Ibisobanuro by'igicuruzwa
Irangi rirwanya ubushyuhe bwinshi rya silicon, rizwi kandi nka irangi rirwanya ubushyuhe bwinshi, irangi rigabanyamo ibice bibiri: silicon y’umwimerere n’irangi rirwanya ubushyuhe bwinshi rya silicon inorganic. Irangi rirwanya ubushyuhe bwinshi, nk’uko izina ribigaragaza, ni ubwoko bw’irangi rishobora kwihanganira ubushyuhe bwinshi n’ibindi bihumanya.
- Ubushyuhe bwinshi mu nganda zikora irangi muri rusange buri hagati ya 100°C na 800°C.
- Irangi rikenewe kugira ngo rigumane imiterere ihamye mu bidukikije byavuzwe haruguru: nta gushwanyagurika, nta guturika, nta kwangirika, nta ifu, nta ingese, kandi ntirihinduke gato ibara.
Porogaramu y'ibicuruzwa
Irangi rya silikoni y’umwimerere rirwanya ubushyuhe bwinshi rikoreshwa cyane mu nkuta z’imbere n’inyuma z’amatanura n’amashyiga ashyushye, imiyoboro y’umuriro, imiyoboro y’amazi, imiyoboro y’amazi yumisha, imiyoboro y’amazi isohora umwuka, imiyoboro ya gaze ishyushye ishyushye, amatanura ashyushya, ibikoresho bihindura ubushyuhe, ndetse n’ibindi bintu bitari ibyuma n’ibyuma mu kurinda ubushyuhe bwinshi.
Ibipimo by'imikorere
- Uburyo bwo gupima ibimenyetso by'umushinga
Ishusho ya filime y'irangi: irangi ry'umukara ritagaragara neza, ubuso bworoshye. GBT1729
Ubushyuhe (ibikombe 4 by'ipamba): S20-35. GBT1723 Igihe cyo kumisha
Kumisha ameza kuri 25°C, h < 0.5, hakurikijwe GB/T1728
Ubushyuhe buringaniye kuri 25°C, h < 24
Kumisha kuri 200°C, h < 0.5
Ingufu z'ingaruka muri cm50, hakurikijwe GB/T1732
Guhinduka muri mm, h < 1, hakurikijwe GB/T1731
Igipimo cyo gufata, h < 2, hakurikijwe GB/T1720
Irabagirana, irabagirana cyangwa irabagirana
Ubudahangarwa bw'ubushyuhe (800°C, amasaha 24): Igipfundikizo gikomeza kuba cyiza, hamwe n'impinduka nke z'ibara byemerewe hakurikijwe GB/T1735
Uburyo bwo kubaka
- (1) Mbere yo gusukura: Ubuso bw'ubutaka bugomba gusukurwa n'umucanga kugira ngo bugere ku rwego rwa Sa2.5;
- (2) Hanagura ubuso bw'igikoresho ukoresheje agakoresho koroshye;
- (3) Hindura ubukana bw'igitambaro ukoresheje agakoresho gasanzwe gahuye n'agakoresho. Agakoresho gakoreshwa ni akadasanzwe, kandi ingano ni hafi: ku gipfundikizo kidakoresha umwuka - hafi 5% (ukurikije uburemere bwo gupfundikizo); ku gipfundikizo cy'umwuka - hafi 15-20% (ukurikije uburemere bwo gupfundikizo); ku koza - hafi 10-15% (ukurikije uburemere bw'ibikoresho);
- (4) Uburyo bwo kubaka: Gutera umwuka udakoresheje umwuka, gutera umwuka cyangwa koza. Icyitonderwa: Ubushyuhe bw'ubutaka mu gihe cyo kubaka bugomba kuba buri hejuru ya dogere selisiyusi 3, ariko ntiburenze dogere selisiyusi 60;
- (5) Gusiga irangi: Nyuma yo kuyisiga, izakira neza ku bushyuhe bw'icyumba igashyirwa mu bikorwa cyangwa ikanikwa mu cyumba kuri dogere selisiyusi 5 mu gihe cy'amasaha 0.5-1.0, hanyuma igashyirwa mu itanura rya dogere selisiyusi 180-200 kugira ngo iteke mu gihe cy'amasaha 0.5, ikakurwamo ikakonjeshwa mbere yo kuyikoresha.
Izindi ngingo z'ubwubatsi: Ubucucike - hafi 1.08g/cm3;
Ubugari bw'agapira k'umusenyi (agapira kamwe) 25um; Ubugari bw'agapira k'umusenyi butose 56um;
Aho gushyuha cyane - 27°C;
Ingano yo gusigaho irangi - 120 g/m2;
Igihe cyo gushyiramo irangi: amasaha 8-24 kuri 25°C cyangwa munsi yayo, amasaha 4-8 kuri 25°C cyangwa hejuru yayo
Igihe cyo kubika irangi: amezi 6. Nyuma y'iki gihe, ishobora gukoreshwa niba yatsinze igenzura kandi yujuje ibisabwa.
Igihe cyo kohereza ubutumwa: 10 Nzeri 2025
