Koinei te huarahi hei horoi i ngā taputapu whakaputa kirihou, e mōhio ana koe?

I ēnei rā, me ngā hangarau matatau, ehara te horoi i te extruder kirihou i te raruraru nui, engari me pēhea te horoite miihini whakaputa kirihouHe raruraru te mahi tika me te utu iti, me te kore e pakaru te tīwiri me te oko, ā, ka waiho hei raruraru mēnā ka hē te mahi, ka puta rānei he raruraru nui. I tēnei rā, me kōrero tātou mō te horoi tika i te extruder kirihou (te tīwiri me te oko te nuinga) hei painga mō te katoa.

01. Me pēhea te horoi tika i te tīwiri?

1) Kōwhiria te taputapu whakamahana tika

Ko te whakamahi i te ahi, i te ahi rānei hei tango i te kirihou e mau ana ki te tīwiri te tikanga tino noa, tino whai hua hoki mō ngā waeine tukatuka kirihou, engari kaua rawa e whakamahia te mura acetylene hei horoi i te tīwiri. Ka taea e te pāmahana o te mura acetylene te eke ki te 3000°C. Mā te horoi i te tīwiri ki te mura acetylene, ehara i te mea ka whakangaro noa i ngā āhuatanga whakarewa o te tīwiri, engari ka pā nui hoki ki te manawanui ā-pūkaha o te tīwiri.

Ki te huri te mura o te acetylene ki te kikorangi pumau i te wa e tunua ana tetahi wahi o te tīwiri, ko te tikanga kua rereke te hanganga whakarewa o tenei wahi o te tīwiri, ka heke te ātete kakahu o tenei wahi, tae atu ki te putanga mai o te paparanga ātete kakahu me te matihiko. Te tangohanga whakarewa. Hei tāpiri, ko te wera ā-rohe o te mura acetylene ka wera rawa tetahi taha o te tīwiri, ka piko ai te tīwiri. Ko te nuinga o ngā tīwiri he mea hanga ki te maitai 4140.HT me ngā manawanui tino piri, i roto i te 0.03mm.
Ko te tika o te tīwiri kei roto i te 0.01mm te nuinga. Ina tunua te tīwiri, ā, ka whakamataohia e te mura acetylene, he uaua ki te hoki ki tōna tika taketake. Tikanga tika me te whai hua: whakamahia he rama pupuhi hei horoi i te tīwiri i muri tonu i te whakamahinga. Nā te mea he wera kei te tīwiri i te wā e tukatukahia ana i tēnei wā, he ōrite tonu te tohatoha wera o te tīwiri.

2) Kōwhiria te kaihoroi tika

I ēnei rā, i te mea kua tino whanake te ōhanga taonga, he maha ngā momo horoi tīwiri (ngā rauemi horoi tīwiri) kei te mākete, he nui te utu, ā, he rerekē ngā pānga. Ko te whakamahi i ngā kaihoko horoi arumoni ka whakawhirinaki ki ngā kaihanga me ngā tikanga whakaputa rerekē; ka taea hoki e ngā umanga tukatuka kirihou te whakamahi i ngā kapia rerekē hei rauemi horoi tīwiri i runga i ā rātou ake tikanga whakaputa, ka taea ai te penapena moni nui mō te waeine.

3) Kōwhiria te tikanga horoi tika

Ko te taahiraa tuatahi ki te horoi i te tīwiri ko te whakaweto i te whakaurunga whāngai, arā, te kati i te putanga whāngai i raro i te hopper; kātahi ka whakaitihia te tere o te tīwiri ki te 15-25r/min, ka pupuri i tēnei tere kia mutu rā anō te rere o te rewa i mua o te matao kia. Me whakatakoto te pāmahana o ngā rohe wera katoa o te oko ki te 200°C. Ka tīmata te horoi ina tae te oko ki tēnei pāmahana.
I runga anō i te tukanga whakaputa (me tango pea te mate hei whakaiti i te tūponotanga o te pēhanga nui ki te pito o mua o te extruder), me mahi te horoi e te tangata kotahi: ka tirohia e te kaiwhakahaere te tere me te taipana o te tīwiri mai i te papa whakahaere, me te tirotiro anō hoki i te whakaputa kia kore ai e tino teitei te pēhanga o te pūnaha. I te wā katoa o te tukanga, me pupuri te tere o te tīwiri i roto i te 20r/min. Mō ngā tono mate pēhanga iti, kaua e tangohia te mate hei horoi i te tuatahi. Kati tonu te whakaputa, ka tangohia te pane o te mate ina kua huri katoa te extrudate mai i te kapia tukatuka ki te kapia ma, kātahi ka tīmata anō te tīwiri (i roto i te 10 r/min) kia rere ai te kapia ma e toe ana.

02. Me pēhea te horoi tika i te oko?

He tino watea ake, he māmā ake hoki te horoi i te oko i te horoi i te tīwiri, engari he mea tino nui anō hoki.
1) Hei whakarite mō te horoi i te oko, i whakatakotoria hoki te pāmahana o te oko ki te 200°C.
2) Whakawirihia te paraihe maitai porowhita ki te tokotoko wiri me te wiri hiko, ka tāuta hei taputapu horoi, kātahi ka takai i te paraihe maitai ki te mata waea parahi.
3) I mua i te whakauru i te taputapu horoi ki roto i te oko, tauhiuhia he waikawa stearic ki roto i te oko, tauhiuhia rānei he waikawa stearic ki runga i te mata waea parahi o te taputapu horoi;
4) Ina uru te mata waea parahi ki roto i te oko, tīmatahia te wiri hiko kia huri, ā, i taua wā anō me neke whakamua, kia kore ra ano e ātete te nekehanga whakamua, whakamua;
5) I muri i te tango i te mata waea parahi mai i te oko, whakamahia he paihere kakahu miro hei muru i roto i te oko ki mua, ki muri, hei tango i te kapia horoi, i te toenga waikawa ngako rānei; i muri i ētahi murunga ki mua, ki muri, ka oti te horoi i te oko. Kua horoia pai.ngā tīwiri me ngā okokua rite mō te huihuinga mō te mahi whakaputa e whai ake nei!
