HDPE roj yeeb nkab

Cov lus piav qhia luv luv:


Khoom Nthuav dav

HDPE roj yeeb nkab yog siv tau ruaj khov thiab muaj kev nyab xeeb, tsuas yog siv hauv kev tsim hluav taws xob hauv nroog.

 

Lub neej ntev

Kev siv nyab xeeb rau ntau dua 50 xyoo.

 

Ibility Ua kom yooj yim

Cov yeeb nkab PE muaj elongation thaum tawg ntau dua 500%. Nws yuav tsis tawg nyob rau hauv kev hloov chaw sib txawv xws li hauv av thiab av qeeg, thiab muaj kev nyab xeeb siab. Dabtsi yog khoov vojvoog (R≥15D), tsis tas yuav tsum yuav lub luj tshib pob qij txha, uas yooj yim rau kev tsim kho.

 

◎ Mob khaub thuas ua hauj

Txoj kev ncaj ncaj nthuav tawm txheej txheem ntawm cov yeeb nkab PE yog 1.5X10-4mm / mm ° C, thiab nws ntev yog yuav luag tsis cuam tshuam los ntawm kev hloov kub. Tsis muaj kev hloov lub cev tshwm sim txawm nyob rau -80 ° C. Nws yog qhov tshwj xeeb tshaj yog rau cov huab cua txias heev.

 

◎ Weldability

PE yeeb nkab tuaj yeem siv rau fusion hluav taws xob lossis kub sib txuas. Nws txoj kev sib txuas yog ua tiav, nruj thiab yuav tsis xau.

 

◎ Corrosion tsis kam

Raus hauv hydrochloric acid ntawm chav tsev kub. Hauv sulfuric acid (≤70%), nitric acid (%25%), phosphoric acid, hydrofluoric acid, complex acid (≤10%) thiab lwm yam kev daws teeb meem, PE kav dej tsis cuam tshuam.

 

. Alkali thiab cov roj ntsha inorganic

PE yeeb nkab muab tso rau hauv ntau yam lye, inorganic ntsev thiab dej hiav txwv ntawm 60 ℃, PE yeeb nkab yuav tsis xeb.

 

◎ Organic teeb meem

PE yeeb nkab tuaj yeem tiv taus cov kuab tshuaj organic zoo li hydrogen peroxide thiab roj av methyl nyob rau qhov kub thiab txias, thiab PE yeeb nkab yuav tsis xeb.

 

Ability Ua haujlwm tau zoo

PE yeeb nkab yog lub teeb ceeb thawj (tsuas yog 1/7 ntawm cov yeeb nkab steel) thiab muaj kev yoog raws. De16-De75 yeeb nkab tuaj yeem ua kom cov qhov txhab rau kev thauj mus los yooj yim thiab kev tsim kho.
