Isembozo cya Polyurethane gifite imikorere myinshi

Ibisobanuro

Ushobora gutekereza ko ifunze ya polyurethane ifite imikorere myinshi ari ubwoko bwihariye bw'ibikoresho bifunga bihuza ubworoherane, imbaraga, n'uburyo bwo gukora ibintu bitandukanye. Iyi funze ikora neza ku buso bwinshi, nko mu giti, mu byuma, muri sima na pulasitiki. Iyo uyikoresheje, ubona ikintu kiramba kigasubira ku ishusho yacyo ya mbere. Ntigicika cyangwa ngo gicike byoroshye, ndetse n'iyo ubuso bwimuka cyangwa buhinduye imiterere. Ushobora kuyishingikirizaho haba mu mishinga yo mu nzu no hanze kuko irwanya amazi, imiti, n'impinduka z'ubushyuhe.

Imitungo y'ingenzi

Ifu ya polyurethane ifite imikorere myinshi iragaragara cyane kubera imiterere yayo ya elastomeric. Iyi miterere ituma ifu ya polyurethane ikomeye, irambura, kandi ishobora gukira nyuma yo gukururwa cyangwa gukandagirwa. Ibizamini byo muri laboratwari bigaragaza ibintu byinshi by'ingenzi:

● Imbaraga zo gukurura no kurekura igihe cyo kuruhukabipimwa hakoreshejwe ingero zihariye n'ibikoresho byo gupima umuvuduko. Ibi bivuze ko agakoresho gafunga gashobora kwaguka kure mbere yo gucika.

● Ubukomere bugenzurwa no gukurura uduce duto tw'icyuma gifunga. Ubona ibikoresho bidacika byoroshye.

● Ubudahangarwa bw'ibitobo bupimwa hakoreshejwe urushinge rw'icyuma mu gifunga. Bisaba imbaraga nyinshi kugira ngo bimeneke.

● Ibizamini byo gushyiramo ibikoresho mu buryo bw'izunguruka bigaragaza ko agakoresho gafunga gashobora kwaguka inshuro nyinshi ariko kagasubira ku ishusho yako ya mbere.

● Ubushobozi bwo kwivura bupimirwa no gukata no kongera guhuza agakoresho gafunga, hanyuma hagapimwa uburyo gasubirana imbaraga n'ubushobozi bwako bwo kunanuka.

● Ingufu zo gufatana zigeragezwa no gukuraho ibyuma bifatanye n'icyuma gifunga. Ubona isano ikomeye ikomeza kwihanganira ibintu.

Itsindaimiterere ya molekile y'icyuma gifungaNanone kandi ni ingenzi. Abahanga mu bya siyansi bahindura uruvange rw'ibice byoroshye n'ibikomeye kugira ngo bongere imbaraga n'uburemere. Bakoresha ibikoresho nka polydimethylsiloxane (PDMS) na polypropylene oxide (PPO) kugira ngo batume agakoresho gafunga ibintu gashobora koroha kandi kadahinduka bitewe n'impinduka z'ubushyuhe. Agakoresho gafunga ibintu gahora gafite ubushyuhe buri hagati ya -50 °F na 176 °F, bityo ushobora kugakoresha mu bihe bitandukanye.

Iyo ugereranyije polyurethane sealant ifite imikorere myinshi na silicone cyangwa acrylic sealants, ubona ibyiza bisobanutse.Ibifunga bya polyurethane bikurura neza urujya n'uruza n'uruza rw'ibintu. Bikora umupfundikizo ukomeye, woroshye kandi udapfa amazi. Udupfundikizo twa silikoni na two dutanga ubushobozi bwo koroshya no kwirinda amazi, ariko udupfundikizo twa polyurethane twongera imbaraga zo gukomeza no kurwanya imiti. Udupfundikizo twa acrylic ntabwo twaguka cyane kandi dushobora kugabanuka cyangwa kwangirika uko igihe kigenda. Niba ukeneye umupfundikizo wo kwagura ingingo, amadirishya, cyangwa ahantu himuka, polyurethane ni yo mahitamo meza.

Gutegura ubuso

Ugomba gutegura ubuso witonze mbere yo gukoresha agakoresho gafunga polyurethane gafite imikorere myinshi.Ahantu hasukuye, humutse kandi hatarimo ivumbifasha agafunga gufata neza no kuramba igihe kirekire.Kuraho amavuta yose, amavuta, ingese, n'irangi rishajeUshobora gukoresha isabune, imiti ivangavanze nka isopropyl alcohol, cyangwa uburyo bwa mekanike nko gusya cyangwa gusuka insinga. Ku buso bumwe na bumwe, busukure ukoresheje sandpaper cyangwa brush y'insinga kugira ngo wongere gufata neza. Buri gihe reba amabwiriza y'uwakoze ibikoresho kugira ngo ubone uburyo bwihariye bwo kuvura cyangwa gukoresha primer. Niba ubuso butose cyangwa bwanduye, agafunga gashobora kudafatana neza.

Intambwe zo Gusaba

Kurikiza izi ntambwe kugira ngo ubone umusaruro mwiza:

1.Kata umutwe w'agasanduku gafunga kugira ngo gahuze n'ingano y'agasaro ukeneye.

2. Hindura karitsiyo ifunga hanyuma uyishyire mu mbunda ikoresha icyuma gifunga.

3.Gerageza agasaro ku gice cy'ibisigazwa kugira ngo urebe ingano yabyo.

4.Nibiba ngombwa, shyiramo agapira k'inyongera hanyuma ureke byumye neza.

5. Shyira agakoresho ko gufunga mu ngingo zirenga santimetero imwe kugira ngo ugenzure uburebure bw'agakoresho ko gufunga.

6.Kanda imashini itera icyuma hanyuma ushyireho agafunga mu murongo uhamye kandi ugororotse.

7.Sukura isaro ukoresheje igikoresho cyangwa urutoki rwawe mbere yuko agakoresho gafunga gakora uruhu (ubusanzwe mu minota 10-20).

8. Sukura ibirenzeho ako kanya.

Gukiza

Ibifunga bya polyurethane bivura binyuze mu gukorana n'ubushuhe buri mu kirere. Uburyo bwo gushonga biterwa n'ubushyuhe n'ubushuhe. Dore ubuyobozi bugufi:

Ugomba kwirinda gukoraho cyangwa kwimura agakoresho gafunga kugeza gakize neza.

Amakosa yo kwirinda
