I-Polyolefin Polyethylene PO/PE lining Coating Powder Yensimbi Yensimbi

Ipayipi lensimbi elakhiwe ngepulasitiki lisekelwe epayipini lensimbi elivamile, elinoqweqwe lwamakhemikhali oluhle kakhulu lwe-thermoplastic. Yakhiwa ngokuhlanganisa okubandayo komdwebo noma ukugoqa. Inakho kokubili izakhiwo zemishini yepayipi lensimbi kanye nokumelana nokugqwala kwepayipi lepulasitiki. Inezici zokuvimbela isikali, ukumelana nokukhula kwamagciwane, okuyenza ibe ipayipi elikahle lokuthutha i-asidi, i-alkali, usawoti, amagesi ezonakalisayo, neminye imidiya. I ama-thermoplastic coatings okuvame ukusetshenziselwa ulayini yi-PO, PE, PP, kanye PTFE.

I-PO isifinyezo se-polyolefin, okuyi-polymer ye-ethylene futhi eyingxenye ye-polyethylene yesisindo samangqamuzana aphezulu. Ingenziwa i-copolymerized nge-ethylene, i-propylene, i-butene, namanye ama-olefin, futhi ihlanganiswe nezithasiselo ezithile ukuze kuthuthukiswe izakhiwo zayo. Iwuhlobo olusha lwempahla yolayini enokumelana nokugqwala, izakhiwo ze-antistatic, ukungabi nobuthi, amandla aphezulu, nokuqina okuhle. Ingasetshenziswa ebangeni lokushisa -20 ° C kuya ku-90 ° C futhi icutshungulwe kusetshenziswa inqubo ekhethekile yokubumba yokujikeleza okushisayo. Inenani eliphansi futhi ibonisa ukunamathela okuqinile ensimbi. Isetshenziswa kabanzi ezimbonini ezifana namakhemikhali, i-metallurgy, ukudla, ezokuthutha, ezemithi, i-chlor-alkali, ezokuthutha, izimayini nezindwangu. Inqubo yokucubungula ivumela ukwakhiwa kwezakhiwo eziyinkimbinkimbi, okwenza ukuthi kuthandwe kakhulu ngabasebenzisi.

Njenge-copolymer ye-ethylene, i-propylene, ne-butene, i-PO ayigcini nje ngokugcina ukumelana nokugqwala kwe-ethylene ne-propylene kodwa futhi ikhombisa ukumelana okuhle nokushisa, ukumelana nokushayisana, kanye nezakhiwo zokushisa zikagesi. Izinga lokushisa layo lokusebenza lingaba ngama-degrees angu-20-30 aphezulu kunele-polyethylene. Inqoba ukunamathelana okubi phakathi kwe-polyethylene, i-polypropylene , kanye nezinsimbi, ikhombisa amandla okubopha aqinile futhi iqinisekisa ukuxhumana okuqinile nezinsimbi. Njengamanje ingenye yezinto ezilungele kakhulu ukumelana nokugqwala emhlabeni jikelele. Imishini, amapayipi, kanye nezinto ezifakwe i-PO zingamelana nezimo ze-vacuum ezifika ku--0.092 MPa. Ngaphezu kwalokho, ngenxa yamandla ayo okubopha aqinile, ikhawulela kakhulu ukugqwala kanye nobude obubangelwa izinguquko zokushisa. Lokhu kuqinisekisa ukuthi imishini, amapayipi, kanye nezinto ezifakwe i-PO azonakaliswa ukugqwala noma ukwanda, okuqinisekisa ukuzinza kwesikhathi eside. I-PO ifanelekela amazinga ahlukahlukene e-acid, i-alkali, izixazululo zikasawoti, kanye nezinye izinto eziphilayo ezinyibilikayo.

I-Polyolefin (PO) I-Lining Coating Izinzuzo:

1. Ukubumba kocezu olulodwa, akukho imithungo yokushisela, akukho amalunga, ukumelana nokugqwala, ukumelana nokuguga, ukumelana nokuqhekeka, ukumelana nengcindezi engalungile, akukho ukuxebuka. Zonke izindawo ze-lining zakhiwe ngocezu olulodwa, ngaphandle kwamajoyinti okusebenza okwenziwa kanye namaphoyinti wokushisela; ngakho-ke, banobuqotho obuhle, abanasici, futhi akukho ukuvuza.
2. Noma yiziphi izingxenye zensimbi ezinokwakheka zingafakwa umugqa, ukufakwa kalula nokugcinwa, zingalungiswa, zonge izindleko. Umkhiqizo unokubukeka okushelelayo, awekho amabhamuza, awanabo ubuthi, futhi awekho amaphinifa.
3. Izisetshenziswa zekhwalithi ephezulu: Amareyini e-polyolefin angenisiwe nasekhaya asetshenziselwa ngokukhethekile ukukhiqiza izintambo ezingagqwali zemishini yensimbi ye-carbon.
4. Ukwakhiwa kochwepheshe: Ngokombono wokwenza ifilimu, isilinganiso se-resin se-PO siyathuthukiswa ukuze kuthuthukiswe ukusebenza kwengxenye ngayinye yesendlalelo somugqa.
5. Inqubo eyingqayizivele yokubumba okushisayo: Ukulawulwa okuqinile kwezinga lokushisa kwenziwa ezigabeni ezihlukene ze-lining, okwenza kube ukubunjwa kwesikhathi esisodwa kwe-crystallization yamangqamuzana okuhlanganisa ungqimba olungezansi, ungqimba lwesakhiwo, nongqimba olungaphezulu, ngaleyo ndlela kuthuthukiswe ukumelana nokugqwala, ukumelana nokuqina, nokusebenza okuyinhlanganisela. ngejakhethi.
6. I-PO inqoba inkinga evamile yesakhiwo esibuthakathaka kanye nokulimala okulula okubangelwa ukucutshungulwa kwesibili kwerabha, i-PE, i-PP, kanye PVC ama-linings, njengokushisela (noma ukubopha umzimba) kwezinto zokwenziwa kolwelwesi kanye nokuphethuka kwamapayipi. Inezinzuzo zokusebenza okuhle kwemishini iyonke, ukuqina okuphezulu, nokumelana okuqinile ne-hydrofluoric acid.
7. Ngokubumba okushisayo, ukukhethwa kwezinto ezibonakalayo, nokuguqulwa, i-PO ihlanganisa ungqimba lolwelwesi nomzimba wensimbi lube yinto eqinile neminyene, engasetshenziswa isikhathi eside ezindaweni ezinamazinga okushisa aphakeme noma izinguquko ezivamile zokushisa, okunqoba umonakalo ohlukahlukene obangelwa ukushisa okushisayo. ukunwetshwa kanye nokufinyezwa kwemikhiqizo yamalayini engeyona eyensimbi (njengerabha, i-PE, i-PP, kanye PVC), njengokubhubhuza kanye nokudumba.
8. Imikhiqizo ye-Steel-lined polyolefin (PO) isetshenziswa kabanzi ku-petroleum, amakhemikhali, imishini, i-metallurgy, imithi, udayi, ukudla, amakhemikhali ezinto eziphilayo, izindwangu, i-electroplating, ukuvikelwa kwemvelo neminye imikhakha. Ungqimba olumelana nokugqwala luzinzile ekugxiliseni okuhlukahlukene kwama-asidi angaphili, ama-organic acid, ama-alkali, nosawoti. Ingenye impahla efanelekile yerabha, koqweqwe lwawo, i-fiberglass, insimbi engagqwali, amashidi epulasitiki (amapayipi), njll. ngaphakathi kwezinga lokushisa elingu-20°C kuya ku-90°C.

Izinzuzo ze-Polyolefin PO Lining Coating:

Kokubili i-PO nenjoloba kuyizinto ezisetshenziswayo ezivame ukusetshenziswa ethangeni lokugcina i-hydrochloric acid, enokumelana okuhle kakhulu ne-hydrochloric acid corrosion kanye namazinga okushisa afanayo, futhi amanani akho ayafana ngokuyisisekelo. Kusukela ekuhlaziyweni kwezici zokusebenza kwe-PO, i-PO njengento yolwelwesi lwamathangi okugcina i-hydrochloric acid inenani eliphezulu lokusebenza kwesilinganiso kune-raber lining, futhi izinzuzo zayo zibonakala ngokuyinhloko kulezi zici ezimbili ezilandelayo:

• I-1) I-PO inezinto zamakhemikhali ezizinzile, ukumelana nokuguga, nempilo ende yesevisi. Impilo yesevisi yamathangi okugcina e-PO-lined hydrochloric acid ingafinyelela eminyakeni engama-30-50, kuyilapho irabha ijwayele ukuguga futhi impilo yayo yenkonzo ayikwazi ukufinyelela iminyaka engama-30.
• I-2) I-PO inokunamathela okuqinile, futhi i-PO lining ihlanganiswe ngokuqinile nomzimba wensimbi ofakwe umugqa, ngisho nokushintsha kwezinga lokushisa okuvamile, ngeke kube khona i-delamination. Ulwelwesi lwenjoloba luthambekele ekuhlukanisekeni ezingxenyeni zensimbi ezinomugqa, ikakhulukazi njengoba izinga lokushisa likhuphuka, lithambekele ekuqhekekeni, okungadala ukugqwala kwezingxenye zensimbi futhi kuholele ezingozini zokuvuza kwe-hydrochloric acid. Ngaphezu kwalokho, irabha ehlukanisiwe ingase ivimbele amapayipi axhunyiwe.

I-PE isifinyezo se-polyethylene. Impushana ye-PE isetshenziswa kakhulu ekubumbeni okujikelezayo, ukumboza odongeni lwangaphakathi lwamapayipi ensimbi, nolwelwesi lwepulasitiki lokuvikela ukugqwala. Inokugeleza okuhle kakhulu, indawo ebushelelezi, ukumelana nokuqhekeka, ukumelana ne-asidi ne-alkali, ukumelana nokushisa okuhle, nokumelana nokuqhekeka kokucindezeleka kwemvelo.

Umehluko we-PE Lining Storage Tank kanye ne-PO Lining Storage Tank

I-PE imele i-polyethylene, okuyimpahla ye-thermoplastic enokumelana nokugqwala okuhle nokumelana nokugqoka. Inokuqina okuphezulu nokuqina kodwa ayiqinile. Ngakho-ke, amathangi e-PE avame ukusetshenziselwa ukugcina amakhemikhali afana nama-acids, ama-alkali, nosawoti.

Ngakolunye uhlangothi, i-PO imele i-polyoxymethylene, okuyipulasitiki yobunjiniyela esebenza kahle kakhulu enokumelana nokugqwala kwamakhemikhali okuhle kakhulu kanye nokumelana nokushisa. Inokuqina okuphansi nokuqina kodwa iqinile. Ngakho-ke, amathangi e-PO ngokuvamile asetshenziselwa ukugcina izinga lokushisa eliphezulu, ukucindezela okuphezulu, namakhemikhali adla kakhulu njengama-asidi, ama-alkali, ama-ester, nama-ketone.

Ngaphezu kwalokho, i-PE ne-PO inamanani ahlukene. Ngenxa yemvelo yayo yokusebenza okuphezulu, i-PO ibiza kakhulu. I-PE, ngakolunye uhlangothi, inenani eliphansi uma kuqhathaniswa, okwenza isetshenziswe kabanzi ezinhlelweni ezijwayelekile zokugcina amakhemikhali.

Kafushane, ukusetshenziswa kwe-PE ne-PO emathangeni okugcina epulasitiki anemigqa yensimbi kuyahluka. Ukukhethwa kwezinto ezibonakalayo kufanele kusekelwe ezintweni zamakhemikhali nezimo zokugcina.
