Hordhac
PVC waxay u adeegtaa sidii caag caalami ah oo leh waxsoosaarka ugu weyn iyo baaxadda codsiga ballaaran ee adduunka.Waxaa si weyn looga faa'iidaystay dhinacyada sida qalabka dhismaha, alaabta warshadaha, tuubooyinka maalin kasta la isticmaalo, shaabadeynta alaabta, fiilooyinka, iwm. PVC muujinaysaa siyaalo badan oo heer sare ah codsiga ballaaran ee labada qaybood ee warshadaha iyo madaniga ah.Si kastaba ha noqotee, resin PVC waxaa iska leh walxo jajaban.Marxaladdeeda muraayadda ah ee joogtada ah kama hortegi karto balaadhinta ba'an ee dildilaaca walaaca iyo ugu dambeyntii waxay abuurtaa daldaloolo iyo dillaac dillaacsan.Sidaa darteed, maaddada noocan oo kale ah waxay muujinaysaa iska caabin xun oo xun.Si kastaba ha ahaatee, cilladaan waxaa lagaga gudbi karaa iyada oo lagu daro wax ka beddelka saamaynta ee agabka PVC inta lagu jiro habka wax-soo-saarka iyo qaabaynta.
Wax-ka-beddelayaasha saamaynta wanaagsan waa in lagu muujiyaa waxyaabaha soo socda:
(1) Heerkul aad u hooseeya Tg;
(2) Iswaafajinta wax ka beddelka saamaynta laftiisa oo leh resin PVC;
(3) U dhigma viscosity ee wax ka beddelayaasha saamaynta leh PVC;
(4) Ma jiro wax saameyn ah oo muuqda oo muuqda oo ku saabsan sifooyinka muuqda iyo sifooyinka jireed iyo farsamada ee PVC;
(5) Iska caabin cimilo wanaagsan oo u dhinta hantida bararka.
Saamaynta guud ee wax ka beddelka PVC-ga adag waxay inta badan dabooshaa polyetylen koloriin leh (CPE), acrylate (ACR), ethylene-vinyl acetate copolymer (EVA), methyl methacrylate-butadiene-styrene ternary graft copolymer (MBS) iyo acrylonitrile-butadiene-styrene (BSApoly). ).Waxaa ka mid ah, beddelka saamaynta polyetylen-ka koloriin leh ayaa si weyn looga dabaqay Shiinaha iyo acrylate sidoo kale waa la sii kordhayaa sababtoo ah sifooyinkeeda ugu fiican.Waxay noqotay walaac guud sida loo hagaajiyo iska caabbinta saamaynta iyo in la fududeeyo extrusion caag ah.
Alaabtayada AIM ADX-600 waxay bedeli kartaa CPE iyo MBS.Waxay si weyn u wanaajin kartaa dareeraha iyo qallafsanaanta kulaylka ee PVC dhalaalaysa sidaas awgeedna waxay fududeyn kartaa caagagga PVC.Alaabooyinka natiijadu waxay muujinayaan awood saameyn sare leh iyo iska caabin cimilo oo wanaagsan, xasillooni iyo hanti farsamaysan oo leh dusha sare ee siman, qurux badan oo dhalaalaya.Marka xigta, waxaan ku falanqeynay ACR, CPE iyo MBS dhinacyada soo socda.
I. Farsamaynta Toughing by PVC Saamaynta wax ka beddelka
Polyethylene Chlorinated (CPE) waxay u adeegtaa sida unugyo toosan oo ku kala firirsan matrix PVC qaab shabakadeed.Mabda'a iska caabinta saameyntu waa in la sameeyo shabakad laastiig ah oo ku jirta walxaha matrix PVC si looga hortago saameynta dibadda.Shabakaddan oo kale waxay u nugul tahay in ay ku beddelato xoogga xajinta.Tani waxay kicin doontaa siibitaanka xiiran ee isku dhafka xagal 30 ° ilaa 45 ° ka soo jeeda jihada xajinta, sidaas darteed samaynta xadhig xiiran, nuugaya qadar badan oo tamar qallafsan, iyo kor u qaadida adkeynta nidaamka isku dhafka.Isbeddelka wax-soo-saarka walbahaarka ee walxaha hoos yimaada xoogga dibadda ayaa lagu muujiyay tirooyinka soo socda.
ACR iyo MBS waxay ka tirsan yihiin nooc ka mid ah "core-shell" wax ka beddelka saamaynta koobiyerka.Xuduntiisu waxa ay u adeegtaa sidii elastomer-ku-xiran hoose oo iskutallaabta ah, kaas oo door muhiim ah ka ciyaara kobcinta adkaysiga iyo iska caabinta saamaynta.Qolfkeedu wuxuu u adeegaa sidii polymer-molecular-sare leh oo leh heerkul sare oo vitrification, kaas oo doorarka ugu muhiimsan ka ciyaara ilaalinta xudunta caagga ah iyo hagaajinta ku-habboonaanta PVC.Qaybaha wax ka beddelka ee noocaan ah way fududahay in la kala saaro waxaana si siman loogu kala firdhi karaa matrix PVC si loo sameeyo qaab-dhismeedka "jasiiradda badda".Marka maaddadu ay ku xiran tahay saameynta dibadda, qaybaha caagga ah ee moodeelka hooseeya waxay u nugul yihiin qallafsanaan.Isla mar ahaantaana, isku-xidhka iyo daloolka ayaa la sameeyay sida maaddadu ay ku socoto isbeddelka PVC oo leh modules sare.Haddii godadkaas la sameeyay si ku filan, lakabka matrixka ee u dhexeeya qaybo caag ah ayaa soo saari kara oo kor u qaadi kara adkaysiga walxaha.Mabda'a u adkaysta saamaynta ayaa lagu muujiyay sawirka hoose.
CPE, ACR iyo MBS waxay muujiyaan dareenka kala duwan ee xoogga mishiinada sababtoo ah farsamooyinkooda adag ee kala duwan.Inta lagu jiro habaynta, qaybaha ACR iyo MBS waxaa lagu qaybiyaa shaxanka PVC iyada oo loo marayo ficil xiirid, samaynta qaab-dhismeedka "jasiirad-badeed" oo sidaas awgeed kor u qaadaya adkeynta walxaha.Xataa haddii awoodda habayntu ay sii korodho, qaab-dhismeedkani si sahal ah uma dhimi doono.Saamaynta adag ee ugu fiican ayaa la buuxin karaa oo keliya sida beddelka CPE iyo PVC ayaa lagu dhex daray qaab-dhismeedka shabakad kaas oo daboolaya qaybaha PVC ee aasaasiga ah.Si kastaba ha ahaatee, qaab-dhismeedka shabakadan si fudud ayaa loo jabin karaa iyadoo ay ugu wacan tahay isbeddelada ku yimaadda xoojinta habaynta.Sidaa darteed, waxay xasaasi u tahay xoojinta farsamaynta waxayna khuseysaa kala duwanaansho cidhiidhi ah.

4.Processing Tallaabooyinka
Jaantuska hoose wuxuu muujinayaa qalooca rheological.Khadka cas: ADX-600/3phr+CPE/3ph;khad buluug ah: CPE/9phr
Hirarka dheelitirka ee labadu asal ahaan waa isku mid, balaastikada walxaha ay wax ka beddeleen ADX-600/3PHr +CPE/3PHR ayaa xoogaa gaabis ah laakiin gacanta ayaa lagu hayaa marka loo eego shaxanka.Sidaa darteed, marka la eego habaynta, 3 qiyaasood ADX-600 oo lagu daray 3 qiyaasood oo CPE ah ayaa bedeli kara isticmaalka 9 qiyaasood ee CPE.
III.Gabagabadii
Marka la barbardhigo ADX-600 AIM iyo CPE iyo MBS ee qalabka farsamada iyo habdhaqanka farsamaynta, gabagabada soo socota ayaa lagu soo qaatay falanqayn ujeedo ah in 3 qiyaasood ADX-600 oo lagu daray 3 qiyaasood oo CPE ah ay bedeli karaan isticmaalka 9 qiyaasood ee CPE .ADX-600 AIM waxay muujinaysaa waxqabad dhammaystiran oo ka sii wanaagsan, kuwaas oo alaabooyinkooda ka soo baxa ay muujinayaan waxqabad wanaagsan iyo waxqabad kharash-ool ah oo sarreeya.
ADC-600 AIM waxa iska leh copolymer acrylate ah oo leh qaab dhismeed xudun u ah qolof.ACR waxa ay muujisaa sida ugu wanaagsan ee u adkaysiga cimiladu, xasiloonida kulaylka iyo saamiga qiimaha waxqabadka marka loo eego MBS sababtoo ah kii hore kuma jiro dammaanad labanlaab ah.Intaa waxaa dheer, ACR waxay sidoo kale soo bandhigaysaa faa'iidooyinka kala duwan ee processing ballaaran, xawaaraha extrusion degdeg ah, xakamaynta fudud, iwm Inta badan waxaa lagu dabaqaa galay alaabta PVC adag iyo semi-adag, gaar ahaan qalabka dhismaha kiimikada iyo alaabta dibadda, sida profiles, tuubooyinka. tuubooyinka, looxyada, alaabta xumbo, iwm. Waxay u adeegtaa sida nooc ka mid ah wax ka beddelka saamaynta leh qiyaas weyn oo hadda iyo mustaqbalka koritaanka weyn ee mustaqbalka.
