PPO
Imikorere ya PPO
Polifhenylether ni poly2, 6-dimethyl-1, 4-fenylether, izwi kandi nka polyphenyloxy, Polyphenyleneoxiole (PPO), polifhenylether yahinduwe ihindurwa na polystirene cyangwa izindi polymers (MPPO).
PPO ni ubwoko bwa plastike yubuhanga ifite imikorere myiza yuzuye, ubukana burenze PA, POM, PC, imbaraga za mashini nyinshi, gukomera gukomeye, kurwanya ubushyuhe bwiza (ubushyuhe bwo guhindura ubushyuhe bwa 126 ℃), guhagarara neza (kugabanuka kwa 0,6%) , igipimo gito cyo kwinjiza amazi (munsi ya 0.1%).Ikibi nuko UV idahindagurika, igiciro ni kinini kandi amafaranga ni make.PPO ntabwo ari uburozi, bubonerana, ugereranije n'ubucucike buto, hamwe n'imbaraga zidasanzwe za mashini, kurwanya imihangayiko irwanya imbaraga, kurwanya imigezi, kurwanya ubushyuhe, kurwanya amazi, kurwanya imyuka y'amazi.
Mubushuhe butandukanye bwubushuhe, itandukaniro ryinshuro zingirakamaro zumuriro mwiza w'amashanyarazi, nta hydrolysis, gukora igipimo cyo kugabanuka ni gito, kirashya hamwe no kwaka umuriro, kurwanya aside ya organic organique, alkali, hydrocarbon ya hydrocarubone, amavuta ya hydrocarubone, amavuta nibindi bikorwa bibi, kubyimba byoroshye cyangwa guhagarika umutima, imbogamizi nyamukuru ni ugushonga nabi, gutunganya no gukora ingorane, ibyinshi mubikorwa bifatika kuri MPPO (PPO ivanze cyangwa ibivanze).
Ibiranga inzira ya PPO
PPO ifite ubukonje bwinshi bwo gushonga, kutagira amazi meza hamwe nuburyo bwiza bwo gutunganya.Mbere yo gutunganywa, ni ngombwa gukama amasaha 1-2 ku bushyuhe bwa 100-120 ℃, gukora ubushyuhe ni 270-320 ℃, kugenzura ubushyuhe bwubushyuhe bukwiye kuri 75-95 ℃, no gukora gutunganya ibintu bisabwa "hejuru ubushyuhe, umuvuduko mwinshi n'umuvuduko mwinshi ”.Mubikorwa byo gukora iyi nzoga ya pulasitike, uburyo bwo gutembera kwindege (uburyo bwinzoka) biroroshye kubyazwa umusaruro imbere ya nozzle, kandi umuyoboro wa nozzle ni mwiza.
Umubyimba ntarengwa uri hagati ya 0.060 na 0.125 kuri santimetero zisanzwe zakozwe na 0.125 kugeza 0.250 kuri santimetero zububiko.Umuriro uva kuri UL94 HB kugeza kuri VO.

PPO na MPPO bikoreshwa cyane cyane mubikoresho bya elegitoroniki, imodoka, ibikoresho byo murugo, ibikoresho byo mu biro hamwe n’imashini zinganda, nibindi, ukoresheje ubushyuhe bwa MPPO, kurwanya ingaruka, guhagarara neza, kurwanya abrasion, kurwanya flake;
PC
Imikorere ya PC
PC ni ubwoko butagira ishusho, butagira impumuro nziza, butari uburozi, bubonerana cyane butagira ibara cyangwa ibara ry'umuhondo ritoya rya plastiki yububiko, hamwe nibintu byiza cyane byumubiri na mashini, cyane cyane birwanya ingaruka nziza, imbaraga zikomeye, imbaraga zunamye, imbaraga zo kwikuramo;Gukomera kwiza, ubushyuhe bwiza no guhangana nikirere, amabara yoroshye, kwinjiza amazi make.
Ubushyuhe bwo guhindura ubushyuhe bwa PC ni 135-143 ℃, inyanja ni nto kandi ubunini burahagaze.Ifite ubushyuhe bwiza nubushyuhe buke, imiterere yubukanishi butajegajega, ituze rinini, imiterere yamashanyarazi hamwe na flame retardant mubushyuhe bwinshi.Irashobora gukoreshwa igihe kirekire kuri -60 ~ 120 ℃.
Ihamye kumucyo, ariko ntishobora kwihanganira urumuri rwa UV, guhangana nikirere cyiza;Kurwanya amavuta, kurwanya aside, kurwanya alkali, aside ya okiside na amine, ketone, gushonga muri hydrocarbone ya chlorine na solide ya aromatic, bikabuza imiterere ya bagiteri, ibiranga flame retardant hamwe no kurwanya umwanda, igihe kirekire mumazi byoroshye gutera hydrolysis no guturika, ibibi ni kubera imbaraga zumunaniro muke, byoroshye kubyara imihangayiko, kwihanganira nabi, kutagira amazi meza, kutambara neza.Gutera inshinge za PC, gusohora, kubumba, gushushanya, gucapa, guhuza, gutwikira no gutunganya, uburyo bwingenzi bwo gutunganya ni ugutera inshinge.
Ibikorwa biranga PC
Ibikoresho bya PC byunvikana cyane nubushyuhe, gushonga kwayo gushonga hamwe no kwiyongera kwubushyuhe kandi bikagabanuka cyane, umuvuduko wihuse, ntabwo wumva igitutu, kugirango ubashe kunoza imikorere, gufata uburyo bwo gushyushya.Ibikoresho bya PC mbere yo gutunganya kugirango byume neza (120 ℃, 3 ~ 4) guhatira guhindagurika cyane.Ingaruka zikomeye zikomeye, birashobora rero kuba ubukonje, gushushanya ubukonje, gukonjesha gukonje hamwe nubundi buryo bukonje.Ibikoresho bya PC bigomba kubumbabumbwa mubihe byubushyuhe bwo hejuru, ubushyuhe bwinshi nubushyuhe bwinshi n'umuvuduko muke.Kuri soko ntoya, inshinge nke zigomba gukoreshwa.Kubundi bwoko bwa soko, inshinge yihuta igomba gukoreshwa.
Kugenzura ubushyuhe bwubushyuhe muri 80-110 better nibyiza, gukora ubushyuhe muri 280-320 ℃ birakwiye.

PC eshatu zikoreshwa ni inganda ziteranirizwamo ibirahure, inganda zikora amamodoka na elegitoroniki, inganda zamashanyarazi, zikurikirwa nibice byimashini zinganda, disiki optique, imyenda ya gisivili, mudasobwa nibindi bikoresho byo mu biro, ubuvuzi nubuvuzi, firime, imyidagaduro nibikoresho byo gukingira
PBT
Imikorere ya PBT
PBT ni kimwe mu bikoresho bikomeye bya tekinoroji ya termoplastique, ni ibikoresho bya kirisiti ya kirisiti, ifite imiti ihamye cyane, imbaraga za mashini, imiterere y’amashanyarazi hamwe nubushyuhe bwumuriro.Ibi bikoresho bifite umutekano muke mubidukikije byinshi, kandi ibiranga PBT biranga intege nke cyane.
Gushonga (225% ℃) hamwe nubushyuhe bwo hejuru bwubushyuhe buri munsi yibikoresho bya PET.Veka koroshya ubushyuhe ni 170 ℃.Ubushyuhe bwikirahure buri hagati ya 22 ℃ na 43 ℃.
Bitewe nigipimo kinini cyo korohereza PBT, ubukonje bwacyo buri hasi cyane, kandi igihe cyinzira yo gutunganya ibice bya plastiki muri rusange ni gito.
Ibiranga inzira ya PBT
Kuma: Ibi bikoresho hydrolyzes byoroshye mubushyuhe bwinshi, bityo rero ni ngombwa kuyumisha mbere yo kuyitunganya.Icyifuzo cyo kumisha ikirere ni 120C, amasaha 6-8, cyangwa 150 ℃, amasaha 2-4.Ubushuhe bugomba kuba munsi ya 0,03%.Niba ukoresheje icyuma cyitwa hygroscopique, icyifuzo cyo gukama ni 150 ° C mumasaha 2.5.Ubushyuhe bwo gutunganya ni 225 ~ 275 ℃, naho ubushyuhe busabwa ni 250 ℃.Kubintu bidahinduka ubushyuhe bwubushyuhe ni 40 ~ 60 ℃.
Umuyoboro ukonjesha wububiko ugomba kuba wateguwe neza kugirango ugabanye ibice bya plastiki.Ubushyuhe bugomba gutakara vuba kandi buringaniye.Birasabwa ko diameter yumubyimba ukonjesha ari 12mm.Umuvuduko wo gutera inshinge uringaniye (kugeza kuri 1500bar ntarengwa), kandi igipimo cyo gutera inshinge kigomba kwihuta bishoboka (kuko PBT ikomera vuba).
Abiruka n'irembo: Abiruka bazenguruka basabwa kongera ihererekanyabubasha.
