PVC jilicsan iyo PVC adag
PVC jilicsan iyo PVC adag,
baakad, guddi, Xabagta PVC ee qalabka dhismaha,
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,baakad, Korontada, adeegyada dadweynaha, iyo goobo 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, hargaha, fiilooyinka fiilooyinka, kabaha iyo ujeeddooyinka kale ee guud ee alaabta jilicsan, profiles, dhejisyada,guddis, duritaanka, samaynta, kabo-kabo, tuubo adag iyo alaabta qurxinta, dhalooyinka, go'yaasha, jadwalaynta, duritaanka adag iyo samaynta, 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
PVC waxaa loo qaybin karaa PVC jilicsan iyo PVC adag.Waxaa ka mid ah, xisaabaadka PVC adag ee qiyaastii 2/3 ee suuqa, iyo xisaabaadka PVC jilicsan ee 1/3.PVC jilicsan ayaa guud ahaan loo isticmaalaa sagxadaha, saqafka iyo sagxadaha maqaarka, laakiin sababtoo ah PVC jilicsan ayaa ka kooban jilciye (tani sidoo kale waa farqiga u dhexeeya PVC jilicsan iyo PVC adag), way fududahay in la jajabiyo oo ay adagtahay in la kaydiyo, sidaas awgeed baaxadda isticmaalka waa xaddidan.PVC adag kuma jiraan jilciye, sidaas darteed waxay leedahay dabacsanaan wanaagsan, sahlan in la qaabeeyo, ma fududa in la jajabiyo, aan sun ahayn, aan wasakhayn, waqti kaydinta dheer, sidaas darteed waxay leedahay horumar weyn iyo qiimaha codsiga.Hoos waxaa loo tixraacaa sida PVC.Nuxurka PVC-ga waa nooc ka mid ah filimka suufka vacuum, kaas oo loo isticmaalo baakadaha dusha sare ee baalal kala duwan, sidaas darteed waxaa sidoo kale loo yaqaan filimka qurxinta iyo filimka dhejiska, kaas oo loo isticmaalo qalabka dhismaha, baakadaha, daawada iyo warshado kale oo badan.Kuwaas waxaa ka mid ah, warshadaha qalabka dhismaha ayaa ah saamiga ugu badan ee 60%, oo ay ku xigto warshadaha baakadaha, waxaana jira codsiyo kale oo yar yar.
