3pe pombi yesimbi inodzivirira ngura

3pe pombi yesimbi inodzivirira ngura inosanganisirapombi yesimbi isina musono, pombi yesimbi inotendererauyepombi yesimbi yeLsawChimiro chepurasitiki chekudzivirira ngura chine mativi matatu (3PE) chinoshandiswa zvakanyanya muindasitiri yemapaipi epetroleum nekuda kwekudzivirira ngura kwayo, kupindira kwayo mumvura negasi uye hunhu hwayo hwemakanika.Kurapa uku kunodzivirira ngura kunovandudza zvikuru kuramba ngura kwepombi yesimbi, iyo yakakodzera masisitimu emapaipi akadai sekutumira mafuta, kutumira gasi, kutakurwa kwemvura uye kupa kupisa.

Maumbirwo e3PE simbi yesimbi inorwisa ngura nhanho yekutanga:
Kuputira upfu hweEpoxy (FBE):

Ukobvu hwacho hunosvika 100-250 microns.

Inopa kunamira kwakanaka uye inodzivirira ngura nemakemikari, uye pamusoro pepombi yesimbi zvakabatana zvakanyanya.

 

Rutivi rwechipiri: binder (Namira):

Ukobvu hweinenge 170-250 microns.

Ichinhu chinosunga copolymer chinobatanidza epoxy powder coating ne polyethylene layer.

 

Rutivi rwechitatu: Kuputira kwePolyethylene (PE):

Ukobvu hunenge 2.5-3.7 mm.

Inopa dziviriro yemakanika uye inochengetedza mvura kubva mukukuvadzwa kwemuviri uye kupinda kwehunyoro.

Maitiro ekugadzira pombi yesimbi ye3PE inodzivirira ngura
1. Kugadziriswa kwenzvimbo: pamusoro pepombi yesimbi panenge pakaputirwa jecha kana kupfurwa nepfuti kubvisa ngura, ganda rakasanganiswa neoxidized nezvimwe tsvina uye kunatsiridza kunamira kwependi.

2. Kupisa pombi yesimbi: pombi yesimbi inodziiswa kusvika patembiricha yakati (kazhinji 180-220 ℃) ​​kukurudzira kubatana uye kunamira kwehupfu hwe epoxy.

3. Upfu hwe epoxy hwekuputira: pfapfaidza upfu hwe epoxy zvakaenzana pamusoro pepombi yesimbi inopisa kuti ugadzire chikamu chekutanga chekuputira.

4. Isa chibatiso: Isa chibatiso che copolymer pamusoro pe epoxy powder coating kuti uve nechokwadi chekuti chinobatana zvakasimba ne polyethylene layer.

5. Kuputira nepolyethylene: Chidimbu chekupedzisira chepolyethylene chinoiswa pamusoro pechivharo chebinder kuti chigadzire chimiro chakakwana chine mativi matatu.

6. Kutonhodza uye kugadzika: Pombi yesimbi yakaputirwa inotonhodzwa uye inogadzika kuitira kuti zvikamu zvitatu zvekugadzika zvinyatsobatanidzwa kuti zvigadzire layer yakasimba inodzivirira ngura.

Hunhu uye zvakanakira zvepombi yesimbi ye3PE inodzivirira ngura

1. Kushanda zvakanaka kwazvo mukudzivirira ngura: chimiro chejira rine mativi matatu chinopa dziviriro yakanaka mukudzivirira ngura uye chakakodzera nzvimbo dzakasiyana-siyana dzakaoma dzakadai senzvimbo dzine acidic nealkaline, nzvimbo dzemugungwa nezvimwewo.

2. Hunhu hwakanaka hwemakanika: polyethylene layer ine simba rakanaka uye inodzivirira kukweshana uye inogona kutsungirira kukuvara kwekunze.

3. Kudzivirira kupisa kwakanyanya uye kwakaderera: 3PE anticorrosion layer inogona kuchengetedza kushanda zvakanaka munzvimbo dzese dziri kupisa kwakanyanya uye kwakaderera, uye haisi nyore kutsemuka nekudonha.

4. hupenyu hurefu hwebasa: Hupenyu hwebasa remapaipi esimbi e3PE anodzivirira ngura hunosvika makore makumi mashanu kana kupfuura, zvichideredza mari yekugadzirisa mapaipi uye yekutsiva.

5. kunamira kwakanaka kwazvo: epoxy powder coating uye simbi pombi pamusoro uye pakati pe binder layer ine kunamira kwakasimba kudzivirira kuti coating isabvaruke.

 
Minda yekunyorera

1. Kutakurwa kwemafuta negasi: kunoshandiswa kutakurwa kwemapaipi emafuta negasi rechisikigo kure kudzivirira ngura nekubuda kwemvura.

2. Mapaipi ekufambisa mvura: anoshandiswa mukupa mvura muguta, kudhonza mvura, kuchenesa tsvina yetsvina nedzimwe nzira dzemapaipi emvura, kuitira kuti mvura ive yakachengeteka.

3. pombi yekudziisa: inoshandiswa kutakura mvura inopisa musystem yekudziisa iri pakati kudzivirira ngura yepombi uye kurasikirwa nekupisa.

4. mapaipi emaindasitiri: anoshandiswa muindasitiri yemakemikari, simbi, magetsi nedzimwe nzvimbo dzemaindasitiri dzemapaipi ekugadzirisa, kudzivirira mapaipi kubva mukuora kwemidziyo inoparadza.

5. uinjiniya hwegungwa: hunoshandiswa mumapaipi epasi pemvura, mapuratifomu egungwa nedzimwe nzira dzekugadzira gungwa, zvichidzivirira ngura yemvura yegungwa nezvisikwa zvegungwa.
