Mwisi nini ya polymrike yubukorikori, polyester ihagaze nkimwe mumiryango myinshi kandi ikoreshwa cyane. Ariko, ingingo rusange yo kwitiranya ivuka hamwe nijambo "kuzura" na "guhaga" polyester. Mugihe basangiye igice cyizina, imiterere yimiti, imiterere, nibikorwa byanyuma ni isi itandukanye.
Gusobanukirwa iri tandukaniro ntabwo ari amasomo gusa - ni ngombwa kubashakashatsi, abashushanya ibicuruzwa, ababikora, ninzobere mu gutanga amasoko guhitamo ibikoresho bikwiye kumurimo, kwemeza imikorere, kuramba, no gukoresha neza.
Aka gatabo gasobanutse kazerekana aya masomo abiri yingenzi ya polymer, aguhe ubumenyi bukenewe kugirango ufate icyemezo cyuzuye kumushinga wawe utaha.
Itandukaniro ryibanze: Byose mubikoresho bya shimi
Itandukaniro ryibanze riri mumigongo ya molekulari, cyane cyane mubwoko bwa karubone-karubone ihari.
Pol Polyester idahagije (UPR):Nibisanzwe kandi bizwi cyane "polyester" mubikorwa byo guhimba. Urunigi rwarwo rurimo imigozi ibiri (C = C). Izi nkunga ebyiri nizo ngingo "zidahagije", kandi zikora nkibishobora guhuza imbuga.UPRs mubisanzwe bigaragara neza, sirup-imeze nkibisukari bitemba ubushyuhe bwicyumba.
Pol Polyester yuzuye (SP):Nkuko izina ribivuga, iyi polymer ifite umugongo ugizwe rwose na bonds imwe (CC). Hano nta reaction zibiri ziboneka zihari. Poliester zuzuye zisanzwe ni umurongo, uburemere-buke bwa termoplastique bukomeye mubushyuhe bwicyumba.
Bitekerezeho gutya: Polyester idahagije ni urutonde rwamatafari ya Lego afunguye ingingo zifunguye (imigozi ibiri), yiteguye gufungwa hamwe nandi matafari (umukozi uhuza). Polyester yuzuye ni amatafari yamaze gufatanyirizwa hamwe mumurongo muremure, ukomeye, kandi uhamye.
Kwibira cyane: Polyester idahagije (UPR)
Polyester idahagije (UPRs) ni polimosetting polymers. Bakenera imiti yimiti kugirango ikire ivuye mumazi ikomera, ikomeye.
Ubuhanga bwa chimie no gukiza:
UPRresinByaremwe mugukora diol (urugero, propylene glycol) hamwe nuruvange rwa aside ya dibasike yuzuye (urugero, Anhydride ya Phthalic na Anhydride ya Maleic). Anhydride ya Maleic itanga ingirakamaro zingirakamaro.
Amarozi abaho mugihe cyo gukira. UwitekaUPRresinivanze na monomer ikora, cyane cyane Styrene. Iyo catalizator (peroxide organic nkaMEKP) yongeyeho, itangiza ubuntu-radical polymerisation reaction. Molekile ya styrene ihuza-iherekejweUPRingoyi zinyuze mumirongo ibiri, kurema umuyoboro wuzuye, -ibice bitatu. Iyi nzira ntisubirwaho.
Ibyingenzi byingenzi:
Imbaraga zidasanzwe za mashini:Iyo ikize, irakomeye kandi irakomeye.
Kurwanya Ubushyuhe Bwinshi nubushyuhe:Kurwanya cyane amazi, acide, alkalis, hamwe numuti.
Ingero zingana:Kugabanuka gake mugihe cyo gukira, cyane cyane iyo bishimangiwe.
Kuborohereza gutunganya:Irashobora gukoreshwa muburyo butandukanye bwubuhanga nko kurambika amaboko, gutera hejuru, guhinduranya imashini (RTM), na pultrusion.
Ikiguzi-Cyiza:Mubisanzwe bihenze kurutaepoxyresinnibindi bikorwa-byo hejuru cyane.
Porogaramu y'ibanze:
UPRsni akazi kafiberglass ya plastiki ikomezwa (FRP) inganda.
Marine:Ubwato n'ubwato.
Ubwikorezi:Imodoka yimodoka, imurikagurisha ryamakamyo.
Ubwubatsi:Kubaka imbaho, impapuro zo hejuru, ibikoresho by'isuku (ubwogero, kwiyuhagira).
Imiyoboro & Tanks:Ku bimera bitunganya imiti n’amazi.
Ibuye ryakozwe:Ubuso bukomeye kuri konti.
Kwibira cyane: Polyester Yuzuye (SP)
Abapolisi Buzuyeni umuryango wa polimoplastike. Birashobora gushongeshwa nubushyuhe, bigahinduka, kandi bigakomera nyuma yo gukonja, inzira isubira inyuma.
Chimie nuburyo:
Ubwoko Bwinshi bwapolyester yuzuyeni PET (Polyethylene Terephthalate) na PBT (Polybutylene Terephthalate). Byakozwe nuburyo bwa diol hamwe na diacide yuzuye (urugero, Acide Terephthalic Acide cyangwa Dimethyl Terephthalate). Urunigi ruvuyemo ntirufite urubuga rwo guhuza, rukagira umurongo, polymer woroshye.
Ibyingenzi byingenzi:
Gukomera cyane no Kurwanya Ingaruka: Kuramba bihebuje no kurwanya gucika.
Kurwanya Imiti Nziza:Kurwanya imiti myinshi yimiti, nubwo itari rusange nkukoUPRs.
Ubushuhe:Irashobora guterwa inshinge, gusohora, hamwe na thermoformed.
Ibyiza bya Barrière Nziza:PET izwi cyane kubera imyuka ya gaze nubushuhe.
Kwambara neza no Kurwanya Kurwanya:Ikora ibereye kwimuka.
Porogaramu y'ibanze:
Poliester yuzuyeni hose muri plastiki yubuhanga no gupakira.
Gupakira:PET ni ibikoresho byibanze byamazi ya plastike nuducupa twa soda, ibikoresho byokurya, hamwe nudupapuro twa bliste.
Imyenda:PET ni "polyester" izwi cyane ikoreshwa mu myambaro, itapi, n'umugozi w'ipine.
Amashanyarazi ya plastike:PBT na PET bikoreshwa mubice byimodoka (gare, sensor, umuhuza), ibice byamashanyarazi (umuhuza, switch), nibikoresho byabaguzi.

Nigute wahitamo: Ninde ukwiye kumushinga wawe?
Guhitamo hagatiUPRna SP ni gake cyane iyo umaze gusobanura ibyo usabwa. Ibaze ibi bibazo:
Hitamo Polyester idahagije (UPR) niba:
Ukeneye igice kinini, gikomeye, kandi gikomeye kizakorerwa mubushyuhe bwicyumba (nkubwato bwubwato).
Kurwanya imiti isumba iyindi ni ikintu cyambere (urugero, kubigega byo kubika imiti).
Urimo gukoresha tekinoroji yo gukora igizwe no kurambika amaboko cyangwa pultrusion.
Igiciro nikintu gikomeye cyo gutwara.
Hitamo Polyester Yuzuye (SP - PET, PBT) niba:

Umwanzuro: Imiryango ibiri, Izina rimwe
Mugihe "yuzuye" na "idahagije" polyester yumvikana, igereranya amashami abiri atandukanye yumuryango wa polymer hamwe ninzira zitandukanye.Polyester idahagije Resinni nyampinga wa thermosetting yingufu-nyinshi, irwanya ruswa. Polyester yuzuye ni ifarashi ya thermoplastique ikora inyuma ya plastiki n’imyenda ikunze kugaragara ku isi.
Mugusobanukirwa itandukaniro ryibanze ryimiti, urashobora kurenga urujijo kandi ugakoresha ibyiza byihariye bya buri kintu. Ubu bumenyi buguha imbaraga zo kwerekana polymer ibereye, biganisha ku bicuruzwa byiza, inzira nziza, kandi amaherezo, intsinzi nini ku isoko.
