Niaj hnub no, cov neeg siv khoom feem ntau xaiv siv cov kav dej PPR thaum kho lawv lub tsev. Txawm li cas los xij, muaj ntau hom PPR kav muag hauv khw muag khoom. Tsis tsuas yog lawv sib txawv ntawm cov xim thiab thickness, tab sis kuj cov dej num qhia los ntawm lub khw kuj txawv. Yog li PPR yeeb nkab twg yog qhov zoo rau kev txhim kho cov kav dej hauv tsev? Niaj hnub no, Xiaobian yuav muab koj cov kev paub me ntsis ntawm PPR cov kav dej.
PPR yeeb nkab yog ib hom kev tsim yeeb nkab extruded los ntawm random copolymer polypropylene raw khoom los ntawm cov khoom siv yeeb nkab extrusion. , Feem ntau, muaj ntau hom thiab hom PPR cov kav dej rau kev txhim kho hauv tsev, thiab lawv muaj ntau qhov nyuaj. Tsis tsuas yog nws nyuaj rau kev paub qhov zoo ntawm qhov tsis zoo ntawm qhov tsos, tab sis kuj muaj nyob hauv kev ua haujlwm, muaj cov kav dej tua kab mob, cov kav dej tiv thaiv kab mob, cov kav dej tsis zoo, thiab txawm tshaj tawm los tiv thaiv oxidation. Muaj ntau hom kav dej uas lub hlwb nco tsis tau.
Ua ntej tshaj plaws, tus editor yuav piav qhia qhov txawv ntawm PPR cov kav dej los ntawm qhov pom. Kev txhim kho hauv tsev PPR cov kav dej hauv khw muaj cov xim sib txawv thiab cov kev qhia tshwj xeeb. Peb yuav tsum xaiv li cas? Qhov tseeb, tsis tas yuav txhawj txog qhov tsos. Tsis muaj qhov sib txawv ntawm cov txheej txheem tsim khoom thiab kev ua haujlwm ntawm PPR raj ntawm cov xim sib txawv. Nws tsuas yog hais tias cov khoom sib txawv ntawm cov xim sib txawv tau ntxiv rau hauv kev tsim cov raj, thiab cov xim sib txawv. Yog tias koj nyiam, koj tuaj yeem yuav cov xim koj nyiam. Tom qab tag nrho, nyiaj yog ib qho nyuaj rau yuav. Kuv kam hais rau tsis muaj dab tsi. Nws yuav tsum tau muab sau tseg ntawm no. Muaj peb lub kav dej ntsuab hauv tsev txhim kho PPR cov kav dej, ib qho yog cov yeeb nkab ntsuab ntsuab (tseem tsaus), thiab lwm yam yog xim dawb thiab ntsuab Lub raj xa dej hauv tsev ob txheej (dawb rau sab nraud thiab ntsuab sab hauv, tuaj yeem ntsia tau rau sab nraud), thiab lwm qhov yog lub raj ntsuab-dawb antibacterial tube (lub luag haujlwm ntawm cov xim dawb ntawm sab hauv thiab ntsuab sab nraud tuaj yeem muab zais thiab tuaj yeem ntsia tau rau ntawm qhov chaw).
Qhov thib ob, kev txhim kho hauv tsev PPR cov kav dej tsis tas yuav tsum muaj ntau txoj haujlwm, tsuav yog nws yog cov khoom lag luam hauv lub tebchaws, muaj cov lus hais txog kev noj qab haus huv, thiab muaj cov dej ntws ua haujlwm, thiab tom qab ntawd hloov kho qee qhov yog tias cov kav dej muaj antibacterial muaj nuj nqi, uas tuaj yeem paub txog cov dej haus zoo ntawm tsev neeg. Kev cuam tshuam, tiv thaiv oxidation, thiab tiv thaiv khov yog txhua yam virtual thiab tsis tsim nyog. Qee tus neeg hais tias PPR cov kav dej hauv thaj tsam txias ntawm sab qaum teb yuav tsum muaj qhov muaj zog tiv taus. Qhov ntawd yog ua tsis tau. Cov khoom siv tshuaj ntawm cov khoom siv raw ntawm cov yeeb nkab dej PPR txiav txim siab tias nws tsis muaj Frost tsis kam. Qhov kub thiab txias, qhov qis dua qhov toughness ntawm PPR yeeb nkab thiab rigidity. Lub zog nws yog, nws yog nkig, thiab nws yuav tsim ib tug linear tawg raws li qhov cuam tshuam qhov taw tes nyob rau hauv qhov kev cuam tshuam ntawm ib qho khoom tawv los yog nyob rau hauv cov xwm txheej ntawm kev tsis sib xws.
