Na Andy wo mu ruganda rwa Baiyear
Yavuguruwe ku ya 2 Ugushyingo 2022
Hano hari amakuru yamakuru yinganda za Baiyear.Ibikurikira, Baiyear izagabanya uburyo bwo guterwa inshinge mu ngingo nyinshi kugirango tumenye isesengura ryibikoresho fatizo byo guterwa inshinge, kuko hari byinshi birimo.Ibikurikira ni ingingo ya gatandatu.
(14).PPO (polifhenylene ether)
1. Imikorere ya PPO
Okiside ya polifenilene ni poly-2,6-dimethyl-1,4-fenylene oxyde, izwi kandi nka polyphenylene oxyde, izina ry'icyongereza Polyphenyleneoxiole (bita PPO), polifhenelene yahinduwe ihindurwa na polystirene cyangwa izindi polymers.Imibonano mpuzabitsina polifhenylene ether, yitwa MPPO.
PPO (NORLY) ni plastiki yubuhanga ifite ibintu byiza byuzuye.Ifite ubukana burenze PA, POM na PC, imbaraga za mashini nyinshi, gukomera gukomeye, kurwanya ubushyuhe bwiza (ubushyuhe bwo guhindura ubushyuhe ni 126 ℃), hamwe no guhagarara neza (ubushyuhe bwo kugabanuka).igipimo cya 0,6%), kwinjiza amazi make (munsi ya 0.1%).Ingaruka ni uko idahagaze neza ku mirasire ya ultraviolet, igiciro ni kinini, kandi dosiye ni nto.
PPO ntabwo ari uburozi, ibonerana, ifite ubucucike buke ugereranije, kandi ifite imbaraga zidasanzwe zubukanishi, kurwanya imihangayiko, kurwanya imirwanyasuri, kurwanya ubushyuhe, kurwanya amazi, no kurwanya imyuka y'amazi.Ibikoresho byiza byamashanyarazi muburyo butandukanye bwubushyuhe no guhindagurika inshuro nyinshi, nta hydrolysis, kugabanuka gakeya kugabanuka, flame retardant no kuzimya, kutarwanya aside irike, alkalis, hydrocarbone ya aromatic, hydrocarbone ya halogene, amavuta, nibindi, byoroshye kubyimba Cyangwa gucika intege, ibibi byingenzi ni ukutagira amazi meza, gutunganya bigoye no kuyashiraho, ibyinshi mubikorwa bifatika ni MPPO (imvange ya PPO cyangwa ibivangwa), nka PS guhindura PPO, birashobora kunoza cyane imikorere yo gutunganya, kunoza imihangayiko yo guhangana ningaruka Kurwanya Imikorere, kugabanya ibiciro, kugabanuka gake mukurwanya ubushyuhe hamwe nuburabyo.
Polimeri zahinduwe zirimo PS (harimo HIPS), PA, PTFE, PBT, PPS na elastomers zitandukanye, polysiloxane, PS yahinduye paraffin ya PPO, ibicuruzwa binini, MPPO nuburyo bukoreshwa mubwubatsi rusange bwa plastike.Ubwoko bunini bwa MPPO ni PPO / PS, PPO / PA / elastomers na PPO / PBT elastomer.
2. Ibiranga inzira ya PPO:
PPO ifite ibishishwa byinshi bishonga, amazi mabi, hamwe nuburyo bwo gutunganya neza.Mbere yo kuyitunganya, igomba gukama ku bushyuhe bwa 100-120 ° C mu masaha 1-2, ubushyuhe bwo kubumba ni 270-320 ° C, kandi ubushyuhe bwibumba bugenzurwa neza kuri 75-95 ° C.gutunganya.Mubikorwa byo gukora iyi plastiki yinzoga ya pulasitike, uburyo bwo gutemba bwindege (inzoka ya serpentine) biroroshye kubyazwa umusaruro imbere ya nozzle, kandi umuyoboro utemba wa nozzle nibyiza cyane.
Umubyimba ntarengwa uri hagati ya 0.060 na 0,125 kuri santimetero zisanzwe na 0.125 kugeza 0.250 kuri santimetero zubatswe, kandi gutwika kuva kuri UL94 HB kugeza kuri VO.
3.Uburyo busanzwe bwo gusaba:
PPO na MPPO birashobora gutunganywa muburyo butandukanye bwo gutunganya nko guterwa inshinge, gusohora, guhumeka, kubumba, kubira ifuro no gukwirakwiza amashanyarazi, gutwikira vacuum, gutunganya imashini zandika, nibindi, kubera ubukonje bwinshi bwo gushonga hamwe nubushyuhe bwo gutunganya cyane.
PPO na MPPO bikoreshwa cyane cyane mubikoresho bya elegitoroniki, imodoka, ibikoresho byo murugo, ibikoresho byo mu biro hamwe n’imashini zinganda, nibindi, ukoresheje MPPO mukurwanya ubushyuhe, kurwanya ingaruka, guhagarara neza, kurwanya ibishishwa, no kurwanya ibishishwa;
Irangi hamwe namashanyarazi: bikoreshwa mugukora imbaho zimodoka, gride ya radiator, grilles ya disikuru, kanseri, agasanduku ka fuse, agasanduku ka relay, umuhuza, ibipfukisho byiziga;ikoreshwa cyane munganda zamashanyarazi na elegitoronike mugukora imiyoboro, coil winding Spools, guhinduranya ibyuma, ibikoresho byo guhuza ibikoresho, kwerekana ibikoresho bya elegitoronike, imashini zihindura ibintu, ibikoresho bya batiri, mikoro nibindi bice.
Ibikoresho byo murugo bikoreshwa kuri tereviziyo, kamera, kaseti za videwo, ibyuma bifata amajwi, ibyuma bifata ibyuma bikonjesha, ubushyuhe, abateka umuceri nibindi bice.Irashobora gukoreshwa nkibice byo hanze nibigize kopi, sisitemu ya mudasobwa, printer, imashini za fax, nibindi. Byongeye kandi, irashobora gukoreshwa nka kamera, ingengabihe, pompe yamazi, igikonoshwa nibice, ibikoresho byicecekeye, umuyoboro, umubiri wa valve, ibikoresho byo kubaga, sterilizer nibindi bikoresho byubuvuzi.
Impanuka nini nini irashobora gukoreshwa mubice binini byimodoka nka konona, bumpers, hamwe no kubumba ifuro rito.Irakwiriye kubyara ibicuruzwa binini bifite ubukana buhanitse, butajegajega buringaniye, uburyo bwiza bwo kwinjiza amajwi, hamwe nuburyo bugoye bwimbere, nkibikonoshwa bitandukanye byimashini, ibishingwe, imbere Imbere hamwe nigishushanyo gifite umudendezo mwinshi, kandi ibicuruzwa biroroshye.
(15).PBT polybutylene terephthalate
1. Imikorere ya PBT:
PBT nimwe mubintu bikomeye bya injeniyeri ya thermoplastique.Nibikoresho bya kimwe cya kabiri kristaline ifite imiterere ihamye yimiti, imbaraga za mashini, imiterere yumuriro wamashanyarazi hamwe nubushyuhe bwumuriro.Ibi bikoresho bifite umutekano muke mubidukikije byinshi, kandi PBT ifite intege nke za hygroscopique.Imbaraga zingana za PBT zidafite ingufu ni 50MPa, naho imbaraga zingana zubwoko bwikirahure PBT ni 170MPa.Ibyongeweho ibirahuri byinshi bizatera ibikoresho gucika.
PBT;kristallisation irihuta cyane, izatera guhindagurika bitewe no gukonja kutaringaniye.Kubikoresho bifite inyongeramusaruro yikirahure, kugabanuka mubyerekezo birashobora kugabanuka, ariko kugabanuka mubyerekezo perpendikulike kubikorwa ahanini ni nkibikoresho bisanzwe.
Igipimo rusange cyo kugabanuka kiri hagati ya 1.5% na 2.8%.Ibikoresho birimo 30% byongeweho ibirahure bigabanuka hagati ya 0.3% na 1,6%.Gushonga (225% ℃) hamwe nubushyuhe bwo hejuru bwubushyuhe buri munsi yibikoresho bya PET.Ubushyuhe bwa Vicat bugera kuri 170 ° C.Ubushyuhe bwikirahure (ikirahure trasitiotemperature) kiri hagati ya 22 ° C na 43 ° C.
Bitewe nigipimo kinini cyo korohereza PBT, ubukonje bwacyo buri hasi cyane, kandi igihe cyinzira yo gutunganya ibice bya plastiki muri rusange ni gito.
2. Ibiranga inzira ya PBT:
Kuma: Ibi bikoresho byoroshye hydrolyz mubushyuhe bwinshi, bityo gukama mbere yo gutunganya ni ngombwa.Gusabwa gukama mu kirere ni 120C mu masaha 6 ~ 8, cyangwa 150C mu masaha 2 ~ 4.
Ubushuhe bugomba kuba munsi ya 0,03%.Niba byumye hamwe na desiccator ya hygroscopique, ibisabwa ni 150 ° C mumasaha 2.5.Ubushyuhe bwo gutunganya ni 225 ~ 275 ℃, naho ubushyuhe busabwa ni 250 ℃.Kubikoresho bidashyizwemo ingufu, ubushyuhe bwububiko ni 40 ~ 60 ℃.Umuyoboro ukonjesha wububiko ugomba kuba wateguwe neza kugirango ugabanye igice cya plastike.Gukwirakwiza ubushyuhe bigomba kwihuta ndetse ndetse.
Diameter isabwa kumuyoboro ukonjesha ni 12mm.Umuvuduko wo gutera inshinge uringaniye (kugeza 1500bar), kandi umuvuduko wo gutera inshinge ugomba kwihuta bishoboka (kuko PBT ikomera vuba).Kwiruka n irembo: Birasabwa gukoresha uruziga ruzenguruka kugirango wongere umuvuduko wumuvuduko (formulaire yuburambe: kwiruka diameter = uburebure bwa plastike + 1.5mm).
Ubwoko butandukanye bwamarembo burashobora gukoreshwa.Abiruka bashyushye nabo barashobora gukoreshwa, ariko hagomba kwitonderwa kugirango wirinde kumeneka no kwangirika kwibikoresho.Irembo rya diameter rigomba kuba hagati ya 0.8 ~ 1.0 * t, aho t nubunini bwigice cya plastiki.Niba ari irembo ryarengewe, hasabwa byibuze diameter ya 0,75mm.
3.Uburyo busanzwe bwo gusaba:
ibikoresho byo murugo (ibyuma bitunganya ibiryo, ibikoresho bisukura vacuum, ibyuma bikoresha amashanyarazi, inzu yumisha umusatsi, ibikoresho bya kawa, nibindi), ibikoresho byamashanyarazi (guhinduranya, amazu ya moteri, agasanduku ka fuse, urufunguzo rwa mudasobwa, nibindi), Inganda zikoresha imodoka (radiator grilles, imibiri yumubiri, ibipfukisho, inzugi nidirishya, nibindi.
Ubumenyi bwinshi bwatangijwe muriki gice.Kubindi bumenyi, Baiyear azavugurura vuba bishoboka.Tuzahora tuvugurura ibikoresho fatizo bya pulasitike, gutunganya inshinge, gutunganya ibikoresho byo guterwa inshinge, gushushanya, gushushanya, gushushanya ibikoresho, kumenyekanisha ibyuma, amakuru yubumenyi kubyerekeranye no gukwirakwiza agasanduku, gukora agasanduku k'ibyuma, ibikoresho byo gutunganya ibyuma, gutangiza amazi. agasanduku gahuza, idirishya ridafite amazi, nibindi. Niba ushishikajwe nubumenyi bwavuzwe haruguru, urashobora kuntabaza igihe icyo aricyo cyose, nzishimira kugukorera kandi ntegereje ko uhagera.
