ISO 21809-1Isebenza kwiinkqubo zemibhobho engcwatyiweyo okanye entywiliselweyo kwishishini leoli negesi kwaye ichaza iimfuno zokhuselo lokutya kwangaphandle.I-3LPE kunye ne-3LPPngenxaimibhobho yentsimbi edityanisiweyo nengenamthungo.
Kukho iindidi ezintathu zemathiriyeli yokujonga phezulu, ngokuxhomekeke kuhlobo lwemathiriyeli yokujonga phezulu:
A: I-LDPE (i-polyethylene ephantsi koxinaniso);
B: I-MDPE / HDPE (i-polyethylene yoxinaniso oluphakathi) / (i-polyethylene ephezulu);
C: PP (Polypropylene).
Iimfuno zoxinaniso zemathiriyeli nganye zichazwe ngokweenkcukacha kweli candelwana lilandelayo kwiimfuno zemathiriyeli ekrwada.
| Iklasi yokwaleka | Izinto zomaleko ophezulu | Ubushushu boyilo (°C) |
| A | I-LDPE | -20 ukuya + 60 |
| B | MDPE/HDPE | -40 ukuya + 80 |
| C | PP | -20 ukuya + 110 |
Inkqubo yokwambathisa iya kuba nemigangatho emithathu:
Uluhlu lokuqala: i-epoxy (ulwelo okanye umgubo);
Uluhlu lwe-2: i-adhesive;
Umaleko we-3: PE / PP umaleko ophezulu osetyenziswa yi-extrusion.
Ukuba kuyimfuneko, idyasi erhabaxa ingafakwa ukunyusa ukuxhathisa ukutyibilika.Ngokukodwa apho kufuneka ukubamba okuphuculweyo kunye nomngcipheko oncitshisiweyo wokutyibilika.
Epoxy Resin Layer Ukutyeba
Ubuninzi be-400 um
Ubuncinane: Ulwelo epoxу: ubuncinane 50um;FBE: Ubuncinci be-125um.
Ukutyeba koMaleko okuncamathelayo
Ubuncinci be-150um kumzimba wombhobho
Ukutyeba okupheleleyo kokutyabeka
Inqanaba lobunzima bomaleko ochasene ne-corrosion lutshintshwa kunye nomthwalo wesiza kunye nobunzima bombhobho,kunye nenqanaba lokutyeba kwe-anti-corrosion layer kufuneka likhethwe ngokwemiqathango yokwakha, indlela yokubeka umbhobho, iimeko zokusetyenziswa, kunye nobukhulu bombhobho.
I-Pm bubunzima bombhobho wentsimbi ngemitha.
enokubuzwa ngokubonisana ehambelanayoitafile yobunzima bomgangatho wombhobho wensimbi, okanye ngefomula:
PM=(DT)×T×0.02466
I-D yi-diameter yangaphandle echaziweyo, ebonakaliswe nge-mm;
T bubukhulu bodonga obuchaziweyo, obubonakaliswe kwi-mm;
Iimfuno ze-Epoxy Material
Iimfuno ze-Adhesive Material
Iimfuno zePE/PP Umaleko ophezulu
Inkqubo yokunqanda ukubola inokwahlulwa ngokurhabaxa ibe:
1. Ukulungiswa komphezulu;
2. Ukufaka isicelo sokugquma
3. Ukupholisa
4. Ukunciphisa
5. Ukumakisha
6. Ukuhlolwa kwemveliso egqityiweyo
1. Ukulungiswa komphezulu
Iimfuno ezifanayo zifumaneka kwimigangatho ye-SSPC kunye ne-NACE, kwaye oku kulandelayo yimbalelwano ngokubanzi:
| ISO 8501-1 | NACE | I-SSPC-SP | Ukutyunjwa |
| Sa 2.5 | 2 | 10 | Ukucoca intsimbi ekufutshane-emhlophe |
| Ngomhla wesi-3 | 1 | 5 | Ukucocwa kokuqhuma kwentsimbi emhlophe |
Nceda uqaphele ukuba umphumo we-Sa 2.5 awulungiswanga ngokuxhomekeke kwibakala lokubola lombhobho wensimbi, oluhlulwe njenge-A, B, C, kunye ne-D, ehambelana nemiphumo emi-4.
2. Isicelo sokugquma
Qinisekisa ukuba ukushisa kwangaphambi kokushisa kunye nesantya somgca wombhobho wensimbi kwinkqubo yokugcoba ifanelekile ukufezekisa ukunyangwa okupheleleyo kwepowder powder kunye nokuqinisekisa ukunamathela kwengubo kunye nokulawula ubuninzi bengubo.
Ubunzima bomgangatho wokukhusela ukubola kwakhona kuhambelana neeparitha zezixhobo zokugquma.
3. Ukupholisa
Ingubo esetyenzisiweyo iya kupholiswa kwiqondo lokushisa elithintela ukuphatha umonakalo ngexesha lokugqiba kunye nokuhlolwa kokugqibela.
Ngokubanzi, iqondo lokupholisa le-3LPE alikho ngaphezu kwe-60 ℃, kwaye iqondo lokupholisa le-3LPP liya kuba phezulu kancinci.
4. Ukunciphisa
Ubude obuthile bokugquma kufuneka bususwe kuzo zombini iziphelo zombhobho kwaye umaleko wokukhusela ukubola akufanele ubhengezwe kwi-angle engaphezu kwama-30 ° ukukhusela umonakalo onokwenzeka kwi-coating yokukhusela i-corrosion ngexesha le-welding.
5. Ukumakisha
Ukuthotyelwa kwemigangatho kunye neemfuno zabathengi.
Ezi mpawu kufuneka zenziwe ngestensile okanye zipeyintwe ukuqinisekisa ukuba umbhalo ucacile kwaye awufihli.
6. Ukuhlolwa kweMveliso egqityiweyo
Uhlolo olubanzi lwemibhobho egqityiweyo yokulwa nomhlwa ukuhlangabezana neemfuno ze-ISO 21809-1.
3LPE izicelo
Iingubo ze-3LPE zinika ukuxhathisa kweekhemikhali eziphezulu, ukukhuselwa ngoomatshini kunye nokuqina okulungileyo, kunye neendleko eziphantsi zokugcinwa.
Ifanelekile kwimibhobho engcwatywayo okanye engaphantsi kwamanzi efuna ukuxhathisa kwe-corrosion ephezulu kunye nokukhuselwa komatshini kwiindawo zomhlaba kunye namanzi.
