Polyolefin Polyethylene PO/PE lining Coating Powder yeSimbi Lining

Plastic coating lined simbi pombi yakavakirwa pane yakajairwa kabhoni simbi pombi, ine kemikari yakanakisa thermoplastic lining. Iyo inogadzirwa neinotonhora yekudhirowa komputa kana kukunguruka kuumba. Iyo ine ese ma mechanic properties yesimbi pombi uye corrosion resistance yepombi yepurasitiki. Iyo ine hunhu hwekuvharisa chikero, kuramba kukura kwemicrobial, zvichiita kuti ive pombi yakanaka yekutakura asidhi, alkali, munyu, magasi anoparadza, uye mamwe midhiya. The thermoplastic coatings anowanzo shandiswa pakugadzira PO, PE, PP, uye PTFE.

PO ndiyo chidimbu chepolyolefin, inova polymer ye ethylene uye iri muchikamu chepamusoro molecular huremu polyethylene. Inogona kuve yakasanganiswa ne ethylene, propylene, butene, uye mamwe maolefins, pamwe nekusanganiswa nezvimwe zvinowedzera kuwedzera zvimiro zvayo. Irwo rudzi rutsva rwemachira ane corrosion resistance, antistatic properties, non-toxicity, high simba, uye good rigidity. Inogona kushandiswa mumhando yekushisa ye -20 ° C kusvika 90 ° C uye inoshandiswa uchishandisa yakakosha kupisa kutenderera kuumba maitiro. Iine mutengo wakaderera uye inoratidza kunamatira kwakasimba kune simbi. Inoshandiswa zvakanyanya mumaindasitiri akadai semakemikari, simbi, chikafu, chekufambisa, mishonga, chlor-alkali, kutumira, migodhi, uye machira. Iyo nzira yekugadzirisa inobvumira kugadzirwa kwezvimiro zvakaoma, zvichiita kuti zvive zvakanyanya kufarirwa nevashandisi.

Se copolymer ye ethylene, propylene, uye butene, PO haingori chete inodzivirira ngura ye ethylene ne propylene asiwo inoratidza kudzivirira kupisa kwakanaka, kudzivirira kukanganiswa, uye hunhu hwemagetsi hwekudziyisa. Tembiricha yayo yekushanda inogona kunge yakakwira nemadhigirii 20-30 kupfuura ye polyethylene. Inokunda kusabatana kwakashata pakati pe polyethylene, polypropylene , uye simbi, ichiratidza simba rakasimba rekubatanidza uye ichivimbisa kubatana kwakasimba nesimbi. Parizvino ndeimwe yezvinhu zvakanakisisa zvinodzivirira ngura pasi rese. Midziyo, mapaipi, uye fittings dzakaputirwa ne PO zvinogona kutsungirira mamiriro e vacuum kusvika -0.092 MPa. Pamusoro pezvo, nekuda kwesimba rayo rakasimba rekubatanidza, inoderedza zvakanyanya shrinkage uye kureba kunokonzerwa nekuchinja kwekupisa. Izvi zvinoita kuti michina, mapaipi, uye fittings dzakaputirwa ne PO dzisakuvadzwe nekudonha kana kuwedzera, zvichivimbisa kugadzikana kwenguva refu. PO yakakodzera kuwanda kwakasiyana-siyana kwe acid, alkali, salt solutions, uye zvimwe zvinonyungudutsa zve organic.

Polyolefin (PO) Lining Coating Zvakanakira:

1. One-piece molding, hapana welding seams, hapana majoini, corrosion resistance, kuchembera kuramba, crack resistance, negative pressure resistance, hapana kusvuura. Ese mabheji anoumbwa anoumbwa muchidimbu chimwe chete, pasina artificial oparesheni majoini uye welding point; nokudaro, vane kuvimbika kwakanaka, havana hurema, uye havana kubvinza.
2. Chero zvikamu zvesimbi zvakaumbwa zvinogona kuiswa, kuiswa nyore uye kugadzirisa, zvinogona kugadziriswa, kuchengetedza mari. Chigadzirwa chacho chine chitarisiko chakatsetseka, chisina mabhubhu, chisina chepfu, uye chisina pinholes.
3. Zvishandiso zvemhando yepamusoro: Zvekupinzwa kunze uye zvepamba zvepololefin resin anonyanya kushandiswa kugadzira marara asingadziviriri emidziyo yekabhoni simbi.
4. Magadzirirwo ehunyanzvi: Zvinoenderana neiyo firimu-forming theory, iyo resin ratio yePO inovandudzwa kuti ikwidzise kushanda kwechikamu chimwe nechimwe cheiyo lining layer.
5. Yakasarudzika yekudziya yekuumba maitiro: Yakasimba tembiricha yekudzora inoitwa pamatanho akasiyana-siyana, zvichiita kuti ive imwe-nguva yekuumba inoshanda mamorekuru crystallization inosanganisira yepasi, dhizaini, uye pamusoro pedhiri, nekudaro inovandudza kushora, kuramba, uye kuumbwa kwekuita. nebhachi.
6. PO inokunda dambudziko rakajairika rechimiro chisina kusimba uye kukuvara kuri nyore kunokonzerwa nechipiri kugadzirisa rabha, PE, PP, uye PVC linings, senge welding (kana body bonding) ye lining materials uye flanging yepombi inopera. Iyo ine mabhenefiti ekuita kwakanaka kwese kwemidziyo kuita, kusimba kwepamusoro, uye kuramba kwakasimba kune hydrofluoric acid.
7. Kuburikidza nekuumbwa kwekupisa, kusarudzwa kwezvinhu, uye kugadziridzwa, PO inosanganisa iyo lining layer nemuviri wesimbi kuita yakasimba uye ine dense yakazara, iyo inogona kushandiswa kwenguva yakareba munzvimbo dzine tembiricha yakakwira kana shanduko yetembiricha kazhinji, kukunda kukuvara kwakasiyana kunokonzerwa nekupisa. kuwedzera uye kuputika kwezvinhu zvisiri-metallic lining zvigadzirwa (senge rabha, PE, PP, uye PVC), zvakadai sekuputika uye delamination.
8. Steel-lined polyolefin (PO) zvigadzirwa zvinoshandiswa zvakanyanya mu petroleum, makemikari, muchina, simbi, mishonga, dhayi, chikafu, biochemical, machira, electroplating, kuchengetedza kwezvakatipoteredza, uye mamwe minda. Iyo corrosion-resistant layer yakagadzikana inopesana neakasiyana siyana einorganic acids, organic acids, alkalis, uye munyu. Icho chinhu chakanakira zvimwe zvinhu zverabha, enamel, fiberglass, simbi isina tsvina, mapepa epurasitiki (pombi), nezvimwewo mukati metembiricha ye -20°C kusvika 90°C.

Zvakanakira zvePolyolefin PO Lining Coating:

Ose ari maviri PO nerabha anowanzo shandiswa midziyo yekumisikidza hydrochloric acid ekuchengetedza matangi, ane yakanakisa kuramba hydrochloric acid corrosion uye yakafanana tembiricha siyana, uye mitengo yavo yakafanana. Kubva pakuongororwa kwemaitiro ePO, PO sechinhu chekugadzika chehydrochloric acid matangi ekuchengetera ine mutengo wepamusoro wekuita reshiyo pane rubber lining, uye zvakanakira zvayo zvinonyanya kuratidzwa mune zvinotevera zvinhu zviviri:

• 1) PO ine yakagadzikana makemikari zvimiro, kuramba kuchembera, uye hupenyu hurefu hwebasa. Hupenyu hwesevhisi hwePO-lined hydrochloric acid ekuchengetedza matangi anogona kusvika makore 30-50, nepo rubha ichiita kuchembera uye hupenyu hwayo hwesevhisi haigone kusvika makore makumi matatu.
• 2) PO ine kunamatira kwakasimba, uye iyo PO lining yakanyatso kusanganiswa neyakaiswa simbi muviri, kunyangwe paine kazhinji tembiricha shanduko, hapazove nekuderera. Rubber lining inotarirwa kuvharika kubva kune dzakamisikidzwa simbi zvikamu, kunyanya sezvo tembiricha inowedzera, inokonzeresa delamination, iyo inogona kukonzera kukora kwezvikamu zvesimbi uye kutungamirira kune hydrochloric acid kuvuza tsaona. Mukuwedzera, rabha yakavharwa inogona kuvhara mapaipi akabatanidzwa.

PE ndiyo chidimbu che polyethylene. PE poda inoshandiswa zvakanyanya mukutenderedza kuumbwa, mukati memadziro emukati mapombi esimbi, uye epurasitiki lining yekudzivirira ngura. Iyo ine yakanakisa kuyerera, yakatsetseka pamusoro, kutsemuka kuramba, asidhi uye alkali kuramba, yakanaka kupisa kupisa, uye kuramba kwezvakatipoteredza kusagadzikana kupaza.

Misiyano yePE Lining Storage Tangi uye PO Lining Storage Tangi

PE inomirira polyethylene, inova iyo thermoplastic material ine yakanaka corrosion resistance uye kusapfeka. Iine high density uye kuoma asi kusimba kusina kunaka. Naizvozvo, matangi ePE anowanzo shandiswa kuchengeta makemikari akadai seasidhi, alkali, uye munyu.

Nekune rimwe divi, PO inomirira polyoxymethylene, inova ipurasitiki yeinjiniya yepamusoro-soro ine makemikari anoshamisa ekusaora uye kusada kupisa. Iyo ine yakaderera density uye kuoma asi yakanaka kuoma. Naizvozvo, matangi ePO anowanzo shandiswa kuchengetedza kudziya kwepamusoro-soro, kudzvanywa kwepamusoro, uye makemikari anoparadza zvakanyanya senge acids, alkalis, esters, uye ketoni.

Mukuwedzera, PE nePO vane mitengo yakasiyana. Nekuda kwekuita kwayo kwepamusoro, PO iri kudhura zvakanyanya. PE, kune rumwe rutivi, ine mutengo wakaderera, ichiita kuti iwedzere kushandiswa mune zvakajairika makemikari ekuchengetedza zvikumbiro.

Muchidimbu, kushandiswa kwePE nePO mumatangi ekuchengetedza epurasitiki ane simbi anosiyana. Kusarudzwa kwezvinhu kunofanirwa kuve kwakavakirwa pane zvinhu zvemakemikari uye kuchengetedza mamiriro.
