Imikandara ya PTFE , izwi kandi ku izina rya Teflon, ikozwe mu rwego rwo guhangana n’ubushyuhe bukabije bw’inganda bitewe n’imiterere yihariye y’imiti n’imiterere y’umubiri. Ibanga riri mu kurwanya ubushyuhe budasanzwe bwa polytetrafluoroethylene (PTFE), bugumana ubusugire bw’imiterere n’imiterere idakomeye ndetse no mu bushyuhe buri hagati ya -70 ° C na 260 ° C (-94 ° F kugeza 500 ° F). Iyi mikorere idasanzwe yubushyuhe iterwa na karubone-fluor ikomeye muri molekile ya PTFE, itera inzitizi yo gukingira ubushyuhe. Byongeye kandi, coefficente nkeya yo kugabanya imikandara ya PTFE igabanya ubushyuhe mugihe gikora, bikongera ubushobozi bwabo bwo gukora mubushyuhe bwo hejuru. Ibi biranga bituma imikandara ya convoyeur ya PTFE ari ingenzi mu nganda aho ubushyuhe bukabije cyangwa imbeho ari ikibazo gihoraho.

Siyanse Inyuma ya PTFE Kurwanya Ubushyuhe
Imiterere ya molekulari hamwe nubushyuhe bwumuriro
Ubushyuhe budasanzwe bwumukandara wa PTFE buturuka kumiterere yihariye ya molekile. PTFE igizwe n'iminyururu ndende ya atome ya karubone ihujwe neza na atome ya fluor. Iyi gahunda ikora molekile ihamye idasanzwe hamwe ningufu nyinshi zo gutandukana. Imiyoboro ya karubone-fluor iri mubikomeye muri chimie organic, bisaba imbaraga nyinshi zo gucika. Ihindagurika rya molekuline risobanurwa no kurwanya ubushyuhe budasanzwe, butuma imikandara ya PTFE igumana ubusugire bwimiterere nibikorwa biranga ubushyuhe bugari.
Coefficient nkeya yo guterana amagambo
Ikindi kintu cyingenzi kigira uruhare mukurwanya ubushyuhe bwimikandara ya PTFE ni coefficient nkeya idasanzwe yo guterana. Uyu mutungo nigisubizo cyintege nke za intermolecular hagati yiminyururu ya PTFE, ibemerera kunyerera hagati yabo hamwe na resistance nkeya. Mubikorwa byinganda, iyi friction yo hasi iranga bivuze ko imikandara ya convoyeur ya PTFE itanga ubushyuhe buke binyuze mumashanyarazi mugihe ikora. Kugabanya ubushyuhe bugira akamaro cyane cyane mubushyuhe bwo hejuru, kuko bifasha mukurinda ingufu zumuriro wongeyeho kumukandara.
Ibikoresho byo Kwagura Ubushyuhe
PTFE yerekana coefficient nkeya yo kwagura ubushyuhe ugereranije nizindi polymers nyinshi. Uyu mutungo ningirakamaro mugukomeza guhagarara kurwego rwimihindagurikire yubushyuhe. Mumukandara wa convoyeur, ibipimo bihoraho nibyingenzi mugukurikirana neza no guhuza. Kwiyongera k'ubushyuhe buke bwa PTFE byemeza ko imikandara igumana imiterere nubunini bwayo nubwo ihura nubushyuhe bukabije, bikagira uruhare mu kwizerwa mubikorwa bitandukanye byinganda.
Gushyira umukandara wa PTFE murwego rwo hejuru-Ubushyuhe
Gutunganya ibiryo no guteka
Mu nganda zibiribwa, imikandara ya PTFE ningirakamaro mubisabwa ubushyuhe bwo hejuru nko guteka, gusya, no gukonjesha. Iyi mikandara irashobora kwihanganira ubushyuhe bukabije bwitanura ryinganda mugihe itanga ubuso butari inkoni ibuza ibicuruzwa byokurya gukomera. Ubushyuhe bwo kurwanya imikandara ya PTFE butanga ubuziranenge bwibicuruzwa kandi bikagabanya ibyago byo kwangirika cyangwa kwanduza. Kuva kumirongo itanga imigati kugeza gutunganya ibiryo byafunzwe, imikandara ya convoyeur ya Teflon igumana ubunyangamugayo n'imikorere, kabone niyo byahinduka vuba.
Gukora imiti na farumasi
Inganda zikora imiti n’imiti akenshi zirimo inzira zisaba guhura nibintu byangirika nubushyuhe bukabije. Imikandara ya PTFE iratangaje muri ibi bidukikije kubera ubudahangarwa bw’imiti no kurwanya ubushyuhe. Barashobora gutwara ibikoresho bifatika binyuze mumashanyarazi ashyushye cyangwa ibyumba bikonjesha bititesha agaciro cyangwa byanduza ibicuruzwa. Uku kwizerwa ni ingenzi mu kubungabunga isuku n’imikorere yimiti n’imiti yihariye mugihe cyo gukora.
Gutunganya imyenda no gutunganya imyenda
Inganda zimyenda zishingiye cyane kubushyuhe no gukama kugirango zikore kandi zirangize imyenda. Imikandara ya PTFE nibyiza kuriyi porogaramu kuko irashobora kwihanganira ubushyuhe bwo hejuru bwitanura ryubushyuhe mugihe itanga ubuso bworoshye, butari inkoni kumyenda yoroshye. Ubushyuhe butajegajega bwa PTFE butuma impagarara zihoraho hamwe nuburinganire bwukuri bwumukandara wa convoyeur, ni ngombwa kugirango umuntu agere ku bwiza bwimyenda. Kuva mubikorwa bya fibre synthique kugeza kumyenda yimyenda, umukandara wa Teflon ugira uruhare runini mugutunganya imyenda yubushyuhe bwo hejuru.
Kuzamura imikorere ya PTFE Umukandara mubihe bikabije
Kwubaka
Kugirango urusheho kunoza imikorere yimikandara ya PTFE mubushyuhe bukabije, abayikora akenshi bashiramo ibyubaka. Ibi bishobora kubamo gushimangira urwego rwa PTFE hamwe na fiberglass cyangwa ibindi bikoresho bikomeye. Kongera imbaraga za fiberglass byongera umukandara imbaraga zingirakamaro hamwe no guhagarara neza, cyane cyane mugihe ukora mubihe by'ubushyuhe bwo hejuru bishobora gutera kwaguka. Izi nyubako zikomatanya zemerera imikandara ya PTFE kugumana imiterere no gukurikirana imitungo kabone niyo yaba ihuye nubushyuhe bukabije bwumuriro, bigatuma imikorere yizewe isaba inganda zikoreshwa.
Guhindura Ubuso
Ubuhanga bugezweho bwo guhindura ibintu bushobora kongera ubushyuhe bwimikorere nimikorere ya PTFE . Ubuvuzi nka plasma etching cyangwa imiti ihindura imiti irashobora guhindura imiterere yimiterere yibikoresho bya PTFE, kunoza imiterere yabyo cyangwa kurema ibice byanditse kubikorwa byihariye. Izi mpinduka zirashobora guhuzwa kugirango hongerwe imikorere yumukandara cyane cyane ahantu hafite ubushyuhe bwo hejuru, nko kunoza imikorere yubushyuhe cyangwa kuzamura ibicuruzwa bisohora. Muguhuza neza ibiranga ubuso, ababikora barashobora gukora imikandara ya PTFE iruta iyindi mikorere yubushyuhe bukabije.
Sisitemu yo gucunga ubushyuhe
Rimwe na rimwe, guhuza sisitemu yo gucunga ubushyuhe birashobora kurushaho kwagura ubushobozi bwimikandara ya PTFE mukirere gikabije. Ibi birashobora gushiramo uburyo bwo gukonjesha muburyo bwa convoyeur cyangwa gukoresha imashini yihariye irwanya ubushyuhe hamwe ninkunga. Mugucunga neza umutwaro wumuriro kumukandara, sisitemu irashobora gufasha kubungabunga imikorere myiza no kongera igihe cyumukandara. Uburyo bwiza bwo gucunga neza ubushyuhe butuma imikandara ya PTFE ikora neza muburyo bwogukora inganda zo mu rwego rwo hejuru cyane, bigasunika imbibi zubushyuhe bumaze kugaragara.
Umwanzuro
Imikandara ya PTFE ihagarara nkubuhamya bwibikoresho bishya siyanse, itanga imikorere ntagereranywa mubushuhe bukabije. Imiterere yihariye ya molekile, imiterere yo guterana hasi, hamwe nubushyuhe bwumuriro bituma iba ingenzi mubikorwa bitandukanye byubushyuhe bwo hejuru. Kuva gutunganya ibiryo kugeza mubukora imiti, iyi mikandara ya Teflon ikomeje gusunika imipaka yibishoboka muburyo bwa tekinoroji ya convoyeur. Mu gihe inganda zigenda zitera imbere kandi zigahura n’ibibazo bishya by’ubushyuhe, nta gushidikanya ko imikandara ya PTFE izagira uruhare runini mu gutsinda izo nzitizi, bigatuma umusaruro unoze kandi wizewe mu nzego zitandukanye.
