Rongorongo

Ka horahia e te ranunga tohatoha nga waahanga ma te whakarewa; ko te whakaranu marara ka pakaru te agglomerates, te whakaiti ranei i te rahi o te wahanga marara. He maha nga wa e hiahiatia ana e te whirihoranga mahanga-wiri nga mea e rua, engari me whai te toenga i te koha me te hanganga, kaua ki te hiahia mo te kutikuti teitei ake. Tuatahi te tautuhi i te raru, ka whakatauritea te kounga ranu i roto i nga rohe wera me te miihini o te raina.

Whiriwhiria he kaihoroi wiri mahanga koeo, he whakarara wiri wiri whakarara ranei ma te hanga PVC, e hiahiatia ana te matapihi whakangao me te whirihoranga miihini, kaua ko te tapanga ahuahanga anake. Whakatauritehia nga mahi mahi riterite, katahi ka tirohia te whakaputanga kua whakaaetia, te kounga o te hua, te whakamahi hiko me te hototahi miihini. Mo te raina o naianei, whakatauhia mena ka hiahia koe ki etahi waahanga whakakapi, he hoahoa miihini rereke ranei i mua i te tono korero.

Extruder tīwiri pitch ko te mokowā axial i waenganui rererangi pātata; Ko te arahi ko te anga whakamua axial o te helix kotahi i te hurihanga katoa. He rite tonu i runga i te wahanga kotahi-tīmatatanga, engari kaua i runga i ia tīwiri. Whiriwhiria he huringa arataki ma te whai paanga ki te whangai, te whakarewa me te tuku pehanga, kaua ki te whakaaro he nui ake te mokowhiti ka pai ake te whakaputanga.

Ko te hōhonutanga o te hongere tīwiri Extruder e whakaahua ana i te mokowā i waenga i te pakiaka tīwiri me te tohutoro o waho kua tautuhia. Ma te hongere hohonu ka nui ake te waahi, engari kaore e whakaputa aunoa i nga putanga pai ake ki te aukati mate. Kōwhirihia te kōtaha mā te whāngai, te rewa, me te mahi papu, me te rahi o te rahi, te rawa me te oko taurite.

Ko te tauwehenga L/D te hurihanga takai kotahi ko te roa o te mahi kua wehea e te diameter huri noa. Kōwhirihia ma te waahi e hiahiatia ana mo te whangai, te whakarewa, te ranu, te hau me te whanaketanga pehanga, kaua ma te kii he nui ake nga hua ka puta mai i te waa roa. Whakapumautia nga tohu ine me te hototahi miihini i mua i te whakatairite i nga korero.

​E whakaatu ana te ōwehenga kōpeketanga o te tīwiri i te whakahekenga o te rōrahi hongere mai i te whāngai ki te inenga; mo nga wiri tikanga he rite tonu te mata ki nga rohe e rua, ka kiia ko te hohonutanga hongere whangai ka wehea ki te ine i te hohonutanga hongere. Kōwhirihia me te hōhonutanga tūturu, te roa whakawhiti, te whāngai me te hoahoa oko, kaua mai i te ingoa polymer anake. Ehara i te mea he pai ake te owehenga teitei ake.
