Polyvinyylikloridi (PVC) on yksi maailman laajimmin käytetyistä synteettisistä polymeereistä, arvostettu erinomaisesta monipuolisuudestaan, kustannustehokkuutta, kemiallinen kestävyys, ja mekaaniset ominaisuudet. Se on tunkeutunut lähes kaikille nykyajan elämän aloille, rakentamisesta ja pakkaamisesta autoteollisuuteen, sähkö- ja elektroniikkateollisuudessa. Kuitenkin, puhtaalla PVC-hartsilla on luontaisia rajoituksia, kuten huono lämmönkestävyys, riittämätön iskunkestävyys, ja kapea käsittelyikkuna, jotka rajoittavat sen käyttöä korkean suorituskyvyn skenaarioissa. Voit voittaa nämä puutteet ja laajentaa sen sovellusaluetta, PVC-seosten sekoitustekniikka on noussut PVC-jalostusteollisuuden avainlinkiksi. Tämä tekniikka sisältää PVC-hartsin sekoittamisen erilaisiin lisäaineisiin (kuten pehmittimet, stabilointiaineet, täyteaineet, voiteluaineet, ja modifioijia) ammattilaitteiden kautta, jota seuraa rakeistus tai suora muovaus, saada PVC-yhdisteitä, joilla on räätälöidyt ominaisuudet ja jotka täyttävät erityiset käyttövaatimukset.
Meillä on syvällinen ja ainutlaatuinen kokemus PVC-yhdisteiden sekoituksen ja käsittelyn alalla. Vuosien varrella, olemme sitoutuneet tutkimaan ja optimoimaan PVC-käsittelytekniikoita, ja ovat kehittäneet kohdennettuja ekstruusioratkaisuja erityyppisille PVC-materiaaleille (mukaan lukien jäykkä PVC, joustava PVC, ja modifioitu PVC). Teknisellä tiimillämme on syvä ymmärrys erilaisten PVC-hartsien ja lisäaineiden käsittelyominaisuuksista, ja voi tarjota räätälöityjä ratkaisuja asiakkaiden erityistarpeiden mukaan. Olipa kyseessä tavallinen PVC-tuote tai erityinen muunneltu PVC-seos, jolla on tiukat suorituskykyvaatimukset, voimme varmistaa vakaan ja luotettavan käsittelyn laadun tieteellisen prosessisuunnittelun ja edistyneiden laitteiden konfiguroinnin avulla.
1. Yleiskatsaus PVC:n sekoitustekniikasta
1.1 PVC-yhdisteiden sekoittamisen perusperiaatteet
PVC-seoksen sekoitus on monimutkainen fysikaalinen ja kemiallinen prosessi, joka yhdistää kiinteän aineen sekoittamisen, sulaminen, plastisoimalla, leikkaus, ja homogenointi. Ydintavoitteena on erilaisten lisäaineiden tasainen dispergointi PVC-hartsimatriisiin, poistaa sisäiset viat (kuten ilmakuplia, taajama, ja komponenttien epätasainen jakautuminen) seoksesta, ja parantaa yhdisteen pehmitysastetta ja prosessointikykyä, jotta voidaan luoda vankka perusta myöhemmälle muovauskäsittelylle (kuten ekstruusio, ruiskuvalu, kalanterointi) ja lopputuotteen suorituskyky.
PVC-yhdisteiden sekoitusprosessi on yleensä jaettu kahteen vaiheeseen: kuivasekoitus ja sulasekoitus. Kuivasekoitus on alkuvaihe, jossa pääasiassa sekoitetaan PVC-hartsijauhetta erilaisiin lisäaineisiin (kuten stabilointiaineet, voiteluaineet, täyteaineet, pehmittimet joustavalle PVC:lle) nopeassa mikserissä. Kuivasekoituksen tarkoituksena on saada lisäaineet kiinnittymään tasaisesti PVC-hartsihiukkasten pintaan mekaanisen sekoituksen ja kitkalämmön vaikutuksesta., ja esilämmittää seos tiettyyn lämpötilaan, mikä edistää myöhempää sulapehmittimistä. Sulasekoitus on avainvaihe, joka yleensä valmistetaan ekstruudereissa tai sisäisissä sekoittimissa. Ulkoisen kuumennuksen ja ruuvin tuottaman leikkausvoiman yhteisvaikutuksena (tai roottori), PVC-hartsihiukkaset sulavat ja pehmenevät vähitellen, ja lisäaineet dispergoidaan edelleen hartsimatriisiin molekyylitasolla yhtenäisen ja vakaan sulatusjärjestelmän muodostamiseksi. Lopulta, sula suulakepuristetaan, rakeistettu tai suoraan tuotteiksi muodostettu.
1.2 Tärkeimmät lisäaineet PVC-seosten sekoittamiseen
The performance of PVC compounds is largely determined by the type, lisäaineiden annostus ja sekoitusvaikutus. 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 Stabilisaattorit:
PVC resin is prone to thermal degradation at high temperatures (yli 100 ℃), mikä johtaa värjäytymiseen (valkoisesta keltaiseen, ruskea, jopa musta), reduction of mechanical properties and loss of use value. Siksi, stabilizers must be added to PVC compounds to improve their thermal stability. Common PVC stabilizers include lead-based stabilizers, kalsium-sinkki-komposiittistabilisaattorit, barium-kadmium-stabilisaattorit, ja orgaaniset tinastabilisaattorit. Heidän joukossaan, calcium-zinc composite stabilizers are widely used due to their environmental friendliness, myrkyttömyys, ja hyvä lämmönkestävyys, jotka ovat muovituotteiden maailmanlaajuisten ympäristönsuojeluvaatimusten mukaisia.
1.2.2 Pehmittimet:
Pehmittimiä käytetään pääasiassa joustavissa PVC-yhdisteissä PVC-hartsin lasittumislämpötilan alentamiseksi, parantaa sen joustavuutta, sitkeys ja prosessoitavuus. Ne voivat tunkeutua PVC:n molekyyliketjuun, heikentää molekyylien välistä voimaa, tehdä molekyyliketjusta helppo liikuttaa, jolloin PVC-seoksesta tulee pehmeä ja helppo käsitellä. Yleisiä pehmittimiä ovat dioktyyliftalaatti (DOP), dioktyylitereftalaatti (DOTP), diisononyyliftalaatti (DINP), ja epoksi soijaöljyä. Heidän joukossaan, DOTP:llä on ympäristönsuojelun edut, alhainen volatiliteetti, ja hyvä yhteensopivuus PVC:n kanssa, ja sitä käytetään laajalti korkealaatuisissa joustavissa PVC-tuotteissa (kuten lääketieteelliset letkut, elintarvikkeiden pakkauskalvot).
1.2.3 Täyteaineet:
PVC-seoksiin lisätään täyteaineita tuotantokustannusten alentamiseksi, parantaa jäykkyyttä, kovuus, kulutuskestävyys ja tuotteiden mittapysyvyys, ja säädä yhdisteiden tiheyttä. Yleisiä täyteaineita ovat kalsiumkarbonaatti (kevyt kalsiumkarbonaatti, raskas kalsiumkarbonaatti), talkki, kaoliini, ja hiilimustaa. Kalsiumkarbonaatti on yleisimmin käytetty täyteaine edullisen hinnan vuoksi, runsaat lähteet, ja hyvä yhteensopivuus PVC:n kanssa. Sopivan määrän kalsiumkarbonaattia lisääminen ei voi vain vähentää kustannuksia, vaan myös parantaa PVC-yhdisteiden käsittelyn sujuvuutta ja iskunkestävyyttä.
1.2.4 Voiteluaineet:
Voiteluaineita käytetään vähentämään PVC-hartsihiukkasten välistä kitkaa, seoksen ja laitteiston välillä (kuten sekoittimen sisäseinämä, suulakepuristimen ruuvi), ja sulatteen ja muotin välissä, yhdisteen käsittelyn juoksevuuden parantamiseksi, estää materiaalia tarttumasta laitteeseen, ja varmistavat sekoitus- ja muovausprosessin sujuvan etenemisen. Yleisiä voiteluaineita ovat steariinihappo, kalsiumstearaatti, sinkkistearaatti, ja parafiini. Toimintamekanismin mukaan, voiteluaineet voidaan jakaa sisäisiin voiteluaineisiin ja ulkoisiin voiteluaineisiin. Sisäiset voiteluaineet voivat vähentää PVC-molekyyliketjujen välistä kitkaa, parantaa plastisoinnin tehokkuutta; ulkoiset voiteluaineet voivat muodostaa voitelukalvon materiaalin pintaan, vähentää materiaalin ja laitteen välistä kitkaa.
1.2.5 Muokkaimet:
Muokkausaineita lisätään parantamaan PVC-yhdisteiden erityisominaisuuksia, kuten iskunkestävyys, lämmönkestävyys, ja läpinäkyvyys. Yleisiä muuntoaineita ovat akryylinitriili-butadieeni-styreeni (ABS) hartsi, metyylimetakrylaatti-butadieeni-styreeni (MBS) hartsi, kloorattu polyeteeni (CPE), ja akryylihartsia. Esimerkiksi, MBS-hartsi voi merkittävästi parantaa jäykkien PVC-yhdisteiden iskunkestävyyttä, making them suitable for the production of plastic pipes, profiilit, ja ruiskuvaluosat, jotka vaativat suurta sitkeyttä.
1.3 PVC-yhdisteiden modifioinnin ja granuloinnin merkitys
Useimmissa PVC-käsittelyskenaarioissa, PVC resin needs to be modified and granulated first before subsequent molding processing. This is because modified granulation can bring many obvious advantages:
Ensimmäinen, se parantaa PVC:n pehmitysastetta. Through the combined action of dry mixing and melt mixing in the granulation process, PVC resin particles are fully melted and plasticized, ja lisäaineet jakautuvat tasaisesti, which avoids the problems of insufficient plasticization, komponenttien epätasainen jakautuminen, and internal defects in direct molding of pure resin, thus improving the processing performance of the material.
Toinen, se yksinkertaistaa myöhempää käsittelyprosessia. The PVC granules after modification and granulation have uniform particle size, hyvä juoksevuus, ja vakaa suorituskyky. Niitä voidaan käyttää suoraan suulakepuristuksessa, ruiskuvalu, kalanterointi, blow molding and other molding processes without additional mixing or preprocessing, mikä vähentää tuotantoprosessia, parantaa tuotannon tehokkuutta, ja vähentää toimijoiden työvoimaintensiteettiä.
Kolmas, se varmistaa tuotteen laadun vakauden. The performance of modified PVC granules is relatively stable, which can avoid the fluctuation of product performance caused by uneven mixing of additives in direct molding, thus ensuring the consistency of product quality and reducing the product defect rate.
Neljäs, se laajentaa PVC:n käyttöaluetta. Kohdennettujen muutosten kautta (kuten lisäämällä erilaisia modifikaatioita, pehmittimet, ja täyteaineet), PVC compounds with different properties can be prepared, which can meet the requirements of different application fields. Esimerkiksi, rigid PVC granules with high rigidity and impact resistance can be used in the production of plastic pipes and profiles; flexible PVC granules with good flexibility and softness can be used in the production of hoses, kaapelit, and packaging films; flame-retardant PVC granules can be used in the production of electrical and electronic products.
It should be emphasized that for PVC products with special requirements (kuten korkeiden lämpötilojen kestävyys, korroosionkestävyys, palonesto, ja läpinäkyvyys) ja PVC-muokatut kaavat, 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, ja suunnittele sitten sopivin muunneltu kaava ja sekoitusprosessi varmistaaksesi, että valmistetut PVC-yhdisteet täyttävät täysin asiakkaan odotukset.
2. Extrusion Equipment for PVC Compound Mixing and Granulation
Extruders are the core equipment for PVC compound mixing, rakeistus, and molding processing. They play a crucial role in the melt plasticization, shear mixing, ja PVC-seosten ekstruusiomuovaus. The working principle of extruders is to use external power transmission to drive the screw to rotate, and use the heat transfer of external heating elements and the shear heat generated by the rotation of the screw to realize the solid conveying, compaction, sulaminen, shear mixing, and extrusion of PVC materials. As an important equipment in plastic molding processing, extruders are widely used in the granulation of PVC compounds and the molding of various PVC products, and occupy an irreplaceable position in the PVC processing industry.
According to the structure and performance of extruders, we have developed two series of extruders suitable for PVC compound mixing and granulation, namely the ZTE MODEL series and the HTE series. These two series of extruders have their own characteristics and advantages, and can meet the different needs of customers for production capacity, tuotteen laatu, and cost control.

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. This design can make the PVC mixture gradually compressed in the process of conveying, and the shear force gradually increases, which is conducive to the melting and plasticization of rigid PVC resin (which has high viscosity and requires strong shear force for plasticization). Samaan aikaan, the conical twin-screw extruder has good self-cleaning performance, which can avoid the accumulation of material in the screw and barrel, reduce the waste of material, and ensure the stability of the production process.
In terms of material selection, the screw and barrel of the HTE series extruder are made of high-quality wear-resistant and corrosion-resistant alloy steel,经过 special surface treatment (such as nitriding treatment), which further improves the hardness and wear resistance of the screw and barrel, and can adapt to the mixing and granulation of PVC compounds containing fillers (kuten kalsiumkarbonaatti) 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, low energy consumption, and good product quality. Compared with the ZTE MODEL extruder, the HTE series extruder can increase the production capacity by 30%-50% under the same power condition, and the energy consumption per unit product can be reduced by 20%-30%, which can effectively reduce the production cost of customers and improve the market competitiveness of their products. Samaan aikaan, the HTE series extruder has a more precise temperature control system and speed control system, which can accurately control the plasticization temperature, shear speed, and extrusion pressure of the PVC mixture, ensuring that the performance of the produced PVC granules is stable and uniform, and meeting the strict requirements of high-end products.
Lisäksi, the HTE series extruder is equipped with an advanced intelligent control system, which adopts a touch screen control panel and can realize real-time monitoring and adjustment of the production process. The control system has functions such as fault alarm, parameter memory, and automatic shutdown, which can effectively improve the safety and reliability of the production process, reduce the labor intensity of operators, and improve production efficiency. The HTE series extruder can also be matched with high-end auxiliary equipment (such as precision high-speed mixers, air-cooled pelletizers, and automatic packaging machines) to form an automatic PVC compound granulation production line, realizing the integration of feeding, sekoittamalla, plastisoimalla, puristamalla, granulating, jäähdytys, ja pakkaus, further improving production efficiency and product quality.
