Kev faib tawm ntawm cov kav dej PE los ntawm cov chaw muag khoom

Ntawm tag nrho cov engineering plastics, HDPE yog thawj zaug ntawm cov yas hais txog kev hnav tsis kam thiab yog qhov muag pom. Qhov siab dua qhov hnyav molecular, cov khoom hnav-tiv taus ntau dua, txawm tias dhau ntau cov ntaub ntawv hlau (xws li carbon steel, stainless hlau, bronze, thiab lwm yam). Lub neej kev pab cuam nyob rau hauv muaj zog corrosion thiab siab hnav tej yam kev mob yog 4-6 lub sij hawm ntawm steel kav thiab 9 npaug ntawm zoo tib yam polyethylene; Thiab txhim kho cov khoom siv tau zoo los ntawm 20%. Cov nplaim retardant thiab anti-static zog yog qhov zoo thiab ua tau raws li tus qauv yuav tsum tau ua. Lub neej kev pabcuam hauv av tau tshaj 20 xyoo, nrog cov txiaj ntsig tseem ceeb ntawm kev lag luam, kev cuam tshuam kev cuam tshuam, hnav tsis kam, thiab cov teebmeem tseem ceeb dual.

PE kav dej rau cov dej phwj tuaj, tseem hu ua high-density polyethylene kav, los yog HDPE. Hom yeeb nkab no feem ntau siv los ua cov kav dej hauv nroog engineering, feem ntau hauv kev kho dej phwj hauv kev lag luam. Vim nws cov yam ntxwv ntawm kev hnav tsis kam, acid tsis kam, corrosion kuj, kub tsis kam, thiab kev kub siab tsis kam, nws tau maj mam hloov cov kav dej xws li cov kav hlau thiab cov kav dej cement hauv khw. Tshwj xeeb tshaj yog vim tias cov yeeb nkab no yog lub teeb yuag thiab yooj yim rau nruab thiab txav mus los, nws yog qhov kev xaiv ntawm cov khoom siv tshiab. Thaum cov neeg siv xaiv cov kav dej ua los ntawm cov khoom siv no, lawv yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus hauv qab no: 1. Kev xaiv cov khoom siv yeeb nkab yuav tsum tau ceev faj tshwj xeeb. Muaj ntau txhiab qib ntawm polyethylene raw cov ntaub ntawv, thiab muaj cov ntaub ntawv raw li tsawg li ob peb txhiab yuan ib tuj ntawm lub khw. Cov khoom tsim los ntawm cov khoom siv raw tsis tuaj yeem tsim kho, txwv tsis pub nws yuav ua rau poob loj heev. 2. Kev xaiv cov kav dej yuav tsum ua raws li cov neeg tsim khoom raug cai thiab cov kws tshaj lij. 3. Thaum xaiv yuav cov kav dej PE, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev tshuaj xyuas ntawm qhov chaw tsim khoom kom pom tias lawv muaj peev xwm tsim tau.

PE kav dej rau dej yog cov khoom siv hloov cov kav dej ib txwm siv thiab cov kav dej polyvinyl chloride haus. Cov kav dej yuav tsum tiv taus qee qhov siab, feem ntau yog siv PE resin nrog qhov hnyav molecular thiab cov khoom siv zoo, xws li HDPE resin. LDPE resin muaj lub zog tensile tsawg, tsis zoo siab tsis kam, tsis zoo rigidity, tsis muaj qhov ruaj khov thaum lub sij hawm molding thiab ua, thiab nws nyuaj rau kev sib txuas, ua rau nws tsis tsim nyog raws li cov khoom siv rau cov kav dej siab. Tab sis vim nws cov ntsuas kev nyiam huv siab, PE, tshwj xeeb tshaj yog HDPE resin, tau dhau los ua cov khoom siv los ua cov kav dej haus. HDPE resin muaj tsawg yaj viscosity, zoo flowability, thiab yog ib qho yooj yim rau txheej txheem, yog li qhov kev xaiv ntau yam rau nws melt index kuj kuj dav, feem ntau nrog MI ntawm 0.3-3g / 10min.

Shandong Kungang Hlau Technology Co., Ltd. muab PE kav txhua xyoo, thiab tuaj yeem khaws ntau yam tshwj xeeb thiab qauv hauv lub tsev rau khoom. Tau ntau xyoo, peb lub tuam txhab tau ua raws li lub hauv paus ntsiab lus ntawm "lub koob npe nrov, kev pabcuam, thiab kev ua haujlwm zoo yog lub neej" nyob rau hauv tus txheej txheem ntawm kev loj hlob sai nrog lub siab dawb paug. Peb tau tsim lub zog muaj zog, tsim lub hauv paus kev lag luam zoo, thiab ua rau ntau tus neeg koom tes hauv tsev thiab txawv teb chaws. tos ntsoov rau peb kev koom tes!
