Xabagta PVC ee loo isticmaalo in lagu soo saaro WPC, Walxaha ceeriin ee wax soo saarka WPC.,
WPC waa nooc cusub oo ah walxo deegaanka u fican, kaas oo lagu qasay alwaax iyo balaastiig, oo leh qaab alwaax ah iyo adkeysi caag ah.Habka wax soo saarka ee WPC inta badan waxaa ka mid ah diyaarinta alaabta ceeriin, qaso, extrusion, qaboojinta, goynta iyo baakadaha.
Diyaarinta alaabta ceeriin waa talaabada ugu horeysa ee wax soo saarka WPC.Alaabta ceeriin ee WPC inta badan waxaa ka mid ah bur alwaax, balaastiig, wax lagu daro iyo wixii la mid ah.Waxaa ka mid ah, burka alwaaxdu waxay ka samaysan tahay alwaax ka dib markii la burburiyo, baaritaanka iyo hababka kale, iyo caaggu wuxuu ka samaysan yahay polyetylen, polypropylene iyo walxo kale oo caag ah.Waxyaalaha lagu daro waxaa ka mid ah waxyaabaha ilaaliya, antioxidants, pigments, iwm, oo loo isticmaalo in lagu wanaajiyo waxqabadka iyo quruxda WPC.
Isku darka waa habka isku darka burka alwaaxyada, balaastiigga iyo waxyaabaha lagu daro qayb gaar ah.Ujeedada isku darka waa in la sameeyo alaabta ceeriin ee kala duwan si buuxda loo isku daray si ay u sameeyaan isku-dhafka isku midka ah, oo diyaar u ah habka soo-baxa ee xiga.
Ka dib, extrusion waa habka lagu tuujiyo alaabta ceeriin ee isku dhafan iyada oo loo marayo extruder.Dab-damisku waxa uu kulayliyaa alaabta ceeriin ee isku dhafan heerkul gaar ah si uu u jilciyo, ka dibna waxa uu ka sii saaraa caaryada.Looxa alwaax-caag ah oo la soo saaray ayaa leh qaab iyo cabbir gaar ah, laakiin sidoo kale waxay u baahan tahay in la qaboojiyo oo la gooyo.
Kadibna, qaboojintu waa habka lagu dhejinayo WPC-ga la saaray ee qaboojinta qaboojinta dabiiciga ah.Ujeedada qaboojinta waa in si dhakhso ah loo qaboojiyo WPC, laga dhigo qaabkeeda iyo cabbirkeeda mid deggan, lagana fogaado dhibaatooyinka sida qallafsanaanta iyo dildilaaca.
Goynta iyo baakaynta waa habka goynta iyo baakaynta WPC la qaboojiyey.Goyntu waa in la gooyo looxa alwaax-caag ah si waafaqsan cabbir gaar ah, si ay u buuxiso shuruudaha macaamiisha.Baakayntu waa jarista looxa balaastikada ah ee baakadaha, si loo fududeeyo gaadiidka iyo iibinta.
Habka wax soo saarka ee WPC waxaa ka mid ah diyaarinta alaabta ceeriin, qaso, extrusion, qaboojinta, goynta iyo baakadaha.Xidhiidhiyayaashani waxay iska kaashadaan midba midka kale si loo dhamaystiro habka wax soo saarka ee WPC, siinta dadka deegaanka saaxiibtinimo, qurux badan iyo walxo cusub oo waara.
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.
