Faahfaahinta alaabta
PVC waa erey la soo gaabiyay oo loogu talagalay chloride polyvinyl.Xabagta waa shay inta badan loo isticmaalo soo saarista caagagga iyo caagadaha.Xabagta PVC waa budo cad oo caadi ahaan loo isticmaalo in lagu soo saaro heerkulbeegyada.Waa walxo synthetic ah oo si weyn looga isticmaalo adduunka maanta.Polyvinyl chloride resin waxa uu leeyahay sifooyin aad u wanaagsan sida alaab cayriin oo badan, tignoolajiyada wax soo saarka ee bislaaday, qiimo jaban, iyo adeegsiyeedyo kala duwan.Way fududahay in la farsameeyo waxaana lagu farsamayn karaa qaabaynta, laminating, qaabaynta duritaanka, extrusion, calending, dharbaaxada qaabaynta iyo habab kale.Iyada oo leh astaamo jireed iyo kiimiko oo wanaagsan, waxaa si weyn loogu isticmaalaa warshadaha, dhismaha, beeraha, nolol maalmeedka, baakadaha, korontada, adeegyada dadweynaha, iyo beeraha kale.Xabagta PVC waxay guud ahaan leeyihiin iska caabin kiimiko oo sarreeya.Aad bay u xoog badan tahay oo u adkaysataa biyaha iyo naaxinta.Polyvinyl chloride resin (PVC) waxaa lagu farsamayn karaa baco kala duwan.PVC waa balaastiig khafiif ah, raqiis ah, oo deegaanka u wanaagsan.
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 alaabo jilicsan, sida filimaan, go'yaal, fiilooyinka korantada iyo fiilooyinka, sagxadaha sagxadaha iyo maqaarka synthetic, iyada oo lagu daro caagadaha.

Naqshadeynta Formula waxay ku salaysan tahay waxqabadka alaabta, alaabta ceeriin iyo kaabayaal ah, habka qaabeynta iyo qalabka.Tani waa shaqo adag oo caajis ah, si ay u noqoto mid ammaan ah, sida caadiga ah kaliya oo ku salaysan qaabka asalka ah ee qaan-gaarka ah iyadoo loo eegayo waayo-aragnimada dib-u-habeeynta yaryar, ka dibna iyada oo loo marayo imtixaanka si loo go'aamiyo xalka ugu fiican ee buuxinaya shuruudaha. Qoraagu wuxuu ku salaysan yahay qaabka albaabbada PVC ee caadiga ah iyo profiles Windows, isagoo ku daraya budada alwaax, wakiilka xumbo, wakiilka xumbo, wakiilka midabaynta, ka dibna sida waafaqsan imtixaanka orthogonal. si loo go'aamiyo cadadka alaabta ceeriin iyo kaaliyaha ee kala duwan.
Ku darida burka alwaaxdu waxay guud ahaan ka dhigi doontaa hantida qulqulka ee walxaha ka sii daraya. Iyada oo korodhka nuxurka budada alwaax, wakhtiga balaastiga ayaa la kordhiyaa, dheecaankuna wuxuu noqon doonaa mid hooseeya oo hooseeya. Haddii dareeraha maaddadu aad u liidato. , Budada alwaax waxaa lagu soo rogi doonaa xoog weyn oo xiirid ah, kordhinta wakhtiga degenaanshaha ee extruder, si ay budada alwaax waa sahlan tahay in la gubo, aan ku haboonayn extrusion; Taas bedelkeeda, haddii dareeraha waa mid aad u weyn si ay u sameeyaan cadaadis extrusion ku filan, waxa Waxa kale oo ay keeni doontaa cilladaha xoogga iyo cilladaha dusha sare ee alaabta. Sidaa darteed, habka extrusion, sifooyinka rheological ee nidaamka ayaa saameyn weyn ku leh habka mashiinnada iyo sifooyinka alaabta kama dambaysta ah. Shaxda 2 waxay muujinaysaa sifooyinka farsamaynta ee isku-dhafka leh ee kala duwan. cuntada qoriga ka kooban.
Sababtoo ah xajmiga qaybta weyn iyo cufnaanta yar yar ee budada alwaax ee loo isticmaalo imtixaanka, saamiga mugga ee budada budada ah ee nidaamka wuxuu kordhiyaa korodhka qadarka buuxinta, iyo awoodda xayeysiinta ee saliidaha, caagagga iyo wax-qabadka wax-qabadka. waa weyn.In kasta oo habka processing soo saari kartaa kulaylka weyn ee khilaafaad si loo dedejiyo plasticizer ah, laakiin kuma filna in ay ka soo kacdo ay sabab u plasticizer, wax lagu daro processing iyo xawaaraha balaastikada kale adsorbed si loo yareeyo saamaynta waqti plasticizer ah, si ay plasticizer daahiyaan. content weyn ee burka alwaax, ka processing badan AIDS nuugo, kaas oo kordhin doona wakhtiga plasticizing, liidata waxqabadka processing.The final go'aaminta doorashada ee content budada qoryo of 30.
Qalabka kale ee la isticmaalo waa 100 qaybood oo PVC ah, 3 qaybood oo ah sunta rasaasta tribasic, 1.5 qaybood dibasic sulfate, 0.5 qaybood oo ah stearate, 0.4 qaybood calcium stearate, 0.8 qaybood stearate, polyetylen wax..3 PCS, acrylic cool copolymer 5 PCS, polyetylen chlorated 6 PCS, CaCO30 PCS, AC xumbada wakiilka 0.9 PCS, ACR-530 5 PCS, birta jaalaha ah 0.31 PCS, bunni bir 0.15 PCS.
