Cov yeeb nkab yas yog ib qho khoom siv raj xa khoom uas tau siv dav hauv ntau thaj teb vim nws cov yas, tus nqi qis, teeb liab, thiab corrosion tsis kam. Cov hauv qab no yog ntau hom yeeb nkab yas xws li lawv cov ntawv thov thiab cov luag haujlwm:
PVC yeeb nkab:Polyvinyl chloride (PVC) Yeeb yog ib qho ntawm cov roj yeeb feem ntau thiab cov pa dej, siab tiv thaiv, zoo seasing, tsawg tus nqi, tsawg tus nqi, tus nqi qis, thiab lwm yam.
Pe Yeeb:Polyethylene (PE) Yeeb yog ib qho khoom siv cov khoom siv, roj av, thiab cov dej phwj, kev ua kom haum corrosion, zoo hloov, thiab lwm yam.
PP-R YEEB:Polypropylene RANDOM RANDO RANDOLLER (PP-R) Cov Yeeb Nkab tuaj yeem siv rau sab hauv tsev muaj cov pa dej hauv tsev, acid, thiab alkali, tsis yooj yim rau nplai, thiab lwm yam.
ABS Yeeb:ABS yeeb nkab yog qhov cuam tshuam-resistant, corrosion-resistant piping kho, ua noj chav dej phwj, thiab lwm daim teb.
Pc Yeeb Nkab:Polycarbonate (PC) cov yeeb nkab muaj lub zog siab, siab pob tshab, thiab lwm yam ntxwv, thiab tuaj yeem siv rau hauv txoj kev loj, kev tsim kho, thiab lwm yam kev tsim kho.
Pa Yeeb:Polyamide (PA) cov yeeb nkab feem ntau yog siv hauv kev ua pa ntawm huab cua, dej, thiab lwm yam dej-tiv taus, kub-resistant, siab tiv taus, thiab lwm yam ntxwv.
Cov khoom sib txawv yas yog qhov haum rau cov teb sib txawv. Feem ntau, kav yas muaj qhov zoo ntawm kev ua ib txwm muaj, thiab maj mam hloov cov tsoos hlau ib txwm muaj, thiab ua haujlwm tseem ceeb hauv kev tsim kho niaj hnub no.
Txawm li cas los xij, qee cov teeb meem sib txawv tuaj yeem ntsib thaum muaj kev tsim khoom thiab kev tsim cov kav yas, suav nrog:
Tsis zoo yaj kua txiv ntoo:Qee cov ntaub ntawv yas roj nyoos hauv cov txheej txheem ua, vim molecular saw qauv, ua rau tsis ncaj ncees thiab txhaj tshuaj molding ua zoo, thiab lwm yam teeb meem.
Cov tsis muaj zog ruaj khov stability:Qee cov ntaub ntawv yas raw hauv kev ua cov khoom lag luam thiab cov cua txias ua kom tawg, yooj yim coj mus rau cov khoom txom nyem ruaj khov ntawm cov khoom tiav ntawm cov khoom tiav, lossis txawm tias muaj teeb meem ntxiv.
Tsis zoo nto zoo:Nyob rau hauv cov txheej txheem ntawm extrusion los yog txhaj tshuaj molding ntawm cov pwm, thiab nws yuav ua rau muaj kev tsis sib xws, thiab nws tuaj yeem, thiab lwm yam. Nyob rau saum npoo ntawm cov khoom tiav.
Cov kub kub tsis kam:Qee cov ntaub ntawv yas raw zoo li ua muag thiab deform thaum muaj kev kub siab, uas tej zaum yuav yog ib qho teeb meem rau cov ntawv siv yeeb nkab uas yuav tsum tau tiv thaiv qhov chaw kub siab.
Lub zog tsis txaus:Qee cov ntaub ntawv yas raw tsis muaj lub zog siab, ua rau nws nyuaj kom tau raws li qhov yuav tsum tau ua rau lub zog tensile hauv qee cov kev siv engineering hauv qee cov kev siv engineering hauv qee cov ntawv thov engineering.
Cov teeb meem no feem ntau daws tau los ntawm kev txhim kho cov khoom siv raw ua qauv, kev ua kom zoo dua cov txheej txheem, thiab txhim kho cov txheej txheem pwm. Nyob rau tib lub sijhawm, nws tseem ua tau ntxiv cov neeg sawv cev tshwj xeeb ntxiv, cov sau ua ke los txhim kho kev ua haujlwm yas thiab qhov zoo ntawm cov khoom tiav. Tau ntau xyoo, PPA (polymer ua additive) fluoropolymer ua AID tau raug xaiv los ntawm cov yeeb nkab tsim los raws li cov roj ci.
PPA (polymer ua ntxiv) fluoropolymer Ua cov tshuaj ntxiv hauv cov khoom lag luam, txhim kho cov nqi ua tiav, thiab txo cov nqi tsim khoom. Feem ntau muaj nyob rau hauv daim ntawv ntawm cov kua roj ntshav, thiab muaj peev xwm ua kom zoo txo cov kev sib txhuam thiab cov khoom lag luam zoo nyob rau hauv extrusion lossis txhaj tshuaj molding txheej txheem.
Thoob ntiaj teb, pfas tseem dav siv nyob rau hauv ntau cov ntawv thov thiab cov neeg siv khoom siv, tab sis nws txoj kev txaus ntshai tau ua rau muaj kev txhawj xeeb thoob plaws. Nrog rau kev ua haujlwm tshuaj European (cha) Ua Daim Ntawv Sau Xov Xwm Pfas txwv pej xeem hauv 2023, muaj ntau cov tuam ntxhab tau pib nrhiav lwm txoj hauv kev rau PPA fluoropolymer ua AIDS.
Teb rau kev ua lag luam xav tau nrog cov kev daws teeb meem tshiab - silike xa tawmPfas-dawb polymer ua pab (PPA)
Hauv kev teb rau cov qauv ntawm lub sijhawm, site R & D pab pawg tau nqis peev ntau ntawm kev siv zogPfas-dawb polymer ua pab pab (ppas)Siv cov txheej txheem thev naus laus zis tshiab thiab kev xav tshiab, ua kom tau txais txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom muaj kev tiv thaiv ib puag ncig.
Silike Fluorine-Free PPAZam kev phom sij ib puag ncig thiab kev noj qab haus huv cuam tshuam nrog kev ua liaj ua teb pfas thaum ua kom muaj kev ua tiav kev ua tau zoo thiab cov khoom zoo.Silike Fluorine-Free PPATsis tsuas yog ua raws li daim qauv pfas txwv luam tawm los ntawm cha tab sis tseem yuav muab txoj kev nyab xeeb thiab txhim khu kev qha rau cov tsoos PFA sib txuas.
Silike Fluorine-Free PPAyog pfas-dawb polymer ua pab (PPA) los ntawm silike. Cov kev ntxiv yog cov khoom siv polysiloxane cov khoom siv uas lubrication ntawm cov pab pawg hloov kho kom raug tsiv mus thiab ua raws li cov khoom siv ua thaum ua tiav.
Silike fluorine-dawb ppa tuaj yeem yog hloov chaw zoo tshaj plaws rau cov tshuaj fluorine raws li ppa ua pab. Ntxiv me me ntawmSilike Fluorine-Dawb PPA silimer 5090,Silimer 5091Muaj peev xwm txhim kho cov rhuab fluin, txheej txheem, cov khoom siv ntawm kev sib txhuam, thiab txhim kho cov txiaj ntsig thiab cov khoom lag luam zoo thaum ib puag ncig phooj ywg thiab muaj kev nyab xeeb.
Lub luag haujlwm ntawmSilike fluorine-free PPA silimer 5090Hauv kev tsim cov khoom yas:
Txo ntawm sab hauv thiab txheej txheejQhov sib txawv: Hauv cov txheej txheem Extrusion ntawm cov kav dej, qhov sib txawv ntawm sab hauv thiab sab hauv lub diam yog qhov tseem ceeb heev. Qhov sib ntxiv ntawmSilike Fluorine-Dawb PPA silimer 5090Txo txoj kev sib txhuam ntawm cov yaj thiab cov tuag, txo qhov sib txawv thiab txheej txheem sib txawv, thiab ua kom muaj kev ruaj ntseg sab ruaj khov ntawm cov yeeb nkab.
Txhim kho nto tas:Silike Fluorine-Dawb PPA silimer 5090Zoo txhim kho saum npoo av tiav ntawm cov yeeb nkab, thiab txo cov yeeb nkab sab hauv thiab cov yeeb nkab zoo nkauj, cov yeeb nkab hauv cov yeeb nkab thiab cov kab ntsig tsawg dua.
Txhim Kho Lubricity:Silike Fluorine-Dawb PPA silimer 5090Txo lub suab viscosity thiab txhim kho cov txheej txheem txheej txheem thiab ua kom yooj yim kom ntws thiab sau cov khoom lag luam hauv kev extrusion lossis kev txhaj tshuaj molding cov txheej txheem.
Kev tshem tawm ntawm yaj breakage:Qhov sib ntxiv ntawmSilike Fluorine-Dawb PPA silimer 5090Txo cov coefficient ntawm kev sib txhuam, txo lub zog, txhim kho sab hauv thiab sab nraud lubrication, zoo tshem tawm cov neeg muab kev pabcuam ntawm cov yeeb nkab.
Txhim kho cov kev hnav tsis kam: Silike Fluorine-Dawb PPA silimer 5090Txhim kho qhov ua txhaum tsis kam ntawm cov yeeb nkab, ua rau nws haum ntau rau cov ntawv thov ua kom tsis taus.
Kev txo lub zog noj:Ua tsaug rau nws lub peev xwm los txo qis melt viscosity thiab kev txhuam tawm,Silike Fluorine-Free PPATxo kev siv hluav taws xob kev ua kom tiav lossis txhaj tshuaj tiv thaiv cov nqi ntau lawm.
Silike Fluorine-Free PPAMuaj ntau cov ntawv thov, tsis yog rau cov leeg tab sis kuj rau cov xov hlau thiab cable, motalrocene polypropylene (MPE), thiab ntau dua. Txawm li cas los xij, cov ntawv thov tshwj xeeb yuav tsum tau hloov kho thiab kho kom zoo raws li cov ntaub ntawv sib txawv thiab kev tsim khoom. Yog tias koj muaj lus nug txog ib qho kev thov saum toj no, silike zoo siab siab tau txais kev nug koj, thiab peb muaj kev kub siab los tshawb nrhiav ntau yam ntawm pfas-dawb ua AIDS (PPA) nrog koj.
