PVC Resin K Qiimaha 57-58 Loo isticmaalo soo saarista guddiga xumbo PVC, PVC S700,
Xabagta darajada K-57 ayaa guud ahaan loo isticmaalaa qaabaynta duritaanka sababtoo ah;sababtoo ah dhererkeeda silsiladda hoose (miisaanka kellika ah) muuqiisa ayaa ka hooseeya xargaha qiimaha K sare.Waxay leedahay barar dhinta oo ka sarreeya K- 67 kaas oo ka caawiya buuxinta dhinta iyo u wareejinta dhalaalka dusha caaryada una gudbisa alaabta.
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.
