Thumba la 3 PE fyuluta limapindula pantchito zovuta

A PE fyuluta thumbaili ndi maubwino atatu ofunikira pakugwirira ntchito movutikira:

• Kutentha kwakukulu kumapangitsa kuti ntchito ikhale yokhazikika pakatentha kwambiri.
• Kukana kwa Chemical kumateteza kuzinthu zowopsa.
• Kukhazikika kumatsimikizira kugwiritsidwa ntchito kwanthawi yayitali, ngakhale pamavuto.

Zinthu izi zimakumana ndi zovuta zamagwiritsidwe amakono amakampani.

1. Kukana Kutentha Kwambiri

PE fyuluta thumba kutentha kukana

Matumba osefera a PE amawonekera m'malo ovuta momwe kutentha kumatha kusokoneza kusefera. Amasunga umphumphu pa kutentha mpaka 150 ° C (302 ° F), kuwapangitsa kukhala chisankho chodalirika m'mafakitale ambiri. Ngakhale matumba a Teflon ndi PTFE amatha kutentha kwambiri, matumba a fyuluta a PE amapereka njira yotsika mtengo pa ntchito zambiri zotentha kwambiri. Mapangidwe awo apadera a polima amakana kusungunuka ndi kusinthika, zomwe zimathandiza kupewa kulephera kwa fyuluta panthawi yogwira ntchito mosalekeza.

Chidziwitso: Matumba osefera a PE amapereka malire pakati pa magwiridwe antchito ndi kukwanitsa, makamaka poyerekeza ndi zida zotsika mtengo zotentha kwambiri.

Industrial ntchito kutentha kwambiri

Mafakitale ambiri amadalira matumba a fyuluta ya PE kuti asunge njira zikuyenda bwino pansi pa kutentha kwambiri. Nazi zina zomwe zimagwiritsidwa ntchito nthawi zambiri:

• Kupanga zakudya: Ophika buledi ndi opanga zokhwasula-khwasula amagwiritsa ntchito matumba a fyuluta ya PE kusefa mafuta ndi ma syrups panthawi yotentha kwambiri.
• Kupanga zamagetsi: Matumbawa amathandiza kuchotsa tinthu tating'onoting'ono m'mabafa otentha omwe amagwiritsidwa ntchito popanga ma boardboard.
• Kubwezeretsanso zosungunulira: Malo obwezeretsa zosungunulira pa kutentha kokwera zimadalira matumba a fyuluta ya PE kuti azikhala oyera komanso kuteteza zida.

Chikwama chosefera cha PE chimapereka zotsatira zofananira m'malo omwe kutentha kumatha kuwononga zinthu zina mwachangu. Kudalirika kumeneku kumachepetsa nthawi yochepetsera komanso yokonza, ndikupangitsa kuti ikhale njira yabwino kwambiri pantchito zovuta.

2. Kukana kwa Chemical

PE fyuluta thumba mankhwala kukana

Chikwama cha fyuluta cha PE chimapereka kukana kwambiri kwa mankhwala osiyanasiyana. Zinthu za polyethylene zimayimira ma acid, alkalis, ndi zosungunulira zambiri za organic. Kukana kumeneku kumathandiza kupewa kuwonongeka kwa thumba ndi kuipitsidwa kwa zinthu zosefedwa. Poyerekeza ndi zida ngati nayiloni, zomwe zimatha kusweka m'malo ovuta, thumba la fyuluta la PE limasunga mawonekedwe ake ndi magwiridwe ake. Mafakitale ambiri amasankha izi chifukwa chotha kuthana ndi zinthu zankhanza popanda kutaya kusefera.

Langizo: Nthawi zonse yang'anani tchati chofananira ndi mankhwala musanasankhe chikwama chosefera kuti mugwiritse ntchito mwapadera.

Mapulogalamu okhala ndi mankhwala ovuta

Mafakitale omwe amagwira ntchito ndi mankhwala olimba amadalira matumba a fyuluta ya PE kuti azisefera motetezeka komanso mogwira mtima. Nazi zochitika zenizeni:

• Zomera zosungunulira zosungunulira zimagwiritsa ntchito matumbawa kuti zisefe zonyansa kuchokera ku zosungunulira zamphamvu, kuteteza zida ndi zinthu zomaliza.
• Malo oyikamo a Cleanroom amadalira kukana kwamankhwala kwa matumba a fyuluta a PE kuti zinthu zodzitchinjiriza zisaipitsidwe.
• Ntchito zomaliza zazitsulo nthawi zambiri zimagwiritsa ntchito matumbawa kuti azisefa ma acidic kapena alkaline, kuwonetsetsa kuti kupanga bwino komanso kukhala ndi moyo wautali wa zida.

Chikwama cha fyuluta cha PE chimapereka mtendere wamumtima m'malo omwe kukhudzidwa kwamankhwala kumakhala kosalekeza. Ogwira ntchito ndi oyang'anira amafotokoza kulephera kwa matumba ochepa komanso kutsika pang'ono, zomwe zimapangitsa kuti pakhale zokolola zambiri komanso kutsika mtengo wokonza.

3. Kukhalitsa mu Malo Ovuta

Kukhazikika kwa thumba la PE

Chikwama cha fyuluta cha PE chimadziwika chifukwa cholimba. Opanga amapanga matumbawa kuti athe kuthana ndi kupsinjika kwakuthupi, kukhumudwa, ndikugwiritsa ntchito mobwerezabwereza. Zinthuzo zimalimbana ndi kung'ambika ndi kuphulika, ngakhale zitakhala ndi tinthu tating'onoting'ono tating'onoting'ono kapena tating'onoting'ono. Ogwiritsa ntchito ambiri amanena kuti matumbawa amasunga mawonekedwe awo ndi kusefera pambuyo pa maulendo angapo. Kukhalitsa kumeneku kumachepetsa kufunika kosinthidwa pafupipafupi komanso kumathandiza kuwongolera ndalama zogwirira ntchito.

• Masoko olimba: Kusoka mwamphamvu kumateteza kutayikira komanso kumatalikitsa moyo wa thumba.
• Zinthu zokhuthala: Nsalu ya polyethylene imapereka chitetezo chowonjezera kuti isagwe ndi kung'ambika.
• Kuchita kosasintha: Chikwamacho chimapitilira kusefa bwino, ngakhale mutakumana ndi zovuta.

Zindikirani: Malo omwe amagwiritsa ntchito matumba a PE fyuluta nthawi zambiri amawona zododometsa zochepa chifukwa cha kulephera kwa thumba.

Moyo wautali komanso zokumana nazo za ogwiritsa ntchito

Ogwiritsa ntchito m'mafakitale monga zitsulo, kukonza mankhwala, ndi kupanga zakudya amayamikira moyo wautali wautumiki wamatumbawa. Oyang'anira malo ambiri amagawana malingaliro abwino okhudza kudalirika kwa chikwama cha PE fyuluta pakugwira ntchito kwa tsiku ndi tsiku. Amatsindika ubwino wotsatirawu:

• Kuchepetsa nthawi yopuma: Kusintha kwa thumba lochepa kumatanthauza kusokoneza pang'ono kupanga.
• Kutsika mtengo wokonza: Matumba okhazikika amafunikira kusinthidwa pafupipafupi.
• Chitetezo chokwanira: Matumba omwe salephera kupanikizika amathandiza kuti malo ogwira ntchito azikhala otetezeka.

Chikwama chosefera cha PE chimapereka magwiridwe antchito odalirika, ngakhale m'malo ovuta kwambiri. Kudziwika kwa moyo wautali kumapangitsa kukhala chisankho chodalirika pantchito zovuta.

• Kukana kutentha kwambiri, kukana kwa mankhwala, komanso kulimba kumayika thumba la fyuluta la PE padera pa ntchito zovuta.
• Izi zimathandizira kusefa kodalirika m'malo ovuta.
• Oyang'anira malo omwe akufuna njira zosefera zogwira mtima ayenera kuganizira izi kuti azigwira bwino ntchito komanso kuti azikhala ndi nthawi yayitali.

Lumikizanani ndi kusefera kolondolatsopano kuti mutenge thumba la PE fyuluta!
