Polivinil klorid (PVC) jedan je od najraširenijih sintetičkih polimera na svijetu, cijenjen zbog svoje izvrsne svestranosti, isplativost, kemijska otpornost, i mehanička svojstva. Prodro je u gotovo sva područja modernog života, od gradnje i pakiranja do automobilske industrije, elektro i elektroničke industrije. Međutim, čista PVC smola ima svojstvena ograničenja kao što je slaba toplinska stabilnost, nedovoljna otpornost na udarce, i uzak prozor obrade, koji ograničavaju njegovu primjenu u scenarijima visokih performansi. Da bi se prevladali ti nedostaci i proširio opseg njegove primjene, Tehnologija miješanja PVC smjesa pojavila se kao ključna karika u industriji prerade PVC-a. Ova tehnologija uključuje miješanje PVC smole s različitim dodacima (kao što su plastifikatori, stabilizatori, punila, maziva, i modifikatore) putem profesionalne opreme, nakon čega slijedi granulacija ili izravno kalupljenje, za dobivanje PVC smjesa s prilagođenim svojstvima koja zadovoljavaju specifične zahtjeve primjene.
Stekli smo duboko i jedinstveno iskustvo u području miješanja i obrade PVC smjesa. Tijekom godina, predani smo istraživanju i optimizaciji tehnologija obrade PVC-a, i razvili ciljana rješenja ekstruzije za različite vrste PVC materijala (uključujući kruti PVC, fleksibilni PVC, i modificirani 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 posebnoj modificiranoj PVC smjesi sa strogim zahtjevima za performanse, možemo osigurati stabilnu i pouzdanu kvalitetu obrade kroz znanstveni dizajn procesa i konfiguraciju napredne opreme.
1. Pregled tehnologije miješanja PVC smjesa
1.1 Osnovni principi miješanja PVC smjesa
Miješanje PVC spojeva složen je fizikalni i kemijski proces koji uključuje miješanje krutih tvari, topljenje, plastificiranje, šišanje, i homogenizacija. Osnovni cilj je ravnomjerno raspršiti različite aditive u matricu PVC smole, otkloniti unutarnje nedostatke (kao što su mjehurići zraka, aglomeracija, i neravnomjerna raspodjela komponenti) smjese, i poboljšati stupanj plastifikacije i učinak obrade spoja, kako bi se postavio čvrst temelj za kasniju obradu kalupljenjem (kao što je ekstruzija, injekcijsko prešanje, kalandriranje) i učinak konačnog proizvoda.
Proces miješanja PVC smjesa obično se dijeli u dvije faze: suho miješanje i miješanje taline. Dry mixing is the initial stage, which mainly involves mixing PVC resin powder with various additives (such as stabilizers, maziva, punila, plasticizers for flexible PVC) in a high-speed mixer. The purpose of dry mixing is to make the additives uniformly adhere to the surface of PVC resin particles through the action of mechanical stirring and friction heat, and to preheat the mixture to a certain temperature, which is conducive to the subsequent melt plasticization. Melt mixing is the key stage, which is usually completed in extruders or internal mixers. Under the combined action of external heating and shear force generated by the screw (or rotor), the PVC resin particles are gradually melted and plasticized, and the additives are further dispersed into the resin matrix at the molecular level to form a uniform and stable melt system. Konačno, the melt is extruded, granulated or directly formed into products.
1.2 Key Additives for PVC Compound Mixing
The performance of PVC compounds is largely determined by the type, dosage and mixing effect of additives. Different additives play different roles in the mixing and processing process and the final products. The following are the key additives commonly used in PVC compound mixing:
1.2.1 Stabilizers:
PVC resin is prone to thermal degradation at high temperatures (above 100℃), which will lead to discoloration (from white to yellow, brown, even black), reduction of mechanical properties and loss of use value. Stoga, stabilizers must be added to PVC compounds to improve their thermal stability. Common PVC stabilizers include lead-based stabilizers, calcium-zinc composite stabilizers, barium-cadmium stabilizers, and organic tin stabilizers. Među njima, calcium-zinc composite stabilizers are widely used due to their environmental friendliness, non-toxicity, and good thermal stability, which are in line with the global environmental protection requirements for plastic products.
1.2.2 Plasticizers:
Plasticizers are mainly used in flexible PVC compounds to reduce the glass transition temperature of PVC resin, improve its flexibility, toughness and processability. They can penetrate into the molecular chain of PVC, weaken the intermolecular force, make the molecular chain easy to move, thus making the PVC compound soft and easy to process. Common plasticizers include dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), and epoxy soybean oil. Među njima, DOTP ima prednosti zaštite okoliša, niska volatilnost, i dobru kompatibilnost s PVC-om, i naširoko se koristi u visokokvalitetnim fleksibilnim PVC proizvodima (kao što su medicinska crijeva, folije za pakiranje hrane).
1.2.3 Punila:
PVC smjesama se dodaju punila kako bi se smanjili troškovi proizvodnje, poboljšati krutost, tvrdoća, otpornost na habanje i dimenzionalna stabilnost proizvoda, i prilagoditi gustoću spojeva. Uobičajena punila uključuju kalcijev karbonat (lagani kalcijev karbonat, teški kalcijev karbonat), puder od talka, kaolin, i čađa. Kalcijev karbonat je najviše korišteno punilo zbog niske cijene, izdašni izvori, i dobru kompatibilnost s PVC-om. Dodavanje odgovarajuće količine kalcijevog karbonata ne samo da može smanjiti troškove, već i poboljšati fluidnost obrade i otpornost PVC spojeva na udarce.
1.2.4 Maziva:
Maziva se koriste za smanjenje trenja između čestica PVC smole, između smjese i opreme (kao što je unutarnja stijenka miješalice, puž ekstrudera), a između taline i kalupa, tako da se poboljša fluidnost obrade spoja, spriječiti prianjanje materijala na opremu, i osigurati glatko napredovanje procesa miješanja i oblikovanja. Uobičajeni lubrikanti uključuju stearinsku kiselinu, kalcijev stearat, cinkov stearat, i parafin. Prema mehanizmu djelovanja, maziva se mogu podijeliti na unutarnja maziva i vanjska maziva. Unutarnja maziva mogu smanjiti trenje između PVC molekularnih lanaca, poboljšati učinkovitost plastifikacije; vanjska maziva mogu stvoriti mazivi film na površini materijala, smanjiti trenje između materijala i opreme.
1.2.5 Modifikatori:
Dodani su modifikatori za poboljšanje specifičnih svojstava PVC spojeva, kao što je otpornost na udarce, otpornost na toplinu, 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 krutih PVC spojeva na udarce, čineći ih prikladnima za proizvodnju plastičnih cijevi, profilima, i dijelovi za injekcijsko prešanje koji zahtijevaju visoku žilavost.
1.3 Važnost modifikacije i granulacije PVC spojeva
U većini scenarija obrade PVC-a, PVC smolu treba prvo modificirati i granulirati prije naknadne obrade kalupljenjem. To je zato što modificirana granulacija može donijeti mnoge očite prednosti:
Prvi, poboljšava stupanj plastificiranja PVC-a. Kroz kombinirano djelovanje suhog miješanja i miješanja taline u procesu granulacije, Čestice PVC smole su potpuno otopljene i plastificirane, a dodaci su ravnomjerno raspršeni, čime se izbjegavaju problemi nedovoljne plastifikacije, neravnomjerna raspodjela komponenti, i unutarnji nedostaci u izravnom kalupljenju čiste smole, čime se poboljšavaju performanse obrade materijala.
Drugi, to pojednostavljuje kasniji proces obrade. PVC granule nakon modifikacije i granulacije imaju ujednačenu veličinu čestica, dobra fluidnost, i stabilne performanse. Mogu se izravno koristiti u ekstruziji, injekcijsko prešanje, kalandriranje, puhanje i drugi postupci kalupljenja bez dodatnog miješanja ili predobrade, što smanjuje proizvodni proces, poboljšava učinkovitost proizvodnje, te smanjuje intenzitet rada operatera.
Treći, osigurava stabilnost kvalitete proizvoda. Učinak modificiranih PVC granula je relativno stabilan, čime se može izbjeći fluktuacija performansi proizvoda uzrokovana neravnomjernim miješanjem aditiva u izravnom kalupljenju, čime se osigurava dosljednost kvalitete proizvoda i smanjuje stopa nedostataka proizvoda.
Četvrti, proširuje područje primjene PVC-a. Putem ciljane izmjene (kao što je dodavanje različitih modifikatora, plastifikatori, i punila), Mogu se pripremiti PVC spojevi s različitim svojstvima, koji može zadovoljiti zahtjeve različitih područja primjene. Na primjer, krute PVC granule visoke krutosti i otpornosti na udarce mogu se koristiti u proizvodnji plastičnih cijevi i profila; savitljive PVC granule dobre fleksibilnosti i mekoće mogu se koristiti u proizvodnji crijeva, kabeli, i folije za pakiranje; PVC granule otporne na plamen mogu se koristiti u proizvodnji električnih i elektroničkih proizvoda.
Treba naglasiti da za PVC proizvode s posebnim zahtjevima (kao što je otpornost na visoke temperature, otpornost na koroziju, otpornost na plamen, i transparentnost) i PVC modificirane formule, we always carry out customized development according to the specific needs of customers. Our technical team will conduct in-depth communication with customers to understand their product usage scenarios, performance requirements, and production costs, and then design the most suitable modified formula and mixing process to ensure that the produced PVC compounds can fully meet the customer’s expectations.
2. Extrusion Equipment for PVC Compound Mixing and Granulation
Extruders are the core equipment for PVC compound mixing, granulation, and molding processing. They play a crucial role in the melt plasticization, shear mixing, and extrusion molding of PVC mixtures. The working principle of extruders is to use external power transmission to drive the screw to rotate, i koristiti prijenos topline vanjskih grijaćih elemenata i posmične topline generirane rotacijom vijka kako bi se ostvario prijenos čvrste tvari, zbijanje, topljenje, shear mixing, i ekstruzija PVC materijala. Kao važna oprema u preradi plastike, Ekstruderi se široko koriste u granulaciji PVC spojeva i prešanju raznih PVC proizvoda, te zauzimaju nezamjenjivo mjesto u industriji prerade PVC-a.
