Cia kuv qhia rau koj.
PVC:
Qhov zoo: Cov kua qaub thiab alkali tsis kam, hluav taws xob rwb thaiv tsev, hluav taws kub tsis kam, kev tua tus kheej (cov khoom siv hauv tsev), hnav-tiv taus, suab nrov thiab kev poob siab.
Hard pvc nto hardness siab tensile zog (siab dua PE, siv lead ua ABS) tuaj yeem siv los ua cov khoom siv engineering
Mos pvc yog mos, elastic thiab resistant rau folding
Disadvantages: tsis resistant rau organic solvents, rhiab heev rau thaum tshav kub kub ua, tsis zoo thermal stability, yooj yim degrade thaum rhuab
Hard PVC, tsis kub yuav ua nkig;Mos PVC, yuav harden ntawm qhov kub thiab txias.Hard PVC yog rhiab heev rau strain thiab tsis yooj yim rau rov qab los tom qab deformation.Mos pvc ua cov txheej txheem yuav decompose me me ntawm HCL, yooj yim ua rau cov khoom siv corrosion

PS:
Qhov zoo: acid thiab alkali tsis kam thiab tsis tshua muaj zog cawv hluav taws xob rwb thaiv tsev zoo pob tshab, siab gloss, yooj yim luam tawm, dawb xim, tsis muaj ntxhiab tsw, kub tsis kam thiab kev laus ua haujlwm.
Disadvantages: nyuaj thiab brittle nto hardness yog tsawg yooj yim rau khawb tsis kam mus rau feem ntau cov organic solvents.

PP:
Qhov zoo: tiv thaiv kom tsis txhob qaug zog, tiv thaiv cov dej kub npau npau (cov cuab yeej kho mob, cov khoom siv rooj tog) muaj zog cov khoom siv hauv chav sov> pe> abs> ps, cov khoom siv hluav taws xob kub kub yuav tsis txo qis ntau, cov khoom siv hluav taws xob tsis zoo yog qhov tsis zoo. nyuaj, nkig nrog zoo heev nto luster (lub tsev khoom siv plhaub)
Disadvantages: tsis txaus rigidity ntawm qhov kub thiab txias, nkig ntawm qhov kub thiab txias;Ib puag ncig tsis zoo, tsis haum rau sab nraum zoov siv tensile lub zog anisotropy, cov khoom yooj yim rau deformation luam ntawv kev ua haujlwm tsis zoo rau lub sijhawm ntev.

ABS:
Qhov zoo: zoo gloss zoo hard tenacity rigid mechanical zog me ntsis yooj yim luam ntawv tsis tshua muaj kub cuam tshuam kev ua tau zoo zoo me me stability thiab dej tsis kam
Disadvantages: tsis zoo huab cua tsis kam rau cov kuab tshuaj organic (yooj yim tawg)

PMMA:
Qhov zoo: Cov khoom siv kho qhov muag, tuaj yeem dhau los ntawm lwm cov ntaub ntawv pob tshab tsis tuaj yeem dhau los ntawm lub teeb, lub teeb tuaj yeem ua rau sab hauv, tuaj yeem siv ua fiber ntau tiv thaiv.
Disadvantages: Tsawg nto hardness thiab khawb kuj
FRP: Kuj hu ua GRP, iav hlau
Lub teeb yuag, siab tensile lub zog (txawm tias ntau dua li cov hlau bar) zoo corrosion kuj rau txhua yam ntawm cov kuab tshuaj zoo hluav taws xob kev ua tau zoo, zoo rwb thaiv tsev, zoo thermal kev ua tau zoo, tsis tshua muaj thermal conductivity, kub kuj thiab zoo tsim.
Disadvantages: tsis txaus rigidity, tsis zoo rau lub sij hawm ntev kub tsis kam, tsis tshua muaj shear degree ntawm aging txheej nyob rau hauv hnyav ib puag ncig.
 
PET:
Qhov zoo: Cov khoom siv kho tshuab zoo, cuam tshuam lub zog yog 3 ~ 5 npaug ntawm lwm cov yeeb yaj kiab, zoo folding kuj
Resistance rau feem ntau cov kuab tshuaj
Lub tshav kub tsis kam ntawm PET ntshiab tsis siab, thiab thermal deformation kub tsuas yog li 85 ℃, tab sis.Lub thermal deformation kub ntawm iav fiber reinforced PET tuaj yeem ncav cuag 225 ℃
PET muaj qhov zoo tiv thaiv kev laus
PET tsis hlawv yooj yim
Impermeability, zoo heev tiv taus roj, dej, roj thiab tsw.
High transparency, tuaj yeem thaiv UV, zoo luster.
Tsis muaj tshuaj lom, tsis qab, noj qab haus huv thiab kev nyab xeeb, tuaj yeem siv ncaj qha rau kev ntim khoom noj.
Zoo creep kuj, qaug zog kuj, kev sib txhuam kuj thiab seem stability, me me hnav thiab siab hardness, zoo rwb thaiv tsev
Disadvantages: tsis zoo corona kuj
Lub molding shrinkage tus nqi yog loj, qhov seem stability yog pluag, lub crystallization molding yog nkig, lub tshav kub kuj yog tsawg.
Kev tiv thaiv tsis muaj zog acids thiab cov kuab tshuaj organic, tab sis tsis kub resistant rau dej immersion, alkali tsis kam.

HDPE:
Qhov zoo: acid thiab alkali tsis kam mus rau cov organic hnyav taw tes rwb thaiv tsev zoo kub tsis tshua muaj peev xwm tswj tau qee qhov toughness
Nto hardness tensile lub zog muaj zog dua LDPE
Disadvantages: cov khoom siv tsis zoo, tsis zoo permeability, yooj yim deformation, yooj yim laus, yooj yim kev ntxhov siab tawg
Brittle, scratchy thiab nyuaj rau luam
 
LDPE:
Qhov zoo: kua qaub thiab alkali tsis kam rau cov kuab tshuaj organic zoo hluav taws xob rwb thaiv tsev ntawm qhov kub thiab txias tuaj yeem tswj tau qee qhov toughness
