Te whakarōpūtanga o te whitiki whakamakuku maturuturu me te whakaurunga taputapu

Ngā whitiki whakamakuku maturuturu Ko te momo whakamakuku penapena wai tino whai hua i ēnei wā i ngā wāhi maroke me te kore wai, me te tere whakamahinga wai tae atu ki te 95 ōrau. He nui ake te penapena wai me te hua o te whakamakuku maturuturu i te whakamakuku pītiti, ā, ka taea te whakakotahi me te tono tongi hei whakapai ake i te whai huatanga o te tongi neke atu i te rua. Ka taea te whakamahi ki ngā rākau hua, huawhenua, hua hokohoko me te whakamakuku kati kōtuhi, ā, ka taea hoki te whakamahi mō te whakamakuku hua whenua i ngā wāhi maroke me te kore wai.

Kei te tere haere te whanaketanga o te rīpene whakamakuku maturuturu i roto i tā tātou hangarau whakamakuku maturuturu, nō reira he mea tino nui kia mōhio tātou ki te rīpene whakamakuku maturuturu.

Ko te rīpene whakamakuku maturuturu he whakamahi i ngā ngongo kirihou (te ara o te paipa whakamakuku maturuturu) ka tukuna te wai mā roto i te diameter o te 10mm te kāpia, te pane maturuturu rānei i te kōhao ki ngā pakiaka hua hei whakamakuku ā-rohe. Mā te kōhao putanga iti rawa ka uru ki roto i te pane maturuturu, ki te rīpene whakamakuku maturuturu rānei, ka maturuturu te wai i te maturuturunga, ka maturuturu mārire ki roto i te oneone e tata ana ki ngā pakiaka hua.

Ka wehea ngā rīpene whakamakuku maturuturu ki ngā rīpene whakamakuku maturuturu momo papaki, ngā ngongo whakamakuku maturuturu porotaka kua whakauruhia, ngā rīpene whakamakuku maturuturu momo roroa, me ngā rīpene whakamakuku maturuturu ara kikorangi.

Ngā āhuatanga o te rīpene whakamakuku maturuturu

● He pane maturuturu whakauru me tōna ake matapihi tātari, he pai te mahi ārai-aukati.

● Hoahoa rere pōrearea. He rite te whakamakuku.

● He pakari te hononga o te pane maturuturu me te paipa.

● He ngāwari te whakarerekētanga o te mokowā o te pane maturuturu, he whānui te whakamahinga.

Ko ngā taputapu hanga rīpene whakamakuku maturuturu te nuinga kotahi-wiri extruder (mīhini matua), ngā mīhini āwhina me ngā mīhini hurihuri. Ko te hanganga taketake o te mīhini whakaputa tīwiri kotahi ko: te taputapu tuku, te taputapu whāngai, te oko, te tīwiri, te pane me te mate me ētahi atu wāhanga e rima.

Pūrere tuku. Arā, ko te wāhanga taraiwa o te puku tīwiri, ko te tikanga he motuka, he tikanga whakaiti me ngā peera, me ētahi atu. I roto i te tukanga whakaputa pumau, me pupuri tonu te tere o te tīwiri i te taumata pumau hei ārai i ngā rerekētanga o te nui o te whakaputa, kia tutuki ai ngā whakaritenga whakaputa rerekē, me peia te tīwiri i ngā tere rerekē, ko te taputapu tuku o te kaihanga whakaputa te tikanga he tere rerekē kore-taahiraa.

Pūrere whakakī. Ko te tikanga, he pūwero whakakī kōniko te taputapu utu, me te uhi wai whakamatao huri noa i te tauranga utu hei tango i te wera mai i te oko pāmahana teitei ki te pūwero kia kore ai e wera te kirihou i roto i te tauranga utu me te piri, ka hua ake he utu kore taurite, he aukati rānei i te rere o te rauemi.

Ko te oko tētahi o ngā wāhanga matua o te extruder, e whakahaerehia ana ngā tukanga kirihou me te pēhanga i roto, ko te pēhanga i roto i te oko i te wā o te extrusion ka eke ki te 30 ~ 50Mpa, ko te pāmahana he 150 ~ 300℃, ā, he taputapu whakamahana me te whakamatao kua wehea i roto i te oko.

Ko te tīwiri te wāhanga matua o te extruder, nā te hurihanga o te tīwiri, ka neke te oko o te kirihou, ka whiwhi i te pēhanga me te wera, he pānga nui ngā tawhā āhua tīwiri o te tīwiri ki te mahi a te tīwiri, ko ngā tawhā matua o te tīwiri: te diameter o te tīwiri, te ōwehenga āhua, te ōwehenga kōpeketanga, me ētahi atu, ā, i tēnei wā, ko te diameter o te tīwiri extruder whakamakuku maturuturu ko te 40, 50mm te nuinga, me te ōwehenga āhua tata ki te 30: 1 ~ 40: 1.

Te pokepoke pane me te waha. Ko te pane te wāhanga nui i waenganui i te pokepoke pane me te oko, ā, ko te pokepoke pane te wāhanga hanga o te wāhanga hua, e mau ana ki te pane mā te whakamahi i ngā pūtu, i ētahi atu tikanga rānei. He nui te pānga o te tika o te pane me te pokepoke pane ki te putanga me te kounga o ngā hua, ā, ka whakatauhia te rahi i runga i te wheako mahi, i te mōhiotanga rheological rānei. Ko ngā mīhini āwhina, ko ngā mīhini āwhina he pokepoke hanga, he mīhini kukume me te pūnaha whakahaere tawhā. Ko tana mahi matua ko te hanga hua, te whakamatao hua, te whakahaere tawhā hua. Ko te mīhini takai, ko te nuinga mō te takai hua ki ngā hua kua oti, me te tuhi i te maha o ngā mita.

Ka panaia te kirihou mai i te hopper ki roto i te oko, ka panaia mārire te tīwiri ki te ahunga o te pane i te hurihanga, ka whakawhāitihia mārire te rauemi i roto i te wāhanga utu, ka uru te rauemi ki te wāhanga kōpeketanga, nā te pāpaku mārire o ngā miro, ā, nā te ātete o te mata matau-koki me te waha o te pokepokea ai, kia nui ai te pēhanga o te rauemi i roto i te hanganga.

Ka āta whakakīkītia te rauemi, i te wā kotahi i roto i te oko o te whakamahana o waho me te tīwiri o roto me te pakitara oko o te rauemi e whakaranu ana i te kutikuti i hangaia e te wera kutikuti, ka āta piki ake te pāmahana o te kirihou, tata ki te kotahi-tuatoru o te wāhanga kōpeketanga, ka tīmata ki te tae ki te pāmahana matotoru, ka nui ake te ahunga o te extrusion ki te pane, ka āta piki ake te nui o te rauemi rewa, ka āta whakaitihia te nui o te rauemi kore-rewa, tata ki te mutunga o te wāhanga kōpeketanga, ka rewa katoa te rauemi me te āhua matotoru, engari kāore te rewa i rewa.

Tata ki te mutunga o te wāhanga kōpeketanga, ka rewa katoa ngā rauemi, ka huri hei āhua matotoru, engari i tēnei wā, kāore tonu te pāmahana o ia pūwāhi i te tino ōrite. Whai muri i te wāhanga whakaōrite o te pānga whakaōrite, ka rewa te rauemi e te tīwiri ki roto i te pane i te pēhanga, te rahinga me te pāmahana kua whakaritea.

Ko te pokepokea waha i roto i te pane mīhini he wāhanga hanga, ka puta te rauemi mā roto i te pokepokea waha i roto i te pane mīhini hei hanga i tētahi wāhanga whakawhiti o te āhua me te rahi āhuahanga, kātahi ka puta mā roto i te wira hanga i runga i te korehau, ka whakamatao, ka tapahi, ā, ka puta te hua katoa.
