PTFE (polytetrafluoroethylene)na polyester (nka PET, PBT, nibindi) nibikoresho bibiri bitandukanye rwose bya polymer. Bafite itandukaniro rikomeye muburyo bwa shimi, ibiranga imikorere nimirima ikoreshwa. Ibikurikira nigereranya rirambuye:
1. Imiterere yimiti nibigize
PTFE (polytetrafluoroethylene)
●Imiterere: Igizwe na karubone atom ya karubone na atome ya fluor yuzuye (-CF₂-CF₂-), kandi ni fluoropolymer.
●Ibiranga: Ububiko bukomeye bwa karubone-fluor butanga ubudahangarwa bukabije bwimiti no kurwanya ikirere.
Polyester
●Imiterere: Urunigi nyamukuru rurimo itsinda rya ester (-COO-), nka PET (polyethylene terephthalate) na PBT (polybutylene terephthalate).
●Ibiranga: Inkunga ya ester itanga imbaraga zumukanishi no gutunganywa, ariko imiti ihagaze neza iri munsi ya PTFE.
Kugereranya imikorere
| Ibiranga | PTFE | Polyester (nka PET) |
| Kurwanya ubushyuhe | - Gukomeza gukoresha ubushyuhe: -200 ° C kugeza 260 ° C. | - PET: -40 ° C kugeza 70 ° C (igihe kirekire) |
| Imiti ihamye | Kurwanya acide hafi ya zose, alkalis hamwe nuwashonga ("umwami wa plastike") | Kurwanya acide nkeya na alkalis, byoroshye kwangirika na acide ikomeye na alkalis |
| Coefficient de frais | Hasi cyane (0.04, kwiyitirira) | Hejuru (akeneye inyongera kugirango atezimbere) |
| Imbaraga za mashini | Hasi, byoroshye kunyerera | Hejuru (PET ikoreshwa kenshi muri fibre n'amacupa) |
| Ibikoresho bya dielectric | Byiza cyane (ibikoresho byihuta cyane) | Nibyiza (ariko byumva neza) |
| Gutunganya ingorane | Biragoye gushonga inzira (ikeneye gucumura) | Irashobora guterwa no gusohora (byoroshye gutunganya) |
Imirima yo gusaba
PTFE: ikoreshwa cyane mu kirere, ibikoresho bya elegitoroniki, inganda z’imiti, gutunganya ibiribwa, ubuvuzi n’izindi nzego, akenshi bikoreshwa mu gukora kashe, ibyuma, impuzu, ibikoresho byangiza, n'ibindi.
Polyester: ikoreshwa cyane cyane mumyenda yimyenda, amacupa ya plastike, firime, plastiki yubuhanga nizindi nzego
Ibitekerezo bisanzwe
Igipfundikizo kidafite inkoni: PTFE (Teflon) ikoreshwa mubikono bidafite inkoni, mugihe polyester idashobora kwihanganira guteka ubushyuhe bwinshi.
Umwanya wa fibre: Fibre polyester (nka polyester) nibikoresho byingenzi byimyambaro, naPTFEzikoreshwa gusa mubikorwa byihariye (nkimyenda ikingira imiti)
Nigute PTFE ikoreshwa mubikorwa byinganda?
PTFE (polytetrafluoroethylene) ifite uburyo bwinshi bwo gukoresha mu nganda z’ibiribwa, bitewe ahanini n’imiti ihagaze neza, irwanya ubushyuhe bwinshi, kudafatana hamwe na coefficient de fraisse nkeya. Ibikurikira nuburyo bukoreshwa bwa PTFE mu nganda zibiribwa:
1. Ibikoresho byo gutunganya ibiryo
Ipitingi ya PTFE ikoreshwa cyane mugutondekanya no gutunganya ibikoresho byo gutunganya ibiryo. Kudakomera kwayo birashobora kubuza ibiryo kwizirika hejuru yibikoresho mugihe cyo gutunganya, bityo koroshya inzira yisuku no kuzamura umusaruro. Kurugero, mubikoresho nk'itanura, amato, hamwe na blender, gutwikira PTFE birashobora kwemeza ko ibiryo bitubahiriza mugihe cyo gutunganya ubushyuhe bwinshi mugihe bikomeza ubusugire nubwiza bwibiryo.
2. Umukandara wa convoyeur hamwe n'umukandara wa convoyeur
Imikandara ya PTFE isize imikandara hamwe n'umukandara wa convoyeur bikoreshwa kenshi mugutunganya ibiryo byakozwe cyane, nko guteka no gutanga amagi, bacon, sosiso, inkoko, na hamburg. Coefficient nkeya yo guterana hamwe nubushyuhe bwo hejuru bwibi bikoresho bituma ituma ikora neza ahantu h’ubushyuhe bwo hejuru idateye kwanduza ibiryo.
3. Amabati yo mu rwego rwo hejuru
Amabati ya PTFE akoreshwa cyane mu gutwara ibiryo n'ibinyobwa, birimo vino, byeri, ibikomoka ku mata, sirupe n'ibirungo. Imiti y’imiti ituma itagira ingaruka ku bwiza bw’ibicuruzwa byatanzwe mu bushyuhe bwa -60°C kugeza 260°C, kandi ntizerekana ibara, uburyohe cyangwa umunuko. Byongeye kandi, ama shitingi ya PTFE yujuje ubuziranenge bwa FDA kugirango umutekano wibiribwa.
4. Ikidodo hamwe na gaseke
Ikirangantego cya PTFE na gasketi bikoreshwa muguhuza imiyoboro, indangantego hamwe nudupapuro twibikoresho byo gutunganya ibiryo. Barashobora kurwanya ruswa ituruka kumiti itandukanye mugihe ikomeje guhagarara neza mubushyuhe bwo hejuru. Ikidodo kirashobora gukumira neza ibiribwa kwanduzwa mugihe cyo gutunganya mugihe byoroshe gusukura no gufata neza ibikoresho.
5. Ibikoresho byo gupakira ibiryo
PTFE ikoreshwa kandi mubikoresho byo gupakira ibiryo, nkibishishwa bidafite inkoni, impapuro zo guteka, nibindi. Ibi bikoresho byemeza ko ibiryo bitubahiriza mugihe cyo gupakira no guteka, mugihe bikomeza isuku numutekano wibiribwa.
6. Ibindi bikorwa
PTFE irashobora kandi gukoreshwa mubikoresho, gutwara ibihuru hamwe nu bikoresho bya pulasitiki mu gutunganya ibiryo, bishobora kunoza imyambarire no kwangirika kw ibikoresho mugihe bigabanya amafaranga yo kubungabunga.
Ibitekerezo byumutekano
Nubwo PTFE ifite imitungo myinshi myiza, uracyakeneye kwita kumutekano wayo mugihe uyikoresha mubiribwa. PTFE irashobora kurekura imyuka ya gaze yangiza mubushyuhe bwinshi, birakenewe rero kugenzura ubushyuhe bwo gukoresha no kwirinda ubushyuhe bwigihe kirekire. Byongeye kandi, ni ngombwa guhitamo ibikoresho bya PTFE byujuje ibyangombwa bisabwa.
