1, Taw qhia:
Cov khoom yog tag nrho cov acrylate PVC ua pab, uas yog tsuas yog siv rau nruj PVC nplooj ntawv, zaj duab xis, pellets, profiles, kav thiab yeeb fittings. Nws yog tshwj xeeb tshaj yog haum rau PVC pob tshab khoom.
2 、 Cov khoom siv lub cev yooj yim
| Qhov tshwm sim | Dawb ntws hmoov |
| Intrinsic viscosity (η) 25 ℃ | 2.5~3.2 / 2.8~3.5 |
| Particle loj (dhau tus nqi ntawm 40 mesh) | ≥98 |
| Volatile teeb meem (%) | ≤1.0 |
| Qhov ceev (g / cm3) | 0.3~0.5 |
3, Cov yam ntxwv ntawm daim ntawv thov
Qhov sib ntxiv ntawm cov khoom me me hauv cov txheej txheem nyuaj thiab semi-rigid PVC molding tuaj yeem txhawb cov gelation ntawm PVC, txhim kho cov kua dej ntawm cov yaj, ua kom yaj lub zog, thiab pom tseeb txhim kho qhov zoo ntawm cov khoom.
4 、 Kev siv cov khoom siv
Txhawb nqa plasticization
Ua kom lub zog melting
Daim ntawv, zaj duab xis, profiled bar, Foamed yeeb nkab, Foamed board, yeeb nkab haum
5. Cia, ntim thiab thauj
Cov khoom yog muab ntim rau hauv ib lub hnab yas thiab muab tso rau hauv ib lub hnab woven. Lub hnab txuas nrog daim ntawv pov thawj khoom. Sab nraum lub hnab ntim khoom yog cim nrog: cov cim lag luam, lub npe chaw tsim khoom, qhov hnyav hnyav thiab tus lej batch.
Cov khoom no yog cov hmoov tsis muaj tshuaj lom thiab tsis muaj corrosive, uas yog cov khoom tsis txaus ntshai. Nws yuav tsum raug kho raws li cov khoom tsis txaus ntshai thaum lub sijhawm thauj mus los, thiab yuav tsum nruj me ntsis tiv thaiv los ntawm kev raug thiab los nag.
Cov khoom no khaws cia rau hauv qhov chaw txias thiab qhov cua rau ib xyoos. Tom qab ib xyoos, yog tias tsis muaj qhov hloov pauv tom qab ntsuas kev ua haujlwm, nws tseem tuaj yeem siv tau.
