Makina Ofinyira Mafilimu apulasitiki

Nthawi zambiri si makina amodzi, koma dongosolo kapena gawo lomwe limapangidwa kuti lizitha kukonza zidutswa za filimu za pulasitiki zosweka (monga filimu yaulimi ya PE, matumba oluka a PP, filimu yonyamula LDPE, etc.). Cholinga chake chachikulu ndikuchotsa zowononga zambiri (monga matope, girisi, zotsalira zamakalata, ndi zina zotero) ndi chinyezi chomangika ku tizidutswa ta pulasitiki poyeretsa ndi kutulutsa{3}}liwiro mozungulira, kupereka kuyera kwambiri komanso kutsika kwachinyontho zotsukira kuti zisungunuke motsatira.

Kuyeretsa kwathunthu kwa filimu ndi kuyanika kwa extrusion nthawi zambiri kumaphatikizapo zigawo zotsatirazi, zomwe zimakonzedwa motsatira ndondomekoyi:

1. Dziwe loyeretserapo / dziwe loyandama:

·Ntchito: Zinthu zophwanyidwa zimalowa kaye padziwe ili. Kuyeretsa koyambirira ndi kulekanitsa kachulukidwe kumatheka chifukwa cha kugwedezeka ndi kusuntha kwa madzi.

Mfundo yofunika: Pulasitiki (monga PE, PP) yokhala ndi kachulukidwe kochepa kuposa madzi idzayandama pamwamba pa madzi; Zonyansa zolemera monga matope, miyala, ndi zitsulo zidzamira pansi pa dziwelo. Mapepala ena a zilembo adzalekanitsidwa.

2. Makina otsuka friction:

·Ntchito: Ichi ndiye chida chachikulu choyeretsera. Mapepala apulasitiki otsukidwa kale amalowa m'makina otsuka mikangano.

Mfundo yofunika: Makinawa ali ndi tsinde imodzi kapena ziwiri zotalika-zikuluzikulu mkati mwake, zomwe zimakhala ndi mapeyala. Tsambalo limasokoneza mwamphamvu pepala la pulasitiki ndi madzi, kutulutsa mikangano yamphamvu ndi kukwapula, potero imachotsa madontho amakani (monga mafuta ndi matope amakani).

3. Tsukani thanki ndi madzi oyera:

·Ntchito: Landirani zinthu kuchokera kumakina otsuka mikangano ndikutsuka ndi madzi oyenda kuti muchotse zinthu zoipitsidwa bwino zomwe zimapangidwa panthawi yoyeretsa.

4. Makina ofinyira (zida zazikulu):

·Ntchito: Ichi ndi phata la "kuchepa" kwa dongosolo lonse. Pambuyo potsuka, zinthu zonyowa zimalowa mu chowumitsira chofinya ndipo chinyezi chake chimachepa kwambiri.

Mfundo yofunika: Nthawi zambiri pamakhala ma shaft awiri (kapena amodzi) okhala ndi zowonera mkati mwa makina. Kuthamanga kwambiri-kuthamanga kwa nsonga kumapanga mphamvu yamphamvu yapakati, yomwe imatulutsa chinyontho kudzera mu mesh ya sieve; Nthawi yomweyo, mawonekedwe ozungulira amanyamula zinthu kupita patsogolo ndikupanga kuthamanga kwa mpweya kudzera pampweya wa mpweya kapena njira zamakina pamalowo, ndikuwonjezera chinyezi.

·Zotsatira zake: Chinyezi cha pepala lapulasitiki lokonzedwa chikhoza kuchepetsedwa kufika pa 5% -10% (kapena ngakhale kutsika), kusonyeza malo onyowa komanso otayirira, omwe ali oyenera kwambiri kulowa mwachindunji pamakina otsatirawa.

5. Njira yothandizira:

·Conveyor system: spiral feeder, conveyor lamba, etc., amagwiritsidwa ntchito kulumikiza zida zosiyanasiyana.

· Dongosolo la kayendetsedwe ka madzi: kuphatikizira thanki ya sedimentation, pampu yamadzi, fyuluta, ndi zina zotere, zomwe zimagwiritsidwa ntchito kutsuka madzi oyeretsera, kuyendetsa madzi, kupulumutsa madzi komanso kuchepetsa kutayira kwa zimbudzi.

· Kutaya madzi m'thupi moyenera: kumachepetsa kwambiri chinyezi cha zinthuzo ndipo kumachepetsa kwambiri kugwiritsa ntchito mphamvu kwa kuyanika kotsatira kapena kusungunula granulation (madzi otulutsa nthunzi amafuna kutentha kwakukulu).

·Kupititsa patsogolo khalidwe: Kuyeretsa kwambiri kumatsimikizira chiyero ndi ukhondo wa mapulasitiki opangidwanso, omwe amakhudza mwachindunji ubwino wa particles pambuyo pa granulation.

· Kupanga kosalekeza kokhazikika: Dongosolo lonse litha kupangidwa ngati chingwe cholumikizira chokhazikika, chogwira ntchito bwino komanso ndalama zotsika mtengo.

·Kuteteza chilengedwe ndi kusunga mphamvu: Njira yothandizira kayendedwe ka madzi imatha kuchepetsa kwambiri kugwiritsa ntchito madzi aukhondo komanso kutaya zimbudzi.

Ngati mukufuna kuganizira kugula kapena kukonza chipangizo choterocho, muyenera kulabadira mfundo zotsatirazi:

1. Kusamalira zinthu: Fotokozani momveka bwino mtundu wa filimu yapulasitiki yomwe mukufuna kugwira (monga PE, PP, LDPE, etc.).

2. Kufuna mphamvu: Sankhani kuchuluka kwa ola limodzi potengera kuchuluka kwa bizinesi yanu (monga 500kg/h, 1000kg/h, 2000kg/h, etc.).

3. Mulingo wa kuipitsidwa: Kuchuluka kwa zonyansa za zinthu zopangira (filimu ya mafakitale kapena filimu yaulimi?) kumatsimikizira kulimba kwa gawo loyeretsera (monga ma axis imodzi kapena double axis friction washing) likuyenera kukonzedwa.

4. Zofunikira zachinyezi: Zofunikira zenizeni za chinyezi cha zinthu zotulutsidwa zimagwirizana ndi chitsanzo ndi ntchito ya extruder.

5. Zida zamagetsi: Zigawo zomwe zimakumana ndi madzi ziyenera kupangidwa ndi 304 kapena 316 zitsulo zosapanga dzimbiri kuti ziteteze dzimbiri ndikuwonetsetsa moyo wautumiki ndi ukhondo wa zida.

6. Mulingo wodziyimira pawokha: Kaya makina owongolera okha, kutulutsa kwa slag, ndi ntchito zina ndizofunikira.

7. Mbiri ya ogula komanso pambuyo-ntchito zogulitsa malonda: Sankhani opanga odziwa zambiri komanso okhwima mwaukadaulo kuti zitsimikizire kuti zida zili zokhazikika komanso pambuyo-pantchito zogulitsa.

Makina obwezeretsanso mafilimu apulasitiki, kuyeretsa, ndi kufinya ndi chida chofunikira kwambiri pamakampani amakono obwezeretsanso pulasitiki. Imatembenuza mafilimu a zinyalala zauve ndi zonyansa kukhala zopangira zoyera komanso zogwiritsidwanso ntchito, zomwe ndi gawo lofunikira pakukwaniritsa zobwezeretsanso.
