Puas yog PPR Pipe Toxic?

PPR yeeb nkab puas lom?

Thaum nws los txog rau kev xaiv cov kav dej rau cov dej thiab cov kav dej, ntau tus tswv tsev thiab cov neeg cog lus tau nyiam siv cov kav dej PPR. PPR sawv cev rau polypropylene random copolymer, thiab nws yog ib hom yas uas tau siv dav hauv Tebchaws Europe thiab Asia rau ntau tshaj ob xyoo lawm.

Ib lo lus nug uas feem ntau tshwm sim thaum xav txog cov kav dej PPR yog seb lawv puas muaj tshuaj lom. Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov kev nyab xeeb ntawm cov kav dej PPR thiab tshuaj xyuas cov xwm txheej uas tuaj yeem ua rau muaj kev txhawj xeeb txog kev mob toxicity.

PPR yeeb nkab muaj pes tsawg leeg thiab kev tsim khoom

Ua ntej peb tshawb xyuas cov tshuaj lom ntawm cov kav dej PPR, nws yog ib qho tseem ceeb kom nkag siab tias lawv yog dab tsi, thiab lawv tsim tau li cas. PPR cov kav dej yog tsim los ntawm cov khoom siv thermoplastic hu ua polypropylene, uas yog ib hom yas uas tau siv dav hauv kev lag luam ntim khoom, nrog rau kev tsim khoom, khoom siv hauv tsheb, thiab lwm yam khoom siv.

Ua PPR kav dej, polypropylene yog tov nrog ib hom tshwj xeeb ntawm random copolymer, uas muab cov kav dej rau lawv cov khoom tshwj xeeb. Cov copolymer no tau ntxiv rau cov khoom siv raw thaum lub sij hawm extrusion txheej txheem, uas yuav tsum melting cov yas thiab molding nws mus rau hauv cov duab xav tau.

Thaum lub sij hawm extrusion txheej txheem, cov khoom siv PPR yog tov nrog additives, xws li stabilizers thiab pigments, los txhim kho nws cov xim thiab txhim kho nws tiv taus tshav kub thiab UV hluav taws xob. Qhov kawg tshwm sim yog qhov muaj zog, ruaj khov, thiab kav ntev ntev uas siv tau rau ntau yam kev siv.

Cov yam ntxwv uas tuaj yeem ua rau muaj kev txhawj xeeb toxicity

Thaum PPR cov kav dej tau siv nyab xeeb hauv Tebchaws Europe thiab Asia tau ntau xyoo, muaj qee yam uas tuaj yeem ua rau muaj kev txhawj xeeb txog kev mob toxicity. Cov no suav nrog:

1. Raw khoom zoo: Qhov zoo ntawm polypropylene thiab copolymer siv nyob rau hauv cov txheej txheem tsim khoom tuaj yeem cuam tshuam cov toxicity ntawm cov khoom tiav. Yog tias cov khoom siv raw muaj impurities lossis cov khoom tsis huv, nws tuaj yeem ua rau cov khoom muaj kuab lom.

2. Cov txheej txheem tsim khoom: Cov txheej txheem extrusion siv los ua PPR cov kav dej kuj tuaj yeem cuam tshuam rau lawv cov toxicity. Yog tias lub tshuab tsis raug tswj xyuas kom zoo lossis tsis ua haujlwm nyob rau hauv qhov kub thiab txias, nws tuaj yeem ua rau muaj cov pa phem.

3. Kev siv cov khoom siv ntxiv: Thaum cov khoom siv ntxiv yog siv los txhim kho kev ua haujlwm ntawm cov kav dej PPR, qee cov khoom siv ntxiv tuaj yeem ua rau muaj kev txhawj xeeb txog toxicity. Piv txwv li, yog siv lead-raws li pigments, nws tuaj yeem ua rau cov khoom muaj kuab lom.

4. Kev teeb tsa: Cov txheej txheem kev teeb tsa ntawm cov kav dej PPR tuaj yeem cuam tshuam rau lawv txoj kev nyab xeeb. Yog tias cov kav dej tsis raug ntsia tau zoo, nws tuaj yeem ua rau cov xau uas tuaj yeem tso cov tshuaj lom mus rau hauv ib puag ncig.

PPR yeeb nkab kev nyab xeeb

Txawm hais tias muaj peev xwm ua rau muaj kev txhawj xeeb txog toxicity, PPR kav feem ntau suav hais tias muaj kev nyab xeeb rau kev siv cov kav dej. Qhov no yog vim muaj cov hauv qab no:

1. Tsawg toxicity: PPR yog cov khoom toxicity tsawg, uas txhais tau hais tias nws tsis tso cov tshuaj phem rau hauv ib puag ncig. Qhov no yog vim li cas cov kav dej PPR tau siv dav hauv kev ntim khoom noj.

2. Kev tiv thaiv tshav kub thiab UV hluav taws xob: PPR kav dej tiv taus kub thiab UV hluav taws xob, uas ua rau lawv zoo tagnrho rau kev siv hauv cov kav dej. Qhov no kuj txhais tau tias lawv yuav tsis tawg lossis degrade thaum lub sijhawm, uas tuaj yeem tso cov tshuaj lom mus rau hauv ib puag ncig.

3. Lub neej ntev: PPR cov kav dej muaj lub neej ntev, uas txhais tau hais tias lawv tsis tas yuav tsum tau hloov ntau zaus raws li lwm cov khoom siv kav. Qhov no txo ​​qhov kev pheej hmoo ntawm cov tshuaj lom neeg raug tso tawm los ntawm cov kav dej thaum lub sijhawm hloov txheej txheem.

4. Tsis-corrosive: PPR kav dej tsis muaj corrosive, uas txhais tau hais tias lawv yuav tsis tawg thaum lub sij hawm thiab tso cov tshuaj phem rau hauv ib puag ncig.

Xaus

Thaum nws los txog rau kev xaiv cov kav dej, PPR kav dej feem ntau suav hais tias muaj kev nyab xeeb rau kev siv dej thiab kev siv dej. Thaum muaj tej yam tseem ceeb uas tuaj yeem ua rau muaj kev txhawj xeeb txog kev mob toxicity, tsis tshua muaj toxicity ntawm cov khoom, tiv thaiv tshav kub thiab UV hluav taws xob, lub neej ntev, thiab cov khoom tsis muaj corrosive ua rau cov kav dej PPR yog qhov kev xaiv zoo rau cov tswv tsev thiab cov neeg cog lus ib yam nkaus.

Raws li nrog rau txhua yam khoom siv kav dej, kev teeb tsa thiab kev saib xyuas kom zoo yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kav dej PPR. Los ntawm kev ua raws li cov kev coj ua zoo tshaj plaws, thiab siv cov khoom siv kav dej zoo thiab cov kws tshaj lij kev teeb tsa, cov tswv tsev tuaj yeem tso siab tau tias lawv cov kav dej muaj kev nyab xeeb thiab ua haujlwm zoo.
