Amakuru y'Ikigo

1. Ubucucike / isano

Ubucucike bugereranije bivuga ingano ya sosiyete ikora imiti.

Umubare werekana ikigereranyo cyubwinshi bwikintu cyimiti nubucucike bwamazi.

2. Ubushyuhe bwo guhumeka hamwe na coefficient de compression

Ubushyuhe bwo guhumeka nubunini bufashwe na garama ya plastike (cm³ / g), nakwikuramoni igipimo cyijwi cyangwa ubushyuhe bwo guhumeka hagati yifu ya electrostatike nigice cya plastiki (agaciro kayo karenze 1). Byose birashobora gukoreshwa mugusobanura ingano yicyumba cyo gusohora firime. Agaciro kanini k'agaciro gasanzwe gateganya ko ingano y'icyumba gisohora igomba kuba nini. Muri icyo gihe, irerekana kandi ko ifu ya electrostatike ifite pompe nyinshi zo mu kirere, umuyoboro wa gazi uragoye, igihe cyo kubumba ni kirekire, kandi umusaruro ukaba muke. Ibinyuranye nukuri niba ubushyuhe bwo guhumeka ari buto, kandi nibyiza gukanda no kugabanya.

3.Kwinjiza amazi

Kwinjiza amazi bivuga urwego rwo gusya kwa plastike no kwinjiza amazi. Uburyo bwo gupima ni ukubanza gukama icyitegererezo no kugipima. Nyuma yo gushira mumazi muminsi 24 cyangwa ibiri, uyikureho kandi wongere upime, hanyuma ubare ijanisha ryongewe kumafaranga, aribwo kwinjiza amazi. igitsina.

4. Igikorwa

Ubushobozi bwa plastike bwo kuzuza umwobo munsi yubushyuhe hamwe nigitutu cyakazi byitwa ibikorwa. Nibintu nyamukuru byingenzi byingenzi byikoranabuhanga bitunganyirizwa hamwe iyo kashe ipfuye. Igikorwa gishya cyoroshye gukora cyane kumurika, kuzuza umwobo ntabwo ari mwinshi, ibice bya pulasitike biragabanijwe neza, epoxy resin hamwe nuwuzuza byegeranijwe ukwabyo, byoroshye kwizirika kubibumbano, gusohora no kurangiza biragoye, gushira hasi ni kare cyane nibindi ibibi. Ariko, niba ibikorwa ari bito, kuzura ni bigufi, ntabwo byoroshye gukora, kandi igitutu cyo gukora ni kinini. Kubwibyo, ibikorwa byo gukoresha plastike bihuye namabwiriza agenga ibice bya plastiki, gukora inzira no gukora ibipimo.

5. Ibiranga ibintu bikomeye

Polyurethane elastomer ihindurwa muburyo bwimitsi ihindagurika mugihe cyo gushyuha no guhangayika mugihe cyose cyo gukora. Mugihe ibikorwa byagutse, cavit iruzuye, kandi mugihe kimwe, aldol yegeranye. Ubucucike bwambukiranya bukomeje kwiyongera, kandi ibikorwa biroroshye. Nimashini ikora yikora rwose igabanuka kandi ikuma buhoro buhoro ibikoresho byashonge. Iyo ushizeho kashe, umuvuduko wo kugabanuka gukomeye birihuta, kandi ibikoresho bifite ibikorwa bigufi byinsanganyamatsiko bigomba kwitonda kugirango byorohereze kugaburira, gupakira no gupakurura ibyinjijwe, no guhitamo ibipimo ngenderwaho bifatika nibikorwa bifatika kugirango wirinde gukomera hakiri kare cyangwa bikomeye kugabanuka Kubura, bivamo kubumba nabi ibice bya plastiki.

6.Ubushuhe hamwe n’ibinyabuzima bihindagurika

Ubwoko bwose bwa plastiki bufite urwego rutandukanye rwubushuhe hamwe n’ibinyabuzima bihindagurika. Iyo ari byinshi, ibikorwa biraguka, biroroshye kurengerwa, igihe cyo gutsimbarara ni kirekire, kigabanya kwaguka, kandi biroroshye kubyara imiterere yumuraba, kwaguka no kwikuramo nibindi bibi nibibi. Imashini yubukanishi namashanyarazi yibice bya plastiki. Ariko, mugihe plastiki yoroshye cyane, bizanatera ibikorwa bibi no gukora bigoye. Kubwibyo, plastiki zitandukanye zigomba gushyuha nkuko bisabwa. Nibyoroshye gushyushya ibikoresho hamwe no gufata amazi akomeye, cyane cyane mugihe cyizuba, kabone niyoibikoresho bishyushyebigomba kwirindwa. Kwinjira

7.Ubushyuhe bukabije

Ubushyuhe bukabije bwa plastike bivuga plastiki zimwe na zimwe zorohereza ubushyuhe. Iyo bahuye nubushyuhe mubushyuhe bwinshi, igihe ni kirekire cyangwa igice cyambukiranya ifunguro ni gito cyane. Iyo ingaruka nyazo zo gukata ari nini, kwiyongera kwubushyuhe bwububiko birashoboka gutera ibara, depolymerisation, no gutandukana. Plastike ifite ubu bwoko bwibiranga bita plastiki-yubushyuhe.

8. Amazi meza

Amashanyarazi amwe (nka polyakarubone) niyo afite amazi make, ariko azagabanywa munsi yubushyuhe bwinshi numuvuduko mwinshi. Ubu bwoko bwimikorere bwitwa sensibilité yamazi, kandi biroroshye kubishyushya mbere.

9.Kwinjiza amazi

Plastike yakekaga ko kubera ko hari inyongeramusaruro zinyuranye zituma bagira urwego rutandukanye rwo guhuza amazi, plastiki irashobora kugabanywa mubice bibiri: kwinjiza amazi, gufata neza, hamwe no kutagira hygroscopique kandi bigoye kubahiriza amazi. Bikekwa ko ibivumbikisho bigenzurwa murwego rwemewe, bitabaye ibyo ubuhehere bugahinduka imyuka munsi yubushyuhe bwinshi n’umuvuduko mwinshi cyangwa ingaruka nyazo ziterwa na hydrolysis zibaho, bizatera epoxy resin kubyimba, kugabanya ibikorwa byayo, no kubura isura nibikorwa bya mashini na mashanyarazi. byiza. Kubwibyo, plastiki ikurura amazi ashyutswe nuburyo bukwiye bwo gushyushya nubuziranenge nkuko bisabwa, kandi induction itaziguye ikoreshwa kugirango hirindwe kongera gutwarwa nubushuhe mugihe cyo kubukoresha.

10.Guhumeka

Guhumeka bivuga imikorere yo kohereza imyuka ya firime ya plastike cyangwa ikibaho cya plastiki

11.Gushonga indangagaciro

Icyerekezo cya Melt (MI) nigiciro gisanzwe cyerekana ibikorwa byibikoresho bya pulasitike mugihe cyo gukora no gutunganya.

12.Imbaraga zingana / kurambura

Imbaraga zingutu bivuga ingano yingufu zisabwa kugirango urambure ibintu bya plastiki kurwego runaka (nkumusaruro utangwa cyangwa aho ucika). Mubisanzwe birangwa nubuso rusange bwa buri kigo. Kandi ijanisha ryuburebure nyuma yo gukurura uburebure kugeza muburebure bwumwimerere ni ugusenyuka.

13.Imbaraga zo kwikuramo imbaraga

Imbaraga zo kwikuramo ibibyimba nubushobozi bwa plastike bwo kurwanya ibibyimba.

14.Ingaruka zo gukomeretsa

Imbaraga zo guhonyora imbaraga zerekeza ku mbaraga za kinetic plastike ishobora kwihanganira iyo ihinduwe nimbaraga zo hanze.

15.Imbaraga

Imbaraga za plastiki rusange zisanzwe zirangwa nuburyo bubiri bwo kugenzura, ubukana bwa Rockwell nubukomere bwa Somo. Muri kiriya gihe, A ya Shao yakoreshwaga mu gupima plastiki yoroshye, nka TPE nizindi elastomeri ya polyurethane cyangwa reberi y’ibirunga, nibindi.; Shao's D yakoreshejwe mu gupima plastiki zikomeye, nka plastiki rusange-rusange rusange hamwe na plastiki yubuhanga, kandi ibyinshi mubikorwa byubwubatsi bukora cyane umushinga wa plastike cyangwa plastiki yubushakashatsi bukomeye bigomba gupimwa na Rockwell.

16.Shyushya ubushyuhe

Ubushyuhe bwo kugoreka ubushyuhe nubushyuhe igipimo cya plastiki gipima kugeza kurwego munsi yumuvuduko wakazi nubushyuhe.

17.Kurwanya ubushyuhe burebure

Kurwanya ubushyuhe burebure bwigihe kirekire bivuga kurwanya ubushyuhe bwibikoresho bya pulasitike mugukoresha igihe kirekire.

18.Imiterere-idashobora kwihanganira

Imiterere yibiyobyabwenge bidashobora kwangirika bivuga guhindura uburemere, ingano, imbaraga zingana no kurambura ibikoresho bya plastiki nyuma yo kwibizwa mumashanyarazi kama mubushyuhe mugihe runaka. Itandukaniro rito ry'irondakoko ryerekana ihinduka ryiza rya Dielectric.

19.Kurwanya gusaza

Kurwanya gusaza bivuga kurwanya ibikoresho bya pulasitike ku ngaruka z’izuba, ubushyuhe, umwuka, umuyaga n’imvura mu bidukikije byo hanze, bitera impinduka zikomeye no kwangirika.

20.Kugaragara

Ubusobanuro bwerekana kohereza urumuri rwa plastike mumucyo ugaragara. Plastike irashobora kugabanywa mu kohereza urumuri, gukorera mu mucyo no mu mucyo ukurikije urwego rw'urumuri runyura.

21.ubworoherane

Koroha bivuga urwego rwikirahure cyindorerwamo isa niy'ibintu bya shimi bishobora kugabanya urumuri. Koroha neza bivuga ubuso bwiza bwibintu bya shimi.

22.Igice cyo kubika cyangiza voltage ikora

Umuvuduko wakazi wokwirinda ibyangiritse ni voltage yumurimo wongerera itandukaniro ryinshi rishobora kugeragezwa kugirango ugere kurimbuka kwingufu za dielectric, ugabanijwe nagaciro (Kv / mm) intera iri hagati ya electrode zombi (ubunini bwa igice cy'ikizamini).

23.ubushyuhe bwo guhuza

Ubushyuhe bwo guhuza bwitwa kandi ubushyuhe bwo gushonga no guhumeka, akaba ari imbaraga za kinetic zikenerwa muguhimba cyangwa gushonga no korohereza kristu ya polymer. Iki gice cyingufu za kinetic gikoreshwa mugushonga kristaline yububiko bwa polymer. Kubwibyo, iyo polymer ya kristaline itunganijwe no guterwa inshinge, bisaba imbaraga za kinetic kugirango zigere ku bushyuhe bwihariye bwo gushonga kuruta iyo polymer amorphous itunganijwe no guterwa inshinge. Ntibikenewe ubushyuhe bwo gushonga no guhumeka.

24.ubushyuhe bwihariye

Ubushyuhe bwihariye nubunini bwubushyuhe bukenewe mugihe ubushyuhe bwibikoresho fatizo byikigo byiyongereyeho dogere 1 [J / kg.k].

25.gukwirakwiza ubushyuhe

Ubushuhe bwa Thermal diffusivite bivuga igipimo cyerekana ko ubushyuhe bwimurwa mubikoresho byo gushyushya. Yitwa kandi coefficient de transfert. Agaciro kayo nubunini bwubushyuhe (ubushyuhe bwihariye) hamwe nigogorwa ryibintu hamwe no kwinjizwa bisabwa mugihe ubushyuhe bwibikoresho fatizo byinganda byiyongereye kurwego rwa 1. Igipimo cy'ubushyuhe (coefficient de transfert) cyatoranijwe. Umuvuduko wakazi ntushobora kwangiza coefficente yumuriro, ariko ubushyuhe ni bubi cyane.
