Varnish yimisemburo ikoreshwa mugutera inda amashanyarazi hamwe nu kuzunguruka kugirango yuzuze icyuho kirimo, kugirango insinga za coil hamwe ninsinga nibindi bikoresho byiziritse bihujwe hamwe kugirango bitezimbere ingufu zamashanyarazi, imiterere yubukanishi, imiyoboro yubushyuhe hamwe nuburinzi bwamashanyarazi coil. Madamu Can azagirana ikiganiro gito nawe kubijyanye na langi yo gutera inda uyumunsi, yizeye ko azafasha mugucunga ubuziranenge.
1 Ibisabwa byibanze kumashanyarazi yamashanyarazi
● Ubukonje buke nibintu byinshi bikomeye kugirango byemeze neza kandi bisige irangi;
Stability Guhagarara neza mugihe cyo kubika no gukoresha;
Ibiranga gukiza no gukama, gukira vuba, ubushyuhe buke, kumisha imbere;
Strength Imbaraga zihuza cyane, kugirango ibikoresho byamashanyarazi bishobora kwihanganira umuvuduko mwinshi ningaruka zingufu za mashini;
● Bihujwe nibindi bikoresho bigize;
Performance Imikorere myiza y’ibidukikije.
2 Gutondekanya nibiranga langish
Varnish yo gukuramo inda. Varnish ya solvent yinjizamo ibishishwa birimo ibishishwa, kandi ibiyirimo bikomeye (igice kinini) mubisanzwe biri hagati ya 40% na 70%. Varnish ya solvent yinjiza hamwe nibintu bikomeye birenga 70% byitwa lanish-solvent impregnation varnish, nanone bita varnish-ikomeye cyane.
Varnish ya solvent yinjiza ifite ububiko bwiza bwo kubika, gutembera neza hamwe no gukora firime, kandi birahendutse, ariko igihe cyo guteka no guteka ni kirekire, kandi ibisigara bisigaye bizatera icyuho mubintu byatewe. Umuvuduko ukabije utera kandi kwanduza ibidukikije n’imyanda, kandi ikoreshwa ni rito. Ikoreshwa cyane mugutera indamoteri ntoyan'amashanyarazi.
Varnish idashobora kwangirika mubisanzwe yatewe no kwibizwa, kandi kwinjiza vacuum no gutonyanga nabyo birashobora gukoreshwa.
Varnish idashobora kwangirika ivura vuba, ifite igihe gito cyo kwibira no guteka, ntigifite icyuho cyumwuka mumyanya yatewe, ifite ubunyangamugayo bwiza, kandi ifite amashanyarazi menshi nubukanishi. Varnish idashobora kwangirika yamashanyarazi yarazamuwe cyane kandi ikoreshwa kugirango isimbuze langi idafite imisemburo idafite amashanyarazi mumashanyarazi menshi, moteri, nini nini, imirongo yihuta cyane, hamwe na moteri yihariye hamwe nibikoresho byamashanyarazi. Ariko, igihe cyo kubika langish-yubusa idashobora kwangirika ni ngufi. Varnish idashobora kwangirika irashobora kwinjizwa no kwibizwa, guhora kwibiza, kwibiza, gutonyanga kwibiza no kwibiza umuvuduko.
3 Icyitonderwa cyo gukoresha langish
Management Imicungire myiza yimisemburo yo kwisiga mugihe ikoreshwa. Irangi ridafite umusemburo ni polymerizable resin igizwe. Ubwoko butandukanye bwibishishwa bidafite amarangi bizatera-polymerize kurwego rutandukanye mugihe cyo kubika no gukoresha. Imicungire idahwitse izihutisha iyi-polymerisation. Iyo irangi ridafite ibishishwa mubikoresho byo gutera akabariro ritanga gel, bizahita bikomera kandi biveho muminsi 1 kugeza 2, bitera impanuka nigihombo. Kubwibyo, ubuziranenge bw irangi ryinjira mu marangi rikoreshwa rigomba gucungwa neza, kandi hagomba gufatwa ingamba kugirango irangi ryiza rihamye.
(1) Kurikirana buri gihe no gukurikirana ubwiza bwirangi ryinjira mugukoresha. Ibikoresho byo kugenzura hamwe ninzinguzingo zishobora gutegurwa ukurikije irangi ryinjira, ibikoresho byo gutera inda hamwe ninshingano zo kubyaza umusaruro. Ubugenzuzi muri rusange burimo ubucucike, ubucucike, igihe cya gel, ibirimo ubuhehere nibirimo bikora neza. Niba indangagaciro yubuziranenge irangi irenze urugero rwo hejuru rwigenzura ryimbere, irangi rishya cyangwa izindi ngamba bigomba guhita bifatwa kugirango bihindurwe.
(2) Irinde ubushuhe nibindi byanduye kwinjira mwirangi. Epoxy cyangwa polyester solvent-idafite irangi ryinjiza irumva neza cyane. Ubwinshi bwamazi yinjira muri sisitemu bizatera ubwiza bwirangi kuzamuka vuba. Ubushuhe n’umwanda bigomba kubuzwa kwinjira mu irangi mugihe cyo gutwara, kubika no gukoresha irangi ryinjira. Amazi, umwuka hamwe na molekile nkeya ihindagurika ivanze irangi irashobora gukurwaho no guhumeka no gusiga irangi ibikoresho byangiza, kandi amazi yo gusiga irangi arashobora kuyungurura nibikoresho byo kuyungurura. Imyanda iri mu irangi ihora iyungurura kugirango isukure neza.
(3) Hitamo neza ubushyuhe bwo gutwita kugirango ubwiza bwirangi bugere ku giciro cyagenwe. Ibi birashobora gutoranywa hashingiwe ku bushyuhe-bushyuhe bwo kugabanuka bwirangi, mugihe urebye itandukaniro riri hagati yimirimo ikonje ikonje hamwe nakazi gashyushye. Niba ubushyuhe bwo kugabanuka ari hejuru cyane, bizagira ingaruka mbi kumyumvire ihamye y irangi; niba ubushyuhe bwo kugabanuka ari buke cyane, ibishishwa bizaba byinshi kandi ingaruka zo kwibiza zizaba mbi.
.
(5) Ongeraho irangi rishya buri gihe. Ongeraho inzinguzingo nubunini biterwa ninshingano yo gukora hamwe nimiterere y irangi. Mugushyiramo irangi rishya mubikorwa bisanzwe byumusaruro, irangi ryinjira muri tank rishobora gukoreshwa neza mugihe kirekire.
(6) Ububiko buke bugabanya umuvuduko wa polymerisiyasi yihuta. Ubushyuhe bwo kubika burashobora kugenzurwa munsi ya 10 ° C. Kumwanya muremure udakoreshwa cyangwa uteganijwe, ubushyuhe bwububiko bugomba no kuba munsi, nka -5 ° C.
Kubirangi byo gusiga irangi, icyibandwaho ni ugusuzuma buri gihe ubwinshi nubwiza bwirangi kugirango bigumane murwego rwo kugenzura.
● Ingaruka zumwanda mugukiza irangi rya polyester idahagije. Imyitozo yerekanye ko ibikoresho nkumuringa na fenoline bigira ingaruka zitinda gukira irangi rya polyester idahagije. Ibindi bikoresho bimwe na bimwe, nka reberi hamwe ninsinga zometseho amavuta, bizashonga cyangwa kubyimba na styrene ikora monomer mugisiga irangi, bigatuma ubuso bwibikorwa byatewe.
Issues Ibibazo byo guhuza. Ibizamini byo guhuza bigomba gukorwa kugirango irangi ryinjira ryinjizwe neza nibindi bikoresho bigize sisitemu yo kubika.
Gukemura ibibazo. Amavuta yo kwisiga ashingiye kumashanyarazi arimo ubwinshi bwumuti. Mubisanzwe, gutera kabiri cyangwa byinshi, guteka hamwe nubushyuhe buhoro buhoro byongera uburyo bwo guteka bikoreshwa mukurinda pinholes cyangwa icyuho muri firime irangi no kunoza imikorere nubuzima bwo kubika coil. Uburyo bwo guteka bwa langi zidafite imisemburo zidafite ubukana zigomba kwitonda kugirango wirinde kole nyinshi. Guteka kuzunguruka birashobora kugabanya neza imigozi ya kole.
Issues Ibibazo byangiza ibidukikije. Hagomba gufatwa ingamba zikwiye zo kugenzura imyuka yumuti na styrene byasohotse mugihe cyo gutera akabariro no guteka mugihe cyagenwe cyemewe.
