Yuav ua li cas paub qhov txawv PE ntawm PVC, thiab dab tsi yog PE? PVC yog dab tsi? Hais txog cov cim qhia ntawm ob lub ntsiab lus no, cia peb mloog HDPE cov yeeb nkab fittings cov tuam txhab tsim khoom kom paub ntau ntxiv.
1. Kov txoj kev: nws mloog lubricating rau kov, thiab cov nplaim yog zoo li txheej ntawm ciab (chemically hu ua ciab), uas yog polyethylene zaj duab xis; Thiab tus thib ob zaj duab xis yog me ntsis nplaum rau qhov kov.
2. Co txoj kev: Lub suab ntawm co tes yog nkig, thiab nws yog cov yeeb yaj kiab polyethylene. Ib tug uas shakes nws nrog nws ob txhais tes thiab ua lub suab muaj tsawg yog ib tug sib sau ua ke.
3. Kev sib xyaw ua ke: ignite tam sim no thaum tua hluav taws, cov nplaim taws yog daj, thiab paraffin-zoo li roj kua paug thaum hlawv. Nws muaj qhov tsis hnov tsw ntawm lub tswm ciab hlawv, uas yog polyethylene zaj duab xis. Yog tias nws tsis yooj yim mus hlawv thiab yuav raug tua thaum nws tawm ntawm hluav taws, thaum nplaim taws tshwm ntsuab, nws yog ib qho kauv.
4. Cov Qauv Siv Tshuaj Tiv Thaiv: Siv cov zaj duab xis hauv dej, cov duab dhos polyethylene tuaj yeem sawv mus rau saum npoo tom qab nias. Ib tug uas tog rau hauv qab yog polyvinyl chloride zaj duab xis. Polyethylene, hais lig raws li PE, yog polymer muab tau los ntawm ethylene. Yooj yim rau xim, tshuaj lom neeg zoo, txias kuj, hluav taws xob tsis kam, thiab rwb thaiv hluav taws xob zoo. Nws yog qhov tsim nyog rau kev ua cov ntaub ntawv ntim khoom noj, ua rau cov khoom siv kho mob, khoom siv kho mob, thiab cov ntaub ntawv insulating rau kev lag luam hluav taws xob.
