iimveliso

PVC umbhobho wamandla izinto ekrwada,
I-PVC yombhobho wamandla, pvc resin yombhobho,

Umbhobho wamandla wePVC kunye nendlela yawo yokulungiselela ibandakanya ezi zinto zilandelayo:

100 polyvinyl chloride resin,
15 ~ 25 calcium carbonate,
5 ~ 10 titanium oxide,
4 ~ 8 isilungisi sempembelelo,
2 ~ 5 ukuzinzisa,
0.5 ~ 2 isithambiso,
2 ~ 4 sepiolite
I-3 ~ 8 i-ejenti edityanisiweyo ye-inorganic flame retardant, i-composite inorganic flame retardant evela kumhlaba onqabileyo we-hydroxide aluminiyam hydroxide Indlela yokulungiswa kwe-magnesium hydroxide kunye ne-zinc borate
Inkqubo yokuvelisa:
I-1) Yongeza i-calcium carbonate titanium oxide kwi-resin ye-POLYvinyl chloride kwaye uyixube ngesantya esiphezulu se-3-6min;2) Emva koko yongeza impembelelo ye-modifier stabilizer, i-lubricant sepiolite kunye ne-composite inorganic flame retardant kumxube.
Iqondo lokushisa lokuxuba liyi-100-110, kwaye ixesha lokuxuba liyi-10-15 imizuzu.Emva kokuba umxube uxutywe ngokulinganayo, umxube udluliselwa kumxube wokupholisa ngesantya esiphantsi se-40 ~ 50 kwimizuzu emi-3-5, kwaye ekugqibeleni kwi-conical twin screw extruder kwi-170 ~ 190 Ityhubhu yamandla yombane inokubuyiswa komlilo kwaye iimpawu zoomatshini

I-Polyvinyl Chloride (i-PVC) yi-resin ye-thermoplastic ehambelanayo eyenziwa yi-polymerization ye-vinyl chloride monomer.Ngenxa yomahluko wemathiriyeli ekrwada, kukho iindlela ezimbini zokwenza i-vinyl chloride monomer calcium carbide inkqubo kunye nenkqubo yepetroleum.I-Sinopec PVC ithatha inkqubo yokunqunyanyiswa kabini, ngokulandelelana kwiNkampani yeMichiza yeShin-Etsu kunye neNkampani ye-Oxy Vinyls yaseMelika.Imveliso inokumelana nokugqwala kweekhemikhali, ipropathi egqwesileyo yokugquma umbane kunye nokuzinza okuhle kweekhemikhali.Ngomxholo ophezulu we-chlorine, izinto eziphathekayo zinokutshatyalaliswa komlilo okulungileyo kunye neempawu zokuzicima.I-PVC kulula ukuyiqhuba nge-extrusion, isitofu sokubumba, i-calendering, ukubunjwa kokuvuthela, ukuxinzelela, ukubumba kunye nokubumba kwe-thermal, njl.

Isicelo

I-PVC yenye yezona zinto zisetyenziswa kakhulu kwi-thermoplastic resins.Ingasetyenziselwa ukwenza iimveliso ezinobunzima obuphezulu kunye namandla, njengemibhobho kunye nokufakelwa, iingcango zeprofayili, iifestile kunye namaphepha okupakisha.

Isenokwenza iimveliso ezithambileyo, ezinje ngeefilimu, amaphepha, iingcingo zombane kunye neentambo, iibhodi eziphantsi komhlaba kunye nesikhumba sokwenziwa, ngokongezwa kweeplasticizers.
