A conical twin screw extruderni ubwoko bwa twin screw extruder ifite imigozi ibiri itondekanye muburyo bwa conic, ikanda yerekeza kumasohoro ya extruder. Igishushanyo gitanga kugabanuka gahoro gahoro ingano ya screw, bikaviramo umuvuduko mwinshi no guteranya neza. Extruder ya conic twin screw igizwe ahanini na screw ya barriel, sisitemu yo kohereza ibikoresho, kugaburira kwinshi, gusohora vacuum, gushyushya, gukonjesha no kugenzura amashanyarazi.
Impuzamugambi ya conin ikwirakwiza kubyara PVC ivuye mu ifu ivanze. PVC ni polymer ya thermoplastique ifite porogaramu zitandukanye mubikorwa bitandukanye, nk'ubwubatsi, gupakira, amashanyarazi, amamodoka, n'ubuvuzi. Ariko, PVC ntishobora guhuzwa nizindi polymers ninyongeramusaruro, kandi bisaba tekiniki zidasanzwe zo gutunganya kugirango ugere kubintu byifuzwa no gukora. Impuzamugambi ya conical irashobora gutanga ivangwa rya ngombwa, gushonga, devolatilisation, hamwe na homogenisation ya PVC ninyongera zayo muburyo bukomeza kandi bunoze.
Conical twin screw extruder nayo ni ibikoresho byihariye byo gukuramo ifu ya WPC. WPC igereranya ibiti-bya pulasitiki, ni ibikoresho bihuza fibre yimbaho cyangwa ifu yinkwi hamwe na polimoplastique, nka PVC, PE, PP, cyangwa PLA. WPC ifite ibyiza byibiti na plastiki, nkimbaraga nyinshi, kuramba, guhangana nikirere, hamwe no kongera gukoreshwa. Impuzamugambi ya conic irashobora gutunganya ifu ya WPC hamwe nibisohoka byinshi, gukora neza, hamwe nubuzima burebure.
Hamwe nibikoresho bitandukanye kandi byamanutse, ibyuma bisohora impanga birashobora kubyara ibicuruzwa bitandukanye bya PVC na WPC, nk'imiyoboro, igisenge, imyirondoro yidirishya, urupapuro, igorofa, na granules. Ibicuruzwa bifite imiterere, ingano, nibikorwa bitandukanye, kandi birashobora guhuza ibyifuzo bitandukanye byabakiriya nisoko.
Ibisobanuro
Inzira yo gukuramo ibice bibiri irashobora kugabanywamo ibice bine byingenzi: kugaburira, gushonga, devolatilisation, no gushiraho.
Kugaburira
Icyiciro cya mbere cya conical twin screw gukuramo ni kugaburira. Muri iki cyiciro, ibikoresho fatizo, nka poro ya PVC cyangwa WPC, nibindi byongeweho, nka stabilisateur, amavuta yo kwisiga, ibyuzuza, pigment, hamwe na modifiseri, byapimwe kandi bigaburirwa muri extruder nibikoresho bitandukanye byo kugaburira, nka screw augers, vibratory tray, gupima-umukandara, na pompe zo gutera. Igipimo cyo kugaburira nukuri nibintu byingenzi bigira ingaruka kumiterere no guhuza ibicuruzwa byanyuma. Ibikoresho fatizo birashobora kubanza kuvangwa no kugaburirwa, cyangwa gutandukana kandi bikurikiranye bikagerwaho muri extruder, bitewe nuburyo byakozwe nibicuruzwa byifuzwa.
Gushonga
Icyiciro cya kabiri cya conical twin screw gukuramo irashonga. Muri iki cyiciro, ibikoresho fatizo bitangwa, bigahunikwa, kandi bigashyukwa ninsinga zizunguruka hamwe nubushyuhe bwa barriel, hanyuma bigahinduka kuva mubintu bikomeye bikajya mumazi. Uburyo bwo gushonga burimo ingufu zumuriro nubukanishi, kandi bigaterwa numuvuduko wa screw, iboneza rya screw, ubushyuhe bwa barriel, nibintu bifatika. Uburyo bwo gushonga nabwo ni ingenzi mu gukwirakwiza no gukwirakwiza inyongeramusaruro muri materix ya polymer, no gutangiza imiti y’imiti, nko guhuza, gushushanya, cyangwa gutesha agaciro, bishobora kugaragara mu gushonga. Uburyo bwo gushonga bugomba kugenzurwa neza kugirango wirinde gushyuha cyane, kogosha cyane, cyangwa gushonga munsi yibikoresho, bishobora kuvamo ibicuruzwa bidahwitse nibikorwa.
Devolatilisation
Icyiciro cya gatatu cya conical twin screw gukuramo ni devolatilisation. Muri iki cyiciro, ibice bihindagurika, nkubushuhe, umwuka, monomers, ibishishwa, nibicuruzwa byangirika, bivanwa mumashanyarazi ushizemo icyuho ku byambu bya ventrale hafi ya barruder. Gahunda ya devolatilisation ningirakamaro mugutezimbere ubuziranenge bwibicuruzwa no gutekana, ndetse no kugabanya ingaruka z’ibidukikije ndetse n’ingaruka z’ubuzima ziterwa no gusohora. Igikorwa cya devolatilisation giterwa nigishushanyo mbonera, urwego rwa vacuum, gushonga kwijimye, nibiranga ibintu. Igikorwa cyo gusenya devolatilisation kigomba kunozwa kugirango kigere ku gukuraho bihagije ibirindiro bidateye ifuro ryinshi, umwuzure, cyangwa gushonga.
Gushiraho
Icyiciro cya kane nicyanyuma cya conical twin screw gukuramo ni gushiraho. Muri iki cyiciro, gushonga bisohoka binyuze mu rupfu cyangwa ifumbire igena imiterere nubunini bwibicuruzwa. Urupfu cyangwa ifumbire irashobora gushushanywa kubyara ibicuruzwa bitandukanye, nk'imiyoboro, imyirondoro, urupapuro, firime, cyangwa granules. Uburyo bwo gushiraho buterwa na geometrie ipfa, umuvuduko wurupfu, ubushyuhe bwo gupfa, hamwe na rheologiya. Igikorwa cyo gushiraho kigomba guhindurwa kugirango kigere kumurongo umwe kandi woroshye udafite inenge, nko gupfa kubyimba, kuvunika gushonga, cyangwa guhungabana kurwego. Nyuma yuburyo bwo gushiraho, extrudates irakonjeshwa, igacibwa, kandi igakusanywa nibikoresho byo hepfo, nka kalibatori, gutwara, gukata, hamwe na winders.
Umwanzuro
Conin twin screw extruder nigikoresho kinini kandi cyiza cyo gukora ibicuruzwa bya PVC na WPC biva mu ifu ivanze. Irashobora gutanga imirimo ikenewe yo kugaburira, gushonga, devolatilisation, no gushiraho muburyo bukomeza kandi bugenzurwa. Irashobora kandi kubyara ibicuruzwa bitandukanye bifite imiterere, ingano, nimirimo itandukanye, ukoresheje ibikoresho bitandukanye kandi byimbere. Impuzamugambi ya conin ifite ibyiza byo guteranya neza, umusaruro munini, gukora neza, hamwe nubuzima burebure, kandi birashobora guhaza ibyifuzo bitandukanye byabakiriya nisoko.
