PVC S-700
PVC S-700,
xaashida hufan ee PVC,
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-700 waxaa inta badan loo isticmaalaa in lagu soo saaro jajabyo hufan, waxaana lagu cadaadin karaa jeex adag ama qayb adag ama xaashida baakad, alaabta sagxadda, filim adag oo dahaarka ah (waraaqaha duubista nacnaca ama filimka sigaarka), iwm. Waxa kale oo lagu sii dayn doonaa jeex adag ama qayb adag, xaashi, ama baararka aan caadiga ahayn ee xirmada.Ama waa lagu duri karaa si loo sameeyo kala-goysyada, valves, qaybaha korontada, qalabka baabuurta iyo weelasha.
