Qalabka ceeriin ee soo saarida tuubooyinka PVC
Qalabka ceeriin ee soo saarida tuubooyinka PVC,
Xabagta PVC, PVC si ay u soo saaraan tuubooyinka,
S-1000 xabagta polyvinyl chloride waxaa lagu soo saaraa habka polymerization hakinta iyadoo la isticmaalayo monomer vinyl chloride sida walxo ceeriin ah.Waa nooc ka mid ah isku dhafka polymer oo leh cufnaanta qaraabada ah ee 1.35 ~ 1.40.Barta dhalaalkeedu waa qiyaastii 70 ~ 85 ℃.Dejinta kulaylka liidata iyo caabbinta iftiinka, in ka badan 100 ℃ ama waqti dheer qorraxda hoosteeda chloride hydrogen waxay bilaabataa inay burburto, wax soo saarka caaga ah wuxuu u baahan yahay inuu ku daro xasiliyayaal.Alaabta waa in lagu kaydiyaa bakhaar qallalan oo hawo leh.Marka loo eego qaddarka balaastiigga, jilicsanaanta caagga ah waa la hagaajin karaa, iyo xajinta koollada waxaa lagu heli karaa polymerization emulsion.
Fasalka S-1000 waxaa loo isticmaali karaa in lagu soo saaro filim jilicsan, xaashida, maqaar la sameeyay, tuubooyin, baararka qaabaysan, hooska, tuubooyinka ilaalinta fiilada, filimka baakadaha, keligood iyo alaabo kale oo jilicsan.

Tuubooyinka PVC-ga waxaa lagu soo saaray extrusion of PVC wax ceeriin ah, iyo guud ahaan raac tallaabooyinka la mid ah hawlaha dhuumaha extrusion caadiga ah:
1. Quudinta budada cayriin ee loo yaqaan 'resin and filler' oo la geliyo fiilada mataanaha ee PVC;
2. Ku dhalaalidda iyo kuleylinta meelo badan oo ka baxsan;
3. Ka soo bixida dhinta si ay u qaabeeyaan tuubo;
4. Qaboojinta tuubada qaabaysan (adigoo ku buufinaya biyaha tuubada);iyo
5. Goynta tuubooyinka PVC ilaa dhererka la rabo.
Alaabta ceeriin ee soo saarta tubooyinka PVC waa resin iyo buuxin (badanaa calcium carbonate, ama inta badan loo yaqaan dhagaxyada).Isku darka caadiga ah waa 1 kiiloogaraam (kg) oo resin ah oo leh 1 kiiloogaraam oo buuxin ah.Nidaamyada wax soo saarka ayaa inta badan si toos ah u shaqeeya, iyada oo shaqaaluhu ay quudinayaan alaabta ceeriin bilowga habka, kormeerka heerkulka habka iyo hubinta alaabta ugu dambeysa ee cilladaha muuqda ka hor inta aan la xirin oo loo dirin macaamiisha.Dhammaan shaqaaluhu waa la tababaray oo awood u leh inay si karti leh u qabtaan dhammaan hawlahan.Qalabka ugu muhiimsan ee wax soo saarka tuubooyinka PVC waa walxo budada ah oo loo yaqaan 'PVC resin'.
