Chitsulo chopititsira patsogolo njira yopititsira patsogolo chosanjikiza komanso mkati ndi kunja kwa polyethylene wosanjikiza chimakhala cholimba, osati mafupa okhawo achitsulo otetezedwa bwino komanso odalirika mosanjikiza, olimba komanso osakanikirana pakati pakhoma lamkati ndi akunja nawonso sanaphatikizidwe ndi ming'alu pa mawonekedwe, amathetsa kuthamanga kwa chubu kapena chimbudzi chowononga chingayambitse kukokoloka ndi kuwonongeka kwa mapaipi, ndi mtundu watsopano wazinthu zapamwamba kwambiri.
Makhalidwe:
● Kuthamanga kwakukulu: poyerekeza ndi machubu ena olimba olimba, kuthamanga (10 mpaka 35 TMPa)
● Kukana dzimbiri: kukana kwamphamvu asidi, alkali, mchere ndi zina zotulutsa mankhwala
● Kutentha kwabwino: kutentha kwapakati kumatuluka nthawi yomweyo, kukula kwa kuchepa kopitilira kamodzi chitoliro cha polyethylene.
● Kuyenda kwakanthawi ndi kocheperako: mkatikati mwamphamvu ya chitoliro chachitsulo ndi 1/20 yokha ya chitoliro chachitsulo, ndipo palibe kukulira, palibe sera, osati chifukwa cha dzimbiri, kukulitsa ndi zina zotengera mphamvu zoyendera zimachepa, chifukwa chake mphamvu zoyendera madzi Zitsulo chitoliro ndi mkulu, zotsatira za mphamvu zopulumutsa ndi chidwi.
Kulemera kwapepuka: pansi pamlingo wofanana, kumakhala kopepuka kuposa chitoliro cholimba cha khoma chomwecho, chomwe chimachepetsa mtengo wonse wa ntchitoyi.
● Opanda poizoni: ukhondo wabwino, kuthetsa vuto lakuwonongeka kwachiwiri kwa madzi akumwa, mogwirizana ndi GB / T17219-1998 zowunikira chitetezo.
● Kulumikizana kodalirika: payipi imalumikizidwa ndi Kutentha kwamagetsi, zomangamanga zosavuta, njira yosavuta yodalirika, imatha kufikira dongosolo lonse la payipi popanda kutuluka.
● Kudzionetsera nokha: kubisidwa pansi kumatha kugwiritsidwa ntchito pambuyo poyesa maginito kuti mupeze malowa, kuti mupewe kuwonongedwa kwa zinthu zina zomangamanga.
● Kuphatikizana kosasunthika komanso kosasintha: chitolirochi ndi cholimba, chabwino kukana, kukhazikitsa ndi kugwiritsa ntchito sikuwopa kugundana; Ndipo imasinthasintha bwino, itha kukhala yoyenera kupindika ndi mawonekedwe azomwe zikuyenda ndi zotsika, kupatula zovekera chitoliro.
● Moyo wautali: Utumiki wa moyo ukhoza kufikira zaka zoposa 50.
Kuyika ndi Kugwiritsa Ntchito Njira
Kumanga bwino, mtengo wotsika, ndipo palibe kukumba mumsewu.
Mapangidwe a 5.1.2.1 Polyethylene (PE)
(1) Kuchuluka kwa ntchito: polyethylene (Pe) chitoliro ndi oyenera kuteteza moto, madzi, ngalande, ulimi wothirira, kuteteza kutentha ndi kayendedwe ka mpweya, ndi zina zambiri.
(2) Ntchito yayikulu ya chitoliro cha polyethylene ikuwonetsedwa mu Gome 5-26.
Ntchito zosiyanasiyana
● Umisiri wamatauni: kapangidwe ka madzi m'mizinda ndi ngalande, madzi akumwa, gasi wachilengedwe, payipi yamagesi.
● Kupota, kusindikiza ndi kupaka utoto, makampani opanga mapepala:
● Makampani opanga mankhwala: acid, alkali, kupanga mchere, petrochemical, feteleza wamankhwala, mankhwala ophera tizilombo, mankhwala, mankhwala, migodi, mafakitale a labala ndi apulasitiki ndi mpweya wina wowononga, madzi, ufa wolimba woperekera chitoliro ndi chitoliro
● Malo opangira mafuta ndi gasi: mapaipi osonkhanitsa ndi kunyamula zimbudzi zonyamula mafuta, kusakaniza kwa gasi, kupukusanso mafuta poyatsira polima, komanso mapaipi oyendetsera mafuta achiwiri komanso apamwamba.
● Mgodi wa malasha: madzi, ngalande, mpweya wabwino, ngalande za gasi ndi kupopera mankhwala.
● Zaulimi: chitoliro chakuya, chitoliro cha fyuluta, njira yoperekera pansi pa nthaka, chitoliro cha ngalande, madzi othirira ndi zina zambiri.
● Makampani opanga zomangamanga: mapaipi azombo zonyamula zonyamula zonyamulira, mapaipi oyendetsa ngalande, okhala ndi mapaipi ndi ma payipi olowera mpweya, ndi zina zambiri.
● Kuyendetsa madzi am'nyanja: makina ophera mchere wamphepete mwa nyanja, malo opangira magetsi a m'mphepete mwa nyanja, kutolera madzi am'nyanja yam'madzi, mapaipi oyenda pansi pamadzi ndi chingwe cholumikizira (chingwe), ndi zina zambiri.
● Thermoelectric engineering: kayendedwe ka madzi akumadzi, mayendedwe a zinyalala.
● Msewu waukulu: chitoliro chojambulidwa ndi ngalande.
