Sidee qalabka wax lagu farsameeyo ee PVC u horumariyaan waxqabadka saliidda?

Doorka qalabka wax ka qabashada ACR ee farsamaynta PVC waxaa inta badan laga muujiyaa kor u qaadista balaastikada, hagaajinta sifooyinka dhalaalka, kor u qaadida xasilloonida farsamaynta, hagaajinta tayada badeecada, iyo kor u qaadida la qabsiga habka gaarka ah.
1. Kor u qaadida balaastikada
ACR waxay la falgashaa silsiladaha molecular-ka PVC iyada oo loo marayo kooxaha polar-ka, iyadoo yareyneysa is-xoqidda walxaha dhexdooda, dardar-gelinta balaastikada dhalaalaysa, soo gaabinaysa waqtiga farsamaynta (sida ACR-201, taas oo yaraynaysa waqtiga balaastikada 40-60 ilbiriqsi), waxayna hoos u dhigi kartaa heerkulka balaastikada 10-20 ℃ (moodooyinka ay ku jiraan kooxaha aashitada carboxylic).
2. Hagaaji waxqabadka dhalaalka
Xoojinta xoogga dhalaalka: Silsiladaha molecular-ka ee dhaadheer waxay sameeyaan shabakad jireed oo isku xiran, taasoo kordhinaysa xoogga dhalaalka 300% (ACR-401), taasoo ka hortagaysa dillaaca dhalaalka ee dheeraadka ah (sida ifafaalaha maqaarka shark);
Hagaaji dareeraha: yaree dheellitirka dhalaalka 10-15% oo kor u qaad waxtarka buuxinta heerarka xiirashada sare.
3. Hagaajinta xasilloonida habaynta
Joojiya kulaylka maxalliga ah, kor u qaad heerkulka bilowga ee kala-baxa kulaylka PVC laga bilaabo 190 ℃ ilaa 210 ℃, yaree isbeddelka heerkulka dhalaalka, oo yaree wareegga 15-20% marka lagu daro saliidaha (ACR-530).
4. Hagaaji tayada badeecada
Ka saarista cilladaha dusha sare sida indhaha kalluunka iyo calaamadaha socodka, si weyn u hagaajinaya simanka (sida ceeryaamo <3%, dhalaalka ka sarreeya 90%); Kordhi adkaanta saameynta (5-10 jeer waxay kordhisaa xoogga saameynta heerkulka hooseeya) iyo iska caabbinta cimilada.
5. Taageer hababka gaarka ah
Goobta xumbo-samaynta: Hagaaji xoogga dhalaalka si aad u sameyso daloolada xumbada mid isku mid ah oo cufan;
Badeeco hufan: tusmada PVC ee iswaafajinaysa (ACR-Z30 haze <3%);
Goobta Caafimaadka: Yaree roobabka (moodooyinka ka kooban kooxaha aashitada carboxylic waxay yareeyaan sii deynta HCl 60%).
Moodooyin kala duwan ayaa ku habboon hababka gaarka ah: ACR-401 (kordhinta/rogidda) waxay xoojisaa xoogga dhalaalka, ACR-201 (qaabaynta duritaanka/afuufidda) waxay wanaajisaa socodka, ACR-530 waxay dheellitirtaa nidaamka saliidaynta.
