Polyolefin Polyethylene PO/PE lining Coating Powder for Zitsulo Lining

Chitoliro cha pulasitiki chokhala ndi chitsulo chimakhala ndi chitoliro chachitsulo cha carbon, chokhala ndi zitsulo zabwino kwambiri za thermoplastic. Zimapangidwa ndi kuzizira kojambula pawiri kapena kugudubuza. Iwo ali zonse makina zimatha zitsulo chitoliro ndi kukana dzimbiri wa pulasitiki chitoliro. Ili ndi mawonekedwe oletsa kukula, kukana kukula kwa tizilombo toyambitsa matenda, ndikupangitsa kuti ikhale payipi yabwino yonyamulira asidi, alkali, mchere, mpweya wowononga, ndi media zina. The zofunda zamoto wa thermoplastic Zomwe zimagwiritsidwa ntchito kwambiri pakumanga ndi PO, PE, PP, ndi PTFE.

PO ndi chidule cha polyolefin, amene ndi polima wa ethylene ndipo ali m'gulu la mkulu maselo kulemera polyethylene. Itha kukhala copolymerized ndi ethylene, propylene, butene, ndi olefins ena, komanso blended ndi zina zowonjezera kumapangitsanso katundu wake. Ndi mtundu watsopano wazitsulo zokhala ndi kukana kwa dzimbiri, antistatic properties, zopanda poizoni, mphamvu zambiri, komanso kusasunthika kwabwino. Itha kugwiritsidwa ntchito pa kutentha kwa -20 ° C mpaka 90 ° C ndikukonzedwa pogwiritsa ntchito njira yapadera yozungulira yozungulira. Ili ndi mtengo wotsika kwambiri ndipo imawonetsa kumamatira mwamphamvu kuchitsulo. Amagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, zitsulo, chakudya, zoyendera, mankhwala, chlor-alkali, kutumiza, migodi, ndi nsalu. Njira yogwiritsira ntchito imalola kupanga mapangidwe ovuta, kuwapangitsa kukhala okondedwa kwambiri ndi ogwiritsa ntchito.

Monga copolymer ya ethylene, propylene, ndi butene, PO sikuti imangosunga kukana kwa dzimbiri kwa ethylene ndi propylene komanso imasonyeza kukana kwabwino kwa kutentha, kukana kukhudza, komanso mphamvu zamagetsi zotetezera. Kutentha kwake kogwira ntchito kumatha kukhala madigiri 20-30 kuposa kwa polyethylene. Imagonjetsa kusagwirizana koyipa pakati pa polyethylene, polypropylene , ndi zitsulo, kuwonetsa mphamvu yamphamvu yolumikizirana ndikutsimikizira kulumikizana kolimba ndi zitsulo. Pakadali pano ndi chimodzi mwazinthu zabwino kwambiri zolimbana ndi dzimbiri padziko lonse lapansi. Zipangizo, mapaipi, ndi zolumikizira zolumikizidwa ndi PO zimatha kupirira mikhalidwe ya vacuum mpaka -0.092 MPa. Kuphatikiza apo, chifukwa cha mphamvu yake yamphamvu yolumikizirana, imachepetsa kwambiri kuchepera ndi kutalika komwe kumachitika chifukwa cha kusintha kwa kutentha. Izi zimatsimikizira kuti zida, mapaipi, ndi zolumikizira zophimbidwa ndi PO siziwonongeka ndi kuchepera kapena kukulira, zomwe zimatsimikizira kukhazikika kwa nthawi yayitali. PO ndi yoyenera mitundu yosiyanasiyana ya acid, alkali, mchere, ndi zosungunulira zina zachilengedwe.

Ubwino Woyatira wa Polyolefin (PO):

1. Kumangirira kwachidutswa chimodzi, kulibe zitsulo zowotcherera, zolumikizira, kukana dzimbiri, kukana kukalamba, kukana ming'alu, kukana kupanikizika, kusasenda. Pamalo onse akalowa amapangidwa mu chidutswa chimodzi, popanda olowa ntchito yokumba ndi mfundo kuwotcherera; choncho, ali ndi umphumphu wabwino, alibe chilema, ndipo alibe kutayikira.
2. Zigawo zilizonse zachitsulo zooneka ngati zingwe, kuyika kosavuta ndi kukonza, zitha kukonzedwa, kupulumutsa ndalama. Mankhwalawa ali ndi mawonekedwe osalala, opanda thovu, opanda poizoni, komanso opanda pinholes.
3. Zipangizo zapamwamba kwambiri: Ma resin a polyolefin ochokera kunja komanso apanyumba omwe amagwiritsidwa ntchito makamaka popanga zomangira zosagwira dzimbiri pazida zachitsulo za kaboni.
4. Kapangidwe kaukadaulo: Malinga ndi chiphunzitso chopanga filimu, chiŵerengero cha utomoni wa PO chimapangidwa bwino kuti chiwongolere magwiridwe antchito a gawo lililonse la mzerewo.
5. Wapadera matenthedwe akamaumba njira: Kuwongolera kutentha kwambiri kumachitika pa magawo osiyanasiyana akalowa, kupangitsa kuti kamodzi akamaumba ogwira maselo crystallization kuphatikizapo wosanjikiza pansi, wosanjikiza structural, ndi pamwamba wosanjikiza, potero kuwongolera kukana dzimbiri, permeability kukana, ndi gulu ntchito ndi jekete.
6. PO imagonjetsa vuto lodziwika bwino la mawonekedwe ofooka komanso kuwonongeka kosavuta komwe kumachitika chifukwa chachiwiri cha mphira, PE, PP, ndi PVC zomangira, monga kuwotcherera (kapena kulumikiza thupi) kwa zida zomangira ndi kuyatsa kwa mapaipi. Ili ndi ubwino wa machitidwe abwino a zida zonse, kukhazikika kwakukulu, komanso kukana kwambiri kwa hydrofluoric acid.
7. Kupyolera mu kuumba kwamafuta, kusankha kwazinthu, ndi kusinthidwa, PO imagwirizanitsa chingwe chachitsulo ndi thupi lachitsulo kuti likhale lolimba ndi wandiweyani, lomwe lingagwiritsidwe ntchito kwa nthawi yaitali m'madera omwe ali ndi kutentha kwakukulu kapena kutentha kwanthawi zonse, kuthana ndi zowonongeka zosiyanasiyana zomwe zimayambitsidwa ndi kutentha. kukulitsa ndi kutsika kwa zinthu zopanda zitsulo (monga mphira, PE, PP, ndi PVC), monga kubwebweta ndi delamination.
8. Zopangira zitsulo za polyolefin (PO) zimagwiritsidwa ntchito kwambiri mu mafuta, mankhwala, makina, zitsulo, mankhwala, utoto, chakudya, biochemical, nsalu, electroplating, kuteteza chilengedwe, ndi zina. Chosanjikiza cholimbana ndi dzimbiri ndi chokhazikika polimbana ndi mitundu yosiyanasiyana ya ma inorganic acid, ma organic acid, alkali, ndi mchere. Ndi njira yabwino yopangira mphira, enamel, fiberglass, chitsulo chosapanga dzimbiri, mapepala apulasitiki (mapaipi), ndi zina zambiri mkati mwa kutentha kwa -20°C mpaka 90°C.

Ubwino wa Polyolefin PO Lining Coating:

PO ndi mphira ndi zida zomwe zimagwiritsidwa ntchito nthawi zambiri poyika matanki osungira a hydrochloric acid, zolimbana bwino ndi dzimbiri la hydrochloric acid ndi kutentha kofananirako, ndipo mitengo yake ndi yofanana. Kuchokera pakuwunika kwa magwiridwe antchito a PO, PO ngati zida zomangira matanki osungira hydrochloric acid ili ndi mtengo wokwera kwambiri kuposa mphira wa rabara, ndipo zabwino zake zimawonekera makamaka muzinthu ziwiri izi:

• 1) PO ili ndi zinthu zokhazikika zamakemikolo, kukana kukalamba, komanso moyo wautali wautumiki. Moyo wautumiki wa akasinja osungira a PO-lined hydrochloric acid amatha kufikira zaka 30-50, pomwe mphira amatha kukalamba ndipo moyo wake wautumiki sungathe kufika zaka 30.
• 2) PO imakhala yomatira mwamphamvu, ndipo PO lining imaphatikizidwa mwamphamvu ndi thupi lachitsulo chokhala ndi mzere, ngakhale ndi kusintha kwa kutentha pafupipafupi, sipadzakhala delamination. Kuyika kwa mphira kumakhala kosavuta kuchoka pazitsulo zokhala ndi mizere, makamaka pamene kutentha kumawonjezeka, kumakhala kosavuta kuti delamination, zomwe zingayambitse dzimbiri zazitsulo ndikuyambitsa ngozi za hydrochloric acid. Kuphatikiza apo, mphira wotsekedwa ukhoza kuletsa mapaipi olumikizidwa.

PE ndiye chidule cha polyethylene. PE ufa chimagwiritsidwa ntchito akamaumba rotational, mkati khoma ❖ kuyanika mapaipi zitsulo, ndi akalowa pulasitiki kuteteza dzimbiri. Imakhala ndi kutulutsa bwino kwambiri, pamwamba posalala, kukana ming'alu, asidi ndi alkali kukana, kukana kutentha kwabwino, komanso kukana kupsinjika kwa chilengedwe.

Kusiyana kwa PE Lining Storage Tank ndi PO Lining Storage Tank

PE imayimira polyethylene, yomwe ndi chinthu cha thermoplastic chomwe sichingadzimbiri bwino komanso kukana kuvala. Ili ndi kachulukidwe kwambiri komanso kuuma koma kulimba koyipa. Chifukwa chake, akasinja a PE nthawi zambiri amagwiritsidwa ntchito posungira mankhwala monga ma acid, alkalis, ndi mchere.

Kumbali inayi, PO imayimira polyoxymethylene, yomwe ndi pulasitiki yaumisiri yochita bwino kwambiri yokhala ndi mankhwala oletsa dzimbiri komanso kukana kutentha. Ili ndi kachulukidwe kakang'ono komanso kuuma koma kulimba kwabwino. Choncho, matanki a PO nthawi zambiri amagwiritsidwa ntchito kusunga kutentha kwambiri, kuthamanga kwambiri, ndi mankhwala owononga kwambiri monga ma acid, alkalis, esters, ndi ketoni.

Kuphatikiza apo, PE ndi PO ali ndi mitengo yosiyana. Chifukwa cha machitidwe ake apamwamba, PO ndiyokwera mtengo kwambiri. PE, kumbali ina, ili ndi mtengo wotsika kwambiri, ndikupangitsa kuti igwiritsidwe ntchito kwambiri posungirako mankhwala.

Mwachidule, kugwiritsa ntchito PE ndi PO m'matangi osungira pulasitiki okhala ndi zitsulo kumasiyana. Kusankhidwa kwa zinthu kuyenera kutengera momwe mankhwalawo alili komanso zinthu zosungirako.
