Txoj kev yaj ntawm chlorinated polyethylene

Kev xaiv cov tshuaj yaj
Cov polyethylene chlorinated yaj tau hauv cov kuab tshuaj xws li toluene lossis xylene. Qhov kev yaj ntawm cov ester tau zoo dua los ntawm kev yaj cov esters xws li butyl acetate lossis PMA (propylene glycol methyl ether acetate). Cov kuab tshuaj polar xws li methanol thiab ethanol kuj tseem tuaj yeem cuam tshuam nrog cov chlorine atoms hauv cov chlorinated polyethylene molecules los txhawb lawv cov kev yaj. Qhov no yog vim tias cov chlorinated polyethylene molecules muaj cov chlorine atoms ntawm lawv cov saw hlau, thiab cov kuab tshuaj polar tuaj yeem cuam tshuam zoo nrog lawv.
Lwm yam uas cuam tshuam rau kev tshem tawm thiab kev ua haujlwm cuam tshuam
Qib Chlorination: Qhov siab dua qib chlorination ntawm chlorinated polyethylene, qhov siab dua nws cov solubility feem ntau nce raws li, yog li chlorinated polyethylene nrog qib chlorination siab yuav yooj yim dua rau yaj.
Kub: Feem ntau hais lus, thaum qhov kub nce ntxiv, qhov solubility ntawm chlorinated polyethylene hauv cov kuab tshuaj kuj nce ntxiv. Kev tsa qhov kub tuaj yeem pab ua kom nrawm dua qhov kev yaj, vim tias qhov kub siab tuaj yeem txhawb kev txav mus los ntawm cov saw hlau polymer, yog li ua kom nrawm dua kev sib cuam tshuam nrog cov kuab tshuaj. Txawm li cas los xij, kev nyab xeeb yuav tsum tau coj mus rau hauv tus account thaum lub sijhawm ua haujlwm kom tiv thaiv kev raug mob xws li kub hnyiab (saib qhov cuam tshuam ntawm qhov kub rau kev yaj ntawm cov khoom siv polymer zoo sib xws xws li polyvinyl cawv).
Kev sib xyaw (saib qhov kev ua haujlwm thaum yaj cov khoom zoo sib xws): Txawm hais tias lub luag haujlwm ntawm kev sib xyaw thaum lub sijhawm yaj ntawm chlorinated polyethylene tsis tau hais meej meej, los ntawm qhov kev xav ntawm kev yaj ntawm cov khoom polymer zoo sib xws, kev sib xyaw pab txhawb kev sib xyaw nrog cov kuab tshuaj, txo qhov sib txawv ntawm cov concentration hauv zos, thiab ua kom cov txheej txheem yaj sai dua. Thaum ntxiv cov hmoov chlorinated polyethylene rau cov kuab tshuaj, kev sib xyaw tuaj yeem pib ua tib lub sijhawm los txhawb kev yaj.
Lub sijhawm yaj: Yuav kom paub tseeb tias cov polyethylene chlorinated yaj tag, yuav tsum muaj sijhawm txaus, ib yam li polyvinyl cawv yuav tsum muaj sijhawm txaus rau kev yaj. Txawm li cas los xij, lub sijhawm tshwj xeeb yuav tsum tau txiav txim siab raws li ntau yam xws li qhov ntau npaum li cas ntawm chlorinated polyethylene, qhov ntau ntawm cov kuab tshuaj, thiab qhov kub.
