Polysalfone (Psu) plastike nibintu bifatika bizwi kubwimbaro yacyo mubihe bikabije. Kuva mu bikoresho by'ubuvuzi kugera mu gice cya Aerospace, Psu itanga imbaraga zidasanzwe, kurwanya ubushyuhe, no gushikama imiti. Muri iyi nyandiko, uziga ibintu bidasanzwe bya PSU n'impamvu ari amahitamo yo hejuru mu nganda zitandukanye.
PSU ni iki?
Psu, cyangwa polysulfone, ni imikorere miremire izwiho imitungo myiza. Igizwe no gusubiramo ibice byamatsinda ya sulfone hamwe nimpeta nziza, bigatuma imiterere ikomeye kandi ihamye ya polymer.
Iyi miti idasanzwe iha Psu ibiranga ibintu byingenzi, nka:
Ugereranije nabandi thermoplastike, PSsu igaragara kubera ubushobozi bwayo bwo kubungabunga imitungo hejuru yubushyuhe bwinshi. Irashobora kwihanganira ubushyuhe kuva -10 ° F (-100 ° C) kugeza 300 ° F (150 ° C), kugirango bikwiranye no gusaba ibyifuzo.

Guhindura Polysulfone (Psu)
Mugihe PSU yamaze kwirata imitungo itangaje, irashobora kongera imbaraga binyuze muburyo butandukanye. Iyi mihindagurikire y'ikigereranyo yemerera PSU kuba ishyirwa ku ikoreshwa n'inganda runaka.
Ivangura ryayongereye
Kuvanga Psu hamwe nabandi polmer ninzira nziza yo kunoza imikorere yayo. Imbuga ebyiri zisanzwe ni:
Psu / P Burnds:
Kuvanga Psu hamwe na polyamide (pa) zongerera imitungo yacyo nubuka bwiza.
Imiterere ya kimwe cya parike ya PE nayo itezimbere kurwanya imiti ya rolond.
Izi mvange zihuza imbaraga zibikoresho byombi, bikavamo igikomangoma hamwe niterambere rusange.
Psu / PC bivanze:
Guhuza PSU hamwe na Polycarbonate (PC) birashobora kunoza imitungo yacyo mugihe ukomeza imikorere ya mashini.
Ariko, kubera imiterere ya amorfuus ya PC, ntaho bitera imbere mubuvuzi bwo kurwanya imiti.
Izi mvange ningirakamaro aho gahunda nziza zisabwa utabitanze imbaraga zubumashini.
INSHINGANO ZIKURIKIRA
Kwinjiza inyongera muri PSU birashobora kongera imitungo yayo. Uburyo bumwe busanzwe ni ugukoresha filers:
Filers:
Ongeraho abazuru kuri PSU barashobora kunoza imbaraga zamanishi na Medicalic.
Abagororwa basanzwe barimo fibre yikirahure, fibre ya karubone, hamwe na minerval filer nka talc cyangwa karubone ya calcium.
Guhitamo kwuzuza biterwa numutungo wihariye wifuzwa hamwe nibisabwa gusaba.

Imbonerahamwe: Abagororwa basanzwe bakoreshwa muri PS hamwe no kuzamura imitungo yabo
Guhitamo
Psu irashobora kuba yihariye kugirango yujuje ibyifuzo byihariye yinganda zitandukanye. Ingero ebyiri zizwi ni:
Aerospace:
Muri porogaramu ya Aerospace, Psu yakunze guhindurwa kugirango atezimbere ikibaya cyacyo no guhubuka.
Inzoti zimeze nkibikoresho bya fosifore cyangwa nanoclays birashobora kwinjizwa kugirango byongere imbaraga.
Byongeye kandi, gushimangira nka fibre ya karubone irashobora gukoreshwa kugirango wongere imbaraga-kuri-ibiro bya PSU kubice byoroheje byindege.
Ubuvuzi:
Kubisabwa mubuvuzi, Psu irashobora guhindurwa kugirango itezimbere biocompaTubisobanuro na sterizi.
Inyongera zirwanya zirashobora kwinjizwa kugirango birinde imikurire ya bagiteri nizindi mikorobe kubijyanye nibikoresho byubuvuzi.
Matrix Polymer irashobora kandi guhurizwa kugirango hamenyekane uburyo butandukanye bwo gusoza ibintu, nka Automedated cyangwa Gamma.
Izi ni ingero nke zukuntu PSU ishobora guhindurwa kubwinganda zihariye. Ibisobanuro bya PSU bituma habaho uburyo butabarika bushoboka, bikabikora ibintu byingenzi kugirango ibyifuzo byinshi.
Igishushanyo mbonera
Iyo ushushanyije ibicuruzwa hamwe na psiki, hari ibintu byinshi bikomeye byo gusuzuma kugirango ubone imikorere myiza.
Umutekano
Psu yahawe agaciro k'ububiko buke bwo kwaguka mu bushyuhe , bigatuma biba byiza mu bice bikeneye gukomeza ibipimo nyabyo.

Imashini zateguwe za PSU
Kugera kuri precisic ya plastic plastike isaba gusuzuma neza ibintu byinshi. Kumurongo, Gufata Imyitozo myiza, no Kwirinda kwanduza ni ngombwa kubisubizo byiza.
Gukomera
Gukata nigikorwa cyingenzi mubirindiro bya plastiki psisti. Ifasha kugabanya imihangayiko yimbere zishobora gutera gutontoma cyangwa kunanirwa imburagihe.
Ibikenewe kandi bikora kubikorwa byo gutabara bitera inkunga bidashobora gukanda. Porotokole ikwiye yo guhuza neza ibice bya PSU bikomeza gushikama kwabo hamwe nubutaka mugihe.
Gufata Imyitozo myiza
Guhitamo ikonjesha iburyo no gukurikiza imikorere myiza nibyingenzi kubisubizo byiza byo gufata neza. Ubwoko
Coolant ibereye:
Ibikorwa bidahumuriza, bikonjesha amazi, nko guhuriza hamwe umwuka no gutera mibi, bikwiranye cyane na PSU.
Batanga ubuso bwiza burashira no gukomeza kwihanganira hafi.
Irinde gukoresha coolaleum ishingiye kuri peteroli, kuko zishobora gutera no gutesha agaciro Psu.
Kwagura ubuzima buke:
Guhitamo neza ntabwo bireba ibisubizo byiza gusa ariko nabyo byagura ubuzima bwibikoresho.
Coolant igabanya ubushyuhe no guterana amagambo mugihe cyo kuvura, kugabanya kwambara kubikoresho.
Ibi biganisha kumwanya muremure wibikoresho, kugabanya ibiciro byo gusimbuza ibikoresho, no kunoza imbaraga muri rusange.

Imbonerahamwe: Ukwiriye ninyungu zo gukoresha Psu
Gukumira kwanduza
Kwirinda kwirinda ni ngombwa iyo gufata Psu, cyane cyane inganda zifite ibisabwa mu isuku, nka aeropace n'ubuvuzi.
Ingero zigereranya ingaruka zizanduza ibyuma zirimo:
Igikoresho cyibikoresho byubuvuzi cyasanze ibice by'icyuma byashyizwe mu ngingo za PSU itangwa, biganisha ku bicuruzwa bibuka kandi bikaze kw'imari.
Isosiyete ya Aerospace yahuye no kunanirwa imburagihe cya PSU kubera umwanda wicyuma, bikaviramo impungenge z'umutekano kandi zitanga umusaruro uhenze.
Kurinda ibintu nk'ibi, shyira mu bikorwa ingamba zo kurwanya kwanduza neza, nka:
Gusukura neza no kubungabunga ibikoresho byo gusiga
Kugenzura buri gihe ibice byafashwe byanduye
Gukoresha sisitemu ya Hepa FilTration kugirango ukomeze ibidukikije bisukuye
Gukurikiza cyane Protocole ya Protocole hamwe nuburyo busanzwe bwo gukora
Umwanzuro
Polysulfone (Psu) igaragara cyane kubushyuhe bwo hejuru no kurwanya imiti . Itanga imbaraga za mashini nigikorwa cyinshi , bigatuma ikwirakwira munganda nkimyanda nibikoresho byubuvuzi.
Mugihe uhitamo PSU, asigaye nibikorwa . amafaranga Igiciro cyo hejuru cya Psu ntigishobora guhora gikenewe kugirango ibyifuzo bike bisabwa. neza Gutunganya no kwanduza kwirinda ni urufunguzo rwo kuganza imikorere yacyo.
INAMA: Birashoboka ko ushobora kuba ushishikajwe na plastique yose
