Walaxda ceeriin ee looxa xumbo PVC
Alaabta ceeriin ee looxa xumbo PVC,
PVC resin SG5 loogu talagalay guddiga xumbo, PVC resin SG8 ee looxa xumbo,
Walaxda ceeriin ee looxa xumbo PVC
Xabagta: PVC guud ahaan waxay isticmaashaa nooca 8 resin, kaas oo leh xawaaraha gelation-ka degdega ah inta lagu jiro farsamaynta, heerkul aad u hooseeya, tayada badeecada deggan, iyo xakamaynta cufnaanta fudud.Sanadihii la soo dhaafay, warshado badan ayaa isku bedelay nooca 5.
Xasijiye: Xulashada xasiliyaha, iyadoo la tixgalinayo ilaalinta deegaanka iyo saameynta wanaagsan ee xasiliyaha dhulka dhifka ah ee la door bidaayo, laakiin sababta oo ah qiimaha aad u sarreeya, ee aan la dalacsiin, mustaqbalka oo leh shuruudaha ilaalinta deegaanka si loo kordhiyo, suuqa xasilinta dhulka naadir ayaa keeni doona rajooyin dhalaalaya.Calcium zinc stabilizer wuxuu leeyahay dhibaatada gubashada zinc iyo saameynta xasilloonida ayaa xoogaa liidata oo qaddarku waa ka yar yahay.Waqtigan xaadirka ah, xasilinta cusbada ugu badan ee loo isticmaalo ama sunta rasaasta, guddiga xumbo sababtoo ah qaybta iskutallaabta caaryada waa mid ballaaran, kanaalka qulqulka ayaa dheer iyo huruud-xumo-soo-saarka kulaylka kala-baxa, xasiliyaha ayaa looga baahan yahay inuu yeesho maaddo sare oo rasaas ah iyo saameyn xasilloon oo wanaagsan, haddii kale alaabtu waxay u nugul tahay dhibaatooyin kala duwan.
Wakiilka afuufaya: xulashada wakiilka afuufaya, wakiilka afuufaya AC ee habka burburku wuxuu sii daayaa kuleyl badan, si sahlan u hogaaminaya bartamaha qaybta jaalaha ah, taas oo u baahan qadar go'an oo ah wakiilka afuufka cad, kala-goysku wuxuu ciyaaraa doorka nuugista xad-dhaafka ah. tamarta kulaylka, waxay u baahan tahay tirada wakiilka afuufaya inay ahaato mid weyn, si loo gaaro xumbo isku mid ah oo aan lahayn godadka xumbo waaweyn.
Regulator: Xakamaynta xumbo-xakamaynta, iyada oo loo marayo sannado cilmi-baaris iyo horumarin iyo horumarin ah, tignoolajiyada habka ee xakamaynta xumbo-xakamaynta ACR ayaa noqonaysa mid aad iyo aad u qaan-gaar ah, tayada wax-qabadkuna waxay noqonaysaa mid aad u xasilloon.Marka loo eego dhumucda looxa xumboynta, xaashida waa in si degdeg ah loo caageeyo, looxa qaro weynina waa in la balaastigiyaa xal tartiib ah oo awood leh.
Saliidaha: Xulashada saliidaha waxay raacdaa mabda'a hore, dhexe iyo dambe ee saliidda, si alaabta ay u ilaaliyaan saliidaha marxaladaha oo dhan, una hoggaansamaan wax soo saarka xasilloon ee muddada dheer iyada oo aan wasakh lahayn.
Kaaliyeyaasha xumbo-samaynta: Si loo hagaajiyo tayada xumbo-saarka iyo qaab-dhismeedka xumbo, qadar yar oo kaabayaal xumbo ah ayaa lagu dari karaa wax soo saarka, iyo qadar yar oo aluminium silicate ah ayaa lagu dari karaa si loo yareeyo roobabka.
Pigments: Si loo gaaro saameyn aad u qurux badan, titanium dioxide iyo wakiilada nadiifinta fluorescent ayaa lagu dari karaa, iyo antioxidants iyo ultraviolet absorbers ayaa lagu dari karaa si loo hagaajiyo caabbinta cimilada.
Filler: Xulashada kaarboonka kaalshiyamka iftiinka ah waxay noqon kartaa, iyada oo aan la isticmaalin kalsiyum firfircoon, xulashada lambarka mesh sare.
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.
