Yuav Khoov Hlau Tube li cas

Tsawg melting point alloys tuaj yeem siv los ua cov ntaub ntawv muab tub lim thaum khoov nyias-walled hlau luj tshib rau hauv me me radii lossis cov duab nyuaj. Resin, asphalt, xuab zeb, txhuas, thiab lwm yam siv yav dhau los yog siv los ua cov ntaub ntawv sau. Nrog rau cov ntaub ntawv sau, sab hauv yog yooj yim txav (xuab zeb), thiab cov kab nrib pleb (resin, txhuas) tau yooj yim tsim, thiab cov kav dej yog khoov thiab puas. Qhov qis melting point alloy filling khoom yog yooj yim rau kev khiav lag luam, muaj ib tug siab yield, thiab yog yooj yim rau sau. Tam sim no cov khoom ntim no tau siv dav hauv cov yeeb nkab dabtsi yog khoov ntawm lub ntsuas siab, cov roj yeeb nkab ntawm lub tshuab, thiab lwm yam.

Ntoo cov hlau (70 degree alloy) muaj cov ntsiab lus melting tsawg thiab pheej yig tus nqi, nws yog qhov kev xaiv zoo tshaj plaws raws li khoov raj muab tub lim.
