Xabagta PVC ee xaashida laminateerka
Xabagta PVC ee xaashida laminate,
Xabagta PVC ee loo isticmaalo in lagu soo saaro xaashida laminate,
Laminates-yada PVC waa lakabyo lakabyo badan oo ku salaysan Poly Vinyl Chloride, oo lagu sameeyay isku-buufin waraaqo iyo caag ah oo cadaadis sare leh iyo heerkulka.Waxa loo isticmaalaa sida lakabka qurxinta ee dusha sare ee sagxadaha cayriin sida alwaax.
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.
