YU thiab PVC Ob leeg yog ib hom yas, lawv ua cov khoom hauv peb lub neej yog ib qho uas pom ntau heev, thiab feem ntau, ob yam khoom no kuj hloov tau ib leeg, yog li ntau tus neeg tsis tuaj yeem qhia qhov txawv ntawm lawv, yog li hnub no peb yuav qhia luv luv txog EVA, PVC yog cov khoom siv dab tsi, EVA thiab PVC yog dab tsi zoo.
Cov khoom EVA
Lub npe tshuaj ntawm EVA yog ethylene - vinyl acetate copolymer, yog ib qho polymer, nws cov mis molecular yog (C2H4)x.(C4H6O2)y, muaj kev kub hnyiab, tom qab hlawv yuav tsim cov pa roj carbon monoxide thiab carbon dioxide. Nws muaj kev tiv thaiv kev laus zoo, tiv thaiv dej, tiv thaiv ozone thiab kev ruaj khov tshuaj lom neeg. EVA muaj cov yam ntxwv hauv qab no.
1, Tiv thaiv kev co: Nws muaj kev rov qab thiab kev tiv thaiv siab rau kev nruj, zoo toughness, yog li nws yog ib qho khoom siv tiv thaiv kev co thiab cushioning zoo heev.
2, suab rwb thaiv tsev uas tsis muaj dej: nws yog ib lub qauv kaw npuas, yuav tsis nqus dej, cov dej noo-pov thawj, suab rwb thaiv tsev kuj zoo heev.
3, rwb thaiv tsev kub: cov qauv npuas ua rau EVA kuj muaj cov khoom rwb thaiv tsev kub thiab rwb thaiv tsev kub zoo heev.
4, yooj yim ua: EVA tsis muaj qhov sib txuas ruaj khov, kub nias, txiav, laminating ua tiav yooj yim heev.
5, kev tiv thaiv corrosion: EVA nws tus kheej antibacterial, tsis muaj tshuaj lom thiab tsis muaj saj, tsis muaj kuab paug, muaj kev tiv thaiv zoo rau acid thiab alkali corrosion.
Daim Ntawv Thov: Cov khoom siv EVA tuaj yeem ua rau cov khoom siv khau, zaj duab xis, hlau thiab cable, cov khoom ua si, cov nplaum kub yaj, EVA emulsion thiab lwm yam khoom.
Properties ntawm PVC
Lub npe tshuaj ntawmPVCyog polyvinyl chloride, nws yog ib qho hmoov dawb nrog ib qho qauv amorphous thiab tsis ruaj khov rau lub teeb thiab cua sov. Yog tias nws raug tshav ntuj ntau zaus, lossis yog tias nws nyob ntawm 100 ° C, nws yuav lwj thiab tsim hydrogen chloride, uas kuj yuav ua rau muaj xim tsis zoo thiab nws cov khoom siv kho tshuab yuav raug txo qis vim li ntawd. Qhov kub siv feem ntau yog ntawm -15 degrees thiab 55 degrees. Thaum siv cov ntaub ntawv PVC, qee cov stabilizers yuav tsum tau ntxiv rau lawv.
Daim Ntawv Thov: PVC yog siv rau ntau yam kev siv, hauv cov ntaub ntawv siv hauv kev tsim kho, cov khoom lag luam, cov khoom siv niaj hnub, cov vuas pem teb, tawv cuav, tawv pem teb, cov xov hlau thiab cov xov hlau, cov yeeb yaj kiab ntim khoom, cov fwj yas, cov ntaub ntawv ua npuas ncauj, cov fibers, thiab lwm yam.
Properties ntawm PVC
1. Nws muaj cua zoo thiab tsis nkag tau, thiab nws lub zog kuj siab heev.
2, Lub teeb yuag: PVC tsim cov khoom xws li cov kav dej, uas yog qhov sib dua hauv qhov zoo thiab yooj yim rau kev thauj khoom thiab tshem tawm.
3, cov khoom rwb thaiv tsev zoo, PVC feem ntau siv rau hauv kev tsim cov hlau thiab cable yas npog.
4, tsis cuam tshuam rau qhov zoo ntawm dej: qhov kev kuaj xyuas, PVC yeeb nkab thiab cov khoom siv, yuav tsis cuam tshuam rau qhov zoo ntawm dej, yog cov yeeb nkab zoo tshaj plaws rau cov kav dej.
5, xim zoo, tsis yog tsuas yog qhia tau xim ntuj xwb, tab sis kuj tuaj yeem tsim cov xim zoo nkauj thiab zoo nkauj, cov khoom zoo nkauj.
EVA thiab PVC tuaj yeem ua rau cov khau hauv qab, ua piv txwv, kom pom qhov txawv ntawm cov hauv qab uas lawv tsim tawm.
1, EVA cov hauv qab yog lub teeb yuag, mos thiab xis nyob, tsis muaj tshuaj lom thiab cov khoom siv zoo rau ib puag ncig, tsis yooj yim hnav, tsis yooj yim ya raws thiab tsw, tab sis kuj muaj qhov cuam tshuam ntawm kev poob siab thiab cua sov, feem ntau siv los ua cov khoom siv hauv nruab nrab ntawm khau. Tab sis EVA nws tus kheej nplua dua, kev tsim cov khau yuav tsum tau ua kev kho mob tiv thaiv kev plam.
2, PVC hauv qab tsis plam zoo, qhov zoo ntawm khau kuj mos heev, tsis yooj yim kom tau hmoov av, tab sis kuj yooj yim los ntxuav. Nws pheej yig, yooj yim hloov pauv thiab muaj xim zoo, thiab tuaj yeem ua ntau yam xim.
Ntxiv rau, PHYLON kuj yog ib yam khoom siv nrov hauv cov khau hauv qab, nws yog ib qho ua npuas dej thib ob, qhov saum npoo yog dawb thiab ntsws, nws qhov tshwj xeeb tshaj plaws yog lub teeb, zoo elasticity, thiab kev ua tau zoo cushioning, yog li nws feem ntau siv los ua khau kis las. PHYLON muaj ntau qhov zoo, tab sis kuj muaj qhov tsis zoo uas nws tsis yooj yim rau degrade.
