Intangiriro ya tekiniki

3.3 Ikirahuri kinini cya borosilike ni cyo kintu cyiza cyane ku isi gishobora gukoreshwa mu gukora imiti igabanya ubukana bwa antiseptique, imiyoboro ikwiranye n’ibikoresho by’ibirahuri bikoreshwa muri laboratoire.3.3 ikirahure kinini cya borosilike ni kigufi kubirahuri bya borosilike hamwe na coefficient yo kwaguka kuri (3.3 ± 0.1） × 10-6 / K-1, byitwa ikirahuri cya Pyex mumahanga.

Ibipimo ngenderwaho mpuzamahanga IS03587: guhuza ibirahuri hamwe nibirahuri bikoreshwa mubikorwa bya shimi bigomba gufata ibirahuri 3.3 bya borosilike.

Umuyoboro w ibirahure nibikoresho muri Sosiyete ya Nantong Sanjing byose bifata ikirahuri mpuzamahanga cya 3.3 borosilicate ikirahure cyo gukora no gukora.

Ubwiza bwo kurwanya ubushyuhe

Ikirahure nuyobora nabi kandi ibintu byoroshye, ariko ikirahuri cya borosilike 3.3 kiratandukanye kubigize imiti irimo 12.7% ya B2O3 iteza imbere cyane ubushyuhe bwayo.

IS03587 ibisobanuro:

Kubirahuri binini bya borosilike ifite diameter <Φ100mm, ubushyuhe bwayo bwo kurwanya ubushyuhe ntiburenga 120 ℃;

Kubirahuri binini bya borosilike ifite diameter> Φ100mm, ubushyuhe bwayo bwo kurwanya ubushyuhe ntiburenga 110 ℃.

Mumuvuduko uhoraho （20 ℃ -100 ℃）

Gushyushya imitungo

Ikigereranyo cyo gutwara ubushyuhe: （20-100 ℃） λ = 1.2Wm-1K-1

Impuzandengo yubushyuhe bwihariye: Cp = 0.98Jg-1K-1
