PVC fais fab yeeb nkab raw khoom
PVC fais fab yeeb nkab raw khoom,
PVC rau lub cev muaj zog, pvc cob rau cov kav dej,
PVC hwj chim yeeb nkab thiab nws txoj kev npaj muaj xws li cov ntaub ntawv raw:
100 polyvinyl chloride cob,
15 ~ 25 calcium carbonate,
5 ~ 10 titanium oxide,
4 ~ 8 cuam tshuam hloov pauv,
2-5 stabilizer,
0.5 ~ 2 lub lis piam,
2 ~ 4 sepiolite
3 ~ 8 composite inorganic nplaim retardant tus neeg saib xyuas, puas inorganic nplaim retardant los ntawm tsawg lub ntiaj teb hydroxide aluminium hydroxide Kev npaj ntawm magnesium hydroxide thiab zinc borate
Txheej txheem ntau lawm:
1) Ntxiv calcium carbonate titanium oxide rau hauv POLYvinyl chloride resin thiab sib tov ntawm kev kub ceev rau 3-6min;2) Tom qab ntawd ntxiv qhov cuam tshuam kev hloov pauv stabilizer, roj nplua nyeem sepiolite thiab cov nplaim hluav taws xob tsis zoo rau hauv qhov sib xyaw.
Qhov sib tov kub yog 100-110, thiab lub sij hawm sib tov yog 10-15 feeb.Tom qab sib tov sib xyaw, qhov sib tov yog pauv mus rau lub tshuab cua txias ntawm qhov qis ntawm 40 ~ 50 rau 3-5 feeb, thiab thaum kawg mus rau hauv conical ntxaib ntsia hlau extruder ntawm 170 ~ 190 Lub raj fais fab muaj cov nplaim hluav taws zoo thiab mechanical zog
Polyvinyl Chloride (PVC) yog linear thermoplastic cob ua los ntawm polymerization ntawm vinyl chloride monomer.Vim yog qhov sib txawv ntawm cov khoom siv raw, muaj ob txoj hauv kev ntawm kev sib xyaw vinyl chloride monomer calcium carbide txheej txheem thiab cov txheej txheem roj av.Sinopec PVC tau txais ob txoj kev raug ncua, raws li Japanese Shin-Etsu Chemical Company thiab American Oxy Vinyls Company.Cov khoom muaj cov tshuaj zoo corrosion kuj, zoo heev hluav taws xob rwb thaiv tsev khoom thiab zoo tshuaj stability.Nrog cov ntsiab lus chlorine siab, cov khoom siv muaj hluav taws kub zoo thiab tua tus kheej.PVC yog yooj yim rau txheej txheem los ntawm extrusion, txhaj tshuaj molding, calendering, tshuab moulding, compressing, cam khwb cia molding thiab thermal molding, thiab lwm yam.
Daim ntawv thov
PVC yog ib qho ntawm cov khoom siv thermoplastic feem ntau siv.Nws tuaj yeem siv los ua cov khoom lag luam nrog lub siab tawv thiab lub zog, xws li cov kav dej thiab fittings, profiled qhov rooj, qhov rais thiab cov ntawv ntim.
Nws tseem tuaj yeem ua cov khoom muag muag, xws li cov yeeb yaj kiab, cov ntawv txheeb, cov xaim hluav taws xob thiab cov cables, cov ntaub pua tsev thiab cov tawv hluavtaws, los ntawm kev ntxiv cov yas yas.
