PVC simba pombi mbishi zvinhu
PVC simba pombi mbishi zvinhu,
PVC yemagetsi pombi, pvc resin yepombi,
PVC pombi yemagetsi uye nzira yekugadzirira inosanganisira zvinotevera zvigadzirwa:
100 polyvinyl chloride resin,
15-25 calcium carbonate,
5-10 titanium oxide,
4 ~ 8 kukanganisa kugadzirisa,
2 ~ 5 stabilizer,
0.5 ~ 2 lubricant,
2 ~ 4 sepiolite
3 ~ 8 composite inorganic flame retardant agent, composite inorganic flame retardant kubva isingawanzo hydroxide aruminiyamu hydroxide Nzira yekugadzira magnesium hydroxide uye zinc borate
Nzira yekugadzira:
1) Wedzera calcium carbonate titanium oxide muPOLYvinyl chloride resin uye sanganisa nekumhanya kwe3-6min;2) Wobva wawedzera iyo inokanganisa modifier stabilizer, lubricant sepiolite uye composite inorganic flame retardant mumusanganiswa.
Iko kusanganiswa kwekushisa ndeye 100-110, uye nguva yekusanganiswa ndeye 10-15 maminitsi.Mushure mekunge musanganiswa wasanganiswa zvakaenzana, musanganiswa unoendeswa kumuvhenganisi wekutonhora nekumhanya kwakaderera kwe40 ~ 50 kwemaminetsi matatu-5, uye pakupedzisira mune conical twin screw extruder pa170 ~ 190 Iyo yemagetsi chubhu ine yakanaka kunonoka kwemoto uye. mechanical properties
Polyvinyl Chloride (PVC) iine mutsara thermoplastic resin inogadzirwa ne polymerization yevinyl chloride monomer.Nekuda kwekusiyana kwezvinhu zvakabikwa, kune nzira mbiri dzekugadzira vinyl chloride monomer calcium carbide process uye petroleum process.Sinopec PVC inotora maitiro maviri ekumisa, zvichiteerana kubva kuJapan Shin-Etsu Chemical Company neAmerican Oxy Vinyls Company.Chigadzirwa chine yakanaka makemikari corrosion kuramba, yakanakisa magetsi ekudzivirira zvivakwa uye yakanaka kugadzikana kwemakemikari.Iine yakakwira chlorine yemukati, iyo nyaya ine yakanaka retardance yemoto uye yekudzima-inodzima zvinhu.PVC iri nyore kugadzirisa ne extrusion, jekiseni kuumba, calendering, kuvhuvhuta kuumbwa, compressing, kuumbwa kuumbwa uye kuumbwa kwekupisa, nezvimwe.
Application
PVC ndeimwe yeanonyanya kushandiswa thermoplastic resins.Inogona kushandiswa kugadzira zvigadzirwa zvine kuomarara kwepamusoro uye kusimba, senge pombi uye zvishongedzo, magonhi ane profiled, mahwindo uye mapepa ekurongedza.
Inogonawo kugadzira zvigadzirwa zvakapfava, senge mafirimu, mashizha, waya dzemagetsi netambo, floorboards uye synthetic dehwe, nekuwedzera kweplasticizers.
