3.3 Muraayada borosilicate-ka sare waa hadda ka hor waxa ugu fiican adduunka oo loo isticmaali karo samaynta qalabka jeermiska-kaliya ee kiimikaad, rakibida tuubooyinka iyo aaladda shaybaadhka ee la isticmaalo.3.3 galaas borosilicate sare ah ayaa u gaaban galaas borosilicate ah oo leh isugeyn balaarineed (3.3 ± 0.1) × 10-6 / K-1, waxaa loogu hadlaa sida Pyex galaas caalami ah.

Shuruucda heerka caalamiga ah IS03587: Ku-habboonaanta dhalada iyo ku-habaynta dhalooyinka loo isticmaalo yutiilitida kiimikada waa inay qaataan 3.3 galaas borosilicate sare ah.

Tuubooyinka dhalooyinka iyo tas-hiilaadka Shirkadda Nantong Sanjing dhamaantood waxay qaataan dhalada borosilicate heerka caalamiga ah ee 3.3 ee wax soo saarka iyo wax soo saarka.

Tayada iska caabinta kulaylka

Muraayadaha waa kirishbooy liita iyo walxo jajaban, laakiin 3.3 galaas borosilicate way ka duwan tahay qaybaha kiimikada ee ka kooban 12.7% B2O3 taas oo si weyn u wanaajisa xasiloonida kulaylka.

IS03587 tilmaamo:

Wixii galaas borosilicate sare leh dhexroor <Φ100mm, kulaylkeeda-iska-caabbinta kama sarreeyaa 120℃;

Dhalada borosilicate ee sare leh dhexroorka>Φ100mm, kulaylkeeda iska caabbinta kama sarayso 110℃.
