Hlau xab npum stabilizers: Kho PVC ntau lawm mob & Slash nqi

RauPVC manufacturers, ntsuas qhov ua tau zoo ntawm cov khoom lag luam, cov khoom lag luam zoo, thiab kev tswj tus nqi feem ntau zoo li kev taug kev nruj-tshwj xeeb tshaj yog thaum nws los txog rau cov stabilizers. Thaum cov tshuaj lom neeg hnyav-hlau stabilizers (piv txwv li, txhuas ntsev) pheej yig, lawv muaj feem xyuam rau kev tswj hwm kev txwv thiab qhov tsis zoo. Cov kev xaiv hwm zoo li organotin ua haujlwm zoo tab sis tawg lub txhab nyiaj. Nkag mushlau xab npum stabilizers- lub hauv paus nruab nrab uas daws cov mob taub hau tseem ceeb thiab khaws cov nqi hauv daim tshev.

Muab los ntawm fatty acids (xws li, stearic acid) thiab hlau xws li calcium, zinc, barium, los yog magnesium, cov stabilizers no muaj ntau yam, eco-friendly, thiab haum rau PVC cov ntsiab lus mob feem ntau. Cia peb dhia dej mus rau hauv yuav ua li cas lawv kho cov teeb meem kev tsim khoom thiab txiav cov nqi - nrog cov kauj ruam ua tau zoo rau koj lub Hoobkas.

Ntu 1: Hlau Soap Stabilizers daws 5 qhov teeb meem tseem ceeb ntawm kev tsim khoom

PVC ntau lawm ua tsis tiav thaum cov stabilizers tsis tuaj yeem ua raws li kev ua kom sov, kev xav tau kev sib raug zoo, lossis cov cai tswj hwm. Cov xab npum hlau hais txog cov teeb meem no ua rau lub taub hau, nrog cov hlau sib txawv sib xyaw tsom rau cov ntsiab lus mob tshwj xeeb.

Teeb meem 1:“Peb PVC yellows los yog tawg thaum lub sij hawm high-kub ua“

Thermal degradation (siab tshaj 160 ° C) yog PVC tus yeeb ncuab loj tshaj plaws-tshwj xeeb tshaj yog nyob rau hauv extrusion (cov kav dej, profiles) los yog calendering (artificial tawv, films). Cov tshuaj ib txwm ua rau ib leeg-hlau stabilizers (piv txwv li, zinc soap ntshiab) feem ntau overheat, ua rau "zinc burning" (dub me ntsis) los yog brittleness.

Tshuaj: Calcium-Zinc (Ca-Zn) Soap Blends
Ca-Zn hlau soapsyog cov qauv kub rau thermal stability tsis muaj hlau hnyav. Nov yog vim li cas lawv ua haujlwm:

• Calcium ua raws li "tso cua sov", uas ua rau PVC dehydrochlorination qeeb (lub hauv paus ua rau daj).

• Zinc neutralizes teeb meem hydrochloric acid (HCl) tso tawm thaum cua sov.

• Blended kom raug, lawv tiv taus 180-210 ° C rau 40+ feeb - zoo meej rau PVC tawv (qhov rais profiles) thiab mos PVC (vinyl flooring).

Tswv yim tswv yim:Rau cov txheej txheem kub (piv txwv li, PVC yeeb nkab extrusion), ntxiv 0.5-1%calcium stearate+ 0.3-0.8%zinc stearate(tag nrho 1-1.5% ntawm PVC resin hnyav). Qhov no ua rau cov ntsev ntsev 'kev ua haujlwm thermal thiab tsis txhob muaj tshuaj lom.

Teeb meem 2:“Peb cov PVC muaj cov dej ntws tsis zoo - peb tau txais huab cua npuas lossis tuab tuab“

PVC xav tau kev khiav zoo thaum lub sij hawm molding lossis txheej kom tsis txhob muaj qhov tsis xws luag xws li pinholes lossis qhov ntsuas tsis sib haum. Pheej yig stabilizers (xws li, yooj yim magnesium xab npum) feem ntau thicken lub yaj, cuam tshuam kev ua.

Kev daws: Barium-Zinc (Ba-Zn) Soap Blends
Ba-Zn hlausoaps zoo heev ntawm kev txhim kho cov dej ntws vim:

• Barium txo cov viscosity yaj, cia PVC kis tusyees nyob rau hauv pwm los yog calenders.

• Zinc boosts thermal stability, yog li txhim kho ntws tsis tuaj ntawm tus nqi degradation.

Qhov zoo tshaj plaws rau:Cov ntawv thov PVC mos zoo li cov hoses hloov tau yooj yim, rwb thaiv tsev cable, lossis tawv tawv. Ib tug Ba-Zn blends (1-2% ntawm resin hnyav) txiav cov pa npuas los ntawm 30-40% piv rau magnesium soaps.

Pro Hack:Sib tov nrog 0.2-0.5% polyethylene wax los txhim kho kev ntws mus ntxiv-tsis xav tau cov khoom siv kim heev.

Teeb meem 3:“Peb ua tau't siv PVC rov ua dua vim tias cov stabilizers sib tsoo nrog cov muab tub lim“

Ntau lub chaw tsim khoom xav siv PVC rov ua dua tshiab (kom txo cov nqi) tab sis tawm tsam nrog kev sib raug zoo: cov khoom siv rov ua dua feem ntau muaj cov khoom seem (piv txwv li, calcium carbonate) los yog cov yas uas ua rau cov stabilizers, ua rau huab cua los yog brittleness.

Tshuaj: Magnesium-Zinc (Mg-Zn) Soap Blends
Mg-Zn hlau soaps yog ultra-compatible nrog recycled PVC vim:

• Magnesium tiv thaiv cov tshuaj tua kab mob xws li CaCO₃ lossis talc.

• Zinc tiv thaiv rov qab degradation ntawm cov qub PVC chains.

Qhov tshwm sim:Koj tuaj yeem muab 30-50% rov ua dua PVC rau hauv cov khoom tshiab yam tsis muaj kev poob zoo. Piv txwv li, cov chaw tsim khoom siv yeeb nkab siv Mg-Zn xab npum txo tus nqi nkauj xwb los ntawm 22% thaum ua tau raws li cov qauv ASTM.

Teeb meem 4:“Peb cov khoom siv PVC sab nraum zoov tawg lossis ploj hauv 6 lub hlis“

PVC siv rau lub vaj hoses, rooj tog sab nraum zoov, los yog sab xav tau UV thiab huab cua tsis kam. Tus qauv stabilizers tawg nyob rau hauv tshav ntuj, ua rau kev laus ntxov ntxov.

Kev daws: Calcium-Zinc + Tsis tshua muaj ntiaj teb hlau xab npum sib xyaw
Ntxiv 0.3-0.6% lanthanum los yog cerium stearate (tsis tshua muaj hlau soaps) rau koj Ca-Zn blend. Cov no:

• Absorb UV hluav taws xob ua ntej nws ua rau PVC molecules puas.

• Ncua sij hawm sab nraum zoov ntawm 6 lub hlis mus rau 3+ xyoo.

Nqi Win:Tsis tshua muaj lub ntiaj teb soaps raug nqi tsawg dua cov khoom tshwj xeeb UV absorbers (xws li, benzophenones) thaum xa cov kev ua tau zoo sib xws.

Teeb meem 5:“Peb tau txais kev tsis lees paub los ntawm EU cov neeg yuav khoom rau cov khoom txhuas / cadmium“

Cov kev cai thoob ntiaj teb (REACH, RoHS, California Prop 65) txwv cov hlau hnyav hauv PVC. Hloov mus rau organotin yog kim, tab sis hlau soaps muaj lwm txoj hauv kev.

Kev daws: Tag nrho cov hlau xab npum sib xyaw (tsis muaj hlau hnyav)

•Ca-Zn, Ba-Zn, thiabMg-Zn xab npumyog 100% txhuas / cadmium-dawb.

• Lawv ua tau raws li REACH Annex XVII thiab US CPSC cov qauv - tseem ceeb rau kev lag luam xa tawm.

Pov thawj:Tuam Tshoj PVC zaj duab xis chaw tsim tshuaj paus tau hloov los ntawm cov ntsev ntsev mus rau Ca-Zn xab npum thiab tau txais EU kev lag luam hauv 3 lub hlis, nce kev xa tawm los ntawm 18%.

Ntu 2: Yuav Ua Li Cas Hlau Soap Stabilizers Txiav Nqi (3 Cov Tswv Yim Ua Tau Zoo)

Stabilizers feem ntau ua rau 1-3% ntawm cov nqi tsim khoom PVC - tab sis kev xaiv tsis zoo tuaj yeem ua ob npaug ntawm cov nqi pov tseg, rov ua dua, lossis nplua. Hlau soaps optimize tus nqi nyob rau hauv peb txoj kev tseem ceeb:

1. Slash Raw Khoom Nqi (Txog 30% Pheej Yig Tshaj Organotin)

• Organotin stabilizers raug nqi $8–$12/kg; Ca-Zn hlau soaps raug nqi $4–$6/kg.

• Rau lub Hoobkas tsim 10,000 tons ntawm PVC / xyoo, hloov mus rau Ca-Zn txuag tau ~ $ 40,000– $ 60,000 ib xyoos ib zaug.

• Tswv yim: Siv cov xab npum "ua ntej sib xyaw" hlau (cov neeg muab khoom sib xyaw Ca-Zn / Ba-Zn rau koj cov txheej txheem tshwj xeeb) kom tsis txhob yuav ntau dhau ntawm cov khoom siv ib leeg.

2. Txo cov nqi seem ntawm 15–25%

Hlau soaps 'zoo thermal stability thiab compatibility txhais tau tias tsawg dua batches. Piv txwv li:

• Lub Hoobkas PVC yeeb nkab siv Ba-Zn xab npum txiav cov seem ntawm 12% mus rau 7% (txuag ~ $ 25,000 / xyoo ntawm resin).

• Cov khoom siv yas pem teb siv Ca-Zn xab npum tshem tawm "daj ntug" qhov tsis xws luag, txo lub sijhawm ua haujlwm rov qab los ntawm 20%.

Yuav ntsuas li cas:Taug qab cov nqi seem rau 1 lub hlis nrog koj cov stabilizer tam sim no, tom qab ntawd sim cov xab npum hlau - feem ntau cov chaw tsim khoom pom kev txhim kho hauv 2 lub lis piam.

3. Ua kom zoo npaum li cas (Siv tsawg, Tau Ntau)

Cov xab npum hlau muaj txiaj ntsig zoo dua li cov tshuaj stabilizers, yog li koj tuaj yeem siv me me:

• Lead ntsev xav tau 2-3% ntawm resin hnyav; Ca-Zn blends tsuas yog xav tau 1-1.5%.

• Rau kev ua haujlwm 5,000-tuj / xyoo, qhov no txo ​​qis kev siv stabilizer los ntawm 5–7.5 tons / xyoo ($ 20,000– $ 37,500 hauv kev txuag).

Dosage Test Hack:Pib nrog 1% hlau xab npum, ces nce 0.2% nce mus txog thaum koj ntaus koj lub hom phiaj zoo (xws li, tsis muaj daj tom qab 30 feeb ntawm 190 ° C).
