Zvivakwa zvemuviri zvezvinhu zvePolymeric

August 18, 2024

ATERMplastic, anozivikanwawo seArmmosoft plastiki, rudzi rwepurasitiki polymer rwunopenya kana runanzwisisika pakudziya kwakanyanya uye kuomesa pakatonhora.

Maketeni ePolymer anosungwa pamwechete kuburikidza neyebatanidzwa masimba, ayo anoderedza sezvo tembiricha inowedzera, ichigadzira iyo viscous mvura. THERMOplastic inogona kuiswa mune ino mamiriro uye inowanzo kushandiswa kuti zvigadzire zvekugadzira uchishandisa maitiro ekugadzirisa, kumanikidza kuumba, kuchinjika, uye kukwikwidza.

Zvivakwa zvemuviri zvePolymer

Chimiro, rudzi rwemunhu monomer runosvitswa polymers, uye zvimwe zvinhu zvese zvinokanganisa hunhu hwemurima. Izvi zvinotevera ndezvimwe zvezvivakwa zvemuviri uye zvemakemikari zvevanhu vePolymers:

Simba reChinese - Simba rePolymer's Simba rinogona kutambanudza pasina kutyora. Ichi chimiro chePolymers chinosarudza simba ravo remuviri uye kusimba.

Kunyungudutsa uye mapoinzi ekubikisa - Polymers ane yakanyanya kunyungudika uye ekubira mapoinzi. Maketani akareba anoreva masimba akasimba emisangano, uye nokudaro akanyungudika uye anovira.

Kuomesa - zvakaoma polymers vanopesana nezvinhu zvakaoma kuzvipinda. Ivo vanoshandirwa mukuvakwa kwemagetsi uye vanogona kushivirira kupfeka uye kubvarura pamwe nekukanda.

Density-yakavakirwa pamisiyano yakasarudzika, polymers inokatyamadzwa seyakanyanya-dens polymers kana yakaderera-density polymers.

Kupisa simba / kupisa undervity - Izvi zvinosarudza kuti inoshanda sei polymer yakafanana neyekupisa insulator. Iyo polymer kupisa kwehukama kunotsanangurwa nekugadzikana kwemamorekuru ayo.

Kuwedzera kwekuwedzera - Ichi chivakwa cherechedza kuti yakawanda sei polymer inowedzera kana inodonha kana ichinge yaratidzwa kupisa kana kutonhora.

Crystallinity - nekuti polymers ine zvishoma crystallinity ndeye brittle, ivo vanobatsira. Rudzi rwesangano remaketani ePolymeric runoratidza chimiro ichi.

Elasticity- polymers ine isina kusimba intermolecular zvinongedzo zvinotambanudza zvakanyanya uye zvine hunyanzvi.

Physical Properties of Polymeric Materials

1. Gasi PreMiability

Kubvumidzwa kwegesi kunowanzo kuratidzwa maererano nemhepo yekufungidzira kana kuenderana kwekufungidzira.

1) kufungidzira kwegesi

Zvinoreva huwandu hwegasi hunoparara kuburikidza ne1M2 nharaunda yefirimu yepurasitiki yeimwe gobvu pasi pe 0.1mpa mweya wekumanikidza (pasi pemamiriro ezvinhu) mukati memaawa makumi maviri nemana, m3.

2) Kufungidzira kuenderana

Pasi pemamiriro ezvinhu akaenzana, huwandu hwegasi hunoparara kuburikidza nefirimu yepurasitiki yeyunivhesiti nzvimbo uye yunivhesiti mune yuniti nguva uye pasi peyuniti Pressure Musical mutsauko.

Kwayedza Standard: GB / T 1038-2022 Firimu repurasitiki uye sheet Gasi Permeability bvunzo nzira (kusiyanisa nzira yekumanikidza)

2. Kunyungudza kwekunyorovesa

Mvura yemvura permeabilation inoratidzwa nehuwandu kana coefficient yemvura yemvura yekufungidzira.

1) Mvura Mvura Kufungidzirwa

Huwandu hwemvura yemvura inopfuura nepakati peiyo 1M2 yefirimu mukati me 24h pasi pemusiyano muVapor kumanikidzwa pakati pemativi maviri efirimu reimwe gobvu.

2) kunyorovesa permeability coefficient

Huwandu hwemvura yemvura inopfuura nepakati peyunivhesiti uye unit chiyero chefirimu pasi peyuniti nguva uye unit musiyano mutsauko wekumanikidza.

Test Standard: GB / T 1037-2021 nzira yekuyedza yemvura yemvura yekufungidzira kwemafirimu epurasitiki uye mashizha (Cup nzira).

3. Mvura Kuparadza

Kuparara kwemvura

Bvunzo

4. Kubata kwemvura

Kubata kwemvura kunoreva huwandu hwemvura yakabatanidzwa nekunyudza fungidziro yehukuru hwakataurwa mumvura yakaomeswa pane imwe tembiricha yegumi nemana.

Kwayedza Standard: GB / T 1034-2008 Mvura Inodziya Test nzira yePurasitiki

5. Kuwedzera uye Harsional Density

1) density

Iyo misa pane yuniti vhoriyamu yezvinyorwa pane yakatsemuka tembiricha. Iyo unit ndeye kg / m3 kana g / cm3 kana g / ml.

2) Kuwedzeredza kwerudzi (densives density)

Iyo huwandu hwehuwandu hwehuwandu hwehuwandu hwechinhu kune huwandu hwechirevo chezita reiyo vhoriyamu yakaenzana pakudziya kumwechete. Iyo dentives density pakupisa t ~ inotaurwa seDTT. Kana chirevo chacho chicherwa, chinonzi hukama hwehukama.

Density pa tembiricha t uye hukama hwehukama inogona kushandurwa neiyo inotevera formula:

Density and relative density at temperature t

Kupi sT ndeye kuwanda kweiyo fungidziro pakupisa t ℃; pt ndiyo density yefungidziro pakupisa t ℃; PW ndiyo density yemvura pakupisa t ℃.

Bvunzo

6. Shrinkage

MOLD shrinkage (MOLD shrinkage) inowanzoratidzwa seyakafukidzwa shrinkage kana kuumbwa shrinkage.

1) kuumbwa shrinkage

Shure kwaifanira kuenzana kweiyo chikamu chakaumbwa chiri chidiki pane kukura kweiyo inoenderana cavity, kazhinji inoratidzwa muMM / mm.

2) kuumbwa shrinkage

Zvakare inozivikanwa seMetrological Shrinkage, iri muzana yeiyo chiyero chechikuru chehukuru kune iyo inoenderana mold yechikuru chihure, chinowanzoratidzwa mu%.

Test Standard:

GB / T 15585-1995 kutsunga kweiyo jekiseni kuumbwa shrinkage yeTermoplastics

GB / T 17037.4-2003 Kugadzirira kweTermoplastic jekiseni kuumbwa Chikamu chechina: kutsunga kuumbwa shrinkage

JG / T6542-1993 kutsunga kwekudzvinyirira kweiyo orgmasetting kuumbwa mapurasitiki.
