Te tapahi i ngā matūriki o ngā rahi rerekē? Te whakapūpū me te whakapūpū

Ko te rahi o ngā matūriki e pā ana ki te noho mai o tētahi maha o ngā matūriki nunui, iti rānei i roto i te hua. Ko ngā matūriki nunui matūriki me te rahi neke atu i te 5mm i ngā taha katoa, tae atu ki ngā matūriki tonu. Mena kua whakaritea tō mata wiri kia 8mm te whānui o te mata hei tirotiro i ngā rauemi nunui, ka tino uru ngā rauemi he 5~8mm te whānui ki roto i ngā rauemi hua mā te mata wiri i te wā e whakahaerehia ana te mata wiri.
Ko ngā matūriki iti he matūriki he iti iho i te 2 mm te rahi i tētahi ahunga, tae atu ki ngā maramara me ngā matūriki pakaru.
Kātahi ka tātarihia e mātou ngā take mō te hanganga o ngā matūriki nunui me ngā matūriki iti.

take

Te pāmahana whakamahana tauira

Ko te pāmahana whakamahana o te tauira he pānga tika ki te pai o te haere o te rauemi rewa i roto i te awa hanga o te tauira kirikiri. Ko te tauira e whakamahia ana i roto i tēnei taputapu he tauira momo awa wera. Ka whakamahanahia te hinu wera pāmahana teitei mai i roto kia mau tonu te āhua rewa o te kapia. Ka tohatohahia ngā kōhao mate ki runga i te tauira. Mēnā he ōrite te tere tuku o ia kōhao mate ka taea te tapahi i ngā matūriki he rite te rahi.

Ki te kore e ōrite te whakahaere pāmahana, ka kore e ōrite te tere rere o te rauemi i roto i ētahi kōhao mate. I raro i te mahi a te taputapu tapahi kirikiri, ka puta mai ngā matūriki koretake o ngā roa rerekē, ka pā kino ki te kounga o te hua. Nā te mea ehara te pūnaha hinu wera o tēnei taputapu i te hoahoa kati, he ngāwari te whakawaro i te hinu wera i te wā e whakamahia ana. He ngāwari te aukati, te piri rānei o ngā rauemi waro ki te awa rere i te wā e rere ana te pūnaha hinu wera, ka puta te wera kore ōrite. Hei tāpiri, nā ngā take hoahoa, ka tukuna te paipa hinu wera ki te tūranga teitei. Ki te kore e hiritia tika te pūnaha hinu wera, ka ngāwari te tomo o te hau, ka puta te rerekētanga o te pēhanga o te pūnaha me te wera kore ōrite o te tauira.

Hei tāpiritanga, ina whakaputa hua he iti te rere o te rewa, ka roa te wā e oma ana te tauira, ā, ka noho tonu he iti noa te carbide e uru ana ki te tauira i roto i te tātari pore-nui e whakamahia ana. Mā te kohikohinga roa ka āraia te kōhao pokepokea ai. Ina haere te kapia mā roto i te kōhao pokepokea ai, ka puta he matūriki nui, he matūriki iti hoki. He rerekē te ātete me te tere o te puta i roto i te kōhao mate.

Tapapa

Ka taea hoki e te pakaru, te pakaru rānei o te taputapu tapahi te whakaputa i ngā matūriki nunui, iti rānei. Ka pā tika te pēhanga whāngai o te taputapu tapahi ki te roa o ngā matūriki me te roa o te mahi a te taputapu tapahi. Ka hua ake he aituā pakaru o te maripi i te nui rawa o te pēhanga whāngai, ā, ka hua ake he aituā tukinga o te maripi, he aituā whiri rānei i te maripi, ka pā kino ki te kounga o te whakapūtanga o te pereti.

Ka pāngia te taputapu tapahi e ngā āhuatanga o te rauemi me te tukanga, ā, kua tino tawhito; i te wā e whakahaerehia ana te mīhini whakaputa, ka tere rawa te piki me te heke o te kawenga, ka puta he panoni nui ki te pane tapahi, ā, ka ngawari te pakaru o te taputapu tapahi; i te wā e whakawhiti ana i te mata o te mīhini huri mata, nā te mea kāore te hau o roto e tukuna ma, ka puta te hau toenga i roto i te mīhini huri mata mai i te tauira ki roto i te rūma wai, ka puta he panoni nui ki te pēhanga o te mīhini huri mata. Mā ēnei take ka heke te āhua o te mahi a te mīhini huri mata, ā, kāore e ōrite te hanga o te mīhini huri mata, ka puta he witi nui, he iti hoki. I roto i ēnei, ina teitei ake te tere o te maripi i te tere tuku rauemi, ka piki ake ngā matūriki iti. Engari, ina iti iho te tere o te maripi i te tere tuku rauemi, ka piki ake ngā matūriki nui. I tēnei wā, ko te tere tapahi o tēnei taputapu ka whakahaerehia i te 300~600r/min. I ia wā ka piki ake, ka heke iho rānei te kawenga mā te kotahi tana, whakatikatikahia kia piki ake, kia heke iho rānei mā te 5r/min.

Kāore i te tika te pāmahana o te wai whakamatao

I roto i te tukanga tīmatanga o te waeine whakapūkara, ko tētahi o ngā mea nui e whakatau ana i te angitu o te tīmatanga ko ngā huinga e toru o te "wai", te "maripi" me te "rauemi" i te wā kotahi. Arā, me mahi ngātahi ngā tukanga e toru o te wai whakamatao e tomo ana ki te rūma wai, te hurihanga o te pane tapahi pelletizer, me te tuku tauira kia angitu ai te tīmatanga. Ko te tautuhinga pāmahana o te wai whakamatao tētahi o ngā mea nui.

I muri i te urunga o te wai whakamatao ki te rūma wai, ka tere te whakamatao o te tauira, inā koa ko te haurua o raro o te tauira te mea tuatahi ki te pā ki te wai whakamatao. Mēnā he koretake te tautuhinga pāmahana o te wai whakamatao, ka āraia pea te kōhao mate i te haurua o raro o te tauira i roto i te wāhi nui. Ka uaua te whakatuwhera i te kōhao mate kua āraia e te polymer i te hanga i muri mai, ka puta te kōhao tuku o te tauira. Kāore i te ōrite te tere, he rerekē te pānga tapahi, ā, ka puta he "ngā kōhao nui me ngā kōhao iti". Ka whakaitihia hoki e te pāmahana wai whakamatao koretake te roa o te ora o te taputapu tapahi.

Tetahi take

I te wā e whakaputa ana i ngā hua polypropylene me ngā momo MFR me te rapa, me whakarerekē ngā tawhā tukanga whakahaere o te pelletizer. Ki te kore e tika te whakatakoto i ngā tawhā, ka kore e tika te tere o te pelletizer me te āputa i waenga i te cutter me te tauira, ka hua ake hoki he kore taurite. pelletizing, ka hua ake he witi nui, he witi iti hoki.

whakapai ake

Mana whakahaere pēhanga maripi, mana whakahaere pāmahana wai whakamatao

Ko te rahi o te pēhanga o te maripi te mea e whakatau tika ana i te kounga o te āhua o te kōhao. Mā te pēhanga nui rawa o te maripi ka tata ake te maripi ki te tauira, ka pakaru te taputapu tapahi, ka pakaru hoki te maripi. Mā te pēhanga iti rawa o te maripi ka piri te maripi. , maripi papa. Nō reira, he tino whakahaere te pēhanga o te maripi i te (0.2±0.05) MPa.
Ki te iti rawa te pāmahana o te wai whakamatao, ka āraia ngā kōhao o te tauira, engari ki te teitei rawa te pāmahana, ka puta te ngaunga me te ngaunga tonu. Nō reira, mā te whakahaere tika i te pāmahana o te wai whakamatao me te pupuri i te pāmahana ki te 50~65℃ ka taea te whakaiti i te hanganga o ngā matūriki nunui me ngā matūriki iti.

Whakakapia te taputapu tapahi granulation me te uara pH o te wai whakamatao i te wā tika.

Ka pā te waikawa me te kawakore o te wai whakamatao ki te tuara o te taputapu tapahi. Nā te mea i ahu mai te wai whakamatao i roto i tēnei taputapu i te wai kua tangohia te tote, he waikawa te pH=6. Nō reira, kia roa ake ai te ora o te taputapu tapahi, kia kore ai hoki e pakaru ohorere te taputapu tapahi i te wā e whakamahia ana mō te wā roa, me whakapakari ake te aroturuki i te taputapu tapahi, me te whakakapi i te mata i te wā tika. Ka taea hoki te tāpiri i te kawakore ngoikore e tika ana hei whakarerekē i te pH o te wai whakamatao kia noho kūpapa ake, kia whakaitihia ai te tūponotanga o te waikura.

Whakapakari ake i te aroturukitanga me te whakahaeretanga o ia rā

Hei whakahaere i te kounga o te āhua o ngā matūriki, ka whakapakarihia te tirotiro i te āhua o ngā matūriki i te wā e kohia ana te tauira. I te wā e kohia ana te tauira, me āta tirotiro te kaiwhakahaere i te āhua o ngā matūriki. Mena he nui, he iti rānei ngā matūriki, me whakamōhio wawe atu ki ngā kaimahi tukanga me ngā taputapu kia tirohia, kia mahi tahi hoki me te taputapu tapahi. I taua wā anō, whakapā atu ki ngā kaimahi whakamātautau kia arotakehia te rahi o ngā matūriki. Me whakapakari ake te mahi tirotiro, ā, ina kitea he nui, he iti hoki ngā matūriki, me whakarerekē ngā tawhā tukanga i te wā tika, ā, me tatau te tere whakatuwheratanga.

(tere whakaputa × te maha o ngā matūriki × 1000) ÷ (te maha o ngā mata × te tere o te maripi × 60) = te maha o ngā kōhao maeneene i roto i te tātai: te tere whakaputa o kg / h; te maha o ngā matūriki i roto i te g; te tere o te pelletizer r / min (te maha o ngā kōhao ÷ te maha o ngā kōhao i roto i te pokepokea ai) × 100% = te tere o ngā kōhao tuwhera.
