polivinil hlorid (PVC) je jedan od najčešće korištenih sintetičkih polimera u svijetu, cijenjen zbog svoje izvrsne svestranosti, isplativost, hemijska otpornost, i mehanička svojstva. Prodrla je u skoro sve oblasti modernog života, od konstrukcije i pakovanja do automobilizma, električne i elektronske industrije. Međutim, čista PVC smola ima inherentna ograničenja kao što je loša termička stabilnost, nedovoljna otpornost na udar, i uzak prozor za obradu, koji ograničavaju njegovu primjenu u scenarijima visokih performansi. Za prevazilaženje ovih nedostataka i proširenje opsega njegove primjene, Tehnologija miješanja PVC smjese pojavila se kao ključna karika u industriji prerade PVC-a. Ova tehnologija uključuje miješanje PVC smole s raznim aditivima (kao što su plastifikatori, stabilizatori, punila, maziva, i modifikatori) kroz profesionalnu opremu, nakon čega slijedi granulacija ili direktno oblikovanje, za dobivanje PVC smjese sa prilagođenim svojstvima koja ispunjavaju specifične zahtjeve primjene.
Akumulirali smo duboko i jedinstveno iskustvo u oblasti mešanja i obrade PVC smesa. Tokom godina, posvećeni smo istraživanju i optimizaciji tehnologije obrade PVC-a, i razvili ciljana rješenja za ekstruziju za različite vrste PVC materijala (uključujući čvrsti PVC, fleksibilni PVC, i modifikovani PVC). Naš tehnički tim ima duboko razumijevanje karakteristika obrade raznih PVC smola i aditiva, i može pružiti prilagođena rješenja prema specifičnim potrebama kupaca. Bilo da se radi o standardnom PVC proizvodu ili specijalnoj modificiranoj PVC smjesi sa strogim zahtjevima za performanse, možemo osigurati stabilan i pouzdan kvalitet obrade kroz naučni dizajn procesa i naprednu konfiguraciju opreme.
1. Pregled tehnologije miješanja PVC smjesa
1.1 Osnovni principi miješanja PVC smjesa
Miješanje PVC smjese je složen fizički i kemijski proces koji integrira čvrsto miješanje, topljenje, plastificiranje, šišanje, i homogenizacija. Osnovni cilj je ravnomjerno dispergirati različite aditive u matricu PVC smole, otkloniti unutrašnje nedostatke (kao što su mehurići vazduha, aglomeracija, i neravnomjerna raspodjela komponenti) mješavine, i poboljšati stepen plastifikacije i performanse obrade jedinjenja, kako bi se postavila čvrsta osnova za naknadnu obradu kalupa (kao što je ekstruzija, brizganje, kalandriranje) i performanse finalnog proizvoda.
Proces miješanja PVC smjesa obično se dijeli u dvije faze: suvo mešanje i mešanje taline. Suvo miješanje je početna faza, što uglavnom uključuje miješanje praha PVC smole sa raznim aditivima (kao što su stabilizatori, maziva, punila, plastifikatori za fleksibilni PVC) u mikseru velike brzine. Svrha suhog miješanja je da se aditivi ravnomjerno prianjaju na površinu čestica PVC smole djelovanjem mehaničkog miješanja i topline trenja., i zagrijati smjesu na određenu temperaturu, što pogoduje naknadnoj plastifikaciji taline. Mešanje taline je ključna faza, koji se obično dovršava u ekstruderima ili internim mikserima. Pod kombiniranim djelovanjem vanjskog grijanja i posmične sile koju stvara vijak (ili rotor), čestice PVC smole se postepeno tope i plastificiraju, a aditivi se dalje raspršuju u matricu smole na molekularnom nivou kako bi se formirao ujednačen i stabilan sistem taline. Konačno, talina je ekstrudirana, granulirani ili direktno oblikovani u proizvode.
1.2 Ključni aditivi za miješanje PVC smjesa
Performanse PVC smjesa u velikoj mjeri su određene vrstom, doziranje i efekat mešanja aditiva. Različiti aditivi igraju različite uloge u procesu miješanja i prerade i finalnih proizvoda. Sljedeći su ključni aditivi koji se obično koriste u miješanju PVC smjese:
1.2.1 Stabilizatori:
PVC smola je sklona termičkoj degradaciji na visokim temperaturama (iznad 100℃), što će dovesti do promjene boje (od bijele do žute, braon, cak i crna), smanjenje mehaničkih svojstava i gubitak upotrebne vrijednosti. Stoga, PVC smjesama se moraju dodati stabilizatori kako bi se poboljšala njihova termička stabilnost. Uobičajeni PVC stabilizatori uključuju stabilizatore na bazi olova, kalcijum-cink kompozitni stabilizatori, barijum-kadmijum stabilizatori, i organski stabilizatori kalaja. Među njima, Kalcij-cink kompozitni stabilizatori se široko koriste zbog svoje ekološke prihvatljivosti, netoksičnost, i dobra termička stabilnost, koji su u skladu sa globalnim zahtjevima zaštite okoliša za plastične proizvode.
1.2.2 Plastifikatori:
Plastifikatori se uglavnom koriste u fleksibilnim PVC smjesama za smanjenje temperature staklastog prijelaza PVC smole, poboljšati njegovu fleksibilnost, žilavost i obradivost. Mogu prodrijeti u molekularni lanac PVC-a, oslabi intermolekularnu silu, čine molekularni lanac lakim za kretanje, čime PVC masa postaje mekana i laka za obradu. Uobičajeni plastifikatori uključuju dioktil ftalat (DOP), dioktil tereftalat (DOTP), diizononil ftalat (DINP), i epoksidno sojino ulje. Među njima, DOTP ima prednosti zaštite životne sredine, niska volatilnost, i dobra kompatibilnost sa PVC-om, i široko se koristi u visokokvalitetnim fleksibilnim PVC proizvodima (kao što su medicinska creva, folije za pakovanje hrane).
1.2.3 Punila:
Punila se dodaju PVC smjesama kako bi se smanjili troškovi proizvodnje, poboljšati krutost, tvrdoća, otpornost na habanje i stabilnost dimenzija proizvoda, i podesiti gustinu jedinjenja. Uobičajeni punioci uključuju kalcijum karbonat (lagani kalcijum karbonat, teški kalcijum karbonat), talk puder, kaolin, i čađe. Kalcijum karbonat je najrasprostranjenije punilo zbog svoje niske cene, obilni izvori, i dobra kompatibilnost sa PVC-om. Dodavanje odgovarajuće količine kalcijum karbonata ne samo da može smanjiti troškove već i poboljšati fluidnost obrade i otpornost na udarce PVC smjese.
1.2.4 Maziva:
Lubrikanti se koriste za smanjenje trenja između čestica PVC smole, između mješavine i opreme (kao što je unutrašnji zid miksera, vijak ekstrudera), i između taline i kalupa, kako bi se poboljšala fluidnost obrade smjese, spriječiti prianjanje materijala na opremu, i osigurati nesmetan napredak procesa miješanja i oblikovanja. Uobičajena maziva uključuju stearinsku kiselinu, kalcijum stearat, cink stearat, i parafin. Prema mehanizmu djelovanja, maziva se mogu podijeliti na unutarnja maziva i vanjska maziva. Unutrašnja maziva mogu smanjiti trenje između PVC molekularnih lanaca, poboljšati efikasnost plastifikacije; vanjska maziva mogu formirati film za podmazivanje na površini materijala, smanjiti trenje između materijala i opreme.
1.2.5 Modifikatori:
Modifikatori se dodaju za poboljšanje specifičnih svojstava PVC smjesa, kao što je otpornost na udarce, otpornost na toplotu, i transparentnost. Uobičajeni modifikatori uključuju akrilonitril-butadien-stiren (ABS) smola, metil metakrilat-butadien-stiren (MBS) smola, klorirani polietilen (CPE), i akrilne smole. Na primjer, MBS smola može značajno poboljšati otpornost na udare krutih PVC smjesa, što ih čini pogodnim za proizvodnju plastičnih cijevi, profili, i dijelovi za brizganje koji zahtijevaju visoku žilavost.
1.3 Važnost modifikacije i granulacije PVC spoja
U većini scenarija obrade PVC-a, PVC smolu je potrebno prvo modificirati i granulirati prije naknadne obrade kalupa. To je zato što modificirana granulacija može donijeti mnoge očigledne prednosti:
Prvo, poboljšava stepen plastificiranja PVC-a. Kombinovanim djelovanjem suhog miješanja i miješanja taline u procesu granulacije, Čestice PVC smole su potpuno otopljene i plastificirane, a aditivi su jednolično dispergovani, čime se izbjegavaju problemi nedovoljne plastifikacije, neravnomjerna raspodjela komponenti, i unutrašnji nedostaci u direktnom oblikovanju čiste smole, čime se poboljšavaju performanse obrade materijala.
Drugo, pojednostavljuje naknadni proces obrade. PVC granule nakon modifikacije i granulacije imaju ujednačenu veličinu čestica, dobra fluidnost, i stabilne performanse. Mogu se direktno koristiti u ekstruziji, brizganje, kalandriranje, puhanje i drugi procesi oblikovanja bez dodatnog miješanja ili predobrade, što smanjuje proces proizvodnje, poboljšava efikasnost proizvodnje, i smanjuje radni intenzitet operatera.
Treće, osigurava stabilnost kvaliteta proizvoda. Performanse modificiranih PVC granula su relativno stabilne, koji može izbjeći fluktuaciju performansi proizvoda uzrokovanu neravnomjernim miješanjem aditiva u direktnom oblikovanju, čime se osigurava konzistentnost kvaliteta proizvoda i smanjuje stopa kvarova na proizvodu.
Četvrto, proširuje opseg primjene PVC-a. Kroz ciljanu modifikaciju (kao što je dodavanje različitih modifikatora, plastifikatori, i punila), Mogu se pripremiti PVC smjese različitih svojstava, koji mogu zadovoljiti zahtjeve različitih područja primjene. Na primjer, krute PVC granule visoke krutosti i otpornosti na udar mogu se koristiti u proizvodnji plastičnih cijevi i profila; fleksibilne PVC granule dobre fleksibilnosti i mekoće mogu se koristiti u proizvodnji crijeva, kablovi, i folije za pakovanje; PVC granule otporne na plamen mogu se koristiti u proizvodnji električnih i elektronskih proizvoda.
Treba naglasiti da za PVC proizvode sa posebnim zahtjevima (kao što je otpornost na visoke temperature, otpornost na koroziju, otpornost na plamen, i transparentnost) i PVC modifikovane formule, uvijek vršimo prilagođeni razvoj prema specifičnim potrebama kupaca. Naš tehnički tim će voditi detaljnu komunikaciju s kupcima kako bi razumjeli scenarije upotrebe njihovih proizvoda, zahtjevi performansi, i troškovi proizvodnje, a zatim dizajnirati najprikladniju modificiranu formulu i proces miješanja kako bi se osiguralo da proizvedeni PVC spojevi mogu u potpunosti ispuniti očekivanja kupaca.
2. Ekstruzijska oprema za miješanje i granulaciju PVC smjese

U pogledu konstrukcijskog dizajna, ekstruder serije HTE ima strukturu sa dva vijka, which has obvious advantages compared with the single-screw extruder in terms of shear mixing, plasticization efficiency, i proizvodni kapacitet. The twin-screw can generate strong shear force and mixing effect during rotation, which can make the PVC mixture and additives more uniformly mixed, and the plasticization degree is higher, thus improving the performance of the PVC compound. According to the shape of the screw, the twin-screw extruder can be divided into conical twin-screw extruder and parallel twin-screw extruder. Među njima, the conical twin-screw extruder is an ideal choice for rigid PVC compound mixing and granulation.
The conical twin-screw extruder in the HTE series has a unique conical screw design, with a large screw diameter at the feeding end and a small screw diameter at the extrusion end. Ovaj dizajn može učiniti da se PVC mješavina postepeno komprimira u procesu transporta, a sila smicanja se postepeno povećava, što pogoduje topljenju i plastifikaciji krute PVC smole (koji ima visoku viskoznost i zahtijeva jaku silu smicanja za plastifikaciju). U isto vreme, konusni ekstruder s dva puža ima dobre performanse samočišćenja, što može izbjeći nakupljanje materijala u vijku i cijevi, smanjiti rasipanje materijala, i osigurati stabilnost proizvodnog procesa.
U smislu odabira materijala, vijak i cijev ekstrudera HTE serije izrađeni su od visokokvalitetnog legiranog čelika otpornog na habanje i koroziju,Nakon posebne površinske obrade (kao što je tretman nitriranjem), što dodatno poboljšava tvrdoću i otpornost na habanje vijka i cijevi, and can adapt to the mixing and granulation of PVC compounds containing fillers (such as calcium carbonate) and corrosive additives, prolonging the service life of the equipment.
In terms of performance advantages, the HTE series extruder has the characteristics of high production capacity, niska potrošnja energije, and good product quality.

If the production demand is small (less than 100kg/h), the ZTE MODEL extruder is suitable; if the production demand is large (more than 100kg/h), the HTE series extruder is more suitable.
2.3.3 Product Quality Requirements:
Ako proizvodi kupca imaju stroge zahtjeve u pogledu performansi (kao što je otpornost na udarce, transparentnost, otpornost na plamen), treba izabrati ekstruder serije HTE sa visokom efikasnošću plastifikacije i ujednačenim efektom mešanja; ako su zahtjevi za kvalitetom proizvoda opći, može se odabrati ekstruder ZTE MODEL sa stabilnim performansama i visokim troškovima.
2.3.4 Potrošnja energije i troškovi održavanja:
Potrošnja energije i troškovi održavanja važni su faktori koji utiču na dugoročne proizvodne troškove kupaca. Ekstruder serije HTE ima prednost niske potrošnje energije po jedinici proizvoda, ali početna investicija je relativno visoka; ZTE MODEL ekstruder ima niže početne investicije i troškove održavanja, koji je pogodan za kupce sa ograničenim budžetom.
2.3.5 Kompatibilnost sa pomoćnom opremom:
The selected extruder should be compatible with the existing auxiliary equipment (such as mixers, peletizatori, and conveyors) to form a complete production line, avoiding the problem of equipment mismatch affecting production efficiency.
Our professional technical team can provide one-stop consulting and selection services for customers. According to the customer’s specific needs, we will recommend the most suitable extruder model and provide customized equipment configuration and process design to help customers achieve the best production effect with the most reasonable cost.
