Xabagta PVC ee fiilada
Xabagta PVC ee fiilada,
Qalabka Cable ee PVC, Qalabka Cayriinka ee PVC Cable, PVC ee Xargaha Korontada, Xabagta PVC ee daboolka fiilada,
PVC sababtoo ah waxay leedahay wax qabad wanaagsan oo jireed, kiimiko, koronto, ololka ololka, 1930-meeyadii iyo 40-meeyadii, ajnabigu wuxuu bilaabay inuu isticmaalo PVC jilicsan sida walxaha dahaarka ee fiilada, horumarinta iyo codsiga qalabka fiilada PVC ee waddankeena ayaa bilaabay 1950-meeyadii.Iyada oo la wanaajinayo awoodda wax-soo-saarka ee xabagta PVC, balaastiigga iyo waxyaabaha lagu daro warshadaha iyo kor u qaadista iyo adeegsiga noocyo cusub, warshadaha fiilada ayaa leh tayo tayo leh.
Qarnigii 21aad, iyadoo kor loo qaaday wacyiga deegaanka ee bini'aadamka, dadkuna ay u fiirsadaan caafimaadkooda, arrimaha deegaanku waxay noqdeen kuwa diiradda saaraya bulshada bini'aadamka.Wadamo badan, gobolo iyo ururo ayaa dejiyay heerar iyo xeerar adag si loo xaddido isticmaalka walxaha waxyeelada leh, gaar ahaan RolS iyo xeerarka REACH.Raadinta habab cusub iyo habab cusub, hagaajinta heerka isticmaalka kheyraadka, la qabsiga shuruudaha sharciyada ilaalinta deegaanka iyo xeerarka, ilaalinta deegaanka ee qalabka fiilada PVC ayaa soo baxay xilligan, oo si dhakhso ah u noqo mid ka mid ah mawduucyada hadda jira horumarinta qalabka fiilada PVC. .
Isbeddelka sii kordhaya iyo ballaarinta baahida suuqa ee fiilooyinka iyo fiilooyinka (oo loo yaqaan fiilada), iyo sidoo kale daraasad qoto-dheer oo lagu daro waxyaabo cusub oo kala duwan (sida waxyaabaha lagu daro ololka, xakamaynta qiiqa), waxay kor u qaadaan dhiirrigelinta iyo adeegsiga cusub teknoolajiyada, alaabta cusub iyo alaabta cusub ee alaabta PVC.In badan oo ka mid ah walxaha dabiiciga ah (sida caag, caag) oo loo isticmaalo warshadaha fiilooyinka, qadarka fiilada PVC waa walxaha ugu horreeya ee dabiiciga ah ee waddankeena.
Polymerka-molecular-ku-sare ee heerkulbeegga ah ee uu sameeyay polymerization-ka joojinta ee monomer-ka vinyl chloride.Qaabka molecular:- (CH2 – CHCl) n – (N: degree of polymerization, N= 590 ~ 1500).Waa alaabta ceeriin ee ugu ballaaran ee loo isticmaalo wax soo saarka caagga ah.Waxay leedahay xasillooni kiimikaad oo wanaagsan, iska caabbinta daxalka iyo iska caabinta biyaha.
