Kutumiza Molondola Mu Kukonza Fodya

Mu makampani opanga fodya, malamba onyamula katundu sizinthu zongogwiritsira ntchito zinthu zokha—ndi ofunikira kwambiri pa umphumphu wa chinthu, kuwongolera khalidwe, komanso kutsatira malamulo. Kuyambira kukonza masamba obiriwira mpaka kukonza koyamba komanso kupanga ndudu zomaliza, kufunikira kwa makina onyamula katundu ndi kwakukulu kwambiri: kukana fumbi, mphamvu zotsutsana ndi mpweya, kukhazikika kwa mankhwala, komanso kutsatira kwambiri miyezo ya chitetezo cha chakudya ndi pyrolysis.

Kwa mainjiniya a zomera, oyang'anira kugula zinthu, ndi ophatikiza zida omwe akuwunika mayankho operekera, funso ndi lofunika kwambiri: Kodi n'chiyani chimapangitsa kutiLamba wonyamulira katundu wa PEKodi ndi chisankho chotani chomwe chimakondedwa kwambiri pamakampani opanga fodya, ndipo ogula ayenera kuyang'ana chiyani?

A Lamba wonyamulira wa PE (polyethylene)Ndi njira yopepuka yogwirira ntchito yopangidwa ndi chigoba cha nsalu ya polyester ndi polyethylene. Imapereka kukana kukalamba bwino, kukhazikika kwa mankhwala, mphamvu zotsutsana ndi kusinthasintha, komanso kutsatira miyezo ya FDA yotetezera chakudya—zomwe zimapangitsa kuti ikhale yoyenera kwambiri pazofunikira zamakampani opanga fodya.

N’chifukwa chiyani Fodya Amafunika Kugwiritsidwa Ntchito Moyenera? Kumvetsa Ubwino wa Fodya

Kapangidwe ka Zinthu

PE (polyethylene) ndi polima ya thermoplastic yomwe imadziwika ndi kapangidwe kake kosavuta ka molekyulu komanso kugwiritsidwa ntchito kwakukulu. Pakupanga lamba wonyamulira, PE nthawi zambiri imaphatikizidwa ndi wosanjikiza wolimbitsa nsalu ya polyester kuti ipereke kusinthasintha komanso mphamvu yokoka.

Katundu Wofunika Kwambiri

Kufunika kwa Pyrolysis

Chinthu chodziwika bwino cha malamba otumizira fodya ndi kuthekera kwawo kupambana mayeso a pyrolysis—kusanthula kuyaka komwe kumatsimikizira kuti palibe kutulutsidwa kwa mankhwala a nayitrogeni kapena halogenated. Mosiyana ndi PVC yopangidwa ndi pulasitiki, ma polyolefin monga PE amayaka kuti apange carbon dioxide ndi nthunzi yamadzi yokha, popanda zinthu zoopsa. Kutsatira izi ndi chinthu chofunikira kwambiri pazida zamafakitale a fodya.

Mitundu ya Malamba Oyendetsera Zinthu Za PE Ogwiritsira Ntchito Fodya

1. Malamba Osalala a PE

Kapangidwe koyenera ka kunyamula fodya. Malo osalala, osamatirira amatsimikizira kuti zinthu za fodya zimatulutsidwa mosavuta komanso kuchepetsa kumamatira kwa chinthucho. Kukhuthala kwachizolowezi: 0.9mm–2.5mm.

Kugwiritsa Ntchito: Kusamalira masamba obiriwira, mizere yoyambira yopangira, kutumiza kwazinthu zonse.

2. Malamba Ozungulira a Oval Stud PE Conveyor

Yokhala ndi mawonekedwe ozungulira ngati chivundikiro pamwamba, kapangidwe kameneka kamawonjezera kukangana ndi mphamvu yonyamulira, kuteteza kutsetsereka panthawi yonyamula. Yopangidwa ndi zinthu za HDPE, malamba awa ndi othandiza kwambiri pogwira fumbi la fodya ndi kukula kosiyanasiyana kwa zinthu.

Kugwiritsa ntchito: Kusanja, kuumitsa, kudula, ndi kulongedza.

3. Malamba a PE Okhala ndi Mbiri Yopingasa

Kapangidwe ka mbiri yopingasa ya ntchito zomwe zimafuna kugwira kowonjezera ndi kuwongolera zinthu. Kukhuthala kwachizolowezi: 5.0mm.

Kugwiritsa Ntchito: Kutumiza molunjika, kukweza katundu.

4. Malamba a PE Okhala ndi Pattern Yapansi

Pansi pake pali mawonekedwe abwino kuti pakhale kugwedezeka bwino pama rollers oyendetsera. Kukhuthala kwachizolowezi: 5.0mm.

Mafotokozedwe Aukadaulo Pogwiritsa Ntchito

Magawo Ofunika Osankhira

1. Kusankha Kukhuthala

• 0.9mm - 1.2mm: Ntchito zopepuka, zonyamula zathyathyathya
• 2.0mm - 3.0mm: Ntchito zonyamula katundu wapakati komanso wochepa
• 4.0mm - 5.0mm: Ntchito zolemera, zolembedwa bwino, zofunikira kwambiri pakukhala ndi bata

2. Kupezeka kwa M'lifupi

M'lifupi mwachizolowezi nthawi zambiri mumakhala pakati pa 300mm ndi 1000mm, ndipo m'lifupi mwamakonda mumapezeka mpaka 3000mm kutengera wopanga.

3. Mbiri Zapamwamba

4. Zofunikira Zotsutsana ndi Kusasinthasintha

Malamba ambiri a PE a mtundu wa fodya amaphatikiza ulusi woyendetsa pansi kuti achotse mphamvu yosasunthika. Izi ndizofunikira kwambiri popewa kusonkhanitsa fumbi ndikuwonetsetsa kuti wogwiritsa ntchito ali otetezeka m'malo omwe fumbi limakonda kukhala.

Ukadaulo Wosagwiritsa Ntchito Tizilombo Tosaoneka ndi Nthata

Nkhawa yapadera yopangira fodya ndi kuipitsidwa kwa nthata, zomwe zingawononge ubwino wa mankhwala ndi miyezo ya thanzi. Njira zamakono zopangira zimaphatikizapo mankhwala oletsa nthata (monga mankhwala a isothiazolinone) mu PE kapena mankhwala a nsalu. Mankhwalawa amaletsa kuberekana kwa nthata pamene akutsatira malamulo a FDA ndi EU REACH. Ichi ndi chinthu chofunikira kwambiri kwa ogula omwe akufotokoza za lamba wa mtundu wa fodya.
