Mu bikorwa nk’ugutera umuriro, gukingira ubushuhe bw’ubuhinga bwa none, no gukingira uruzitiro, ubushobozi bwo guhagarika urubeya, ubushobozi bwo guhangana n’ubushuhe bwinshi, n’ugukingira umuriro w’ibikoresho vy’ifu ni vyo bigena ata guca ku ruhande ingorane z’umuriro wo mu mahugurwa n’umwimbu w’ibicuruzwa. Ivyo bikoresho bitatu vy’ingenzi biri kw’isoko-ifu ya EVA, ifu ya EPDM, n’ifu ya silikoni idashobora gutera umuriro-biratandukanye cane mu bijanye n’ubushobozi bwo guhangana n’umuriro. Aha hepfo hariho ukugereranya gutomoye ku bijanye n’urugero rw’ugusha, inyifato y’ubushuhe bwinshi-, ubumara bw’umwotsi, n’ingene bikoreshwa.
一. EVA ifu (ibikoresho vy'ifu bishoboka)
EVA y’akavukire ni ikintu gishobora kwaka cane gifise urugero rw’umwuka w’ikirere rwo hejuru cane rwa 17–19 gusa; ivyerekanwa bitahinduwe bihuye n’igipimo c’uguturika UL94 HB. Irasha ubudasiba iyo ishikiwe n’imbeya zifunguye, igaca ihinduka amatonyanga ashobora guturitsa ibipande n’ibikoresho biyikikuje, ikarekura umwotsi mwinshi w’agahomerabunwa be n’ibintu bishobora guhungabana igihe iriko irasha.
Naho iyo vyongeweko ibintu bigabanya umuriro kugira ngo bivemwo EVA ishobora guhangana n’umuriro, ishika gusa ku rugero rwa V-1/V-0 mu gihe gito kandi irafise ingorane zikomeye: iyo umuntu amara igihe kirekire ari mu bushuhe buri hejuru ya degre 80, ubushobozi bwo gukingira umuriro bwo mu mutima buragabanuka. inyuma yo gusubiramwo gushusha; ku bushuhe burenze degre 120 , ivyo bintu birayoroha kandi bikagabanuka, bikaba bituma bidakwiye rwose gukoreshwa mu bihe vy’ubushuhe bwinshi buhoraho bw’amashini ashushe ya PCB (arenga degre 200 ).
Inyungu imwe rudende ni uko igura amahera make; ni vyiza gusa ku gupfunyika ubushuhe bwo mu karere-n'ububiko bw'ubushuhe buke-, kandi birabujijwe cane gukoreshwa mu mirongo y'ubuhinga bw'ubushuhe bwinshi-.
2. EPDM (Etilene Propilene Diene Monomere) ifu (ifu rusangi-intumbero yo gukingira HVAC)
EPDM ifise ubuhinga bufise ubushobozi bwo guhangana n’ibihe bidasanzwe be n’ubushobozi bwo guhangana n’ikirere citwa ozone. Igikoresho caco cahinduwe gihuye n’ingingo ngenderwako za UL94 V-0 zo gukingira umuriro, kikaba gikora igice c’umuyagankuba kibuza umuriro gukwiragira mu gihe c’ugusha mu gihe gitanga amatonyanga makeyi y’umuriro kandi kigaragaza uburemere bw’umwotsi buke cane kuruta EVA.
Ariko rero, hariho urugero rwo hejuru rutomoye ku bushuhe bwayo burengeye -: ubushuhe buhoraho bw'igihe kirekire-buva gusa kuri -40 degrees gushika kuri 120 degrees , n'ubushuhe bw'igihe gito-burengeye 175 degrees . Gukomeza gushikirwa n’ubushuhe buri hejuru ya degre 180 buhorobuhoro bizotuma umuntu agira uburebure bworoshe kandi akabura ubushobozi bwo gukomera; urubeya-rushobora gusenyuka rugaca ruva ku bushuhe burenze degre 200 , gutyo rugatakaza ubushobozi bwarwo bwo kwikingira umuriro.
Ikoreshwa cane cane mu bikoresho vyo gutuma umuyaga ugera mu nzu, gukingira imiyoboro no kuyikingira, hamwe n’ugukingira ubushuhe bw’igihe gito -; ariko rero, ntibibereye gukoreshwa n’ibipande vy’ibipande vyinshi vya PCB canke uburyo bwo gufatanya ubushuhe bwinshi bwa HDI.

3. Urubeya-silicone y'ifu (ibikoresho vyemewe ku bikoresho vy'iponje vya PCB)
Ico gikoresho c’ifu cakozwe mu buryo bwihariye ku bikorwa vy’inganda bifise ubushuhe bwinshi, gifise ubuhinga busanzwe buhuye n’igipimo co gukingira umuriro gikomeye cane ca UL94 V{3}}0, bikaba bituma ari co kintu gishobora gukingira umuriro kuruta ibindi vyose mu mahitamwo atatu ariho.
Ibirango vy’uguturika: Irazima ningoga iyo ikoranye n’urubeya rwuguruye mu masegonda 10, yerekana gusa uguhinduka kw’umuriro gatoyi ku ruhande ata matosi y’umuriro ashonze; itanga umwotsi muto, nta halogène-igira kandi nta -ubumara igira, kandi ntirekura imyuka ishobora kwanduza ibipande vy’umuringa canke ibipande vy’imirongo.
Imbeho y’ubushuhe bwinshi-ishobora guhagarika ubushuhe: Ishobora kwihanganira igihe kirekire ubushuhe buva kuri degre 200–230 , kandi mbere n’igihe gito -ubushuhe burengeje urugero bushika kuri degre 250 mu gikoresho co gucapura ntibituma iryoha canke ngo isenyuke. Igishushanyo caco c’ingingo zipfutse-kitanga ubushuhe buhoraho; igikoresho co gukingira umuriro-ntigisohoka canke ngo kigasenyuke ku bushuhe bwinshi, ata kugabanya gukomeye kw’ubushobozi bwo guhangana n’umuriro inyuma y’ingendo zirenga igihumbi z’ugukomera kw’ubushuhe.
Inyungu nyamukuru: ikibiriti-kidafise kandi kidafise ibisigazwa, gifise ubushobozi bwo guhangana n’ibintu vyinshi kugira ngo gisubirwemwo mu gihe gihuye n’ibisabwa bitatu nyamukuru-ugukingira urubeya, gukingira umuvuduko uringaniye, n’ubushobozi bwo guhangana n’ubushuhe bwinshi -bituma gishobora gukoreshwa neza cane nk’umurongo wa P4 gukanda n'inguvu nshasha z'ubushuhe bwinshi-ibikorwa vyo kwikingira.
