Samfur Description

3PE waje anti-lalata bututun ne a yadu amfani anti-lalata fasahar, yafi amfani da waje surface anti-lalata bututun mai da gas da kuma birane samar da ruwa bututu. 3PE yana tsaye ne don polyethylene mai Layer uku, wanda shine tsarin rufewa wanda ya ƙunshi yadudduka uku:

3PE waje anti-lalata bututun ne a yadu amfani anti-lalata fasahar, yafi amfani da waje surface anti-lalata bututun mai da gas da kuma birane samar da ruwa bututu. 3PE yana tsaye ne don polyethylene mai Layer uku, wanda shine tsarin rufewa wanda ya ƙunshi yadudduka uku:

FBE primer Layer (fused epoxy foda): A matsayin farkon Layer, FBE Layer yana ba da kyakkyawar haɗin kai ga matrix bututun ƙarfe kuma yana da kyawawan kaddarorin rigakafin lalata.

M Layer: Layer na tsakiya yana aiki a matsayin manne don tabbatar da haɗin kai tsakanin Layer FBE da polyethylene na waje, yayin da yake samar da wani ƙarfin injiniya.

Polyethylene na waje mai kariya: Layer na waje shine babban polyethylene mai girma (HDPE), wanda ke ba da kariya ta inji, hana ruwa da juriya ga yashwar muhalli.

Halayen 3PE anti-lalata Layer sun haɗa da:

Kyawawan kaddarorin inji da kaddarorin rufin lantarki.

Rashin ƙarancin ruwa yana haɓaka aikin hana ruwa na bututun.

Yana da tsayayyar juriya mai kyau ga kullun cathodic kuma ya dace da fasahar kariya ta cathodic.

Juriya ga huda tushen shuka da yashwar ƙananan ƙwayoyin cuta, wanda ya dace da yanayin ƙasa daban-daban.

Yana da karfi mannewa zuwa karfe bututu da kuma tasiri mai kyau juriya, samar da ƙarin inji kariya.

A samar da tsari na 3PE anti-lalata karfe bututu hada da yashi ayukan iska mai ƙarfi da tsatsa kau a kan m surface na karfe bututu, preheating jiyya, epoxy foda spraying, m shafi, polyethylene Layer extrusion da iska, da dai sauransu.

Dalilan gazawar 3PE anti-lalata Layer na iya haɗawa da:

Maganin da ba daidai ba yana haifar da haɗin kai mai rauni tsakanin Layer anti-corrosion da matrix bututun ƙarfe.

Mummunan ingancin gini, kamar rashin isasshen zurfin ƙirar anka, yana shafar ƙarfin haɗin kai na Layer anti-lalata.

Gwaje-gwajen kariya na Cathodic sun nuna cewa rashin ƙarfi na kashe wutar lantarki na iya haifar da ɓarnar da keɓaɓɓu.

Matsayin fasaha na ma'aikatan gine-ginen kan layi yana da ƙasa, wanda ke rinjayar ingancin ginin.

Bincike a kan tsarin peeling na 3PE anti-lalata Layer ya nuna cewa thermal saura damuwa, cathode peeling, shigar azzakari cikin farji barbashi da lahani na anti-lalata bututu da kanta su ne manyan abubuwan da ke haifar da peeling.

Domin inganta juriya na peeling na 3PE anti-lalata Layer, da shafi tsari da kuma ingancin iko matakin bukatar da za a inganta. Har ila yau, ya kamata a yi nazari tare da nazarin abubuwan da ke tasiri na lalacewar Layer na lalata don samar da tushen ka'idar don ɗaukar matakan kariya masu tasiri.

3PE anti-lalata karfe bututu da m aikace-aikace al'amurra. Tare da karuwar aikin gina bututun mai da iskar gas, masana'antar hana lalata za ta haifar da lokacin ci gaba na zinariya. Bugu da ƙari, fasahar hana lalata 3PE kuma ta dace da bututun samar da ruwa na birane, yana taimakawa wajen inganta ingancin ruwa da kuma tsawaita rayuwar bututun.

A lokacin aikin ginawa da kiyayewa, wajibi ne a kula da lalacewa na 3PE anti-corrosion Layer da kuma amfani da hanyoyin gyaran gyare-gyaren da suka dace don tabbatar da mutunci da tasiri na gabaɗaya.

Gabaɗaya, an yi amfani da bututun hana lalata na waje 3PE sosai wajen gina bututun da aka binne a gida da waje saboda kyawawan kaddarorin su na rigakafin lalata da kuma tsawon rayuwar su.
