. I tēnei wā, ko ētahi kiritaki me ētahi kaha R&D ka hanga i te kiato o te 0.9, tae atu rānei ki te 0.85g/cm³ mā te tāpiri i ngā piripiri moroiti, ka tino whakaitihia te kiato o te rapa, ā, ka heke te taumaha o ngā hu mā te 20% i raro i te āhua ōrite i mua.
2, Ārai wera
Nā te hanganga tuwhera o ngā pirepire karāhe tuwhera, ka iti te kawe wera o ngā pirepire, nā te mea he iti te kawe wera o te whakakī i tāpirihia ki te rauemi rapa, ka taea e ia te whai pānga pai ki te whakamahana wera, pērā i ngā papa whakamahana wera, ngā papa whakamahana wera me ētahi atu hua e whakamahia ana.
3, Te mimiti oro me te whakaiti haruru
Kei roto i ngā pirepire karāhe tuwhera he hau angiangi, ka ngoikore ngā ngaru oro i tēnei wāhanga, ā, i roto i tētahi nui o te tāpiritanga ka tino pai te pānga o te mimiti oro me te whakaiti i te haruru.
4, He pai te pumau o te taha
Ko te rauemi turanga o ngā piriti he karāhe, he iti te tauwehenga o te whakawhānui wera, he pai te pumau o ngā āhuatanga ina pāngia e te ru wera, ā, mā te tāpiri atu ki te rauemi rapa ka pai ake te pumau o ngā āhuatanga o te hua.
Ngā whakaaro mō te whakamahi i roto i te tukatuka:
1, ko ngā taputapu tukatuka hua rapa he mea hanga ki te para matotoru, ki te whakatuwhera, ki te extruder tīwiri kotahi, me ētahi atu. Nā te mea he rauemi karāhe ngā piripiri, nō ngā matūriki pakari te pakitara, ā, i raro i te mana kutikuti miihini ka pakaru tetahi wāhanga, ka ngaro te mahi ahurei o ngā piripiri i muri i te pakaru.
2, he rerekē ngā tauira me ngā tawhā e rite ana o ngā pīrere karāhe tuwhera, he mea tino nui te whiriwhiri i ngā hua pīrere tika kia rite ki ngā taputapu me ngā whakaritenga hua rerekē, e taunaki ana a St. Leite kia whakamahia te HL38, HL42, HL50, HS38, HS42 i roto i ngā hua rapa.
3, ina whakamahia i roto i te mīhini whakamahine, he rotor kei runga i te kutikuti rauemi rapa, kāore e taea te karo i ngā pirepire e te kaha kutikuti, nō reira, kia taea ai te whakaiti i te wā o ngā pirepire i roto i te whakamahine, me tāpiri te whakamahine mutunga kia taea ai te whakamarara ōrite i ngā pirepire i tāpirihia ki te whakamahine mō te 3-5 meneti; i roto i te mīhini whakamahine, he nui ake te pānga o te mokowā roera me te wā whakamahine o te kuru o ngā pirepire, me tūtohu kia neke atu i te 2mm te mokowā roera, kaua e roa rawa te wā whakamahine; He iti te kaha kutikuti whānui o te extruder tīwiri kotahi, he iti te pānga ki ngā pirepire iti, me whakanui ake te pāmahana extrusion mā te 5 ℃, kia whakaitihia te matotoru o te rauemi kia pai ake ai te hanga extrusion, kia whakaitihia te pakaru o ngā pirepire iti.
