Qhov sib txawv ntawm PVC thiab PE

Polyvinyl chloride(PVC)yog ib qho pib ntawm vinyl chloride monomer nyob rau hauv peroxide, azo compound, thiab lwm yam los yog nyob rau hauv qhov kev txiav txim ntawm lub teeb thiab kub raws li lub mechanism ntawm dawb radical polymerization polymerization polymer.

Polyethylene(PE)yog ib qho thermoplastic cob uas tsim los ntawm polymerization ntawm ethylene. Hauv kev lag luam, nws kuj suav nrog copolymer ntawm ethylene nrog me me ntawm alpha-olefin. Polyethylene odorless, tsis muaj tshuaj lom, zoo li siv quav ciab, muaj qhov tsis zoo ntawm qhov kub thiab txias (qhov siv qhov tsawg kawg nkaus tuaj yeem ncav cuag -100 ~ -70} degree), tshuaj lom neeg ruaj khov, tsis kam mus rau feem ntau cov kua qaub thiab alkali yaig (tsis resistant rau acid nrog oxidation zog). Insoluble nyob rau hauv cov kuab tshuaj nyob rau hauv chav tsev kub, tsis tshua muaj dej nqus, zoo hluav taws xob rwb thaiv tsev.

 

Dab tsi yog qhov txawv ntawm PVC thiab PE?
1. Lub zog: PE muaj lub zog siab thiab tawv, thiab tuaj yeem tiv taus qhov kev ntxhov siab loj, thaum PVC muaj zog tsawg thiab yooj yim tawg.
2. Ceev: Qhov ntom ntawm PE yog qis dua PVC, yog li PE yog sib dua.
3. Corrosion kuj: PE muaj corrosion kuj zoo, thiab nws muaj kev ruaj ntseg zoo rau feem ntau cov tshuaj thiab cov kuab tshuaj. PVC muaj corrosion kuj zoo rau qee cov tshuaj thiab cov kuab tshuaj.
4. Thermal stability: PE muaj qhov kub thiab txias tsis kam thiab tuaj yeem tswj kev ruaj ntseg ntawm qhov kub siab dua. Lub thermal stability ntawm PVC yog qhov tsis zoo thiab yooj yim rau deformed los ntawm tshav kub.

5. Machinability: PE muaj machinability zoo thiab tuaj yeem ua tau yooj yim los ntawm extrusion, tshuab molding thiab lwm yam txheej txheem. PVC kuj muaj cov txheej txheem zoo thiab siv dav hauv kev tsim khoom ntawm ntau yam khoom yas.
6. nplaim retardant: PVC muaj cov nplaim hluav taws zoo, tsis yooj yim rau hlawv, tuaj yeem siv los tsim cov khoom siv hluav taws xob. Cov nplaim retardancy ntawm PE tsis zoo thiab tsis haum rau kev tsim cov khoom siv hluav taws xob.
7. Transparency: PE feem ntau yog translucent lossis opaque, PVC tuaj yeem kho cov pob tshab raws li qhov xav tau, tuaj yeem ua cov khoom pob tshab lossis cov khoom translucent.

 

Dab tsi yog qhov txawv ntawm PVC thiab PE hauv daim ntawv thov?
1.PE feem ntau yog siv rau hauv cov khoom ntim, xws li cov hnab yas, cov hnab ntim khoom noj, lub raj mis yas, thiab lwm yam. Tsis tas li ntawd, PE kuj tau siv dav hauv cov kav dej hauv av hauv kev tsim vaj tsev, cov kav dej hauv cov dej txuag dej, thiab cov ntim hauv cov tshuaj. kev lag luam.
2.PVC yog dav siv hauv cov khoom siv hauv tsev, xws li cov plag tsev, phab ntsa panels, qhov rais thav duab, thiab lwm yam. Tsis tas li ntawd, PVC kuj tuaj yeem tsim cov hlau thiab cable rwb thaiv tsev, cov kav dej, cov hnab yas.

 

Yuav ua li cas paub qhov txawv ntawm PVC thiab PE?
1, Kov txoj kev: txhais tes xav tias lubricated, nto zoo li coated nrog ib txheej ntawm wax (tshuaj hu ua wax), uas yog ib tug tsis muaj tshuaj lom polyethylene zaj duab xis; Thiab PVC zaj duab xis xav tias me ntsis nplaum.
2.S co txoj kev: tes tuav lub suab nkig, yog non-toxic polyethylene zaj duab xis; Nrog tes tuav lub suab qis yog polyvinyl chloride zaj duab xis hnab yas.
3.Combustion txoj kev: nyob rau hauv cov ntaub ntawv ntawm hluav taws, cov nplaim yog daj, hlawv roj paraffin te. Thiab muaj ntxhiab tsw tswm ciab hlawv, yog non-toxic polyethylene zaj duab xis; Yog tias nws tsis yooj yim rau hlawv, nws raug tua los ntawm qhov hluav taws kub, thiab cov nplaim taws yog ntsuab rau cov hnab yas polyvinyl chloride zaj duab xis.
4.Immersion txoj kev: lub hnab yas yog immersed nyob rau hauv dej, thiab cov non-toxic polyethylene zaj duab xis uas tuaj yeem ntog tom qab nias rau hauv dej los ntawm tes; Nws yog ib lub hnab yas polyvinyl chloride zaj duab xis uas ntog rau hauv qab.

 

Cov ntsiab lus:Dab tsi yog qhov txawv ntawm pe thiab pvc? PE thiab PVC yog ob qho khoom siv yas, uas muaj cov khoom sib txawv thiab kev siv. PE muaj lub zog zoo, kub tsis kam thiab siab corrosion kuj. PVC muaj cov txheej txheem zoo, nplaim hluav taws xob thiab pob tshab. Nyob rau hauv cov nqe lus ntawm daim ntawv thov, PE feem ntau yog siv nyob rau hauv ntim cov ntaub ntawv thiab civil engineering, thaum PVC feem ntau yog siv nyob rau hauv cov ntaub ntawv siv thiab hlau thiab cable rwb thaiv tsev txheej manufacturing thiab lwm yam teb.
