Cov Lus Qhia ntawm Lub Tshuab Tshuab thiab Cov Lus Qhia Txog Kev Txhawb Ntsub 2026: Cov Lus Qhia rau Lub Tshuab PVC
SUZHOU, China, April 11, 2026 – Qhov kev sib tham txog Compounding & Extrusion Technology Exchange Forum lub caij thib ob tau ploj lawm nyob rau hauv Suzhou nyob heev April 10, uas muab tswv yim ntawm qhov chaw tsim khoom, cov neeg tsim khoom, cov neeg paub txog lwm yam khoom, thiab cov neeg tsim khoom rau hauv qhov chaw los ua kev sib tham txog kev pab ntau dua rau polymer processing. Thaum qhov kev sib tham no cov lus sib tham nyob rau hauv PVC processing technology, formulation optimization, thiab sustainable production yog qhov txaus siab rau cov neeg tsim khoom PVC chemical additives, uas muaj stabilizers, lubricants, processing aids, thiab foaming agents.
Los ntawm qhov kev sib tham no, peb tuaj yeem pom tias qhov kev sib tham tau paub zoo rau qhov tseeb ntawm kev pab ntau dua rau qhov chaw tsim khoom, tsis siv qhov kev sib tham rau ib yam khoom xwb, tab sis siv kev pab ntau dua rau compounding thiab extrusion technology.
Los ntawm qhov kev txhawj xeeb ntawm lub tsev sib xyaw, tsim cov lus nug rau qhov tseem ceeb ntawm cov lus hais thiab qhov nyuaj siab ntawm kev pab cuam rau kev pib qhov kev lag luam PVC additives.
1. Xwb & Tsis muaj txoj haujlwm: Qhov kev hloov tseem ceeb uas tsis tuaj yeem txhawm tau
Qhov tseem ceeb tshaj plaws ntawm cov lus hais yog qhov kev hloov los ntawm cov khoom siv tshuaj tsoo tshav thiab qhov kev siv cov khoom siv tshuaj tsoo tshav uas tsis muaj txoj haujlwm, tshwj xeeb yog cov khoom siv tshuaj tsoo tshav calcium-zinc (Ca-Zn) thiab cov khoom siv tshuaj tsoo tshav uas muaj tshuaj tsoo tshav.
•Cov kev tswj hwm thiab cov kev tswj hwm ntawm lub tsev sib xyaw: Cov lus hais tau qhia tias cov kev tswj hwm ntawm lub ntiaj teb (EU REACH, FDA food contact standards) thiab cov kev tswj hwm ntawm lub tsev sib xyaw rau kev pab cuam yog ua rau cov neeg siv PVC yuav tsum tshem tawm cov khoom siv tshuaj tsoo tshav uas muaj lead txhua yam. Qhov no ua rau muaj kev txhawj xeeb thiab kev txhawj xeeb rau cov khoom siv tshuaj tsoo tshav uas tsis muaj txoj haujlwm thiab muaj kev pab cuam zoo heev uas tuaj yeem sib piv lossis yooj yim dua qhov kev pab cuam ntawm cov khoom siv tshuaj tsoo tshav.
•Qhov tsis sib thooj ntawm kev tso cai: Qhov teeb meem tseem ceeb uas tau piav qhia yog kev tswj hwm qhov ntsuas ntawm kev nyuaj siab thiab kev tswj hwm li cas rau lub zog ntau ntawm kev tshuaj tshuaj ntau thiab kev tshuaj tshuaj ntau tsis muaj cov khoom uas muaj kev nyuaj siab. Qhov no tsaus rau kev xav tau cov khoom tshuaj tshuaj ntau uas muaj kev nyuaj siab, kev tswj hwm qhov ntsuas thiab kev tswj hwm qhov ntsuas—piv txwv li cov khoom tshuaj tshuaj ntau uas muaj kev nyuaj siab, kev tswj hwm qhov ntsuas thiab kev tswj hwm qhov ntsuas rau PVC pipe, profile, thiab rigid sheet.
2. Kev tswj hwm qhov ntsuas thiab kev ua haujlwm yuav tsum tau sib tw: Sib tw qhov ntsuas thiab qhov ntsuas
Cov lus piav qhia rau twin-screw thiab conical twin-screw extrusion rau PVC tau piav qhia tias cov khoom tshuaj tshuaj ntau hauv thiab hauv qab yog qhov tseem ceeb rau kev tswj hwm qhov ntsuas ntawm melt flow, txo torque, thiab tswj hwm qhov plate-out.
•Kev tswj hwm rau kev ua haujlwm ntau: Thaum cov khaub ncaws ua haujlwm ntau rau kev ua haujlwm ntau dua, cov khoom PVC yuav tsum muaj cov khoom tshuaj tshuaj ntau uas tswj hwm qhov ntsuas kom ua haujlwm zoo, kev tswj hwm qhov ntsuas zoo thiab kev tswj hwm qhov ntsuas zoo.
•Cost & Quality: Cov laus tswv yeej tau pom tias lub lubrication tsis zoo yog ua rau muaj ntau dua kev siv hluav tais, kev puas tsuaj ntawm cov khoom siv, thiab cov ntaub ntawv ntawm cov khoom. Ntawd ua rau muaj qhov tseem ceeb rau kev siv cov lubricants uas muaj peb yam (piv txwv li PE wax, fatty acid ester, complex ester) uas tau muab tsim los rau PVC extrusion uas muaj ntau filler thiab ntau throughput.
3. Cov Processing Aids Tshiab: Solving PVC’s Inherent Processing Challenges
Lub PVC muaj kev tsis zoo ntawm melt strength thiab gelation yooj yim yog qhov tseem ceeb uas cov tswv yeej tau plooj ntaus. Cov tswv yeej ntawm forum tau qhia tias:
•ACR & Processing Modifiers: Qhov tseem ceeb rau kev siv cov processing aids (piv txwv li ACR) los pab kom fusion yooj yim dua, pab kom melt zoo dua, thiab pab kom cov khoom PVC uas tsis muaj flexibility muaj cov ntaub ntawv zoo dua.
•Kev sib thaj ntau: Thaum qhov kev lag luam yuav tsum muaj cov khoom siv calcium carbonate ntau dua kom txo qhov siab ntawm cov khoom, cov khoom siv rau kev tsim khoom uas pab tso cov khoom siv rau hauv qhov chaw zoo thiab tshem cov khoom uas ua rau qhov ntxiv ntau yog tau dhau los. Ntawd yog qhov yuav tsum tau ua rau cov neeg siv khoom siv pab kev sib thaj thiab kev tso cov khoom siv rau hauv qhov chaw zoo rau cov khoom PVC uas muaj cov khoom siv ntau.
4tshuaj tshuaj rau kev tshuaj tshuaj: Qhov yuav tsum tau ua rau PVC tshuaj tshuaj thiab WPC
Qhov chaw sib thaj rau kev siv tshuaj tshuaj (AC, OBSH) thiab kev tshuaj tshuaj ntau yam hauv kev tshuaj tshuaj tshuaj tshuaj tau qhia tias muaj kev txaus siab ntau rau cov khoom PVC tshuaj tshuaj, WPC (khoom siv ntawv thiab plastic), thiab cov khoom tshuaj tshuaj tshuaj tshuaj.
•Cov qhov txhaum tseem ceeb: Tsim cov cell zoo ib yam, tshem qhov tshuaj tshuaj tshuaj, thiab tswj qhov ntxiv ntawm cov khoom.
•Rog ntawm kev ntxuav: Qhov no qhia tias yuav tsum muaj cov khoom ntxuav uas muaj kev ua haujlwm zoo, cov khoom ntxuav uas tuaj yeem suav kom tsis txhob ntxuav, thiab cov khoom ntxuav uas tuaj yeem suav kom tsis txhob ntxuav, uas ua haujlwm zoo rau hauv qhov teeb meem ntawm PVC. Qhov kev nyiaj qab rau kev siv PVC uas muaj qhov ntev ntev thiab muaj qhov ntev ntev qhia tias muaj kev xav tau ntawm cov khoom ntxuav uas muaj kev ua haujlwm zoo.
5. Kev tsim khoom tshwj xeeb thiab kev sau cov lus tshwj xeeb: Kev siv cov lus tshwj xeeb uas muaj kev sib piv
Qhov kev sib tham no muaj kev xav txog AI, kev sib tham ntawm kev ua haujlwm, thiab DOE (Kev sau cov lus tshwj xeeb) rau kev ua haujlwm kom zoo dua, qhia tias muaj kev hloov mus rau kev tsim khoom tshwj xeeb.
•Cov neeg tsim khoom xav tau kev paub tseeb: Cov neeg tsim khoom hauv qab xav tau siv cov lus tshwj xeeb los xaiv cov khoom ntxuav uas paub tseeb tias yuav muaj kev ua haujlwm zoo, txo cov khoom tsis zoo, thiab ua kom kho khoom ntau dua.
•Cov neeg siv cov khoom tshuaj ntxiv yuav tsum npaj: Vim li no, cov neeg tsim cov khoom tshuaj ntxiv PVC yuav tsum muab cov lus qhia txog cov khoom, cov lus qhia txog qhov ntau ntau uas yuav tsum siv, thiab cov lus qhia txog qhov sib xws los ntawm cov khoom tshuaj ntxiv rau hauv cov kev ua haujlwm ntawm cov fabrik tshiab. Cov khoom tshuaj ntxiv uas yuav tsum npaj raws li kev xav thiab muaj kev suav tau yuav muaj qhov zoo dua.
6. Qhov kev tswj hwm ntawm kev sib cuam tshuam thiab PVC uas tau pov tseg (RPVC)
Cov hais txog kev nyab xeeb tau qhia tias kev pov tseg PVC raws li kev pov tseg meej tshaj plaws.
•Qhov txhaum: PVC uas tau pov tseg nrog lub caij ntev yuav tsum muaj qhov nyab xeeb ntawm kev sov thiab qhov tshuaj ntxiv yuav tsum muaj qhov sib xws tsis zoo.
•Cov khoom tshuaj ntxiv ua rau qhov txhaum: Qhov no tsim qhov kev tswj hwm tshiab rau cov khoom tshuaj ntxiv uas pab pov tseg, cov khoom tshuaj ntxiv uas pab ua dua, thiab cov khoom tshuaj ntxiv uas pab ua kom sib xws, uas pab ua kom PVC uas tau pov tseg tau zoo dua, thiab ua rau nws tuaj yeem ua dua rau cov khoom uas tau ua los ntawm kev tshuaj ntxiv uas muaj qhov zoo tshaj plaws.
Cov khoom tshuaj ntxiv yog qhov tseem ceeb rau kev ua haujlwm tshuaj ntxiv
Cov kev sib tham ntawm 2026 Compounding & Extrusion Forum tau qhia tias cov khoom siv PVC chemical additives yog cov khoom tseem ceeb uas tsis tuaj yeem tshuav los ntawm kev sib xyaw thiab kev txhawj xeeb polymer uas zoo, muaj peev xwm thiab sib koom ua ke. Qhov kev txhawj xeeb ntawm lub rooj plaub rau kev ua haujlwm ntau dua, muaj qhov zoo dua, nyob ib leeg rau cov kev lag luam ntawm lub siab thiab kev sib koom ua ke yog tsis yog qhov txhaum xwb—nws yog qhov yuav tsum tau ua kom zoo heev rau cov neeg siv khoom siv uas muaj kev ntxiv ntxiv.
Rau cov thawj coj uas nyob ntawm kev sib xyaw stabilizers, lubricants, processing aids, thiab foaming agents, cov lus qhia yog tsis muaj kev cuam tshuam: kev ua tau zoo yog rau cov neeg uas tsim cov khoom siv uas muaj kev sib xyaw, muaj peev xwm siab thiab tsis muaj txhais, uas tau pab txaus rau cov teeb meem txheej txheem uas tau pab txaus rau cov kev sib tham no. Thaum kev txhawj xeeb ntawm extrusion technology yuav ntxiv ntxiv, cov khoom siv yuav tsum ntxiv ntxiv ib leeg, ua rau cov khoom siv PVC thib ob yog qhov tseem ceeb uas pab tau.
