Xabagta PVC ee haragga synthetic
Xabagta PVC ee maqaarka synthetic,
PVC ee maqaarka synthetic,
Dharka maqaarka ee PVC wuxuu aad ugu eg yahay dharka maqaarka ee PU.Halkii laga heli lahaa polyurethane, dharka maqaarka ee PVC waxaa lagu sameeyaa iyadoo la isku darayo polyvinylchloride iyo xasiliyeyaasha (si loo ilaaliyo), caagagga (si loo jilciyo) iyo saliidaha (si loo sameeyo dabacsanaan), ka dibna lagu dabaqo alaabta aasaasiga ah.
Maqaarka PVC-ku-salaysan ayaa ah beddelka ugu weyn ee maqaarka dhabta ah.Waxaa la soo saaray iyadoo lagu beddelayo kooxda hydrogen oo lagu beddelayo kooxda chloride ee kooxda vinyl.Alaabtan ayaa markaa lagu daraa kiimikooyin si loo abuuro maqaar la isku daray.Waxyaabaha ugu weyn ee ceeriin ee loo isticmaalo habkan waa PVC.Maqaarka PVC-ku-salaysan wuxuu ahaa maqaarkii ugu horreeyay ee la sameeyay 1920-kii.Waxaa loo arkaa inay tahay xoog sare oo u adkaysata xaaladaha cimilada kala duwan.Waa shay si sahlan loo dayactiri karo oo nadiif ah, sidaas darteed aad ayaa looga doorbidaa warshadaha kala duwan.
Habka wax soo saarka maqaarka ee PVC
1.habka ugu horeeya waa habka calending.
marka ugu horaysa waa in aan isku qasnaa alaabta ceeriin ee PVC iyo midabka iwm, oo aan ka dhigno walxaha qaab adag.
2.ka dibna waxaan ku dhejinnay walxaha isku dhafan ee dharka, ilaa nidaamkan walxaha semi-dhammeeyay ee aan ugu yeerno qalabka aasaasiga ah.
sidaas darteed walxaha aasaasiga ah oo ay ku jiraan 2 lakab: lakabka pvc ee dusha sare iyo dhabarka waa dhar.
ka dibna alaabta saldhigga ah waxaa loo diri doonaa mishiinka xumbo, kaas oo ah xariiqa wax soo saarka dheer oo leh heerkul sare, walxaha isku dhafan ayaa halkan ku xumbeynaya, markaa pvc waxay noqon doontaa dhumuc weyn, dhumucda lakabka pvc waxay noqon kartaa labanlaab lakabka pvc.
xumbo ka dib, walxaha waxaa lagu qurxin doonaa texture, halkan waxaan u isticmaali rullaluistemadka leh texture on rullaluistemadka, waxaad u malayn kartaa sida caaryada ah, texture on rullaluistemadka waxaa loo wareejin doonaa dusha lakabka pvc, ka dibna waxaan ka heli kartaa kala duwan. texture.
ka dib waxaan samayn doonaa daaweynta dusha, sida hagaajinta midabka ama daabacaadda qaar ka mid ah sawirada dusha sare.
Hoos waxaa ku yaal qulqulka wax soo saarka ee maqaarka pvc
Astaamaha
PVC waa mid ka mid ah resins thermoplastic ee ugu isticmaalka badan.Waxaa loo isticmaali karaa in lagu sameeyo alaab adag oo adag, sida tuubooyinka iyo qalabka wax lagu dhejiyo, albaabada muuqaalkooda leh, daaqadaha iyo baakadaha.Waxa kale oo ay samayn kartaa alaab jilicsan, sida filimada, go'yaal, fiilooyinka korantada iyo fiilooyinka, sagxadaha dhulka iyomaqaar synthetic, iyada oo lagu daro balaastikada
