Xabagta PVC ee haragga synthetic, maqaar macmal ah,
PV C ee maqaarka synthetic, PVC ee maqaar macmal ah,
PVC waa erey la soo gaabiyay oo loogu talagalay chloride polyvinyl.Xabagta waa shay inta badan loo isticmaalo soo saarista caagagga iyo caagadaha.Xabagta PVC waa budo cad oo caadi ahaan loo isticmaalo in lagu soo saaro heerkulbeegyada.Waa walxo synthetic ah oo si weyn looga isticmaalo adduunka maanta.Polyvinyl chloride resin waxa uu leeyahay sifooyin aad u wanaagsan sida alaab cayriin oo badan, tignoolajiyada wax soo saarka ee bislaaday, qiimo jaban, iyo adeegsiyeedyo kala duwan.Way fududahay in la farsameeyo waxaana lagu farsamayn karaa qaabaynta, laminating, qaabaynta duritaanka, extrusion, calending, dharbaaxada qaabaynta iyo habab kale.Iyada oo leh astaamo jireed iyo kiimiko oo wanaagsan, waxaa si weyn loogu isticmaalaa warshadaha, dhismaha, beeraha, nolol maalmeedka, baakadaha, korontada, adeegyada dadweynaha, iyo beeraha kale.Xabagta PVC waxay guud ahaan leeyihiin iska caabin kiimiko oo sarreeya.Aad bay u xoog badan tahay oo u adkaysataa biyaha iyo naaxinta.Polyvinyl chloride resin (PVC) waxaa lagu farsamayn karaa baco kala duwan.PVC waa balaastiig khafiif ah, raqiis ah, oo deegaanka u wanaagsan.Pvc Resin waxaa loo isticmaali karaa tuubooyinka, daaqadaha daaqadaha, tuubooyinka, maqaarrada, fiilooyinka fiilooyinka, kabaha iyo ujeeddooyinka kale ee guud ee alaabta jilicsan, profiles, dhejisyada, muraayadaha, duritaanka, naqshadeynta, kabaha, tuubada adag iyo alaabta qurxinta, dhalooyinka, xaashida, jadwalka duritaan adag iyo qaabaynta iwm iyo qaybo kale.
Astaamaha
PVC waa mid ka mid ah resins thermoplastic ee ugu isticmaalka badan.Waxaa loo isticmaali karaa in lagu sameeyo alaab adag oo adag, sida tuubooyinka iyo qalabka wax lagu dhejiyo, albaabada muuqaalkooda leh, daaqadaha iyo baakadaha.Waxa kale oo ay samayn kartaa alaabo jilicsan, sida filimaan, go'yaal, fiilooyinka korantada iyo fiilooyinka, sagxadaha sagxadaha iyo maqaarka synthetic, iyada oo lagu daro caagadaha.

Codsiga
Maqaar macmal ah oo Polyvinyl chloride ah ayaa laga sameeyay resin PVC, balaastiigiyeyaasha, xasiliyayaasha, buuxinta, kaaliyeyaasha kale iyo saldhigga dharka iyada oo loo marayo farsamooyin kala duwan oo wax lagu sameeyo si loo sameeyo alaab caag u eg.
Xabagta PVC waa alaabta ceeriin ee ugu weyn ee maqaar macmal ah.Iyada oo ku xidhan habka wax-soo-saarka, resin-ka-joojinta ama resin-ka emulsion-ka ayaa inta badan la isticmaalaa.Habka wax soo saarka ee habka daahan wuxuu u baahan yahay in lagu sii diyaariyo plastisol, inta badan iyadoo la isticmaalayo resin emulsion.Habka wax soo saarka ee calending ama habka laminating wuxuu u baahan yahay in laga sameeyo filim ama xaashi, iyo xabagta la hakiyey ayaa la isticmaalaa.Sida caadiga ah maqaar macmal ah waxay qabataa nooca firidhsan qayb ka fiican oo ay diyaarisay habka polymerization emulsion ama habka polymerization hakinta.
Doorashada shahaadada polymerization waxaa lagu go'aamin karaa iyadoo loo eegayo shuruudaha waxqabadka iyo xaaladaha ka-hortagga maqaarka macmalka ah.Sababtoo ah celceliska celceliska polymerization of resin PVC ayaa saameyn weyn ku leh waxqabadka maqaarka macmalka ah, celceliska celceliska polymerization of resin PVC waa weyn yahay, badeecada PVC waxay leedahay barti wanaagsan, iftiin, viscosity sare, laakiin badeecada xumbo leh ayaa leh unugyo dhumuc weyn. iyo isku midnimo liidata;polymerization celceliska Alaabta PVC ee heerka hoose waxay leeyihiin daloolo aad u fiican, laakiin dabacsanaantoodu liidato.Darajada polymerization ee xabagta emulsion ee la isticmaalo guud ahaan waa 1000-1400, xabagta laaliddu waa 800-1200.
Maqaar macmal ah oo Polyvinyl chloride ah ayaa si weyn loogu isticmaalaa shandadyada iyo barkinta baabuurta.Shirkaddayadu waxay leedahay laba nooc oo ah K57 iyo K67 PVC resin budada sahayda, soo dhawoow si aad u iibsato.
