Yuav Ua Li Cas Xaiv Chlorinated Polyethylene (CPE) Kom Tsim Nyog

1. Piav qhia qhov yuav tsum tau muaj cov tshuaj chlorine
Cov tshuaj chlorine muaj 24% -30%: tsim nyog rau kev tsim cov khoom siv elastic (xws li cov txheej rwb thaiv tsev hlau, cov log tsheb).
Cov tshuaj chlorine muaj 35% -38%: Kev sib raug zoo heev nrog PVC, feem ntau siv rau kev hloov pauv ntawm cov khoom PVC tawv (xws li qhov rooj thiab qhov rai profile, cov kav dej).
Cov tshuaj chlorine> 40%: siv tau ua cov khoom siv yas lossis cov khoom tiv thaiv xeb thiab cov khoom siv hluav taws kub.
2. Soj ntsuam qhov hnyav ntawm cov molecular thiab hom khoom siv raw
CPE hnyav molecular siab: Nws muaj viscosity siab thiab tensile zog, uas yuav txo nws cov adhesion rau PVC.
Qhov hnyav molecular qis CPE: viscosity qis, flowability zoo, tsim rau cov xwm txheej nrog cov kev ua haujlwm siab.
Cov khoom siv polyethylene siab: Hom CPE no muaj kev tiv taus cua sov zoo dua thiab tsim nyog rau cov chaw siv kub siab.
3. Sib phim cov txheej txheem tsim khoom thiab cov kev cai ua tau zoo
Cov txheej txheem chlorine microbubble: Yog tias nws tsim nyog los txhim kho qhov ua tau zoo thiab kev sib xws ntawm cov tshuaj chlorination (xws li luv lub voj voog ntau lawm), cov khoom CPE siv cov txheej txheem tshuaj microbubble tuaj yeem raug xaiv ua ntej.
Daim ntawv thov ua npuas ncauj: Thaum siv rau PVC ua npuas ncauj, nws yog qhov tsim nyog los ua ke qhov sib piv ua npuas ncauj (2-3 zaug), qhov ceev (0.6-0.7 g / cm ³), thiab qhov nyuaj ntawm qhov chaw kom xaiv cov qauv CPE uas txhim kho lub zog yaj.
4. Kev sib raug zoo thiab kev sib koom tes ua haujlwm
Kev Sib Tw Nrog PVC: CPE nrog cov ntsiab lus chlorine ntawm 35% -38% muaj kev sib tw zoo tshaj plaws nrog PVC, uas tuaj yeem txhim kho kev tiv thaiv kev cuam tshuam yam tsis cuam tshuam rau kev ua haujlwm fluidity.
Kev tiv thaiv tshuaj lom neeg thiab hluav taws kub: CPE nrog cov tshuaj chlorine siab (> 50%) yog qhov tsim nyog rau kev tiv thaiv xeb thiab hluav taws kub (xws li cov kav dej tshuaj thiab cov ntaub ntawv tsim kho hluav taws).
5. Kev tswj xyuas zoo thiab kev tshuaj xyuas cov neeg muag khoom
Kev sib npaug ntawm cov khoom me me: Xyuas kom meej tias qhov loj ntawm CPE cov khoom me me raug tswj ntawm 0.1-200 μ m kom tsis txhob muaj kev sib sau ua ke lossis kev yaj tsis zoo vim yog cov khoom me me.
Hom thiab Kev Ntsuas: Xaiv cov neeg muag khoom uas muab daim ntawv pov thawj zoo tiav (xws li cov ntawv qhia txog kev ntsuas cov ntsiab lus chlorine, kev ntsuas kev ruaj khov thermal), thiab qhov tseem ceeb tshaj plaws yog xyuas kom meej tias lawv cov khoom ua haujlwm tau zoo hauv cov mis (xws li kev ceev ntawm kev ua kom yas, kev sib npaug ntawm lub cell). Bontecn Group Tuam Tshoj cov chlorinated polyethylene muab kev pabcuam thiab kev lees paub zoo rau koj.
6. Sib npaug tus nqi thiab kev ua tau zoo
Universal CPE: Cov khoom uas muaj cov tshuaj chlorine nruab nrab (35% -38%) muaj kev siv nyiaj ntau thiab tuaj yeem ua tau raws li feem ntau cov kev xav tau hloov kho PVC.
Cov xwm txheej siab kawg: Cov kev xav tau tshwj xeeb (xws li kev ua npuas dej tsawg heev thiab kev tiv taus kub siab) xav tau cov qauv tshwj xeeb, uas yuav ua rau kev nqis peev ntau ntxiv.
Kev xaus lus: Kev xaiv CPE yuav tsum yog raws li cov kev xav tau ntawm daim ntawv thov, phim cov xwm txheej ua haujlwm zoo los ntawm cov kev ntsuas xws li cov ntsiab lus chlorine, qhov hnyav molecular, kev sib raug zoo, thiab lwm yam, ua ke nrog kev lees paub cov txheej txheem ntau lawm thiab kev ntsuam xyuas kev tsim nyog ntawm cov neeg muab khoom, kom ua tiav qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi.
