Iipropathi zomzimba zezinto ze-polymeric

August 18, 2024

I-thermoplastic, ekwabizwa ngokuba yi-Thermorensic yeplastiki, luhlobo lweposti yeplastiki ebalekayo okanye inqabile kubushushu obuphezulu kwaye i-Horens xa ipholile.

Imixokelelwane yePolymer idityaniswe kunye nemikhosi ye-intermolecular, enciphisa njengoko iqondo lobushushu liyanda, livelisa ulwelo lwe-viscous. I-Thertoverications inokuphinda iphinde yaphindaphindeke kule meko kwaye isetyenziswa ngokuqhelekileyo ukwenza iinxalenye ze-Polymer Ukulungisa iindlela zokulungisa i-polymer efana nenaliti, ukubumba, kunye nokuphuma.

Iipropathi zomzimba ze-polymer

Isakhiwo, uhlobo lweeyunithi ze-monomer apho ziveliswa khona, kunye nezinye izinto zonke zichaphazela iimpawu zepolymer. Oku kulandelayo zezinye zeepropathi zomzimba kunye neekhemikhali ze-polymers:

Amandla angamanqindi-amandla e-polymer ye-polymer kukukwazi kwayo kolula ngaphandle kokophula. Eli nqaku le-polymers libonisa amandla abo omzimba kunye nokuqina.

Amanqaku anyibilikisayo kunye ne-polymers anezinyibilikisi eziphezulu kakhulu kunye namanqaku abilayo. Imixokelelwane emide ichaza imikhosi engaqhelekanga ye-plungene, kwaye ke inyibilike kwaye inyibilike kwaye ibilise amanqaku.

Ubunzima-ii-polymers ezinzima ziyamelana nezinto ezinzima zingena. Baqeshwe ekwakhiweni kwee-elektroniki kwaye banokukunyamezela impahla kunye nokukrazula kunye nokukrakra.

Ukuxinana-ngokusekwe kuthelwaya ngoxinaniso, i-polymers icwangciswe njengama-thelymers ephezulu okanye i-polymers ephantsi.

Umthamo wobushushu / ukuphuphuma kobushushu - oku kumisela ukuba isebenza njani i-polymer ingumrhumo oshushu. Ukuqhutywa kobushushu bukaPolymer kugqitywa kukuqina kweemolekyuli zayo.

Ukwandiswa kwe-shirm - le mpahla imisela ukuba ingakanani i-polymer eyandayo okanye incipha xa ityhilwe kubushushu okanye ukubanda.

I-Crystallied - Kungenxa yokuba i-polymers ene-crystallies encinci ye-brittle, iluncedo ngakumbi. Uhlobo lombutho ohlanganisiweyo lweepolymeric quins lubonisa eli nqaku.

I-elastiky- polylimers enonxibelelwano olunobuthathaka be-insurmolar ngakumbi kwaye lingaphezulu kakhulu.

Physical Properties of Polymeric Materials

1. Isondo

Ubungqingqwa begesi buhlala bubonakaliswa ngokwemigaqo yomoya okanye ukulandelwa kwendlela yokufihla.

I-1) ukuguquka kwegesi

Ibhekisa kumthamo wegesi ejijekileyo nge-1m2 yendawo yefilimu yeplastiki yobungakanani be-0.1MPA uxinzelelo lomoya (phantsi kwemeko emiselweyo) kwiiyure ezingama-24, m3.

I-2) i-action caonded

Phantsi kwemeko esemgangathweni, ivolumu yegesi ebunjiweyo kwifilimu yeplastiki yendawo yeyunithi kunye nobubanzi beyunithi ngexesha leyunithi kunye ne-United Unist Press Press.

Umgangatho wovavanyo: GB / T 1038-2022 Ifilimu yefilimu kunye ne-Sheet Iphepha loVavanyo lweeNdawo zeRhafu (indlela eyahlukileyo yoxinzelelo)

2. Ukufuma komswakama

I-vapoer ye-vapor ye-vapor ibonakaliswa yimali okanye i-coudeoness ye-vapor ye-vapor.

1) I-vapor ye-vapor yamanzi

Ubunzima be-vapor yamanzi edlula kwi-1m2 yefilimu ngaphakathi kwe-24h ngaphantsi komehluko kwi-vapor yoxinzelelo phakathi kwala macala omfanekiso oqingqiweyo.

I-2) i-romation yokungasebenzi

Isixa-mali somphunga wamanzi esigqitha kwindawo yeyunithi kunye neyunithi ubukhulu befilimu phantsi kwexesha leyunithi kunye nomahluko woxinzelelo lweyunithi.

UMGAQO-NKQUBO WOKUVAVANYA: GB / T 1037-2021 Indlela yovavanyo ye-Vapor yamanzi yeFlample yeFlinemu kunye neShekhi (indlela yeNdebe ye).

3. Ukuqaqanjelwa kwamanzi

Amanzi aguqukayo (ukungangqinelani kwamanzi) kugqitywe ngokubeka isampulu yovavanyo phantsi koxinzelelo oluthile lwamanzi kunye nexesha elithile, kunye nokujonga inqanaba lokufana kwamanzi kwiliso lovavanyo ngokuthe ngqo.

Umgangatho wovavanyo: HG / T 2582-2022 Ukuzimisela kwamanzi e-radical yerabha okanye iplastiki yeplastiki.

4. Ukuthathwa kwamanzi

Ukufunxa kwamanzi kubhekisa kwinani lamanzi angena ngokuntywila imvume yesayizi echaziweyo kwiqondo lokuxinana kwi-24h.

UMGAQO-NKQUBO WOKUVAVANYA: GB / T 1034-2008 Indlela yoVavanyo lovavanyo lwamanzi lwePlastikis

5. Ukuxinana kunye nokuxinana kwesihlobo

1) Ukuxinana

Ubunzima bomthamo weyunithi nganye yezinto ezinobushushu ezichaziweyo. Iyunithi yi-kg / m3 okanye g / cm3 okanye g / ml.

2) Ukuxinana kwesihlobo (ukuxinana kwesihlobo)

Umyinge wobunzima bomthamo othile wento ukuya kubunzima bendawo yesalathiso kwiqondo elinye kwiqondo lobushushu. Ukuxinana kwesihlobo kwiqondo lobushushu t ~ livezwe njenge-DTT. Xa isixhobo sesalathiso ngamanzi, ibizwa ngokuba kukuxinana ngokuhambelana.

Ukuxinana kubushushu T kunye nokuxinana kwesihlobo kunokuguqulwa ngale ndlela ilandelayo:

Density and relative density at temperature t

Apho st yi-st sisihlobo sophawu lobushushu t ℃; I-pt kukuxinana kwesati seqondo lobushushu t ℃; I-PW kukuxinana kwamanzi ngamaqondo obushushu T ℃.

6. i-shrinkage

Ukuntywila i-Shrinkge (i-shrinkge) ihlala ibonakaliswa njengokutsala i-shrinkge okanye i-spelling shrinkage.

I-1) i-spelling shrinkage

Indlela ubungakanani benxalenye yenxalenye ebunjiweyo incinci kunesayizi ye-cavity efanelekileyo, ihlala ibonakaliswa kwi-mm / mm.

2) ukubumba i-shrinkage

Kwakhona eyaziwa njenge-shorigicage, yipesenti yomlinganiselo wobukhulu obuhambelana nobungakanani obuhambelana nobungakanani obuhambelana noko, kubonakaliswa kwi%.

Umgangatho wovavanyo:

I-GB / T 15585-1995 Ukuzimisela kwenaliti yejeying yejeyithi ye-thermoplastics

I-GB / T 17037.4-2003 Ukulungiswa kwenaliti ye-thermoplastic yejele ye-4: Ukumiselwa kweSpenging Shrinkage
