PVC K qiimaha 57
PVC K qiimaha 57,
Xabagta PVC ee loo isticmaalo in lagu soo saaro looxa xumbo,
Xabagta PVC ee leh qiimaha K ee 55-68 ayaa loo isticmaali karaa in lagu soo saaro xumbo adag, taas oo ah, alaabada PVC ee adag ee xumbo-hoose, taas oo ka duwan qiimaha K ee lagu bixiyay macluumaadka iyo buugaagta hore.Xirmooyinka PVC ee leh qiimaha K ee 69-77 ayaa lagu muujiyay inay ku habboon yihiin soo saarista xumbo jilicsan.Waxaa jira siyaabo badan oo loo soo saaro xabagta PVC, habka ganaaxa, habka emulsion iyo polymerization bulk ee xabagta PVC ayaa diyaar u ah alaabta ceeriin ee alaabta xumbo leh, sida caadiga ah ganaax iyo polymerization bulk ee xabagta PVC waa ku haboon.Copolymers-ka PVC iyo polymers-ka-jaridda (polymers granular) sidoo kale waxay leeyihiin hab-socod wanaagsan oo dhif iyo naadir ah ayaa loo istcimaali karaa sababo la xiriira qiimaha.
Polyvinyl Chloride, oo loo yaqaan PVC, waa mid ka mid ah noocyada caagagga warshadaha, wax soo saarka hadda waa kan labaad ee kaliya ee polyetylen.Polyvinyl chloride ayaa si weyn loogu isticmaalay warshadaha, beeraha iyo nolol maalmeedka.Polyvinyl chloride waa isku-dhismeed polymer ah oo lagu sameeyay koloride vinyl.Waa thermoplastic.Caddaan ama budo huruud ah oo fudud.Waxay ku milmi kartaa ketones, esters, tetrahydrofurans iyo hydrocarbons koloriin leh.Iska caabin kiimiko heer sare ah.Deganaansho kulayl xumo iyo caabbinta iftiinka, in ka badan 100 ℃ ama waqti dheer soo-gaadhista iftiinka qorraxdu waxay bilaabeen inay burburiyaan chloride hydrogen, wax soo saarka caaggu wuxuu u baahan yahay inuu ku daro xasiliye.Dahaarka korontada ayaa wanaagsan, ma guban doono.
Fasalka S-700Inta badan waxaa loo isticmaalaa in lagu soo saaro go'yaal hufan, waxaana lagu rogi karaa go'yaal adag iyo kuwo adag oo baakad ah, alaabta sagxadda, filim adag oo dahaarka ah (waraaqaha duubista nacnaca ama filimka sigaarka), iwm. Waxa kale oo lagu faafin karaa si adag ama aflaan adag, xaashi, ama bar qaabeysan oo aan joogto ahayn oo xirmo ah.Ama waa lagu duri karaa si loo sameeyo kala-goysyada, valves, qaybaha korontada, qalabka baabuurta iyo weelasha.
