Qhov sib txawv tseem ceeb ntawm Hypalon thiab PVC yog Hypalon muaj ob pawg chlorine thiab chlorosulfonyl pawg, hos PVC tsuas muaj cov tshuaj chlorine xwb.
Hypalon yog cov khoom siv polymer uas muaj chlorosulfonated polyethylene (CSPE) thaum PVC yog cov khoom siv polymer muaj polyvinyl chloride. Zuag qhia tag nrho, Hypalon thiab PVC yog cov polymers uas muaj cov ntawv zoo sib xws.
Hypalon yog dab tsi?
Hypalon yog cov khoom siv polymer uas muaj chlorosulfonated polyethylene (CSPE). Nws yog ib hom khoom siv roj hmab hluavtaws uas muaj qhov tseem ceeb ntawm cov tshuaj. Ntxiv mus, cov khoom no qhia tau hais tias tsis kam mus rau kub heev thiab UV teeb. Hypalon yog ib yam khoom tsim los ntawm DuPont. Cov khoom no tuaj yeem tsim los ntawm kev kho polyethylene nrog kev sib xyaw ntawm chlorine thiab sulfur dioxide nyob rau hauv lub xub ntiag ntawm UV hluav taws xob.
Hypalon muaj txog 20-40% chlorine nrog rau ob peb feem pua ntawm chlorosulfonyl pawg. Cov chlorosulfonyl pawg no yog cov tshuaj reactive, thiab lawv muab cov ntaub ntawv no muaj peev xwm mus undergo vulcanization. Cov txheej txheem vulcanization tuaj yeem cuam tshuam loj rau lub cev ua haujlwm ntawm cov khoom ntawm cov khoom no.
Daim duab 01: Ib Lub Nkoj Nkoj
Thaum xav txog cov ntawv thov ntawm cov khoom siv Hypalon, feem ntau yog siv nrog cov khoom siv PVC hauv kev tsim cov nkoj loj thiab folding kayaks. Cov khoom no tseem ceeb heev raws li ib lub ply ru tsev membrane. Lwm daim ntawv thov tseem ceeb ntawm Hypalon yog kev siv cov khoom siv no los ua cov khoom siv hauv qab ntawm radomes, vim nws cov radar-pob tshab zoo.
YPVC yog dab tsi?
PVC yog ib qho polymer uas muaj polyvinyl chloride. Cov khoom no yog cov thermoplastic polymer ua los ntawm chloroethene monomers. PVC yog ib hom polymer, nrog rau polyethylene thiab polypropylene. Muaj ob pawg ntawm cov khoom siv PVC raws li daim ntawv nruj thiab daim ntawv hloov tau. Cov khoom siv PVC nruj yog qhov tseem ceeb hauv kev tsim kho kev xav tau, qhov hloov pauv PVC daim ntawv yog qhov tseem ceeb rau kev xaim thiab cables.
Daim duab 02: Cov kav dej PVC
Muaj peb kauj ruam tseem ceeb hauv kev tsim cov PVC. Thawj kauj ruam suav nrog kev hloov pauv ntawm ethane rau hauv 1, 2-dichloroethane. Cov kauj ruam no yog ua los ntawm chlorination. Cov kauj ruam thib ob ntawm PVC ntau lawm yog tawg ntawm 1, 2-dichloroethane rau hauv chloroethene, nrog rau kev tshem tawm ntawm HCl molecule. Qhov thib peb thiab kawg theem ntawm PVC ntau lawm yog cov txheej txheem polymerization ntawm chloroethene thiaj li yuav tsim PVC ntawm dawb radical polymerization txheej txheem.
PVC muaj ntau yam khoom tseem ceeb, suav nrog kev ua haujlwm siab thiab cov khoom siv zoo, tsis muaj cua sov ruaj khov, nplaim hluav taws xob zoo, hluav taws xob rwb thaiv tsev siab, thiab tshuaj lom neeg. Ntxiv mus, muaj ntau yam txiaj ntsig rau kev siv PVC. Piv txwv li, nws tau yooj yim muaj nyob rau hauv kev ua lag luam, thiab nws yog cov khoom pheej yig nrog lub zog tensile zoo. Cov khoom no kuj tiv taus cov tshuaj xws li acids thiab bases.
Qhov txawv ntawm Hypalon thiab PVC yog dab tsi?
Hypalon thiab PVC yog cov polymers muaj cov ntawv zoo sib xws. Qhov sib txawv tseem ceeb ntawm Hypalon thiab PVC yog tias Hypalon muaj ob pawg chlorine thiab chlorosulfonyl pawg, thaum PVC tsuas muaj chlorine pawg. Ntxiv mus, Hypalon yog tsim los ntawm kev kho polyethylene nrog ib tug sib tov ntawm chlorine thiab sulfur dioxide nyob rau hauv lub xub ntiag ntawm UV hluav taws xob thaum PVC yog ua los ntawm peb kauj ruam, nrog rau kev hloov ntawm ethane rau hauv 1, 2-dichloroethane, tawg ntawm 1, 2-dichloroethane rau hauv. chloroethene thiab cov txheej txheem polymerization ntawm chloroethene.
Hauv qab infographic tabulates qhov sib txawv tseem ceeb ntawm Hypalon thiab PVC.
Summary – Hypalon vs PVC
Hypalon yog cov khoom siv polymer uas muaj chlorosulfonated polyethylene. Lub sij hawm PVC stands rau polyvinyl chloride. Qhov sib txawv tseem ceeb ntawm Hypalon thiab PVC yog Hypalon muaj ob pawg chlorine thiab chlorosulfonyl pawg, hos PVC muaj chlorine pawg xwb.
